-CLooG is a software which generates loops for scanning Z-polyhedra. That is,
-CLooG finds the code or pseudo-code where each integral point of one or more
-parametrized polyhedron or parametrized polyhedra union is reached. CLooG is
-designed to avoid control overhead and to produce a very efficient code.
-
-Its input is some data on the polyhedra to scan, basically the system of
-affine inequalities that define them, and a context that defines some
-properties known on the parameters if any. The output is the pseudo scanning
-code. Many facilities are provided to generate a near-to-be-compileable code,
-and every useful functions to generate the code may be called from the CLooG
-library.

-
-If you obtained CLooG from the git repository, then you first
-need to obtain the submodules and create a configure script.
-
-  ./get_submodules.sh
-  ./autogen.sh
-
-The first step is only needed if you plan on using the isl backend.
-
-The configure shell script attempts to guess correct values for various
-system-dependent variables used during compilation. It uses those values to
-create a Makefile. The file configure.ac is used to create configure by a
-program called autoconf.  You only need configure.ac if you want to change
-it or regenerate configure using a newer version of autoconf.
-
-The simplest way to compile this package is:
-cd to the directory containing the package's source code and type 
-
-  ./configure
-
-to configure the package for your system (while running, configure prints
-some messages telling which features it is checking for). To compile the
-package, type
-
-  make
-  
-
-to install the program and/or the library, type
-
-  make install
-
-you can remove the program binaries and object files from the source code
-directory by typing
-  
-  make clean
-  
-To also remove the files that configure created (so you can compile the
-package for a different kind of computer) type
-  
-  make distclean
-
-#   **-------------------------------------------------------------------**
-#   **                           III. Options                            **
-#   **-------------------------------------------------------------------**/
-
-By default,  make will install the package's files in /usr/local/bin,
-/usr/local/lib, etc. You can specify an installation prefix other than 
-/usr/local by giving onfigure the option --prefix=PATH.
-
-By default, configure will use the isl that comes bundled with CLooG.
-Using the --with-isl option of configure the user can specify that "no" isl,
-a previously installed ("system") isl or a "build" isl should be used.
-In the latter case, the user should also specify the build location
-using --with-isl-builddir=PATH.  In case of an installed isl,
-the installation location can be specified using the
---with-isl-prefix=PATH and --with-isl-exec-prefix=PATH options of configure.
-
-By default, configure will seek the PolyLib in standard locations.
-If necessary, you can specify the PolyLib's path by giving configure the
-option --with-polylib-prefix=PATH and/or --with-polylib-exec-prefix=PATH.
-
-By default, configure will seek the GMP library in standard locations.
-If necessary, you can specify the GMP's path by giving configure the
-option --with-gmp-prefix=PATH and/or --with-gmp-exec-prefix=PATH.
-
-By default, when using the PolyLib backend,
-CLooG and its library are built using 64 bits integer
-representation. You can choose to specify explicitly others integer
-representations by using:
---with-bits=32  for 32 bits integers,
---with-bits=64  for 64 bits integers (default),
---with-bits=gmp for multiple precision integers.

-
-To run CLooG, simply type 'cloog', optionally followed by the name of an
-input file. You can type 'cloog -h' or 'cloog --help' for some help.
-For more informations, please check the ./doc subdirectory.

-#   **-------------------------------------------------------------------**/
-
-1. What does CLooG means ?
-
-CLooG is the Chunky LOOp Generator, Chunky is an automatic loop optimizer for
-data locality. CLooG is a completely independent part of the Chunky project.
-Pronounce 'CLooG' as 'klug', which means 'sly' in german :-).
-
-2. CLooG do not compile, what should I do ?
-
-CLooG should compile everywhere (assuming that PolyLib is still there), thus
-there is a problem or the documentation is not clear, in both case it is
-necessary to ask the author(s) !
-
-3. I need a feature that CLooG do not implement, what should I do ?
-
-There are two ways. First, CLooG is a LGPL software and library. So you
-are welcome to improve it yourself ;-) ! Many project have been successful, it
-is -maybe- a sign that this is not too hard to put your hands inside the
-source. Second, just ask the author(s) :-) ! Maybe a lot of people would be
-interessed by such feature, maybe many people asked for it before, maybe it's
-trivial to implement (and even)... Please just never hesitate to ask the
-author(s) !
-
-4. I implemented a cool feature, can I submit it ?
-
-Obviously you are welcome to send the author(s) any improvement. But obviously
-we are quite careful with readability, correctness and stability, and the
-author(s) will read, check and check again any contribution before including it.
-Thus, it can take time... There are few basic rules to write contributions:
-- (1) Do never change the indentation of any part of the code that is not yours.
-- (2) Do never send codes that use more than 80 columns.
-- (3) Do never send codes without a lot of comments in (bad or good) english.
-- (4) Do never send codes with obscure and/or non-english variable names.
-- (5) Use C89, just C, only C (note: "//" comments are not C89,
-  variable declaration elsewhere than at the beginning of a block, is not C89).
-- (6) Read doc/SubmittingPatches
-Please understand that in order to live for a long time, and to be used in many
-projects the very first priority for CLooG is to be readable and documented.
-
-5. Is CLooG bug free ?
-
-No, who can ? ClooG is a complex program, and we do not pretend it to be bug
-free. Nevertheless because it has been tested and tested, we are fairly sure
-that CLooG results with default options have good chances to be satisfactory.
-If you find a result that looks strange, inadequate or incorrect, please send:
-- (1) The input file to the author(s).
-- (2) The output.
-- (3) The first line given by typing 'cloog -v'.
-- (4) All your command line options to achieve the result.
-We will try to explain the result or to fix the problem as soon as possible.
-
-6. How can I contact the author(s) ?
-
-Just send a mail to cloog-development@googlegroups.com

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`configure' configures cloog 0.16.3 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:

-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-

-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-@chapter Introduction
-CLooG is a free software and library generating loops for scanning Z-polyhedra.
-That is, it finds a code (e.g. in C, FORTRAN...) that reaches each integral
-point of one or more parameterized polyhedra. CLooG has been originally
-written to solve the code generation problem for optimizing compilers based on
-the polytope model. Nevertheless it is used now in various area, e.g., to build
-control automata for high-level synthesis or to find the best polynomial
-approximation of a function. CLooG may help in any situation where scanning
-polyhedra matters. It uses the best state-of-the-art code generation
-algorithm known as the Quiller@'e et al. algorithm (@pxref{Qui00})
-with our own improvements and extensions (@pxref{Bas04}).
-The user has full control on generated code quality.
-On one hand, generated code size has to be tuned for sake of
-readability or instruction cache use. On the other hand, we must ensure that
-a bad control management does not hamper performance of the generated code,
-for instance by producing redundant guards or complex loop bounds.
-CLooG is specially designed to avoid control overhead and to produce a very
-efficient code.
-
-CLooG stands for @emph{Chunky Loop Generator}: it is a part of the Chunky
-project, a research tool for data locality improvement (@pxref{Bas03a}).
-It is designed
-also to be the back-end of automatic parallelizers like LooPo (@pxref{Gri04}).
-Thus it is very
-compilable code oriented and provides powerful program transformation
-facilities. Mainly, it allows the user to specify very general schedules where, 
-e.g., unimodularity or invertibility of the transformation doesn't matter.
-
-The current version is still under
-evaluation, and there is no guarantee that the upward compatibility
-will be respected (but the previous API has been stable for two years,
-we hope this one will be as successful -and we believe it-).
-A lot of reports are necessary to freeze the library
-API and the input file shape. Most API changes from 0.12.x to 0.14.x
-have been requested by the users themselves.
-Thus you are very welcome and encouraged
-to post reports on bugs, wishes, critics, comments, suggestions or
-successful experiences in the forum of @code{http://www.CLooG.org}
-or to send them to cedric.bastoul@@inria.fr directly.

-@node Basics
-@section Basically, what's the point ?
-If you want to use CLooG, this is because you want to scan or to find
-something inside the integral points of a set of polyhedra. There are many
-reasons for that. Maybe you need the generated code itself because it
-actually implements a very smart program transformation you found.
-Maybe you want to use the generated code
-because you know that the solution of your problem belongs to the integral
-points of those damned polyhedra and you don't know which one. Maybe you just
-want to know if a polyhedron has integral points depending on some parameters,
-which is the lexicographic minimum, maximum, the third on the basis of the
-left etc. Probably you have your own reasons to use CLooG.
-
-Let us illustrate a basic use of CLooG. Suppose we have a set of affine
-constraints that describes a part of a whatever-dimensional space,
-called a @strong{domain}, and we
-want to scan it. Let us consider for instance the following set of constraints
-where @samp{i}
-and @samp{j} are the unknown (the two dimensions of the space) and
-@samp{m} and @samp{n} are the parameters (some symbolic constants):
-@example
-@group
-2<=i<=n
-2<=j<=m
-j<=n+2-i
-@end group
-@end example
-Let us also consider that we have a partial knowledge of the parameter values,
-called the @strong{context}, expressed as affine constraints as well,
-for instance:
-@example
-@group
-m>=2
-n>=2
-@end group
-@end example
-Note that using parameters is optional, if you are not comfortable with
-parameter manipulation, just replace them with any scalar value that fits
-@code{m>=2} and @code{n>=2}.
-A graphical representation of this part of the 2-dimensional space, where
-the integral points are represented using heavy dots would be for instance:
-
-@image{images/basic,6cm}
-
-The affine constraints of both the domain and the context are what we will
-provide to CLooG as input (in a particular shape that will be described later).
-The output of CLooG is a pseudo-code to scan the integral points of the
-input domain according to the context:
-@example
-@group
-for (i=2;i<=n;i++) @{
-  for (j=2;j<=min(m,-i+n+2);j++) @{    
-    S1(i,j) ;
-  @}
-@}
-@end group
-@end example
-If you felt such a basic example is yet interesting, there is a good chance
-that CLooG is appropriate for you. CLooG can do much more: scanning several
-polyhedra or unions of polyhedra at the same time, applying general affine
-transformations to the polyhedra, generate compilable code etc. Welcome
-to the CLooG's user's guide !
-
-@node Scattering
-@section Defining a Scanning Order: Scattering Functions
-In CLooG, domains only define the set of integral points to scan and their
-coordinates. In particular, CLooG is free to choose the scanning order for
-generating the most efficient code. This means, for optimizing/parallelizing
-compiler people, that CLooG doesn't make any speculation on dependences on and
-between statements (by the way, it's not its job !).
-For instance, if an user give to
-CLooG only two domains @code{S1:1<=i<=n}, @code{S2:1<=i<=n} and the context
-@code{n>=1}, the following pseudo-codes are considered to be equivalent:
-
-@example
-@group
-/* A convenient target pseudo-code. */
-for (i=1;i<=N;i++) @{
- S1(i) ;
-@}
-for (i=1;i<=N;i++) @{
- S2(i) ;
-@}
-@end group
-@end example
-
-@example
-@group
-/* Another convenient target pseudo-code. */
-for (i=1;i<=N;i++) @{
- S1(i) ;
- S2(i) ;
-@}
-@end group
-@end example
-
-The default behaviour
-of CLooG is to generate the second one, since it is optimized in control. 
-It is right if there are no data dependences
-between @code{S1} and @code{S2}, but wrong otherwise. 
-
-Thus it is often useful to force scanning to respect a given order. This can be
-done in CLooG by using @strong{scattering functions}. Scattering is a
-shortcut for scheduling, allocation, chunking functions and the like we can
-find in the restructuring compilation literature. There are a lot of reasons
-to scatter the integral points of the domains (i.e. the statement instances
-of a program, for compilation people), parallelization or optimization are good
-examples. For instance, if the user wants for any reason to set some
-precedence constraints between the statements of our example above
-in order to force the generation of the
-first code, he can do it easily by setting (for example) the following
-scheduling functions:
-
-@tex
-$$\theta _{S1}(i) =  (1)$$
-$$\theta _{S2}(j) =  (2)$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i) = (1)
-T_S2(j) = (2)
-@end group
-@end example
-@end ifnottex
-
-This scattering means that each integral point of the domain @code{S1}
-is scanned at logical date @code{1} while each integral point of the domain
-@code{S2} is scanned at logical date @code{2}. As a result, the whole
-domain @code{S1} is scanned before domain @code{S2} and the first code in our
-example is generated.
-
-The user can set every kind of affine scanning order thanks to the
-scattering functions. Each domain has its own scattering function and
-each scattering function may be multi-dimensional. A multi-dimensional logical
-date may be seen as classical date (year,month,day,hour,minute,etc.) where
-the first dimensions are the most significant. Each scattering dimension
-may depend linearly on the original dimensions (e.g., @code{i}), the
-parameters (e.g., @code{n}) ans scalars (e.g., @code{2}).
-
-A very useful example of multi-dimensional scattering functions is, for
-compilation people, the scheduling of the original program.
-The basic data to use for code generation are statement iteration domains.
-As we saw, these data are not sufficient to rebuild the original
-program (what is the ordering between instances of different statements ?).
-The missing data can be put in the scattering functions as the original
-scheduling. The method to compute it is quite simple (@pxref{Fea92}). The idea is to
-build an abstract syntax tree of the program and to read the scheduling for
-each statement. For instance, let us consider the following implementation of
-a Cholesky factorization:
-
-@example
-@group
-/* A Cholesky factorization kernel. */
-for (i=1;i<=N;i++) @{
-  for (j=1;j<=i-1;j++) @{
-    a[i][i] -= a[i][j] ;           /* S1 */
-  @}
-  a[i][i] = sqrt(a[i][i]) ;        /* S2 */
-  for (j=i+1;j<=N;j++) @{
-    for (k=1;k<=i-1;k++) @{
-      a[j][i] -= a[j][k]*a[i][k] ; /* S3 */
-    @}
-    a[j][i] /= a[i][i] ;           /* S4 */
-    @}
-  @}
-@}
-@end group
-@end example
-
-The corresponding abstract syntax tree is given in the following figure.
-It directly gives the scattering functions (schedules) for all the
-statements of the program.
-
-@image{images/tree,6cm}
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i,j)^T    &$=  (0,i,0,j,0)^T$\cr
-                \theta _{S2}(i)        &$=  (0,i,1)^T$\cr
-                \theta _{S3}(i,j,k)^T  &$=  (0,i,2,j,0,k,0)^T$\cr
-                \theta _{S4}(i,j)^T    &$=  (0,i,2,j,1)^T$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i,j)^T   = (0,i,0,j,0)^T
-T_S2(i)       = (0,i,1)^T
-T_S3(i,j,k)^T = (0,i,2,j,0,k,0)^T
-T_S4(i,j)^T   = (0,i,2,j,1)^T
-@end group
-@end example
-@end ifnottex
-
-These schedules depend on the iterators and give for each instance of each
-statement a unique execution date. Using such scattering functions allow
-CLooG to re-generate the input code.

-@section A First Example
-CLooG takes as input a file that must be written accordingly to a grammar
-described in depth in a further section (@pxref{Writing The Input File}). 
-Moreover it supports many options to tune the target code presentation or
-quality as discussed in a dedicated section (@pxref{Calling CLooG}).
-However, a basic use
-of CLooG is not very complex and we present in this section how to generate the
-code corresponding to a basic example discussed earlier (@pxref{Basics}).
-
-The problem is to find the code that scans a 2-dimensional polyhedron
-where @samp{i} and @samp{j} are the unknown (the two dimensions of the space)
-and @samp{m} and @samp{n} are the parameters (the symbolic constants),
-defined by the following set of constraints:
-@example
-@group
-2<=i<=n
-2<=j<=m
-j<=n+2-i
-@end group
-@end example
-@noindent We also consider a partial knowledge of the parameter values,
-expressed thanks to the following affine constraints:
-@example
-@group
-m>=2
-n>=2
-@end group
-@end example
-
-An input file that corresponds to this problem, and asks for a generated
-code in C, may be the following. Note that we do not describe here precisely
-the structure and the components of this file (@pxref{Writing The Input File}
- for such information, if you feel it necessary):
-
-@example
-# ---------------------- CONTEXT ----------------------
-c # language is C
-
-# Context (constraints on two parameters)
-2 4                   # 2 lines and 4 columns
-# eq/in m  n  1         eq/in: 1 for inequality >=0, 0 for equality =0
-    1   1  0 -2       # 1*m + 0*n -2*1 >= 0, i.e. m>=2
-    1   0  1 -2       # 0*m + 1*n -2*1 >= 0, i.e. n>=2
-
-1 # We want to set manually the parameter names

-    1  -1  0  0  1  0 # i <= n
-    1   0  1  0  0 -2 # j >= 2

-@end example
-
-This file may be called @samp{basic.cloog}
-(this example is provided in the CLooG distribution as
-@code{test/manual_basic.cloog}) and we can ask CLooG to process it
-and to generate the code by a simple calling to CLooG with this file as input:
-@samp{cloog basic.cloog}. By default, CLooG will print the generated code in
-the standard output:
-
-@example

-@node Writing The Input File
-@section Writing The Input File
-The input text file contains a problem description, i.e. the context,
-the domains and the scattering functions.
-Because CLooG is very 'compilable code generation oriented', we can associate
-some additional informations to each domain. We call this association a
-@emph{statement}. The set of all informations is 
-called a @emph{program}. The input file respects the grammar below
-(terminals are preceded by "_"):
-
-@example
-File             ::= Program
-Program          ::= Context Statements Scattering
-Context          ::= Language      Domain_union   Naming
-Statements       ::= Nb_statements Statement_list Naming
-Scatterings      ::= Nb_functions  Scattering_list Naming
-Naming           ::= Option Name_list
-Name_list        ::= _String   Name_list      | (void)
-Statement_list   ::= Statement Statement_list | (void)
-Domain_list      ::= _Domain   Domain_list    | (void)
-Scattering_list  ::= Domain_union Scattering_list | (void)
-Statement        ::= Iteration_domain 0 0 0
-Iteration_domain ::= Domain_union
-Domain_union     ::= Nb_domains Domain_list
-Option           ::= 0 | 1
-Language         ::= c | f
-Nb_statements    ::= _Integer
-Nb_domains       ::= _Integer
-Nb_functions     ::= _Integer
-@end example
-
-Note: if there is only one domain in a @samp{Domain_union},
-i.e., if @samp{Nb_domains} is 1, then this 1 may be omitted.
-
-@itemize @bullet
-@item  @samp{Context} represents the informations that are
-       shared by all the statements. It consists on
-       the language used (which can be @samp{c} for C or @samp{f} for FORTRAN 90)
-       and the global constraints on parameters.
-       These constraints are essential
-       since they give to CLooG the number of parameters. If there is no
-       parameter or no constraints on parameters, just give a constraint
-       always satisfied like @math{1 \geq 0}. @samp{Naming} sets the parameter
-       names.
-       If the naming option @samp{Option} is 1, parameter names will be read
-       on the next line. There must be exactly as many names as parameters.
-       If the naming option @samp{Option} is 0, parameter names are
-       automatically generated. The name of the first parameter will
-       be @samp{M}, and the name of the @math{(n+1)^{th}} parameter directly
-       follows the name of the @math{n^{th}} parameter in ASCII code.
-       It is the user responsibility to ensure that parameter names,
-       iterators and scattering dimension names are different. 
-@item  @samp{Statements} represents the informations on the statements.
-       @samp{Nb_statements} is the number of statements in the program, 
-       i.e. the number of @samp{Statement} items in the @samp{Statement_list}.
-       @samp{Statement} represents the informations on a given statement.
-       To each statement is associated a domain
-       (the statement iteration domain: @samp{Iteration_domain}) and three
-       zeroes that represents future options.
-       @samp{Naming} sets the iterator names. If the naming option
-       @samp{Option} is 1, the iterator names
-       will be read on the next line. There must be exactly as many names as
-       nesting level in the deepest iteration domain. If the naming option
-       @samp{Option} is 0, iterator names are automatically generated.
-       The iterator name of the outermost loop will be @samp{i}, and the
-       iterator name of the loop at level @math{n+1} directly follows the 
-       iterator name of the loop at level @math{n} in ASCII code. 
-@item  @samp{Scatterings} represents the informations on scattering functions.
-       @samp{Nb_functions} is the number of functions (it must be
-       equal to the number of statements or 0 if there is no scattering
-       function). The functions themselves are represented through
-       @samp{Scattering_list}.
-       @samp{Naming} sets the scattering dimension names. If the naming option
-       @samp{Option} is 1, the scattering dimension names will be read on the
-       next line.
-       There must be exactly as many names as scattering dimensions. If the
-       naming option @samp{Option} is 0, scattering dimension names are automatically
-       generated. The name of the @math{n^{th}} scattering dimension
-       will be @samp{cn}.

-@node Domain Representation
-@subsection Domain Representation
-As shown by the grammar, the input file describes the various informations
-thanks to characters, integers and domains. Each domain is defined by a set of
-constraints in the PolyLib format (@pxref{Wil93}). They have the
-following syntax:
-@enumerate
-@item some optional comment lines beginning with @samp{#},
-@item the row and column numbers, possibly followed by comments,
-@item the constraint rows, each row corresponds to a constraint the
-      domain have to satisfy. Each row must be on a single line and is possibly
-      followed by comments. The constraint is an equality @math{p(x) = 0} if the
-      first element is 0, an inequality  @math{p(x) \geq 0} if the first element
-      is 1. The next elements are the unknown coefficients, followed by
-      the parameter coefficients. The last element is the constant factor.
-@end enumerate
-For instance, assuming that @samp{i}, @samp{j} and @samp{k} are iterators and
-@samp{m} and @samp{n} are parameters, the domain defined by the following
-constraints :
-
-@tex
-$$
-\hbox{$ \cases{ -i     + m &$\geq 0$\cr
-                    -j + n &$\geq 0$\cr
-                 i + j - k &$\geq 0$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-   -i + m >= 0
-   -j + n >= 0
-i + j - k >= 0
-@end group
-@end example
-@end ifnottex
-
-@noindent can be written in the input file as follows :
-
-@example
-@group
-# This is the domain
-3 7                      # 3 lines and 7 columns
-# eq/in i  j  k  m  n  1 
-    1  -1  0  0  1  0  0 #    -i + m >= 0
-    1   0 -1  0  0  1  0 #    -j + n >= 0
-    1   1  1 -1  0  0  0 # i + j - k >= 0
-@end group
-@end example
-
-Each iteration domain @samp{Iteration_domain} of a given statement
-is a union of polyhedra
-@samp{Domain_union}. A union is defined by its number of elements
-@samp{Nb_domains} and the elements themselves @samp{Domain_list}.
-For instance, let us consider the following pseudo-code:
-
-@example
-@group
-for (i=1;i<=n;i++) @{
-  if ((i >= m) || (i <= 2*m))
-    S1 ;
-  for (j=i+1;j<=m;j++)
-    S2 ;
-@} 
-@end group
-@end example
-
-@noindent The iteration domain of @samp{S1} can be divided into two
-polyhedra and written in the input file as follows:
-
-@example
-@group
-2 # Number of polyhedra in the union
-# First domain
-3 5                # 3 lines and 5 columns
-# eq/in i  m  n  1 
-    1   1  0  0 -1 #  i >= 1
-    1  -1  0  1  0 #  i <= n
-    1   1 -1  0  0 #  i >= m
-# Second domain
-3 5                # 3 lines and 5 columns
-# eq/in i  m  n  1 
-    1   1  0  0 -1 #  i >= 1
-    1  -1  0  1  0 #  i <= n
-    1  -1  2  0  0 #  i <= 2*m
-@end group
-@end example
-
-@node Scattering Representation
-@subsection Scattering Function Representation
-Scattering functions are depicted in the input file thanks a representation
-very close to the domain one.
-An integer gives the number of functions @samp{Nb_functions} and each function
-is represented by a domain. Each line of the domain corresponds to an equality
-defining a dimension of the function. Note that at present
-(CLooG @value{VERSION})
-@strong{all functions must have the same scattering dimension number}. If a
-user wants to set scattering functions with different dimensionality, he has
-to complete the smaller one with zeroes to reach the maximum dimensionality.
-For instance, let us consider the following code and
-scheduling functions:
-
-@example
-@group
-for (i=1;i<=n;i++) @{
-  if ((i >= m) || (i <= 2*m))
-    S1 ;
-  for (j=i+1;j<=m;j++)
-    S2 ;
-@} 
-@end group
-@end example
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i)      &$=  (i,0)^T$\cr
-                \theta _{S2}(i,j)^T  &$=  (n,i+j)^T$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i)     = (i,0)^T
-T_S2(i,j)^T = (n,i+j)^T
-@end group
-@end example
-@end ifnottex
-
-
-@noindent This scheduling can be written in the input file as follows:
-
-@example
-@group
-2 # Number of scattering functions
-# First function
-2 7                          # 2 lines and 7 columns
-# eq/in c1 c2  i  m  n  1 
-    0    1  0 -1  0  0  0    #  c1 = i
-    0    0  1  0  0  0  0    #  c2 = 0
-# Second function
-2 8                          # 2 lines and 8 columns
-# eq/in c1 c2  i  j  m  n  1 
-    0    1  0  0  0  0 -1  0 #  c1 = n
-    0    0  1 -1 -1  0  0  0 #  c2 = i+j
-@end group
-@end example
-The complete input file for the user who wants to generate the code for this
-example with the preceding scheduling would be
-(this file is provided in the CLooG distribution

-@node Last Depth to Optimize Control
-@subsection Last Depth to Optimize Control @code{-l <depth>}
-
-@code{-l <depth>}: this option sets the last loop depth to be optimized in
-control. The higher this depth, the less control overhead.
-For instance, with some input file, a user can generate
-different pseudo-codes with different @code{depth} values as shown below.
-@example
-@group
-/* Generated using a given input file and @strong{option -l 1} */
-for (i=0;i<=M;i++) @{
-  S1 ;
-  for (j=0;j<=N;j++) @{
-    S2 ;
-  @}
-  for (j=0;j<=N;j++) @{
-    S3 ;
-  @}
-  S4 ;
-@}
-@end group
-@end example
-@example

-/* Generated using the same input file but @strong{option -l 2} */
-for (i=0;i<=M;i++) @{
-  S1 ;
-  for (j=0;j<=N;j++) @{
-    S2 ;
-    S3 ;
-  @}
-  S4 ;
-@}
-@end group
-@end example
-     In this example we can see that this option can change the operation
-     execution order between statements. Let us remind that CLooG does not
-     make any speculation on dependences between statements
-     (@pxref{Scattering}). Thus if nothing (i.e. scattering functions)
-     forbids this, CLooG considers the above codes to be equivalent.
-     If there is no scattering functions, the minimum value for @code{depth}
-     is 1 (in the case of 0, the user doesn't really need a loop generator !),
-     and the number of scattering dimensions otherwise (CLooG will warn the
-     user if he doesn't respect such constraint).
-     The maximum value for depth is -1 (infinity).
-     Default value is infinity.
-
-@node First Depth to Optimize Control
-@subsection First Depth to Optimize Control @code{-f <depth>}
-
-     @code{-f <depth>}: this option sets the first loop depth to be optimized
-     in control. The lower this depth, the less control overhead (and the longer
-     the generated code). For instance, with some input file, a user
-     can generate different pseudo-codes with different @code{depth} values
-     as shown below.
-     The minimum value for @code{depth} is 1, and the
-     maximum value is -1 (infinity).
-     Default value is 1.
-@example
-@group
-/* Generated using a given input file and @strong{option -f 3} */
-for (i=1;i<=N;i++) @{
-  for (j=1;j<=M;j++) @{

-
-@node Simple Convex Hull
-@subsection  Simple Convex Hull @code{-sh <boolean>}
-
-     @code{-sh <boolean>}: this option enables (@code{boolean=1})
-     or forbids (@code{boolean=0}) the use of an overapproximation
-     of the convex hull that may be easier to compute
-     (especially in the isl backend) and that may result in
-     simpler bounds.
-     This option works only for generated code without
-     code duplication (it means, you have to tune @code{-f} and
-     @code{-l} options first to generate only a loop nest with internal
-     guards). For instance, with the input file @code{test/union.cloog}, a user
-     can generate different pseudo-codes  as shown below.
-     Default value is 0.
-@example
-@group
-/* Generated using test/union.cloog and @strong{option -f -1 -l 2 -override} */
-for (i=0;i<=11;i++) @{

-
-     @code{-otl <boolean>}: this option allows (@code{boolean=1}) or

-@node First Level for Spreading 
-@subsection First Level for Spreading @code{-fsp <level>}
-
-     @code{-fsp <level>}: it can be useful to set a
-     first level to begin equality spreading. Particularly when using
-     scattering functions, the user may want to see the scattering dimension
-     values instead of spreading or hiding them. If user has set a
-     spreading, @code{level} is
-     the first level to start it. Default value is 1.
-@example

-
-@node Statement Block  
-@subsection Statement Block @code{-block <boolean>}
-
-     @code{-block <boolean>}: this option allows (@code{boolean=1}) to
-     create a statement block for each new iterator, even if there is only
-     an equality. This can be useful in order to parse the generated
-     pseudo-code. When @code{boolean} is set to 0 or when the generation
-     language is FORTRAN, this feature is disabled. Default value is 0.
-@example
-@group

-@node Loop Strides 
-@subsection Loop Strides @code{-strides <boolean>}
-
-     @code{-strides <boolean>}: this options allows (@code{boolean=1}) to
-     handle non-unit strides for loop increments. This can remove a lot of
-     guards and make the generated code more efficient. Default value is 0.
-@example

-@end group
-@end example
-
-
-@node Unrolling
-@subsection First Depth to Unroll @code{-first-unroll <depth>}
-
-    @code{-first-unroll <depth>}: this option sets the first loop depth
-    to unroll.  Note that a loop is only unrolled when it is supported
-    by the backend.  In case of the isl backend, a loop is unrolled
-    if it has a lower bound that can only be incremented
-    a fixed (non-parametric) amount of times.
-
-
-@node Compilable Code
-@subsection Compilable Code @code{-compilable <value>}
-
-     @code{-compilable <value>}: this options allows (@code{value} is not 0)
-     to generate a compilable code where all parameters have the integral value
-     @code{value}. This option creates a macro for each statement. Since
-     CLooG do not know anything about the statement sources, it fills the
-     macros with a basic increment that computes the total number of
-     scanned integral points. The user may change easily the macros according
-     to his own needs. This option is possible only if the generated code is
-     in C. Default value is 0.
-@example
-@group
-/* Generated using a given input file and @strong{option -compilable 0} */
-for (i=0;i<=n;i++) @{
-  for (j=0;j<=n;j++) @{

-@section A Full Example
-
-Let us consider the allocation problem of a Gaussian elimination, i.e. we want
-to distribute the various statement instances of the compute kernel onto
-different processors. The original code is the following:
-@example
-@group
-for (i=1;j<=N-1;i++) @{
-  for (j=i+1;j<=N;j++) @{
-    c[i][j] = a[j][i]/a[i][i] ;    /* S1 */
-    for (k=i+1;k<=N;k++) @{
-      a[j][k] -= c[i][j]*a[i][k] ; /* S2 */
-    @}
-  @}
-@}
-@end group
-@end example
-
-@noindent The best affine allocation functions can be found by any good automatic
-parallelizer like LooPo (@pxref{Gri04}):
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i,j)^T    &$=  (i)$\cr
-                \theta _{S2}(i,j,k)^T  &$=  (k)$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i,j)^T   = (i)
-T_S2(i,j,k)^T = (k)
-@end group
-@end example
-@end ifnottex
-
-@noindent To ensure that on each processor, the set of statement instances is
-executed according to the original ordering, we add as minor scattering
-dimensions the original scheduling (@pxref{Scattering}):
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i,j)^T    &$=  (i,0,i,0,j,0)^T$\cr
-                \theta _{S2}(i,j,k)^T  &$=  (k,0,i,0,j,1,k,0)^T$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i,j)^T   = (i,0,i,0,j,0)^T
-T_S2(i,j,k)^T = (k,0,i,0,j,1,k,0)^T
-@end group
-@end example
-@end ifnottex
-
-@noindent To ensure that the scattering functions have the same dimensionality, we
-complete the first function with zeroes
-(this is a CLooG @value{VERSION} and previous versions requirement,
-it should be removed in a future version, don't worry it's absolutely legal !):
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i,j)^T    &$=  (i,0,i,0,j,0,0,0)^T$\cr
-                \theta _{S2}(i,j,k)^T  &$=  (k,0,i,0,j,1,k,0)^T$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i,j)^T   = (i,0,i,0,j,0,0,0)^T
-T_S2(i,j,k)^T = (k,0,i,0,j,1,k,0)^T
-@end group
-@end example
-@end ifnottex

-Calling CLooG, with for instance the command line

-to implement, e.g., MPI calls, which is not shown here may
-result in dramatic speedups !

-@chapter Using the CLooG Library
-The CLooG Library was implemented to allow the user to call CLooG
-directly from his programs, without file accesses or system calls. The
-user only needs to link his programs with C libraries. The CLooG
-library mainly provides one function (@code{cloog_clast_create_from_input})
-which takes as input the problem
-description with some options, and returns the data structure corresponding
-to the generated code (a @code{struct clast_stmt} structure)
-which is more or less an abstract syntax tree.
-The user can work with this data structure and/or use
-our pretty printing function to write the final code in either C or FORTRAN.
-Some other functions are provided for convenience reasons.
-These functions as well as the data structures are described in this section.

-@subsection CloogState
-@example
-@group
-CloogState *cloog_state_malloc(void);
-void cloog_state_free(CloogState *state);
-@end group
-@end example
-
-@noindent The @code{CloogState} structure is (implicitly) needed to perform
-any CLooG operation.  It should be created using @code{cloog_state_malloc}
-before any other CLooG objects are created and destroyed using
-@code{cloog_state_free} after all objects have been freed.
-It is allowed to use more than one @code{CloogState} structure at
-the same time, but an object created within the state of a one
-@code{CloogState} structure is not allowed to interact with an object
-created within the state of an other @code{CloogState} structure.
-
-
-@node CloogMatrix
-@subsection CloogMatrix
-
-@noindent The @code{CloogMatrix} structure is equivalent to the PolyLib
-@code{Matrix} data structure (@pxref{Wil93}). This structure is devoted to
-represent a set of constraints.
-
-@example
-@group
-struct cloogmatrix
-@{ unsigned NbRows ;    /* Number of rows. */
-  unsigned NbColumns ; /* Number of columns. */
-  cloog_int_t **p;     /* Array of pointers to the matrix rows. */
-  cloog_int_t *p_Init; /* Matrix rows contiguously in memory. */
-@};
-typedef struct cloogmatrix CloogMatrix;
-
-CloogMatrix *cloog_matrix_alloc(unsigned NbRows, unsigned NbColumns);
-void cloog_matrix_print(FILE *foo, CloogMatrix *m);
-void cloog_matrix_free(CloogMatrix *matrix);
-@end group
-@end example
-
-@noindent The whole matrix is stored in memory row after row at the
-@code{p_Init} address. @code{p} is an array of pointers where
-@code{p[i]} points to the first element of the @math{i^{th}} row.
-@code{NbRows} and @code{NbColumns} are respectively the number of
-rows and columns of the matrix. 
-Each row corresponds to a constraint. The first element of each row is an
-equality/inequality tag. The
-constraint is an equality @math{p(x) = 0} if the first element is 0, but it is
-an inequality @math{p(x) \geq 0} if the first element is 1.
-The next elements are the coefficients of the unknowns,
-followed by the coefficients of the parameters, and finally the constant term.
-For instance, the following three constraints:
-
-@tex
-$$
-\hbox{$ \cases{ -i + m       &$= 0$\cr
-                -j + n       &$\geq 0$\cr
-                 j + i - k   &$\geq 0$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-    -i + m  = 0
-    -j + n >= 0
- i + j - k >= 0
-@end group
-@end example
-@end ifnottex
-
-@noindent would be represented by the following rows:
-
-@example
-@group
-# eq/in  i   j   k   m   n   cst
-    0    0  -1   0   1   0    0 
-    1   -1   0   0   0   1    0 
-    1    1   1  -1   0   0    0 
-@end group
-@end example
-
-@noindent To be able to provide different precision version (CLooG
-supports 32 bits, 64 bits and arbitrary precision through the GMP library),
-the @code{cloog_int_t} type depends on the configuration options (it may be
-@code{long int} for 32 bits version, @code{long long int} for 64 bits version,
-and @code{mpz_t} for multiple precision version).

-is a @code{clast_root}.
-It contains a placeholder for all the variable names that appear
-in the AST and a (list of) nested statement(s).
-
-@noindent
-A @code{clast_assignment} assigns the value given by
-the @code{clast_expr} @code{RHS} to a variable named @code{LHS}.
-
-@noindent
-A @code{clast_block} groups a list of statements into one statement.
-These statements are only generated if the @code{block} option is set,
-@pxref{Statement Block} and @ref{CloogOptions}.
-
-@noindent
-A @code{clast_user_stmt} represents a call to a statement specified
-by the user, @pxref{CloogStatement}.
-@code{substitutions} is a list of @code{clast_assignment} statements
-assigning an expression in terms of the scattering dimensions to
-each of the original iterators in the original order.
-The @code{LHS}s of these assignments are left blank (@code{NULL}).
-The @code{domain} is set to @code{NULL} if the @code{save_domains} option
-is not set.  Otherwise, it is set to the set
-of values for the scattering dimensions
-for which this instance of the user statement is executed.
-Note that unless the @code{noscalars} option has been set, the
-constant scattering dimensions may have been removed from this set.
-
-@noindent
-A @code{clast_for} represents a for loop, iterating @code{body} for each
-value of @code{iterator} between @code{LB} and @code{UB} in steps
-of size @code{stride}.
-The @code{domain} is set to @code{NULL} if the @code{save_domains} option is not
-set.  Otherwise, it is set to the set of values for the scattering dimensions
-for which a user statement is executed inside this @code{clast_for}.  Note that
-unless the @code{noscalars} option has been set, the constant scattering
-dimensions may have been removed from this set.
-
-@noindent
-A @code{clast_guard} represents the guarded execution of the @code{then}
-(list of) statement(s) by a conjunction of @code{n} (in)equalities.
-Each (in)equality is represented by a @code{clast_equation}.
-@example
-struct clast_equation @{
-    struct clast_expr *	LHS;
-    struct clast_expr *	RHS;
-    int			sign;
-@};
-@end example
-@noindent
-The condition expressed by a @code{clast_equation} is
-@code{LHS <= RHS}, @code{LHS == RHS} or @code{LHS >= RHS}
-depending on whether @code{sign} is less than zero, equal
-to zero, or greater than zero.
-
-The dynamic type of a @code{clast_stmt} can be determined
-using the macro @code{CLAST_STMT_IS_A(stmt,type)},
-where @code{stmt} is a pointer to a @code{clast_stmt}
-and @code{type} is one of @code{stmt_root}, @code{stmt_ass},
-@code{stmt_user}, @code{stmt_block}, @code{stmt_for} or
-@code{stmt_guard}.
-Users are allowed to define their own statement types by
-assigning the @code{op} field of the statements a pointer
-to a @code{clast_stmt_op} structure.
-@example
-struct clast_stmt_op @{
-    void (*free)(struct clast_stmt *);
-@};
-@end example
-@noindent
-The @code{free} field of this structure should point
-to a function that frees the user defined statement.
-
-@noindent
-A @code{clast_expr} can be an identifier, a term,
-a binary expression or a reduction.
-@example
-enum clast_expr_type @{
-    clast_expr_name,
-    clast_expr_term,
-    clast_expr_bin,
-    clast_expr_red
-@};
-struct clast_expr @{
-    enum clast_expr_type type;
-@};
-void free_clast_expr(struct clast_expr *e);
-@end example
-
-@noindent
-Identifiers are of subtype @code{clast_name}.
-@example
-struct clast_name @{
-    struct clast_expr	expr;
-    const char *	name;
-@};
-struct clast_name *new_clast_name(const char *name);
-void free_clast_name(struct clast_name *t);
-@end example
-@noindent
-The character string pointed to by @code{name} is
-assumed to be part of the @code{CloogNames} structure
-in the root of the clast as is therefore not copied.
-
-@noindent
-Terms are of type @code{clast_term}.
-@example
-struct clast_term @{
-    struct clast_expr   expr;
-    cloog_int_t         val;
-    struct clast_expr  *var;
-@};
-struct clast_term *new_clast_term(cloog_int_t c, struct clast_expr *v);
-void free_clast_term(struct clast_term *t);
-@end example
-@noindent
-If @code{var} is set to @code{NULL}, then the term represents
-the integer value @code{val}.  Otherwise, it represents
-the term @code{val * var}.
-@code{new_clast_term} simply copies the @code{v} pointer
-without copying the underlying @code{clast_expr}.
-@code{free_clast_term}, on the other hand, recursively frees
-@code{var}.
-
-@noindent
-Binary expressions are of type @code{clast_bin_type} and
-represent either the floor of a division (fdiv),
-the ceil of a division (cdiv), an exact division or
-the remainder of an fdiv.
-@example
-enum clast_bin_type @{ clast_bin_fdiv, clast_bin_cdiv, 
-                      clast_bin_div, clast_bin_mod @};
-struct clast_binary @{
-    struct clast_expr   expr;
-    enum clast_bin_type type;
-    struct clast_expr*  LHS;
-    cloog_int_t         RHS;
-@};
-struct clast_binary *new_clast_binary(enum clast_bin_type t, 
-                          struct clast_expr *lhs, cloog_int_t rhs);
-void free_clast_binary(struct clast_binary *b);
-@end example
-
-@noindent
-Reductions are of type @code{clast_reduction} and
-can represent either the sum, the minimum or the maximum
-of its elements.
-@example
-enum clast_red_type @{ clast_red_sum, clast_red_min, clast_red_max @};
-struct clast_reduction @{
-    struct clast_expr   expr;
-    enum clast_red_type type;
-    int                 n;
-    struct clast_expr*  elts[1];
-@};
-struct clast_reduction *new_clast_reduction(enum clast_red_type t,
-                                            int n);
-void free_clast_reduction(struct clast_reduction *r);

-@node Retrieving version information
-@section Retrieving version information
-CLooG provides static and dynamic version checks to assist on
-including a compatible version of the library.
-A static version check at compile time can be achieved by
-querying the version constants defined in @code{version.h}:
-
-@itemize @bullet
-@item @code{CLOOG_VERSION_MAJOR}
-@item @code{CLOOG_VERSION_MINOR}
-@item @code{CLOOG_VERSION_REVISION}
-@end itemize
-
-This way it is possible to ensure the included headers are of the
-correct version. It is still possible that the installed CLooG
-library version differs from the installed headers.
-In order to avoid this, a dynamic version check is provided with
-the functions:
-
-@example
-@group
-int cloog_version_major(void);
-int cloog_version_minor(void);
-int cloog_version_revision(void);
-@end group
-@end example
-
-By using both the static and the dynamic version check, it is possible
-to match CLooG's header version with the library's version.
-
-@node Example of Library Utilization
-@section Example of Library Utilization
-Here is a basic example showing how it is possible to use the CLooG library,
-assuming that a standard installation has been done.
-The following C program reads a CLooG input file on the standard input,
-then prints the solution on the standard output.
-Options are preselected to the default values of the CLooG software.
-This example is provided in the @code{example} directory of the
-CLooG distribution.

-/* example.c */
-# include <stdio.h>
-# include <cloog/cloog.h>

-
-  cloog_clast_free(root);
-  cloog_options_free(options) ;
-  cloog_state_free(state);
-  return 0;
-@}
-@end example

-@section Requirements
-
-CLooG can be used with one of two possible backends,
-one using isl and one using PolyLib.
-The isl library is included in the CLooG distribution,
-while the PolyLib library needs to be obtained separately.
-On the other hand, isl requires GMP, while PolyLib can be
-compiled with or without the use of GMP.
-The user therefore needs to install at least one of
-PolyLib or GMP.

-* GMP Library::
-@end menu
-
-
-@node PolyLib
-@subsection PolyLib (optional)
-To successfully install CLooG with the PolyLib backend,
-the user first needs to install PolyLib
-version 5.22.1 or above (default 64 bits version is satisfying
-as well as 32 bits or GMP multiple precision version).
-Polylib can be downloaded freely
-at @code{http://icps.u-strasbg.fr/PolyLib/} or
-@code{http://www.irisa.fr/polylib/}. Once downloaded and unpacked
-(e.g. using the @samp{tar -zxvf polylib-5.22.3.tar.gz} command),
-the user can compile
-it by typing the following commands on the PolyLib's root directory:
-
-@itemize @bullet
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-Alternatively, the latest development version can be obtained from the

-The PolyLib default installation is @code{/usr/local}. This directory may
-not be inside your library path. To fix the problem, the user should set
-@example
-export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
-@end example
-@noindent if your shell is, e.g., bash or
-@example
-setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/usr/local/lib
-@end example
-@noindent if your shell is, e.g., tcsh. Add the line to your .bashrc or .tcshrc (or
-whatever convenient file) to make this change permanent. Another solution
-is to ask PolyLib to install in the standard path by using the prefix
-option of the configure script:
-@samp{./configure --prefix=/usr}.
-
-CLooG makes intensive calls to polyhedral operations, and PolyLib
-functions do the job. Polylib is a free library written in C for the
-manipulation of polyhedra. The library is operating on objects like
-vectors, matrices, lattices, polyhedra, Z-polyhedra, unions of
-polyhedra and a lot of other intermediary structures. It provides
-functions for all the important operations on these structures.

-@node GMP Library
-@subsection GMP Library (optional)
-
-To be able to deal with insanely large coefficient, the user will need to
-install the GNU Multiple Precision Library (GMP for short) version 4.1.4
-or above. It can be freely downloaded from @code{http://www.swox.com/gmp}.
-Note that the isl backend currently requires GMP.
-The user can compile GMP by typing the following commands on the GMP root
-directory:
-
-@itemize @bullet
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-The GMP default installation is @code{/usr/local}, the same method to
-fix a library path problem applies as with PolyLib (@pxref{PolyLib}).
-
-If you want to use the PolyLib backend, then
-PolyLib has to be built using the GMP library by specifying the option
-@samp{--with-libgmp=PATH_TO_GMP} to the PolyLib configure script
-(where @code{PATH_TO_GMP} is @code{/usr/local} if you did not change the GMP
-installation directory). Then you have to set the convenient CLooG configure
-script options to build the GMP version (@pxref{Optional Features}).
-
-
-@node Basic Installation
-@section CLooG Basic Installation
-
-Once downloaded and unpacked
-(e.g. using the @samp{tar -zxvf cloog-@value{VERSION}.tar.gz} command),
-you can compile CLooG by typing the following commands on the CLooG's root
-directory:
-
-@itemize @bullet
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-Alternatively, the latest development version can be obtained from the
-git repository:
-@itemize @bullet
-@item @code{git clone git://repo.or.cz/cloog.git}
-@item @code{cd cloog}
-@item @code{./get_submodules.sh}
-@item @code{./autogen.sh}
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-Depending on which backend you want to use and where they
-are located, you may need to pass some
-options to the configure script, @pxref{Optional Features}.
-
-The program binaries and object files can be removed from the
-source code directory by typing @code{make clean}. To also remove the
-files that the @code{configure} script created (so you can compile the
-package for a different kind of computer) type @code{make distclean}.
-
-Both the CLooG software and library have been successfully compiled
-on the following systems:
-@itemize @bullet
-@item PC's under Linux, with the @code{gcc} compiler,
-@item PC's under Windows (Cygwin), with the @code{gcc} compiler,
-@item Sparc and UltraSparc Stations, with the @code{gcc} compiler.
-@end itemize
-
-@node Optional Features 
-@section Optional Features  
-The @code{configure} shell script attempts to guess correct values for
-various system-dependent variables and user options used during compilation.
-It uses those values to create the @code{Makefile}. Various user options
-are provided by the CLooG's configure script. They are summarized in the
-following list and may be printed by typing @code{./configure --help} in the
-CLooG top-level directory.
-
-@itemize @bullet
-@item By default, the installation directory is @code{/usr/local}:
-@code{make install} will install the package's files in
-@code{/usr/local/bin}, @code{/usr/local/lib} and @code{/usr/local/include}.
-The user can specify an installation prefix other than @code{/usr/local} by
-giving @code{configure} the option @code{--prefix=PATH}.
-
-@item By default, the isl backend will use the version of isl
-that is @code{bundled} together with CLooG.
-Using the @code{--with-isl} option of @code{configure}
-the user can specify that @code{no} isl,
-a previously installed (@code{system}) isl or a @code{build} isl
-should be used.
-In the latter case, the user should also specify the build location
-using @code{--with-isl-builddir=PATH}.
-In case of an installed isl,
-the installation location can be specified using the
-@code{--with-isl-prefix=PATH} and
-@code{--with-isl-exec-prefix=PATH} options of @code{configure}.
-
-@item By default, the PolyLib backend will use an installed
-(@code{system}) PolyLib, if any.
-The installation location can be specified using the
-@code{--with-polylib-prefix=PATH} and
-@code{--with-polylib-exec-prefix=PATH} options of @code{configure}.
-Using the @code{--with-polylib} option of @code{configure}
-the user can specify that @code{no} PolyLib or a @code{build} PolyLib
-should be used.
-In the latter case, the user should also specify the build location
-using @code{--with-polylib-builddir=PATH}.
-
-@item By default, the PolyLib backend of CLooG is built
-in 64bits version if such version of the
-PolyLib is found by @code{configure}. If the only existing version of the
-PolyLib is the 32bits or if the user give to @code{configure} the option
-@code{--with-bits=32}, the 32bits version of CLooG will be compiled. In the
-same way, the option @code{--with-bits=gmp} have to be used to build
-the multiple precision version.
-
-@item By default, @code{configure} will look for the GMP library
-(necessary to build the multiple precision version) in standard
-locations. If necessary, the user can specify the GMP path by giving
-@code{configure} the option @code{--with-gmp-prefix=PATH} and/or
-@code{--with-gmp-exec-prefix=PATH}.
-@end itemize
-
-@node Uninstallation 
-@section Uninstallation  
-The user can easily remove the CLooG software and library from his system
-by typing (as root if necessary) from the CLooG top-level directory
-@code{make uninstall}.
-
-@c %  **************************** DOCUMENTATION ******************************
-@node Documentation
-@chapter Documentation
-The CLooG distribution provides several documentation sources. First, the
-source code itself is as documented as possible. The code comments use a
-Doxygen-compatible presentation (something similar to what JavaDoc does for
-JAVA). The user may install Doxygen
-(see @code{http://www.stack.nl/~dimitri/doxygen}) to automatically
-generate a technical documentation by typing @code{make doc} or
-@code{doxygen ./autoconf/Doxyfile} at the CLooG top-level directory after
-running the configure script (@pxref{Installing}). Doxygen will generate
-documentation sources (in HTML, LaTeX and man) in the @code{doc/source}
-directory of the CLooG distribution.
-
-The Texinfo sources of the present document are also provided in the @code{doc}
-directory. You can build it in either DVI format (by typing
-@code{texi2dvi cloog.texi}) or PDF format
-(by typing @code{texi2pdf cloog.texi}) or HTML format
-(by typing @code{makeinfo --html cloog.texi}, using @code{--no-split}
-option to generate a single HTML file) or info format
-(by typing @code{makeinfo cloog.texi}).

-In this directory are presented various examples of how to use the CLooG
-library. For each case, you will need to edit the makefile file according to
-your system, in particular you will have to set where your CLooG library has
-been installed, and where are the CLooG header files. Don't forget to update
-your LD_LIBRARY_PATH environment variable to reach the CLooG library. If you
-performed the default installation of CLooG, the library is in /usr/local/lib
-thus you need to set LD_LIBRARY_PATH thanks to one of the following command:
-'setenv LD_LIBRARY_PATH /usr/local/lib' for tcsh-like shells, or
-'export LD_LIBRARY_PATH=/usr/local/lib' for bash-like shells.
-
-For any problem: <cedric.bastoul@inria.fr>.

-#   **-------------------------------------------------------------------**/
-
-
-This example program creates a simple CLooG-like loop generation program in a
-few lines. The input problem has to be given on standard input. We can test it
-for instance by typing 'more FILE.cloog | ./example' (or example.exe under
-Cygwin).

-This example creates a program converting a CLooG input file to a LoopGen input

- * these blocks but just to return a pointer to them and to increment the number
- * of active references. Each time a CloogBlock will be freed, we will decrement

-/* The CloogMatrix structure is equivalent to the PolyLib Matrix data structure
- * (see Wil93). This structure is devoted to represent a set of constraints.
- *
- * The whole matrix is stored in memory row after row at the p_Init address. p
- * is an array of pointers where p[i] points to the first element of the i^{th
- * row. NbRows and NbColumns are respectively the number of rows and columns of
- * the matrix. Each row corresponds to a constraint. The first element of each
- * row is an equality/inequality tag. The constraint is an equality p(x) = 0 if
- * the first element is 0, but it is an inequality p(x) \geq 0 if the first
- * element is 1. The next elements are the unknown coefficients, followed by
- * the parameter coefficients, then the constant term. For instance, the
- * following three constraints:
- *
- *     -i + m  = 0
- *     -j + n >= 0
- *  i + j - k >= 0
- *
- * would be represented by the following rows:
- *
- * # eq/in  i   j   k   m   n   cst
- *     0    0  -1   0   1   0    0
- *     1   -1   0   0   0   1    0
- *     1    1   1  -1   0   0    0
- *
- * To be able to provide different precision version (CLooG supports 32 bits,
- * 64 bits and arbitrary precision through the GMP library), the cloog_int_t
- * type depends on the configuration options (it may be long int for 32 bits
- * version, long long int for 64 bits version, and mpz_t for multiple precision

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-% "Chicago" BibTeX style, chicago.bst
-% ===================================
-%
-% BibTeX `chicago' style file for BibTeX version 0.99c, LaTeX version 2.09
-% Place it in a file called chicago.bst in the BibTeX search path.
-% You need to include chicago.sty as a \documentstyle option.
-% (Placing it in the same directory as the LaTeX document should also work.)
-% This "chicago" style is based on newapa.bst (American Psych. Assoc.)
-% found at ymir.claremont.edu.
-%
-%   Citation format: (author-last-name year)
-%             (author-last-name and author-last-name year)
-%             (author-last-name, author-last-name, and author-last-name year)
-%             (author-last-name et al. year)
-%             (author-last-name)
-%             author-last-name (year)
-%             (author-last-name and author-last-name)
-%             (author-last-name et al.)
-%             (year) or (year,year)
-%             year or year,year
-%
-%   Reference list ordering: alphabetical by author or whatever passes
-%    for author in the absence of one.
-%
-% This BibTeX style has support for abbreviated author lists and for
-%    year-only citations.  This is done by having the citations
-%    actually look like
-%
-%    \citeauthoryear{full-author-info}{abbrev-author-info}{year}
-%
-% The LaTeX style has to have the following (or similar)
-%
-%     \let\@internalcite\cite
-%     \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}
-%     \def\fullciteA{\def\citeauthoryear##1##2##3{##1}\@internalcite}
-%     \def\shortcite{\def\citeauthoryear##1##2##3{##2, ##3}\@internalcite}
-%     \def\shortciteA{\def\citeauthoryear##1##2##3{##2}\@internalcite}
-%     \def\citeyear{\def\citeauthoryear##1##2##3{##3}\@internalcite}
-%
-% These TeX macro definitions are found in chicago.sty. Additional
-% commands to manipulate different components of a citation can be defined
-% so that, for example, you can list author's names without parentheses
-% if using a citation as a noun or object in a sentence.
-%
-% This file was originally copied from newapa.bst at ymir.claremont.edu.
-%
-% Features of chicago.bst:
-% =======================
-%
-% - full names used in citations, but abbreviated citations are available
-%   (see above)
-% - if an entry has a "month", then the month and year are also printed
-%   as part of that bibitem.
-% - all conjunctions use "and" instead of "\&"
-% - major modification from Chicago Manual of Style (13th ed.) is that
-%   only the first author in a reference appears last name first-
-%   additional authors appear as J. Q. Public.
-% - pages are listed as "pp. xx-xx" in all entry types except
-%   article entries.
-% - book, inbook, and manual use "location: publisher" (or organization)
-%   for address and publisher. All other types list publishers separately.
-% - "pp." are used to identify page numbers for all entry types except
-%   articles.
-% - organization is used as a citation label if neither author nor editor
-%   is present (for manuals).
-% - "et al." is used for long author and editor lists, or when "others"
-%   is used.
-%
-% Modifications and bug fixes from newapa.bst:
-% ===========================================
-%
-%   - added month, year to bib entries if month is present
-%   - fixed bug with In proceedings, added necessary comma after title
-%   - all conjunctions changed to "and" from "\&"
-%   - fixed bug with author labels in my.full.label: "et al." now is
-%        generated when "others" is an author name
-%   - major modification from Chicago Manual of Style (13th ed.) is that
-%     only the first author in a reference appears last name first-
-%     additional authors appear as J. Q. Public.
-%   - pages are listed as "pp. xx-xx" in all entry types except
-%     article entries. Unnecessary (IMHO) "()" around page numbers
-%     were removed, and page numbers now don't end with a period.
-%   - created chicago.sty for use with this bibstyle (required).
-%   - fixed bugs in FUNCTION {format.vol.num.pages} for missing volume,
-%     number, and /or pages. Renamed to format.jour.vol.
-%   - fixed bug in formatting booktitles: additional period an error if
-%     book has a volume.
-%   - fixed bug: editors usually given redundant period before next clause
-%     (format.editors.dot) removed.
-%   - added label support for organizations, if both author and editor
-%     are missing (from alpha.bst). If organization is too long, then
-%     the key field is used for abbreviated citations.
-%   - In proceedings or books of several volumes, no comma was written
-%     between the "Volume x" and the page numbers (this was intentional
-%     in newapa.bst). Fixed.
-%   - Some journals may not have volumes/numbers, only month/year (eg.
-%     IEEE Computer). Fixed bug in article style that assumed volume/number
-%     was always present.
-%
-% Original documentation for newapa.sty:
-% =====================================
-%
-% This version was made by modifying the master file made by
-% Oren Patashnik (PATASHNIK@SCORE.STANFORD.EDU), and the 'named' BibTeX
-% style of Peter F. Patel-Schneider.
-%
-% Copyright (C) 1985, all rights reserved.
-% Copying of this file is authorized only if either
-% (1) you make absolutely no changes to your copy, including name, or
-% (2) if you do make changes, you name it something other than 'newapa.bst'.
-% There are undoubtably bugs in this style.  If you make bug fixes,
-% improvements, etc.  please let me know.  My e-mail address is:
-%    spencer@cgrg.ohio.state.edu or 71160.3141@compuserve.com
-%
-% This style was made from 'plain.bst', 'named.bst', and 'apalike.bst',
-% with lots of tweaking to make it look like APA style, along with tips
-% from Young Ryu and Brian Reiser's modifications of 'apalike.bst'.

-% bibliographies formatted according to the 13th Edition of the Chicago
-% Manual of Style.
-%
-% 'newapa.bst' was made from 'plain.bst', 'named.bst', and 'apalike.bst',
-% with lots of tweaking to make it look like APA style, along with tips
-% from Young Ryu and Brian Reiser's modifications of 'apalike.bst'.
-% newapa.sty formed the basis of this style, chicago.sty. Author-date
-% references in newapa.bst formed the basis for chicago.bst. Chicagoa.bst
-% supports annotations.
-%
-% Version 4 (August, 1992):
-% - fixed chicago.bst and chicagoa.bst to handle long author lists in
-%   sorting
-% - fixed chicago.bst and chicagoa.bst so that missing page numbers in
-%   ``article'' entries are handled correctly
-% - modified chicago.sty to format entries with 2nd and subsequent lines
-%   indented.
-%
-%   Citation format: (author-last-name year)
-%             (author-last-name and author-last-name year)
-%             (author-last-name et al. year)
-%             (author-last-name)
-%             author-last-name
-%             author-last-name (year)
-%             (author-last-name and author-last-name)
-%             (author-last-name et al.)
-%             (year) or (year,year)
-%             year or year,year
-%
-%   Reference list ordering: alphabetical by author or whatever passes
-%    for author in the absence of one.
-%
-% This BibTeX style has support for abbreviated author lists and for
-%    year-only citations.  This is done by having the citations
-%    actually look like
-%
-%    \citeauthoryear{full-author-info}{abbrev-author-info}{year}
-%
-% The LaTeX style has to have the following (or similar)
-%
-%     \let\@internalcite\cite
-%     \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}

-% This file implements citations for the ``chicago'' bibliography style.
-%  Place it in a file called chicago.sty in the TeX search path.
-%(Placing it in the same directory as the LaTeX document should also work.)
-%
-%    This file is a modification of the ``newapa'' LaTeX style,
-%    originally adapted by Steven Spencer from the ``apalike'' LaTeX style.
-%    It was originally modified by Stephen N. Spencer, with further
-%    modifications by Young U. Ryu.
-%
-% The ``chicago'' BibTeX bibliography style creates citations with labels:
-%       \citeauthoryear{author-info}{abbrev. author-info}{year}
-%
-% These labels are processed by the following LaTeX commands:
-%
-%  \cite{key}
-%    which produces citations with full author list and year.
-%    eg. (Brown 1978; Jarke, Turner, Stohl, et al. 1985)
-%  \citeNP{key}
-%    which produces citations with full author list and year, but without
-%    enclosing parentheses:
-%    eg. Brown 1978; Jarke, Turner and Stohl 1985
-%  \citeA{key}
-%    which produces citations with only the full author list.
-%    eg. (Brown; Jarke, Turner and Stohl)
-%  \citeANP{key}
-%    which produces citations with only the full author list, without
-%    parentheses eg. Brown; Jarke, Turner and Stohl
-%  \citeN{key}
-%    which produces citations with the full author list and year, but
-%    can be used as nouns in a sentence; no parentheses appear around
-%    the author names, but only around the year.
-%      eg. Shneiderman (1978) states that......
-%    \citeN should only be used for a single citation.
-%  \shortcite{key}
-%    which produces citations with abbreviated author list and year.
-%  \shortciteNP{key}
-%    which produces citations with abbreviated author list and year.
-%  \shortciteA{key}
-%    which produces only the abbreviated author list.
-%  \shortciteANP{key}
-%    which produces only the abbreviated author list.
-%  \shortciteN{key}
-%    which produces the abbreviated author list and year, with only the
-%    year in parentheses. Use with only one citation.
-%  \citeyear{key}
-%    which produces the year information only, within parentheses.
-%  \citeyearNP{key}
-%    which produces the year information only.
-%
-% Abbreviated author lists use the ``et al.'' construct.
-%
-% `NP' means `no parentheses'.

-\section{Simple Hull}\label{s:simple hull}
-
-It is sometimes useful to have a single
-basic set or basic relation that contains a given set or relation.
-For rational sets, the obvious choice would be to compute the
-(rational) convex hull.  For integer sets, the obvious choice
-would be the integer hull.
-However, {\tt isl} currently does not support an integer hull operation
-and even if it did, it would be fairly expensive to compute.
-The convex hull operation is supported, but it is also fairly
-expensive to compute given only an implicit representation.
-
-Usually, it is not required to compute the exact integer hull,
-and an overapproximation of this hull is sufficient.
-The ``simple hull'' of a set is such an overapproximation
-and it is defined as the (inclusion-wise) smallest basic set
-that is described by constraints that are translates of
-the constraints in the input set.
-This means that the simple hull is relatively cheap to compute
-and that the number of constraints in the simple hull is no
-larger than the number of constraints in the input.
-\begin{definition}[Simple Hull of a Set]
-The {\em simple hull} of a set
-$S = \bigcup_{1 \le i \le v} S_i$, with
-$$
-S : \Z^n \to 2^{\Z^d} : \vec s \mapsto
-S(\vec s) =
-\left\{\, \vec x \in \Z^d \mid \exists \vec z \in \Z^e :
-\bigvee_{1 \le i \le v}
-A_i \vec x + B_i \vec s + D_i \vec z + \vec c_i \geq \vec 0 \,\right\}
-$$
-is the set
-$$
-H : \Z^n \to 2^{\Z^d} : \vec s \mapsto
-S(\vec s) =
-\left\{\, \vec x \in \Z^d \mid \exists \vec z \in \Z^e :
-\bigwedge_{1 \le i \le v}
-A_i \vec x + B_i \vec s + D_i \vec z + \vec c_i + \vec K_i \geq \vec 0
-\,\right\}
-,
-$$
-with $\vec K_i$ the (component-wise) smallest non-negative integer vectors
-such that $S \subseteq H$.
-\end{definition}
-The $\vec K_i$ can be obtained by solving a number of
-LP problems, one for each element of each $\vec K_i$.
-If any LP problem is unbounded, then the corresponding constraint
-is dropped.
-
-\section{Parametric Integer Programming}
-
-\subsection{Introduction}\label{s:intro}
-
-Parametric integer programming \shortcite{Feautrier88parametric}
-is used to solve many problems within the context of the polyhedral model.
-Here, we are mainly interested in dependence analysis \shortcite{Fea91}
-and in computing a unique representation for existentially quantified
-variables.  The latter operation has been used for counting elements
-in sets involving such variables
-\shortcite{BouletRe98,Verdoolaege2005experiences} and lies at the core
-of the internal representation of {\tt isl}.
-
-Parametric integer programming was first implemented in \texttt{PipLib}.
-An alternative method for parametric integer programming
-was later implemented in {\tt barvinok} \cite{barvinok-0.22}.
-This method is not based on Feautrier's algorithm, but on rational
-generating functions \cite{Woods2003short} and was inspired by the
-``digging'' technique of \shortciteN{DeLoera2004Three} for solving
-non-parametric integer programming problems.
-
-In the following sections, we briefly recall the dual simplex
-method combined with Gomory cuts and describe some extensions
-and optimizations.  The main algorithm is applied to a matrix
-data structure known as a tableau.  In case of parametric problems,
-there are two tableaus, one for the main problem and one for
-the constraints on the parameters, known as the context tableau.
-The handling of the context tableau is described in \autoref{s:context}.
-
-\subsection{The Dual Simplex Method}
-
-Tableaus can be represented in several slightly different ways.
-In {\tt isl}, the dual simplex method uses the same representation
-as that used by its incremental LP solver based on the \emph{primal}
-simplex method.  The implementation of this LP solver is based
-on that of {\tt Simplify} \shortcite{Detlefs2005simplify}, which, in turn,
-was derived from the work of \shortciteN{Nelson1980phd}.
-In the original \shortcite{Nelson1980phd}, the tableau was implemented
-as a sparse matrix, but neither {\tt Simplify} nor the current
-implementation of {\tt isl} does so.
-
-Given some affine constraints on the variables,
-$A \vec x + \vec b \ge \vec 0$, the tableau represents the relationship
-between the variables $\vec x$ and non-negative variables
-$\vec y = A \vec x + \vec b$ corresponding to the constraints.
-The initial tableau contains $\begin{pmatrix}
-\vec b & A
-\end{pmatrix}$ and expresses the constraints $\vec y$ in the rows in terms
-of the variables $\vec x$ in the columns.  The main operation defined
-on a tableau exchanges a column and a row variable and is called a pivot.
-During this process, some coefficients may become rational.
-As in the \texttt{PipLib} implementation,
-{\tt isl} maintains a shared denominator per row.
-The sample value of a tableau is one where each column variable is assigned
-zero and each row variable is assigned the constant term of the row.
-This sample value represents a valid solution if each constraint variable
-is assigned a non-negative value, i.e., if the constant terms of
-rows corresponding to constraints are all non-negative.
-
-The dual simplex method starts from an initial sample value that
-may be invalid, but that is known to be (lexicographically) no
-greater than any solution, and gradually increments this sample value
-through pivoting until a valid solution is obtained.
-In particular, each pivot exchanges a row variable
-$r = -n + \sum_i a_i \, c_i$ with negative
-sample value $-n$ with a column variable $c_j$
-such that $a_j > 0$.  Since $c_j = (n + r - \sum_{i\ne j} a_i \, c_i)/a_j$,
-the new row variable will have a positive sample value $n$.
-If no such column can be found, then the problem is infeasible.
-By always choosing the column that leads to the (lexicographically)
-smallest increment in the variables $\vec x$,
-the first solution found is guaranteed to be the (lexicographically)
-minimal solution \cite{Feautrier88parametric}.
-In order to be able to determine the smallest increment, the tableau
-is (implicitly) extended with extra rows defining the original
-variables in terms of the column variables.
-If we assume that all variables are non-negative, then we know
-that the zero vector is no greater than the minimal solution and
-then the initial extended tableau looks as follows.
-$$
-\begin{tikzpicture}
-\matrix (m) [matrix of math nodes]
-{
-& {} & 1 & \vec c \\
-\vec x && |(top)| \vec 0 & I \\
-\vec r && \vec b & |(bottom)|A \\
-};
-\begin{pgfonlayer}{background}
-\node (core) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)] {};
-\end{pgfonlayer}
-\end{tikzpicture}
-$$
-Each column in this extended tableau is lexicographically positive
-and will remain so because of the column choice explained above.
-It is then clear that the value of $\vec x$ will increase in each step.
-Note that there is no need to store the extra rows explicitly.
-If a given $x_i$ is a column variable, then the corresponding row
-is the unit vector $e_i$.  If, on the other hand, it is a row variable,
-then the row already appears somewhere else in the tableau.
-
-In case of parametric problems, the sign of the constant term
-may depend on the parameters.  Each time the constant term of a constraint row
-changes, we therefore need to check whether the new term can attain
-negative and/or positive values over the current set of possible
-parameter values, i.e., the context.
-If all these terms can only attain non-negative values, the current
-state of the tableau represents a solution.  If one of the terms
-can only attain non-positive values and is not identically zero,
-the corresponding row can be pivoted.
-Otherwise, we pick one of the terms that can attain both positive
-and negative values and split the context into a part where
-it only attains non-negative values and a part where it only attains
-negative values.
-
-\subsection{Gomory Cuts}
-
-The solution found by the dual simplex method may have
-non-integral coordinates.  If so, some rational solutions
-(including the current sample value), can be cut off by
-applying a (parametric) Gomory cut.
-Let $r = b(\vec p) + \sp {\vec a} {\vec c}$ be the row
-corresponding to the first non-integral coordinate of $\vec x$,
-with $b(\vec p)$ the constant term, an affine expression in the
-parameters $\vec p$, i.e., $b(\vec p) = \sp {\vec f} {\vec p} + g$.
-Note that only row variables can attain
-non-integral values as the sample value of the column variables is zero.
-Consider the expression
-$b(\vec p) - \ceil{b(\vec p)} + \sp {\fract{\vec a}} {\vec c}$,
-with $\ceil\cdot$ the ceiling function and $\fract\cdot$ the
-fractional part.  This expression is negative at the sample value
-since $\vec c = \vec 0$ and $r = b(\vec p)$ is fractional, i.e.,
-$\ceil{b(\vec p)} > b(\vec p)$.  On the other hand, for each integral
-value of $r$ and $\vec c \ge 0$, the expression is non-negative
-because $b(\vec p) - \ceil{b(\vec p)} > -1$.
-Imposing this expression to be non-negative therefore does not
-invalidate any integral solutions, while it does cut away the current
-fractional sample value.  To be able to formulate this constraint,
-a new variable $q = \floor{-b(\vec p)} = - \ceil{b(\vec p)}$ is added
-to the context.  This integral variable is uniquely defined by the constraints
-$0 \le -d \, b(\vec p) - d \, q \le d - 1$, with $d$ the common
-denominator of $\vec f$ and $g$.  In practice, the variable
-$q' = \floor{\sp {\fract{-f}} {\vec p} + \fract{-g}}$ is used instead
-and the coefficients of the new constraint are adjusted accordingly.
-The sign of the constant term of this new constraint need not be determined
-as it is non-positive by construction.
-When several of these extra context variables are added, it is important
-to avoid adding duplicates.
-Recent versions of {\tt PipLib} also check for such duplicates.
-
-\subsection{Negative Unknowns and Maximization}
-
-There are two places in the above algorithm where the unknowns $\vec x$
-are assumed to be non-negative: the initial tableau starts from
-sample value $\vec x = \vec 0$ and $\vec c$ is assumed to be non-negative
-during the construction of Gomory cuts.
-To deal with negative unknowns, \shortciteN[Appendix A.2]{Fea91}
-proposed to use a ``big parameter'', say $M$, that is taken to be
-an arbitrarily large positive number.  Instead of looking for the
-lexicographically minimal value of $\vec x$, we search instead
-for the lexicographically minimal value of $\vec x' = \vec M + \vec x$.
-The sample value $\vec x' = \vec 0$ of the initial tableau then
-corresponds to $\vec x = -\vec M$, which is clearly not greater than
-any potential solution.  The sign of the constant term of a row
-is determined lexicographically, with the coefficient of $M$ considered
-first.  That is, if the coefficient of $M$ is not zero, then its sign
-is the sign of the entire term.  Otherwise, the sign is determined
-by the remaining affine expression in the parameters.
-If the original problem has a bounded optimum, then the final sample
-value will be of the form $\vec M + \vec v$ and the optimal value
-of the original problem is then $\vec v$.
-Maximization problems can be handled in a similar way by computing
-the minimum of $\vec M - \vec x$.
-
-When the optimum is unbounded, the optimal value computed for
-the original problem will involve the big parameter.
-In the original implementation of {\tt PipLib}, the big parameter could
-even appear in some of the extra variables $\vec q$ created during
-the application of a Gomory cut.  The final result could then contain
-implicit conditions on the big parameter through conditions on such
-$\vec q$ variables.  This problem was resolved in later versions
-of {\tt PipLib} by taking $M$ to be divisible by any positive number.
-The big parameter can then never appear in any $\vec q$ because
-$\fract {\alpha M } = 0$.  It should be noted, though, that an unbounded
-problem usually (but not always)
-indicates an incorrect formulation of the problem.
-
-The original version of {\tt PipLib} required the user to ``manually''
-add a big parameter, perform the reformulation and interpret the result
-\shortcite{Feautrier02}.  Recent versions allow the user to simply
-specify that the unknowns may be negative or that the maximum should
-be computed and then these transformations are performed internally.
-Although there are some application, e.g.,
-that of \shortciteN{Feautrier92multi},
-where it is useful to have explicit control over the big parameter,
-negative unknowns and maximization are by far the most common applications
-of the big parameter and we believe that the user should not be bothered
-with such implementation issues.
-The current version of {\tt isl} therefore does not
-provide any interface for specifying big parameters.  Instead, the user
-can specify whether a maximum needs to be computed and no assumptions
-are made on the sign of the unknowns.  Instead, the sign of the unknowns
-is checked internally and a big parameter is automatically introduced when
-needed.  For compatibility with {\tt PipLib}, the {\tt isl\_pip} tool
-does explicitly add non-negativity constraints on the unknowns unless
-the \verb+Urs_unknowns+ option is specified.
-Currently, there is also no way in {\tt isl} of expressing a big
-parameter in the output.  Even though
-{\tt isl} makes the same divisibility assumption on the big parameter
-as recent versions of {\tt PipLib}, it will therefore eventually
-produce an error if the problem turns out to be unbounded.
-
-\subsection{Preprocessing}
-
-In this section, we describe some transformations that are
-or can be applied in advance to reduce the running time
-of the actual dual simplex method with Gomory cuts.
-
-\subsubsection{Feasibility Check and Detection of Equalities}
-
-Experience with the original {\tt PipLib} has shown that Gomory cuts
-do not perform very well on problems that are (non-obviously) empty,
-i.e., problems with rational solutions, but no integer solutions.
-In {\tt isl}, we therefore first perform a feasibility check on
-the original problem considered as a non-parametric problem
-over the combined space of unknowns and parameters.
-In fact, we do not simply check the feasibility, but we also
-check for implicit equalities among the integer points by computing
-the integer affine hull.  The algorithm used is the same as that
-described in \autoref{s:GBR} below.
-Computing the affine hull is fairly expensive, but it can
-bring huge benefits if any equalities can be found or if the problem
-turns out to be empty.
-
-\subsubsection{Constraint Simplification}
-
-If the coefficients of the unknown and parameters in a constraint
-have a common factor, then this factor should be removed, possibly
-rounding down the constant term.  For example, the constraint
-$2 x - 5 \ge 0$ should be simplified to $x - 3 \ge 0$.
-{\tt isl} performs such simplifications on all sets and relations.
-Recent versions of {\tt PipLib} also perform this simplification
-on the input.
-
-\subsubsection{Exploiting Equalities}\label{s:equalities}
-
-If there are any (explicit) equalities in the input description,
-{\tt PipLib} converts each into a pair of inequalities.
-It is also possible to write $r$ equalities as $r+1$ inequalities
-\shortcite{Feautrier02}, but it is even better to \emph{exploit} the
-equalities to reduce the dimensionality of the problem.
-Given an equality involving at least one unknown, we pivot
-the row corresponding to the equality with the column corresponding
-to the last unknown with non-zero coefficient.  The new column variable
-can then be removed completely because it is identically zero,
-thereby reducing the dimensionality of the problem by one.
-The last unknown is chosen to ensure that the columns of the initial
-tableau remain lexicographically positive.  In particular, if
-the equality is of the form $b + \sum_{i \le j} a_i \, x_i = 0$ with
-$a_j \ne 0$, then the (implicit) top rows of the initial tableau
-are changed as follows
-$$
-\begin{tikzpicture}
-\matrix [matrix of math nodes]
-{
- & {} & |(top)| 0 & I_1 & |(j)| &  \\
-j && 0 & & 1 & \\
-  && 0 & & & |(bottom)|I_2 \\
-};
-\node[overlay,above=2mm of j,anchor=south]{j};
-\begin{pgfonlayer}{background}
-\node (m) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)] {};
-\end{pgfonlayer}
-\begin{scope}[xshift=4cm]
-\matrix [matrix of math nodes]
-{
- & {} & |(top)| 0 & I_1 &  \\
-j && |(left)| -b/a_j & -a_i/a_j & \\
-  && 0 & & |(bottom)|I_2 \\
-};
-\begin{pgfonlayer}{background}
-\node (m2) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)(left)] {};
-\end{pgfonlayer}
-\end{scope}
- \draw [shorten >=7mm,-to,thick,decorate,
-        decoration={snake,amplitude=.4mm,segment length=2mm,
-                    pre=moveto,pre length=5mm,post length=8mm}]
-   (m) -- (m2);
-\end{tikzpicture}
-$$
-Currently, {\tt isl} also eliminates equalities involving only parameters
-in a similar way, provided at least one of the coefficients is equal to one.
-The application of parameter compression (see below)
-would obviate the need for removing parametric equalities.
-
-\subsubsection{Offline Symmetry Detection}\label{s:offline}
-
-Some problems, notably those of \shortciteN{Bygde2010licentiate},
-have a collection of constraints, say
-$b_i(\vec p) + \sp {\vec a} {\vec x} \ge 0$,
-that only differ in their (parametric) constant terms.
-These constant terms will be non-negative on different parts
-of the context and this context may have to be split for each
-of the constraints.  In the worst case, the basic algorithm may
-have to consider all possible orderings of the constant terms.
-Instead, {\tt isl} introduces a new parameter, say $u$, and
-replaces the collection of constraints by the single
-constraint $u + \sp {\vec a} {\vec x} \ge 0$ along with
-context constraints $u \le b_i(\vec p)$.
-Any solution to the new system is also a solution
-to the original system since
-$\sp {\vec a} {\vec x} \ge -u \ge -b_i(\vec p)$.
-Conversely, $m = \min_i b_i(\vec p)$ satisfies the constraints
-on $u$ and therefore extends a solution to the new system.
-It can also be plugged into a new solution.
-See \autoref{s:post} for how this substitution is currently performed
-in {\tt isl}.
-The method described in this section can only detect symmetries
-that are explicitly available in the input.
-See \autoref{s:online} for the detection
-and exploitation of symmetries that appear during the course of
-the dual simplex method.
-
-\subsubsection{Parameter Compression}\label{s:compression}
-
-It may in some cases be apparent from the equalities in the problem
-description that there can only be a solution for a sublattice
-of the parameters.  In such cases ``parameter compression''
-\shortcite{Meister2004PhD,Meister2008} can be used to replace
-the parameters by alternative ``dense'' parameters.
-For example, if there is a constraint $2x = n$, then the system
-will only have solutions for even values of $n$ and $n$ can be replaced
-by $2n'$.  Similarly, the parameters $n$ and $m$ in a system with
-the constraint $2n = 3m$ can be replaced by a single parameter $n'$
-with $n=3n'$ and $m=2n'$.
-It is also possible to perform a similar compression on the unknowns,
-but it would be more complicated as the compression would have to
-preserve the lexicographical order.  Moreover, due to our handling
-of equalities described above there should be
-no need for such variable compression.
-Although parameter compression has been implemented in {\tt isl},
-it is currently not yet used during parametric integer programming.
-
-\subsection{Postprocessing}\label{s:post}
-
-The output of {\tt PipLib} is a quast (quasi-affine selection tree).
-Each internal node in this tree corresponds to a split of the context
-based on a parametric constant term in the main tableau with indeterminate
-sign.  Each of these nodes may introduce extra variables in the context
-corresponding to integer divisions.  Each leaf of the tree prescribes
-the solution in that part of the context that satisfies all the conditions
-on the path leading to the leaf.
-Such a quast is a very economical way of representing the solution, but
-it would not be suitable as the (only) internal representation of
-sets and relations in {\tt isl}.  Instead, {\tt isl} represents
-the constraints of a set or relation in disjunctive normal form.
-The result of a parametric integer programming problem is then also
-converted to this internal representation.  Unfortunately, the conversion
-to disjunctive normal form can lead to an explosion of the size
-of the representation.
-In some cases, this overhead would have to be paid anyway in subsequent
-operations, but in other cases, especially for outside users that just
-want to solve parametric integer programming problems, we would like
-to avoid this overhead in future.  That is, we are planning on introducing
-quasts or a related representation as one of several possible internal
-representations and on allowing the output of {\tt isl\_pip} to optionally
-be printed as a quast.
-
-Currently, {\tt isl} also does not have an internal representation
-for expressions such as $\min_i b_i(\vec p)$ from the offline
-symmetry detection of \autoref{s:offline}.
-Assume that one of these expressions has $n$ bounds $b_i(\vec p)$.
-If the expression
-does not appear in the affine expression describing the solution,
-but only in the constraints, and if moreover, the expression
-only appears with a positive coefficient, i.e.,
-$\min_i b_i(\vec p) \ge f_j(\vec p)$, then each of these constraints
-can simply be reduplicated $n$ times, once for each of the bounds.
-Otherwise, a conversion to disjunctive normal form
-leads to $n$ cases, each described as $u = b_i(\vec p)$ with constraints
-$b_i(\vec p) \le b_j(\vec p)$ for $j > i$
-and
-$b_i(\vec p)  < b_j(\vec p)$ for $j < i$.
-Note that even though this conversion leads to a size increase
-by a factor of $n$, not detecting the symmetry could lead to
-an increase by a factor of $n!$ if all possible orderings end up being
-considered.
-
-\subsection{Context Tableau}\label{s:context}
-
-The main operation that a context tableau needs to provide is a test
-on the sign of an affine expression over the elements of the context.
-This sign can be determined by solving two integer linear feasibility
-problems, one with a constraint added to the context that enforces
-the expression to be non-negative and one where the expression is
-negative.  As already mentioned by \shortciteN{Feautrier88parametric},
-any integer linear feasibility solver could be used, but the {\tt PipLib}
-implementation uses a recursive call to the dual simplex with Gomory
-cuts algorithm to determine the feasibility of a context.
-In {\tt isl}, two ways of handling the context have been implemented,
-one that performs the recursive call and one, used by default, that
-uses generalized basis reduction.
-We start with some optimizations that are shared between the two
-implementations and then discuss additional details of each of them.
-
-\subsubsection{Maintaining Witnesses}\label{s:witness}
-
-A common feature of both integer linear feasibility solvers is that
-they will not only say whether a set is empty or not, but if the set
-is non-empty, they will also provide a \emph{witness} for this result,
-i.e., a point that belongs to the set.  By maintaining a list of such
-witnesses, we can avoid many feasibility tests during the determination
-of the signs of affine expressions.  In particular, if the expression
-evaluates to a positive number on some of these points and to a negative
-number on some others, then no feasibility test needs to be performed.
-If all the evaluations are non-negative, we only need to check for the
-possibility of a negative value and similarly in case of all
-non-positive evaluations.  Finally, in the rare case that all points
-evaluate to zero or at the start, when no points have been collected yet,
-one or two feasibility tests need to be performed depending on the result
-of the first test.
-
-When a new constraint is added to the context, the points that
-violate the constraint are temporarily removed.  They are reconsidered
-when we backtrack over the addition of the constraint, as they will
-satisfy the negation of the constraint.  It is only when we backtrack
-over the addition of the points that they are finally removed completely.
-When an extra integer division is added to the context,
-the new coordinates of the
-witnesses can easily be computed by evaluating the integer division.
-The idea of keeping track of witnesses was first used in {\tt barvinok}.
-
-\subsubsection{Choice of Constant Term on which to Split}
-
-Recall that if there are no rows with a non-positive constant term,
-but there are rows with an indeterminate sign, then the context
-needs to be split along the constant term of one of these rows.
-If there is more than one such row, then we need to choose which row
-to split on first.  {\tt PipLib} uses a heuristic based on the (absolute)
-sizes of the coefficients.  In particular, it takes the largest coefficient
-of each row and then selects the row where this largest coefficient is smaller
-than those of the other rows.
-
-In {\tt isl}, we take that row for which non-negativity of its constant
-term implies non-negativity of as many of the constant terms of the other
-rows as possible.  The intuition behind this heuristic is that on the
-positive side, we will have fewer negative and indeterminate signs,
-while on the negative side, we need to perform a pivot, which may
-affect any number of rows meaning that the effect on the signs
-is difficult to predict.  This heuristic is of course much more
-expensive to evaluate than the heuristic used by {\tt PipLib}.
-More extensive tests are needed to evaluate whether the heuristic is worthwhile.
-
-\subsubsection{Dual Simplex + Gomory Cuts}
-
-When a new constraint is added to the context, the first steps
-of the dual simplex method applied to this new context will be the same
-or at least very similar to those taken on the original context, i.e.,
-before the constraint was added.  In {\tt isl}, we therefore apply
-the dual simplex method incrementally on the context and backtrack
-to a previous state when a constraint is removed again.
-An initial implementation that was never made public would also
-keep the Gomory cuts, but the current implementation backtracks
-to before the point where Gomory cuts are added before adding
-an extra constraint to the context.
-Keeping the Gomory cuts has the advantage that the sample value
-is always an integer point and that this point may also satisfy
-the new constraint.  However, due to the technique of maintaining
-witnesses explained above,
-we would not perform a feasibility test in such cases and then
-the previously added cuts may be redundant, possibly resulting
-in an accumulation of a large number of cuts.
-
-If the parameters may be negative, then the same big parameter trick
-used in the main tableau is applied to the context.  This big parameter
-is of course unrelated to the big parameter from the main tableau.
-Note that it is not a requirement for this parameter to be ``big'',
-but it does allow for some code reuse in {\tt isl}.
-In {\tt PipLib}, the extra parameter is not ``big'', but this may be because
-the big parameter of the main tableau also appears
-in the context tableau.
-
-Finally, it was reported by \shortciteN{Galea2009personal}, who
-worked on a parametric integer programming implementation
-in {\tt PPL} \shortcite{PPL},
-that it is beneficial to add cuts for \emph{all} rational coordinates
-in the context tableau.  Based on this report,
-the initial {\tt isl} implementation was adapted accordingly.
-
-\subsubsection{Generalized Basis Reduction}\label{s:GBR}
-
-The default algorithm used in {\tt isl} for feasibility checking
-is generalized basis reduction \shortcite{Cook1991implementation}.
-This algorithm is also used in the {\tt barvinok} implementation.
-The algorithm is fairly robust, but it has some overhead.
-We therefore try to avoid calling the algorithm in easy cases.
-In particular, we incrementally keep track of points for which
-the entire unit hypercube positioned at that point lies in the context.
-This set is described by translates of the constraints of the context
-and if (rationally) non-empty, any rational point
-in the set can be rounded up to yield an integer point in the context.
-
-A restriction of the algorithm is that it only works on bounded sets.
-The affine hull of the recession cone therefore needs to be projected
-out first.  As soon as the algorithm is invoked, we then also
-incrementally keep track of this recession cone.  The reduced basis
-found by one call of the algorithm is also reused as initial basis
-for the next call.
-
-Some problems lead to the
-introduction of many integer divisions.  Within a given context,
-some of these integer divisions may be equal to each other, even
-if the expressions are not identical, or they may be equal to some
-affine combination of other variables.
-To detect such cases, we compute the affine hull of the context
-each time a new integer division is added.  The algorithm used
-for computing this affine hull is that of \shortciteN{Karr1976affine},
-while the points used in this algorithm are obtained by performing
-integer feasibility checks on that part of the context outside
-the current approximation of the affine hull.
-The list of witnesses is used to construct an initial approximation
-of the hull, while any extra points found during the construction
-of the hull is added to this list.
-Any equality found in this way that expresses an integer division
-as an \emph{integer} affine combination of other variables is
-propagated to the main tableau, where it is used to eliminate that
-integer division.
-
-\subsection{Experiments}
-
-\autoref{t:comparison} compares the execution times of {\tt isl}
-(with both types of context tableau)
-on some more difficult instances to those of other tools,
-run on an Intel Xeon W3520 @ 2.66GHz.
-Easier problems such as the
-test cases distributed with {\tt Pip\-Lib} can be solved so quickly
-that we would only be measuring overhead such as input/output and conversions
-and not the running time of the actual algorithm.
-We compare the following versions:
-{\tt piplib-1.4.0-5-g0132fd9},
-{\tt barvinok-0.32.1-73-gc5d7751},
-{\tt isl-0.05.1-82-g3a37260}
-and {\tt PPL} version 0.11.2.
-
-The first test case is the following dependence analysis problem
-originating from the Phideo project \shortcite{Verhaegh1995PhD}
-that was communicated to us by Bart Kienhuis:
-\begin{lstlisting}[flexiblecolumns=true,breaklines=true]{}
-lexmax { [j1,j2] -> [i1,i2,i3,i4,i5,i6,i7,i8,i9,i10] : 1 <= i1,j1 <= 8 and 1 <= i2,i3,i4,i5,i6,i7,i8,i9,i10 <= 2 and 1 <= j2 <= 128 and i1-1 = j1-1 and i2-1+2*i3-2+4*i4-4+8*i5-8+16*i6-16+32*i7-32+64*i8-64+128*i9-128+256*i10-256=3*j2-3+66 };
-\end{lstlisting}
-This problem was the main inspiration
-for some of the optimizations in \autoref{s:GBR}.
-The second group of test cases are projections used during counting.
-The first nine of these come from \shortciteN{Seghir2006minimizing}.
-The remaining two come from \shortciteN{Verdoolaege2005experiences} and
-were used to drive the first, Gomory cuts based, implementation
-in {\tt isl}.
-The third and final group of test cases are borrowed from
-\shortciteN{Bygde2010licentiate} and inspired the offline symmetry detection
-of \autoref{s:offline}.  Without symmetry detection, the running times
-are 11s and 5.9s.
-All running times of {\tt barvinok} and {\tt isl} include a conversion
-to disjunctive normal form.  Without this conversion, the final two
-cases can be solved in 0.07s and 0.21s.
-The {\tt PipLib} implementation has some fixed limits and will
-sometimes report the problem to be too complex (TC), while on some other
-problems it will run out of memory (OOM).
-The {\tt barvinok} implementation does not support problems
-with a non-trivial lineality space (line) nor maximization problems (max).
-The Gomory cuts based {\tt isl} implementation was terminated after 1000
-minutes on the first problem.  The gbr version introduces some
-overhead on some of the easier problems, but is overall the clear winner.

-\subsection{Online Symmetry Detection}\label{s:online}
-
-Manual experiments on small instances of the problems of
-\shortciteN{Bygde2010licentiate} and an analysis of the results
-by the approximate MPA method developed by \shortciteN{Bygde2010licentiate}
-have revealed that these problems contain many more symmetries
-than can be detected using the offline method of \autoref{s:offline}.
-In this section, we present an online detection mechanism that has
-not been implemented yet, but that has shown promising results
-in manual applications.
-
-Let us first consider what happens when we do not perform offline
-symmetry detection.  At some point, one of the
-$b_i(\vec p) + \sp {\vec a} {\vec x} \ge 0$ constraints,
-say the $j$th constraint, appears as a column
-variable, say $c_1$, while the other constraints are represented
-as rows of the form $b_i(\vec p) - b_j(\vec p) + c$.
-The context is then split according to the relative order of
-$b_j(\vec p)$ and one of the remaining $b_i(\vec p)$.
-The offline method avoids this split by replacing all $b_i(\vec p)$
-by a single newly introduced parameter that represents the minimum
-of these $b_i(\vec p)$.
-In the online method the split is similarly avoided by the introduction
-of a new parameter.  In particular, a new parameter is introduced
-that represents
-$\left| b_j(\vec p) - b_i(\vec p) \right|_+ =
-\max(b_j(\vec p) - b_i(\vec p), 0)$.
-
-In general, let $r = b(\vec p) + \sp {\vec a} {\vec c}$ be a row
-of the tableau such that the sign of $b(\vec p)$ is indeterminate
-and such that exactly one of the elements of $\vec a$ is a $1$,
-while all remaining elements are non-positive.
-That is, $r = b(\vec p) + c_j - f$ with $f = -\sum_{i\ne j} a_i c_i \ge 0$.
-We introduce a new parameter $t$ with
-context constraints $t \ge -b(\vec p)$ and $t \ge 0$ and replace
-the column variable $c_j$ by $c' + t$.  The row $r$ is now equal
-to $b(\vec p) + t + c' - f$.  The constant term of this row is always
-non-negative because any negative value of $b(\vec p)$ is compensated
-by $t \ge -b(\vec p)$ while and non-negative value remains non-negative
-because $t \ge 0$.
-
-We need to show that this transformation does not eliminate any valid
-solutions and that it does not introduce any spurious solutions.
-Given a valid solution for the original problem, we need to find
-a non-negative value of $c'$ satisfying the constraints.
-If $b(\vec p) \ge 0$, we can take $t = 0$ so that
-$c' = c_j - t = c_j \ge 0$.
-If $b(\vec p) < 0$, we can take $t = -b(\vec p)$.
-Since $r = b(\vec p) + c_j - f \ge 0$ and $f \ge 0$, we have 
-$c' = c_j + b(\vec p) \ge 0$.
-Note that these choices amount to plugging in
-$t = \left|-b(\vec p)\right|_+ = \max(-b(\vec p), 0)$.
-Conversely, given a solution to the new problem, we need to find
-a non-negative value of $c_j$, but this is easy since $c_j = c' + t$
-and both of these are non-negative.
-
-Plugging in $t = \max(-b(\vec p), 0)$ can be performed as in
-\autoref{s:post}, but, as in the case of offline symmetry detection,
-it may be better to provide a direct representation for such
-expressions in the internal representation of sets and relations
-or at least in a quast-like output format.

-\section{Transitive Closure}
-
-\subsection{Introduction}
-
-\begin{definition}[Power of a Relation]
-Let $R \in \Z^n \to 2^{\Z^{d+d}}$ be a relation and
-$k \in \Z_{\ge 1}$
-a positive number, then power $k$ of relation $R$ is defined as
-\begin{equation}
-\label{eq:transitive:power}
-R^k \coloneqq
-\begin{cases}
-R & \text{if $k = 1$}
-\\
-R \circ R^{k-1} & \text{if $k \ge 2$}
-.
-\end{cases}
-\end{equation}
-\end{definition}
-
-\begin{definition}[Transitive Closure of a Relation]
-Let $R \in \Z^n \to 2^{\Z^{d+d}}$ be a relation,
-then the transitive closure $R^+$ of $R$ is the union
-of all positive powers of $R$,
-$$
-R^+ \coloneqq \bigcup_{k \ge 1} R^k
-.
-$$
-\end{definition}
-Alternatively, the transitive closure may be defined
-inductively as
-\begin{equation}
-\label{eq:transitive:inductive}
-R^+ \coloneqq R \cup \left(R \circ R^+\right)
-.
-\end{equation}
-
-Since the transitive closure of a polyhedral relation
-may no longer be a polyhedral relation \shortcite{Kelly1996closure},
-we can, in the general case, only compute an approximation
-of the transitive closure.
-Whereas \shortciteN{Kelly1996closure} compute underapproximations,
-we, like \shortciteN{Beletska2009}, compute overapproximations.
-That is, given a relation $R$, we will compute a relation $T$
-such that $R^+ \subseteq T$.  Of course, we want this approximation
-to be as close as possible to the actual transitive closure
-$R^+$ and we want to detect the cases where the approximation is
-exact, i.e., where $T = R^+$.
-
-For computing an approximation of the transitive closure of $R$,
-we follow the same general strategy as \shortciteN{Beletska2009}
-and first compute an approximation of $R^k$ for $k \ge 1$ and then project
-out the parameter $k$ from the resulting relation.
-
-\begin{example}
-As a trivial example, consider the relation
-$R = \{\, x \to x + 1 \,\}$.  The $k$th power of this map
-for arbitrary $k$ is
-$$
-R^k = k \mapsto \{\, x \to x + k \mid k \ge 1 \,\}
-.
-$$
-The transitive closure is then
-$$
-\begin{aligned}
-R^+ & = \{\, x \to y \mid \exists k \in \Z_{\ge 1} : y = x + k \,\}
-\\
-& = \{\, x \to y \mid y \ge x + 1 \,\}
-.
-\end{aligned}
-$$
-\end{example}
-
-\subsection{Computing an Approximation of $R^k$}
-\label{s:power}
-
-There are some special cases where the computation of $R^k$ is very easy.
-One such case is that where $R$ does not compose with itself,
-i.e., $R \circ R = \emptyset$ or $\domain R \cap \range R = \emptyset$.
-In this case, $R^k$ is only non-empty for $k=1$ where it is equal
-to $R$ itself.
-
-In general, it is impossible to construct a closed form
-of $R^k$ as a polyhedral relation.
-We will therefore need to make some approximations.
-As a first approximations, we will consider each of the basic
-relations in $R$ as simply adding one or more offsets to a domain element
-to arrive at an image element and ignore the fact that some of these
-offsets may only be applied to some of the domain elements.
-That is, we will only consider the difference set $\Delta\,R$ of the relation.
-In particular, we will first construct a collection $P$ of paths
-that move through
-a total of $k$ offsets and then intersect domain and range of this
-collection with those of $R$.
-That is, 
-\begin{equation}
-\label{eq:transitive:approx}
-K = P \cap \left(\domain R \to \range R\right)
-,
-\end{equation}
-with
-\begin{equation}
-\label{eq:transitive:path}
-P = \vec s \mapsto \{\, \vec x \to \vec y \mid
-\exists k_i \in \Z_{\ge 0}, \vec\delta_i \in k_i \, \Delta_i(\vec s) :
-\vec y = \vec x + \sum_i \vec\delta_i
-\wedge
-\sum_i k_i = k > 0
-\,\}
-\end{equation}
-and with $\Delta_i$ the basic sets that compose
-the difference set $\Delta\,R$.
-Note that the number of basic sets $\Delta_i$ need not be
-the same as the number of basic relations in $R$.
-Also note that since addition is commutative, it does not
-matter in which order we add the offsets and so we are allowed
-to group them as we did in \eqref{eq:transitive:path}.
-
-If all the $\Delta_i$s are singleton sets
-$\Delta_i = \{\, \vec \delta_i \,\}$ with $\vec \delta_i \in \Z^d$,
-then \eqref{eq:transitive:path} simplifies to
-\begin{equation}
-\label{eq:transitive:singleton}
-P = \{\, \vec x \to \vec y \mid
-\exists k_i \in \Z_{\ge 0} :
-\vec y = \vec x + \sum_i k_i \, \vec \delta_i
-\wedge
-\sum_i k_i = k > 0
-\,\}
-\end{equation}
-and then the approximation computed in \eqref{eq:transitive:approx}
-is essentially the same as that of \shortciteN{Beletska2009}.
-If some of the $\Delta_i$s are not singleton sets or if
-some of $\vec \delta_i$s are parametric, then we need
-to resort to further approximations.
-
-To ease both the exposition and the implementation, we will for
-the remainder of this section work with extended offsets
-$\Delta_i' = \Delta_i \times \{\, 1 \,\}$.
-That is, each offset is extended with an extra coordinate that is
-set equal to one.  The paths constructed by summing such extended
-offsets have the length encoded as the difference of their
-final coordinates.  The path $P'$ can then be decomposed into
-paths $P_i'$, one for each $\Delta_i$,
-\begin{equation}
-\label{eq:transitive:decompose}
-P' = \left(
-(P_m' \cup \identity) \circ \cdots \circ
-(P_2' \cup \identity) \circ
-(P_1' \cup \identity)
-\right) \cap
-\{\,
-\vec x' \to \vec y' \mid y_{d+1} - x_{d+1} = k > 0
-\,\}
-,
-\end{equation}
-with
-$$
-P_i' = \vec s \mapsto \{\, \vec x' \to \vec y' \mid
-\exists k \in \Z_{\ge 1}, \vec \delta \in k \, \Delta_i'(\vec s) :
-\vec y' = \vec x' + \vec \delta
-\,\}
-.
-$$
-Note that each $P_i'$ contains paths of length at least one.
-We therefore need to take the union with the identity relation
-when composing the $P_i'$s to allow for paths that do not contain
-any offsets from one or more $\Delta_i'$.
-The path that consists of only identity relations is removed
-by imposing the constraint $y_{d+1} - x_{d+1} > 0$.
-Taking the union with the identity relation means that
-that the relations we compose in \eqref{eq:transitive:decompose}
-each consist of two basic relations.  If there are $m$
-disjuncts in the input relation, then a direct application
-of the composition operation may therefore result in a relation
-with $2^m$ disjuncts, which is prohibitively expensive.
-It is therefore crucial to apply coalescing (\autoref{s:coalescing})
-after each composition.
-
-Let us now consider how to compute an overapproximation of $P_i'$.
-Those that correspond to singleton $\Delta_i$s are grouped together
-and handled as in \eqref{eq:transitive:singleton}.
-Note that this is just an optimization.  The procedure described
-below would produce results that are at least as accurate.
-For simplicity, we first assume that no constraint in $\Delta_i'$
-involves any existentially quantified variables.
-We will return to existentially quantified variables at the end
-of this section.
-Without existentially quantified variables, we can classify
-the constraints of $\Delta_i'$ as follows
-\begin{enumerate}
-\item non-parametric constraints
-\begin{equation}
-\label{eq:transitive:non-parametric}
-A_1 \vec x + \vec c_1 \geq \vec 0
-\end{equation}
-\item purely parametric constraints
-\begin{equation}
-\label{eq:transitive:parametric}
-B_2 \vec s + \vec c_2 \geq \vec 0
-\end{equation}
-\item negative mixed constraints
-\begin{equation}
-\label{eq:transitive:mixed}
-A_3 \vec x + B_3 \vec s + \vec c_3 \geq \vec 0
-\end{equation}
-such that for each row $j$ and for all $\vec s$,
-$$
-\Delta_i'(\vec s) \cap
-\{\, \vec \delta' \mid B_{3,j} \vec s + c_{3,j} > 0 \,\}
-= \emptyset
-$$
-\item positive mixed constraints
-$$
-A_4 \vec x + B_4 \vec s + \vec c_4 \geq \vec 0
-$$
-such that for each row $j$, there is at least one $\vec s$ such that
-$$
-\Delta_i'(\vec s) \cap
-\{\, \vec \delta' \mid B_{4,j} \vec s + c_{4,j} > 0 \,\}
-\ne \emptyset
-$$
-\end{enumerate}
-We will use the following approximation $Q_i$ for $P_i'$:
-\begin{equation}
-\label{eq:transitive:Q}
-\begin{aligned}
-Q_i = \vec s \mapsto
-\{\,
-\vec x' \to \vec y'
-\mid {} & \exists k \in \Z_{\ge 1}, \vec f \in \Z^d :
-\vec y' = \vec x' + (\vec f, k)
-\wedge {}
-\\
-&
-A_1 \vec f + k \vec c_1 \geq \vec 0
-\wedge
-B_2 \vec s + \vec c_2 \geq \vec 0
-\wedge
-A_3 \vec f + B_3 \vec s + \vec c_3 \geq \vec 0
-\,\}
-.
-\end{aligned}
-\end{equation}
-To prove that $Q_i$ is indeed an overapproximation of $P_i'$,
-we need to show that for every $\vec s \in \Z^n$, for every
-$k \in \Z_{\ge 1}$ and for every $\vec f \in k \, \Delta_i(\vec s)$
-we have that
-$(\vec f, k)$ satisfies the constraints in \eqref{eq:transitive:Q}.
-If $\Delta_i(\vec s)$ is non-empty, then $\vec s$ must satisfy
-the constraints in \eqref{eq:transitive:parametric}.
-Each element $(\vec f, k) \in k \, \Delta_i'(\vec s)$ is a sum
-of $k$ elements $(\vec f_j, 1)$ in $\Delta_i'(\vec s)$.
-Each of these elements satisfies the constraints in
-\eqref{eq:transitive:non-parametric}, i.e.,
-$$
-\left[
-\begin{matrix}
-A_1 & \vec c_1
-\end{matrix}
-\right]
-\left[
-\begin{matrix}
-\vec f_j \\ 1
-\end{matrix}
-\right]
-\ge \vec 0
-.
-$$
-The sum of these elements therefore satisfies the same set of inequalities,
-i.e., $A_1 \vec f + k \vec c_1 \geq \vec 0$.
-Finally, the constraints in \eqref{eq:transitive:mixed} are such
-that for any $\vec s$ in the parameter domain of $\Delta$,
-we have $-\vec r(\vec s) \coloneqq B_3 \vec s + \vec c_3 \le \vec 0$,
-i.e., $A_3 \vec f_j \ge \vec r(\vec s) \ge \vec 0$
-and therefore also $A_3 \vec f \ge \vec r(\vec s)$.
-Note that if there are no mixed constraints and if the
-rational relaxation of $\Delta_i(\vec s)$, i.e.,
-$\{\, \vec x \in \Q^d \mid A_1 \vec x + \vec c_1 \ge \vec 0\,\}$,
-has integer vertices, then the approximation is exact, i.e.,
-$Q_i = P_i'$.  In this case, the vertices of $\Delta'_i(\vec s)$
-generate the rational cone
-$\{\, \vec x' \in \Q^{d+1} \mid \left[
-\begin{matrix}
-A_1 & \vec c_1
-\end{matrix}
-\right] \vec x' \,\}$ and therefore $\Delta'_i(\vec s)$ is
-a Hilbert basis of this cone \shortcite[Theorem~16.4]{Schrijver1986}.
-
-Note however that, as pointed out by \shortciteN{DeSmet2010personal},
-if there \emph{are} any mixed constraints, then the above procedure may
-not compute the most accurate affine approximation of
-$k \, \Delta_i(\vec s)$ with $k \ge 1$.
-In particular, we only consider the negative mixed constraints that
-happen to appear in the description of $\Delta_i(\vec s)$, while we
-should instead consider \emph{all} valid such constraints.
-It is also sufficient to consider those constraints because any
-constraint that is valid for $k \, \Delta_i(\vec s)$ is also
-valid for $1 \, \Delta_i(\vec s) = \Delta_i(\vec s)$.
-Take therefore any constraint
-$\spv a x + \spv b s + c \ge 0$ valid for $\Delta_i(\vec s)$.
-This constraint is also valid for $k \, \Delta_i(\vec s)$ iff
-$k \, \spv a x + \spv b s + c \ge 0$.
-If $\spv b s + c$ can attain any positive value, then $\spv a x$
-may be negative for some elements of $\Delta_i(\vec s)$.
-We then have $k \, \spv a x < \spv a x$ for $k > 1$ and so the constraint
-is not valid for $k \, \Delta_i(\vec s)$.
-We therefore need to impose $\spv b s + c \le 0$ for all values
-of $\vec s$ such that $\Delta_i(\vec s)$ is non-empty, i.e.,
-$\vec b$ and $c$ need to be such that $- \spv b s - c \ge 0$ is a valid
-constraint of $\Delta_i(\vec s)$.  That is, $(\vec b, c)$ are the opposites
-of the coefficients of a valid constraint of $\Delta_i(\vec s)$.
-The approximation of $k \, \Delta_i(\vec s)$ can therefore be obtained
-using three applications of Farkas' lemma.  The first obtains the coefficients
-of constraints valid for $\Delta_i(\vec s)$.  The second obtains
-the coefficients of constraints valid for the projection of $\Delta_i(\vec s)$
-onto the parameters.  The opposite of the second set is then computed
-and intersected with the first set.  The result is the set of coefficients
-of constraints valid for $k \, \Delta_i(\vec s)$.  A final application
-of Farkas' lemma is needed to obtain the approximation of
-$k \, \Delta_i(\vec s)$ itself.
-
-\begin{example}
-Consider the relation
-$$
-n \to \{\, (x, y) \to (1 + x, 1 - n + y) \mid n \ge 2 \,\}
-.
-$$
-The difference set of this relation is
-$$
-\Delta = n \to \{\, (1, 1 - n) \mid n \ge 2 \,\}
-.
-$$
-Using our approach, we would only consider the mixed constraint
-$y - 1 + n \ge 0$, leading to the following approximation of the
-transitive closure:
-$$
-n \to \{\, (x, y) \to (o_0, o_1) \mid n \ge 2 \wedge o_1 \le 1 - n + y \wedge o_0 \ge 1 + x \,\}
-.
-$$
-If, instead, we apply Farkas's lemma to $\Delta$, i.e.,
-\begin{verbatim}
-D := [n] -> { [1, 1 - n] : n >= 2 };
-CD := coefficients D;
-CD;
-\end{verbatim}
-we obtain
-\begin{verbatim}
-{ rat: coefficients[[c_cst, c_n] -> [i2, i3]] : i3 <= c_n and
-  i3 <= c_cst + 2c_n + i2 }
-\end{verbatim}
-The pure-parametric constraints valid for $\Delta$,
-\begin{verbatim}
-P := { [a,b] -> [] }(D);
-CP := coefficients P;
-CP;
-\end{verbatim}
-are
-\begin{verbatim}
-{ rat: coefficients[[c_cst, c_n] -> []] : c_n >= 0 and 2c_n >= -c_cst }
-\end{verbatim}
-Negating these coefficients and intersecting with \verb+CD+,
-\begin{verbatim}
-NCP := { rat: coefficients[[a,b] -> []]
-              -> coefficients[[-a,-b] -> []] }(CP);
-CK := wrap((unwrap CD) * (dom (unwrap NCP)));
-CK;
-\end{verbatim}
-we obtain
-\begin{verbatim}
-{ rat: [[c_cst, c_n] -> [i2, i3]] : i3 <= c_n and
-  i3 <= c_cst + 2c_n + i2 and c_n <= 0 and 2c_n <= -c_cst }
-\end{verbatim}
-The approximation for $k\,\Delta$,
-\begin{verbatim}
-K := solutions CK;
-K;
-\end{verbatim}
-is then
-\begin{verbatim}
-[n] -> { rat: [i0, i1] : i1 <= -i0 and i0 >= 1 and i1 <= 2 - n - i0 }
-\end{verbatim}
-Finally, the computed approximation for $R^+$,
-\begin{verbatim}
-T := unwrap({ [dx,dy] -> [[x,y] -> [x+dx,y+dy]] }(K));
-R := [n] -> { [x,y] -> [x+1,y+1-n] : n >= 2 };
-T := T * ((dom R) -> (ran R));
-T;
-\end{verbatim}
-is
-\begin{verbatim}
-[n] -> { [x, y] -> [o0, o1] : o1 <= x + y - o0 and
-         o0 >= 1 + x and o1 <= 2 - n + x + y - o0 and n >= 2 }
-\end{verbatim}
-\end{example}
-
-Existentially quantified variables can be handled by
-classifying them into variables that are uniquely
-determined by the parameters, variables that are independent
-of the parameters and others.  The first set can be treated
-as parameters and the second as variables.  Constraints involving
-the other existentially quantified variables are removed.
-
-\begin{example}
-Consider the relation
-$$
-R =
-n \to \{\, x \to y \mid \exists \, \alpha_0, \alpha_1: 7\alpha_0 = -2 + n \wedge 5\alpha_1 = -1 - x + y \wedge y \ge 6 + x \,\}
-.
-$$
-The difference set of this relation is
-$$
-\Delta = \Delta \, R =
-n \to \{\, x \mid \exists \, \alpha_0, \alpha_1: 7\alpha_0 = -2 + n \wedge 5\alpha_1 = -1 + x \wedge x \ge 6 \,\}
-.
-$$
-The existentially quantified variables can be defined in terms
-of the parameters and variables as
-$$
-\alpha_0 = \floor{\frac{-2 + n}7}
-\qquad
-\text{and}
-\qquad
-\alpha_1 = \floor{\frac{-1 + x}5}
-.
-$$
-$\alpha_0$ can therefore be treated as a parameter,
-while $\alpha_1$ can be treated as a variable.
-This in turn means that $7\alpha_0 = -2 + n$ can be treated as
-a purely parametric constraint, while the other two constraints are
-non-parametric.
-The corresponding $Q$~\eqref{eq:transitive:Q} is therefore
-$$
-\begin{aligned}
-n \to \{\, (x,z) \to (y,w) \mid
-\exists\, \alpha_0, \alpha_1, k, f : {} &
-k \ge 1 \wedge
-y = x + f \wedge
-w = z + k \wedge {} \\
-&
-7\alpha_0 = -2 + n \wedge
-5\alpha_1 = -k + x \wedge
-x \ge 6 k
-\,\}
-.
-\end{aligned}
-$$
-Projecting out the final coordinates encoding the length of the paths,
-results in the exact transitive closure
-$$
-R^+ =
-n \to \{\, x \to y \mid \exists \, \alpha_0, \alpha_1: 7\alpha_1 = -2 + n \wedge 6\alpha_0 \ge -x + y \wedge 5\alpha_0 \le -1 - x + y \,\}
-.
-$$
-\end{example}
-
-The fact that we ignore some impure constraints clearly leads
-to a loss of accuracy.  In some cases, some of this loss can be recovered
-by not considering the parameters in a special way.
-That is, instead of considering the set
-$$
-\Delta = \diff R =
-\vec s \mapsto
-\{\, \vec \delta \in \Z^{d} \mid \exists \vec x \to \vec y \in R :
-\vec \delta = \vec y - \vec x
-\,\}
-$$
-we consider the set
-$$
-\Delta' = \diff R' =
-\{\, \vec \delta \in \Z^{n+d} \mid \exists
-(\vec s, \vec x) \to (\vec s, \vec y) \in R' :
-\vec \delta = (\vec s - \vec s, \vec y - \vec x)
-\,\}
-.
-$$
-The first $n$ coordinates of every element in $\Delta'$ are zero.
-Projecting out these zero coordinates from $\Delta'$ is equivalent
-to projecting out the parameters in $\Delta$.
-The result is obviously a superset of $\Delta$, but all its constraints
-are of type \eqref{eq:transitive:non-parametric} and they can therefore
-all be used in the construction of $Q_i$.
-
-\begin{example}
-Consider the relation
-$$
-% [n] -> { [x, y] -> [1 + x, 1 - n + y] | n >= 2 }
-R = n \to \{\, (x, y) \to (1 + x, 1 - n + y) \mid n \ge 2 \,\}
-.
-$$
-We have
-$$
-\diff R = n \to \{\, (1, 1 - n) \mid n \ge 2 \,\}
-$$
-and so, by treating the parameters in a special way, we obtain
-the following approximation for $R^+$:
-$$
-n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge y' \le 1 - n + y \wedge x' \ge 1 + x \,\}
-.
-$$
-If we consider instead
-$$
-R' = \{\, (n, x, y) \to (n, 1 + x, 1 - n + y) \mid n \ge 2 \,\}
-$$
-then
-$$
-\diff R' = \{\, (0, 1, y) \mid y \le -1 \,\}
-$$
-and we obtain the approximation
-$$
-n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge x' \ge 1 + x \wedge y' \le x + y - x' \,\}
-.
-$$
-If we consider both $\diff R$ and $\diff R'$, then we obtain
-$$
-n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge y' \le 1 - n + y \wedge x' \ge 1 + x \wedge y' \le x + y - x' \,\}
-.
-$$
-Note, however, that this is not the most accurate affine approximation that
-can be obtained.  That would be
-$$
-n \to \{\, (x, y) \to (x', y') \mid y' \le 2 - n + x + y - x' \wedge n \ge 2 \wedge x' \ge 1 + x \,\}
-.
-$$
-\end{example}

-\subsection{Checking Exactness}
-
-The approximation $T$ for the transitive closure $R^+$ can be obtained
-by projecting out the parameter $k$ from the approximation $K$
-\eqref{eq:transitive:approx} of the power $R^k$.
-Since $K$ is an overapproximation of $R^k$, $T$ will also be an
-overapproximation of $R^+$.
-To check whether the results are exact, we need to consider two
-cases depending on whether $R$ is {\em cyclic}, where $R$ is defined
-to be cyclic if $R^+$ maps any element to itself, i.e.,
-$R^+ \cap \identity \ne \emptyset$.
-If $R$ is acyclic, then the inductive definition of
-\eqref{eq:transitive:inductive} is equivalent to its completion,
-i.e.,
-$$
-R^+ = R \cup \left(R \circ R^+\right)
-$$
-is a defining property.
-Since $T$ is known to be an overapproximation, we only need to check
-whether
-$$
-T \subseteq R \cup \left(R \circ T\right)
-.
-$$
-This is essentially Theorem~5 of \shortciteN{Kelly1996closure}.
-The only difference is that they only consider lexicographically
-forward relations, a special case of acyclic relations.
-
-If, on the other hand, $R$ is cyclic, then we have to resort
-to checking whether the approximation $K$ of the power is exact.
-Note that $T$ may be exact even if $K$ is not exact, so the check
-is sound, but incomplete.
-To check exactness of the power, we simply need to check
-\eqref{eq:transitive:power}.  Since again $K$ is known
-to be an overapproximation, we only need to check whether
-$$
-\begin{aligned}
-K'|_{y_{d+1} - x_{d+1} = 1} & \subseteq R'
-\\
-K'|_{y_{d+1} - x_{d+1} \ge 2} & \subseteq R' \circ K'|_{y_{d+1} - x_{d+1} \ge 1}
-,
-\end{aligned}
-$$
-where $R' = \{\, \vec x' \to \vec y' \mid \vec x \to \vec y \in R
-\wedge y_{d+1} - x_{d+1} = 1\,\}$, i.e., $R$ extended with path
-lengths equal to 1.
-
-All that remains is to explain how to check the cyclicity of $R$.
-Note that the exactness on the power is always sound, even
-in the acyclic case, so we only need to be careful that we find
-all cyclic cases.  Now, if $R$ is cyclic, i.e.,
-$R^+ \cap \identity \ne \emptyset$, then, since $T$ is
-an overapproximation of $R^+$, also
-$T \cap \identity \ne \emptyset$.  This in turn means
-that $\Delta \, K'$ contains a point whose first $d$ coordinates
-are zero and whose final coordinate is positive.
-In the implementation we currently perform this test on $P'$ instead of $K'$.
-Note that if $R^+$ is acyclic and $T$ is not, then the approximation
-is clearly not exact and the approximation of the power $K$
-will not be exact either.
-
-\subsection{Decomposing $R$ into strongly connected components}
-
-If the input relation $R$ is a union of several basic relations
-that can be partially ordered
-then the accuracy of the approximation may be improved by computing
-an approximation of each strongly connected components separately.
-For example, if $R = R_1 \cup R_2$ and $R_1 \circ R_2 = \emptyset$,
-then we know that any path that passes through $R_2$ cannot later
-pass through $R_1$, i.e.,
-\begin{equation}
-\label{eq:transitive:components}
-R^+ = R_1^+ \cup R_2^+ \cup \left(R_2^+ \circ R_1^+\right)
-.
-\end{equation}
-We can therefore compute (approximations of) transitive closures
-of $R_1$ and $R_2$ separately.
-Note, however, that the condition $R_1 \circ R_2 = \emptyset$
-is actually too strong.
-If $R_1 \circ R_2$ is a subset of $R_2 \circ R_1$
-then we can reorder the segments
-in any path that moves through both $R_1$ and $R_2$ to
-first move through $R_1$ and then through $R_2$.
-
-This idea can be generalized to relations that are unions
-of more than two basic relations by constructing the
-strongly connected components in the graph with as vertices
-the basic relations and an edge between two basic relations
-$R_i$ and $R_j$ if $R_i$ needs to follow $R_j$ in some paths.
-That is, there is an edge from $R_i$ to $R_j$ iff
-\begin{equation}
-\label{eq:transitive:edge}
-R_i \circ R_j
-\not\subseteq
-R_j \circ R_i
-.
-\end{equation}
-The components can be obtained from the graph by applying
-Tarjan's algorithm \shortcite{Tarjan1972}.
-
-In practice, we compute the (extended) powers $K_i'$ of each component
-separately and then compose them as in \eqref{eq:transitive:decompose}.
-Note, however, that in this case the order in which we apply them is
-important and should correspond to a topological ordering of the
-strongly connected components.  Simply applying Tarjan's
-algorithm will produce topologically sorted strongly connected components.
-The graph on which Tarjan's algorithm is applied is constructed on-the-fly.
-That is, whenever the algorithm checks if there is an edge between
-two vertices, we evaluate \eqref{eq:transitive:edge}.
-The exactness check is performed on each component separately.
-If the approximation turns out to be inexact for any of the components,
-then the entire result is marked inexact and the exactness check
-is skipped on the components that still need to be handled.
-
-It should be noted that \eqref{eq:transitive:components}
-is only valid for exact transitive closures.
-If overapproximations are computed in the right hand side, then the result will
-still be an overapproximation of the left hand side, but this result
-may not be transitively closed.  If we only separate components based
-on the condition $R_i \circ R_j = \emptyset$, then there is no problem,
-as this condition will still hold on the computed approximations
-of the transitive closures.  If, however, we have exploited
-\eqref{eq:transitive:edge} during the decomposition and if the
-result turns out not to be exact, then we check whether
-the result is transitively closed.  If not, we recompute
-the transitive closure, skipping the decomposition.
-Note that testing for transitive closedness on the result may
-be fairly expensive, so we may want to make this check
-configurable.

-$$
-\begin{aligned}
-R_1 &= n \mapsto \{\, (i,j) \to (i+3,j) \mid

-.
-\end{aligned}
-$$
-The figure shows this relation for $n = 7$.
-Both
-$R_3 \circ R_1 \subseteq R_1 \circ R_3$
-and
-$R_3 \circ R_2 \subseteq R_2 \circ R_3$,
-which the reader can verify using the {\tt iscc} calculator:
-\begin{verbatim}
-R1 := [n] -> { [i,j] -> [i+3,j] : i <= 2 j - 4 and i <= n - 3 and
-                                  j <= 2 i - 1 and j <= n };
-R2 := [n] -> { [i,j] -> [i,j+3] : i <= 2 j - 1 and i <= n and
-                                  j <= 2 i - 4 and j <= n - 3 };
-R3 := [n] -> { [i,j] -> [i+1,j+1] : i <= 2 j - 1 and i <= n - 1 and
-                                    j <= 2 i - 1 and j <= n - 1 };
-(R1 . R3) - (R3 . R1);
-(R2 . R3) - (R3 . R2);
-\end{verbatim}
-$R_3$ can therefore be moved forward in any path.
-For the other two basic relations, we have both
-$R_2 \circ R_1 \not\subseteq R_1 \circ R_2$
-and
-$R_1 \circ R_2 \not\subseteq R_2 \circ R_1$
-and so $R_1$ and $R_2$ form a strongly connected component.
-By computing the power of $R_3$ and $R_1 \cup R_2$ separately
-and composing the results, the power of $R$ can be computed exactly
-using \eqref{eq:transitive:singleton}.
-As explained by \shortciteN{Beletska2009}, applying the same formula
-to $R$ directly, without a decomposition, would result in
-an overapproximation of the power.
-\end{example}
-
-\subsection{Partitioning the domains and ranges of $R$}
-
-The algorithm of \autoref{s:power} assumes that the input relation $R$
-can be treated as a union of translations.
-This is a reasonable assumption if $R$ maps elements of a given
-abstract domain to the same domain.
-However, if $R$ is a union of relations that map between different
-domains, then this assumption no longer holds.
-In particular, when an entire dependence graph is encoded
-in a single relation, as is done by, e.g.,
-\shortciteN[Section~6.1]{Barthou2000MSE}, then it does not make
-sense to look at differences between iterations of different domains.
-Now, arguably, a modified Floyd-Warshall algorithm should
-be applied to the dependence graph, as advocated by
-\shortciteN{Kelly1996closure}, with the transitive closure operation
-only being applied to relations from a given domain to itself.
-However, it is also possible to detect disjoint domains and ranges
-and to apply Floyd-Warshall internally.

-\end{algorithm}
-
-Let the input relation $R$ be a union of $m$ basic relations $R_i$.
-Let $D_{2i}$ be the domains of $R_i$ and $D_{2i+1}$ the ranges of $R_i$.
-The first step is to group overlapping $D_j$ until a partition is
-obtained.  If the resulting partition consists of a single part,
-then we continue with the algorithm of \autoref{s:power}.
-Otherwise, we apply Floyd-Warshall on the graph with as vertices
-the parts of the partition and as edges the $R_i$ attached to
-the appropriate pairs of vertices.
-In particular, let there be $n$ parts $P_k$ in the partition.
-We construct $n^2$ relations
-$$
-R_{pq} \coloneqq \bigcup_{i \text{ s.t. } \domain R_i \subseteq P_p \wedge
-				 \range R_i \subseteq P_q} R_i
-,
-$$
-apply \autoref{a:Floyd} and return the union of all resulting
-$R_{pq}$ as the transitive closure of $R$.
-Each iteration of the $r$-loop in \autoref{a:Floyd} updates
-all relations $R_{pq}$ to include paths that go from $p$ to $r$,
-possibly stay there for a while, and then go from $r$ to $q$.
-Note that paths that ``stay in $r$'' include all paths that
-pass through earlier vertices since $R_{rr}$ itself has been updated
-accordingly in previous iterations of the outer loop.
-In principle, it would be sufficient to use the $R_{pr}$
-and $R_{rq}$ computed in the previous iteration of the
-$r$-loop in Line~\ref{l:Floyd:update}.
-However, from an implementation perspective, it is easier
-to allow either or both of these to have been updated
-in the same iteration of the $r$-loop.
-This may result in duplicate paths, but these can usually
-be removed by coalescing (\autoref{s:coalescing}) the result of the union
-in Line~\ref{l:Floyd:update}, which should be done in any case.
-The transitive closure in Line~\ref{l:Floyd:closure}
-is performed using a recursive call.  This recursive call
-includes the partitioning step, but the resulting partition will
-usually be a singleton.
-The result of the recursive call will either be exact or an
-overapproximation.  The final result of Floyd-Warshall is therefore
-also exact or an overapproximation.

-\end{figure}
-\begin{example}
-Consider the relation on the right of Figure~1 of
-\shortciteN{Beletska2009},
-reproduced in \autoref{f:COCOA:1}.
-This relation can be described as
-$$
-\begin{aligned}
-\{\, (x, y) \to (x_2, y_2) \mid {} & (3y = 2x \wedge x_2 = x \wedge 3y_2 = 3 + 2x \wedge x \ge 0 \wedge x \le 3) \vee {} \\
-& (x_2 = 1 + x \wedge y_2 = y \wedge x \ge 0 \wedge 3y \ge 2 + 2x \wedge x \le 2 \wedge 3y \le 3 + 2x) \,\}
-.
-\end{aligned}
-$$
-Note that the domain of the upward relation overlaps with the range
-of the rightward relation and vice versa, but that the domain
-of neither relation overlaps with its own range or the domain of
-the other relation.
-The domains and ranges can therefore be partitioned into two parts,
-$P_0$ and $P_1$, shown as the white and black dots in \autoref{f:COCOA:1},
-respectively.
-Initially, we have
-$$
-\begin{aligned}
-R_{00} & = \emptyset
-\\
-R_{01} & = 
-\{\, (x, y) \to (x+1, y) \mid 
-(x \ge 0 \wedge 3y \ge 2 + 2x \wedge x \le 2 \wedge 3y \le 3 + 2x) \,\}
-\\
-R_{10} & =
-\{\, (x, y) \to (x_2, y_2) \mid (3y = 2x \wedge x_2 = x \wedge 3y_2 = 3 + 2x \wedge x \ge 0 \wedge x \le 3) \,\}
-\\
-R_{11} & = \emptyset
-.
-\end{aligned}
-$$
-In the first iteration, $R_{00}$ remains the same ($\emptyset^+ = \emptyset$).
-$R_{01}$ and $R_{10}$ are therefore also unaffected, but
-$R_{11}$ is updated to include $R_{01} \circ R_{10}$, i.e.,
-the dashed arrow in the figure.
-This new $R_{11}$ is obviously transitively closed, so it is not
-changed in the second iteration and it does not have an effect
-on $R_{01}$ and $R_{10}$.  However, $R_{00}$ is updated to
-include $R_{10} \circ R_{01}$, i.e., the dotted arrow in the figure.
-The transitive closure of the original relation is then equal to
-$R_{00} \cup R_{01} \cup R_{10} \cup R_{11}$.
-\end{example}
-
-\subsection{Incremental Computation}
-\label{s:incremental}
-
-In some cases it is possible and useful to compute the transitive closure
-of union of basic relations incrementally.  In particular,
-if $R$ is a union of $m$ basic maps,
-$$
-R = \bigcup_j R_j
-,
-$$
-then we can pick some $R_i$ and compute the transitive closure of $R$ as
-\begin{equation}
-\label{eq:transitive:incremental}
-R^+ = R_i^+ \cup
-\left(
-\bigcup_{j \ne i}
-R_i^* \circ R_j \circ R_i^*
-\right)^+
-.
-\end{equation}
-For this approach to be successful, it is crucial that each
-of the disjuncts in the argument of the second transitive
-closure in \eqref{eq:transitive:incremental} be representable
-as a single basic relation, i.e., without a union.
-If this condition holds, then by using \eqref{eq:transitive:incremental},
-the number of disjuncts in the argument of the transitive closure
-can be reduced by one.
-Now, $R_i^* = R_i^+ \cup \identity$, but in some cases it is possible
-to relax the constraints of $R_i^+$ to include part of the identity relation,
-say on domain $D$.  We will use the notation
-${\cal C}(R_i,D) = R_i^+ \cup \identity_D$ to represent
-this relaxed version of $R^+$.
-\shortciteN{Kelly1996closure} use the notation $R_i^?$.
-${\cal C}(R_i,D)$ can be computed by allowing $k$ to attain
-the value $0$ in \eqref{eq:transitive:Q} and by using
-$$
-P \cap \left(D \to D\right)
-$$
-instead of \eqref{eq:transitive:approx}.
-Typically, $D$ will be a strict superset of both $\domain R_i$
-and $\range R_i$.  We therefore need to check that domain
-and range of the transitive closure are part of ${\cal C}(R_i,D)$,
-i.e., the part that results from the paths of positive length ($k \ge 1$),
-are equal to the domain and range of $R_i$.
-If not, then the incremental approach cannot be applied for
-the given choice of $R_i$ and $D$.
-
-In order to be able to replace $R^*$ by ${\cal C}(R_i,D)$
-in \eqref{eq:transitive:incremental}, $D$ should be chosen
-to include both $\domain R$ and $\range R$, i.e., such
-that $\identity_D \circ R_j \circ \identity_D = R_j$ for all $j\ne i$.
-\shortciteN{Kelly1996closure} say that they use
-$D = \domain R_i \cup \range R_i$, but presumably they mean that
-they use $D = \domain R \cup \range R$.
-Now, this expression of $D$ contains a union, so it not directly usable.
-\shortciteN{Kelly1996closure} do not explain how they avoid this union.
-Apparently, in their implementation,
-they are using the convex hull of $\domain R \cup \range R$
-or at least an approximation of this convex hull.
-We use the simple hull (\autoref{s:simple hull}) of $\domain R \cup \range R$.
-
-It is also possible to use a domain $D$ that does {\em not\/}
-include $\domain R \cup \range R$, but then we have to
-compose with ${\cal C}(R_i,D)$ more selectively.
-In particular, if we have
-\begin{equation}
-\label{eq:transitive:right}
-\text{for each $j \ne i$ either }
-\domain R_j \subseteq D \text{ or } \domain R_j \cap \range R_i = \emptyset
-\end{equation}
-and, similarly,
-\begin{equation}
-\label{eq:transitive:left}
-\text{for each $j \ne i$ either }
-\range R_j \subseteq D \text{ or } \range R_j \cap \domain R_i = \emptyset
-\end{equation}
-then we can refine \eqref{eq:transitive:incremental} to
-$$
-R_i^+ \cup
-\left(
-\left(
-\bigcup_{\shortstack{$\scriptstyle\domain R_j \subseteq D $\\
-		     $\scriptstyle\range R_j \subseteq D$}}
-{\cal C} \circ R_j \circ {\cal C}
-\right)

-$$
-If only property~\eqref{eq:transitive:right} holds,

-
-It should be noted that if we want the result of the incremental
-approach to be transitively closed, then we can only apply it
-if all of the transitive closure operations involved are exact.
-If, say, the second transitive closure in \eqref{eq:transitive:incremental}
-contains extra elements, then the result does not necessarily contain
-the composition of these extra elements with powers of $R_i$.
-
-\subsection{An {\tt Omega}-like implementation}
-
-While the main algorithm of \shortciteN{Kelly1996closure} is
-designed to compute and underapproximation of the transitive closure,
-the authors mention that they could also compute overapproximations.
-In this section, we describe our implementation of an algorithm
-that is based on their ideas.
-Note that the {\tt Omega} library computes underapproximations
-\shortcite[Section 6.4]{Omega_lib}.
-
-The main tool is Equation~(2) of \shortciteN{Kelly1996closure}.
-The input relation $R$ is first overapproximated by a ``d-form'' relation
-$$
-\{\, \vec i \to \vec j \mid \exists \vec \alpha :
-\vec L \le \vec j - \vec i \le \vec U
-\wedge
-(\forall p : j_p - i_p = M_p \alpha_p)
-\,\}
-,
-$$
-where $p$ ranges over the dimensions and $\vec L$, $\vec U$ and
-$\vec M$ are constant integer vectors.  The elements of $\vec U$
-may be $\infty$, meaning that there is no upper bound corresponding
-to that element, and similarly for $\vec L$.
-Such an overapproximation can be obtained by computing strides,
-lower and upper bounds on the difference set $\Delta \, R$.
-The transitive closure of such a ``d-form'' relation is
-\begin{equation}
-\label{eq:omega}
-\{\, \vec i \to \vec j \mid \exists \vec \alpha, k :
-k \ge 1 \wedge
-k \, \vec L \le \vec j - \vec i \le k \, \vec U
-\wedge
-(\forall p : j_p - i_p = M_p \alpha_p)
-\,\}
-.
-\end{equation}
-The domain and range of this transitive closure are then
-intersected with those of the input relation.
-This is a special case of the algorithm in \autoref{s:power}.
-
-In their algorithm for computing lower bounds, the authors
-use the above algorithm as a substep on the disjuncts in the relation.
-At the end, they say
-\begin{quote}
-If an upper bound is required, it can be calculated in a manner
-similar to that of a single conjunct [sic] relation.
-\end{quote}
-Presumably, the authors mean that a ``d-form'' approximation
-of the whole input relation should be used.
-However, the accuracy can be improved by also trying to
-apply the incremental technique from the same paper,
-which is explained in more detail in \autoref{s:incremental}.
-In this case, ${\cal C}(R_i,D)$ can be obtained by
-allowing the value zero for $k$ in \eqref{eq:omega},
-i.e., by computing
-$$
-\{\, \vec i \to \vec j \mid \exists \vec \alpha, k :
-k \ge 0 \wedge
-k \, \vec L \le \vec j - \vec i \le k \, \vec U
-\wedge
-(\forall p : j_p - i_p = M_p \alpha_p)
-\,\}
-.
-$$
-In our implementation we take as $D$ the simple hull
-(\autoref{s:simple hull}) of $\domain R \cup \range R$.
-To determine whether it is safe to use ${\cal C}(R_i,D)$,
-we check the following conditions, as proposed by
-\shortciteN{Kelly1996closure}:
-${\cal C}(R_i,D) - R_i^+$ is not a union and for each $j \ne i$
-the condition
-$$
-\left({\cal C}(R_i,D) - R_i^+\right)
-\circ
-R_j
-\circ
-\left({\cal C}(R_i,D) - R_i^+\right)
-=
-R_j
-$$
-holds.

-  ABSTRACT = {  Parallel computers are difficult to program efficiently.  We believe
-  that a good way to help programmers write efficient programs is to
-  provide them with tools that show them how their programs behave on
-  a parallel computer.  Data distribution is the major performance
-  factor of data-parallel programs and so automatic data layout for
-  HPF programs has been studied by many researchers recently.  The
-  communication volume induced by a data distribution is a good
-  estimator of the efficiency of this data distribution.
-
-  We present here a symbolic method to compute the communication
-  volume generated by a given data distribution during the program
-  writing phase (before compilation). We stay machine-independent to
-  assure portability.  Our goal is to help the programmer understand
-  the data movements its program generates and thus find a good data
-  distribution. Our method is based on parametric polyhedral
-  computations. It can be applied to a large class of regular codes.},

-=head1 Introduction
-
-C<isl> is a thread-safe C library for manipulating
-sets and relations of integer points bounded by affine constraints.
-The descriptions of the sets and relations may involve
-both parameters and existentially quantified variables.
-All computations are performed in exact integer arithmetic
-using C<GMP>.
-The C<isl> library offers functionality that is similar
-to that offered by the C<Omega> and C<Omega+> libraries,
-but the underlying algorithms are in most cases completely different.
-
-The library is by no means complete and some fairly basic
-functionality is still missing.
-Still, even in its current form, the library has been successfully
-used as a backend polyhedral library for the polyhedral
-scanner C<CLooG> and as part of an equivalence checker of
-static affine programs.
-For bug reports, feature requests and questions,
-visit the the discussion group at
-L<http://groups.google.com/group/isl-development>.

-=head1 Installation
-
-The source of C<isl> can be obtained either as a tarball
-or from the git repository.  Both are available from
-L<http://freshmeat.net/projects/isl/>.
-The installation process depends on how you obtained
-the source.
-
-=head2 Installation from the git repository
-
-=over
-
-=item 1 Clone or update the repository
-
-The first time the source is obtained, you need to clone
-the repository.
-
-	git clone git://repo.or.cz/isl.git
-
-To obtain updates, you need to pull in the latest changes
-
-	git pull
-
-=item 2 Generate C<configure>
-
-	./autogen.sh
-

-
-=item 1 Obtain C<GMP>
-
-Building C<isl> requires C<GMP>, including its headers files.
-Your distribution may not provide these header files by default
-and you may need to install a package called C<gmp-devel> or something
-similar.  Alternatively, C<GMP> can be built from
-source, available from L<http://gmplib.org/>.
-
-=item 2 Configure
-
-C<isl> uses the standard C<autoconf> C<configure> script.
-To run it, just type
-
-	./configure
-
-optionally followed by some configure options.
-A complete list of options can be obtained by running
-
-	./configure --help
-
-Below we discuss some of the more common options.
-
-C<isl> can optionally use C<piplib>, but no
-C<piplib> functionality is currently used by default.
-The C<--with-piplib> option can
-be used to specify which C<piplib>
-library to use, either an installed version (C<system>),
-an externally built version (C<build>)
-or no version (C<no>).  The option C<build> is mostly useful
-in C<configure> scripts of larger projects that bundle both C<isl>
-and C<piplib>.

-=head2 Initialization
-
-All manipulations of integer sets and relations occur within
-the context of an C<isl_ctx>.
-A given C<isl_ctx> can only be used within a single thread.
-All arguments of a function are required to have been allocated
-within the same context.
-There are currently no functions available for moving an object
-from one C<isl_ctx> to another C<isl_ctx>.  This means that
-there is currently no way of safely moving an object from one
-thread to another, unless the whole C<isl_ctx> is moved.
-
-An C<isl_ctx> can be allocated using C<isl_ctx_alloc> and
-freed using C<isl_ctx_free>.
-All objects allocated within an C<isl_ctx> should be freed
-before the C<isl_ctx> itself is freed.
-
-	isl_ctx *isl_ctx_alloc();
-	void isl_ctx_free(isl_ctx *ctx);
-
-=head2 Integers
-
-All operations on integers, mainly the coefficients
-of the constraints describing the sets and relations,
-are performed in exact integer arithmetic using C<GMP>.
-However, to allow future versions of C<isl> to optionally
-support fixed integer arithmetic, all calls to C<GMP>
-are wrapped inside C<isl> specific macros.
-The basic type is C<isl_int> and the operations below
-are available on this type.
-The meanings of these operations are essentially the same
-as their C<GMP> C<mpz_> counterparts.
-As always with C<GMP> types, C<isl_int>s need to be
-initialized with C<isl_int_init> before they can be used
-and they need to be released with C<isl_int_clear>
-after the last use.
-The user should not assume that an C<isl_int> is represented
-as a C<mpz_t>, but should instead explicitly convert between
-C<mpz_t>s and C<isl_int>s using C<isl_int_set_gmp> and
-C<isl_int_get_gmp> whenever a C<mpz_t> is required.

-=head2 Sets and Relations
-
-C<isl> uses six types of objects for representing sets and relations,
-C<isl_basic_set>, C<isl_basic_map>, C<isl_set>, C<isl_map>,
-C<isl_union_set> and C<isl_union_map>.
-C<isl_basic_set> and C<isl_basic_map> represent sets and relations that
-can be described as a conjunction of affine constraints, while
-C<isl_set> and C<isl_map> represent unions of
-C<isl_basic_set>s and C<isl_basic_map>s, respectively.
-However, all C<isl_basic_set>s or C<isl_basic_map>s in the union need
-to have the same dimension.  C<isl_union_set>s and C<isl_union_map>s
-represent unions of C<isl_set>s or C<isl_map>s of I<different> dimensions,
-where dimensions with different space names
-(see L<Dimension Specifications>) are considered different as well.
-The difference between sets and relations (maps) is that sets have
-one set of variables, while relations have two sets of variables,
-input variables and output variables.
-
-=head2 Memory Management
-
-Since a high-level operation on sets and/or relations usually involves
-several substeps and since the user is usually not interested in
-the intermediate results, most functions that return a new object
-will also release all the objects passed as arguments.
-If the user still wants to use one or more of these arguments
-after the function call, she should pass along a copy of the
-object rather than the object itself.
-The user is then responsible for making sure that the original
-object gets used somewhere else or is explicitly freed.
-
-The arguments and return values of all documents functions are
-annotated to make clear which arguments are released and which
-arguments are preserved.  In particular, the following annotations
-are used
-
-=over
-
-=item C<__isl_give>
-
-C<__isl_give> means that a new object is returned.
-The user should make sure that the returned pointer is
-used exactly once as a value for an C<__isl_take> argument.
-In between, it can be used as a value for as many
-C<__isl_keep> arguments as the user likes.
-There is one exception, and that is the case where the
-pointer returned is C<NULL>.  Is this case, the user
-is free to use it as an C<__isl_take> argument or not.
-
-=item C<__isl_take>
-
-C<__isl_take> means that the object the argument points to
-is taken over by the function and may no longer be used
-by the user as an argument to any other function.
-The pointer value must be one returned by a function
-returning an C<__isl_give> pointer.
-If the user passes in a C<NULL> value, then this will
-be treated as an error in the sense that the function will
-not perform its usual operation.  However, it will still
-make sure that all the the other C<__isl_take> arguments
-are released.
-
-=item C<__isl_keep>
-
-C<__isl_keep> means that the function will only use the object
-temporarily.  After the function has finished, the user
-can still use it as an argument to other functions.
-A C<NULL> value will be treated in the same way as
-a C<NULL> value for an C<__isl_take> argument.
-

-
-=head2 Dimension Specifications
-
-Whenever a new set or relation is created from scratch,
-its dimension needs to be specified using an C<isl_dim>.
-
-	#include <isl/dim.h>
-	__isl_give isl_dim *isl_dim_alloc(isl_ctx *ctx,
-		unsigned nparam, unsigned n_in, unsigned n_out);
-	__isl_give isl_dim *isl_dim_set_alloc(isl_ctx *ctx,
-		unsigned nparam, unsigned dim);
-	__isl_give isl_dim *isl_dim_copy(__isl_keep isl_dim *dim);
-	void isl_dim_free(__isl_take isl_dim *dim);
-	unsigned isl_dim_size(__isl_keep isl_dim *dim,
-		enum isl_dim_type type);
-
-The dimension specification used for creating a set
-needs to be created using C<isl_dim_set_alloc>, while
-that for creating a relation
-needs to be created using C<isl_dim_alloc>.
-C<isl_dim_size> can be used
-to find out the number of dimensions of each type in
-a dimension specification, where type may be
-C<isl_dim_param>, C<isl_dim_in> (only for relations),
-C<isl_dim_out> (only for relations), C<isl_dim_set>
-(only for sets) or C<isl_dim_all>.
-
-It is often useful to create objects that live in the
-same space as some other object.  This can be accomplished
-by creating the new objects
-(see L<Creating New Sets and Relations> or
-L<Creating New (Piecewise) Quasipolynomials>) based on the dimension
-specification of the original object.
-
-	#include <isl/set.h>
-	__isl_give isl_dim *isl_basic_set_get_dim(
-		__isl_keep isl_basic_set *bset);
-	__isl_give isl_dim *isl_set_get_dim(__isl_keep isl_set *set);

-
-	#include <isl/aff.h>
-	__isl_give isl_dim *isl_aff_get_dim(
-		__isl_keep isl_aff *aff);
-	__isl_give isl_dim *isl_pw_aff_get_dim(
-		__isl_keep isl_pw_aff *pwaff);
-
-	#include <isl/point.h>
-	__isl_give isl_dim *isl_point_get_dim(
-		__isl_keep isl_point *pnt);
-
-The names of the individual dimensions may be set or read off
-using the following functions.
-
-	#include <isl/dim.h>
-	__isl_give isl_dim *isl_dim_set_name(__isl_take isl_dim *dim,
-				 enum isl_dim_type type, unsigned pos,
-				 __isl_keep const char *name);
-	__isl_keep const char *isl_dim_get_name(__isl_keep isl_dim *dim,
-				 enum isl_dim_type type, unsigned pos);
-
-Note that C<isl_dim_get_name> returns a pointer to some internal
-data structure, so the result can only be used while the
-corresponding C<isl_dim> is alive.
-Also note that every function that operates on two sets or relations
-requires that both arguments have the same parameters.  This also
-means that if one of the arguments has named parameters, then the
-other needs to have named parameters too and the names need to match.
-Pairs of C<isl_union_set> and/or C<isl_union_map> arguments may
-have different parameters (as long as they are named), in which case
-the result will have as parameters the union of the parameters of
-the arguments.
-
-The names of entire spaces may be set or read off
-using the following functions.
-
-	#include <isl/dim.h>
-	__isl_give isl_dim *isl_dim_set_tuple_name(
-		__isl_take isl_dim *dim,
-		enum isl_dim_type type, const char *s);
-	const char *isl_dim_get_tuple_name(__isl_keep isl_dim *dim,
-		enum isl_dim_type type);
-
-The C<dim> argument needs to be one of C<isl_dim_in>, C<isl_dim_out>
-or C<isl_dim_set>.  As with C<isl_dim_get_name>,
-the C<isl_dim_get_tuple_name> function returns a pointer to some internal
-data structure.
-Binary operations require the corresponding spaces of their arguments
-to have the same name.
-
-Spaces can be nested.  In particular, the domain of a set or
-the domain or range of a relation can be a nested relation.
-The following functions can be used to construct and deconstruct
-such nested dimension specifications.
-
-	#include <isl/dim.h>
-	int isl_dim_is_wrapping(__isl_keep isl_dim *dim);
-	__isl_give isl_dim *isl_dim_wrap(__isl_take isl_dim *dim);
-	__isl_give isl_dim *isl_dim_unwrap(__isl_take isl_dim *dim);
-
-The input to C<isl_dim_is_wrapping> and C<isl_dim_unwrap> should
-be the dimension specification of a set, while that of
-C<isl_dim_wrap> should be the dimension specification of a relation.
-Conversely, the output of C<isl_dim_unwrap> is the dimension specification
-of a relation, while that of C<isl_dim_wrap> is the dimension specification
-of a set.
-
-Dimension specifications can be created from other dimension
-specifications using the following functions.
-
-	__isl_give isl_dim *isl_dim_domain(__isl_take isl_dim *dim);
-	__isl_give isl_dim *isl_dim_from_domain(__isl_take isl_dim *dim);
-	__isl_give isl_dim *isl_dim_range(__isl_take isl_dim *dim);
-	__isl_give isl_dim *isl_dim_from_range(__isl_take isl_dim *dim);
-	__isl_give isl_dim *isl_dim_reverse(__isl_take isl_dim *dim);
-	__isl_give isl_dim *isl_dim_join(__isl_take isl_dim *left,
-		__isl_take isl_dim *right);
-	__isl_give isl_dim *isl_dim_align_params(
-		__isl_take isl_dim *dim1, __isl_take isl_dim *dim2)
-	__isl_give isl_dim *isl_dim_insert(__isl_take isl_dim *dim,
-		enum isl_dim_type type, unsigned pos, unsigned n);
-	__isl_give isl_dim *isl_dim_add(__isl_take isl_dim *dim,
-		enum isl_dim_type type, unsigned n);
-	__isl_give isl_dim *isl_dim_drop(__isl_take isl_dim *dim,
-		enum isl_dim_type type, unsigned first, unsigned n);
-	__isl_give isl_dim *isl_dim_map_from_set(
-		__isl_take isl_dim *dim);
-	__isl_give isl_dim *isl_dim_zip(__isl_take isl_dim *dim);
-
-Note that if dimensions are added or removed from a space, then
-the name and the internal structure are lost.
-
-=head2 Local Spaces
-
-A local space is essentially a dimension specification with
-zero or more existentially quantified variables.
-The local space of a basic set or relation can be obtained
-using the following functions.
-
-	#include <isl/set.h>
-	__isl_give isl_local_space *isl_basic_set_get_local_space(
-		__isl_keep isl_basic_set *bset);
-
-	#include <isl/map.h>
-	__isl_give isl_local_space *isl_basic_map_get_local_space(
-		__isl_keep isl_basic_map *bmap);
-
-A new local space can be created from a dimension specification using
-
-	#include <isl/local_space.h>
-	__isl_give isl_local_space *isl_local_space_from_dim(
-		__isl_take isl_dim *dim);
-
-They can be inspected, copied and freed using the following functions.
-
-	#include <isl/local_space.h>
-	isl_ctx *isl_local_space_get_ctx(
-		__isl_keep isl_local_space *ls);
-	int isl_local_space_dim(__isl_keep isl_local_space *ls,
-		enum isl_dim_type type);
-	const char *isl_local_space_get_dim_name(
-		__isl_keep isl_local_space *ls,
-		enum isl_dim_type type, unsigned pos);
-	__isl_give isl_local_space *isl_local_space_set_dim_name(
-		__isl_take isl_local_space *ls,
-		enum isl_dim_type type, unsigned pos, const char *s);
-	__isl_give isl_dim *isl_local_space_get_dim(
-		__isl_keep isl_local_space *ls);
-	__isl_give isl_div *isl_local_space_get_div(
-		__isl_keep isl_local_space *ls, int pos);
-	__isl_give isl_local_space *isl_local_space_copy(
-		__isl_keep isl_local_space *ls);
-	void *isl_local_space_free(__isl_take isl_local_space *ls);
-
-Two local spaces can be compared using
-
-	int isl_local_space_is_equal(__isl_keep isl_local_space *ls1,
-		__isl_keep isl_local_space *ls2);
-
-Local spaces can be created from other local spaces
-using the following functions.
-
-	__isl_give isl_local_space *isl_local_space_from_domain(
-		__isl_take isl_local_space *ls);
-	__isl_give isl_local_space *isl_local_space_add_dims(
-		__isl_take isl_local_space *ls,
-		enum isl_dim_type type, unsigned n);
-	__isl_give isl_local_space *isl_local_space_insert_dims(
-		__isl_take isl_local_space *ls,
-		enum isl_dim_type type, unsigned first, unsigned n);
-	__isl_give isl_local_space *isl_local_space_drop_dims(
-		__isl_take isl_local_space *ls,
-		enum isl_dim_type type, unsigned first, unsigned n);
-
-=head2 Input and Output
-
-C<isl> supports its own input/output format, which is similar
-to the C<Omega> format, but also supports the C<PolyLib> format
-in some cases.
-
-=head3 C<isl> format
-
-The C<isl> format is similar to that of C<Omega>, but has a different
-syntax for describing the parameters and allows for the definition
-of an existentially quantified variable as the integer division
-of an affine expression.
-For example, the set of integers C<i> between C<0> and C<n>
-such that C<i % 10 <= 6> can be described as
-
-	[n] -> { [i] : exists (a = [i/10] : 0 <= i and i <= n and
-				i - 10 a <= 6) }
-
-A set or relation can have several disjuncts, separated
-by the keyword C<or>.  Each disjunct is either a conjunction
-of constraints or a projection (C<exists>) of a conjunction
-of constraints.  The constraints are separated by the keyword
-C<and>.
-
-=head3 C<PolyLib> format
-
-If the represented set is a union, then the first line
-contains a single number representing the number of disjuncts.
-Otherwise, a line containing the number C<1> is optional.
-
-Each disjunct is represented by a matrix of constraints.
-The first line contains two numbers representing
-the number of rows and columns,
-where the number of rows is equal to the number of constraints
-and the number of columns is equal to two plus the number of variables.
-The following lines contain the actual rows of the constraint matrix.
-In each row, the first column indicates whether the constraint
-is an equality (C<0>) or inequality (C<1>).  The final column
-corresponds to the constant term.
-
-If the set is parametric, then the coefficients of the parameters
-appear in the last columns before the constant column.
-The coefficients of any existentially quantified variables appear
-between those of the set variables and those of the parameters.
-
-=head3 Extended C<PolyLib> format
-
-The extended C<PolyLib> format is nearly identical to the
-C<PolyLib> format.  The only difference is that the line
-containing the number of rows and columns of a constraint matrix
-also contains four additional numbers:
-the number of output dimensions, the number of input dimensions,
-the number of local dimensions (i.e., the number of existentially
-quantified variables) and the number of parameters.
-For sets, the number of ``output'' dimensions is equal
-to the number of set dimensions, while the number of ``input''
-dimensions is zero.

-=head2 Inspecting Sets and Relations
-
-Usually, the user should not have to care about the actual constraints
-of the sets and maps, but should instead apply the abstract operations
-explained in the following sections.
-Occasionally, however, it may be required to inspect the individual
-coefficients of the constraints.  This section explains how to do so.
-In these cases, it may also be useful to have C<isl> compute
-an explicit representation of the existentially quantified variables.
-
-	__isl_give isl_set *isl_set_compute_divs(
-		__isl_take isl_set *set);
-	__isl_give isl_map *isl_map_compute_divs(
-		__isl_take isl_map *map);
-	__isl_give isl_union_set *isl_union_set_compute_divs(
-		__isl_take isl_union_set *uset);
-	__isl_give isl_union_map *isl_union_map_compute_divs(
-		__isl_take isl_union_map *umap);
-
-This explicit representation defines the existentially quantified
-variables as integer divisions of the other variables, possibly
-including earlier existentially quantified variables.
-An explicitly represented existentially quantified variable therefore
-has a unique value when the values of the other variables are known.
-If, furthermore, the same existentials, i.e., existentials
-with the same explicit representations, should appear in the
-same order in each of the disjuncts of a set or map, then the user should call
-either of the following functions.
-
-	__isl_give isl_set *isl_set_align_divs(
-		__isl_take isl_set *set);
-	__isl_give isl_map *isl_map_align_divs(
-		__isl_take isl_map *map);
-
-Alternatively, the existentially quantified variables can be removed
-using the following functions, which compute an overapproximation.
-
-	__isl_give isl_basic_set *isl_basic_set_remove_divs(
-		__isl_take isl_basic_set *bset);
-	__isl_give isl_basic_map *isl_basic_map_remove_divs(

-	__isl_give isl_set *isl_set_remove_divs(
-		__isl_take isl_set *set);
-	__isl_give isl_map *isl_map_remove_divs(
-		__isl_take isl_map *map);
-
-To iterate over all the sets or maps in a union set or map, use
-
-	int isl_union_set_foreach_set(__isl_keep isl_union_set *uset,
-		int (*fn)(__isl_take isl_set *set, void *user),
-		void *user);
-	int isl_union_map_foreach_map(__isl_keep isl_union_map *umap,

-
-	int isl_union_set_n_set(__isl_keep isl_union_set *uset);
-	int isl_union_map_n_map(__isl_keep isl_union_map *umap);
-
-To extract the set or map from a union with a given dimension
-specification, use
-
-	__isl_give isl_set *isl_union_set_extract_set(
-		__isl_keep isl_union_set *uset,
-		__isl_take isl_dim *dim);
-	__isl_give isl_map *isl_union_map_extract_map(

-
-To iterate over all the basic sets or maps in a set or map, use
-
-	int isl_set_foreach_basic_set(__isl_keep isl_set *set,

-		void *user);
-	int isl_map_foreach_basic_map(__isl_keep isl_map *map,
-		int (*fn)(__isl_take isl_basic_map *bmap, void *user),
-		void *user);
-
-The callback function C<fn> should return 0 if successful and
--1 if an error occurs.  In the latter case, or if any other error
-occurs, the above functions will return -1.
-
-It should be noted that C<isl> does not guarantee that
-the basic sets or maps passed to C<fn> are disjoint.
-If this is required, then the user should call one of
-the following functions first.
-
-	__isl_give isl_set *isl_set_make_disjoint(
-		__isl_take isl_set *set);
-	__isl_give isl_map *isl_map_make_disjoint(
-		__isl_take isl_map *map);
-
-The number of basic sets in a set can be obtained
-from
-
-	int isl_set_n_basic_set(__isl_keep isl_set *set);

-		int (*fn)(__isl_take isl_constraint *c, void *user),

-	void isl_constraint_free(struct isl_constraint *c);
-
-Again, the callback function C<fn> should return 0 if successful and
--1 if an error occurs.  In the latter case, or if any other error
-occurs, the above functions will return -1.
-The constraint C<c> represents either an equality or an inequality.
-Use the following function to find out whether a constraint
-represents an equality.  If not, it represents an inequality.
-
-	int isl_constraint_is_equality(
-		__isl_keep isl_constraint *constraint);
-
-The coefficients of the constraints can be inspected using

-	int isl_constraint_involves_dims(
-		__isl_keep isl_constraint *constraint,
-		enum isl_dim_type type, unsigned first, unsigned n);
-
-The explicit representations of the existentially quantified
-variables can be inspected using the following functions.
-Note that the user is only allowed to use these functions
-if the inspected set or map is the result of a call
-to C<isl_set_compute_divs> or C<isl_map_compute_divs>.
-
-	__isl_give isl_div *isl_constraint_div(

-
-Points are elements of a set.  They can be used to construct
-simple sets (boxes) or they can be used to represent the
-individual elements of a set.
-The zero point (the origin) can be created using
-
-	__isl_give isl_point *isl_point_zero(__isl_take isl_dim *dim);
-

-using

-
-Other properties can be obtained using

-Points can be copied or freed using
-
-	__isl_give isl_point *isl_point_copy(

-	void isl_point_free(__isl_take isl_point *pnt);
-
-A singleton set can be created from a point using

-
-The function C<fn> is called for each integer point in

-=head2 Piecewise Quasipolynomials
-
-A piecewise quasipolynomial is a particular kind of function that maps
-a parametric point to a rational value.
-More specifically, a quasipolynomial is a polynomial expression in greatest
-integer parts of affine expressions of parameters and variables.
-A piecewise quasipolynomial is a subdivision of a given parametric
-domain into disjoint cells with a quasipolynomial associated to
-each cell.  The value of the piecewise quasipolynomial at a given
-point is the value of the quasipolynomial associated to the cell
-that contains the point.  Outside of the union of cells,
-the value is assumed to be zero.
-For example, the piecewise quasipolynomial
-
-	[n] -> { [x] -> ((1 + n) - x) : x <= n and x >= 0 }
-
-maps C<x> to C<1 + n - x> for values of C<x> between C<0> and C<n>.
-A given piecewise quasipolynomial has a fixed domain dimension.
-Union piecewise quasipolynomials are used to contain piecewise quasipolynomials
-defined over different domains.
-Piecewise quasipolynomials are mainly used by the C<barvinok>
-library for representing the number of elements in a parametric set or map.
-For example, the piecewise quasipolynomial above represents
-the number of points in the map
-
-	[n] -> { [x] -> [y] : x,y >= 0 and 0 <= x + y <= n }
-
-=head3 Printing (Piecewise) Quasipolynomials

-
-The output format of the printer
-needs to be set to either C<ISL_FORMAT_ISL> or C<ISL_FORMAT_C>.
-For C<isl_printer_print_union_pw_qpolynomial>, only C<ISL_FORMAT_ISL>
-is supported.
-In case of printing in C<ISL_FORMAT_C>, the user may want
-to set the names of all dimensions
-
-	__isl_give isl_qpolynomial *isl_qpolynomial_set_dim_name(

-
-=head3 Creating New (Piecewise) Quasipolynomials

-
-The zero piecewise quasipolynomial or a piecewise quasipolynomial
-with a single cell can be created using the following functions.
-Multiple of these single cell piecewise quasipolynomials can
-be combined to create more complicated piecewise quasipolynomials.
-
-	__isl_give isl_pw_qpolynomial *isl_pw_qpolynomial_zero(
-		__isl_take isl_dim *dim);
-	__isl_give isl_pw_qpolynomial *isl_pw_qpolynomial_alloc(

-
-Quasipolynomials can be copied and freed again using the following
-functions.
-
-	__isl_give isl_qpolynomial *isl_qpolynomial_copy(

-
-=head3 Inspecting (Piecewise) Quasipolynomials
-
-To iterate over all piecewise quasipolynomials in a union
-piecewise quasipolynomial, use the following function
-
-	int isl_union_pw_qpolynomial_foreach_pw_qpolynomial(
-		__isl_keep isl_union_pw_qpolynomial *upwqp,
-		int (*fn)(__isl_take isl_pw_qpolynomial *pwqp, void *user),
-		void *user);
-
-To extract the piecewise quasipolynomial from a union with a given dimension
-specification, use
-
-	__isl_give isl_pw_qpolynomial *
-	isl_union_pw_qpolynomial_extract_pw_qpolynomial(
-		__isl_keep isl_union_pw_qpolynomial *upwqp,
-		__isl_take isl_dim *dim);
-
-To iterate over the cells in a piecewise quasipolynomial,
-use either of the following two functions
-
-	int isl_pw_qpolynomial_foreach_piece(
-		__isl_keep isl_pw_qpolynomial *pwqp,
-		int (*fn)(__isl_take isl_set *set,
-			  __isl_take isl_qpolynomial *qp,
-			  void *user), void *user);
-	int isl_pw_qpolynomial_foreach_lifted_piece(
-		__isl_keep isl_pw_qpolynomial *pwqp,
-		int (*fn)(__isl_take isl_set *set,
-			  __isl_take isl_qpolynomial *qp,
-			  void *user), void *user);
-
-As usual, the function C<fn> should return C<0> on success
-and C<-1> on failure.  The difference between
-C<isl_pw_qpolynomial_foreach_piece> and
-C<isl_pw_qpolynomial_foreach_lifted_piece> is that
-C<isl_pw_qpolynomial_foreach_lifted_piece> will first
-compute unique representations for all existentially quantified
-variables and then turn these existentially quantified variables
-into extra set variables, adapting the associated quasipolynomial
-accordingly.  This means that the C<set> passed to C<fn>
-will not have any existentially quantified variables, but that
-the dimensions of the sets may be different for different
-invocations of C<fn>.
-
-To iterate over all terms in a quasipolynomial,
-use
-
-	int isl_qpolynomial_foreach_term(
-		__isl_keep isl_qpolynomial *qp,
-		int (*fn)(__isl_take isl_term *term,
-			  void *user), void *user);
-
-The terms themselves can be inspected and freed using
-these functions
-
-	unsigned isl_term_dim(__isl_keep isl_term *term,
-		enum isl_dim_type type);
-	void isl_term_get_num(__isl_keep isl_term *term,
-		isl_int *n);
-	void isl_term_get_den(__isl_keep isl_term *term,
-		isl_int *d);
-	int isl_term_get_exp(__isl_keep isl_term *term,
-		enum isl_dim_type type, unsigned pos);
-	__isl_give isl_div *isl_term_get_div(
-		__isl_keep isl_term *term, unsigned pos);
-	void isl_term_free(__isl_take isl_term *term);
-
-Each term is a product of parameters, set variables and
-integer divisions.  The function C<isl_term_get_exp>
-returns the exponent of a given dimensions in the given term.
-The C<isl_int>s in the arguments of C<isl_term_get_num>
-and C<isl_term_get_den> need to have been initialized
-using C<isl_int_init> before calling these functions.
-
-=head3 Properties of (Piecewise) Quasipolynomials
-
-To check whether a quasipolynomial is actually a constant,
-use the following function.
-
-	int isl_qpolynomial_is_cst(__isl_keep isl_qpolynomial *qp,
-		isl_int *n, isl_int *d);
-
-If C<qp> is a constant and if C<n> and C<d> are not C<NULL>
-then the numerator and denominator of the constant
-are returned in C<*n> and C<*d>, respectively.

-=head2 Bounds on Piecewise Quasipolynomials and Piecewise Quasipolynomial Reductions
-
-A piecewise quasipolynomial reduction is a piecewise
-reduction (or fold) of quasipolynomials.
-In particular, the reduction can be maximum or a minimum.
-The objects are mainly used to represent the result of
-an upper or lower bound on a quasipolynomial over its domain,
-i.e., as the result of the following function.
-
-	__isl_give isl_pw_qpolynomial_fold *isl_pw_qpolynomial_bound(

-		__isl_take isl_union_pw_qpolynomial *upwqp,
-		enum isl_fold type, int *tight);
-
-The C<type> argument may be either C<isl_fold_min> or C<isl_fold_max>.
-If C<tight> is not C<NULL>, then C<*tight> is set to C<1>
-is the returned bound is known be tight, i.e., for each value
-of the parameters there is at least
-one element in the domain that reaches the bound.
-If the domain of C<pwqp> is not wrapping, then the bound is computed
-over all elements in that domain and the result has a purely parametric
-domain.  If the domain of C<pwqp> is wrapping, then the bound is
-computed over the range of the wrapped relation.  The domain of the
-wrapped relation becomes the domain of the result.
-
-A (piecewise) quasipolynomial reduction can be copied or freed using the
-following functions.

-=head2 Dependence Analysis
-
-C<isl> contains specialized functionality for performing
-array dataflow analysis.  That is, given a I<sink> access relation
-and a collection of possible I<source> access relations,
-C<isl> can compute relations that describe
-for each iteration of the sink access, which iteration
-of which of the source access relations was the last
-to access the same data element before the given iteration
-of the sink access.
-To compute standard flow dependences, the sink should be
-a read, while the sources should be writes.
-If any of the source accesses are marked as being I<may>
-accesses, then there will be a dependence to the last
-I<must> access B<and> to any I<may> access that follows
-this last I<must> access.
-In particular, if I<all> sources are I<may> accesses,
-then memory based dependence analysis is performed.
-If, on the other hand, all sources are I<must> accesses,
-then value based dependence analysis is performed.
-
-	#include <isl/flow.h>
-
-	typedef int (*isl_access_level_before)(void *first, void *second);
-
-	__isl_give isl_access_info *isl_access_info_alloc(
-		__isl_take isl_map *sink,
-		void *sink_user, isl_access_level_before fn,
-		int max_source);
-	__isl_give isl_access_info *isl_access_info_add_source(
-		__isl_take isl_access_info *acc,
-		__isl_take isl_map *source, int must,
-		void *source_user);
-	void isl_access_info_free(__isl_take isl_access_info *acc);
-
-	__isl_give isl_flow *isl_access_info_compute_flow(
-		__isl_take isl_access_info *acc);
-
-	int isl_flow_foreach(__isl_keep isl_flow *deps,
-		int (*fn)(__isl_take isl_map *dep, int must,
-			  void *dep_user, void *user),
-		void *user);
-	__isl_give isl_map *isl_flow_get_no_source(
-		__isl_keep isl_flow *deps, int must);
-	void isl_flow_free(__isl_take isl_flow *deps);
-
-The function C<isl_access_info_compute_flow> performs the actual
-dependence analysis.  The other functions are used to construct
-the input for this function or to read off the output.
-
-The input is collected in an C<isl_access_info>, which can
-be created through a call to C<isl_access_info_alloc>.
-The arguments to this functions are the sink access relation
-C<sink>, a token C<sink_user> used to identify the sink
-access to the user, a callback function for specifying the
-relative order of source and sink accesses, and the number
-of source access relations that will be added.
-The callback function has type C<int (*)(void *first, void *second)>.
-The function is called with two user supplied tokens identifying
-either a source or the sink and it should return the shared nesting
-level and the relative order of the two accesses.
-In particular, let I<n> be the number of loops shared by
-the two accesses.  If C<first> precedes C<second> textually,
-then the function should return I<2 * n + 1>; otherwise,
-it should return I<2 * n>.
-The sources can be added to the C<isl_access_info> by performing
-(at most) C<max_source> calls to C<isl_access_info_add_source>.
-C<must> indicates whether the source is a I<must> access
-or a I<may> access.  Note that a multi-valued access relation
-should only be marked I<must> if every iteration in the domain
-of the relation accesses I<all> elements in its image.
-The C<source_user> token is again used to identify
-the source access.  The range of the source access relation
-C<source> should have the same dimension as the range
-of the sink access relation.
-The C<isl_access_info_free> function should usually not be
-called explicitly, because it is called implicitly by
-C<isl_access_info_compute_flow>.
-
-The result of the dependence analysis is collected in an
-C<isl_flow>.  There may be elements of
-the sink access for which no preceding source access could be
-found or for which all preceding sources are I<may> accesses.
-The relations containing these elements can be obtained through
-calls to C<isl_flow_get_no_source>, the first with C<must> set
-and the second with C<must> unset.
-In the case of standard flow dependence analysis,
-with the sink a read and the sources I<must> writes,
-the first relation corresponds to the reads from uninitialized
-array elements and the second relation is empty.
-The actual flow dependences can be extracted using
-C<isl_flow_foreach>.  This function will call the user-specified
-callback function C<fn> for each B<non-empty> dependence between
-a source and the sink.  The callback function is called
-with four arguments, the actual flow dependence relation
-mapping source iterations to sink iterations, a boolean that
-indicates whether it is a I<must> or I<may> dependence, a token
-identifying the source and an additional C<void *> with value
-equal to the third argument of the C<isl_flow_foreach> call.
-A dependence is marked I<must> if it originates from a I<must>
-source and if it is not followed by any I<may> sources.
-
-After finishing with an C<isl_flow>, the user should call
-C<isl_flow_free> to free all associated memory.
-
-A higher-level interface to dependence analysis is provided
-by the following function.
-
-	#include <isl/flow.h>
-
-	int isl_union_map_compute_flow(__isl_take isl_union_map *sink,
-		__isl_take isl_union_map *must_source,
-		__isl_take isl_union_map *may_source,
-		__isl_take isl_union_map *schedule,
-		__isl_give isl_union_map **must_dep,
-		__isl_give isl_union_map **may_dep,
-		__isl_give isl_union_map **must_no_source,
-		__isl_give isl_union_map **may_no_source);
-
-The arrays are identified by the tuple names of the ranges
-of the accesses.  The iteration domains by the tuple names
-of the domains of the accesses and of the schedule.
-The relative order of the iteration domains is given by the
-schedule.  The relations returned through C<must_no_source>
-and C<may_no_source> are subsets of C<sink>.
-Any of C<must_dep>, C<may_dep>, C<must_no_source>
-or C<may_no_source> may be C<NULL>, but a C<NULL> value for
-any of the other arguments is treated as an error.
-
-=head2 Scheduling
-
-B<The functionality described in this section is fairly new
-and may be subject to change.>
-
-The following function can be used to compute a schedule
-for a union of domains.  The generated schedule respects
-all C<validity> dependences.  That is, all dependence distances
-over these dependences in the scheduled space are lexicographically
-positive.  The generated schedule schedule also tries to minimize
-the dependence distances over C<proximity> dependences.
-Moreover, it tries to obtain sequences (bands) of schedule dimensions
-for groups of domains where the dependence distances have only
-non-negative values.
-The algorithm used to construct the schedule is similar to that
-of C<Pluto>.
-
-	#include <isl/schedule.h>
-	__isl_give isl_schedule *isl_union_set_compute_schedule(
-		__isl_take isl_union_set *domain,
-		__isl_take isl_union_map *validity,
-		__isl_take isl_union_map *proximity);
-	void *isl_schedule_free(__isl_take isl_schedule *sched);
-
-A mapping from the domains to the scheduled space can be obtained
-from an C<isl_schedule> using the following function.
-
-	__isl_give isl_union_map *isl_schedule_get_map(
-		__isl_keep isl_schedule *sched);
-
-A representation of the schedule can be printed using
-	 
-	__isl_give isl_printer *isl_printer_print_schedule(
-		__isl_take isl_printer *p,
-		__isl_keep isl_schedule *schedule);
-
-A representation of the schedule as a forest of bands can be obtained
-using the following function.
-
-	__isl_give isl_band_list *isl_schedule_get_band_forest(
-		__isl_keep isl_schedule *schedule);
-
-The list can be manipulated as explained in L<"Lists">.
-The bands inside the list can be copied and freed using the following
-functions.
-
-	#include <isl/band.h>
-	__isl_give isl_band *isl_band_copy(
-		__isl_keep isl_band *band);
-	void *isl_band_free(__isl_take isl_band *band);
-
-Each band contains zero or more scheduling dimensions.
-These are referred to as the members of the band.
-The section of the schedule that corresponds to the band is
-referred to as the partial schedule of the band.
-For those nodes that participate in a band, the outer scheduling
-dimensions form the prefix schedule, while the inner scheduling
-dimensions form the suffix schedule.
-That is, if we take a cut of the band forest, then the union of
-the concatenations of the prefix, partial and suffix schedules of
-each band in the cut is equal to the entire schedule (modulo
-some possible padding at the end with zero scheduling dimensions).
-The properties of a band can be inspected using the following functions.
-
-	#include <isl/band.h>
-	isl_ctx *isl_band_get_ctx(__isl_keep isl_band *band);
-
-	int isl_band_has_children(__isl_keep isl_band *band);
-	__isl_give isl_band_list *isl_band_get_children(
-		__isl_keep isl_band *band);
-
-	__isl_give isl_union_map *isl_band_get_prefix_schedule(
-		__isl_keep isl_band *band);
-	__isl_give isl_union_map *isl_band_get_partial_schedule(
-		__isl_keep isl_band *band);
-	__isl_give isl_union_map *isl_band_get_suffix_schedule(
-		__isl_keep isl_band *band);
-
-	int isl_band_n_member(__isl_keep isl_band *band);
-	int isl_band_member_is_zero_distance(
-		__isl_keep isl_band *band, int pos);
-
-Note that a scheduling dimension is considered to be ``zero
-distance'' if it does not carry any proximity dependences
-within its band.
-That is, if the dependence distances of the proximity
-dependences are all zero in that direction (for fixed
-iterations of outer bands).
-
-A representation of the band can be printed using
-
-	#include <isl/band.h>
-	__isl_give isl_printer *isl_printer_print_band(
-		__isl_take isl_printer *p,
-		__isl_keep isl_band *band);
-
-=head2 Parametric Vertex Enumeration
-
-The parametric vertex enumeration described in this section
-is mainly intended to be used internally and by the C<barvinok>
-library.
-
-	#include <isl/vertices.h>
-	__isl_give isl_vertices *isl_basic_set_compute_vertices(
-		__isl_keep isl_basic_set *bset);
-
-The function C<isl_basic_set_compute_vertices> performs the
-actual computation of the parametric vertices and the chamber
-decomposition and store the result in an C<isl_vertices> object.
-This information can be queried by either iterating over all
-the vertices or iterating over all the chambers or cells
-and then iterating over all vertices that are active on the chamber.
-
-	int isl_vertices_foreach_vertex(
-		__isl_keep isl_vertices *vertices,
-		int (*fn)(__isl_take isl_vertex *vertex, void *user),
-		void *user);
-
-	int isl_vertices_foreach_cell(
-		__isl_keep isl_vertices *vertices,
-		int (*fn)(__isl_take isl_cell *cell, void *user),
-		void *user);
-	int isl_cell_foreach_vertex(__isl_keep isl_cell *cell,
-		int (*fn)(__isl_take isl_vertex *vertex, void *user),
-		void *user);
-
-Other operations that can be performed on an C<isl_vertices> object are
-the following.
-
-	isl_ctx *isl_vertices_get_ctx(
-		__isl_keep isl_vertices *vertices);
-	int isl_vertices_get_n_vertices(
-		__isl_keep isl_vertices *vertices);
-	void isl_vertices_free(__isl_take isl_vertices *vertices);
-
-Vertices can be inspected and destroyed using the following functions.
-
-	isl_ctx *isl_vertex_get_ctx(__isl_keep isl_vertex *vertex);
-	int isl_vertex_get_id(__isl_keep isl_vertex *vertex);
-	__isl_give isl_basic_set *isl_vertex_get_domain(
-		__isl_keep isl_vertex *vertex);
-	__isl_give isl_basic_set *isl_vertex_get_expr(
-		__isl_keep isl_vertex *vertex);
-	void isl_vertex_free(__isl_take isl_vertex *vertex);
-
-C<isl_vertex_get_expr> returns a singleton parametric set describing
-the vertex, while C<isl_vertex_get_domain> returns the activity domain
-of the vertex.
-Note that C<isl_vertex_get_domain> and C<isl_vertex_get_expr> return
-B<rational> basic sets, so they should mainly be used for inspection
-and should not be mixed with integer sets.
-
-Chambers can be inspected and destroyed using the following functions.
-
-	isl_ctx *isl_cell_get_ctx(__isl_keep isl_cell *cell);
-	__isl_give isl_basic_set *isl_cell_get_domain(
-		__isl_keep isl_cell *cell);
-	void isl_cell_free(__isl_take isl_cell *cell);
-
-=head1 Applications
-
-Although C<isl> is mainly meant to be used as a library,
-it also contains some basic applications that use some
-of the functionality of C<isl>.
-The input may be specified in either the L<isl format>
-or the L<PolyLib format>.
-
-=head2 C<isl_polyhedron_sample>
-
-C<isl_polyhedron_sample> takes a polyhedron as input and prints
-an integer element of the polyhedron, if there is any.
-The first column in the output is the denominator and is always
-equal to 1.  If the polyhedron contains no integer points,
-then a vector of length zero is printed.
-
-=head2 C<isl_pip>
-
-C<isl_pip> takes the same input as the C<example> program
-from the C<piplib> distribution, i.e., a set of constraints
-on the parameters, a line containing only -1 and finally a set
-of constraints on a parametric polyhedron.
-The coefficients of the parameters appear in the last columns
-(but before the final constant column).
-The output is the lexicographic minimum of the parametric polyhedron.
-As C<isl> currently does not have its own output format, the output
-is just a dump of the internal state.
-
-=head2 C<isl_polyhedron_minimize>
-
-C<isl_polyhedron_minimize> computes the minimum of some linear
-or affine objective function over the integer points in a polyhedron.
-If an affine objective function
-is given, then the constant should appear in the last column.
-
-=head2 C<isl_polytope_scan>
-
-Given a polytope, C<isl_polytope_scan> prints
-all integer points in the polytope.

- *	redundant	the constraint is redundant in its own
- *			basic map and should be ignore and removed
- *			in the end

- *			to an equality of the other basic map
- *	adj_ineq	the given constraint is adjacent (on the outside)
- *			to an inequality of the other basic map
- *
- * We consider seven cases in which we can replace the pair by a single
- * basic map.  We ignore all "redundant" constraints.
- *
- *	1. all constraints of one basic map are valid
- *		=> the other basic map is a subset and can be removed
- *
- *	2. all constraints of both basic maps are either "valid" or "cut"
- *	   and the facets corresponding to the "cut" constraints
- *	   of one of the basic maps lies entirely inside the other basic map
- *		=> the pair can be replaced by a basic map consisting
- *		   of the valid constraints in both basic maps
- *
- *	3. there is a single pair of adjacent inequalities
- *	   (all other constraints are "valid")
- *		=> the pair can be replaced by a basic map consisting
- *		   of the valid constraints in both basic maps
- *
- *	4. there is a single adjacent pair of an inequality and an equality,
- *	   the other constraints of the basic map containing the inequality are
- *	   "valid".  Moreover, if the inequality the basic map is relaxed
- *	   and then turned into an equality, then resulting facet lies
- *	   entirely inside the other basic map
- *		=> the pair can be replaced by the basic map containing
- *		   the inequality, with the inequality relaxed.
- *
- *	5. there is a single adjacent pair of an inequality and an equality,
- *	   the other constraints of the basic map containing the inequality are
- *	   "valid".  Moreover, the facets corresponding to both
- *	   the inequality and the equality can be wrapped around their
- *	   ridges to include the other basic map
- *		=> the pair can be replaced by a basic map consisting
- *		   of the valid constraints in both basic maps together
- *		   with all wrapping constraints
- *
- *	6. one of the basic maps extends beyond the other by at most one.
- *	   Moreover, the facets corresponding to the cut constraints and
- *	   the pieces of the other basic map at offset one from these cut
- *	   constraints can be wrapped around their ridges to include
- *	   the union of the two basic maps
- *		=> the pair can be replaced by a basic map consisting
- *		   of the valid constraints in both basic maps together
- *		   with all wrapping constraints
- *
- *	7. the two basic maps live in adjacent hyperplanes.  In principle
- *	   such sets can always be combined through wrapping, but we impose
- *	   that there is only one such pair, to avoid overeager coalescing.
- *
- * Throughout the computation, we maintain a collection of tableaus
- * corresponding to the basic maps.  When the basic maps are dropped
- * or combined, the tableaus are modified accordingly.

-/* Compute the convex hull of a pair of basic sets without any parameters or

- *
- * We turn this problem into the computation of a convex hull of a pair
- * _bounded_ polyhedra by "changing the direction of the homogeneous
- * dimension".  This idea is due to Matthias Koeppe.
- *
- * Consider the cones in homogeneous space that correspond to the
- * input polyhedra.  The rays of these cones are also rays of the
- * polyhedra if the coordinate that corresponds to the homogeneous
- * dimension is zero.  That is, if the inner product of the rays
- * with the homogeneous direction is zero.
- * The cones in the homogeneous space can also be considered to
- * correspond to other pairs of polyhedra by chosing a different
- * homogeneous direction.  To ensure that both of these polyhedra
- * are bounded, we need to make sure that all rays of the cones
- * correspond to vertices and not to rays.
- * Let s be a direction such that <s, r> > 0 for all rays r of both cones.
- * Then using s as a homogeneous direction, we obtain a pair of polytopes.
- * The vector s is computed in valid_direction.
- *
- * Note that we need to consider _all_ rays of the cones and not just
- * the rays that correspond to rays in the polyhedra.  If we were to
- * only consider those rays and turn them into vertices, then we
- * may inadvertently turn some vertices into rays.
- *
- * The standard homogeneous direction is the unit vector in the 0th coordinate.
- * We therefore transform the two polyhedra such that the selected
- * direction is mapped onto this standard direction and then proceed
- * with the normal computation.
- * Let S be a non-singular square matrix with s as its first row,
- * then we want to map the polyhedra to the space
- *
- *	[ y' ]     [ y ]		[ y ]          [ y' ]
- *	[ x' ] = S [ x ]	i.e.,	[ x ] = S^{-1} [ x' ]
- *
- * We take S to be the unimodular completion of s to limit the growth
- * of the coefficients in the following computations.
- *
- * Let b_i + A_i x >= 0 be the constraints of polyhedron i.
- * We first move to the homogeneous dimension
- *
- *	b_i y + A_i x >= 0		[ b_i A_i ] [ y ]    [ 0 ]
- *	    y         >= 0	or	[  1   0  ] [ x ] >= [ 0 ]
- *
- * Then we change directoin
- *
- *	[ b_i A_i ]        [ y' ]		              [ y' ]
- *	[  1   0  ] S^{-1} [ x' ] >= 0	or	[ b_i' A_i' ] [ x' ] >= 0
- *
- * Then we compute the convex hull of the polytopes b_i' + A_i' x' >= 0
- * resulting in b' + A' x' >= 0, which we then convert back
- *
- *	            [ y ]		        [ y ]
- *	[ b' A' ] S [ x ] >= 0	or	[ b A ] [ x ] >= 0
- *
- * The polyhedron b + A x >= 0 is then the convex hull of the input polyhedra.

- * That is we want to compute G such that
- *
- *		y = G y''
- *
- * with y'' integer, describes the set of solutions.
- *
- * We first remove the common factors of each row.
- * In particular if gcd(A_i,d_i) != 1, then we divide the whole
- * row i (including d_i) by this common factor.  If afterwards gcd(A_i) != 1,
- * then we divide this row of A by the common factor, unless gcd(A_i) = 0.
- * In the later case, we simply drop the row (in both A and d).
- *
- * If there are no rows left in A, then G is the identity matrix. Otherwise,
- * for each row i, we now determine the lattice of integer vectors
- * that satisfies this row.  Let U_i be the unimodular extension of the
- * row A_i.  This unimodular extension exists because gcd(A_i) = 1.
- * The first component of
- *
- *		y' = U_i y
- *
- * needs to be a multiple of d_i.  Let y' = diag(d_i, 1, ..., 1) y''.
- * Then,
- *
- *		y = U_i^{-1} diag(d_i, 1, ..., 1) y''
- *
- * for arbitrary integer vectors y''.  That is, y belongs to the lattice
- * generated by the columns of L_i = U_i^{-1} diag(d_i, 1, ..., 1).
- * If there is only one row, then G = L_1.
- *
- * If there is more than one row left, we need to compute the intersection
- * of the lattices.  That is, we need to compute an L such that
- *
- *		L = L_i L_i'	for all i
- *
- * with L_i' some integer matrices.  Let A be constructed as follows
- *
- *		A = [ L_1^{-T} L_2^{-T} ... L_k^{-T} ]
- *
- * and computed the Hermite Normal Form of A = [ H 0 ] U
- * Then,
- *
- *		L_i^{-T} = H U_{1,i}
- *
- * or
- *
- *		H^{-T} = L_i U_{1,i}^T
- *
- * In other words G = L = H^{-T}.
- * To ensure that G is lower triangular, we compute and use its Hermite
- * normal form.
- *
- * The affine transformation matrix returned is then
- *
- *		[  1   0  ]
- *		[ y_0  G  ]
- *
- * as any y = y_0 + G y' with y' integer is a solution to the original
- * modulo constraints.

- * The outermost statement level is 1, the first loop level is 2, etc...
- * The algorithm basically does the following:
- * for all levels l of the read access from innermost to outermost
- *	for all sources w that may precede the sink access at that level
- *	    compute the last iteration of the source that precedes the sink access
- *					    at that level
- *	    add result to possible last accesses at level l of source w
- *	    for all sources w2 that we haven't considered yet at this level that may
- *					    also precede the sink access
- *		for all levels l2 of w from l to innermost
- *		    for all possible last accesses dep of w at l
- *			compute last iteration of w2 between the source and sink
- *								of dep
- *			add result to possible last accesses at level l of write w2
- *			and replace possible last accesses dep by the remainder
- *
- *
- * The above algorithm is applied to the must access.  During the course
- * of the algorithm, we keep track of sink iterations that still
- * need to be considered.  These iterations are split into those that
- * haven't been matched to any source access (mustdo) and those that have only
- * been matched to may accesses (maydo).
- * At the end of each level, we also consider the may accesses.
- * In particular, we consider may accesses that precede the remaining
- * sink iterations, moving elements from mustdo to maydo when appropriate,
- * and may accesses that occur between a must source and a sink of any 
- * dependences found at the current level, turning must dependences into
- * may dependences when appropriate.

- * with G a lower-triangular matrix with all elements below the diagonal
- * non-negative and smaller than the diagonal element on the same row.
- * We first normalize x_0 by making the same property hold in the affine
- * T matrix.
- * The rows i of G with a 1 on the diagonal do not impose any modulo
- * constraint and simply express x_i = x'_i.
- * For each of the remaining rows i, we introduce a div and a corresponding
- * equality.  In particular
- *
- *	g_ii e_j = x_i - g_i(x')
- *
- * where each x'_k is replaced either by x_k (if g_kk = 1) or the
- * corresponding div (if g_kk != 1).
- *
- * If there are any equalities not involving any div, then we
- * first apply a variable compression on the variables x:
- *
- *	x = C x''	x'' = C_2 x
- *
- * and perform the above parameter compression on A C instead of on A.
- * The resulting compression is then of the form
- *
- *	x'' = T(x') = x_0 + G x'
- *
- * and in constructing the new divs and the corresponding equalities,

- *
- * This function is a slight generalization of isl_mat_variable_compression
- * in that it allows the input to be parametric and that it allows for the
- * compression of either parameters or set variables.
- *
- * We first select the equalities of interest, that is those that involve

- * Denote those equalities as
- *
- *		-C(p) + M x = 0
- *
- * where C(p) depends on the parameters if type == isl_dim_set and
- * is a constant if type == isl_dim_param.
- *
- * First compute the (left) Hermite normal form of M,
- *
- *		M [U1 U2] = M U = H = [H1 0]
- * or
- *		              M = H Q = [H1 0] [Q1]

- * Define the transformed variables as
- *
- *		x = [U1 U2] [ x1' ] = [U1 U2] [Q1] x
- *		            [ x2' ]           [Q2]
- *
- * The equalities then become
- *
- *		-C(p) + H1 x1' = 0   or   x1' = H1^{-1} C(p) = C'(p)
- *
- * If the denominator of the constant term does not divide the
- * the common denominator of the parametric terms, then every
- * integer point is mapped to a non-integer point and then the original set has no
- * integer solutions (since the x' are a unimodular transformation
- * of the x).  In this case, an empty morphism is returned.
- * Otherwise, the transformation is given by
- *
- *		x = U1 H1^{-1} C(p) + U2 x2'
- *
- * The inverse transformation is simply

- *		x2' = Q2 x
- *

-/* Order size using quicksort.  This implementation incorporates

-
-   1. Non-recursive, using an explicit stack of pointer that store the
-      next array partition to sort.  To save time, this maximum amount
-      of space required to store an array of SIZE_MAX is allocated on the
-      stack.  Assuming a 32-bit (64 bit) integer for size_t, this needs
-      only 32 * sizeof(stack_node) == 256 bytes (for 64 bit: 1024 bytes).
-      Pretty cheap, actually.
-
-   2. Chose the pivot element using a median-of-three decision tree.
-      This reduces the probability of selecting a bad pivot value and
-      eliminates certain extraneous comparisons.
-
-   3. Only quicksorts TOTAL_ELEMS / MAX_THRESH partitions, leaving
-      insertion sort to order the MAX_THRESH items within each partition.
-      This is a big win, since insertion sort is faster for small, mostly
-      sorted array segments.
-
-   4. The larger of the two sub-partitions is always pushed onto the
-      stack first, with the algorithm then concentrating on the
-      smaller partition.  This *guarantees* no more than log (total_elems)
-      stack size is needed (actually O(1) in this case)!  */

- * by the calling function.  Otherwise an initial basis that exploits
- * the equalities in the tableau is created.
- * tab->n_zero is currently ignored and is clobbered by this function.
- *
- * The tableau is allowed to have unbounded direction, but then
- * the calling function needs to set an initial basis, with the
- * unbounded directions last and with tab->n_unbounded set
- * to the number of unbounded directions.
- * Furthermore, the calling functions needs to add shifted copies
- * of all constraints involving unbounded directions to ensure
- * that any feasible rational value in these directions can be rounded
- * up to yield a feasible integer value.
- * In particular, let B define the given basis x' = B x
- * and let T be the inverse of B, i.e., X = T x'.
- * Let a x + c >= 0 be a constraint of the set represented by the tableau,
- * or a T x' + c >= 0 in terms of the given basis.  Assume that
- * the bounded directions have an integer value, then we can safely
- * round up the values for the unbounded directions if we make sure
- * that x' not only satisfies the original constraint, but also
- * the constraint "a T x' + c + s >= 0" with s the sum of all
- * negative values in the last n_unbounded entries of "a T".
- * The calling function therefore needs to add the constraint
- * a x + c + s >= 0.  The current function then scans the first
- * directions for an integer value and once those have been found,
- * it can compute "T ceil(B x)" to yield an integer point in the set.
- * Note that during the search, the first rows of B may be changed
- * by a basis reduction, but the last n_unbounded rows of B remain
- * unaltered and are also not mixed into the first rows.
- *
- * The search is implemented iteratively.  "level" identifies the current
- * basis vector.  "init" is true if we want the first value at the current
- * level and false if we want the next value.
- *
- * The initial basis is the identity matrix.  If the range in some direction
- * contains more than one integer value, we perform basis reduction based
- * on the value of ctx->opt->gbr
- *	- ISL_GBR_NEVER:	never perform basis reduction
- *	- ISL_GBR_ONCE:		only perform basis reduction the first
- *				time such a range is encountered
- *	- ISL_GBR_ALWAYS:	always perform basis reduction when
- *				such a range is encountered
- *
- * When ctx->opt->gbr is set to ISL_GBR_ALWAYS, then we allow the basis
- * reduction computation to return early.  That is, as soon as it

-/* The tableau maintains equality relations.

- * The "value" of an inequality constraint is the value of the corresponding
- * slack variable.
- * The "row_var" and "col_var" arrays map column and row indices
- * to indices in the "var" and "con" arrays.  The elements of these
- * arrays maintain extra information about the variables and the constraints.
- * Each row expresses the corresponding row variable as an affine expression
- * of the column variables.
- * The first two columns in the matrix contain the common denominator of
- * the row and the numerator of the constant term.
- * If "M" is set, then the third column represents the "big parameter".
- * The third (M = 0) or fourth (M = 1) column
- * in the matrix is called column 0 with respect to the col_var array.
- * The sample value of the tableau is the value that assigns zero
- * to all the column variables and the constant term of each affine
- * expression to the corresponding row variable.
- * The operations on the tableau maintain the property that the sample
- * value satisfies the non-negativity constraints (usually on the slack
- * variables).
- *
- * The big parameter represents an arbitrarily big (and divisible)
- * positive number.  If present, then the sign of a row is determined
- * lexicographically, with the sign of the big parameter coefficient
- * considered first.  The big parameter is only used while
- * solving PILP problems.
- *
- * The first n_dead column variables have their values fixed to zero.
- * The corresponding tab_vars are flagged "is_zero".
- * Some of the rows that have have zero coefficients in all but
- * the dead columns are also flagged "is_zero".
- *
- * The first n_redundant rows correspond to inequality constraints
- * that are always satisfied for any value satisfying the non-redundant
- * rows.  The corresponding tab_vars are flagged "is_redundant".
- * A row variable that is flagged "is_zero" is also flagged "is_redundant"
- * since the constraint has been reduced to 0 = 0 and is therefore always
- * satisfied.
- *
- * There are "n_var" variables in total.  The first "n_param" of these
- * are called parameters and the last "n_div" of these are called divs.
- * The basic tableau operations makes no distinction between different
- * kinds of variables.  These special variables are only used while
- * solving PILP problems.
- *
- * Dead columns and redundant rows are detected on the fly.
- * However, the basic operations do not ensure that all dead columns
- * or all redundant rows are detected.
- * isl_tab_detect_implicit_equalities and isl_tab_detect_redundant can be used
- * to perform and exhaustive search for dead columns and redundant rows.
- *
- * The samples matrix contains "n_sample" integer points that have at some
- * point been elements satisfying the tableau.  The first "n_outside"
- * of them no longer satisfy the tableau.  They are kept because they
- * can be reinstated during rollback when the constraint that cut them
- * out is removed.  These samples are only maintained for the context
- * tableau while solving PILP problems.

- * in a row that increases the constant term of the row holding the
- * constraint, making sure the sample solution remains feasible
- * for all the constraints it already satisfied.
- * Here, we always pivot in the row holding the constraint,
- * choosing a column that induces the lexicographically smallest
- * increment to the sample solution.
- *
- * By starting out from a sample value that is lexicographically
- * smaller than any integer point in the problem space, the first
- * feasible integer sample point we find will also be the lexicographically
- * smallest.  If all variables can be assumed to be non-negative,
- * then the initial sample value may be chosen equal to zero.
- * However, we will not make this assumption.  Instead, we apply
- * the "big parameter" trick.  Any variable x is then not directly
- * used in the tableau, but instead it is represented by another
- * variable x' = M + x, where M is an arbitrarily large (positive)
- * value.  x' is therefore always non-negative, whatever the value of x.
- * Taking as initial sample value x' = 0 corresponds to x = -M,
- * which is always smaller than any possible value of x.
- *
- * The big parameter trick is used in the main tableau and
- * also in the context tableau if isl_context_lex is used.
- * In this case, each tableaus has its own big parameter.
- * Before doing any real work, we check if all the parameters
- * happen to be non-negative.  If so, we drop the column corresponding
- * to M from the initial context tableau.
- * If isl_context_gbr is used, then the big parameter trick is only
- * used in the main tableau.

- *	- the parametric constant may be equal to that of another row

- *	  "any".  If it had been "neg" then we would have pivoted before.
- *
- * If none of these cases hold, we check the value of the row for each

- *	>0 ?	     Y      N	 Y     N
- *		    any    neg  any   neg
- *
- * There is no special sign for "zero", because we can usually treat zero
- * as either non-negative or non-positive, whatever works out best.
- * However, if the row is "critical", meaning that pivoting is impossible
- * then we don't want to limp zero with the non-positive case, because
- * then we we would lose the solution for those values of the parameters
- * where the value of the row is zero.  Instead, we treat 0 as non-negative
- * ensuring a split if the row can attain both zero and negative values.
- * The same happens when the original constraint was one that could not
- * be satisfied with equality by any integer values of the parameters.
- * In this case, we normalize the constraint, but then a value of zero
- * for the normalized constraint is actually a positive value for the
- * original constraint, so again we need to treat zero as non-negative.
- * In both these cases, we have the following decision tree instead:
- *
- *	all non-negative		->	pos
- *	all negative			->	neg
- *	both negative and non-negative	->	all
- *
- *	samples	       neg	          	       pos

- * be infeasible.  Some pivots may need to be performed for only some
- * feasible values of the context tableau.  If so, the context tableau
- * is split into a part where the pivot is needed and a part where it is not.
- *
- * Whenever we enter the main loop, the main tableau is such that no
- * "obvious" pivots need to be performed on it, where "obvious" means
- * that the given row can be seen to be negative without looking at
- * the context tableau.  In particular, for non-parametric problems,
- * no pivots need to be performed on the main tableau.
- * The caller of find_solutions is responsible for making this property
- * hold prior to the first iteration of the loop, while restore_lexmin
- * is called before every other iteration.
- *
- * Inside the main loop, we first examine the signs of the rows of
- * the main tableau within the context of the context tableau.
- * If we find a row that is always non-positive for all values of
- * the parameters satisfying the context tableau and negative for at
- * least one value of the parameters, we perform the appropriate pivot
- * and start over.  An exception is the case where no pivot can be
- * performed on the row.  In this case, we require that the sign of
- * the row is negative for all values of the parameters (rather than just
- * non-positive).  This special case is handled inside row_sign, which
- * will say that the row can have any sign if it determines that it can
- * attain both negative and zero values.
- *
- * If we can't find a row that always requires a pivot, but we can find
- * one or more rows that require a pivot for some values of the parameters
- * (i.e., the row can attain both positive and negative signs), then we split
- * the context tableau into two parts, one where we force the sign to be
- * non-negative and one where we force is to be negative.
- * The non-negative part is handled by a recursive call (through find_in_pos).
- * Upon returning from this call, we continue with the negative part and
- * perform the required pivot.
- *
- * If no such rows can be found, all rows are non-negative and we have
- * found a (rational) feasible point.  If we only wanted a rational point
- * then we are done.
- * Otherwise, we check if all values of the sample point of the tableau
- * are integral for the variables.  If so, we have found the minimal
- * integral point and we are done.
- * If the sample point is not integral, then we need to make a distinction
- * based on whether the constant term is non-integral or the coefficients
- * of the parameters.  Furthermore, in order to decide how to handle
- * the non-integrality, we also need to know whether the coefficients
- * of the other columns in the tableau are integral.  This leads
- * to the following table.  The first two rows do not correspond
- * to a non-integral sample point and are only mentioned for completeness.
- *
- *	constant	parameters	other
- *
- *	int		int		int	|
- *	int		int		rat	| -> no problem
- *
- *	rat		int		int	  -> fail
- *
- *	rat		int		rat	  -> cut
- *
- *	int		rat		rat	|
- *	rat		rat		rat	| -> parametric cut
- *
- *	int		rat		int	|
- *	rat		rat		int	| -> split context
- *
- * If the parametric constant is completely integral, then there is nothing
- * to be done.  If the constant term is non-integral, but all the other
- * coefficient are integral, then there is nothing that can be done
- * and the tableau has no integral solution.
- * If, on the other hand, one or more of the other columns have rational
- * coefficients, but the parameter coefficients are all integral, then
- * we can perform a regular (non-parametric) cut.
- * Finally, if there is any parameter coefficient that is non-integral,
- * then we need to involve the context tableau.  There are two cases here.
- * If at least one other column has a rational coefficient, then we
- * can perform a parametric cut in the main tableau by adding a new
- * integer division in the context tableau.
- * If all other columns have integral coefficients, then we need to
- * enforce that the rational combination of parameters (c + \sum a_i y_i)/m
- * is always integral.  We do this by introducing an integer division
- * q = floor((c + \sum a_i y_i)/m) and stipulating that its argument should
- * always be integral in the context tableau, i.e., m q = c + \sum a_i y_i.
- * Since q is expressed in the tableau as
- *	c + \sum a_i y_i - m q >= 0
- *	-c - \sum a_i y_i + m q + m - 1 >= 0
- * it is sufficient to add the inequality
- *	-c - \sum a_i y_i + m q >= 0
- * In the part of the context where this inequality does not hold, the
- * main tableau is marked as being empty.

- * by "bset" given the parametric vertices and their activity domains.
- *
- * We are only interested in full-dimensional chambers.
- * Each of these chambers is the intersection of the activity domains of
- * one or more vertices and the union of all chambers is equal to the
- * projection of the entire parametric polytope onto the parameter space.
- *
- * We first create an initial chamber by intersecting as many activity
- * domains as possible without ending up with an empty or lower-dimensional
- * set.  As a minor optimization, we only consider those activity domains
- * that contain some arbitrary point.
- *
- * For each of interior facets of the chamber, we construct a todo item,
- * containing the facet and a constraint containing the other side of the facet,
- * for constructing the chamber on the other side.
- * While their are any todo items left, we pick a todo item and
- * create the required chamber by intersecting all activity domains
- * that contain the facet and have a full-dimensional intersection with
- * the other side of the facet.  For each of the interior facets, we
- * again create todo items, taking care to cancel opposite todo items.

-# SYNOPSIS
-#
-#   AX_CC_MAXOPT
-#
-# DESCRIPTION
-#
-#   Try to turn on "good" C optimization flags for various compilers and
-#   architectures, for some definition of "good". (In our case, good for
-#   FFTW and hopefully for other scientific codes. Modify as needed.)
-#
-#   The user can override the flags by setting the CFLAGS environment
-#   variable. The user can also specify --enable-portable-binary in order to
-#   disable any optimization flags that might result in a binary that only
-#   runs on the host architecture.
-#
-#   Note also that the flags assume that ANSI C aliasing rules are followed
-#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
-#   computations can be re-ordered as needed.
-#
-#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
-#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

-# SYNOPSIS
-#
-#   AX_CREATE_PKGCONFIG_INFO [(outputfile, [requires [,libs [,summary [,cflags [, ldflags]]]]])]
-#
-# DESCRIPTION
-#
-#   Defaults:
-#
-#     $1 = $PACKAGE_NAME.pc
-#     $2 = (empty)
-#     $3 = $PACKAGE_LIBS $LIBS (as set at that point in configure.ac)
-#     $4 = $PACKAGE_SUMMARY (or $1 Library)
-#     $5 = $CPPFLAGS $PACKAGE_CFLAGS (as set at the point in configure.ac)
-#     $6 = $LDFLAGS $PACKAGE_LDFLAGS (as set at the point in configure.ac)
-#
-#     PACKAGE_NAME defaults to $PACKAGE if not set.
-#     PACKAGE_LIBS defaults to -l$PACKAGE_NAME if not set.
-#
-#   The resulting file is called $PACKAGE.pc.in / $PACKAGE.pc
-#
-#   You will find this macro most useful in conjunction with
-#   ax_spec_defaults that can read good initializers from the .spec file. In
-#   consequencd, most of the generatable installable stuff can be made from
-#   information being updated in a single place for the whole project.

-# SYNOPSIS
-#
-#   AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
-#
-# DESCRIPTION
-#
-#   the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
-#   existence of an include file <stdint.h> that defines a set of typedefs,
-#   especially uint8_t,int32_t,uintptr_t. Many older installations will not
-#   provide this file, but some will have the very same definitions in
-#   <inttypes.h>. In other enviroments we can use the inet-types in
-#   <sys/types.h> which would define the typedefs int8_t and u_int8_t
-#   respectivly.
-#
-#   This macros will create a local "_stdint.h" or the headerfile given as
-#   an argument. In many cases that file will just "#include <stdint.h>" or
-#   "#include <inttypes.h>", while in other environments it will provide the
-#   set of basic 'stdint's definitions/typedefs:
-#
-#     int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
-#     int_least32_t.. int_fast32_t.. intmax_t
-#
-#   which may or may not rely on the definitions of other files, or using
-#   the AC_CHECK_SIZEOF macro to determine the actual sizeof each type.
-#
-#   if your header files require the stdint-types you will want to create an
-#   installable file mylib-int.h that all your other installable header may
-#   include. So if you have a library package named "mylib", just use
-#
-#        AX_CREATE_STDINT_H(mylib-int.h)
-#
-#   in configure.ac and go to install that very header file in Makefile.am
-#   along with the other headers (mylib.h) - and the mylib-specific headers
-#   can simply use "#include <mylib-int.h>" to obtain the stdint-types.
-#
-#   Remember, if the system already had a valid <stdint.h>, the generated
-#   file will include it directly. No need for fuzzy HAVE_STDINT_H things...
-#   (oops, GCC 4.2.x has deliberatly disabled its stdint.h for non-c99
-#   compilation and the c99-mode is not the default. Therefore this macro
-#   will not use the compiler's stdint.h - please complain to the GCC
-#   developers).

-# SYNOPSIS
-#
-#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
-#
-# DESCRIPTION
-#
-#   This macro tries to guess the "native" arch corresponding to the target
-#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
-#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
-#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
-#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
-#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
-#
-#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
-#   the flag is set to -mtune (or equivalent) so that the architecture is
-#   only used for tuning, but the instruction set used is still portable. In
-#   the latter case, the flag is set to -march (or equivalent) so that
-#   architecture-specific instructions are enabled.
-#
-#   The user can specify --with-gcc-arch=<arch> in order to override the
-#   macro's choice of architecture, or --without-gcc-arch to disable this.
-#
-#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
-#   called unless the user specified --with-gcc-arch manually.
-#
-#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
-#
-#   (The main emphasis here is on recent CPUs, on the principle that doing
-#   high-performance computing on old hardware is uncommon.)

-# SYNOPSIS
-#
-#   AX_GCC_X86_CPUID(OP)
-#
-# DESCRIPTION
-#
-#   On Pentium and later x86 processors, with gcc or a compiler that has a
-#   compatible syntax for inline assembly instructions, run a small program
-#   that executes the cpuid instruction with input OP. This can be used to
-#   detect the CPU type.
-#
-#   On output, the values of the eax, ebx, ecx, and edx registers are stored
-#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
-#   ax_cv_gcc_x86_cpuid_OP.
-#
-#   If the cpuid instruction fails (because you are running a
-#   cross-compiler, or because you are not using gcc, or because you are on
-#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
-#   is set to the string "unknown".
-#
-#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.

-# SYNOPSIS
-#
-#   AX_CC_MAXOPT
-#
-# DESCRIPTION
-#
-#   Try to turn on "good" C optimization flags for various compilers and
-#   architectures, for some definition of "good". (In our case, good for
-#   FFTW and hopefully for other scientific codes. Modify as needed.)
-#
-#   The user can override the flags by setting the CFLAGS environment
-#   variable. The user can also specify --enable-portable-binary in order to
-#   disable any optimization flags that might result in a binary that only
-#   runs on the host architecture.
-#
-#   Note also that the flags assume that ANSI C aliasing rules are followed
-#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
-#   computations can be re-ordered as needed.
-#
-#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
-#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

-# SYNOPSIS
-#
-#   AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
-#
-# DESCRIPTION
-#
-#   Try to find a compiler option that enables most reasonable warnings.
-#
-#   For the GNU CC compiler it will be -Wall (and -ansi -pedantic) The
-#   result is added to the shellvar being CFLAGS by default.
-#
-#   Currently this macro knows about GCC, Solaris C compiler, Digital Unix C
-#   compiler, C for AIX Compiler, HP-UX C compiler, IRIX C compiler, NEC
-#   SX-5 (Super-UX 10) C compiler, and Cray J90 (Unicos 10.0.0.8) C
-#   compiler.
-#
-#    - $1 shell-variable-to-add-to : CFLAGS
-#    - $2 add-value-if-not-found : nothing
-#    - $3 action-if-found : add value to shellvariable
-#    - $4 action-if-not-found : nothing

-dnl  implementation tactics:
-dnl   the for-argument contains a list of options. The first part of
-dnl   these does only exist to detect the compiler - usually it is
-dnl   a global option to enable -ansi or -extrawarnings. All other
-dnl   compilers will fail about it. That was needed since a lot of
-dnl   compilers will give false positives for some option-syntax
-dnl   like -Woption or -Xoption as they think of it is a pass-through
-dnl   to later compile stages or something. The "%" is used as a
-dnl   delimimiter. A non-option comment can be given after "%%" marks

-# SYNOPSIS
-#
-#   AX_CREATE_PKGCONFIG_INFO [(outputfile, [requires [,libs [,summary [,cflags [, ldflags]]]]])]
-#
-# DESCRIPTION
-#
-#   Defaults:
-#
-#     $1 = $PACKAGE_NAME.pc
-#     $2 = (empty)
-#     $3 = $PACKAGE_LIBS $LIBS (as set at that point in configure.ac)
-#     $4 = $PACKAGE_SUMMARY (or $1 Library)
-#     $5 = $CPPFLAGS $PACKAGE_CFLAGS (as set at the point in configure.ac)
-#     $6 = $LDFLAGS $PACKAGE_LDFLAGS (as set at the point in configure.ac)
-#
-#     PACKAGE_NAME defaults to $PACKAGE if not set.
-#     PACKAGE_LIBS defaults to -l$PACKAGE_NAME if not set.
-#
-#   The resulting file is called $PACKAGE.pc.in / $PACKAGE.pc
-#
-#   You will find this macro most useful in conjunction with
-#   ax_spec_defaults that can read good initializers from the .spec file. In
-#   consequencd, most of the generatable installable stuff can be made from
-#   information being updated in a single place for the whole project.

-# SYNOPSIS
-#
-#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
-#
-# DESCRIPTION
-#
-#   This macro tries to guess the "native" arch corresponding to the target
-#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
-#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
-#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
-#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
-#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
-#
-#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
-#   the flag is set to -mtune (or equivalent) so that the architecture is
-#   only used for tuning, but the instruction set used is still portable. In
-#   the latter case, the flag is set to -march (or equivalent) so that
-#   architecture-specific instructions are enabled.
-#
-#   The user can specify --with-gcc-arch=<arch> in order to override the
-#   macro's choice of architecture, or --without-gcc-arch to disable this.
-#
-#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
-#   called unless the user specified --with-gcc-arch manually.
-#
-#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
-#
-#   (The main emphasis here is on recent CPUs, on the principle that doing
-#   high-performance computing on old hardware is uncommon.)

-# SYNOPSIS
-#
-#   AX_GCC_X86_CPUID(OP)
-#
-# DESCRIPTION
-#
-#   On Pentium and later x86 processors, with gcc or a compiler that has a
-#   compatible syntax for inline assembly instructions, run a small program
-#   that executes the cpuid instruction with input OP. This can be used to
-#   detect the CPU type.
-#
-#   On output, the values of the eax, ebx, ecx, and edx registers are stored
-#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
-#   ax_cv_gcc_x86_cpuid_OP.
-#
-#   If the cpuid instruction fails (because you are running a
-#   cross-compiler, or because you are not using gcc, or because you are on
-#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
-#   is set to the string "unknown".
-#
-#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-/**
- * insert_guard function:
- * This function inserts a guard in the clast.
- * A guard on an element (level) is :
- * -> the conjunction of all the existing constraints where the coefficient of
- *    this element is 0 if the element is an iterator,
- * -> the conjunction of all the existing constraints if the element isn't an
- *    iterator.
- * For instance, considering these constraints and the element j:
- * -3*i +2*j -M >= 0
- *  2*i      +M >= 0
- * this function should return 'if (2*i+M>=0) {'.
- * - matrix is the polyhedron containing all the constraints,
- * - level is the column number of the element in matrix we want to use,
- * - the infos structure gives the user some options about code printing,
- *   the number of parameters in matrix (nb_par), and the arrays of iterator
- *   names and parameters (iters and params). 
- **
- * - November  3rd 2001: first version. 
- * - November 14th 2001: a lot of 'purifications'. 
- * - July     31th 2002: (debug) some guard parts are no more redundants. 
- * - August   12th 2002: polyhedra union ('or' conditions) are now supported.
- * - October  27th 2005: polyhedra union ('or' conditions) are no more supported
- *                       (the need came from loop_simplify that may result in
- *                       domain unions, now it should be fixed directly in
- *                       cloog_loop_simplify).

- * insert_loop function:

- * The iterator (level) of
- * the current loop is given by 'level': this is the column number of the
- * domain corresponding to the current loop iterator. The data of a loop are
- * written in this order:
- * 1. The guard of the loop, i.e. each constraint in the domain that does not
- *    depend on the iterator (when the entry in the column 'level' is 0).
- * 2. The iteration domain of the iterator, given by the constraints in the
- *    domain depending on the iterator, i.e.:
- *    * an equality if the iterator has only one value (possibly preceded by
- *      a guard verifying if this value is integral), *OR*
- *    * a loop from the minimum possible value of the iterator to the maximum
- *      possible value.
- * 3. The included statement block.
- * 4. The inner loops (recursive call).
- * 5. The following loops (recursive call).
- * - level is the recursion level or the iteration level that we are printing,
- * - the infos structure gives the user some options about code printing,
- *   the number of parameters in domain (nb_par), and the arrays of iterator
- *   names and parameters (iters and params).

- * - April     19th 2003: (debug) NULL loop support. 
- * - June      29th 2003: non-unit strides support.
- * - April     28th 2005: (debug) level is level+equality when print statement!
- * - June      16th 2005: (debug) the N. Vasilache normalization step has been
- *                        added to avoid iteration duplication (see DaeGon Kim

- * it is equal or opposite to a single variable or parameter.

- * For instance:

-CLooG is a software which generates loops for scanning Z-polyhedra. That is,
-CLooG finds the code or pseudo-code where each integral point of one or more
-parametrized polyhedron or parametrized polyhedra union is reached. CLooG is
-designed to avoid control overhead and to produce a very efficient code.
-
-Its input is some data on the polyhedra to scan, basically the system of
-affine inequalities that define them, and a context that defines some
-properties known on the parameters if any. The output is the pseudo scanning
-code. Many facilities are provided to generate a near-to-be-compileable code,
-and every useful functions to generate the code may be called from the CLooG
-library.

-
-If you obtained CLooG from the git repository, then you first
-need to obtain the submodules and create a configure script.
-
-  ./get_submodules.sh
-  ./autogen.sh
-
-The first step is only needed if you plan on using the isl backend.
-
-The configure shell script attempts to guess correct values for various
-system-dependent variables used during compilation. It uses those values to
-create a Makefile. The file configure.ac is used to create configure by a
-program called autoconf.  You only need configure.ac if you want to change
-it or regenerate configure using a newer version of autoconf.
-
-The simplest way to compile this package is:
-cd to the directory containing the package's source code and type 
-
-  ./configure
-
-to configure the package for your system (while running, configure prints
-some messages telling which features it is checking for). To compile the
-package, type
-
-  make
-  
-
-to install the program and/or the library, type
-
-  make install
-
-you can remove the program binaries and object files from the source code
-directory by typing
-  
-  make clean
-  
-To also remove the files that configure created (so you can compile the
-package for a different kind of computer) type
-  
-  make distclean
-
-#   **-------------------------------------------------------------------**
-#   **                           III. Options                            **
-#   **-------------------------------------------------------------------**/
-
-By default,  make will install the package's files in /usr/local/bin,
-/usr/local/lib, etc. You can specify an installation prefix other than 
-/usr/local by giving onfigure the option --prefix=PATH.
-
-By default, configure will use the isl that comes bundled with CLooG.
-Using the --with-isl option of configure the user can specify that "no" isl,
-a previously installed ("system") isl or a "build" isl should be used.
-In the latter case, the user should also specify the build location
-using --with-isl-builddir=PATH.  In case of an installed isl,
-the installation location can be specified using the
---with-isl-prefix=PATH and --with-isl-exec-prefix=PATH options of configure.
-
-By default, configure will seek the PolyLib in standard locations.
-If necessary, you can specify the PolyLib's path by giving configure the
-option --with-polylib-prefix=PATH and/or --with-polylib-exec-prefix=PATH.
-
-By default, configure will seek the GMP library in standard locations.
-If necessary, you can specify the GMP's path by giving configure the
-option --with-gmp-prefix=PATH and/or --with-gmp-exec-prefix=PATH.
-
-By default, when using the PolyLib backend,
-CLooG and its library are built using 64 bits integer
-representation. You can choose to specify explicitly others integer
-representations by using:
---with-bits=32  for 32 bits integers,
---with-bits=64  for 64 bits integers (default),
---with-bits=gmp for multiple precision integers.

-#   **-------------------------------------------------------------------**/
-
-To run CLooG, simply type 'cloog', optionally followed by the name of an
-input file. You can type 'cloog -h' or 'cloog --help' for some help.
-For more informations, please check the ./doc subdirectory.

-#   **-------------------------------------------------------------------**/
-
-1. What does CLooG means ?
-
-CLooG is the Chunky LOOp Generator, Chunky is an automatic loop optimizer for
-data locality. CLooG is a completely independent part of the Chunky project.
-Pronounce 'CLooG' as 'klug', which means 'sly' in german :-).
-
-2. CLooG do not compile, what should I do ?
-
-CLooG should compile everywhere (assuming that PolyLib is still there), thus
-there is a problem or the documentation is not clear, in both case it is
-necessary to ask the author(s) !
-
-3. I need a feature that CLooG do not implement, what should I do ?
-
-There are two ways. First, CLooG is a LGPL software and library. So you
-are welcome to improve it yourself ;-) ! Many project have been successful, it
-is -maybe- a sign that this is not too hard to put your hands inside the
-source. Second, just ask the author(s) :-) ! Maybe a lot of people would be
-interessed by such feature, maybe many people asked for it before, maybe it's
-trivial to implement (and even)... Please just never hesitate to ask the
-author(s) !
-
-4. I implemented a cool feature, can I submit it ?

-Obviously you are welcome to send the author(s) any improvement. But obviously
-we are quite careful with readability, correctness and stability, and the
-author(s) will read, check and check again any contribution before including it.
-Thus, it can take time... There are few basic rules to write contributions:
-- (1) Do never change the indentation of any part of the code that is not yours.
-- (2) Do never send codes that use more than 80 columns.
-- (3) Do never send codes without a lot of comments in (bad or good) english.
-- (4) Do never send codes with obscure and/or non-english variable names.
-- (5) Use C89, just C, only C (note: "//" comments are not C89,
-  variable declaration elsewhere than at the beginning of a block, is not C89).
-- (6) Read doc/SubmittingPatches
-Please understand that in order to live for a long time, and to be used in many
-projects the very first priority for CLooG is to be readable and documented.
-
-5. Is CLooG bug free ?
-
-No, who can ? ClooG is a complex program, and we do not pretend it to be bug
-free. Nevertheless because it has been tested and tested, we are fairly sure
-that CLooG results with default options have good chances to be satisfactory.
-If you find a result that looks strange, inadequate or incorrect, please send:
-- (1) The input file to the author(s).
-- (2) The output.
-- (3) The first line given by typing 'cloog -v'.
-- (4) All your command line options to achieve the result.
-We will try to explain the result or to fix the problem as soon as possible.
-
-6. How can I contact the author(s) ?
-
-Just send a mail to cloog-development@googlegroups.com

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files

-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-@chapter Introduction
-CLooG is a free software and library generating loops for scanning Z-polyhedra.
-That is, it finds a code (e.g. in C, FORTRAN...) that reaches each integral
-point of one or more parameterized polyhedra. CLooG has been originally
-written to solve the code generation problem for optimizing compilers based on
-the polytope model. Nevertheless it is used now in various area, e.g., to build
-control automata for high-level synthesis or to find the best polynomial
-approximation of a function. CLooG may help in any situation where scanning
-polyhedra matters. It uses the best state-of-the-art code generation
-algorithm known as the Quiller@'e et al. algorithm (@pxref{Qui00})
-with our own improvements and extensions (@pxref{Bas04}).
-The user has full control on generated code quality.
-On one hand, generated code size has to be tuned for sake of
-readability or instruction cache use. On the other hand, we must ensure that
-a bad control management does not hamper performance of the generated code,
-for instance by producing redundant guards or complex loop bounds.
-CLooG is specially designed to avoid control overhead and to produce a very
-efficient code.
-
-CLooG stands for @emph{Chunky Loop Generator}: it is a part of the Chunky
-project, a research tool for data locality improvement (@pxref{Bas03a}).
-It is designed
-also to be the back-end of automatic parallelizers like LooPo (@pxref{Gri04}).
-Thus it is very
-compilable code oriented and provides powerful program transformation
-facilities. Mainly, it allows the user to specify very general schedules where, 
-e.g., unimodularity or invertibility of the transformation doesn't matter.
-
-The current version is still under
-evaluation, and there is no guarantee that the upward compatibility
-will be respected (but the previous API has been stable for two years,
-we hope this one will be as successful -and we believe it-).
-A lot of reports are necessary to freeze the library
-API and the input file shape. Most API changes from 0.12.x to 0.14.x
-have been requested by the users themselves.
-Thus you are very welcome and encouraged
-to post reports on bugs, wishes, critics, comments, suggestions or
-successful experiences in the forum of @code{http://www.CLooG.org}
-or to send them to cedric.bastoul@@inria.fr directly.

-@node Basics
-@section Basically, what's the point ?
-If you want to use CLooG, this is because you want to scan or to find
-something inside the integral points of a set of polyhedra. There are many
-reasons for that. Maybe you need the generated code itself because it
-actually implements a very smart program transformation you found.
-Maybe you want to use the generated code
-because you know that the solution of your problem belongs to the integral
-points of those damned polyhedra and you don't know which one. Maybe you just
-want to know if a polyhedron has integral points depending on some parameters,
-which is the lexicographic minimum, maximum, the third on the basis of the
-left etc. Probably you have your own reasons to use CLooG.
-
-Let us illustrate a basic use of CLooG. Suppose we have a set of affine
-constraints that describes a part of a whatever-dimensional space,
-called a @strong{domain}, and we
-want to scan it. Let us consider for instance the following set of constraints
-where @samp{i}
-and @samp{j} are the unknown (the two dimensions of the space) and
-@samp{m} and @samp{n} are the parameters (some symbolic constants):
-@example
-@group
-2<=i<=n
-2<=j<=m
-j<=n+2-i
-@end group
-@end example
-Let us also consider that we have a partial knowledge of the parameter values,
-called the @strong{context}, expressed as affine constraints as well,
-for instance:
-@example
-@group
-m>=2
-n>=2
-@end group
-@end example
-Note that using parameters is optional, if you are not comfortable with
-parameter manipulation, just replace them with any scalar value that fits
-@code{m>=2} and @code{n>=2}.
-A graphical representation of this part of the 2-dimensional space, where
-the integral points are represented using heavy dots would be for instance:
-
-@image{images/basic,6cm}
-
-The affine constraints of both the domain and the context are what we will
-provide to CLooG as input (in a particular shape that will be described later).
-The output of CLooG is a pseudo-code to scan the integral points of the
-input domain according to the context:
-@example
-@group
-for (i=2;i<=n;i++) @{
-  for (j=2;j<=min(m,-i+n+2);j++) @{    
-    S1(i,j) ;
-  @}
-@}
-@end group
-@end example
-If you felt such a basic example is yet interesting, there is a good chance
-that CLooG is appropriate for you. CLooG can do much more: scanning several
-polyhedra or unions of polyhedra at the same time, applying general affine
-transformations to the polyhedra, generate compilable code etc. Welcome
-to the CLooG's user's guide !
-
-@node Scattering
-@section Defining a Scanning Order: Scattering Functions
-In CLooG, domains only define the set of integral points to scan and their
-coordinates. In particular, CLooG is free to choose the scanning order for
-generating the most efficient code. This means, for optimizing/parallelizing
-compiler people, that CLooG doesn't make any speculation on dependences on and
-between statements (by the way, it's not its job !).
-For instance, if an user give to
-CLooG only two domains @code{S1:1<=i<=n}, @code{S2:1<=i<=n} and the context
-@code{n>=1}, the following pseudo-codes are considered to be equivalent:
-
-@example
-@group
-/* A convenient target pseudo-code. */
-for (i=1;i<=N;i++) @{
- S1(i) ;
-@}
-for (i=1;i<=N;i++) @{
- S2(i) ;
-@}
-@end group
-@end example
-
-@example
-@group
-/* Another convenient target pseudo-code. */
-for (i=1;i<=N;i++) @{
- S1(i) ;
- S2(i) ;
-@}
-@end group
-@end example
-
-The default behaviour
-of CLooG is to generate the second one, since it is optimized in control. 
-It is right if there are no data dependences
-between @code{S1} and @code{S2}, but wrong otherwise. 
-
-Thus it is often useful to force scanning to respect a given order. This can be
-done in CLooG by using @strong{scattering functions}. Scattering is a
-shortcut for scheduling, allocation, chunking functions and the like we can
-find in the restructuring compilation literature. There are a lot of reasons
-to scatter the integral points of the domains (i.e. the statement instances
-of a program, for compilation people), parallelization or optimization are good
-examples. For instance, if the user wants for any reason to set some
-precedence constraints between the statements of our example above
-in order to force the generation of the
-first code, he can do it easily by setting (for example) the following
-scheduling functions:
-
-@tex
-$$\theta _{S1}(i) =  (1)$$
-$$\theta _{S2}(j) =  (2)$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i) = (1)
-T_S2(j) = (2)
-@end group
-@end example
-@end ifnottex
-
-This scattering means that each integral point of the domain @code{S1}
-is scanned at logical date @code{1} while each integral point of the domain
-@code{S2} is scanned at logical date @code{2}. As a result, the whole
-domain @code{S1} is scanned before domain @code{S2} and the first code in our
-example is generated.
-
-The user can set every kind of affine scanning order thanks to the
-scattering functions. Each domain has its own scattering function and
-each scattering function may be multi-dimensional. A multi-dimensional logical
-date may be seen as classical date (year,month,day,hour,minute,etc.) where
-the first dimensions are the most significant. Each scattering dimension
-may depend linearly on the original dimensions (e.g., @code{i}), the
-parameters (e.g., @code{n}) ans scalars (e.g., @code{2}).
-
-A very useful example of multi-dimensional scattering functions is, for
-compilation people, the scheduling of the original program.
-The basic data to use for code generation are statement iteration domains.
-As we saw, these data are not sufficient to rebuild the original
-program (what is the ordering between instances of different statements ?).
-The missing data can be put in the scattering functions as the original
-scheduling. The method to compute it is quite simple (@pxref{Fea92}). The idea is to
-build an abstract syntax tree of the program and to read the scheduling for
-each statement. For instance, let us consider the following implementation of
-a Cholesky factorization:
-
-@example
-@group
-/* A Cholesky factorization kernel. */
-for (i=1;i<=N;i++) @{
-  for (j=1;j<=i-1;j++) @{
-    a[i][i] -= a[i][j] ;           /* S1 */
-  @}
-  a[i][i] = sqrt(a[i][i]) ;        /* S2 */
-  for (j=i+1;j<=N;j++) @{
-    for (k=1;k<=i-1;k++) @{
-      a[j][i] -= a[j][k]*a[i][k] ; /* S3 */
-    @}
-    a[j][i] /= a[i][i] ;           /* S4 */
-    @}
-  @}
-@}
-@end group
-@end example
-
-The corresponding abstract syntax tree is given in the following figure.
-It directly gives the scattering functions (schedules) for all the
-statements of the program.
-
-@image{images/tree,6cm}
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i,j)^T    &$=  (0,i,0,j,0)^T$\cr
-                \theta _{S2}(i)        &$=  (0,i,1)^T$\cr
-                \theta _{S3}(i,j,k)^T  &$=  (0,i,2,j,0,k,0)^T$\cr
-                \theta _{S4}(i,j)^T    &$=  (0,i,2,j,1)^T$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i,j)^T   = (0,i,0,j,0)^T
-T_S2(i)       = (0,i,1)^T
-T_S3(i,j,k)^T = (0,i,2,j,0,k,0)^T
-T_S4(i,j)^T   = (0,i,2,j,1)^T
-@end group
-@end example
-@end ifnottex
-
-These schedules depend on the iterators and give for each instance of each
-statement a unique execution date. Using such scattering functions allow
-CLooG to re-generate the input code.

-of CLooG is not very complex and we present in this section how to generate the
-code corresponding to a basic example discussed earlier (@pxref{Basics}).
-
-The problem is to find the code that scans a 2-dimensional polyhedron
-where @samp{i} and @samp{j} are the unknown (the two dimensions of the space)
-and @samp{m} and @samp{n} are the parameters (the symbolic constants),
-defined by the following set of constraints:
-@example
-@group
-2<=i<=n
-2<=j<=m
-j<=n+2-i
-@end group
-@end example
-@noindent We also consider a partial knowledge of the parameter values,
-expressed thanks to the following affine constraints:
-@example
-@group
-m>=2
-n>=2
-@end group
-@end example
-
-An input file that corresponds to this problem, and asks for a generated
-code in C, may be the following. Note that we do not describe here precisely
-the structure and the components of this file (@pxref{Writing The Input File}
- for such information, if you feel it necessary):
-

-@node Writing The Input File
-@section Writing The Input File
-The input text file contains a problem description, i.e. the context,
-the domains and the scattering functions.
-Because CLooG is very 'compilable code generation oriented', we can associate
-some additional informations to each domain. We call this association a
-@emph{statement}. The set of all informations is 
-called a @emph{program}. The input file respects the grammar below
-(terminals are preceded by "_"):
-
-@example
-File             ::= Program
-Program          ::= Context Statements Scattering
-Context          ::= Language      Domain_union   Naming
-Statements       ::= Nb_statements Statement_list Naming
-Scatterings      ::= Nb_functions  Scattering_list Naming
-Naming           ::= Option Name_list
-Name_list        ::= _String   Name_list      | (void)
-Statement_list   ::= Statement Statement_list | (void)
-Domain_list      ::= _Domain   Domain_list    | (void)
-Scattering_list  ::= Domain_union Scattering_list | (void)
-Statement        ::= Iteration_domain 0 0 0
-Iteration_domain ::= Domain_union
-Domain_union     ::= Nb_domains Domain_list
-Option           ::= 0 | 1
-Language         ::= c | f
-Nb_statements    ::= _Integer
-Nb_domains       ::= _Integer
-Nb_functions     ::= _Integer
-@end example
-
-Note: if there is only one domain in a @samp{Domain_union},
-i.e., if @samp{Nb_domains} is 1, then this 1 may be omitted.
-
-@itemize @bullet
-@item  @samp{Context} represents the informations that are
-       shared by all the statements. It consists on
-       the language used (which can be @samp{c} for C or @samp{f} for FORTRAN 90)
-       and the global constraints on parameters.
-       These constraints are essential
-       since they give to CLooG the number of parameters. If there is no
-       parameter or no constraints on parameters, just give a constraint
-       always satisfied like @math{1 \geq 0}. @samp{Naming} sets the parameter
-       names.
-       If the naming option @samp{Option} is 1, parameter names will be read
-       on the next line. There must be exactly as many names as parameters.
-       If the naming option @samp{Option} is 0, parameter names are
-       automatically generated. The name of the first parameter will
-       be @samp{M}, and the name of the @math{(n+1)^{th}} parameter directly
-       follows the name of the @math{n^{th}} parameter in ASCII code.
-       It is the user responsibility to ensure that parameter names,
-       iterators and scattering dimension names are different. 
-@item  @samp{Statements} represents the informations on the statements.
-       @samp{Nb_statements} is the number of statements in the program, 
-       i.e. the number of @samp{Statement} items in the @samp{Statement_list}.
-       @samp{Statement} represents the informations on a given statement.
-       To each statement is associated a domain
-       (the statement iteration domain: @samp{Iteration_domain}) and three
-       zeroes that represents future options.
-       @samp{Naming} sets the iterator names. If the naming option
-       @samp{Option} is 1, the iterator names
-       will be read on the next line. There must be exactly as many names as
-       nesting level in the deepest iteration domain. If the naming option
-       @samp{Option} is 0, iterator names are automatically generated.
-       The iterator name of the outermost loop will be @samp{i}, and the
-       iterator name of the loop at level @math{n+1} directly follows the 
-       iterator name of the loop at level @math{n} in ASCII code. 
-@item  @samp{Scatterings} represents the informations on scattering functions.
-       @samp{Nb_functions} is the number of functions (it must be
-       equal to the number of statements or 0 if there is no scattering
-       function). The functions themselves are represented through
-       @samp{Scattering_list}.
-       @samp{Naming} sets the scattering dimension names. If the naming option
-       @samp{Option} is 1, the scattering dimension names will be read on the
-       next line.
-       There must be exactly as many names as scattering dimensions. If the
-       naming option @samp{Option} is 0, scattering dimension names are automatically
-       generated. The name of the @math{n^{th}} scattering dimension
-       will be @samp{cn}.

-@node Domain Representation
-@subsection Domain Representation
-As shown by the grammar, the input file describes the various informations
-thanks to characters, integers and domains. Each domain is defined by a set of
-constraints in the PolyLib format (@pxref{Wil93}). They have the
-following syntax:
-@enumerate
-@item some optional comment lines beginning with @samp{#},
-@item the row and column numbers, possibly followed by comments,
-@item the constraint rows, each row corresponds to a constraint the
-      domain have to satisfy. Each row must be on a single line and is possibly
-      followed by comments. The constraint is an equality @math{p(x) = 0} if the
-      first element is 0, an inequality  @math{p(x) \geq 0} if the first element
-      is 1. The next elements are the unknown coefficients, followed by
-      the parameter coefficients. The last element is the constant factor.
-@end enumerate
-For instance, assuming that @samp{i}, @samp{j} and @samp{k} are iterators and
-@samp{m} and @samp{n} are parameters, the domain defined by the following
-constraints :
-
-@tex
-$$
-\hbox{$ \cases{ -i     + m &$\geq 0$\cr
-                    -j + n &$\geq 0$\cr
-                 i + j - k &$\geq 0$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-   -i + m >= 0
-   -j + n >= 0
-i + j - k >= 0
-@end group
-@end example
-@end ifnottex
-
-@noindent can be written in the input file as follows :
-
-@example
-@group
-# This is the domain
-3 7                      # 3 lines and 7 columns
-# eq/in i  j  k  m  n  1 
-    1  -1  0  0  1  0  0 #    -i + m >= 0
-    1   0 -1  0  0  1  0 #    -j + n >= 0
-    1   1  1 -1  0  0  0 # i + j - k >= 0
-@end group
-@end example
-
-Each iteration domain @samp{Iteration_domain} of a given statement
-is a union of polyhedra
-@samp{Domain_union}. A union is defined by its number of elements
-@samp{Nb_domains} and the elements themselves @samp{Domain_list}.
-For instance, let us consider the following pseudo-code:
-
-@example
-@group
-for (i=1;i<=n;i++) @{
-  if ((i >= m) || (i <= 2*m))
-    S1 ;
-  for (j=i+1;j<=m;j++)
-    S2 ;
-@} 
-@end group
-@end example
-
-@noindent The iteration domain of @samp{S1} can be divided into two
-polyhedra and written in the input file as follows:
-
-@example
-@group
-2 # Number of polyhedra in the union
-# First domain
-3 5                # 3 lines and 5 columns
-# eq/in i  m  n  1 
-    1   1  0  0 -1 #  i >= 1
-    1  -1  0  1  0 #  i <= n
-    1   1 -1  0  0 #  i >= m
-# Second domain
-3 5                # 3 lines and 5 columns
-# eq/in i  m  n  1 
-    1   1  0  0 -1 #  i >= 1
-    1  -1  0  1  0 #  i <= n
-    1  -1  2  0  0 #  i <= 2*m
-@end group
-@end example
-
-@node Scattering Representation
-@subsection Scattering Function Representation
-Scattering functions are depicted in the input file thanks a representation
-very close to the domain one.
-An integer gives the number of functions @samp{Nb_functions} and each function
-is represented by a domain. Each line of the domain corresponds to an equality
-defining a dimension of the function. Note that at present
-(CLooG @value{VERSION})
-@strong{all functions must have the same scattering dimension number}. If a
-user wants to set scattering functions with different dimensionality, he has
-to complete the smaller one with zeroes to reach the maximum dimensionality.
-For instance, let us consider the following code and
-scheduling functions:
-
-@example
-@group
-for (i=1;i<=n;i++) @{
-  if ((i >= m) || (i <= 2*m))
-    S1 ;
-  for (j=i+1;j<=m;j++)
-    S2 ;
-@} 
-@end group
-@end example
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i)      &$=  (i,0)^T$\cr
-                \theta _{S2}(i,j)^T  &$=  (n,i+j)^T$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i)     = (i,0)^T
-T_S2(i,j)^T = (n,i+j)^T
-@end group
-@end example
-@end ifnottex
-
-
-@noindent This scheduling can be written in the input file as follows:
-
-@example
-@group
-2 # Number of scattering functions
-# First function
-2 7                          # 2 lines and 7 columns
-# eq/in c1 c2  i  m  n  1 
-    0    1  0 -1  0  0  0    #  c1 = i
-    0    0  1  0  0  0  0    #  c2 = 0
-# Second function
-2 8                          # 2 lines and 8 columns
-# eq/in c1 c2  i  j  m  n  1 
-    0    1  0  0  0  0 -1  0 #  c1 = n
-    0    0  1 -1 -1  0  0  0 #  c2 = i+j
-@end group
-@end example
-The complete input file for the user who wants to generate the code for this
-example with the preceding scheduling would be
-(this file is provided in the CLooG distribution
-as @code{test/manual_scattering.cloog}:

-@subsection Last Depth to Optimize Control @code{-l <depth>}
-
-@code{-l <depth>}: this option sets the last loop depth to be optimized in
-control. The higher this depth, the less control overhead.
-For instance, with some input file, a user can generate
-different pseudo-codes with different @code{depth} values as shown below.
-@example
-@group
-/* Generated using a given input file and @strong{option -l 1} */
-for (i=0;i<=M;i++) @{
-  S1 ;
-  for (j=0;j<=N;j++) @{
-    S2 ;
-  @}
-  for (j=0;j<=N;j++) @{
-    S3 ;
-  @}
-  S4 ;
-@}
-@end group
-@end example
-@example
-@group
-/* Generated using the same input file but @strong{option -l 2} */
-for (i=0;i<=M;i++) @{
-  S1 ;
-  for (j=0;j<=N;j++) @{
-    S2 ;
-    S3 ;
-  @}
-  S4 ;
-@}
-@end group
-@end example
-     In this example we can see that this option can change the operation
-     execution order between statements. Let us remind that CLooG does not
-     make any speculation on dependences between statements
-     (@pxref{Scattering}). Thus if nothing (i.e. scattering functions)
-     forbids this, CLooG considers the above codes to be equivalent.
-     If there is no scattering functions, the minimum value for @code{depth}
-     is 1 (in the case of 0, the user doesn't really need a loop generator !),
-     and the number of scattering dimensions otherwise (CLooG will warn the
-     user if he doesn't respect such constraint).
-     The maximum value for depth is -1 (infinity).
-     Default value is infinity.
-
-@node First Depth to Optimize Control
-@subsection First Depth to Optimize Control @code{-f <depth>}
-
-     @code{-f <depth>}: this option sets the first loop depth to be optimized
-     in control. The lower this depth, the less control overhead (and the longer
-     the generated code). For instance, with some input file, a user
-     can generate different pseudo-codes with different @code{depth} values
-     as shown below.
-     The minimum value for @code{depth} is 1, and the
-     maximum value is -1 (infinity).
-     Default value is 1.
-@example
-@group
-/* Generated using a given input file and @strong{option -f 3} */
-for (i=1;i<=N;i++) @{
-  for (j=1;j<=M;j++) @{

-@}
-@end group
-@end example
-
-@node Simple Convex Hull
-@subsection  Simple Convex Hull @code{-sh <boolean>}
-
-     @code{-sh <boolean>}: this option enables (@code{boolean=1})
-     or forbids (@code{boolean=0}) the use of an overapproximation
-     of the convex hull that may be easier to compute
-     (especially in the isl backend) and that may result in
-     simpler bounds.
-     This option works only for generated code without
-     code duplication (it means, you have to tune @code{-f} and
-     @code{-l} options first to generate only a loop nest with internal
-     guards). For instance, with the input file @code{test/union.cloog}, a user
-     can generate different pseudo-codes  as shown below.
-     Default value is 0.
-@example
-@group
-/* Generated using test/union.cloog and @strong{option -f -1 -l 2 -override} */

-     @code{-otl <boolean>}: this option allows (@code{boolean=1}) or
-     forbids (@code{boolean=0}) the simplification of loops running
-     once. Default value is 1.
-@example
-@group
-/* Generated using a given input file and @strong{option -otl 0} */
-for (j=i+1;j<=i+1;j++) @{
-  S1 ;
-@}
-@end group

-@node Equality Spreading 
-@subsection Equality Spreading @code{-esp <boolean>}
-
-     @code{-esp <boolean>}: this option allows (@code{boolean=1}) or
-     forbids (@code{boolean=0}) values spreading when there
-     are equalities. Default value is 1.
-@example
-@group
-/* Generated using a given input file and @strong{option -esp 0} */
-i = M+2 ;
-j = N ;
-for (k=i;k<=j+M;k++) @{
-  S1 ;

-@end group
-@end example
-
-
-@node First Level for Spreading 
-@subsection First Level for Spreading @code{-fsp <level>}
-
-     @code{-fsp <level>}: it can be useful to set a
-     first level to begin equality spreading. Particularly when using
-     scattering functions, the user may want to see the scattering dimension
-     values instead of spreading or hiding them. If user has set a
-     spreading, @code{level} is
-     the first level to start it. Default value is 1.
-@example
-@group
-/* Generated using a given input file and @strong{option -fsp 1} */
-for (j=0;j<=N+M;j++) @{
-  S1(i = N) ;
-@}
-for (j=0;j<=N+M;j++) @{
-  S1(i = M) ;
-@}
-@end group
-@end example
-@example
-@group
-/* Generated using the same input file but @strong{option -fsp 2} */
-c1 = N ;
-for (j=0;j<=c1+M;j++) @{
-  S1(i = c1) ;

-c1 = M ;
-for (j=0;j<=N+c1;j++) @{
-  S1(i = c1) ;
-@}
-@end group
-@end example
-
-
-@node Statement Block  
-@subsection Statement Block @code{-block <boolean>}
-
-     @code{-block <boolean>}: this option allows (@code{boolean=1}) to
-     create a statement block for each new iterator, even if there is only
-     an equality. This can be useful in order to parse the generated
-     pseudo-code. When @code{boolean} is set to 0 or when the generation
-     language is FORTRAN, this feature is disabled. Default value is 0.
-@example
-@group
-/* Generated using a given input file and @strong{option -block 0} */
-i = M+2 ;
-j = N ;
-S1 ;
-@end group
-@end example
-@example
-@group
-/* Generated using the same input file but @strong{option -block 1} */
-@{ i = M+2 ;
-  @{ j = N ;
-    S1 ;
-  @}
-@}
-@end group
-@end example
-
-
-@node Loop Strides 
-@subsection Loop Strides @code{-strides <boolean>}
-
-     @code{-strides <boolean>}: this options allows (@code{boolean=1}) to
-     handle non-unit strides for loop increments. This can remove a lot of
-     guards and make the generated code more efficient. Default value is 0.
-@example
-@group
-/* Generated using a given input file and @strong{option -strides 0} */
-for (i=1;i<=n;i++) @{
-  if (i%2 == 0) @{
-    S1(j = i/2) ;
-  @}
-  if (i%4 == 0) @{
-    S2(j = i/4) ;
-  @}
-@}
-@end group
-@end example
-@example
-@group
-/* Generated using the same input file but @strong{option -strides 1} */
-for (i=2;i<=n;i+=2) @{
-  S1(j = i/2) ;
-  if (i%4 == 0) @{
-    S2(j = i/4) ;
-  @}
-@}
-@end group
-@end example
-
-
-@node Unrolling
-@subsection First Depth to Unroll @code{-first-unroll <depth>}
-
-    @code{-first-unroll <depth>}: this option sets the first loop depth
-    to unroll.  Note that a loop is only unrolled when it is supported
-    by the backend.  In case of the isl backend, a loop is unrolled
-    if it has a lower bound that can only be incremented
-    a fixed (non-parametric) amount of times.
-
-
-@node Compilable Code
-@subsection Compilable Code @code{-compilable <value>}
-
-     @code{-compilable <value>}: this options allows (@code{value} is not 0)
-     to generate a compilable code where all parameters have the integral value
-     @code{value}. This option creates a macro for each statement. Since
-     CLooG do not know anything about the statement sources, it fills the
-     macros with a basic increment that computes the total number of
-     scanned integral points. The user may change easily the macros according
-     to his own needs. This option is possible only if the generated code is
-     in C. Default value is 0.
-@example
-@group
-/* Generated using a given input file and @strong{option -compilable 0} */
-for (i=0;i<=n;i++) @{
-  for (j=0;j<=n;j++) @{
-    S1 ;
-    S2 ;
-  @}
-  S3 ;
-@}
-@end group
-@end example
-@example
-/* Generated using the same input file but @strong{option -compilable 10} */
-/* DON'T FORGET TO USE -lm OPTION TO COMPILE. */

-  printf("Number of integral points: %d.\n",total) ;
-  return 0 ;
-@}
-@end example
-
-@node Callable Code
-@subsection Callable Code @code{-callable <boolean>}
-
-     @code{-callable <boolean>}: if @code{boolean=1}, then a @code{test}
-     function will be generated that has the parameters as arguments.
-     Similarly to the @code{-compilable} option,
-     a macro for each statement is generated.  The generated definitions of
-     these macros are as used during the correctness testing, but they
-     can easily be changed by the user to suit her own needs.
-     This option is only available if the target language is C.
-     The default value is 0.
-
-@example
-/* Generated from double.cloog with @strong{option -callable 0} */
-for (i=0;i<=M;i++) @{
-  S1 ;
-  for (j=0;j<=N;j++) @{

-@node Output
-@subsection Output @code{-o <output>}
-
-     @code{-o <output>}: this option sets the output file. @code{stdout} is a
-     special value: when used, output is standard output.
-     Default value is @code{stdout}.
-
-@node OpenScop
-@subsection OpenScop @code{-openscop}
-
-     @code{-openscop}: this option states that the input file complies to
-     the OpenScop specification instead of the native file format
-     (@pxref{Bas11}). This option is available only if the OpenScop
-     support has been enabled at compile time (@pxref{Optional Features}).
-

-@section A Full Example
-
-Let us consider the allocation problem of a Gaussian elimination, i.e. we want
-to distribute the various statement instances of the compute kernel onto
-different processors. The original code is the following:
-@example
-@group
-for (i=1;j<=N-1;i++) @{
-  for (j=i+1;j<=N;j++) @{
-    c[i][j] = a[j][i]/a[i][i] ;    /* S1 */
-    for (k=i+1;k<=N;k++) @{
-      a[j][k] -= c[i][j]*a[i][k] ; /* S2 */
-    @}
-  @}
-@}
-@end group
-@end example
-
-@noindent The best affine allocation functions can be found by any good automatic
-parallelizer like LooPo (@pxref{Gri04}):
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i,j)^T    &$=  (i)$\cr
-                \theta _{S2}(i,j,k)^T  &$=  (k)$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i,j)^T   = (i)
-T_S2(i,j,k)^T = (k)
-@end group
-@end example
-@end ifnottex
-
-@noindent To ensure that on each processor, the set of statement instances is
-executed according to the original ordering, we add as minor scattering
-dimensions the original scheduling (@pxref{Scattering}):
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i,j)^T    &$=  (i,0,i,0,j,0)^T$\cr
-                \theta _{S2}(i,j,k)^T  &$=  (k,0,i,0,j,1,k,0)^T$}$}
-$$
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1(i,j)^T   = (i,0,i,0,j,0)^T
-T_S2(i,j,k)^T = (k,0,i,0,j,1,k,0)^T
-@end group
-@end example
-@end ifnottex
-
-@noindent To ensure that the scattering functions have the same dimensionality, we
-complete the first function with zeroes
-(this is a CLooG @value{VERSION} and previous versions requirement,
-it should be removed in a future version, don't worry it's absolutely legal !):
-
-@tex
-$$
-\hbox{$ \cases{ \theta _{S1}(i,j)^T    &$=  (i,0,i,0,j,0,0,0)^T$\cr
-                \theta _{S2}(i,j,k)^T  &$=  (k,0,i,0,j,1,k,0)^T$}$}
-$$
-@end tex
-

-T_S1(i,j)^T   = (i,0,i,0,j,0,0,0)^T
-T_S2(i,j,k)^T = (k,0,i,0,j,1,k,0)^T
-@end group
-@end example

-@chapter Using the CLooG Library
-The CLooG Library was implemented to allow the user to call CLooG
-directly from his programs, without file accesses or system calls. The
-user only needs to link his programs with C libraries. The CLooG
-library mainly provides one function (@code{cloog_clast_create_from_input})
-which takes as input the problem
-description with some options, and returns the data structure corresponding
-to the generated code (a @code{struct clast_stmt} structure)
-which is more or less an abstract syntax tree.
-The user can work with this data structure and/or use
-our pretty printing function to write the final code in either C or FORTRAN.
-Some other functions are provided for convenience reasons.
-These functions as well as the data structures are described in this section.

-@example
-@group
-CloogState *cloog_state_malloc(void);
-void cloog_state_free(CloogState *state);
-@end group
-@end example
-
-@noindent The @code{CloogState} structure is (implicitly) needed to perform
-any CLooG operation.  It should be created using @code{cloog_state_malloc}
-before any other CLooG objects are created and destroyed using
-@code{cloog_state_free} after all objects have been freed.
-It is allowed to use more than one @code{CloogState} structure at
-the same time, but an object created within the state of a one
-@code{CloogState} structure is not allowed to interact with an object
-created within the state of an other @code{CloogState} structure.
-
-
-@node CloogMatrix
-@subsection CloogMatrix
-
-@noindent The @code{CloogMatrix} structure is equivalent to the PolyLib
-@code{Matrix} data structure (@pxref{Wil93}). This structure is devoted to
-represent a set of constraints.
-
-@example
-@group
-struct cloogmatrix
-@{ unsigned NbRows ;    /* Number of rows. */
-  unsigned NbColumns ; /* Number of columns. */
-  cloog_int_t **p;     /* Array of pointers to the matrix rows. */
-  cloog_int_t *p_Init; /* Matrix rows contiguously in memory. */
-@};
-typedef struct cloogmatrix CloogMatrix;
-
-CloogMatrix *cloog_matrix_alloc(unsigned NbRows, unsigned NbColumns);
-void cloog_matrix_print(FILE *foo, CloogMatrix *m);
-void cloog_matrix_free(CloogMatrix *matrix);
-@end group
-@end example
-
-@noindent The whole matrix is stored in memory row after row at the
-@code{p_Init} address. @code{p} is an array of pointers where
-@code{p[i]} points to the first element of the @math{i^{th}} row.
-@code{NbRows} and @code{NbColumns} are respectively the number of
-rows and columns of the matrix. 
-Each row corresponds to a constraint. The first element of each row is an
-equality/inequality tag. The
-constraint is an equality @math{p(x) = 0} if the first element is 0, but it is
-an inequality @math{p(x) \geq 0} if the first element is 1.
-The next elements are the coefficients of the unknowns,
-followed by the coefficients of the parameters, and finally the constant term.
-For instance, the following three constraints:
-
-@tex

-A @code{clast_assignment} assigns the value given by
-the @code{clast_expr} @code{RHS} to a variable named @code{LHS}.
-
-@noindent
-A @code{clast_block} groups a list of statements into one statement.
-These statements are only generated if the @code{block} option is set,
-@pxref{Statement Block} and @ref{CloogOptions}.
-

-A @code{clast_user_stmt} represents a call to a statement specified
-by the user, @pxref{CloogStatement}.
-@code{substitutions} is a list of @code{clast_assignment} statements
-assigning an expression in terms of the scattering dimensions to
-each of the original iterators in the original order.
-The @code{LHS}s of these assignments are left blank (@code{NULL}).
-The @code{domain} is set to @code{NULL} if the @code{save_domains} option

-of values for the scattering dimensions
-for which this instance of the user statement is executed.
-Note that unless the @code{noscalars} option has been set, the
-constant scattering dimensions may have been removed from this set.
-
-@noindent
-A @code{clast_for} represents a for loop, iterating @code{body} for each
-value of @code{iterator} between @code{LB} and @code{UB} in steps
-of size @code{stride}.
-The @code{domain} is set to @code{NULL} if the @code{save_domains} option is not
-set.  Otherwise, it is set to the set of values for the scattering dimensions
-for which a user statement is executed inside this @code{clast_for}.  Note that
-unless the @code{noscalars} option has been set, the constant scattering
-dimensions may have been removed from this set.
-
-@noindent
-A @code{clast_guard} represents the guarded execution of the @code{then}
-(list of) statement(s) by a conjunction of @code{n} (in)equalities.
-Each (in)equality is represented by a @code{clast_equation}.
-@example
-struct clast_equation @{
-    struct clast_expr *	LHS;
-    struct clast_expr *	RHS;
-    int			sign;
-@};

-@noindent
-The condition expressed by a @code{clast_equation} is
-@code{LHS <= RHS}, @code{LHS == RHS} or @code{LHS >= RHS}
-depending on whether @code{sign} is less than zero, equal
-to zero, or greater than zero.
-
-The dynamic type of a @code{clast_stmt} can be determined
-using the macro @code{CLAST_STMT_IS_A(stmt,type)},
-where @code{stmt} is a pointer to a @code{clast_stmt}
-and @code{type} is one of @code{stmt_root}, @code{stmt_ass},
-@code{stmt_user}, @code{stmt_block}, @code{stmt_for} or
-@code{stmt_guard}.
-Users are allowed to define their own statement types by
-assigning the @code{op} field of the statements a pointer
-to a @code{clast_stmt_op} structure.
-@example
-struct clast_stmt_op @{
-    void (*free)(struct clast_stmt *);
-@};
-@end example
-@noindent
-The @code{free} field of this structure should point
-to a function that frees the user defined statement.
-
-@noindent
-A @code{clast_expr} can be an identifier, a term,
-a binary expression or a reduction.
-@example
-enum clast_expr_type @{
-    clast_expr_name,
-    clast_expr_term,
-    clast_expr_bin,
-    clast_expr_red
-@};

-    enum clast_expr_type type;
-@};
-void free_clast_expr(struct clast_expr *e);
-@end example
-
-@noindent
-Identifiers are of subtype @code{clast_name}.
-@example
-struct clast_name @{
-    struct clast_expr	expr;
-    const char *	name;
-@};
-struct clast_name *new_clast_name(const char *name);
-void free_clast_name(struct clast_name *t);
-@end example
-@noindent
-The character string pointed to by @code{name} is
-assumed to be part of the @code{CloogNames} structure
-in the root of the clast as is therefore not copied.
-
-@noindent
-Terms are of type @code{clast_term}.
-@example
-struct clast_term @{
-    struct clast_expr   expr;
-    cloog_int_t         val;
-    struct clast_expr  *var;
-@};
-struct clast_term *new_clast_term(cloog_int_t c, struct clast_expr *v);
-void free_clast_term(struct clast_term *t);
-@end example
-@noindent
-If @code{var} is set to @code{NULL}, then the term represents
-the integer value @code{val}.  Otherwise, it represents
-the term @code{val * var}.
-@code{new_clast_term} simply copies the @code{v} pointer
-without copying the underlying @code{clast_expr}.
-@code{free_clast_term}, on the other hand, recursively frees
-@code{var}.

-@node Retrieving version information
-@section Retrieving version information
-CLooG provides static and dynamic version checks to assist on
-including a compatible version of the library.
-A static version check at compile time can be achieved by
-querying the version constants defined in @code{version.h}:
-
-@itemize @bullet
-@item @code{CLOOG_VERSION_MAJOR}
-@item @code{CLOOG_VERSION_MINOR}
-@item @code{CLOOG_VERSION_REVISION}
-@end itemize
-
-This way it is possible to ensure the included headers are of the
-correct version. It is still possible that the installed CLooG
-library version differs from the installed headers.
-In order to avoid this, a dynamic version check is provided with
-the functions:
-
-@example
-@group
-int cloog_version_major(void);
-int cloog_version_minor(void);
-int cloog_version_revision(void);
-@end group
-@end example
-
-By using both the static and the dynamic version check, it is possible
-to match CLooG's header version with the library's version.
-
-@node Example of Library Utilization
-@section Example of Library Utilization
-Here is a basic example showing how it is possible to use the CLooG library,
-assuming that a standard installation has been done.
-The following C program reads a CLooG input file on the standard input,
-then prints the solution on the standard output.
-Options are preselected to the default values of the CLooG software.
-This example is provided in the @code{example} directory of the
-CLooG distribution.
-@example
-/* example.c */
-# include <stdio.h>
-# include <cloog/cloog.h>
-
-int main()
-@{
-  CloogState *state;
-  CloogInput *input;
-  CloogOptions * options ;
-  struct clast_stmt *root;
-  
-  /* Setting options and reading program informations. */
-  state = cloog_state_malloc();
-  options = cloog_options_malloc(state);
-  input = cloog_input_read(stdin, options);
-
-  /* Generating and printing the code. */
-  root = cloog_clast_create_from_input(input, options);
-  clast_pprint(stdout, root, 0, options);
-
-  cloog_clast_free(root);
-  cloog_options_free(options) ;
-  cloog_state_free(state);
-  return 0;
-@}
-@end example
-
-@noindent The compilation command could be:
-@example
-gcc example.c -lcloog -o example
-@end example
-@noindent A calling command with the input file test.cloog could be:
-@example
-more test.cloog | ./example
-@end example

-First of all, it would be very kind to refer the following paper in any
-publication that result from the use of the CLooG software or its library,
-@pxref{Bas04} (a bibtex entry is provided behind the title page of this
-manual, along with copyright notice, and in the CLooG home
-@code{http://www.CLooG.org}.

-
-Note, though, that if you link CLooG against a GPL library such
-as the PolyLib backend, then the combination becomes GPL too.
-In particular, a CLooG library based on the PolyLib backend
-is GPL version 2 only.
-Since the isl backend is LGPL, linking against it does not affect
-the license of CLooG.
-
-
-@node Requirements
-@section Requirements
-
-CLooG can be used with one of two possible backends,
-one using isl and one using PolyLib.
-The isl library is included in the CLooG distribution,
-while the PolyLib library needs to be obtained separately.
-On the other hand, isl requires GMP, while PolyLib can be
-compiled with or without the use of GMP.
-The user therefore needs to install at least one of
-PolyLib or GMP.
-
-@menu
-* PolyLib::
-* GMP Library::
-@end menu
-
-
-@node PolyLib
-@subsection PolyLib (optional)
-To successfully install CLooG with the PolyLib backend,
-the user first needs to install PolyLib
-version 5.22.1 or above (default 64 bits version is satisfying
-as well as 32 bits or GMP multiple precision version).
-Polylib can be downloaded freely
-at @code{http://icps.u-strasbg.fr/PolyLib/} or
-@code{http://www.irisa.fr/polylib/}. Once downloaded and unpacked
-(e.g. using the @samp{tar -zxvf polylib-5.22.3.tar.gz} command),
-the user can compile
-it by typing the following commands on the PolyLib's root directory:
-
-@itemize @bullet
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-Alternatively, the latest development version can be obtained from the
-git repository:
-@itemize @bullet
-@item @code{git clone git://repo.or.cz/polylib.git}
-@item @code{cd polylib}
-@item @code{./autogen.sh}
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-The PolyLib default installation is @code{/usr/local}. This directory may
-not be inside your library path. To fix the problem, the user should set
-@example
-export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
-@end example
-@noindent if your shell is, e.g., bash or
-@example
-setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/usr/local/lib
-@end example
-@noindent if your shell is, e.g., tcsh. Add the line to your .bashrc or .tcshrc (or
-whatever convenient file) to make this change permanent. Another solution
-is to ask PolyLib to install in the standard path by using the prefix
-option of the configure script:
-@samp{./configure --prefix=/usr}.
-
-CLooG makes intensive calls to polyhedral operations, and PolyLib
-functions do the job. Polylib is a free library written in C for the
-manipulation of polyhedra. The library is operating on objects like
-vectors, matrices, lattices, polyhedra, Z-polyhedra, unions of
-polyhedra and a lot of other intermediary structures. It provides
-functions for all the important operations on these structures. 
-
-@node GMP Library
-@subsection GMP Library (optional)
-
-To be able to deal with insanely large coefficient, the user will need to
-install the GNU Multiple Precision Library (GMP for short) version 4.1.4
-or above. It can be freely downloaded from @code{http://www.swox.com/gmp}.
-Note that the isl backend currently requires GMP.
-The user can compile GMP by typing the following commands on the GMP root
-directory:
-
-@itemize @bullet
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-The GMP default installation is @code{/usr/local}, the same method to
-fix a library path problem applies as with PolyLib (@pxref{PolyLib}).
-
-If you want to use the PolyLib backend, then
-PolyLib has to be built using the GMP library by specifying the option
-@samp{--with-libgmp=PATH_TO_GMP} to the PolyLib configure script
-(where @code{PATH_TO_GMP} is @code{/usr/local} if you did not change the GMP
-installation directory). Then you have to set the convenient CLooG configure
-script options to build the GMP version (@pxref{Optional Features}).
-
-
-@node Basic Installation
-@section CLooG Basic Installation
-
-Once downloaded and unpacked
-(e.g. using the @samp{tar -zxvf cloog-@value{VERSION}.tar.gz} command),
-you can compile CLooG by typing the following commands on the CLooG's root
-directory:
-
-@itemize @bullet
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-Alternatively, the latest development version can be obtained from the
-git repository:
-@itemize @bullet
-@item @code{git clone git://repo.or.cz/cloog.git}
-@item @code{cd cloog}
-@item @code{./get_submodules.sh}
-@item @code{./autogen.sh}
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-Depending on which backend you want to use and where they
-are located, you may need to pass some
-options to the configure script, @pxref{Optional Features}.
-
-The program binaries and object files can be removed from the
-source code directory by typing @code{make clean}. To also remove the
-files that the @code{configure} script created (so you can compile the
-package for a different kind of computer) type @code{make distclean}.
-
-Both the CLooG software and library have been successfully compiled
-on the following systems:
-@itemize @bullet
-@item PC's under Linux, with the @code{gcc} compiler,
-@item PC's under Windows (Cygwin), with the @code{gcc} compiler,
-@item Sparc and UltraSparc Stations, with the @code{gcc} compiler.
-@end itemize
-
-@node Optional Features 
-@section Optional Features  
-The @code{configure} shell script attempts to guess correct values for
-various system-dependent variables and user options used during compilation.
-It uses those values to create the @code{Makefile}. Various user options
-are provided by the CLooG's configure script. They are summarized in the
-following list and may be printed by typing @code{./configure --help} in the
-CLooG top-level directory.
-
-@itemize @bullet
-@item By default, the installation directory is @code{/usr/local}:
-@code{make install} will install the package's files in
-@code{/usr/local/bin}, @code{/usr/local/lib} and @code{/usr/local/include}.
-The user can specify an installation prefix other than @code{/usr/local} by
-giving @code{configure} the option @code{--prefix=PATH}.
-
-@item By default, the isl backend will use the version of isl
-that is @code{bundled} together with CLooG.
-Using the @code{--with-isl} option of @code{configure}
-the user can specify that @code{no} isl,
-a previously installed (@code{system}) isl or a @code{build} isl
-should be used.
-In the latter case, the user should also specify the build location
-using @code{--with-isl-builddir=PATH}.
-In case of an installed isl,
-the installation location can be specified using the
-@code{--with-isl-prefix=PATH} and
-@code{--with-isl-exec-prefix=PATH} options of @code{configure}.
-
-@item By default, the PolyLib backend will use an installed
-(@code{system}) PolyLib, if any.
-The installation location can be specified using the
-@code{--with-polylib-prefix=PATH} and
-@code{--with-polylib-exec-prefix=PATH} options of @code{configure}.
-Using the @code{--with-polylib} option of @code{configure}
-the user can specify that @code{no} PolyLib or a @code{build} PolyLib
-should be used.
-In the latter case, the user should also specify the build location
-using @code{--with-polylib-builddir=PATH}.
-
-@item By default, the PolyLib backend of CLooG is built
-in 64bits version if such version of the
-PolyLib is found by @code{configure}. If the only existing version of the
-PolyLib is the 32bits or if the user give to @code{configure} the option
-@code{--with-bits=32}, the 32bits version of CLooG will be compiled. In the
-same way, the option @code{--with-bits=gmp} have to be used to build
-the multiple precision version.
-
-@item By default, @code{configure} will look for the GMP library
-(necessary to build the multiple precision version) in standard
-locations. If necessary, the user can specify the GMP path by giving
-@code{configure} the option @code{--with-gmp-prefix=PATH} and/or
-@code{--with-gmp-exec-prefix=PATH}.
-
-@item By default, the OpenScop Library (osl) support is not enabled.
-@c @code{configure} will use the bundled OpenScop Library (osl).
-Using the @code{--with-osl} option of @code{configure}
-the user can specify that @code{no} osl,
-a previously installed (@code{system}) osl, a @code{bundled} osl, or a
-@code{build} osl should be used.
-In the latter case, the user should also specify the build location
-using @code{--with-osl-builddir=PATH}.
-In case of an installed osl,
-the installation location can be specified using the
-@code{--with-osl-prefix=PATH} and
-@code{--with-osl-exec-prefix=PATH} options of @code{configure}.
-@end itemize
-
-@node Uninstallation 
-@section Uninstallation  
-The user can easily remove the CLooG software and library from his system
-by typing (as root if necessary) from the CLooG top-level directory
-@code{make uninstall}.
-
-@c %  **************************** DOCUMENTATION ******************************
-@node Documentation
-@chapter Documentation
-The CLooG distribution provides several documentation sources. First, the
-source code itself is as documented as possible. The code comments use a
-Doxygen-compatible presentation (something similar to what JavaDoc does for
-JAVA). The user may install Doxygen
-(see @code{http://www.stack.nl/~dimitri/doxygen}) to automatically
-generate a technical documentation by typing @code{make doc} or
-@code{doxygen ./autoconf/Doxyfile} at the CLooG top-level directory after
-running the configure script (@pxref{Installing}). Doxygen will generate
-documentation sources (in HTML, LaTeX and man) in the @code{doc/source}
-directory of the CLooG distribution.
-
-The Texinfo sources of the present document are also provided in the @code{doc}
-directory. You can build it in either DVI format (by typing
-@code{texi2dvi cloog.texi}) or PDF format
-(by typing @code{texi2pdf cloog.texi}) or HTML format
-(by typing @code{makeinfo --html cloog.texi}, using @code{--no-split}
-option to generate a single HTML file) or info format
-(by typing @code{makeinfo cloog.texi}).

-In this directory are presented various examples of how to use the CLooG
-library. For each case, you will need to edit the makefile file according to
-your system, in particular you will have to set where your CLooG library has
-been installed, and where are the CLooG header files. Don't forget to update
-your LD_LIBRARY_PATH environment variable to reach the CLooG library. If you
-performed the default installation of CLooG, the library is in /usr/local/lib
-thus you need to set LD_LIBRARY_PATH thanks to one of the following command:
-'setenv LD_LIBRARY_PATH /usr/local/lib' for tcsh-like shells, or
-'export LD_LIBRARY_PATH=/usr/local/lib' for bash-like shells.
-
-For any problem: <cedric.bastoul@inria.fr>.

-
-This example program creates a simple CLooG-like loop generation program in a
-few lines. The input problem has to be given on standard input. We can test it
-for instance by typing 'more FILE.cloog | ./example' (or example.exe under
-Cygwin).

- *   block, the stride is 1 (i.e. there is no stride), block is necessarily not
- *   NULL and inner is NULL.
- * - if the loop comes as a result of a cloog_loop_generate call, the domain

- *   (the last one: outer dimensions being considered as parameters), the stride
- *   may differ from one (this means that on the considered dimension, a step of
- *   'stride' must be considered between integral point, the first integral
- *   point to be considered being the lower bound of the loop), inner may differ
- *   from NULL, meaning that there are further dimensions and nesting levels in

-/* The CloogMatrix structure is equivalent to the PolyLib Matrix data structure
- * (see Wil93). This structure is devoted to represent a set of constraints.
- *
- * The whole matrix is stored in memory row after row at the p_Init address. p
- * is an array of pointers where p[i] points to the first element of the i^{th
- * row. NbRows and NbColumns are respectively the number of rows and columns of
- * the matrix. Each row corresponds to a constraint. The first element of each
- * row is an equality/inequality tag. The constraint is an equality p(x) = 0 if
- * the first element is 0, but it is an inequality p(x) \geq 0 if the first
- * element is 1. The next elements are the unknown coefficients, followed by
- * the parameter coefficients, then the constant term. For instance, the
- * following three constraints:
- *
- *     -i + m  = 0
- *     -j + n >= 0
- *  i + j - k >= 0
- *
- * would be represented by the following rows:
- *
- * # eq/in  i   j   k   m   n   cst
- *     0    0  -1   0   1   0    0
- *     1   -1   0   0   0   1    0
- *     1    1   1  -1   0   0    0
- *
- * To be able to provide different precision version (CLooG supports 32 bits,
- * 64 bits and arbitrary precision through the GMP library), the cloog_int_t
- * type depends on the configuration options (it may be long int for 32 bits
- * version, long long int for 64 bits version, and mpz_t for multiple precision
- * version). */

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-  CXX         C++ compiler command
-  CXXFLAGS    C++ compiler flags
-  CPP         C preprocessor
-  CXXCPP      C++ preprocessor

-% ===================================
-%
-% BibTeX `chicago' style file for BibTeX version 0.99c, LaTeX version 2.09
-% Place it in a file called chicago.bst in the BibTeX search path.
-% You need to include chicago.sty as a \documentstyle option.
-% (Placing it in the same directory as the LaTeX document should also work.)
-% This "chicago" style is based on newapa.bst (American Psych. Assoc.)
-% found at ymir.claremont.edu.
-%
-%   Citation format: (author-last-name year)
-%             (author-last-name and author-last-name year)
-%             (author-last-name, author-last-name, and author-last-name year)
-%             (author-last-name et al. year)
-%             (author-last-name)
-%             author-last-name (year)
-%             (author-last-name and author-last-name)
-%             (author-last-name et al.)
-%             (year) or (year,year)
-%             year or year,year
-%
-%   Reference list ordering: alphabetical by author or whatever passes
-%    for author in the absence of one.
-%
-% This BibTeX style has support for abbreviated author lists and for
-%    year-only citations.  This is done by having the citations
-%    actually look like
-%
-%    \citeauthoryear{full-author-info}{abbrev-author-info}{year}
-%
-% The LaTeX style has to have the following (or similar)

-% These TeX macro definitions are found in chicago.sty. Additional

-% so that, for example, you can list author's names without parentheses
-% if using a citation as a noun or object in a sentence.

-% Features of chicago.bst:
-% =======================
-%
-% - full names used in citations, but abbreviated citations are available
-%   (see above)
-% - if an entry has a "month", then the month and year are also printed
-%   as part of that bibitem.
-% - all conjunctions use "and" instead of "\&"
-% - major modification from Chicago Manual of Style (13th ed.) is that
-%   only the first author in a reference appears last name first-
-%   additional authors appear as J. Q. Public.
-% - pages are listed as "pp. xx-xx" in all entry types except
-%   article entries.
-% - book, inbook, and manual use "location: publisher" (or organization)
-%   for address and publisher. All other types list publishers separately.
-% - "pp." are used to identify page numbers for all entry types except
-%   articles.
-% - organization is used as a citation label if neither author nor editor
-%   is present (for manuals).
-% - "et al." is used for long author and editor lists, or when "others"
-%   is used.
-%
-% Modifications and bug fixes from newapa.bst:
-% ===========================================
-%
-%   - added month, year to bib entries if month is present
-%   - fixed bug with In proceedings, added necessary comma after title
-%   - all conjunctions changed to "and" from "\&"
-%   - fixed bug with author labels in my.full.label: "et al." now is
-%        generated when "others" is an author name
-%   - major modification from Chicago Manual of Style (13th ed.) is that
-%     only the first author in a reference appears last name first-
-%     additional authors appear as J. Q. Public.
-%   - pages are listed as "pp. xx-xx" in all entry types except
-%     article entries. Unnecessary (IMHO) "()" around page numbers
-%     were removed, and page numbers now don't end with a period.
-%   - created chicago.sty for use with this bibstyle (required).
-%   - fixed bugs in FUNCTION {format.vol.num.pages} for missing volume,
-%     number, and /or pages. Renamed to format.jour.vol.
-%   - fixed bug in formatting booktitles: additional period an error if
-%     book has a volume.
-%   - fixed bug: editors usually given redundant period before next clause
-%     (format.editors.dot) removed.
-%   - added label support for organizations, if both author and editor
-%     are missing (from alpha.bst). If organization is too long, then
-%     the key field is used for abbreviated citations.
-%   - In proceedings or books of several volumes, no comma was written
-%     between the "Volume x" and the page numbers (this was intentional
-%     in newapa.bst). Fixed.
-%   - Some journals may not have volumes/numbers, only month/year (eg.
-%     IEEE Computer). Fixed bug in article style that assumed volume/number
-%     was always present.

-% chicago.sty: Style file for use with bibtex style chicago.bst, for

-%
-% 'newapa.bst' was made from 'plain.bst', 'named.bst', and 'apalike.bst',
-% with lots of tweaking to make it look like APA style, along with tips
-% from Young Ryu and Brian Reiser's modifications of 'apalike.bst'.
-% newapa.sty formed the basis of this style, chicago.sty. Author-date
-% references in newapa.bst formed the basis for chicago.bst. Chicagoa.bst
-% supports annotations.
-%
-% Version 4 (August, 1992):
-% - fixed chicago.bst and chicagoa.bst to handle long author lists in
-%   sorting
-% - fixed chicago.bst and chicagoa.bst so that missing page numbers in
-%   ``article'' entries are handled correctly
-% - modified chicago.sty to format entries with 2nd and subsequent lines
-%   indented.
-%
-%   Citation format: (author-last-name year)
-%             (author-last-name and author-last-name year)
-%             (author-last-name et al. year)
-%             (author-last-name)
-%             author-last-name
-%             author-last-name (year)
-%             (author-last-name and author-last-name)
-%             (author-last-name et al.)
-%             (year) or (year,year)
-%             year or year,year
-%
-%   Reference list ordering: alphabetical by author or whatever passes
-%    for author in the absence of one.
-%
-% This BibTeX style has support for abbreviated author lists and for
-%    year-only citations.  This is done by having the citations
-%    actually look like
-%
-%    \citeauthoryear{full-author-info}{abbrev-author-info}{year}
-%
-% The LaTeX style has to have the following (or similar)
-%
-%     \let\@internalcite\cite
-%     \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}
-%     \def\fullciteA{\def\citeauthoryear##1##2##3{##1}\@internalcite}
-%     \def\shortcite{\def\citeauthoryear##1##2##3{##2, ##3}\@internalcite}

-%     \def\citeyear{\def\citeauthoryear##1##2##3{##3}\@internalcite}

-% This file implements citations for the ``chicago'' bibliography style.
-%  Place it in a file called chicago.sty in the TeX search path.
-%(Placing it in the same directory as the LaTeX document should also work.)
-%
-%    This file is a modification of the ``newapa'' LaTeX style,
-%    originally adapted by Steven Spencer from the ``apalike'' LaTeX style.
-%    It was originally modified by Stephen N. Spencer, with further
-%    modifications by Young U. Ryu.
-%
-% The ``chicago'' BibTeX bibliography style creates citations with labels:
-%       \citeauthoryear{author-info}{abbrev. author-info}{year}
-%
-% These labels are processed by the following LaTeX commands:
-%
-%  \cite{key}
-%    which produces citations with full author list and year.
-%    eg. (Brown 1978; Jarke, Turner, Stohl, et al. 1985)
-%  \citeNP{key}
-%    which produces citations with full author list and year, but without
-%    enclosing parentheses:
-%    eg. Brown 1978; Jarke, Turner and Stohl 1985
-%  \citeA{key}
-%    which produces citations with only the full author list.
-%    eg. (Brown; Jarke, Turner and Stohl)
-%  \citeANP{key}
-%    which produces citations with only the full author list, without
-%    parentheses eg. Brown; Jarke, Turner and Stohl
-%  \citeN{key}
-%    which produces citations with the full author list and year, but
-%    can be used as nouns in a sentence; no parentheses appear around
-%    the author names, but only around the year.
-%      eg. Shneiderman (1978) states that......
-%    \citeN should only be used for a single citation.
-%  \shortcite{key}
-%    which produces citations with abbreviated author list and year.
-%  \shortciteNP{key}
-%    which produces citations with abbreviated author list and year.
-%  \shortciteA{key}
-%    which produces only the abbreviated author list.
-%  \shortciteANP{key}
-%    which produces only the abbreviated author list.
-%  \shortciteN{key}
-%    which produces the abbreviated author list and year, with only the
-%    year in parentheses. Use with only one citation.
-%  \citeyear{key}
-%    which produces the year information only, within parentheses.
-%  \citeyearNP{key}
-%    which produces the year information only.
-%
-% Abbreviated author lists use the ``et al.'' construct.
-%
-% `NP' means `no parentheses'.
-%
-% This LaTeX style file must be used with the ``chicago'' or ``chicagoa''
-% (annotated chicago style) BibTeX styles.

-\section{Simple Hull}\label{s:simple hull}
-
-It is sometimes useful to have a single
-basic set or basic relation that contains a given set or relation.
-For rational sets, the obvious choice would be to compute the
-(rational) convex hull.  For integer sets, the obvious choice
-would be the integer hull.
-However, {\tt isl} currently does not support an integer hull operation
-and even if it did, it would be fairly expensive to compute.
-The convex hull operation is supported, but it is also fairly
-expensive to compute given only an implicit representation.
-
-Usually, it is not required to compute the exact integer hull,
-and an overapproximation of this hull is sufficient.
-The ``simple hull'' of a set is such an overapproximation
-and it is defined as the (inclusion-wise) smallest basic set
-that is described by constraints that are translates of
-the constraints in the input set.
-This means that the simple hull is relatively cheap to compute
-and that the number of constraints in the simple hull is no
-larger than the number of constraints in the input.
-\begin{definition}[Simple Hull of a Set]
-The {\em simple hull} of a set
-$S = \bigcup_{1 \le i \le v} S_i$, with
-$$
-S : \Z^n \to 2^{\Z^d} : \vec s \mapsto
-S(\vec s) =
-\left\{\, \vec x \in \Z^d \mid \exists \vec z \in \Z^e :
-\bigvee_{1 \le i \le v}
-A_i \vec x + B_i \vec s + D_i \vec z + \vec c_i \geq \vec 0 \,\right\}
-$$
-is the set
-$$
-H : \Z^n \to 2^{\Z^d} : \vec s \mapsto
-S(\vec s) =
-\left\{\, \vec x \in \Z^d \mid \exists \vec z \in \Z^e :
-\bigwedge_{1 \le i \le v}
-A_i \vec x + B_i \vec s + D_i \vec z + \vec c_i + \vec K_i \geq \vec 0
-\,\right\}
-,
-$$
-with $\vec K_i$ the (component-wise) smallest non-negative integer vectors
-such that $S \subseteq H$.
-\end{definition}
-The $\vec K_i$ can be obtained by solving a number of
-LP problems, one for each element of each $\vec K_i$.
-If any LP problem is unbounded, then the corresponding constraint
-is dropped.

-\section{Parametric Integer Programming}
-
-\subsection{Introduction}\label{s:intro}
-
-Parametric integer programming \shortcite{Feautrier88parametric}
-is used to solve many problems within the context of the polyhedral model.
-Here, we are mainly interested in dependence analysis \shortcite{Fea91}
-and in computing a unique representation for existentially quantified
-variables.  The latter operation has been used for counting elements
-in sets involving such variables
-\shortcite{BouletRe98,Verdoolaege2005experiences} and lies at the core
-of the internal representation of {\tt isl}.
-
-Parametric integer programming was first implemented in \texttt{PipLib}.
-An alternative method for parametric integer programming
-was later implemented in {\tt barvinok} \cite{barvinok-0.22}.
-This method is not based on Feautrier's algorithm, but on rational
-generating functions \cite{Woods2003short} and was inspired by the
-``digging'' technique of \shortciteN{DeLoera2004Three} for solving
-non-parametric integer programming problems.
-
-In the following sections, we briefly recall the dual simplex
-method combined with Gomory cuts and describe some extensions
-and optimizations.  The main algorithm is applied to a matrix
-data structure known as a tableau.  In case of parametric problems,
-there are two tableaus, one for the main problem and one for
-the constraints on the parameters, known as the context tableau.
-The handling of the context tableau is described in \autoref{s:context}.
-
-\subsection{The Dual Simplex Method}
-
-Tableaus can be represented in several slightly different ways.
-In {\tt isl}, the dual simplex method uses the same representation
-as that used by its incremental LP solver based on the \emph{primal}
-simplex method.  The implementation of this LP solver is based
-on that of {\tt Simplify} \shortcite{Detlefs2005simplify}, which, in turn,
-was derived from the work of \shortciteN{Nelson1980phd}.
-In the original \shortcite{Nelson1980phd}, the tableau was implemented
-as a sparse matrix, but neither {\tt Simplify} nor the current
-implementation of {\tt isl} does so.
-
-Given some affine constraints on the variables,
-$A \vec x + \vec b \ge \vec 0$, the tableau represents the relationship
-between the variables $\vec x$ and non-negative variables
-$\vec y = A \vec x + \vec b$ corresponding to the constraints.
-The initial tableau contains $\begin{pmatrix}
-\vec b & A
-\end{pmatrix}$ and expresses the constraints $\vec y$ in the rows in terms
-of the variables $\vec x$ in the columns.  The main operation defined
-on a tableau exchanges a column and a row variable and is called a pivot.
-During this process, some coefficients may become rational.
-As in the \texttt{PipLib} implementation,
-{\tt isl} maintains a shared denominator per row.
-The sample value of a tableau is one where each column variable is assigned
-zero and each row variable is assigned the constant term of the row.
-This sample value represents a valid solution if each constraint variable
-is assigned a non-negative value, i.e., if the constant terms of
-rows corresponding to constraints are all non-negative.
-
-The dual simplex method starts from an initial sample value that
-may be invalid, but that is known to be (lexicographically) no
-greater than any solution, and gradually increments this sample value
-through pivoting until a valid solution is obtained.
-In particular, each pivot exchanges a row variable
-$r = -n + \sum_i a_i \, c_i$ with negative
-sample value $-n$ with a column variable $c_j$
-such that $a_j > 0$.  Since $c_j = (n + r - \sum_{i\ne j} a_i \, c_i)/a_j$,
-the new row variable will have a positive sample value $n$.
-If no such column can be found, then the problem is infeasible.
-By always choosing the column that leads to the (lexicographically)
-smallest increment in the variables $\vec x$,
-the first solution found is guaranteed to be the (lexicographically)
-minimal solution \cite{Feautrier88parametric}.
-In order to be able to determine the smallest increment, the tableau
-is (implicitly) extended with extra rows defining the original
-variables in terms of the column variables.
-If we assume that all variables are non-negative, then we know
-that the zero vector is no greater than the minimal solution and
-then the initial extended tableau looks as follows.
-$$
-\begin{tikzpicture}
-\matrix (m) [matrix of math nodes]
-{
-& {} & 1 & \vec c \\
-\vec x && |(top)| \vec 0 & I \\
-\vec r && \vec b & |(bottom)|A \\
-};
-\begin{pgfonlayer}{background}
-\node (core) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)] {};
-\end{pgfonlayer}
-\end{tikzpicture}
-$$
-Each column in this extended tableau is lexicographically positive
-and will remain so because of the column choice explained above.
-It is then clear that the value of $\vec x$ will increase in each step.
-Note that there is no need to store the extra rows explicitly.
-If a given $x_i$ is a column variable, then the corresponding row
-is the unit vector $e_i$.  If, on the other hand, it is a row variable,
-then the row already appears somewhere else in the tableau.
-
-In case of parametric problems, the sign of the constant term
-may depend on the parameters.  Each time the constant term of a constraint row
-changes, we therefore need to check whether the new term can attain
-negative and/or positive values over the current set of possible
-parameter values, i.e., the context.
-If all these terms can only attain non-negative values, the current
-state of the tableau represents a solution.  If one of the terms
-can only attain non-positive values and is not identically zero,
-the corresponding row can be pivoted.
-Otherwise, we pick one of the terms that can attain both positive
-and negative values and split the context into a part where
-it only attains non-negative values and a part where it only attains
-negative values.
-
-\subsection{Gomory Cuts}
-
-The solution found by the dual simplex method may have
-non-integral coordinates.  If so, some rational solutions
-(including the current sample value), can be cut off by
-applying a (parametric) Gomory cut.
-Let $r = b(\vec p) + \sp {\vec a} {\vec c}$ be the row
-corresponding to the first non-integral coordinate of $\vec x$,
-with $b(\vec p)$ the constant term, an affine expression in the
-parameters $\vec p$, i.e., $b(\vec p) = \sp {\vec f} {\vec p} + g$.
-Note that only row variables can attain
-non-integral values as the sample value of the column variables is zero.
-Consider the expression
-$b(\vec p) - \ceil{b(\vec p)} + \sp {\fract{\vec a}} {\vec c}$,
-with $\ceil\cdot$ the ceiling function and $\fract\cdot$ the
-fractional part.  This expression is negative at the sample value
-since $\vec c = \vec 0$ and $r = b(\vec p)$ is fractional, i.e.,
-$\ceil{b(\vec p)} > b(\vec p)$.  On the other hand, for each integral
-value of $r$ and $\vec c \ge 0$, the expression is non-negative
-because $b(\vec p) - \ceil{b(\vec p)} > -1$.
-Imposing this expression to be non-negative therefore does not
-invalidate any integral solutions, while it does cut away the current
-fractional sample value.  To be able to formulate this constraint,
-a new variable $q = \floor{-b(\vec p)} = - \ceil{b(\vec p)}$ is added
-to the context.  This integral variable is uniquely defined by the constraints
-$0 \le -d \, b(\vec p) - d \, q \le d - 1$, with $d$ the common
-denominator of $\vec f$ and $g$.  In practice, the variable
-$q' = \floor{\sp {\fract{-f}} {\vec p} + \fract{-g}}$ is used instead
-and the coefficients of the new constraint are adjusted accordingly.
-The sign of the constant term of this new constraint need not be determined
-as it is non-positive by construction.
-When several of these extra context variables are added, it is important
-to avoid adding duplicates.
-Recent versions of {\tt PipLib} also check for such duplicates.
-
-\subsection{Negative Unknowns and Maximization}
-
-There are two places in the above algorithm where the unknowns $\vec x$
-are assumed to be non-negative: the initial tableau starts from
-sample value $\vec x = \vec 0$ and $\vec c$ is assumed to be non-negative
-during the construction of Gomory cuts.
-To deal with negative unknowns, \shortciteN[Appendix A.2]{Fea91}
-proposed to use a ``big parameter'', say $M$, that is taken to be
-an arbitrarily large positive number.  Instead of looking for the
-lexicographically minimal value of $\vec x$, we search instead
-for the lexicographically minimal value of $\vec x' = \vec M + \vec x$.
-The sample value $\vec x' = \vec 0$ of the initial tableau then
-corresponds to $\vec x = -\vec M$, which is clearly not greater than
-any potential solution.  The sign of the constant term of a row
-is determined lexicographically, with the coefficient of $M$ considered
-first.  That is, if the coefficient of $M$ is not zero, then its sign
-is the sign of the entire term.  Otherwise, the sign is determined
-by the remaining affine expression in the parameters.
-If the original problem has a bounded optimum, then the final sample
-value will be of the form $\vec M + \vec v$ and the optimal value
-of the original problem is then $\vec v$.
-Maximization problems can be handled in a similar way by computing
-the minimum of $\vec M - \vec x$.
-
-When the optimum is unbounded, the optimal value computed for
-the original problem will involve the big parameter.
-In the original implementation of {\tt PipLib}, the big parameter could
-even appear in some of the extra variables $\vec q$ created during
-the application of a Gomory cut.  The final result could then contain
-implicit conditions on the big parameter through conditions on such
-$\vec q$ variables.  This problem was resolved in later versions
-of {\tt PipLib} by taking $M$ to be divisible by any positive number.
-The big parameter can then never appear in any $\vec q$ because
-$\fract {\alpha M } = 0$.  It should be noted, though, that an unbounded
-problem usually (but not always)
-indicates an incorrect formulation of the problem.
-
-The original version of {\tt PipLib} required the user to ``manually''
-add a big parameter, perform the reformulation and interpret the result
-\shortcite{Feautrier02}.  Recent versions allow the user to simply
-specify that the unknowns may be negative or that the maximum should
-be computed and then these transformations are performed internally.
-Although there are some application, e.g.,
-that of \shortciteN{Feautrier92multi},
-where it is useful to have explicit control over the big parameter,
-negative unknowns and maximization are by far the most common applications
-of the big parameter and we believe that the user should not be bothered
-with such implementation issues.
-The current version of {\tt isl} therefore does not
-provide any interface for specifying big parameters.  Instead, the user
-can specify whether a maximum needs to be computed and no assumptions
-are made on the sign of the unknowns.  Instead, the sign of the unknowns
-is checked internally and a big parameter is automatically introduced when
-needed.  For compatibility with {\tt PipLib}, the {\tt isl\_pip} tool
-does explicitly add non-negativity constraints on the unknowns unless
-the \verb+Urs_unknowns+ option is specified.
-Currently, there is also no way in {\tt isl} of expressing a big
-parameter in the output.  Even though
-{\tt isl} makes the same divisibility assumption on the big parameter
-as recent versions of {\tt PipLib}, it will therefore eventually
-produce an error if the problem turns out to be unbounded.
-
-\subsection{Preprocessing}
-
-In this section, we describe some transformations that are
-or can be applied in advance to reduce the running time
-of the actual dual simplex method with Gomory cuts.
-
-\subsubsection{Feasibility Check and Detection of Equalities}
-
-Experience with the original {\tt PipLib} has shown that Gomory cuts
-do not perform very well on problems that are (non-obviously) empty,
-i.e., problems with rational solutions, but no integer solutions.
-In {\tt isl}, we therefore first perform a feasibility check on
-the original problem considered as a non-parametric problem
-over the combined space of unknowns and parameters.
-In fact, we do not simply check the feasibility, but we also
-check for implicit equalities among the integer points by computing
-the integer affine hull.  The algorithm used is the same as that
-described in \autoref{s:GBR} below.
-Computing the affine hull is fairly expensive, but it can
-bring huge benefits if any equalities can be found or if the problem
-turns out to be empty.
-
-\subsubsection{Constraint Simplification}
-
-If the coefficients of the unknown and parameters in a constraint
-have a common factor, then this factor should be removed, possibly
-rounding down the constant term.  For example, the constraint
-$2 x - 5 \ge 0$ should be simplified to $x - 3 \ge 0$.
-{\tt isl} performs such simplifications on all sets and relations.
-Recent versions of {\tt PipLib} also perform this simplification
-on the input.
-
-\subsubsection{Exploiting Equalities}\label{s:equalities}
-
-If there are any (explicit) equalities in the input description,
-{\tt PipLib} converts each into a pair of inequalities.
-It is also possible to write $r$ equalities as $r+1$ inequalities
-\shortcite{Feautrier02}, but it is even better to \emph{exploit} the
-equalities to reduce the dimensionality of the problem.
-Given an equality involving at least one unknown, we pivot
-the row corresponding to the equality with the column corresponding
-to the last unknown with non-zero coefficient.  The new column variable
-can then be removed completely because it is identically zero,
-thereby reducing the dimensionality of the problem by one.
-The last unknown is chosen to ensure that the columns of the initial
-tableau remain lexicographically positive.  In particular, if
-the equality is of the form $b + \sum_{i \le j} a_i \, x_i = 0$ with
-$a_j \ne 0$, then the (implicit) top rows of the initial tableau
-are changed as follows
-$$
-\begin{tikzpicture}
-\matrix [matrix of math nodes]
-{
- & {} & |(top)| 0 & I_1 & |(j)| &  \\
-j && 0 & & 1 & \\
-  && 0 & & & |(bottom)|I_2 \\
-};
-\node[overlay,above=2mm of j,anchor=south]{j};
-\begin{pgfonlayer}{background}
-\node (m) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)] {};
-\end{pgfonlayer}
-\begin{scope}[xshift=4cm]
-\matrix [matrix of math nodes]
-{
- & {} & |(top)| 0 & I_1 &  \\
-j && |(left)| -b/a_j & -a_i/a_j & \\
-  && 0 & & |(bottom)|I_2 \\
-};
-\begin{pgfonlayer}{background}
-\node (m2) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)(left)] {};
-\end{pgfonlayer}
-\end{scope}
- \draw [shorten >=7mm,-to,thick,decorate,
-        decoration={snake,amplitude=.4mm,segment length=2mm,
-                    pre=moveto,pre length=5mm,post length=8mm}]
-   (m) -- (m2);
-\end{tikzpicture}
-$$
-Currently, {\tt isl} also eliminates equalities involving only parameters
-in a similar way, provided at least one of the coefficients is equal to one.
-The application of parameter compression (see below)
-would obviate the need for removing parametric equalities.
-
-\subsubsection{Offline Symmetry Detection}\label{s:offline}
-
-Some problems, notably those of \shortciteN{Bygde2010licentiate},
-have a collection of constraints, say
-$b_i(\vec p) + \sp {\vec a} {\vec x} \ge 0$,
-that only differ in their (parametric) constant terms.
-These constant terms will be non-negative on different parts
-of the context and this context may have to be split for each
-of the constraints.  In the worst case, the basic algorithm may
-have to consider all possible orderings of the constant terms.
-Instead, {\tt isl} introduces a new parameter, say $u$, and
-replaces the collection of constraints by the single
-constraint $u + \sp {\vec a} {\vec x} \ge 0$ along with
-context constraints $u \le b_i(\vec p)$.
-Any solution to the new system is also a solution
-to the original system since
-$\sp {\vec a} {\vec x} \ge -u \ge -b_i(\vec p)$.
-Conversely, $m = \min_i b_i(\vec p)$ satisfies the constraints
-on $u$ and therefore extends a solution to the new system.
-It can also be plugged into a new solution.
-See \autoref{s:post} for how this substitution is currently performed
-in {\tt isl}.
-The method described in this section can only detect symmetries
-that are explicitly available in the input.
-See \autoref{s:online} for the detection
-and exploitation of symmetries that appear during the course of
-the dual simplex method.
-
-\subsubsection{Parameter Compression}\label{s:compression}
-
-It may in some cases be apparent from the equalities in the problem
-description that there can only be a solution for a sublattice
-of the parameters.  In such cases ``parameter compression''
-\shortcite{Meister2004PhD,Meister2008} can be used to replace
-the parameters by alternative ``dense'' parameters.
-For example, if there is a constraint $2x = n$, then the system
-will only have solutions for even values of $n$ and $n$ can be replaced
-by $2n'$.  Similarly, the parameters $n$ and $m$ in a system with
-the constraint $2n = 3m$ can be replaced by a single parameter $n'$
-with $n=3n'$ and $m=2n'$.
-It is also possible to perform a similar compression on the unknowns,
-but it would be more complicated as the compression would have to
-preserve the lexicographical order.  Moreover, due to our handling
-of equalities described above there should be
-no need for such variable compression.
-Although parameter compression has been implemented in {\tt isl},
-it is currently not yet used during parametric integer programming.
-
-\subsection{Postprocessing}\label{s:post}
-
-The output of {\tt PipLib} is a quast (quasi-affine selection tree).
-Each internal node in this tree corresponds to a split of the context
-based on a parametric constant term in the main tableau with indeterminate
-sign.  Each of these nodes may introduce extra variables in the context
-corresponding to integer divisions.  Each leaf of the tree prescribes
-the solution in that part of the context that satisfies all the conditions
-on the path leading to the leaf.
-Such a quast is a very economical way of representing the solution, but
-it would not be suitable as the (only) internal representation of
-sets and relations in {\tt isl}.  Instead, {\tt isl} represents
-the constraints of a set or relation in disjunctive normal form.
-The result of a parametric integer programming problem is then also
-converted to this internal representation.  Unfortunately, the conversion
-to disjunctive normal form can lead to an explosion of the size
-of the representation.
-In some cases, this overhead would have to be paid anyway in subsequent
-operations, but in other cases, especially for outside users that just
-want to solve parametric integer programming problems, we would like
-to avoid this overhead in future.  That is, we are planning on introducing
-quasts or a related representation as one of several possible internal
-representations and on allowing the output of {\tt isl\_pip} to optionally
-be printed as a quast.
-
-Currently, {\tt isl} also does not have an internal representation
-for expressions such as $\min_i b_i(\vec p)$ from the offline
-symmetry detection of \autoref{s:offline}.
-Assume that one of these expressions has $n$ bounds $b_i(\vec p)$.
-If the expression
-does not appear in the affine expression describing the solution,
-but only in the constraints, and if moreover, the expression
-only appears with a positive coefficient, i.e.,
-$\min_i b_i(\vec p) \ge f_j(\vec p)$, then each of these constraints
-can simply be reduplicated $n$ times, once for each of the bounds.
-Otherwise, a conversion to disjunctive normal form
-leads to $n$ cases, each described as $u = b_i(\vec p)$ with constraints
-$b_i(\vec p) \le b_j(\vec p)$ for $j > i$
-and
-$b_i(\vec p)  < b_j(\vec p)$ for $j < i$.
-Note that even though this conversion leads to a size increase
-by a factor of $n$, not detecting the symmetry could lead to
-an increase by a factor of $n!$ if all possible orderings end up being
-considered.
-
-\subsection{Context Tableau}\label{s:context}
-
-The main operation that a context tableau needs to provide is a test
-on the sign of an affine expression over the elements of the context.
-This sign can be determined by solving two integer linear feasibility
-problems, one with a constraint added to the context that enforces
-the expression to be non-negative and one where the expression is
-negative.  As already mentioned by \shortciteN{Feautrier88parametric},
-any integer linear feasibility solver could be used, but the {\tt PipLib}
-implementation uses a recursive call to the dual simplex with Gomory
-cuts algorithm to determine the feasibility of a context.
-In {\tt isl}, two ways of handling the context have been implemented,
-one that performs the recursive call and one, used by default, that
-uses generalized basis reduction.
-We start with some optimizations that are shared between the two
-implementations and then discuss additional details of each of them.
-
-\subsubsection{Maintaining Witnesses}\label{s:witness}
-
-A common feature of both integer linear feasibility solvers is that
-they will not only say whether a set is empty or not, but if the set
-is non-empty, they will also provide a \emph{witness} for this result,
-i.e., a point that belongs to the set.  By maintaining a list of such
-witnesses, we can avoid many feasibility tests during the determination
-of the signs of affine expressions.  In particular, if the expression
-evaluates to a positive number on some of these points and to a negative
-number on some others, then no feasibility test needs to be performed.
-If all the evaluations are non-negative, we only need to check for the
-possibility of a negative value and similarly in case of all
-non-positive evaluations.  Finally, in the rare case that all points
-evaluate to zero or at the start, when no points have been collected yet,
-one or two feasibility tests need to be performed depending on the result
-of the first test.
-
-When a new constraint is added to the context, the points that
-violate the constraint are temporarily removed.  They are reconsidered
-when we backtrack over the addition of the constraint, as they will
-satisfy the negation of the constraint.  It is only when we backtrack
-over the addition of the points that they are finally removed completely.
-When an extra integer division is added to the context,
-the new coordinates of the
-witnesses can easily be computed by evaluating the integer division.
-The idea of keeping track of witnesses was first used in {\tt barvinok}.
-
-\subsubsection{Choice of Constant Term on which to Split}
-
-Recall that if there are no rows with a non-positive constant term,
-but there are rows with an indeterminate sign, then the context
-needs to be split along the constant term of one of these rows.
-If there is more than one such row, then we need to choose which row
-to split on first.  {\tt PipLib} uses a heuristic based on the (absolute)
-sizes of the coefficients.  In particular, it takes the largest coefficient
-of each row and then selects the row where this largest coefficient is smaller
-than those of the other rows.
-
-In {\tt isl}, we take that row for which non-negativity of its constant
-term implies non-negativity of as many of the constant terms of the other
-rows as possible.  The intuition behind this heuristic is that on the
-positive side, we will have fewer negative and indeterminate signs,
-while on the negative side, we need to perform a pivot, which may
-affect any number of rows meaning that the effect on the signs
-is difficult to predict.  This heuristic is of course much more
-expensive to evaluate than the heuristic used by {\tt PipLib}.
-More extensive tests are needed to evaluate whether the heuristic is worthwhile.

-\subsubsection{Dual Simplex + Gomory Cuts}
-
-When a new constraint is added to the context, the first steps
-of the dual simplex method applied to this new context will be the same
-or at least very similar to those taken on the original context, i.e.,
-before the constraint was added.  In {\tt isl}, we therefore apply
-the dual simplex method incrementally on the context and backtrack
-to a previous state when a constraint is removed again.
-An initial implementation that was never made public would also
-keep the Gomory cuts, but the current implementation backtracks
-to before the point where Gomory cuts are added before adding
-an extra constraint to the context.
-Keeping the Gomory cuts has the advantage that the sample value
-is always an integer point and that this point may also satisfy
-the new constraint.  However, due to the technique of maintaining
-witnesses explained above,
-we would not perform a feasibility test in such cases and then
-the previously added cuts may be redundant, possibly resulting
-in an accumulation of a large number of cuts.
-
-If the parameters may be negative, then the same big parameter trick
-used in the main tableau is applied to the context.  This big parameter
-is of course unrelated to the big parameter from the main tableau.
-Note that it is not a requirement for this parameter to be ``big'',
-but it does allow for some code reuse in {\tt isl}.
-In {\tt PipLib}, the extra parameter is not ``big'', but this may be because
-the big parameter of the main tableau also appears
-in the context tableau.
-
-Finally, it was reported by \shortciteN{Galea2009personal}, who
-worked on a parametric integer programming implementation
-in {\tt PPL} \shortcite{PPL},
-that it is beneficial to add cuts for \emph{all} rational coordinates
-in the context tableau.  Based on this report,
-the initial {\tt isl} implementation was adapted accordingly.
-
-\subsubsection{Generalized Basis Reduction}\label{s:GBR}
-
-The default algorithm used in {\tt isl} for feasibility checking
-is generalized basis reduction \shortcite{Cook1991implementation}.
-This algorithm is also used in the {\tt barvinok} implementation.
-The algorithm is fairly robust, but it has some overhead.
-We therefore try to avoid calling the algorithm in easy cases.
-In particular, we incrementally keep track of points for which
-the entire unit hypercube positioned at that point lies in the context.
-This set is described by translates of the constraints of the context
-and if (rationally) non-empty, any rational point
-in the set can be rounded up to yield an integer point in the context.
-
-A restriction of the algorithm is that it only works on bounded sets.
-The affine hull of the recession cone therefore needs to be projected
-out first.  As soon as the algorithm is invoked, we then also
-incrementally keep track of this recession cone.  The reduced basis
-found by one call of the algorithm is also reused as initial basis
-for the next call.
-
-Some problems lead to the
-introduction of many integer divisions.  Within a given context,
-some of these integer divisions may be equal to each other, even
-if the expressions are not identical, or they may be equal to some
-affine combination of other variables.
-To detect such cases, we compute the affine hull of the context
-each time a new integer division is added.  The algorithm used
-for computing this affine hull is that of \shortciteN{Karr1976affine},
-while the points used in this algorithm are obtained by performing
-integer feasibility checks on that part of the context outside
-the current approximation of the affine hull.
-The list of witnesses is used to construct an initial approximation
-of the hull, while any extra points found during the construction
-of the hull is added to this list.
-Any equality found in this way that expresses an integer division
-as an \emph{integer} affine combination of other variables is
-propagated to the main tableau, where it is used to eliminate that
-integer division.

-\subsection{Experiments}
-
-\autoref{t:comparison} compares the execution times of {\tt isl}
-(with both types of context tableau)
-on some more difficult instances to those of other tools,
-run on an Intel Xeon W3520 @ 2.66GHz.
-Easier problems such as the
-test cases distributed with {\tt Pip\-Lib} can be solved so quickly
-that we would only be measuring overhead such as input/output and conversions
-and not the running time of the actual algorithm.
-We compare the following versions:
-{\tt piplib-1.4.0-5-g0132fd9},
-{\tt barvinok-0.32.1-73-gc5d7751},
-{\tt isl-0.05.1-82-g3a37260}
-and {\tt PPL} version 0.11.2.
-
-The first test case is the following dependence analysis problem
-originating from the Phideo project \shortcite{Verhaegh1995PhD}
-that was communicated to us by Bart Kienhuis:
-\begin{lstlisting}[flexiblecolumns=true,breaklines=true]{}
-lexmax { [j1,j2] -> [i1,i2,i3,i4,i5,i6,i7,i8,i9,i10] : 1 <= i1,j1 <= 8 and 1 <= i2,i3,i4,i5,i6,i7,i8,i9,i10 <= 2 and 1 <= j2 <= 128 and i1-1 = j1-1 and i2-1+2*i3-2+4*i4-4+8*i5-8+16*i6-16+32*i7-32+64*i8-64+128*i9-128+256*i10-256=3*j2-3+66 };
-\end{lstlisting}
-This problem was the main inspiration
-for some of the optimizations in \autoref{s:GBR}.
-The second group of test cases are projections used during counting.
-The first nine of these come from \shortciteN{Seghir2006minimizing}.
-The remaining two come from \shortciteN{Verdoolaege2005experiences} and
-were used to drive the first, Gomory cuts based, implementation
-in {\tt isl}.
-The third and final group of test cases are borrowed from
-\shortciteN{Bygde2010licentiate} and inspired the offline symmetry detection
-of \autoref{s:offline}.  Without symmetry detection, the running times
-are 11s and 5.9s.
-All running times of {\tt barvinok} and {\tt isl} include a conversion
-to disjunctive normal form.  Without this conversion, the final two
-cases can be solved in 0.07s and 0.21s.
-The {\tt PipLib} implementation has some fixed limits and will
-sometimes report the problem to be too complex (TC), while on some other
-problems it will run out of memory (OOM).
-The {\tt barvinok} implementation does not support problems
-with a non-trivial lineality space (line) nor maximization problems (max).
-The Gomory cuts based {\tt isl} implementation was terminated after 1000
-minutes on the first problem.  The gbr version introduces some
-overhead on some of the easier problems, but is overall the clear winner.

-\subsection{Online Symmetry Detection}\label{s:online}
-
-Manual experiments on small instances of the problems of
-\shortciteN{Bygde2010licentiate} and an analysis of the results
-by the approximate MPA method developed by \shortciteN{Bygde2010licentiate}
-have revealed that these problems contain many more symmetries
-than can be detected using the offline method of \autoref{s:offline}.
-In this section, we present an online detection mechanism that has
-not been implemented yet, but that has shown promising results
-in manual applications.
-
-Let us first consider what happens when we do not perform offline
-symmetry detection.  At some point, one of the
-$b_i(\vec p) + \sp {\vec a} {\vec x} \ge 0$ constraints,
-say the $j$th constraint, appears as a column
-variable, say $c_1$, while the other constraints are represented
-as rows of the form $b_i(\vec p) - b_j(\vec p) + c$.
-The context is then split according to the relative order of
-$b_j(\vec p)$ and one of the remaining $b_i(\vec p)$.
-The offline method avoids this split by replacing all $b_i(\vec p)$
-by a single newly introduced parameter that represents the minimum
-of these $b_i(\vec p)$.
-In the online method the split is similarly avoided by the introduction
-of a new parameter.  In particular, a new parameter is introduced
-that represents
-$\left| b_j(\vec p) - b_i(\vec p) \right|_+ =
-\max(b_j(\vec p) - b_i(\vec p), 0)$.
-
-In general, let $r = b(\vec p) + \sp {\vec a} {\vec c}$ be a row
-of the tableau such that the sign of $b(\vec p)$ is indeterminate
-and such that exactly one of the elements of $\vec a$ is a $1$,
-while all remaining elements are non-positive.
-That is, $r = b(\vec p) + c_j - f$ with $f = -\sum_{i\ne j} a_i c_i \ge 0$.
-We introduce a new parameter $t$ with
-context constraints $t \ge -b(\vec p)$ and $t \ge 0$ and replace
-the column variable $c_j$ by $c' + t$.  The row $r$ is now equal
-to $b(\vec p) + t + c' - f$.  The constant term of this row is always
-non-negative because any negative value of $b(\vec p)$ is compensated
-by $t \ge -b(\vec p)$ while and non-negative value remains non-negative
-because $t \ge 0$.
-
-We need to show that this transformation does not eliminate any valid
-solutions and that it does not introduce any spurious solutions.
-Given a valid solution for the original problem, we need to find
-a non-negative value of $c'$ satisfying the constraints.
-If $b(\vec p) \ge 0$, we can take $t = 0$ so that
-$c' = c_j - t = c_j \ge 0$.
-If $b(\vec p) < 0$, we can take $t = -b(\vec p)$.
-Since $r = b(\vec p) + c_j - f \ge 0$ and $f \ge 0$, we have 
-$c' = c_j + b(\vec p) \ge 0$.
-Note that these choices amount to plugging in
-$t = \left|-b(\vec p)\right|_+ = \max(-b(\vec p), 0)$.
-Conversely, given a solution to the new problem, we need to find
-a non-negative value of $c_j$, but this is easy since $c_j = c' + t$
-and both of these are non-negative.
-
-Plugging in $t = \max(-b(\vec p), 0)$ can be performed as in
-\autoref{s:post}, but, as in the case of offline symmetry detection,
-it may be better to provide a direct representation for such
-expressions in the internal representation of sets and relations
-or at least in a quast-like output format.

-\section{Transitive Closure}
-
-\subsection{Introduction}
-
-\begin{definition}[Power of a Relation]
-Let $R \in \Z^n \to 2^{\Z^{d+d}}$ be a relation and
-$k \in \Z_{\ge 1}$
-a positive number, then power $k$ of relation $R$ is defined as
-\begin{equation}
-\label{eq:transitive:power}
-R^k \coloneqq
-\begin{cases}
-R & \text{if $k = 1$}
-\\
-R \circ R^{k-1} & \text{if $k \ge 2$}
-.
-\end{cases}
-\end{equation}
-\end{definition}
-
-\begin{definition}[Transitive Closure of a Relation]
-Let $R \in \Z^n \to 2^{\Z^{d+d}}$ be a relation,
-then the transitive closure $R^+$ of $R$ is the union
-of all positive powers of $R$,
-$$
-R^+ \coloneqq \bigcup_{k \ge 1} R^k
-.
-$$
-\end{definition}
-Alternatively, the transitive closure may be defined
-inductively as
-\begin{equation}
-\label{eq:transitive:inductive}
-R^+ \coloneqq R \cup \left(R \circ R^+\right)
-.
-\end{equation}
-
-Since the transitive closure of a polyhedral relation
-may no longer be a polyhedral relation \shortcite{Kelly1996closure},
-we can, in the general case, only compute an approximation
-of the transitive closure.
-Whereas \shortciteN{Kelly1996closure} compute underapproximations,
-we, like \shortciteN{Beletska2009}, compute overapproximations.
-That is, given a relation $R$, we will compute a relation $T$
-such that $R^+ \subseteq T$.  Of course, we want this approximation
-to be as close as possible to the actual transitive closure
-$R^+$ and we want to detect the cases where the approximation is
-exact, i.e., where $T = R^+$.
-
-For computing an approximation of the transitive closure of $R$,
-we follow the same general strategy as \shortciteN{Beletska2009}
-and first compute an approximation of $R^k$ for $k \ge 1$ and then project
-out the parameter $k$ from the resulting relation.
-
-\begin{example}
-As a trivial example, consider the relation
-$R = \{\, x \to x + 1 \,\}$.  The $k$th power of this map
-for arbitrary $k$ is
-$$
-R^k = k \mapsto \{\, x \to x + k \mid k \ge 1 \,\}
-.
-$$
-The transitive closure is then
-$$
-\begin{aligned}
-R^+ & = \{\, x \to y \mid \exists k \in \Z_{\ge 1} : y = x + k \,\}
-\\
-& = \{\, x \to y \mid y \ge x + 1 \,\}
-.
-\end{aligned}
-$$
-\end{example}
-
-\subsection{Computing an Approximation of $R^k$}
-\label{s:power}
-
-There are some special cases where the computation of $R^k$ is very easy.
-One such case is that where $R$ does not compose with itself,
-i.e., $R \circ R = \emptyset$ or $\domain R \cap \range R = \emptyset$.
-In this case, $R^k$ is only non-empty for $k=1$ where it is equal
-to $R$ itself.
-
-In general, it is impossible to construct a closed form
-of $R^k$ as a polyhedral relation.
-We will therefore need to make some approximations.
-As a first approximations, we will consider each of the basic
-relations in $R$ as simply adding one or more offsets to a domain element
-to arrive at an image element and ignore the fact that some of these
-offsets may only be applied to some of the domain elements.
-That is, we will only consider the difference set $\Delta\,R$ of the relation.
-In particular, we will first construct a collection $P$ of paths
-that move through
-a total of $k$ offsets and then intersect domain and range of this
-collection with those of $R$.
-That is, 
-\begin{equation}
-\label{eq:transitive:approx}
-K = P \cap \left(\domain R \to \range R\right)
-,
-\end{equation}
-with
-\begin{equation}
-\label{eq:transitive:path}
-P = \vec s \mapsto \{\, \vec x \to \vec y \mid
-\exists k_i \in \Z_{\ge 0}, \vec\delta_i \in k_i \, \Delta_i(\vec s) :
-\vec y = \vec x + \sum_i \vec\delta_i
-\wedge
-\sum_i k_i = k > 0
-\,\}
-\end{equation}
-and with $\Delta_i$ the basic sets that compose
-the difference set $\Delta\,R$.
-Note that the number of basic sets $\Delta_i$ need not be
-the same as the number of basic relations in $R$.
-Also note that since addition is commutative, it does not
-matter in which order we add the offsets and so we are allowed
-to group them as we did in \eqref{eq:transitive:path}.
-
-If all the $\Delta_i$s are singleton sets
-$\Delta_i = \{\, \vec \delta_i \,\}$ with $\vec \delta_i \in \Z^d$,
-then \eqref{eq:transitive:path} simplifies to
-\begin{equation}
-\label{eq:transitive:singleton}
-P = \{\, \vec x \to \vec y \mid
-\exists k_i \in \Z_{\ge 0} :
-\vec y = \vec x + \sum_i k_i \, \vec \delta_i
-\wedge
-\sum_i k_i = k > 0
-\,\}
-\end{equation}
-and then the approximation computed in \eqref{eq:transitive:approx}
-is essentially the same as that of \shortciteN{Beletska2009}.
-If some of the $\Delta_i$s are not singleton sets or if
-some of $\vec \delta_i$s are parametric, then we need
-to resort to further approximations.
-
-To ease both the exposition and the implementation, we will for
-the remainder of this section work with extended offsets
-$\Delta_i' = \Delta_i \times \{\, 1 \,\}$.
-That is, each offset is extended with an extra coordinate that is
-set equal to one.  The paths constructed by summing such extended
-offsets have the length encoded as the difference of their
-final coordinates.  The path $P'$ can then be decomposed into
-paths $P_i'$, one for each $\Delta_i$,
-\begin{equation}
-\label{eq:transitive:decompose}
-P' = \left(
-(P_m' \cup \identity) \circ \cdots \circ
-(P_2' \cup \identity) \circ
-(P_1' \cup \identity)
-\right) \cap
-\{\,
-\vec x' \to \vec y' \mid y_{d+1} - x_{d+1} = k > 0
-\,\}
-,
-\end{equation}
-with
-$$
-P_i' = \vec s \mapsto \{\, \vec x' \to \vec y' \mid
-\exists k \in \Z_{\ge 1}, \vec \delta \in k \, \Delta_i'(\vec s) :
-\vec y' = \vec x' + \vec \delta
-\,\}
-.
-$$
-Note that each $P_i'$ contains paths of length at least one.
-We therefore need to take the union with the identity relation
-when composing the $P_i'$s to allow for paths that do not contain
-any offsets from one or more $\Delta_i'$.
-The path that consists of only identity relations is removed
-by imposing the constraint $y_{d+1} - x_{d+1} > 0$.
-Taking the union with the identity relation means that
-that the relations we compose in \eqref{eq:transitive:decompose}
-each consist of two basic relations.  If there are $m$
-disjuncts in the input relation, then a direct application
-of the composition operation may therefore result in a relation
-with $2^m$ disjuncts, which is prohibitively expensive.
-It is therefore crucial to apply coalescing (\autoref{s:coalescing})
-after each composition.
-
-Let us now consider how to compute an overapproximation of $P_i'$.
-Those that correspond to singleton $\Delta_i$s are grouped together
-and handled as in \eqref{eq:transitive:singleton}.
-Note that this is just an optimization.  The procedure described
-below would produce results that are at least as accurate.
-For simplicity, we first assume that no constraint in $\Delta_i'$
-involves any existentially quantified variables.
-We will return to existentially quantified variables at the end
-of this section.
-Without existentially quantified variables, we can classify
-the constraints of $\Delta_i'$ as follows
-\begin{enumerate}
-\item non-parametric constraints
-\begin{equation}
-\label{eq:transitive:non-parametric}
-A_1 \vec x + \vec c_1 \geq \vec 0
-\end{equation}
-\item purely parametric constraints
-\begin{equation}
-\label{eq:transitive:parametric}
-B_2 \vec s + \vec c_2 \geq \vec 0
-\end{equation}
-\item negative mixed constraints
-\begin{equation}
-\label{eq:transitive:mixed}
-A_3 \vec x + B_3 \vec s + \vec c_3 \geq \vec 0
-\end{equation}
-such that for each row $j$ and for all $\vec s$,
-$$
-\Delta_i'(\vec s) \cap
-\{\, \vec \delta' \mid B_{3,j} \vec s + c_{3,j} > 0 \,\}
-= \emptyset
-$$
-\item positive mixed constraints
-$$
-A_4 \vec x + B_4 \vec s + \vec c_4 \geq \vec 0
-$$
-such that for each row $j$, there is at least one $\vec s$ such that
-$$
-\Delta_i'(\vec s) \cap
-\{\, \vec \delta' \mid B_{4,j} \vec s + c_{4,j} > 0 \,\}
-\ne \emptyset
-$$
-\end{enumerate}
-We will use the following approximation $Q_i$ for $P_i'$:
-\begin{equation}
-\label{eq:transitive:Q}
-\begin{aligned}
-Q_i = \vec s \mapsto
-\{\,
-\vec x' \to \vec y'
-\mid {} & \exists k \in \Z_{\ge 1}, \vec f \in \Z^d :
-\vec y' = \vec x' + (\vec f, k)
-\wedge {}
-\\
-&
-A_1 \vec f + k \vec c_1 \geq \vec 0
-\wedge
-B_2 \vec s + \vec c_2 \geq \vec 0
-\wedge
-A_3 \vec f + B_3 \vec s + \vec c_3 \geq \vec 0
-\,\}
-.
-\end{aligned}
-\end{equation}
-To prove that $Q_i$ is indeed an overapproximation of $P_i'$,
-we need to show that for every $\vec s \in \Z^n$, for every
-$k \in \Z_{\ge 1}$ and for every $\vec f \in k \, \Delta_i(\vec s)$
-we have that
-$(\vec f, k)$ satisfies the constraints in \eqref{eq:transitive:Q}.
-If $\Delta_i(\vec s)$ is non-empty, then $\vec s$ must satisfy
-the constraints in \eqref{eq:transitive:parametric}.
-Each element $(\vec f, k) \in k \, \Delta_i'(\vec s)$ is a sum
-of $k$ elements $(\vec f_j, 1)$ in $\Delta_i'(\vec s)$.
-Each of these elements satisfies the constraints in
-\eqref{eq:transitive:non-parametric}, i.e.,
-$$
-\left[
-\begin{matrix}
-A_1 & \vec c_1
-\end{matrix}
-\right]
-\left[
-\begin{matrix}
-\vec f_j \\ 1
-\end{matrix}
-\right]
-\ge \vec 0
-.
-$$
-The sum of these elements therefore satisfies the same set of inequalities,
-i.e., $A_1 \vec f + k \vec c_1 \geq \vec 0$.
-Finally, the constraints in \eqref{eq:transitive:mixed} are such
-that for any $\vec s$ in the parameter domain of $\Delta$,
-we have $-\vec r(\vec s) \coloneqq B_3 \vec s + \vec c_3 \le \vec 0$,
-i.e., $A_3 \vec f_j \ge \vec r(\vec s) \ge \vec 0$
-and therefore also $A_3 \vec f \ge \vec r(\vec s)$.
-Note that if there are no mixed constraints and if the
-rational relaxation of $\Delta_i(\vec s)$, i.e.,
-$\{\, \vec x \in \Q^d \mid A_1 \vec x + \vec c_1 \ge \vec 0\,\}$,
-has integer vertices, then the approximation is exact, i.e.,
-$Q_i = P_i'$.  In this case, the vertices of $\Delta'_i(\vec s)$
-generate the rational cone
-$\{\, \vec x' \in \Q^{d+1} \mid \left[
-\begin{matrix}
-A_1 & \vec c_1
-\end{matrix}
-\right] \vec x' \,\}$ and therefore $\Delta'_i(\vec s)$ is
-a Hilbert basis of this cone \shortcite[Theorem~16.4]{Schrijver1986}.
-
-Note however that, as pointed out by \shortciteN{DeSmet2010personal},
-if there \emph{are} any mixed constraints, then the above procedure may
-not compute the most accurate affine approximation of
-$k \, \Delta_i(\vec s)$ with $k \ge 1$.
-In particular, we only consider the negative mixed constraints that
-happen to appear in the description of $\Delta_i(\vec s)$, while we
-should instead consider \emph{all} valid such constraints.
-It is also sufficient to consider those constraints because any
-constraint that is valid for $k \, \Delta_i(\vec s)$ is also
-valid for $1 \, \Delta_i(\vec s) = \Delta_i(\vec s)$.
-Take therefore any constraint
-$\spv a x + \spv b s + c \ge 0$ valid for $\Delta_i(\vec s)$.
-This constraint is also valid for $k \, \Delta_i(\vec s)$ iff
-$k \, \spv a x + \spv b s + c \ge 0$.
-If $\spv b s + c$ can attain any positive value, then $\spv a x$
-may be negative for some elements of $\Delta_i(\vec s)$.
-We then have $k \, \spv a x < \spv a x$ for $k > 1$ and so the constraint
-is not valid for $k \, \Delta_i(\vec s)$.
-We therefore need to impose $\spv b s + c \le 0$ for all values
-of $\vec s$ such that $\Delta_i(\vec s)$ is non-empty, i.e.,
-$\vec b$ and $c$ need to be such that $- \spv b s - c \ge 0$ is a valid
-constraint of $\Delta_i(\vec s)$.  That is, $(\vec b, c)$ are the opposites
-of the coefficients of a valid constraint of $\Delta_i(\vec s)$.
-The approximation of $k \, \Delta_i(\vec s)$ can therefore be obtained
-using three applications of Farkas' lemma.  The first obtains the coefficients
-of constraints valid for $\Delta_i(\vec s)$.  The second obtains
-the coefficients of constraints valid for the projection of $\Delta_i(\vec s)$
-onto the parameters.  The opposite of the second set is then computed
-and intersected with the first set.  The result is the set of coefficients
-of constraints valid for $k \, \Delta_i(\vec s)$.  A final application
-of Farkas' lemma is needed to obtain the approximation of
-$k \, \Delta_i(\vec s)$ itself.
-
-\begin{example}
-Consider the relation
-$$
-n \to \{\, (x, y) \to (1 + x, 1 - n + y) \mid n \ge 2 \,\}
-.
-$$
-The difference set of this relation is
-$$
-\Delta = n \to \{\, (1, 1 - n) \mid n \ge 2 \,\}
-.
-$$
-Using our approach, we would only consider the mixed constraint
-$y - 1 + n \ge 0$, leading to the following approximation of the
-transitive closure:
-$$
-n \to \{\, (x, y) \to (o_0, o_1) \mid n \ge 2 \wedge o_1 \le 1 - n + y \wedge o_0 \ge 1 + x \,\}
-.
-$$
-If, instead, we apply Farkas's lemma to $\Delta$, i.e.,
-\begin{verbatim}
-D := [n] -> { [1, 1 - n] : n >= 2 };
-CD := coefficients D;
-CD;
-\end{verbatim}
-we obtain
-\begin{verbatim}
-{ rat: coefficients[[c_cst, c_n] -> [i2, i3]] : i3 <= c_n and
-  i3 <= c_cst + 2c_n + i2 }
-\end{verbatim}
-The pure-parametric constraints valid for $\Delta$,
-\begin{verbatim}
-P := { [a,b] -> [] }(D);
-CP := coefficients P;
-CP;
-\end{verbatim}
-are
-\begin{verbatim}
-{ rat: coefficients[[c_cst, c_n] -> []] : c_n >= 0 and 2c_n >= -c_cst }
-\end{verbatim}
-Negating these coefficients and intersecting with \verb+CD+,
-\begin{verbatim}
-NCP := { rat: coefficients[[a,b] -> []]
-              -> coefficients[[-a,-b] -> []] }(CP);
-CK := wrap((unwrap CD) * (dom (unwrap NCP)));
-CK;
-\end{verbatim}
-we obtain
-\begin{verbatim}
-{ rat: [[c_cst, c_n] -> [i2, i3]] : i3 <= c_n and
-  i3 <= c_cst + 2c_n + i2 and c_n <= 0 and 2c_n <= -c_cst }
-\end{verbatim}
-The approximation for $k\,\Delta$,
-\begin{verbatim}
-K := solutions CK;
-K;
-\end{verbatim}
-is then
-\begin{verbatim}
-[n] -> { rat: [i0, i1] : i1 <= -i0 and i0 >= 1 and i1 <= 2 - n - i0 }
-\end{verbatim}
-Finally, the computed approximation for $R^+$,
-\begin{verbatim}
-T := unwrap({ [dx,dy] -> [[x,y] -> [x+dx,y+dy]] }(K));
-R := [n] -> { [x,y] -> [x+1,y+1-n] : n >= 2 };
-T := T * ((dom R) -> (ran R));
-T;
-\end{verbatim}
-is
-\begin{verbatim}
-[n] -> { [x, y] -> [o0, o1] : o1 <= x + y - o0 and
-         o0 >= 1 + x and o1 <= 2 - n + x + y - o0 and n >= 2 }
-\end{verbatim}
-\end{example}
-
-Existentially quantified variables can be handled by
-classifying them into variables that are uniquely
-determined by the parameters, variables that are independent
-of the parameters and others.  The first set can be treated
-as parameters and the second as variables.  Constraints involving
-the other existentially quantified variables are removed.
-
-\begin{example}
-Consider the relation
-$$
-R =
-n \to \{\, x \to y \mid \exists \, \alpha_0, \alpha_1: 7\alpha_0 = -2 + n \wedge 5\alpha_1 = -1 - x + y \wedge y \ge 6 + x \,\}
-.
-$$
-The difference set of this relation is
-$$
-\Delta = \Delta \, R =
-n \to \{\, x \mid \exists \, \alpha_0, \alpha_1: 7\alpha_0 = -2 + n \wedge 5\alpha_1 = -1 + x \wedge x \ge 6 \,\}
-.
-$$
-The existentially quantified variables can be defined in terms
-of the parameters and variables as
-$$
-\alpha_0 = \floor{\frac{-2 + n}7}
-\qquad
-\text{and}
-\qquad
-\alpha_1 = \floor{\frac{-1 + x}5}
-.
-$$
-$\alpha_0$ can therefore be treated as a parameter,
-while $\alpha_1$ can be treated as a variable.
-This in turn means that $7\alpha_0 = -2 + n$ can be treated as
-a purely parametric constraint, while the other two constraints are
-non-parametric.
-The corresponding $Q$~\eqref{eq:transitive:Q} is therefore
-$$
-\begin{aligned}
-n \to \{\, (x,z) \to (y,w) \mid
-\exists\, \alpha_0, \alpha_1, k, f : {} &
-k \ge 1 \wedge
-y = x + f \wedge
-w = z + k \wedge {} \\
-&
-7\alpha_0 = -2 + n \wedge
-5\alpha_1 = -k + x \wedge
-x \ge 6 k
-\,\}
-.
-\end{aligned}
-$$
-Projecting out the final coordinates encoding the length of the paths,
-results in the exact transitive closure
-$$
-R^+ =
-n \to \{\, x \to y \mid \exists \, \alpha_0, \alpha_1: 7\alpha_1 = -2 + n \wedge 6\alpha_0 \ge -x + y \wedge 5\alpha_0 \le -1 - x + y \,\}
-.
-$$
-\end{example}
-
-The fact that we ignore some impure constraints clearly leads
-to a loss of accuracy.  In some cases, some of this loss can be recovered
-by not considering the parameters in a special way.
-That is, instead of considering the set
-$$
-\Delta = \diff R =
-\vec s \mapsto
-\{\, \vec \delta \in \Z^{d} \mid \exists \vec x \to \vec y \in R :
-\vec \delta = \vec y - \vec x
-\,\}
-$$
-we consider the set
-$$
-\Delta' = \diff R' =
-\{\, \vec \delta \in \Z^{n+d} \mid \exists
-(\vec s, \vec x) \to (\vec s, \vec y) \in R' :
-\vec \delta = (\vec s - \vec s, \vec y - \vec x)
-\,\}
-.
-$$
-The first $n$ coordinates of every element in $\Delta'$ are zero.
-Projecting out these zero coordinates from $\Delta'$ is equivalent
-to projecting out the parameters in $\Delta$.
-The result is obviously a superset of $\Delta$, but all its constraints
-are of type \eqref{eq:transitive:non-parametric} and they can therefore
-all be used in the construction of $Q_i$.
-
-\begin{example}
-Consider the relation
-$$
-% [n] -> { [x, y] -> [1 + x, 1 - n + y] | n >= 2 }
-R = n \to \{\, (x, y) \to (1 + x, 1 - n + y) \mid n \ge 2 \,\}
-.
-$$
-We have
-$$
-\diff R = n \to \{\, (1, 1 - n) \mid n \ge 2 \,\}
-$$
-and so, by treating the parameters in a special way, we obtain
-the following approximation for $R^+$:
-$$
-n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge y' \le 1 - n + y \wedge x' \ge 1 + x \,\}
-.
-$$
-If we consider instead
-$$
-R' = \{\, (n, x, y) \to (n, 1 + x, 1 - n + y) \mid n \ge 2 \,\}
-$$
-then
-$$
-\diff R' = \{\, (0, 1, y) \mid y \le -1 \,\}
-$$
-and we obtain the approximation
-$$
-n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge x' \ge 1 + x \wedge y' \le x + y - x' \,\}
-.
-$$
-If we consider both $\diff R$ and $\diff R'$, then we obtain
-$$
-n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge y' \le 1 - n + y \wedge x' \ge 1 + x \wedge y' \le x + y - x' \,\}
-.
-$$
-Note, however, that this is not the most accurate affine approximation that
-can be obtained.  That would be
-$$
-n \to \{\, (x, y) \to (x', y') \mid y' \le 2 - n + x + y - x' \wedge n \ge 2 \wedge x' \ge 1 + x \,\}
-.
-$$
-\end{example}

-\subsection{Checking Exactness}
-
-The approximation $T$ for the transitive closure $R^+$ can be obtained
-by projecting out the parameter $k$ from the approximation $K$
-\eqref{eq:transitive:approx} of the power $R^k$.
-Since $K$ is an overapproximation of $R^k$, $T$ will also be an
-overapproximation of $R^+$.
-To check whether the results are exact, we need to consider two
-cases depending on whether $R$ is {\em cyclic}, where $R$ is defined
-to be cyclic if $R^+$ maps any element to itself, i.e.,
-$R^+ \cap \identity \ne \emptyset$.
-If $R$ is acyclic, then the inductive definition of
-\eqref{eq:transitive:inductive} is equivalent to its completion,
-i.e.,
-$$
-R^+ = R \cup \left(R \circ R^+\right)
-$$
-is a defining property.
-Since $T$ is known to be an overapproximation, we only need to check
-whether
-$$
-T \subseteq R \cup \left(R \circ T\right)
-.
-$$
-This is essentially Theorem~5 of \shortciteN{Kelly1996closure}.
-The only difference is that they only consider lexicographically
-forward relations, a special case of acyclic relations.
-
-If, on the other hand, $R$ is cyclic, then we have to resort
-to checking whether the approximation $K$ of the power is exact.
-Note that $T$ may be exact even if $K$ is not exact, so the check
-is sound, but incomplete.
-To check exactness of the power, we simply need to check
-\eqref{eq:transitive:power}.  Since again $K$ is known
-to be an overapproximation, we only need to check whether
-$$
-\begin{aligned}
-K'|_{y_{d+1} - x_{d+1} = 1} & \subseteq R'
-\\
-K'|_{y_{d+1} - x_{d+1} \ge 2} & \subseteq R' \circ K'|_{y_{d+1} - x_{d+1} \ge 1}
-,
-\end{aligned}
-$$
-where $R' = \{\, \vec x' \to \vec y' \mid \vec x \to \vec y \in R
-\wedge y_{d+1} - x_{d+1} = 1\,\}$, i.e., $R$ extended with path
-lengths equal to 1.
-
-All that remains is to explain how to check the cyclicity of $R$.
-Note that the exactness on the power is always sound, even
-in the acyclic case, so we only need to be careful that we find
-all cyclic cases.  Now, if $R$ is cyclic, i.e.,
-$R^+ \cap \identity \ne \emptyset$, then, since $T$ is
-an overapproximation of $R^+$, also
-$T \cap \identity \ne \emptyset$.  This in turn means
-that $\Delta \, K'$ contains a point whose first $d$ coordinates
-are zero and whose final coordinate is positive.
-In the implementation we currently perform this test on $P'$ instead of $K'$.
-Note that if $R^+$ is acyclic and $T$ is not, then the approximation
-is clearly not exact and the approximation of the power $K$
-will not be exact either.
-
-\subsection{Decomposing $R$ into strongly connected components}
-
-If the input relation $R$ is a union of several basic relations
-that can be partially ordered
-then the accuracy of the approximation may be improved by computing
-an approximation of each strongly connected components separately.
-For example, if $R = R_1 \cup R_2$ and $R_1 \circ R_2 = \emptyset$,
-then we know that any path that passes through $R_2$ cannot later
-pass through $R_1$, i.e.,
-\begin{equation}
-\label{eq:transitive:components}
-R^+ = R_1^+ \cup R_2^+ \cup \left(R_2^+ \circ R_1^+\right)
-.
-\end{equation}
-We can therefore compute (approximations of) transitive closures
-of $R_1$ and $R_2$ separately.
-Note, however, that the condition $R_1 \circ R_2 = \emptyset$
-is actually too strong.
-If $R_1 \circ R_2$ is a subset of $R_2 \circ R_1$
-then we can reorder the segments
-in any path that moves through both $R_1$ and $R_2$ to
-first move through $R_1$ and then through $R_2$.
-
-This idea can be generalized to relations that are unions
-of more than two basic relations by constructing the
-strongly connected components in the graph with as vertices
-the basic relations and an edge between two basic relations
-$R_i$ and $R_j$ if $R_i$ needs to follow $R_j$ in some paths.
-That is, there is an edge from $R_i$ to $R_j$ iff
-\begin{equation}
-\label{eq:transitive:edge}
-R_i \circ R_j
-\not\subseteq
-R_j \circ R_i
-.
-\end{equation}
-The components can be obtained from the graph by applying
-Tarjan's algorithm \shortcite{Tarjan1972}.
-
-In practice, we compute the (extended) powers $K_i'$ of each component
-separately and then compose them as in \eqref{eq:transitive:decompose}.
-Note, however, that in this case the order in which we apply them is
-important and should correspond to a topological ordering of the
-strongly connected components.  Simply applying Tarjan's
-algorithm will produce topologically sorted strongly connected components.
-The graph on which Tarjan's algorithm is applied is constructed on-the-fly.
-That is, whenever the algorithm checks if there is an edge between
-two vertices, we evaluate \eqref{eq:transitive:edge}.
-The exactness check is performed on each component separately.
-If the approximation turns out to be inexact for any of the components,
-then the entire result is marked inexact and the exactness check
-is skipped on the components that still need to be handled.
-
-It should be noted that \eqref{eq:transitive:components}
-is only valid for exact transitive closures.
-If overapproximations are computed in the right hand side, then the result will
-still be an overapproximation of the left hand side, but this result
-may not be transitively closed.  If we only separate components based
-on the condition $R_i \circ R_j = \emptyset$, then there is no problem,
-as this condition will still hold on the computed approximations
-of the transitive closures.  If, however, we have exploited
-\eqref{eq:transitive:edge} during the decomposition and if the
-result turns out not to be exact, then we check whether
-the result is transitively closed.  If not, we recompute
-the transitive closure, skipping the decomposition.
-Note that testing for transitive closedness on the result may
-be fairly expensive, so we may want to make this check
-configurable.

-.

-$$
-The figure shows this relation for $n = 7$.
-Both
-$R_3 \circ R_1 \subseteq R_1 \circ R_3$
-and
-$R_3 \circ R_2 \subseteq R_2 \circ R_3$,
-which the reader can verify using the {\tt iscc} calculator:
-\begin{verbatim}
-R1 := [n] -> { [i,j] -> [i+3,j] : i <= 2 j - 4 and i <= n - 3 and
-                                  j <= 2 i - 1 and j <= n };
-R2 := [n] -> { [i,j] -> [i,j+3] : i <= 2 j - 1 and i <= n and

-(R1 . R3) - (R3 . R1);
-(R2 . R3) - (R3 . R2);

-$R_3$ can therefore be moved forward in any path.
-For the other two basic relations, we have both
-$R_2 \circ R_1 \not\subseteq R_1 \circ R_2$
-and
-$R_1 \circ R_2 \not\subseteq R_2 \circ R_1$
-and so $R_1$ and $R_2$ form a strongly connected component.
-By computing the power of $R_3$ and $R_1 \cup R_2$ separately
-and composing the results, the power of $R$ can be computed exactly
-using \eqref{eq:transitive:singleton}.
-As explained by \shortciteN{Beletska2009}, applying the same formula
-to $R$ directly, without a decomposition, would result in
-an overapproximation of the power.
-\end{example}
-
-\subsection{Partitioning the domains and ranges of $R$}
-
-The algorithm of \autoref{s:power} assumes that the input relation $R$
-can be treated as a union of translations.
-This is a reasonable assumption if $R$ maps elements of a given
-abstract domain to the same domain.
-However, if $R$ is a union of relations that map between different
-domains, then this assumption no longer holds.
-In particular, when an entire dependence graph is encoded
-in a single relation, as is done by, e.g.,
-\shortciteN[Section~6.1]{Barthou2000MSE}, then it does not make
-sense to look at differences between iterations of different domains.
-Now, arguably, a modified Floyd-Warshall algorithm should
-be applied to the dependence graph, as advocated by
-\shortciteN{Kelly1996closure}, with the transitive closure operation
-only being applied to relations from a given domain to itself.
-However, it is also possible to detect disjoint domains and ranges
-and to apply Floyd-Warshall internally.

-Let the input relation $R$ be a union of $m$ basic relations $R_i$.
-Let $D_{2i}$ be the domains of $R_i$ and $D_{2i+1}$ the ranges of $R_i$.

-then we continue with the algorithm of \autoref{s:power}.
-Otherwise, we apply Floyd-Warshall on the graph with as vertices

-the appropriate pairs of vertices.
-In particular, let there be $n$ parts $P_k$ in the partition.
-We construct $n^2$ relations

-apply \autoref{a:Floyd} and return the union of all resulting

-Each iteration of the $r$-loop in \autoref{a:Floyd} updates
-all relations $R_{pq}$ to include paths that go from $p$ to $r$,
-possibly stay there for a while, and then go from $r$ to $q$.
-Note that paths that ``stay in $r$'' include all paths that
-pass through earlier vertices since $R_{rr}$ itself has been updated
-accordingly in previous iterations of the outer loop.
-In principle, it would be sufficient to use the $R_{pr}$
-and $R_{rq}$ computed in the previous iteration of the
-$r$-loop in Line~\ref{l:Floyd:update}.
-However, from an implementation perspective, it is easier
-to allow either or both of these to have been updated
-in the same iteration of the $r$-loop.
-This may result in duplicate paths, but these can usually
-be removed by coalescing (\autoref{s:coalescing}) the result of the union
-in Line~\ref{l:Floyd:update}, which should be done in any case.
-The transitive closure in Line~\ref{l:Floyd:closure}
-is performed using a recursive call.  This recursive call
-includes the partitioning step, but the resulting partition will
-usually be a singleton.
-The result of the recursive call will either be exact or an
-overapproximation.  The final result of Floyd-Warshall is therefore
-also exact or an overapproximation.

-\caption{The relation (solid arrows) on the right of Figure~1 of
-\protect\shortciteN{Beletska2009} and its transitive closure}
-\label{f:COCOA:1}
-\end{figure}
-\begin{example}
-Consider the relation on the right of Figure~1 of
-\shortciteN{Beletska2009},
-reproduced in \autoref{f:COCOA:1}.
-This relation can be described as
-$$
-\begin{aligned}
-\{\, (x, y) \to (x_2, y_2) \mid {} & (3y = 2x \wedge x_2 = x \wedge 3y_2 = 3 + 2x \wedge x \ge 0 \wedge x \le 3) \vee {} \\
-& (x_2 = 1 + x \wedge y_2 = y \wedge x \ge 0 \wedge 3y \ge 2 + 2x \wedge x \le 2 \wedge 3y \le 3 + 2x) \,\}
-.
-\end{aligned}
-$$
-Note that the domain of the upward relation overlaps with the range
-of the rightward relation and vice versa, but that the domain
-of neither relation overlaps with its own range or the domain of
-the other relation.
-The domains and ranges can therefore be partitioned into two parts,
-$P_0$ and $P_1$, shown as the white and black dots in \autoref{f:COCOA:1},
-respectively.
-Initially, we have
-$$
-\begin{aligned}
-R_{00} & = \emptyset
-\\
-R_{01} & = 
-\{\, (x, y) \to (x+1, y) \mid 
-(x \ge 0 \wedge 3y \ge 2 + 2x \wedge x \le 2 \wedge 3y \le 3 + 2x) \,\}
-\\
-R_{10} & =
-\{\, (x, y) \to (x_2, y_2) \mid (3y = 2x \wedge x_2 = x \wedge 3y_2 = 3 + 2x \wedge x \ge 0 \wedge x \le 3) \,\}
-\\
-R_{11} & = \emptyset
-.
-\end{aligned}
-$$
-In the first iteration, $R_{00}$ remains the same ($\emptyset^+ = \emptyset$).
-$R_{01}$ and $R_{10}$ are therefore also unaffected, but
-$R_{11}$ is updated to include $R_{01} \circ R_{10}$, i.e.,
-the dashed arrow in the figure.
-This new $R_{11}$ is obviously transitively closed, so it is not
-changed in the second iteration and it does not have an effect
-on $R_{01}$ and $R_{10}$.  However, $R_{00}$ is updated to
-include $R_{10} \circ R_{01}$, i.e., the dotted arrow in the figure.
-The transitive closure of the original relation is then equal to
-$R_{00} \cup R_{01} \cup R_{10} \cup R_{11}$.
-\end{example}
-
-\subsection{Incremental Computation}
-\label{s:incremental}
-
-In some cases it is possible and useful to compute the transitive closure
-of union of basic relations incrementally.  In particular,
-if $R$ is a union of $m$ basic maps,
-$$
-R = \bigcup_j R_j
-,
-$$
-then we can pick some $R_i$ and compute the transitive closure of $R$ as
-\begin{equation}
-\label{eq:transitive:incremental}
-R^+ = R_i^+ \cup
-\left(
-\bigcup_{j \ne i}
-R_i^* \circ R_j \circ R_i^*
-\right)^+
-.
-\end{equation}
-For this approach to be successful, it is crucial that each
-of the disjuncts in the argument of the second transitive
-closure in \eqref{eq:transitive:incremental} be representable
-as a single basic relation, i.e., without a union.
-If this condition holds, then by using \eqref{eq:transitive:incremental},
-the number of disjuncts in the argument of the transitive closure
-can be reduced by one.
-Now, $R_i^* = R_i^+ \cup \identity$, but in some cases it is possible
-to relax the constraints of $R_i^+$ to include part of the identity relation,
-say on domain $D$.  We will use the notation
-${\cal C}(R_i,D) = R_i^+ \cup \identity_D$ to represent
-this relaxed version of $R^+$.
-\shortciteN{Kelly1996closure} use the notation $R_i^?$.
-${\cal C}(R_i,D)$ can be computed by allowing $k$ to attain
-the value $0$ in \eqref{eq:transitive:Q} and by using
-$$
-P \cap \left(D \to D\right)
-$$
-instead of \eqref{eq:transitive:approx}.
-Typically, $D$ will be a strict superset of both $\domain R_i$
-and $\range R_i$.  We therefore need to check that domain
-and range of the transitive closure are part of ${\cal C}(R_i,D)$,
-i.e., the part that results from the paths of positive length ($k \ge 1$),
-are equal to the domain and range of $R_i$.
-If not, then the incremental approach cannot be applied for
-the given choice of $R_i$ and $D$.
-
-In order to be able to replace $R^*$ by ${\cal C}(R_i,D)$
-in \eqref{eq:transitive:incremental}, $D$ should be chosen
-to include both $\domain R$ and $\range R$, i.e., such
-that $\identity_D \circ R_j \circ \identity_D = R_j$ for all $j\ne i$.
-\shortciteN{Kelly1996closure} say that they use
-$D = \domain R_i \cup \range R_i$, but presumably they mean that
-they use $D = \domain R \cup \range R$.
-Now, this expression of $D$ contains a union, so it not directly usable.
-\shortciteN{Kelly1996closure} do not explain how they avoid this union.
-Apparently, in their implementation,
-they are using the convex hull of $\domain R \cup \range R$
-or at least an approximation of this convex hull.
-We use the simple hull (\autoref{s:simple hull}) of $\domain R \cup \range R$.
-
-It is also possible to use a domain $D$ that does {\em not\/}
-include $\domain R \cup \range R$, but then we have to
-compose with ${\cal C}(R_i,D)$ more selectively.
-In particular, if we have
-\begin{equation}
-\label{eq:transitive:right}
-\text{for each $j \ne i$ either }
-\domain R_j \subseteq D \text{ or } \domain R_j \cap \range R_i = \emptyset
-\end{equation}
-and, similarly,
-\begin{equation}
-\label{eq:transitive:left}
-\text{for each $j \ne i$ either }
-\range R_j \subseteq D \text{ or } \range R_j \cap \domain R_i = \emptyset
-\end{equation}
-then we can refine \eqref{eq:transitive:incremental} to
-$$
-R_i^+ \cup
-\left(
-\left(
-\bigcup_{\shortstack{$\scriptstyle\domain R_j \subseteq D $\\
-		     $\scriptstyle\range R_j \subseteq D$}}
-{\cal C} \circ R_j \circ {\cal C}
-\right)
-\cup
-\left(
-\bigcup_{\shortstack{$\scriptstyle\domain R_j \cap \range R_i = \emptyset$\\
-		     $\scriptstyle\range R_j \subseteq D$}}
-\!\!\!\!\!
-{\cal C} \circ R_j
-\right)
-\cup
-\left(
-\bigcup_{\shortstack{$\scriptstyle\domain R_j \subseteq D $\\
-		     $\scriptstyle\range R_j \cap \domain R_i = \emptyset$}}
-\!\!\!\!\!
-R_j \circ {\cal C}
-\right)
-\cup
-\left(
-\bigcup_{\shortstack{$\scriptstyle\domain R_j \cap \range R_i = \emptyset$\\
-		     $\scriptstyle\range R_j \cap \domain R_i = \emptyset$}}
-\!\!\!\!\!
-R_j
-\right)
-\right)^+
-.
-$$
-If only property~\eqref{eq:transitive:right} holds,
-we can use
-$$
-R_i^+ \cup
-\left(
-\left(
-R_i^+ \cup \identity
-\right)
-\circ
-\left(
-\left(
-\bigcup_{\shortstack{$\scriptstyle\domain R_j \subseteq D $}}
-R_j \circ {\cal C}
-\right)
-\cup
-\left(
-\bigcup_{\shortstack{$\scriptstyle\domain R_j \cap \range R_i = \emptyset$}}
-\!\!\!\!\!
-R_j
-\right)
-\right)^+
-\right)
-,
-$$
-while if only property~\eqref{eq:transitive:left} holds,
-we can use
-$$
-R_i^+ \cup
-\left(
-\left(
-\left(
-\bigcup_{\shortstack{$\scriptstyle\range R_j \subseteq D $}}
-{\cal C} \circ R_j
-\right)
-\cup
-\left(
-\bigcup_{\shortstack{$\scriptstyle\range R_j \cap \domain R_i = \emptyset$}}
-\!\!\!\!\!
-R_j
-\right)
-\right)^+
-\circ
-\left(
-R_i^+ \cup \identity
-\right)
-\right)
-.
-$$
-
-It should be noted that if we want the result of the incremental
-approach to be transitively closed, then we can only apply it
-if all of the transitive closure operations involved are exact.
-If, say, the second transitive closure in \eqref{eq:transitive:incremental}
-contains extra elements, then the result does not necessarily contain
-the composition of these extra elements with powers of $R_i$.
-
-\subsection{An {\tt Omega}-like implementation}
-
-While the main algorithm of \shortciteN{Kelly1996closure} is
-designed to compute and underapproximation of the transitive closure,
-the authors mention that they could also compute overapproximations.
-In this section, we describe our implementation of an algorithm
-that is based on their ideas.
-Note that the {\tt Omega} library computes underapproximations
-\shortcite[Section 6.4]{Omega_lib}.
-
-The main tool is Equation~(2) of \shortciteN{Kelly1996closure}.
-The input relation $R$ is first overapproximated by a ``d-form'' relation
-$$
-\{\, \vec i \to \vec j \mid \exists \vec \alpha :
-\vec L \le \vec j - \vec i \le \vec U
-\wedge
-(\forall p : j_p - i_p = M_p \alpha_p)
-\,\}
-,
-$$
-where $p$ ranges over the dimensions and $\vec L$, $\vec U$ and
-$\vec M$ are constant integer vectors.  The elements of $\vec U$
-may be $\infty$, meaning that there is no upper bound corresponding
-to that element, and similarly for $\vec L$.
-Such an overapproximation can be obtained by computing strides,
-lower and upper bounds on the difference set $\Delta \, R$.
-The transitive closure of such a ``d-form'' relation is
-\begin{equation}
-\label{eq:omega}
-\{\, \vec i \to \vec j \mid \exists \vec \alpha, k :
-k \ge 1 \wedge
-k \, \vec L \le \vec j - \vec i \le k \, \vec U
-\wedge
-(\forall p : j_p - i_p = M_p \alpha_p)
-\,\}
-.
-\end{equation}
-The domain and range of this transitive closure are then
-intersected with those of the input relation.
-This is a special case of the algorithm in \autoref{s:power}.
-
-In their algorithm for computing lower bounds, the authors
-use the above algorithm as a substep on the disjuncts in the relation.
-At the end, they say
-\begin{quote}
-If an upper bound is required, it can be calculated in a manner
-similar to that of a single conjunct [sic] relation.
-\end{quote}
-Presumably, the authors mean that a ``d-form'' approximation
-of the whole input relation should be used.
-However, the accuracy can be improved by also trying to
-apply the incremental technique from the same paper,
-which is explained in more detail in \autoref{s:incremental}.
-In this case, ${\cal C}(R_i,D)$ can be obtained by
-allowing the value zero for $k$ in \eqref{eq:omega},
-i.e., by computing
-$$
-\{\, \vec i \to \vec j \mid \exists \vec \alpha, k :
-k \ge 0 \wedge
-k \, \vec L \le \vec j - \vec i \le k \, \vec U
-\wedge
-(\forall p : j_p - i_p = M_p \alpha_p)
-\,\}
-.
-$$
-In our implementation we take as $D$ the simple hull
-(\autoref{s:simple hull}) of $\domain R \cup \range R$.
-To determine whether it is safe to use ${\cal C}(R_i,D)$,
-we check the following conditions, as proposed by
-\shortciteN{Kelly1996closure}:
-${\cal C}(R_i,D) - R_i^+$ is not a union and for each $j \ne i$
-the condition
-$$
-\left({\cal C}(R_i,D) - R_i^+\right)
-\circ
-R_j
-\circ
-\left({\cal C}(R_i,D) - R_i^+\right)
-=
-R_j
-$$
-holds.

-  ABSTRACT = {  Parallel computers are difficult to program efficiently.  We believe
-  that a good way to help programmers write efficient programs is to
-  provide them with tools that show them how their programs behave on
-  a parallel computer.  Data distribution is the major performance
-  factor of data-parallel programs and so automatic data layout for
-  HPF programs has been studied by many researchers recently.  The
-  communication volume induced by a data distribution is a good
-  estimator of the efficiency of this data distribution.
-
-  We present here a symbolic method to compute the communication
-  volume generated by a given data distribution during the program
-  writing phase (before compilation). We stay machine-independent to
-  assure portability.  Our goal is to help the programmer understand
-  the data movements its program generates and thus find a good data
-  distribution. Our method is based on parametric polyhedral
-  computations. It can be applied to a large class of regular codes.},

-=head1 Introduction
-
-C<isl> is a thread-safe C library for manipulating
-sets and relations of integer points bounded by affine constraints.
-The descriptions of the sets and relations may involve
-both parameters and existentially quantified variables.
-All computations are performed in exact integer arithmetic
-using C<GMP>.
-The C<isl> library offers functionality that is similar
-to that offered by the C<Omega> and C<Omega+> libraries,
-but the underlying algorithms are in most cases completely different.
-
-The library is by no means complete and some fairly basic
-functionality is still missing.
-Still, even in its current form, the library has been successfully
-used as a backend polyhedral library for the polyhedral
-scanner C<CLooG> and as part of an equivalence checker of
-static affine programs.
-For bug reports, feature requests and questions,
-visit the the discussion group at
-L<http://groups.google.com/group/isl-development>.

-=head2 Backward Incompatible Changes
-
-=head3 Changes since isl-0.02
-
-=over
-
-=item * The old printing functions have been deprecated
-and replaced by C<isl_printer> functions, see L<Input and Output>.
-
-=item * Most functions related to dependence analysis have acquired
-an extra C<must> argument.  To obtain the old behavior, this argument
-should be given the value 1.  See L<Dependence Analysis>.
-
-=back
-
-=head3 Changes since isl-0.03
-
-=over
-
-=item * The function C<isl_pw_qpolynomial_fold_add> has been
-renamed to C<isl_pw_qpolynomial_fold_fold>.
-Similarly, C<isl_union_pw_qpolynomial_fold_add> has been
-renamed to C<isl_union_pw_qpolynomial_fold_fold>.
-
-=back
-
-=head3 Changes since isl-0.04
-

-
-=item * All header files have been renamed from C<isl_header.h>
-to C<isl/header.h>.
-
-=back
-
-=head3 Changes since isl-0.05
-
-=over
-
-=item * The functions C<isl_printer_print_basic_set> and
-C<isl_printer_print_basic_map> no longer print a newline.
-
-=item * The functions C<isl_flow_get_no_source>
-and C<isl_union_map_compute_flow> now return
-the accesses for which no source could be found instead of
-the iterations where those accesses occur.
-
-=item * The functions C<isl_basic_map_identity> and
-C<isl_map_identity> now take a B<map> space as input.  An old call
-C<isl_map_identity(space)> can be rewritten to
-C<isl_map_identity(isl_space_map_from_set(space))>.
-
-=item * The function C<isl_map_power> no longer takes
-a parameter position as input.  Instead, the exponent
-is now expressed as the domain of the resulting relation.
-
-=back
-
-=head3 Changes since isl-0.06
-
-=over
-
-=item * The format of C<isl_printer_print_qpolynomial>'s
-C<ISL_FORMAT_ISL> output has changed.
-Use C<ISL_FORMAT_C> to obtain the old output.
-
-=item * The C<*_fast_*> functions have been renamed to C<*_plain_*>.
-Some of the old names have been kept for backward compatibility,
-but they will be removed in the future.
-
-=back
-
-=head3 Changes since isl-0.07
-
-=over
-
-=item * The function C<isl_pw_aff_max> has been renamed to
-C<isl_pw_aff_union_max>.
-Similarly, the function C<isl_pw_aff_add> has been renamed to
-C<isl_pw_aff_union_add>.
-
-=item * The C<isl_dim> type has been renamed to C<isl_space>
-along with the associated functions.
-Some of the old names have been kept for backward compatibility,
-but they will be removed in the future.
-
-=item * Spaces of maps, sets and parameter domains are now
-treated differently.  The distinction between map spaces and set spaces
-has always been made on a conceptual level, but proper use of such spaces
-was never checked.  Furthermore, up until isl-0.07 there was no way
-of explicitly creating a parameter space.  These can now be created
-directly using C<isl_space_params_alloc> or from other spaces using
-C<isl_space_params>.
-
-=item * The space in which C<isl_aff>, C<isl_pw_aff>, C<isl_qpolynomial>,
-C<isl_pw_qpolynomial>, C<isl_qpolynomial_fold> and C<isl_pw_qpolynomial_fold>
-objects live is now a map space
-instead of a set space.  This means, for example, that the dimensions
-of the domain of an C<isl_aff> are now considered to be of type
-C<isl_dim_in> instead of C<isl_dim_set>.  Extra functions have been
-added to obtain the domain space.  Some of the constructors still
-take a domain space and have therefore been renamed.
-
-=item * The functions C<isl_equality_alloc> and C<isl_inequality_alloc>
-now take an C<isl_local_space> instead of an C<isl_space>.
-An C<isl_local_space> can be created from an C<isl_space>
-using C<isl_local_space_from_space>.
-
-=item * The C<isl_div> type has been removed.  Functions that used
-to return an C<isl_div> now return an C<isl_aff>.
-Note that the space of an C<isl_aff> is that of relation.
-When replacing a call to C<isl_div_get_coefficient> by a call to
-C<isl_aff_get_coefficient> any C<isl_dim_set> argument needs
-to be replaced by C<isl_dim_in>.
-A call to C<isl_aff_from_div> can be replaced by a call
-to C<isl_aff_floor>.
-A call to C<isl_qpolynomial_div(div)> call be replaced by
-the nested call
-
-	isl_qpolynomial_from_aff(isl_aff_floor(div))
-
-The function C<isl_constraint_div> has also been renamed
-to C<isl_constraint_get_div>.
-
-=item * The C<nparam> argument has been removed from
-C<isl_map_read_from_str> and similar functions.
-When reading input in the original PolyLib format,
-the result will have no parameters.
-If parameters are expected, the caller may want to perform
-dimension manipulation on the result.

-
-=head1 Installation
-
-The source of C<isl> can be obtained either as a tarball
-or from the git repository.  Both are available from
-L<http://freshmeat.net/projects/isl/>.
-The installation process depends on how you obtained
-the source.
-
-=head2 Installation from the git repository
-
-=over
-
-=item 1 Clone or update the repository
-
-The first time the source is obtained, you need to clone
-the repository.
-
-	git clone git://repo.or.cz/isl.git
-
-To obtain updates, you need to pull in the latest changes
-
-	git pull
-
-=item 2 Generate C<configure>
-
-	./autogen.sh
-
-=back
-
-After performing the above steps, continue
-with the L<Common installation instructions>.
-
-=head2 Common installation instructions
-
-=over
-
-=item 1 Obtain C<GMP>
-
-Building C<isl> requires C<GMP>, including its headers files.
-Your distribution may not provide these header files by default
-and you may need to install a package called C<gmp-devel> or something
-similar.  Alternatively, C<GMP> can be built from
-source, available from L<http://gmplib.org/>.
-
-=item 2 Configure
-
-C<isl> uses the standard C<autoconf> C<configure> script.
-To run it, just type
-
-	./configure
-
-optionally followed by some configure options.
-A complete list of options can be obtained by running
-
-	./configure --help
-
-Below we discuss some of the more common options.
-
-C<isl> can optionally use C<piplib>, but no
-C<piplib> functionality is currently used by default.
-The C<--with-piplib> option can
-be used to specify which C<piplib>
-library to use, either an installed version (C<system>),
-an externally built version (C<build>)
-or no version (C<no>).  The option C<build> is mostly useful
-in C<configure> scripts of larger projects that bundle both C<isl>
-and C<piplib>.

-=head1 Library
-
-=head2 Initialization
-
-All manipulations of integer sets and relations occur within
-the context of an C<isl_ctx>.
-A given C<isl_ctx> can only be used within a single thread.
-All arguments of a function are required to have been allocated
-within the same context.
-There are currently no functions available for moving an object
-from one C<isl_ctx> to another C<isl_ctx>.  This means that
-there is currently no way of safely moving an object from one
-thread to another, unless the whole C<isl_ctx> is moved.
-
-An C<isl_ctx> can be allocated using C<isl_ctx_alloc> and
-freed using C<isl_ctx_free>.
-All objects allocated within an C<isl_ctx> should be freed
-before the C<isl_ctx> itself is freed.
-
-	isl_ctx *isl_ctx_alloc();
-	void isl_ctx_free(isl_ctx *ctx);
-
-=head2 Integers
-
-All operations on integers, mainly the coefficients
-of the constraints describing the sets and relations,
-are performed in exact integer arithmetic using C<GMP>.
-However, to allow future versions of C<isl> to optionally
-support fixed integer arithmetic, all calls to C<GMP>
-are wrapped inside C<isl> specific macros.
-The basic type is C<isl_int> and the operations below
-are available on this type.
-The meanings of these operations are essentially the same
-as their C<GMP> C<mpz_> counterparts.
-As always with C<GMP> types, C<isl_int>s need to be
-initialized with C<isl_int_init> before they can be used
-and they need to be released with C<isl_int_clear>
-after the last use.
-The user should not assume that an C<isl_int> is represented
-as a C<mpz_t>, but should instead explicitly convert between
-C<mpz_t>s and C<isl_int>s using C<isl_int_set_gmp> and
-C<isl_int_get_gmp> whenever a C<mpz_t> is required.

-=head2 Sets and Relations
-
-C<isl> uses six types of objects for representing sets and relations,
-C<isl_basic_set>, C<isl_basic_map>, C<isl_set>, C<isl_map>,
-C<isl_union_set> and C<isl_union_map>.
-C<isl_basic_set> and C<isl_basic_map> represent sets and relations that
-can be described as a conjunction of affine constraints, while
-C<isl_set> and C<isl_map> represent unions of
-C<isl_basic_set>s and C<isl_basic_map>s, respectively.
-However, all C<isl_basic_set>s or C<isl_basic_map>s in the union need
-to live in the same space.  C<isl_union_set>s and C<isl_union_map>s
-represent unions of C<isl_set>s or C<isl_map>s in I<different> spaces,
-where spaces are considered different if they have a different number
-of dimensions and/or different names (see L<"Spaces">).
-The difference between sets and relations (maps) is that sets have
-one set of variables, while relations have two sets of variables,
-input variables and output variables.
-
-=head2 Memory Management
-
-Since a high-level operation on sets and/or relations usually involves
-several substeps and since the user is usually not interested in
-the intermediate results, most functions that return a new object
-will also release all the objects passed as arguments.
-If the user still wants to use one or more of these arguments
-after the function call, she should pass along a copy of the
-object rather than the object itself.
-The user is then responsible for making sure that the original
-object gets used somewhere else or is explicitly freed.
-
-The arguments and return values of all documented functions are
-annotated to make clear which arguments are released and which
-arguments are preserved.  In particular, the following annotations
-are used
-
-=over
-
-=item C<__isl_give>
-
-C<__isl_give> means that a new object is returned.
-The user should make sure that the returned pointer is
-used exactly once as a value for an C<__isl_take> argument.
-In between, it can be used as a value for as many
-C<__isl_keep> arguments as the user likes.
-There is one exception, and that is the case where the
-pointer returned is C<NULL>.  Is this case, the user
-is free to use it as an C<__isl_take> argument or not.
-
-=item C<__isl_take>
-
-C<__isl_take> means that the object the argument points to
-is taken over by the function and may no longer be used
-by the user as an argument to any other function.
-The pointer value must be one returned by a function
-returning an C<__isl_give> pointer.
-If the user passes in a C<NULL> value, then this will
-be treated as an error in the sense that the function will
-not perform its usual operation.  However, it will still
-make sure that all the other C<__isl_take> arguments
-are released.
-
-=item C<__isl_keep>
-
-C<__isl_keep> means that the function will only use the object
-temporarily.  After the function has finished, the user
-can still use it as an argument to other functions.
-A C<NULL> value will be treated in the same way as
-a C<NULL> value for an C<__isl_take> argument.
-
-=back
-
-=head2 Error Handling
-
-C<isl> supports different ways to react in case a runtime error is triggered.
-Runtime errors arise, e.g., if a function such as C<isl_map_intersect> is called
-with two maps that have incompatible spaces. There are three possible ways
-to react on error: to warn, to continue or to abort.
-
-The default behavior is to warn. In this mode, C<isl> prints a warning, stores
-the last error in the corresponding C<isl_ctx> and the function in which the
-error was triggered returns C<NULL>. An error does not corrupt internal state,
-such that isl can continue to be used. C<isl> also provides functions to
-read the last error and to reset the memory that stores the last error. The
-last error is only stored for information purposes. Its presence does not
-change the behavior of C<isl>. Hence, resetting an error is not required to
-continue to use isl, but only to observe new errors.
-
-	#include <isl/ctx.h>
-	enum isl_error isl_ctx_last_error(isl_ctx *ctx);
-	void isl_ctx_reset_error(isl_ctx *ctx);
-
-Another option is to continue on error. This is similar to warn on error mode,
-except that C<isl> does not print any warning. This allows a program to
-implement its own error reporting.
-
-The last option is to directly abort the execution of the program from within
-the isl library. This makes it obviously impossible to recover from an error,
-but it allows to directly spot the error location. By aborting on error,
-debuggers break at the location the error occurred and can provide a stack
-trace. Other tools that automatically provide stack traces on abort or that do
-not want to continue execution after an error was triggered may also prefer to
-abort on error.
-
-The on error behavior of isl can be specified by calling
-C<isl_options_set_on_error> or by setting the command line option
-C<--isl-on-error>. Valid arguments for the function call are
-C<ISL_ON_ERROR_WARN>, C<ISL_ON_ERROR_CONTINUE> and C<ISL_ON_ERROR_ABORT>. The
-choices for the command line option are C<warn>, C<continue> and C<abort>.
-It is also possible to query the current error mode.
-
-	#include <isl/options.h>
-	int isl_options_set_on_error(isl_ctx *ctx, int val);
-	int isl_options_get_on_error(isl_ctx *ctx);
-
-=head2 Identifiers
-
-Identifiers are used to identify both individual dimensions
-and tuples of dimensions.  They consist of a name and an optional
-pointer.  Identifiers with the same name but different pointer values
-are considered to be distinct.
-Identifiers can be constructed, copied, freed, inspected and printed
-using the following functions.
-
-	#include <isl/id.h>
-	__isl_give isl_id *isl_id_alloc(isl_ctx *ctx,
-		__isl_keep const char *name, void *user);
-	__isl_give isl_id *isl_id_copy(isl_id *id);
-	void *isl_id_free(__isl_take isl_id *id);
-
-	isl_ctx *isl_id_get_ctx(__isl_keep isl_id *id);
-	void *isl_id_get_user(__isl_keep isl_id *id);
-	__isl_keep const char *isl_id_get_name(__isl_keep isl_id *id);

-=head2 Spaces
-
-Whenever a new set or relation is created from scratch,
-the space in which it lives needs to be specified using an C<isl_space>.
-
-	#include <isl/space.h>
-	__isl_give isl_space *isl_space_alloc(isl_ctx *ctx,
-		unsigned nparam, unsigned n_in, unsigned n_out);
-	__isl_give isl_space *isl_space_params_alloc(isl_ctx *ctx,
-		unsigned nparam);
-	__isl_give isl_space *isl_space_set_alloc(isl_ctx *ctx,
-		unsigned nparam, unsigned dim);
-	__isl_give isl_space *isl_space_copy(__isl_keep isl_space *space);
-	void isl_space_free(__isl_take isl_space *space);
-	unsigned isl_space_dim(__isl_keep isl_space *space,
-		enum isl_dim_type type);
-
-The space used for creating a parameter domain
-needs to be created using C<isl_space_params_alloc>.
-For other sets, the space
-needs to be created using C<isl_space_set_alloc>, while
-for a relation, the space
-needs to be created using C<isl_space_alloc>.
-C<isl_space_dim> can be used
-to find out the number of dimensions of each type in
-a space, where type may be
-C<isl_dim_param>, C<isl_dim_in> (only for relations),
-C<isl_dim_out> (only for relations), C<isl_dim_set>
-(only for sets) or C<isl_dim_all>.
-
-To check whether a given space is that of a set or a map
-or whether it is a parameter space, use these functions:
-
-	#include <isl/space.h>
-	int isl_space_is_params(__isl_keep isl_space *space);
-	int isl_space_is_set(__isl_keep isl_space *space);
-
-It is often useful to create objects that live in the
-same space as some other object.  This can be accomplished
-by creating the new objects
-(see L<Creating New Sets and Relations> or
-L<Creating New (Piecewise) Quasipolynomials>) based on the space
-of the original object.

-The identifiers or names of the individual dimensions may be set or read off
-using the following functions.
-
-	#include <isl/space.h>
-	__isl_give isl_space *isl_space_set_dim_id(
-		__isl_take isl_space *space,

-				 __isl_keep const char *name);
-	__isl_keep const char *isl_space_get_dim_name(__isl_keep isl_space *space,
-				 enum isl_dim_type type, unsigned pos);
-
-Note that C<isl_space_get_name> returns a pointer to some internal
-data structure, so the result can only be used while the
-corresponding C<isl_space> is alive.
-Also note that every function that operates on two sets or relations
-requires that both arguments have the same parameters.  This also
-means that if one of the arguments has named parameters, then the
-other needs to have named parameters too and the names need to match.
-Pairs of C<isl_set>, C<isl_map>, C<isl_union_set> and/or C<isl_union_map>
-arguments may have different parameters (as long as they are named),
-in which case the result will have as parameters the union of the parameters of
-the arguments.
-
-Given the identifier or name of a dimension (typically a parameter),
-its position can be obtained from the following function.
-
-	#include <isl/space.h>
-	int isl_space_find_dim_by_id(__isl_keep isl_space *space,
-		enum isl_dim_type type, __isl_keep isl_id *id);
-	int isl_space_find_dim_by_name(__isl_keep isl_space *space,
-		enum isl_dim_type type, const char *name);
-
-The identifiers or names of entire spaces may be set or read off
-using the following functions.
-
-	#include <isl/space.h>
-	__isl_give isl_space *isl_space_set_tuple_id(
-		__isl_take isl_space *space,

-	const char *isl_space_get_tuple_name(__isl_keep isl_space *space,
-		enum isl_dim_type type);
-
-The C<type> argument needs to be one of C<isl_dim_in>, C<isl_dim_out>
-or C<isl_dim_set>.  As with C<isl_space_get_name>,
-the C<isl_space_get_tuple_name> function returns a pointer to some internal
-data structure.
-Binary operations require the corresponding spaces of their arguments
-to have the same name.
-
-Spaces can be nested.  In particular, the domain of a set or
-the domain or range of a relation can be a nested relation.
-The following functions can be used to construct and deconstruct
-such nested spaces.
-
-	#include <isl/space.h>
-	int isl_space_is_wrapping(__isl_keep isl_space *space);
-	__isl_give isl_space *isl_space_wrap(__isl_take isl_space *space);
-	__isl_give isl_space *isl_space_unwrap(__isl_take isl_space *space);
-
-The input to C<isl_space_is_wrapping> and C<isl_space_unwrap> should
-be the space of a set, while that of
-C<isl_space_wrap> should be the space of a relation.
-Conversely, the output of C<isl_space_unwrap> is the space
-of a relation, while that of C<isl_space_wrap> is the space of a set.
-
-Spaces can be created from other spaces
-using the following functions.
-
-	__isl_give isl_space *isl_space_domain(__isl_take isl_space *space);
-	__isl_give isl_space *isl_space_from_domain(__isl_take isl_space *space);

-=head2 Local Spaces
-
-A local space is essentially a space with
-zero or more existentially quantified variables.
-The local space of a basic set or relation can be obtained
-using the following functions.

-	#include <isl/local_space.h>
-	__isl_give isl_local_space *isl_local_space_from_space(
-		__isl_take isl_space *space);
-
-They can be inspected, modified, copied and freed using the following functions.
-
-	#include <isl/local_space.h>
-	isl_ctx *isl_local_space_get_ctx(
-		__isl_keep isl_local_space *ls);
-	int isl_local_space_is_set(__isl_keep isl_local_space *ls);

-=head2 Input and Output
-
-C<isl> supports its own input/output format, which is similar
-to the C<Omega> format, but also supports the C<PolyLib> format
-in some cases.
-
-=head3 C<isl> format
-
-The C<isl> format is similar to that of C<Omega>, but has a different
-syntax for describing the parameters and allows for the definition
-of an existentially quantified variable as the integer division
-of an affine expression.
-For example, the set of integers C<i> between C<0> and C<n>
-such that C<i % 10 <= 6> can be described as
-
-	[n] -> { [i] : exists (a = [i/10] : 0 <= i and i <= n and
-				i - 10 a <= 6) }
-
-A set or relation can have several disjuncts, separated
-by the keyword C<or>.  Each disjunct is either a conjunction
-of constraints or a projection (C<exists>) of a conjunction
-of constraints.  The constraints are separated by the keyword
-C<and>.
-
-=head3 C<PolyLib> format
-
-If the represented set is a union, then the first line
-contains a single number representing the number of disjuncts.
-Otherwise, a line containing the number C<1> is optional.
-
-Each disjunct is represented by a matrix of constraints.
-The first line contains two numbers representing
-the number of rows and columns,
-where the number of rows is equal to the number of constraints
-and the number of columns is equal to two plus the number of variables.
-The following lines contain the actual rows of the constraint matrix.
-In each row, the first column indicates whether the constraint
-is an equality (C<0>) or inequality (C<1>).  The final column
-corresponds to the constant term.
-
-If the set is parametric, then the coefficients of the parameters
-appear in the last columns before the constant column.
-The coefficients of any existentially quantified variables appear
-between those of the set variables and those of the parameters.
-
-=head3 Extended C<PolyLib> format
-
-The extended C<PolyLib> format is nearly identical to the
-C<PolyLib> format.  The only difference is that the line
-containing the number of rows and columns of a constraint matrix
-also contains four additional numbers:
-the number of output dimensions, the number of input dimensions,
-the number of local dimensions (i.e., the number of existentially
-quantified variables) and the number of parameters.
-For sets, the number of ``output'' dimensions is equal
-to the number of set dimensions, while the number of ``input''
-dimensions is zero.

-and defaults to C<ISL_FORMAT_ISL>.
-Each line in the output is indented by C<indent> (set by

-(default: 0), prefixed by C<prefix> and suffixed by C<suffix>.

-=head2 Inspecting Sets and Relations
-
-Usually, the user should not have to care about the actual constraints
-of the sets and maps, but should instead apply the abstract operations
-explained in the following sections.
-Occasionally, however, it may be required to inspect the individual
-coefficients of the constraints.  This section explains how to do so.
-In these cases, it may also be useful to have C<isl> compute
-an explicit representation of the existentially quantified variables.
-
-	__isl_give isl_set *isl_set_compute_divs(
-		__isl_take isl_set *set);
-	__isl_give isl_map *isl_map_compute_divs(
-		__isl_take isl_map *map);
-	__isl_give isl_union_set *isl_union_set_compute_divs(
-		__isl_take isl_union_set *uset);
-	__isl_give isl_union_map *isl_union_map_compute_divs(
-		__isl_take isl_union_map *umap);
-
-This explicit representation defines the existentially quantified
-variables as integer divisions of the other variables, possibly
-including earlier existentially quantified variables.
-An explicitly represented existentially quantified variable therefore
-has a unique value when the values of the other variables are known.
-If, furthermore, the same existentials, i.e., existentials
-with the same explicit representations, should appear in the
-same order in each of the disjuncts of a set or map, then the user should call
-either of the following functions.
-
-	__isl_give isl_set *isl_set_align_divs(
-		__isl_take isl_set *set);
-	__isl_give isl_map *isl_map_align_divs(
-		__isl_take isl_map *map);
-
-Alternatively, the existentially quantified variables can be removed
-using the following functions, which compute an overapproximation.
-
-	__isl_give isl_basic_set *isl_basic_set_remove_divs(
-		__isl_take isl_basic_set *bset);
-	__isl_give isl_basic_map *isl_basic_map_remove_divs(
-		__isl_take isl_basic_map *bmap);
-	__isl_give isl_set *isl_set_remove_divs(
-		__isl_take isl_set *set);
-	__isl_give isl_map *isl_map_remove_divs(
-		__isl_take isl_map *map);
-
-To iterate over all the sets or maps in a union set or map, use
-
-	int isl_union_set_foreach_set(__isl_keep isl_union_set *uset,
-		int (*fn)(__isl_take isl_set *set, void *user),
-		void *user);
-	int isl_union_map_foreach_map(__isl_keep isl_union_map *umap,
-		int (*fn)(__isl_take isl_map *map, void *user),
-		void *user);
-
-The number of sets or maps in a union set or map can be obtained
-from
-
-	int isl_union_set_n_set(__isl_keep isl_union_set *uset);
-	int isl_union_map_n_map(__isl_keep isl_union_map *umap);
-
-To extract the set or map in a given space from a union, use
-
-	__isl_give isl_set *isl_union_set_extract_set(
-		__isl_keep isl_union_set *uset,
-		__isl_take isl_space *space);
-	__isl_give isl_map *isl_union_map_extract_map(
-		__isl_keep isl_union_map *umap,
-		__isl_take isl_space *space);
-
-To iterate over all the basic sets or maps in a set or map, use
-
-	int isl_set_foreach_basic_set(__isl_keep isl_set *set,
-		int (*fn)(__isl_take isl_basic_set *bset, void *user),
-		void *user);
-	int isl_map_foreach_basic_map(__isl_keep isl_map *map,
-		int (*fn)(__isl_take isl_basic_map *bmap, void *user),
-		void *user);
-
-The callback function C<fn> should return 0 if successful and
--1 if an error occurs.  In the latter case, or if any other error
-occurs, the above functions will return -1.
-
-It should be noted that C<isl> does not guarantee that
-the basic sets or maps passed to C<fn> are disjoint.
-If this is required, then the user should call one of
-the following functions first.
-
-	__isl_give isl_set *isl_set_make_disjoint(
-		__isl_take isl_set *set);
-	__isl_give isl_map *isl_map_make_disjoint(
-		__isl_take isl_map *map);
-
-The number of basic sets in a set can be obtained
-from
-
-	int isl_set_n_basic_set(__isl_keep isl_set *set);
-
-To iterate over the constraints of a basic set or map, use
-
-	#include <isl/constraint.h>
-
-	int isl_basic_map_foreach_constraint(
-		__isl_keep isl_basic_map *bmap,
-		int (*fn)(__isl_take isl_constraint *c, void *user),
-		void *user);
-	void *isl_constraint_free(__isl_take isl_constraint *c);
-
-Again, the callback function C<fn> should return 0 if successful and
--1 if an error occurs.  In the latter case, or if any other error
-occurs, the above functions will return -1.
-The constraint C<c> represents either an equality or an inequality.
-Use the following function to find out whether a constraint
-represents an equality.  If not, it represents an inequality.
-
-	int isl_constraint_is_equality(
-		__isl_keep isl_constraint *constraint);
-
-The coefficients of the constraints can be inspected using
-the following functions.
-
-	void isl_constraint_get_constant(
-		__isl_keep isl_constraint *constraint, isl_int *v);
-	void isl_constraint_get_coefficient(
-		__isl_keep isl_constraint *constraint,
-		enum isl_dim_type type, int pos, isl_int *v);
-	int isl_constraint_involves_dims(
-		__isl_keep isl_constraint *constraint,
-		enum isl_dim_type type, unsigned first, unsigned n);
-
-The explicit representations of the existentially quantified
-variables can be inspected using the following function.
-Note that the user is only allowed to use this function
-if the inspected set or map is the result of a call
-to C<isl_set_compute_divs> or C<isl_map_compute_divs>.
-The existentially quantified variable is equal to the floor
-of the returned affine expression.  The affine expression
-itself can be inspected using the functions in
-L<"Piecewise Quasi Affine Expressions">.
-
-	__isl_give isl_aff *isl_constraint_get_div(
-		__isl_keep isl_constraint *constraint, int pos);
-
-To obtain the constraints of a basic set or map in matrix
-form, use the following functions.
-
-	__isl_give isl_mat *isl_basic_set_equalities_matrix(
-		__isl_keep isl_basic_set *bset,
-		enum isl_dim_type c1, enum isl_dim_type c2,
-		enum isl_dim_type c3, enum isl_dim_type c4);
-	__isl_give isl_mat *isl_basic_set_inequalities_matrix(
-		__isl_keep isl_basic_set *bset,
-		enum isl_dim_type c1, enum isl_dim_type c2,
-		enum isl_dim_type c3, enum isl_dim_type c4);
-	__isl_give isl_mat *isl_basic_map_equalities_matrix(
-		__isl_keep isl_basic_map *bmap,
-		enum isl_dim_type c1,
-		enum isl_dim_type c2, enum isl_dim_type c3,
-		enum isl_dim_type c4, enum isl_dim_type c5);
-	__isl_give isl_mat *isl_basic_map_inequalities_matrix(
-		__isl_keep isl_basic_map *bmap,
-		enum isl_dim_type c1,
-		enum isl_dim_type c2, enum isl_dim_type c3,
-		enum isl_dim_type c4, enum isl_dim_type c5);
-
-The C<isl_dim_type> arguments dictate the order in which
-different kinds of variables appear in the resulting matrix
-and should be a permutation of C<isl_dim_cst>, C<isl_dim_param>,
-C<isl_dim_in>, C<isl_dim_out> and C<isl_dim_div>.
-
-The number of parameters, input, output or set dimensions can
-be obtained using the following functions.
-
-	unsigned isl_basic_set_dim(__isl_keep isl_basic_set *bset,
-		enum isl_dim_type type);
-	unsigned isl_basic_map_dim(__isl_keep isl_basic_map *bmap,
-		enum isl_dim_type type);
-	unsigned isl_set_dim(__isl_keep isl_set *set,
-		enum isl_dim_type type);
-	unsigned isl_map_dim(__isl_keep isl_map *map,
-		enum isl_dim_type type);
-
-To check whether the description of a set or relation depends
-on one or more given dimensions, it is not necessary to iterate over all
-constraints.  Instead the following functions can be used.
-
-	int isl_basic_set_involves_dims(
-		__isl_keep isl_basic_set *bset,
-		enum isl_dim_type type, unsigned first, unsigned n);
-	int isl_set_involves_dims(__isl_keep isl_set *set,

-		enum isl_dim_type type, unsigned first, unsigned n);
-	int isl_map_involves_dims(__isl_keep isl_map *map,
-		enum isl_dim_type type, unsigned first, unsigned n);
-
-Similarly, the following functions can be used to check whether
-a given dimension is involved in any lower or upper bound.
-
-	int isl_set_dim_has_lower_bound(__isl_keep isl_set *set,
-		enum isl_dim_type type, unsigned pos);
-	int isl_set_dim_has_upper_bound(__isl_keep isl_set *set,
-		enum isl_dim_type type, unsigned pos);
-
-The identifiers or names of the domain and range spaces of a set

-
-=head2 Points
-
-Points are elements of a set.  They can be used to construct
-simple sets (boxes) or they can be used to represent the
-individual elements of a set.
-The zero point (the origin) can be created using
-
-	__isl_give isl_point *isl_point_zero(__isl_take isl_space *space);
-
-The coordinates of a point can be inspected, set and changed
-using
-
-	int isl_point_get_coordinate(__isl_keep isl_point *pnt,
-		enum isl_dim_type type, int pos, isl_int *v);
-	__isl_give isl_point *isl_point_set_coordinate(
-		__isl_take isl_point *pnt,

-
-	__isl_give isl_point *isl_point_add_ui(

-	__isl_give isl_point *isl_point_sub_ui(
-		__isl_take isl_point *pnt,
-		enum isl_dim_type type, int pos, unsigned val);
-
-Other properties can be obtained using
-
-	isl_ctx *isl_point_get_ctx(__isl_keep isl_point *pnt);
-
-Points can be copied or freed using
-
-	__isl_give isl_point *isl_point_copy(
-		__isl_keep isl_point *pnt);
-	void isl_point_free(__isl_take isl_point *pnt);
-
-A singleton set can be created from a point using
-
-	__isl_give isl_basic_set *isl_basic_set_from_point(
-		__isl_take isl_point *pnt);
-	__isl_give isl_set *isl_set_from_point(
-		__isl_take isl_point *pnt);
-
-and a box can be created from two opposite extremal points using
-
-	__isl_give isl_basic_set *isl_basic_set_box_from_points(
-		__isl_take isl_point *pnt1,
-		__isl_take isl_point *pnt2);
-	__isl_give isl_set *isl_set_box_from_points(
-		__isl_take isl_point *pnt1,
-		__isl_take isl_point *pnt2);
-
-All elements of a B<bounded> (union) set can be enumerated using
-the following functions.
-
-	int isl_set_foreach_point(__isl_keep isl_set *set,
-		int (*fn)(__isl_take isl_point *pnt, void *user),
-		void *user);
-	int isl_union_set_foreach_point(__isl_keep isl_union_set *uset,
-		int (*fn)(__isl_take isl_point *pnt, void *user),
-		void *user);
-
-The function C<fn> is called for each integer point in
-C<set> with as second argument the last argument of
-the C<isl_set_foreach_point> call.  The function C<fn>
-should return C<0> on success and C<-1> on failure.
-In the latter case, C<isl_set_foreach_point> will stop
-enumerating and return C<-1> as well.
-If the enumeration is performed successfully and to completion,
-then C<isl_set_foreach_point> returns C<0>.
-
-To obtain a single point of a (basic) set, use
-
-	__isl_give isl_point *isl_basic_set_sample_point(
-		__isl_take isl_basic_set *bset);
-	__isl_give isl_point *isl_set_sample_point(
-		__isl_take isl_set *set);
-
-If C<set> does not contain any (integer) points, then the
-resulting point will be ``void'', a property that can be
-tested using
-
-	int isl_point_is_void(__isl_keep isl_point *pnt);
-
-=head2 Piecewise Quasipolynomials
-
-A piecewise quasipolynomial is a particular kind of function that maps
-a parametric point to a rational value.
-More specifically, a quasipolynomial is a polynomial expression in greatest
-integer parts of affine expressions of parameters and variables.
-A piecewise quasipolynomial is a subdivision of a given parametric
-domain into disjoint cells with a quasipolynomial associated to
-each cell.  The value of the piecewise quasipolynomial at a given
-point is the value of the quasipolynomial associated to the cell
-that contains the point.  Outside of the union of cells,
-the value is assumed to be zero.
-For example, the piecewise quasipolynomial
-
-	[n] -> { [x] -> ((1 + n) - x) : x <= n and x >= 0 }
-
-maps C<x> to C<1 + n - x> for values of C<x> between C<0> and C<n>.
-A given piecewise quasipolynomial has a fixed domain dimension.
-Union piecewise quasipolynomials are used to contain piecewise quasipolynomials
-defined over different domains.
-Piecewise quasipolynomials are mainly used by the C<barvinok>
-library for representing the number of elements in a parametric set or map.
-For example, the piecewise quasipolynomial above represents
-the number of points in the map
-
-	[n] -> { [x] -> [y] : x,y >= 0 and 0 <= x + y <= n }
-
-=head3 Input and Output

-The output format of the printer
-needs to be set to either C<ISL_FORMAT_ISL> or C<ISL_FORMAT_C>.
-For C<isl_printer_print_union_pw_qpolynomial>, only C<ISL_FORMAT_ISL>
-is supported.
-In case of printing in C<ISL_FORMAT_C>, the user may want
-to set the names of all dimensions

-=head3 Creating New (Piecewise) Quasipolynomials
-
-Some simple quasipolynomials can be created using the following functions.
-More complicated quasipolynomials can be created by applying
-operations such as addition and multiplication
-on the resulting quasipolynomials
-
-	__isl_give isl_qpolynomial *isl_qpolynomial_zero_on_domain(
-		__isl_take isl_space *domain);
-	__isl_give isl_qpolynomial *isl_qpolynomial_one_on_domain(
-		__isl_take isl_space *domain);
-	__isl_give isl_qpolynomial *isl_qpolynomial_infty_on_domain(
-		__isl_take isl_space *domain);
-	__isl_give isl_qpolynomial *isl_qpolynomial_neginfty_on_domain(

-	__isl_give isl_qpolynomial *isl_qpolynomial_from_aff(

-with a one-dimensional range.  The C<domain> argument in some of
-the functions above corresponds to the domain of this map space.
-
-The zero piecewise quasipolynomial or a piecewise quasipolynomial
-with a single cell can be created using the following functions.
-Multiple of these single cell piecewise quasipolynomials can
-be combined to create more complicated piecewise quasipolynomials.
-
-	__isl_give isl_pw_qpolynomial *isl_pw_qpolynomial_zero(

-		__isl_take isl_union_pw_qpolynomial *upwqp,

-
-Quasipolynomials can be copied and freed again using the following
-functions.
-

-
-=head3 Inspecting (Piecewise) Quasipolynomials
-
-To iterate over all piecewise quasipolynomials in a union
-piecewise quasipolynomial, use the following function
-
-	int isl_union_pw_qpolynomial_foreach_pw_qpolynomial(
-		__isl_keep isl_union_pw_qpolynomial *upwqp,
-		int (*fn)(__isl_take isl_pw_qpolynomial *pwqp, void *user),
-		void *user);
-
-To extract the piecewise quasipolynomial in a given space from a union, use
-
-	__isl_give isl_pw_qpolynomial *
-	isl_union_pw_qpolynomial_extract_pw_qpolynomial(
-		__isl_keep isl_union_pw_qpolynomial *upwqp,
-		__isl_take isl_space *space);
-
-To iterate over the cells in a piecewise quasipolynomial,
-use either of the following two functions
-
-	int isl_pw_qpolynomial_foreach_piece(
-		__isl_keep isl_pw_qpolynomial *pwqp,
-		int (*fn)(__isl_take isl_set *set,
-			  __isl_take isl_qpolynomial *qp,
-			  void *user), void *user);
-	int isl_pw_qpolynomial_foreach_lifted_piece(
-		__isl_keep isl_pw_qpolynomial *pwqp,
-		int (*fn)(__isl_take isl_set *set,
-			  __isl_take isl_qpolynomial *qp,
-			  void *user), void *user);
-
-As usual, the function C<fn> should return C<0> on success
-and C<-1> on failure.  The difference between
-C<isl_pw_qpolynomial_foreach_piece> and
-C<isl_pw_qpolynomial_foreach_lifted_piece> is that
-C<isl_pw_qpolynomial_foreach_lifted_piece> will first
-compute unique representations for all existentially quantified
-variables and then turn these existentially quantified variables
-into extra set variables, adapting the associated quasipolynomial
-accordingly.  This means that the C<set> passed to C<fn>
-will not have any existentially quantified variables, but that
-the dimensions of the sets may be different for different
-invocations of C<fn>.
-
-To iterate over all terms in a quasipolynomial,
-use
-
-	int isl_qpolynomial_foreach_term(
-		__isl_keep isl_qpolynomial *qp,
-		int (*fn)(__isl_take isl_term *term,
-			  void *user), void *user);
-
-The terms themselves can be inspected and freed using
-these functions
-
-	unsigned isl_term_dim(__isl_keep isl_term *term,
-		enum isl_dim_type type);
-	void isl_term_get_num(__isl_keep isl_term *term,
-		isl_int *n);
-	void isl_term_get_den(__isl_keep isl_term *term,
-		isl_int *d);
-	int isl_term_get_exp(__isl_keep isl_term *term,
-		enum isl_dim_type type, unsigned pos);
-	__isl_give isl_aff *isl_term_get_div(
-		__isl_keep isl_term *term, unsigned pos);
-	void isl_term_free(__isl_take isl_term *term);
-
-Each term is a product of parameters, set variables and
-integer divisions.  The function C<isl_term_get_exp>
-returns the exponent of a given dimensions in the given term.
-The C<isl_int>s in the arguments of C<isl_term_get_num>
-and C<isl_term_get_den> need to have been initialized
-using C<isl_int_init> before calling these functions.
-
-=head3 Properties of (Piecewise) Quasipolynomials
-
-To check whether a quasipolynomial is actually a constant,
-use the following function.
-
-	int isl_qpolynomial_is_cst(__isl_keep isl_qpolynomial *qp,
-		isl_int *n, isl_int *d);
-
-If C<qp> is a constant and if C<n> and C<d> are not C<NULL>
-then the numerator and denominator of the constant
-are returned in C<*n> and C<*d>, respectively.
-
-To check whether two union piecewise quasipolynomials are
-obviously equal, use
-
-	int isl_union_pw_qpolynomial_plain_is_equal(
-		__isl_keep isl_union_pw_qpolynomial *upwqp1,
-		__isl_keep isl_union_pw_qpolynomial *upwqp2);

-=head2 Bounds on Piecewise Quasipolynomials and Piecewise Quasipolynomial Reductions
-
-A piecewise quasipolynomial reduction is a piecewise
-reduction (or fold) of quasipolynomials.
-In particular, the reduction can be maximum or a minimum.
-The objects are mainly used to represent the result of
-an upper or lower bound on a quasipolynomial over its domain,
-i.e., as the result of the following function.
-
-	__isl_give isl_pw_qpolynomial_fold *isl_pw_qpolynomial_bound(
-		__isl_take isl_pw_qpolynomial *pwqp,
-		enum isl_fold type, int *tight);
-
-	__isl_give isl_union_pw_qpolynomial_fold *isl_union_pw_qpolynomial_bound(
-		__isl_take isl_union_pw_qpolynomial *upwqp,
-		enum isl_fold type, int *tight);
-
-The C<type> argument may be either C<isl_fold_min> or C<isl_fold_max>.
-If C<tight> is not C<NULL>, then C<*tight> is set to C<1>
-is the returned bound is known be tight, i.e., for each value
-of the parameters there is at least
-one element in the domain that reaches the bound.
-If the domain of C<pwqp> is not wrapping, then the bound is computed
-over all elements in that domain and the result has a purely parametric
-domain.  If the domain of C<pwqp> is wrapping, then the bound is
-computed over the range of the wrapped relation.  The domain of the
-wrapped relation becomes the domain of the result.
-
-A (piecewise) quasipolynomial reduction can be copied or freed using the
-following functions.

-=head2 Dependence Analysis
-
-C<isl> contains specialized functionality for performing
-array dataflow analysis.  That is, given a I<sink> access relation
-and a collection of possible I<source> access relations,
-C<isl> can compute relations that describe
-for each iteration of the sink access, which iteration
-of which of the source access relations was the last
-to access the same data element before the given iteration
-of the sink access.
-The resulting dependence relations map source iterations
-to the corresponding sink iterations.
-To compute standard flow dependences, the sink should be
-a read, while the sources should be writes.
-If any of the source accesses are marked as being I<may>
-accesses, then there will be a dependence from the last
-I<must> access B<and> from any I<may> access that follows
-this last I<must> access.
-In particular, if I<all> sources are I<may> accesses,
-then memory based dependence analysis is performed.
-If, on the other hand, all sources are I<must> accesses,
-then value based dependence analysis is performed.
-
-	#include <isl/flow.h>
-
-	typedef int (*isl_access_level_before)(void *first, void *second);
-
-	__isl_give isl_access_info *isl_access_info_alloc(
-		__isl_take isl_map *sink,
-		void *sink_user, isl_access_level_before fn,
-		int max_source);
-	__isl_give isl_access_info *isl_access_info_add_source(
-		__isl_take isl_access_info *acc,
-		__isl_take isl_map *source, int must,
-		void *source_user);
-	void isl_access_info_free(__isl_take isl_access_info *acc);
-
-	__isl_give isl_flow *isl_access_info_compute_flow(
-		__isl_take isl_access_info *acc);
-
-	int isl_flow_foreach(__isl_keep isl_flow *deps,
-		int (*fn)(__isl_take isl_map *dep, int must,
-			  void *dep_user, void *user),
-		void *user);
-	__isl_give isl_map *isl_flow_get_no_source(
-		__isl_keep isl_flow *deps, int must);
-	void isl_flow_free(__isl_take isl_flow *deps);
-
-The function C<isl_access_info_compute_flow> performs the actual
-dependence analysis.  The other functions are used to construct
-the input for this function or to read off the output.
-
-The input is collected in an C<isl_access_info>, which can
-be created through a call to C<isl_access_info_alloc>.
-The arguments to this functions are the sink access relation
-C<sink>, a token C<sink_user> used to identify the sink
-access to the user, a callback function for specifying the
-relative order of source and sink accesses, and the number
-of source access relations that will be added.
-The callback function has type C<int (*)(void *first, void *second)>.
-The function is called with two user supplied tokens identifying
-either a source or the sink and it should return the shared nesting
-level and the relative order of the two accesses.
-In particular, let I<n> be the number of loops shared by
-the two accesses.  If C<first> precedes C<second> textually,
-then the function should return I<2 * n + 1>; otherwise,
-it should return I<2 * n>.
-The sources can be added to the C<isl_access_info> by performing
-(at most) C<max_source> calls to C<isl_access_info_add_source>.
-C<must> indicates whether the source is a I<must> access
-or a I<may> access.  Note that a multi-valued access relation
-should only be marked I<must> if every iteration in the domain
-of the relation accesses I<all> elements in its image.
-The C<source_user> token is again used to identify
-the source access.  The range of the source access relation
-C<source> should have the same dimension as the range
-of the sink access relation.
-The C<isl_access_info_free> function should usually not be
-called explicitly, because it is called implicitly by
-C<isl_access_info_compute_flow>.
-
-The result of the dependence analysis is collected in an
-C<isl_flow>.  There may be elements of
-the sink access for which no preceding source access could be
-found or for which all preceding sources are I<may> accesses.
-The relations containing these elements can be obtained through
-calls to C<isl_flow_get_no_source>, the first with C<must> set
-and the second with C<must> unset.
-In the case of standard flow dependence analysis,
-with the sink a read and the sources I<must> writes,
-the first relation corresponds to the reads from uninitialized
-array elements and the second relation is empty.
-The actual flow dependences can be extracted using
-C<isl_flow_foreach>.  This function will call the user-specified
-callback function C<fn> for each B<non-empty> dependence between
-a source and the sink.  The callback function is called
-with four arguments, the actual flow dependence relation
-mapping source iterations to sink iterations, a boolean that
-indicates whether it is a I<must> or I<may> dependence, a token
-identifying the source and an additional C<void *> with value
-equal to the third argument of the C<isl_flow_foreach> call.
-A dependence is marked I<must> if it originates from a I<must>
-source and if it is not followed by any I<may> sources.
-
-After finishing with an C<isl_flow>, the user should call
-C<isl_flow_free> to free all associated memory.
-
-A higher-level interface to dependence analysis is provided
-by the following function.
-
-	#include <isl/flow.h>
-
-	int isl_union_map_compute_flow(__isl_take isl_union_map *sink,
-		__isl_take isl_union_map *must_source,
-		__isl_take isl_union_map *may_source,
-		__isl_take isl_union_map *schedule,
-		__isl_give isl_union_map **must_dep,
-		__isl_give isl_union_map **may_dep,
-		__isl_give isl_union_map **must_no_source,
-		__isl_give isl_union_map **may_no_source);
-
-The arrays are identified by the tuple names of the ranges
-of the accesses.  The iteration domains by the tuple names
-of the domains of the accesses and of the schedule.
-The relative order of the iteration domains is given by the
-schedule.  The relations returned through C<must_no_source>
-and C<may_no_source> are subsets of C<sink>.
-Any of C<must_dep>, C<may_dep>, C<must_no_source>
-or C<may_no_source> may be C<NULL>, but a C<NULL> value for
-any of the other arguments is treated as an error.
-
-=head2 Scheduling
-
-B<The functionality described in this section is fairly new
-and may be subject to change.>
-
-The following function can be used to compute a schedule
-for a union of domains.  The generated schedule respects
-all C<validity> dependences.  That is, all dependence distances
-over these dependences in the scheduled space are lexicographically
-positive.  The generated schedule schedule also tries to minimize
-the dependence distances over C<proximity> dependences.
-Moreover, it tries to obtain sequences (bands) of schedule dimensions
-for groups of domains where the dependence distances have only
-non-negative values.
-The algorithm used to construct the schedule is similar to that
-of C<Pluto>.
-
-	#include <isl/schedule.h>
-	__isl_give isl_schedule *isl_union_set_compute_schedule(
-		__isl_take isl_union_set *domain,
-		__isl_take isl_union_map *validity,
-		__isl_take isl_union_map *proximity);
-	void *isl_schedule_free(__isl_take isl_schedule *sched);
-
-A mapping from the domains to the scheduled space can be obtained
-from an C<isl_schedule> using the following function.
-
-	__isl_give isl_union_map *isl_schedule_get_map(
-		__isl_keep isl_schedule *sched);
-
-A representation of the schedule can be printed using
-	 
-	__isl_give isl_printer *isl_printer_print_schedule(
-		__isl_take isl_printer *p,
-		__isl_keep isl_schedule *schedule);
-
-A representation of the schedule as a forest of bands can be obtained
-using the following function.
-
-	__isl_give isl_band_list *isl_schedule_get_band_forest(
-		__isl_keep isl_schedule *schedule);
-
-The list can be manipulated as explained in L<"Lists">.
-The bands inside the list can be copied and freed using the following
-functions.
-
-	#include <isl/band.h>
-	__isl_give isl_band *isl_band_copy(
-		__isl_keep isl_band *band);
-	void *isl_band_free(__isl_take isl_band *band);
-
-Each band contains zero or more scheduling dimensions.
-These are referred to as the members of the band.
-The section of the schedule that corresponds to the band is
-referred to as the partial schedule of the band.
-For those nodes that participate in a band, the outer scheduling
-dimensions form the prefix schedule, while the inner scheduling
-dimensions form the suffix schedule.
-That is, if we take a cut of the band forest, then the union of
-the concatenations of the prefix, partial and suffix schedules of
-each band in the cut is equal to the entire schedule (modulo
-some possible padding at the end with zero scheduling dimensions).
-The properties of a band can be inspected using the following functions.
-
-	#include <isl/band.h>
-	isl_ctx *isl_band_get_ctx(__isl_keep isl_band *band);
-
-	int isl_band_has_children(__isl_keep isl_band *band);
-	__isl_give isl_band_list *isl_band_get_children(
-		__isl_keep isl_band *band);
-
-	__isl_give isl_union_map *isl_band_get_prefix_schedule(
-		__isl_keep isl_band *band);
-	__isl_give isl_union_map *isl_band_get_partial_schedule(
-		__isl_keep isl_band *band);
-	__isl_give isl_union_map *isl_band_get_suffix_schedule(
-		__isl_keep isl_band *band);
-
-	int isl_band_n_member(__isl_keep isl_band *band);
-	int isl_band_member_is_zero_distance(
-		__isl_keep isl_band *band, int pos);
-
-Note that a scheduling dimension is considered to be ``zero
-distance'' if it does not carry any proximity dependences
-within its band.
-That is, if the dependence distances of the proximity
-dependences are all zero in that direction (for fixed
-iterations of outer bands).
-
-A representation of the band can be printed using
-
-	#include <isl/band.h>
-	__isl_give isl_printer *isl_printer_print_band(
-		__isl_take isl_printer *p,
-		__isl_keep isl_band *band);
-
-=head3 Options
-
-	#include <isl/schedule.h>
-	int isl_options_set_schedule_max_constant_term(
-		isl_ctx *ctx, int val);
-	int isl_options_get_schedule_max_constant_term(
-		isl_ctx *ctx);
-	int isl_options_set_schedule_maximize_band_depth(
-		isl_ctx *ctx, int val);
-	int isl_options_get_schedule_maximize_band_depth(
-		isl_ctx *ctx);
-	int isl_options_set_schedule_outer_zero_distance(
-		isl_ctx *ctx, int val);
-	int isl_options_get_schedule_outer_zero_distance(
-		isl_ctx *ctx);
-
-=over
-
-=item * max_constant_term
-
-This option enforces that the constant coefficients in the calculated schedule
-are not larger than the maximal constant term. This option can significantly
-increase the speed of the scheduling calculation and may also prevent fusing of
-unrelated dimensions. A value of -1 means that this option does not introduce
-bounds on the constant coefficients.
-
-=item * maximize_band_depth
-
-If this option is set, we do not split bands at the point
-where we detect splitting is necessary. Instead, we
-backtrack and split bands as early as possible. This
-reduces the number of splits and maximizes the width of
-the bands. Wider bands give more possibilities for tiling.
-
-=item * schedule_outer_zero_distance
-
-If this option is set, then we try to construct schedules
-where the outermost scheduling dimension in each band
-results in a zero dependence distance over the proximity
-dependences.

-=head2 Parametric Vertex Enumeration
-
-The parametric vertex enumeration described in this section
-is mainly intended to be used internally and by the C<barvinok>
-library.
-
-	#include <isl/vertices.h>
-	__isl_give isl_vertices *isl_basic_set_compute_vertices(
-		__isl_keep isl_basic_set *bset);
-
-The function C<isl_basic_set_compute_vertices> performs the
-actual computation of the parametric vertices and the chamber
-decomposition and store the result in an C<isl_vertices> object.
-This information can be queried by either iterating over all
-the vertices or iterating over all the chambers or cells
-and then iterating over all vertices that are active on the chamber.
-
-	int isl_vertices_foreach_vertex(
-		__isl_keep isl_vertices *vertices,
-		int (*fn)(__isl_take isl_vertex *vertex, void *user),
-		void *user);
-
-	int isl_vertices_foreach_cell(
-		__isl_keep isl_vertices *vertices,
-		int (*fn)(__isl_take isl_cell *cell, void *user),
-		void *user);
-	int isl_cell_foreach_vertex(__isl_keep isl_cell *cell,
-		int (*fn)(__isl_take isl_vertex *vertex, void *user),
-		void *user);
-
-Other operations that can be performed on an C<isl_vertices> object are
-the following.
-
-	isl_ctx *isl_vertices_get_ctx(
-		__isl_keep isl_vertices *vertices);
-	int isl_vertices_get_n_vertices(
-		__isl_keep isl_vertices *vertices);
-	void isl_vertices_free(__isl_take isl_vertices *vertices);
-
-Vertices can be inspected and destroyed using the following functions.
-
-	isl_ctx *isl_vertex_get_ctx(__isl_keep isl_vertex *vertex);
-	int isl_vertex_get_id(__isl_keep isl_vertex *vertex);
-	__isl_give isl_basic_set *isl_vertex_get_domain(
-		__isl_keep isl_vertex *vertex);
-	__isl_give isl_basic_set *isl_vertex_get_expr(
-		__isl_keep isl_vertex *vertex);
-	void isl_vertex_free(__isl_take isl_vertex *vertex);
-
-C<isl_vertex_get_expr> returns a singleton parametric set describing
-the vertex, while C<isl_vertex_get_domain> returns the activity domain
-of the vertex.
-Note that C<isl_vertex_get_domain> and C<isl_vertex_get_expr> return
-B<rational> basic sets, so they should mainly be used for inspection
-and should not be mixed with integer sets.
-
-Chambers can be inspected and destroyed using the following functions.
-
-	isl_ctx *isl_cell_get_ctx(__isl_keep isl_cell *cell);
-	__isl_give isl_basic_set *isl_cell_get_domain(
-		__isl_keep isl_cell *cell);
-	void isl_cell_free(__isl_take isl_cell *cell);
-
-=head1 Applications
-
-Although C<isl> is mainly meant to be used as a library,
-it also contains some basic applications that use some
-of the functionality of C<isl>.
-The input may be specified in either the L<isl format>
-or the L<PolyLib format>.
-
-=head2 C<isl_polyhedron_sample>
-
-C<isl_polyhedron_sample> takes a polyhedron as input and prints
-an integer element of the polyhedron, if there is any.
-The first column in the output is the denominator and is always
-equal to 1.  If the polyhedron contains no integer points,
-then a vector of length zero is printed.
-
-=head2 C<isl_pip>
-
-C<isl_pip> takes the same input as the C<example> program
-from the C<piplib> distribution, i.e., a set of constraints
-on the parameters, a line containing only -1 and finally a set
-of constraints on a parametric polyhedron.
-The coefficients of the parameters appear in the last columns
-(but before the final constant column).
-The output is the lexicographic minimum of the parametric polyhedron.
-As C<isl> currently does not have its own output format, the output
-is just a dump of the internal state.
-
-=head2 C<isl_polyhedron_minimize>
-
-C<isl_polyhedron_minimize> computes the minimum of some linear
-or affine objective function over the integer points in a polyhedron.
-If an affine objective function
-is given, then the constant should appear in the last column.
-
-=head2 C<isl_polytope_scan>
-
-Given a polytope, C<isl_polytope_scan> prints
-all integer points in the polytope.

- * Functions that return an isa structure will in general _destroy_

- * We consider seven cases in which we can replace the pair by a single

- *
- *	1. all constraints of one basic map are valid
- *		=> the other basic map is a subset and can be removed
- *
- *	2. all constraints of both basic maps are either "valid" or "cut"
- *	   and the facets corresponding to the "cut" constraints
- *	   of one of the basic maps lies entirely inside the other basic map
- *		=> the pair can be replaced by a basic map consisting
- *		   of the valid constraints in both basic maps
- *
- *	3. there is a single pair of adjacent inequalities
- *	   (all other constraints are "valid")
- *		=> the pair can be replaced by a basic map consisting
- *		   of the valid constraints in both basic maps
- *
- *	4. there is a single adjacent pair of an inequality and an equality,
- *	   the other constraints of the basic map containing the inequality are
- *	   "valid".  Moreover, if the inequality the basic map is relaxed
- *	   and then turned into an equality, then resulting facet lies
- *	   entirely inside the other basic map
- *		=> the pair can be replaced by the basic map containing
- *		   the inequality, with the inequality relaxed.
- *
- *	5. there is a single adjacent pair of an inequality and an equality,
- *	   the other constraints of the basic map containing the inequality are
- *	   "valid".  Moreover, the facets corresponding to both
- *	   the inequality and the equality can be wrapped around their
- *	   ridges to include the other basic map
- *		=> the pair can be replaced by a basic map consisting
- *		   of the valid constraints in both basic maps together
- *		   with all wrapping constraints
- *
- *	6. one of the basic maps extends beyond the other by at most one.
- *	   Moreover, the facets corresponding to the cut constraints and
- *	   the pieces of the other basic map at offset one from these cut
- *	   constraints can be wrapped around their ridges to include
- *	   the union of the two basic maps
- *		=> the pair can be replaced by a basic map consisting
- *		   of the valid constraints in both basic maps together
- *		   with all wrapping constraints
- *
- *	7. the two basic maps live in adjacent hyperplanes.  In principle
- *	   such sets can always be combined through wrapping, but we impose
- *	   that there is only one such pair, to avoid overeager coalescing.
- *
- * Throughout the computation, we maintain a collection of tableaus
- * corresponding to the basic maps.  When the basic maps are dropped
- * or combined, the tableaus are modified accordingly.

-/* Compute the convex hull of a pair of basic sets without any parameters or

- *
- * We turn this problem into the computation of a convex hull of a pair
- * _bounded_ polyhedra by "changing the direction of the homogeneous
- * dimension".  This idea is due to Matthias Koeppe.
- *
- * Consider the cones in homogeneous space that correspond to the
- * input polyhedra.  The rays of these cones are also rays of the
- * polyhedra if the coordinate that corresponds to the homogeneous
- * dimension is zero.  That is, if the inner product of the rays
- * with the homogeneous direction is zero.
- * The cones in the homogeneous space can also be considered to
- * correspond to other pairs of polyhedra by chosing a different
- * homogeneous direction.  To ensure that both of these polyhedra
- * are bounded, we need to make sure that all rays of the cones
- * correspond to vertices and not to rays.
- * Let s be a direction such that <s, r> > 0 for all rays r of both cones.
- * Then using s as a homogeneous direction, we obtain a pair of polytopes.
- * The vector s is computed in valid_direction.
- *
- * Note that we need to consider _all_ rays of the cones and not just
- * the rays that correspond to rays in the polyhedra.  If we were to
- * only consider those rays and turn them into vertices, then we
- * may inadvertently turn some vertices into rays.
- *
- * The standard homogeneous direction is the unit vector in the 0th coordinate.
- * We therefore transform the two polyhedra such that the selected
- * direction is mapped onto this standard direction and then proceed
- * with the normal computation.
- * Let S be a non-singular square matrix with s as its first row,
- * then we want to map the polyhedra to the space
- *
- *	[ y' ]     [ y ]		[ y ]          [ y' ]
- *	[ x' ] = S [ x ]	i.e.,	[ x ] = S^{-1} [ x' ]
- *
- * We take S to be the unimodular completion of s to limit the growth
- * of the coefficients in the following computations.
- *
- * Let b_i + A_i x >= 0 be the constraints of polyhedron i.
- * We first move to the homogeneous dimension
- *
- *	b_i y + A_i x >= 0		[ b_i A_i ] [ y ]    [ 0 ]
- *	    y         >= 0	or	[  1   0  ] [ x ] >= [ 0 ]
- *
- * Then we change directoin
- *
- *	[ b_i A_i ]        [ y' ]		              [ y' ]
- *	[  1   0  ] S^{-1} [ x' ] >= 0	or	[ b_i' A_i' ] [ x' ] >= 0
- *
- * Then we compute the convex hull of the polytopes b_i' + A_i' x' >= 0
- * resulting in b' + A' x' >= 0, which we then convert back
- *
- *	            [ y ]		        [ y ]
- *	[ b' A' ] S [ x ] >= 0	or	[ b A ] [ x ] >= 0
- *
- * The polyhedron b + A x >= 0 is then the convex hull of the input polyhedra.

-/* Given a set of modulo constraints
- *
- *		c + A y = 0 mod d
- *
- * this function returns an affine transformation T,
- *
- *		y = T y'
- *
- * that bijectively maps the integer vectors y' to integer
- * vectors y that satisfy the modulo constraints.
- *
- * This function is inspired by Section 2.5.3
- * of B. Meister, "Stating and Manipulating Periodicity in the Polytope
- * Model.  Applications to Program Analysis and Optimization".
- * However, the implementation only follows the algorithm of that
- * section for computing a particular solution and not for computing
- * a general homogeneous solution.  The latter is incomplete and
- * may remove some valid solutions.
- * Instead, we use an adaptation of the algorithm in Section 7 of
- * B. Meister, S. Verdoolaege, "Polynomial Approximations in the Polytope
- * Model: Bringing the Power of Quasi-Polynomials to the Masses".
- *
- * The input is given as a matrix B = [ c A ] and a vector d.
- * Each element of the vector d corresponds to a row in B.
- * The output is a lower triangular matrix.
- * If no integer vector y satisfies the given constraints then
- * a matrix with zero columns is returned.
- *
- * We first compute a particular solution y_0 to the given set of
- * modulo constraints in particular_solution.  If no such solution
- * exists, then we return a zero-columned transformation matrix.
- * Otherwise, we compute the generic solution to
- *
- *		A y = 0 mod d
- *
- * That is we want to compute G such that
- *
- *		y = G y''
- *
- * with y'' integer, describes the set of solutions.
- *
- * We first remove the common factors of each row.
- * In particular if gcd(A_i,d_i) != 1, then we divide the whole
- * row i (including d_i) by this common factor.  If afterwards gcd(A_i) != 1,
- * then we divide this row of A by the common factor, unless gcd(A_i) = 0.
- * In the later case, we simply drop the row (in both A and d).
- *
- * If there are no rows left in A, then G is the identity matrix. Otherwise,
- * for each row i, we now determine the lattice of integer vectors
- * that satisfies this row.  Let U_i be the unimodular extension of the
- * row A_i.  This unimodular extension exists because gcd(A_i) = 1.
- * The first component of
- *
- *		y' = U_i y
- *
- * needs to be a multiple of d_i.  Let y' = diag(d_i, 1, ..., 1) y''.
- * Then,
- *
- *		y = U_i^{-1} diag(d_i, 1, ..., 1) y''
- *
- * for arbitrary integer vectors y''.  That is, y belongs to the lattice
- * generated by the columns of L_i = U_i^{-1} diag(d_i, 1, ..., 1).
- * If there is only one row, then G = L_1.
- *
- * If there is more than one row left, we need to compute the intersection
- * of the lattices.  That is, we need to compute an L such that
- *
- *		L = L_i L_i'	for all i
- *
- * with L_i' some integer matrices.  Let A be constructed as follows
- *
- *		A = [ L_1^{-T} L_2^{-T} ... L_k^{-T} ]
- *
- * and computed the Hermite Normal Form of A = [ H 0 ] U
- * Then,
- *
- *		L_i^{-T} = H U_{1,i}
- *
- * or
- *
- *		H^{-T} = L_i U_{1,i}^T
- *
- * In other words G = L = H^{-T}.
- * To ensure that G is lower triangular, we compute and use its Hermite
- * normal form.
- *
- * The affine transformation matrix returned is then
- *
- *		[  1   0  ]
- *		[ y_0  G  ]
- *
- * as any y = y_0 + G y' with y' integer is a solution to the original
- * modulo constraints.

- * We first compute the lexicographically minimal or maximal element
- * in the first basic map.  This results in a partial solution "res"
- * and a subset "todo" of dom that still need to be handled.
- * We then consider each of the remaining maps in "map" and successively
- * improve both "res" and "todo".
- *
- * Let res^k and todo^k be the results after k steps and let i = k + 1.
- * Assume we are computing the lexicographical maximum.
- * We first compute the lexicographically maximal element in basic map i.
- * This results in a partial solution res_i and a subset todo_i.
- * Then we combine these results with those obtain for the first k basic maps
- * to obtain a result that is valid for the first k+1 basic maps.
- * In particular, the set where there is no solution is the set where
- * there is no solution for the first k basic maps and also no solution
- * for the ith basic map, i.e.,
- *
- *	todo^i = todo^k * todo_i
- *
- * On dom(res^k) * dom(res_i), we need to pick the larger of the two
- * solutions, arbitrarily breaking ties in favor of res^k.
- * That is, when res^k(a) >= res_i(a), we pick res^k and
- * when res^k(a) < res_i(a), we pick res_i.  (Here, ">=" and "<" denote
- * the lexicographic order.)
- * In practice, we compute
- *
- *	res^k * (res_i . "<=")
- *
- * and
- *
- *	res_i * (res^k . "<")
- *
- * Finally, we consider the symmetric difference of dom(res^k) and dom(res_i),
- * where only one of res^k and res_i provides a solution and we simply pick
- * that one, i.e.,
- *
- *	res^k * todo_i
- * and
- *	res_i * todo^k
- *
- * Note that we only compute these intersections when dom(res^k) intersects
- * dom(res_i).  Otherwise, the only effect of these intersections is to
- * potentially break up res^k and res_i into smaller pieces.
- * We want to avoid such splintering as much as possible.
- * In fact, an earlier implementation of this function would look for
- * better results in the domain of res^k and for extra results in todo^k,
- * but this would always result in a splintering according to todo^k,
- * even when the domain of basic map i is disjoint from the domains of
- * the previous basic maps.

- * such that the new e_i have a canonical representation in terms
- * of the vector x.
- * If any of the equalities involves more than one divs, then
- * we currently simply bail out.
- *
- * Let us first additionally assume that all equalities involve
- * a div.  The equalities then express modulo constraints on the
- * remaining variables and we can use "parameter compression"
- * to find a minimal set of constraints.  The result is a transformation
- *
- *	x = T(x') = x_0 + G x'
- *
- * with G a lower-triangular matrix with all elements below the diagonal
- * non-negative and smaller than the diagonal element on the same row.
- * We first normalize x_0 by making the same property hold in the affine
- * T matrix.
- * The rows i of G with a 1 on the diagonal do not impose any modulo
- * constraint and simply express x_i = x'_i.
- * For each of the remaining rows i, we introduce a div and a corresponding
- * equality.  In particular
- *
- *	g_ii e_j = x_i - g_i(x')
- *
- * where each x'_k is replaced either by x_k (if g_kk = 1) or the
- * corresponding div (if g_kk != 1).
- *
- * If there are any equalities not involving any div, then we
- * first apply a variable compression on the variables x:
- *
- *	x = C x''	x'' = C_2 x
- *
- * and perform the above parameter compression on A C instead of on A.
- * The resulting compression is then of the form
- *
- *	x'' = T(x') = x_0 + G x'
- *
- * and in constructing the new divs and the corresponding equalities,
- * we have to replace each x'', i.e., the x'_k with (g_kk = 1),
- * by the corresponding row from C_2.

- *
- * This function is a slight generalization of isl_mat_variable_compression
- * in that it allows the input to be parametric and that it allows for the
- * compression of either parameters or set variables.
- *
- * We first select the equalities of interest, that is those that involve
- * variables of type "type" and no later variables.
- * Denote those equalities as
- *
- *		-C(p) + M x = 0
- *
- * where C(p) depends on the parameters if type == isl_dim_set and
- * is a constant if type == isl_dim_param.
- *
- * First compute the (left) Hermite normal form of M,
- *
- *		M [U1 U2] = M U = H = [H1 0]
- * or
- *		              M = H Q = [H1 0] [Q1]
- *                                             [Q2]
- *
- * with U, Q unimodular, Q = U^{-1} (and H lower triangular).
- * Define the transformed variables as
- *
- *		x = [U1 U2] [ x1' ] = [U1 U2] [Q1] x
- *		            [ x2' ]           [Q2]
- *
- * The equalities then become
- *
- *		-C(p) + H1 x1' = 0   or   x1' = H1^{-1} C(p) = C'(p)
- *
- * If the denominator of the constant term does not divide the
- * the common denominator of the parametric terms, then every
- * integer point is mapped to a non-integer point and then the original set has no
- * integer solutions (since the x' are a unimodular transformation
- * of the x).  In this case, an empty morphism is returned.
- * Otherwise, the transformation is given by
- *
- *		x = U1 H1^{-1} C(p) + U2 x2'
- *
- * The inverse transformation is simply
- *
- *		x2' = Q2 x
- *
- * Both matrices are extended to map the full original space to the full
- * compressed space.

-/* Order size using quicksort.  This implementation incorporates
-   four optimizations discussed in Sedgewick:
-
-   1. Non-recursive, using an explicit stack of pointer that store the
-      next array partition to sort.  To save time, this maximum amount
-      of space required to store an array of SIZE_MAX is allocated on the
-      stack.  Assuming a 32-bit (64 bit) integer for size_t, this needs
-      only 32 * sizeof(stack_node) == 256 bytes (for 64 bit: 1024 bytes).
-      Pretty cheap, actually.
-
-   2. Chose the pivot element using a median-of-three decision tree.
-      This reduces the probability of selecting a bad pivot value and
-      eliminates certain extraneous comparisons.
-
-   3. Only quicksorts TOTAL_ELEMS / MAX_THRESH partitions, leaving
-      insertion sort to order the MAX_THRESH items within each partition.
-      This is a big win, since insertion sort is faster for small, mostly
-      sorted array segments.
-
-   4. The larger of the two sub-partitions is always pushed onto the
-      stack first, with the algorithm then concentrating on the
-      smaller partition.  This *guarantees* no more than log (total_elems)
-      stack size is needed (actually O(1) in this case)!  */

-/* Given a tableau representing a set, find and return

- *
- * We perform a depth first search
- * for an integer point, by scanning all possible values in the range
- * attained by a basis vector, where an initial basis may have been set
- * by the calling function.  Otherwise an initial basis that exploits
- * the equalities in the tableau is created.
- * tab->n_zero is currently ignored and is clobbered by this function.
- *
- * The tableau is allowed to have unbounded direction, but then
- * the calling function needs to set an initial basis, with the
- * unbounded directions last and with tab->n_unbounded set
- * to the number of unbounded directions.
- * Furthermore, the calling functions needs to add shifted copies
- * of all constraints involving unbounded directions to ensure
- * that any feasible rational value in these directions can be rounded
- * up to yield a feasible integer value.
- * In particular, let B define the given basis x' = B x
- * and let T be the inverse of B, i.e., X = T x'.
- * Let a x + c >= 0 be a constraint of the set represented by the tableau,
- * or a T x' + c >= 0 in terms of the given basis.  Assume that
- * the bounded directions have an integer value, then we can safely
- * round up the values for the unbounded directions if we make sure
- * that x' not only satisfies the original constraint, but also
- * the constraint "a T x' + c + s >= 0" with s the sum of all
- * negative values in the last n_unbounded entries of "a T".
- * The calling function therefore needs to add the constraint
- * a x + c + s >= 0.  The current function then scans the first
- * directions for an integer value and once those have been found,
- * it can compute "T ceil(B x)" to yield an integer point in the set.
- * Note that during the search, the first rows of B may be changed
- * by a basis reduction, but the last n_unbounded rows of B remain
- * unaltered and are also not mixed into the first rows.
- *
- * The search is implemented iteratively.  "level" identifies the current
- * basis vector.  "init" is true if we want the first value at the current
- * level and false if we want the next value.
- *
- * The initial basis is the identity matrix.  If the range in some direction
- * contains more than one integer value, we perform basis reduction based
- * on the value of ctx->opt->gbr
- *	- ISL_GBR_NEVER:	never perform basis reduction
- *	- ISL_GBR_ONCE:		only perform basis reduction the first
- *				time such a range is encountered
- *	- ISL_GBR_ALWAYS:	always perform basis reduction when
- *				such a range is encountered
- *
- * When ctx->opt->gbr is set to ISL_GBR_ALWAYS, then we allow the basis
- * reduction computation to return early.  That is, as soon as it
- * finds a reasonable first direction.

- * fairly easy to pick one of them.
- * If the recession cone is not full-dimensional, then we first
- * transform bset such that the bounded directions appear as
- * the first dimensions of the transformed basic set.
- * We do this by using a unimodular transformation that transforms
- * the equalities in the recession cone to equalities on the first
- * dimensions.
- *
- * The transformed set is then projected onto its bounded dimensions.
- * Note that to compute this projection, we can simply drop all constraints
- * involving any of the unbounded dimensions since these constraints
- * cannot be combined to produce a constraint on the bounded dimensions.
- * To see this, assume that there is such a combination of constraints
- * that produces a constraint on the bounded dimensions.  This means
- * that some combination of the unbounded dimensions has both an upper
- * bound and a lower bound in terms of the bounded dimensions, but then
- * this combination would be a bounded direction too and would have been
- * transformed into a bounded dimensions.
- *
- * We then compute a sample value in the bounded dimensions.
- * If no such value can be found, then the original set did not contain
- * any integer points and we are done.
- * Otherwise, we plug in the value we found in the bounded dimensions,
- * project out these bounded dimensions and end up with a set with
- * a full-dimensional recession cone.
- * A sample point in this set is computed by "rounding up" any
- * rational point in the set.
- *
- * The sample points in the bounded and unbounded dimensions are
- * then combined into a single sample point and transformed back
- * to the original space.

-/* The tableau maintains equality relations.
- * Each column and each row is associated to a variable or a constraint.
- * The "value" of an inequality constraint is the value of the corresponding
- * slack variable.
- * The "row_var" and "col_var" arrays map column and row indices
- * to indices in the "var" and "con" arrays.  The elements of these
- * arrays maintain extra information about the variables and the constraints.
- * Each row expresses the corresponding row variable as an affine expression
- * of the column variables.
- * The first two columns in the matrix contain the common denominator of
- * the row and the numerator of the constant term.
- * If "M" is set, then the third column represents the "big parameter".
- * The third (M = 0) or fourth (M = 1) column
- * in the matrix is called column 0 with respect to the col_var array.
- * The sample value of the tableau is the value that assigns zero
- * to all the column variables and the constant term of each affine
- * expression to the corresponding row variable.
- * The operations on the tableau maintain the property that the sample
- * value satisfies the non-negativity constraints (usually on the slack
- * variables).
- *
- * The big parameter represents an arbitrarily big (and divisible)
- * positive number.  If present, then the sign of a row is determined
- * lexicographically, with the sign of the big parameter coefficient
- * considered first.  The big parameter is only used while
- * solving PILP problems.
- *
- * The first n_dead column variables have their values fixed to zero.
- * The corresponding tab_vars are flagged "is_zero".
- * Some of the rows that have have zero coefficients in all but
- * the dead columns are also flagged "is_zero".
- *
- * The first n_redundant rows correspond to inequality constraints
- * that are always satisfied for any value satisfying the non-redundant
- * rows.  The corresponding tab_vars are flagged "is_redundant".
- * A row variable that is flagged "is_zero" is also flagged "is_redundant"
- * since the constraint has been reduced to 0 = 0 and is therefore always
- * satisfied.
- *
- * There are "n_var" variables in total.  The first "n_param" of these
- * are called parameters and the last "n_div" of these are called divs.
- * The basic tableau operations makes no distinction between different
- * kinds of variables.  These special variables are only used while
- * solving PILP problems.
- *
- * Dead columns and redundant rows are detected on the fly.
- * However, the basic operations do not ensure that all dead columns
- * or all redundant rows are detected.
- * isl_tab_detect_implicit_equalities and isl_tab_detect_redundant can be used
- * to perform and exhaustive search for dead columns and redundant rows.
- *
- * The samples matrix contains "n_sample" integer points that have at some
- * point been elements satisfying the tableau.  The first "n_outside"
- * of them no longer satisfy the tableau.  They are kept because they
- * can be reinstated during rollback when the constraint that cut them
- * out is removed.  These samples are only maintained for the context
- * tableau while solving PILP problems.

-/*
- * The implementation of parametric integer linear programming in this file
- * was inspired by the paper "Parametric Integer Programming" and the
- * report "Solving systems of affine (in)equalities" by Paul Feautrier
- * (and others).
- *
- * The strategy used for obtaining a feasible solution is different
- * from the one used in isl_tab.c.  In particular, in isl_tab.c,
- * upon finding a constraint that is not yet satisfied, we pivot
- * in a row that increases the constant term of the row holding the
- * constraint, making sure the sample solution remains feasible
- * for all the constraints it already satisfied.
- * Here, we always pivot in the row holding the constraint,
- * choosing a column that induces the lexicographically smallest
- * increment to the sample solution.
- *
- * By starting out from a sample value that is lexicographically
- * smaller than any integer point in the problem space, the first
- * feasible integer sample point we find will also be the lexicographically
- * smallest.  If all variables can be assumed to be non-negative,
- * then the initial sample value may be chosen equal to zero.
- * However, we will not make this assumption.  Instead, we apply
- * the "big parameter" trick.  Any variable x is then not directly
- * used in the tableau, but instead it is represented by another
- * variable x' = M + x, where M is an arbitrarily large (positive)
- * value.  x' is therefore always non-negative, whatever the value of x.
- * Taking as initial sample value x' = 0 corresponds to x = -M,
- * which is always smaller than any possible value of x.
- *
- * The big parameter trick is used in the main tableau and
- * also in the context tableau if isl_context_lex is used.
- * In this case, each tableaus has its own big parameter.
- * Before doing any real work, we check if all the parameters
- * happen to be non-negative.  If so, we drop the column corresponding
- * to M from the initial context tableau.
- * If isl_context_gbr is used, then the big parameter trick is only
- * used in the main tableau.

- *	- the parametric constant may be equal to that of another row
- *	  for which we know the sign.  This sign will be either "pos" or
- *	  "any".  If it had been "neg" then we would have pivoted before.
- *
- * If none of these cases hold, we check the value of the row for each

- * we make an initial determination of the sign of the row.
- *
- *	all zero			->	unk(nown)

- *	>0 ?	     Y      N	 Y     N
- *		    any    neg  any   neg
- *
- * There is no special sign for "zero", because we can usually treat zero
- * as either non-negative or non-positive, whatever works out best.
- * However, if the row is "critical", meaning that pivoting is impossible
- * then we don't want to limp zero with the non-positive case, because
- * then we we would lose the solution for those values of the parameters
- * where the value of the row is zero.  Instead, we treat 0 as non-negative
- * ensuring a split if the row can attain both zero and negative values.
- * The same happens when the original constraint was one that could not
- * be satisfied with equality by any integer values of the parameters.
- * In this case, we normalize the constraint, but then a value of zero
- * for the normalized constraint is actually a positive value for the
- * original constraint, so again we need to treat zero as non-negative.
- * In both these cases, we have the following decision tree instead:
- *
- *	all non-negative		->	pos
- *	all negative			->	neg
- *	both negative and non-negative	->	all
- *
- *	samples	       neg	          	       pos
- *	<0 ?			             	    Y        N

- * Pivots are performed until a feasible point is found, which is then
- * necessarily equal to the minimum, or until the tableau is found to
- * be infeasible.  Some pivots may need to be performed for only some
- * feasible values of the context tableau.  If so, the context tableau
- * is split into a part where the pivot is needed and a part where it is not.
- *
- * Whenever we enter the main loop, the main tableau is such that no
- * "obvious" pivots need to be performed on it, where "obvious" means
- * that the given row can be seen to be negative without looking at
- * the context tableau.  In particular, for non-parametric problems,
- * no pivots need to be performed on the main tableau.
- * The caller of find_solutions is responsible for making this property
- * hold prior to the first iteration of the loop, while restore_lexmin
- * is called before every other iteration.
- *
- * Inside the main loop, we first examine the signs of the rows of
- * the main tableau within the context of the context tableau.
- * If we find a row that is always non-positive for all values of
- * the parameters satisfying the context tableau and negative for at
- * least one value of the parameters, we perform the appropriate pivot
- * and start over.  An exception is the case where no pivot can be
- * performed on the row.  In this case, we require that the sign of
- * the row is negative for all values of the parameters (rather than just
- * non-positive).  This special case is handled inside row_sign, which
- * will say that the row can have any sign if it determines that it can
- * attain both negative and zero values.
- *
- * If we can't find a row that always requires a pivot, but we can find
- * one or more rows that require a pivot for some values of the parameters
- * (i.e., the row can attain both positive and negative signs), then we split
- * the context tableau into two parts, one where we force the sign to be
- * non-negative and one where we force is to be negative.
- * The non-negative part is handled by a recursive call (through find_in_pos).
- * Upon returning from this call, we continue with the negative part and
- * perform the required pivot.
- *
- * If no such rows can be found, all rows are non-negative and we have
- * found a (rational) feasible point.  If we only wanted a rational point
- * then we are done.
- * Otherwise, we check if all values of the sample point of the tableau
- * are integral for the variables.  If so, we have found the minimal
- * integral point and we are done.
- * If the sample point is not integral, then we need to make a distinction
- * based on whether the constant term is non-integral or the coefficients
- * of the parameters.  Furthermore, in order to decide how to handle
- * the non-integrality, we also need to know whether the coefficients
- * of the other columns in the tableau are integral.  This leads
- * to the following table.  The first two rows do not correspond
- * to a non-integral sample point and are only mentioned for completeness.
- *
- *	constant	parameters	other
- *
- *	int		int		int	|
- *	int		int		rat	| -> no problem
- *
- *	rat		int		int	  -> fail
- *
- *	rat		int		rat	  -> cut
- *
- *	int		rat		rat	|
- *	rat		rat		rat	| -> parametric cut
- *
- *	int		rat		int	|
- *	rat		rat		int	| -> split context
- *
- * If the parametric constant is completely integral, then there is nothing
- * to be done.  If the constant term is non-integral, but all the other
- * coefficient are integral, then there is nothing that can be done
- * and the tableau has no integral solution.
- * If, on the other hand, one or more of the other columns have rational
- * coefficients, but the parameter coefficients are all integral, then
- * we can perform a regular (non-parametric) cut.
- * Finally, if there is any parameter coefficient that is non-integral,
- * then we need to involve the context tableau.  There are two cases here.
- * If at least one other column has a rational coefficient, then we
- * can perform a parametric cut in the main tableau by adding a new
- * integer division in the context tableau.
- * If all other columns have integral coefficients, then we need to
- * enforce that the rational combination of parameters (c + \sum a_i y_i)/m
- * is always integral.  We do this by introducing an integer division
- * q = floor((c + \sum a_i y_i)/m) and stipulating that its argument should
- * always be integral in the context tableau, i.e., m q = c + \sum a_i y_i.
- * Since q is expressed in the tableau as
- *	c + \sum a_i y_i - m q >= 0
- *	-c - \sum a_i y_i + m q + m - 1 >= 0
- * it is sufficient to add the inequality
- *	-c - \sum a_i y_i + m q >= 0
- * In the part of the context where this inequality does not hold, the
- * main tableau is marked as being empty.

-# SYNOPSIS
-#
-#   AX_CC_MAXOPT
-#
-# DESCRIPTION
-#
-#   Try to turn on "good" C optimization flags for various compilers and
-#   architectures, for some definition of "good". (In our case, good for
-#   FFTW and hopefully for other scientific codes. Modify as needed.)
-#
-#   The user can override the flags by setting the CFLAGS environment
-#   variable. The user can also specify --enable-portable-binary in order to
-#   disable any optimization flags that might result in a binary that only
-#   runs on the host architecture.
-#
-#   Note also that the flags assume that ANSI C aliasing rules are followed
-#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
-#   computations can be re-ordered as needed.
-#
-#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
-#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

-# SYNOPSIS
-#
-#   AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
-#
-# DESCRIPTION
-#
-#   the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
-#   existence of an include file <stdint.h> that defines a set of typedefs,
-#   especially uint8_t,int32_t,uintptr_t. Many older installations will not
-#   provide this file, but some will have the very same definitions in
-#   <inttypes.h>. In other enviroments we can use the inet-types in
-#   <sys/types.h> which would define the typedefs int8_t and u_int8_t
-#   respectivly.
-#
-#   This macros will create a local "_stdint.h" or the headerfile given as
-#   an argument. In many cases that file will just "#include <stdint.h>" or
-#   "#include <inttypes.h>", while in other environments it will provide the
-#   set of basic 'stdint's definitions/typedefs:
-#
-#     int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
-#     int_least32_t.. int_fast32_t.. intmax_t
-#
-#   which may or may not rely on the definitions of other files, or using
-#   the AC_CHECK_SIZEOF macro to determine the actual sizeof each type.
-#
-#   if your header files require the stdint-types you will want to create an
-#   installable file mylib-int.h that all your other installable header may
-#   include. So if you have a library package named "mylib", just use
-#
-#        AX_CREATE_STDINT_H(mylib-int.h)
-#
-#   in configure.ac and go to install that very header file in Makefile.am
-#   along with the other headers (mylib.h) - and the mylib-specific headers
-#   can simply use "#include <mylib-int.h>" to obtain the stdint-types.
-#
-#   Remember, if the system already had a valid <stdint.h>, the generated
-#   file will include it directly. No need for fuzzy HAVE_STDINT_H things...
-#   (oops, GCC 4.2.x has deliberatly disabled its stdint.h for non-c99
-#   compilation and the c99-mode is not the default. Therefore this macro
-#   will not use the compiler's stdint.h - please complain to the GCC
-#   developers).

-# SYNOPSIS
-#
-#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
-#
-# DESCRIPTION
-#
-#   This macro tries to guess the "native" arch corresponding to the target
-#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
-#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
-#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
-#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
-#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
-#
-#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
-#   the flag is set to -mtune (or equivalent) so that the architecture is
-#   only used for tuning, but the instruction set used is still portable. In
-#   the latter case, the flag is set to -march (or equivalent) so that
-#   architecture-specific instructions are enabled.
-#
-#   The user can specify --with-gcc-arch=<arch> in order to override the
-#   macro's choice of architecture, or --without-gcc-arch to disable this.
-#
-#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
-#   called unless the user specified --with-gcc-arch manually.
-#
-#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
-#
-#   (The main emphasis here is on recent CPUs, on the principle that doing
-#   high-performance computing on old hardware is uncommon.)

-#   AX_GCC_X86_CPUID(OP)
-#
-# DESCRIPTION
-#
-#   On Pentium and later x86 processors, with gcc or a compiler that has a
-#   compatible syntax for inline assembly instructions, run a small program
-#   that executes the cpuid instruction with input OP. This can be used to
-#   detect the CPU type.
-#
-#   On output, the values of the eax, ebx, ecx, and edx registers are stored
-#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
-#   ax_cv_gcc_x86_cpuid_OP.
-#
-#   If the cpuid instruction fails (because you are running a
-#   cross-compiler, or because you are not using gcc, or because you are on
-#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
-#   is set to the string "unknown".
-#
-#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

-
-# serial 4 lt~obsolete.m4
-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-# ===========================================================================
-#
-# SYNOPSIS
-#
-#   AX_CC_MAXOPT
-#
-# DESCRIPTION
-#
-#   Try to turn on "good" C optimization flags for various compilers and
-#   architectures, for some definition of "good". (In our case, good for
-#   FFTW and hopefully for other scientific codes. Modify as needed.)
-#
-#   The user can override the flags by setting the CFLAGS environment
-#   variable. The user can also specify --enable-portable-binary in order to
-#   disable any optimization flags that might result in a binary that only
-#   runs on the host architecture.
-#
-#   Note also that the flags assume that ANSI C aliasing rules are followed
-#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
-#   computations can be re-ordered as needed.
-#
-#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
-#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

-# SYNOPSIS
-#
-#   AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
-#
-# DESCRIPTION
-#
-#   Try to find a compiler option that enables most reasonable warnings.
-#
-#   For the GNU CC compiler it will be -Wall (and -ansi -pedantic) The
-#   result is added to the shellvar being CFLAGS by default.
-#
-#   Currently this macro knows about GCC, Solaris C compiler, Digital Unix C
-#   compiler, C for AIX Compiler, HP-UX C compiler, IRIX C compiler, NEC
-#   SX-5 (Super-UX 10) C compiler, and Cray J90 (Unicos 10.0.0.8) C
-#   compiler.
-#
-#    - $1 shell-variable-to-add-to : CFLAGS
-#    - $2 add-value-if-not-found : nothing
-#    - $3 action-if-found : add value to shellvariable
-#    - $4 action-if-not-found : nothing

-dnl   the for-argument contains a list of options. The first part of
-dnl   these does only exist to detect the compiler - usually it is
-dnl   a global option to enable -ansi or -extrawarnings. All other
-dnl   compilers will fail about it. That was needed since a lot of
-dnl   compilers will give false positives for some option-syntax
-dnl   like -Woption or -Xoption as they think of it is a pass-through
-dnl   to later compile stages or something. The "%" is used as a
-dnl   delimimiter. A non-option comment can be given after "%%" marks
-dnl   which will be shown but not added to the respective C/CXXFLAGS.

-# SYNOPSIS
-#
-#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
-#
-# DESCRIPTION
-#
-#   This macro tries to guess the "native" arch corresponding to the target
-#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
-#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
-#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
-#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
-#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
-#
-#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
-#   the flag is set to -mtune (or equivalent) so that the architecture is
-#   only used for tuning, but the instruction set used is still portable. In
-#   the latter case, the flag is set to -march (or equivalent) so that
-#   architecture-specific instructions are enabled.
-#
-#   The user can specify --with-gcc-arch=<arch> in order to override the
-#   macro's choice of architecture, or --without-gcc-arch to disable this.
-#
-#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
-#   called unless the user specified --with-gcc-arch manually.
-#
-#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
-#
-#   (The main emphasis here is on recent CPUs, on the principle that doing
-#   high-performance computing on old hardware is uncommon.)

-# SYNOPSIS
-#
-#   AX_GCC_X86_CPUID(OP)
-#
-# DESCRIPTION
-#
-#   On Pentium and later x86 processors, with gcc or a compiler that has a
-#   compatible syntax for inline assembly instructions, run a small program
-#   that executes the cpuid instruction with input OP. This can be used to
-#   detect the CPU type.
-#
-#   On output, the values of the eax, ebx, ecx, and edx registers are stored
-#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
-#   ax_cv_gcc_x86_cpuid_OP.
-#
-#   If the cpuid instruction fails (because you are running a
-#   cross-compiler, or because you are not using gcc, or because you are on
-#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
-#   is set to the string "unknown".
-#
-#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

-*** is disabling shared libraries support.  We urge you to upgrade GNU
-*** binutils to release 2.16.91.0.3 or newer.  Another option is to modify
-*** your PATH or compiler configuration so that the native linker is

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-# lt~obsolete.m4 -- aclocal satisfying obsolete definitions.    -*-Autoconf-*-

-# serial 4 lt~obsolete.m4
-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-% To process a Texinfo manual with TeX, it's most reliable to use the
-% texi2dvi shell script that comes with the distribution.  For a simple
-% manual foo.texi, however, you can get away with this:
-%   tex foo.texi
-%   texindex foo.??
-%   tex foo.texi
-%   tex foo.texi
-%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
-% The extra TeX runs get the cross-reference information correct.
-% Sometimes one run after texindex suffices, and sometimes you need more
-% than two; texi2dvi does it as many times as necessary.

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble.  Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-%   @multitable @columnfractions .25 .3 .45
-%   @item ...
-%
-%   Numbers following @columnfractions are the percent of the total
-%   current hsize to be used for each column. You may use as many
-%   columns as desired.
-
-
-% Or use a template:
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item ...
-%   using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item first col stuff @tab second col stuff @tab third col
-%   @item
-%   first col stuff
-%   @tab
-%   second col stuff
-%   @tab
-%   third col
-%   @item first col stuff @tab second col stuff
-%   @tab Many paragraphs of text may be used in any column.
-%
-%         They will wrap at the width determined by the template.
-%   @item@tab@tab This will be in third column.
-%   @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-%                                                            to baseline.

-\`configure' configures osl 0.8.1 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]
-  --libexecdir=DIR        program executables [EPREFIX/libexec]

-  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
-  --libdir=DIR            object code libraries [EPREFIX/lib]
-  --includedir=DIR        C header files [PREFIX/include]
-  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
-  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]

-  --with-gmp-include=DIR  DIR where gmp.h is installed
-  --with-gmp-library=DIR  DIR where the gmp library is installed
-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-1 Introduction
-**************
-
-OpenScop is an open specification that defines a file format and a set
-of data structures to represent a _static control part_ (SCoP for
-short), i.e., a program part that can be represented in the _polyhedral
-model_.  The goal of OpenScop is to provide a common interface to
-various polyhedral compilation tools in order to simplify their
-interaction.
-
-   Designing a single format for tools that have different purposes
-(e.g., as different as code generation and data dependence analysis) may
-sound strange at first. However we could observe that most available
-polyhedral compilation tools during the last decade were manipulating
-more or less the same kind of data (polyhedra, affine functions...) and
-were actually sharing a part of their input (e.g., iteration domains and
-context concepts are nearly everywhere). We could also observe that
-those tools may rely on different internal representations, mostly
-based on one of the major polyhedral libraries (e.g., Polylib, PPL or
-isl), and this representation may change over time (e.g., when
-switching to a more convenient polyhedral library).  The OpenScop aim
-is to provide a stable, unified format that offers a durable guarantee
-that a tool can use an output or provide an input to another tool
-without breaking a tool chain because of some internal changes in one
-element of the chain. The other promise of OpenScop is the ability to
-assemble or replace the basic blocks of a polyhedral compilation
-framework at no, or at least low engineering cost.
-
-   The policy that drives OpenScop can be summarized by these three
-rules:
-   * Embed the _minimum_ information to build a complete polyhedral
-       compilation framework in the so-called _core part_        (to
-     avoid as much as possible empty or useless information        for
-     each tool).
-
-   * Provide a _very stable_ core part (so users have some
-     guarantee that they will not need to update their tool
-     because of frequent specification evolution),
-
-   * Provide a _very flexible_ extension part (so it can also        be
-     used to test wild new ideas).
-
-Another, more technical, rule may be added:
-   * Avoid any need for external library or tool to support it
-     (i.e., it's not XML or YAML or anything like that).
-
-   The success of OpenScop in meeting its goals totally depends on its
-acceptance by the tool developers (that have to support it in their
-tools).  To help them, we provide an example implementation: the
-OpenScop Library.  This library (and in particular its API) is not part
-of the OpenScop specification (which includes only the file format and
-the set of data structures). It is licensed under the 3-clause BSD
-license so developers may feel free to use it in their code (either by
-linking it or copy-pasting its code). This document also describes this
-library briefly (readers are invited to read at its technical
-documentation).  The current version of the OpenScop Library is still
-under evaluation, and there is no guarantee that the upward
-compatibility will be respected, even if we do think so. A lot of
-reports are necessary to freeze the library API. Thus you are very
-welcome and encouraged to send reports on bugs, wishes, critics,
-comments, suggestions or (please!) successful experiences to the
-OpenScop mailing list <openscop-development@googlegroups.com>.
-
-   This document is organized as follows. First, we provide some
-background on the polyhedral model and how it is used to represent and
-to manipulate programs (*note Polyhedral Representation::). Next, we
-describe the OpenScop specification, from the file format (*note
-OpenScop File Format Specification::) to the data structures and the
-OpenScop Library API (*note OpenScop Data Structure Specification::).
-Finally we will detail how to install the OpenScop Library (*note
-Installation::).

-2 Polyhedral Representation of Programs
-***************************************
-
-If you are reading at the OpenScop documentation, you probably don't
-need any explanation about the polyhedral model. It is unlikely that
-someone will read this paper by mistake. However some vicious advisor
-may ask their poor engineers/interns/students to work for the very
-first time on this exciting topic. Most papers on polyhedral
-compilation are hard to read. Despite my efforts, mine are no exception
-according to some reviewers. Hence I give there a new try to provide a
-comprehensive explanation of the polyhedral model without the size and
-style limits of a classical research paper.
-
-   Be aware that to be able to understand the polyhedral model, there

-2.1 Motivation: Program Transformations
-=======================================
-
-A direct translation of high level programs written, e.g., in C, to
-assembly then to object code is likely to produce (very) inefficient
-applications.  Architectures are quite complex, including several
-levels of cache memory, many cores, deep pipelines, various number of
-functional units, of registers etc.  The list of such "architectural
-features" is growing with each new generation of processors.  To
-achieve the best performance, the object program must use these
-features in a smart way.  Programmers use high level languages for
-productivity and portability: typically they do not have to take care
-of the target architecture but to ensure they write programs which
-produce the right output. Hence, the problem of mapping the program to
-the target architecture in the most efficient way is left to the
-compiler.
-
-   The compiler may see a high level program as a specification _of an
-output_. The program is a list of instructions to be executed to
-produce the output. As long as the output is guaranteed to be as the
-programmer specified in his code, the compiler is free to modify the
-program.  For instance, let us imagine we are working on an
-architecture with only three registers and we consider the following
-statements written by a programmer:
-
-     x = a + b;
-     y = c + d;
-     z = a * b;
-
-   It is easy to see that we can reorder the three statements in any
-way without modifying the semantics (no statement reads or writes a
-variable that another statement writes). Because of the lack of
-registers, the solutions such that the first and the third statements
-are one after the other are better because `a' and `b' will be put in
-the processor registers by one statement and can be reused directly by
-the other one without reading from memory (this is called a _data
-locality improving_ transformation). Hence a better statement order is,
-e.g.:
-
-     x = a + b;
-     z = a * b; // a and b are still in processor registers
-     y = c + d;
-
-   We can also notice that it is possible to run the three statements in
-parallel (possibly on different processors). The programmer may
-explicit this in a way the compiler and/or the architecture is able to
-understand. For instance, we can use OpenMP to describe parallelism
-(this is called a _parallelizing_ transformation):
-
-     #pragma omp parallel sections
-     {
-        #pragma omp section
-        {
-          x = a + b;
-        }
-        #pragma omp section
-        {
-          y = c + d;
-        }
-        #pragma omp section
-        {
-          z = a * b;
-        }
-     }
-
-   However, the right way to optimize this program is probably a
-tradeoff between these two techniques. This is true if, e.g., the target
-architecture has some limitations to run too many operations in
-parallel, or, like in our case, when some data may be reused by some
-processors.  Hence, the best optimization for our small example is
-probably the following:
-
-     #pragma omp parallel sections
-     {
-        #pragma omp section
-        {
-          x = a + b;
-          z = a * b;
-        }
-        #pragma omp section
-        {
-          y = c + d;
-        }
-     }
-
-   This example is quite trivial because the statements are executed
-only once. The real sport begins when we have to deal with loops, as we
-will see momentarily. However, polyhedral compilation framework users
-have to be conscious that we _need_ to transform programs to achieve
-the best performance and that the best transformation  that has to be
-discovered (at the price of many, many efforts) and performed may be
-quite complex. Hence the need of powerful model and tools.

-2.2 Thinking in Polyhedra
-=========================
-
-Since the very first compilers, the internal representation of programs
-is the _Abstract Syntax Tree_, or AST. In such representation, each
-statement appears only once even if it is executed many times (e.g.,
-when it is enclosed inside a loop). This is a limitation for finding
-and applying complex transformations:
-   * It limits program analysis power. For instance if a statement
-     _depends_ on another statement (i.e., they access the same
-     memory location and at least one of these accesses is a write),
-       we will consider both statements as unique entities while the
-       dependence relation may involve only few statement executions.
-
-   * It limits program transformation power. Loop transformations
-     operate on statement executions. For instance, because they
-     consider all statement executions at the same time, present day
-       production compilers are not able to achieve loop fusion
-     (that tries to merge the loop bodies of two loops) if the loop
-     bounds       of the two loops do not match (yes, that's
-     ridiculous).
-
-   * It limits program manipulation flexibility.        Trees are very
-     rigid data structures that are not easy to manipulate.
-     Program transformation may require very complex transformations
-     that will       imply deep modifications of the control flow.
-
-   The Polyhedral Model is a convenient alternative representation which
-combines analysis power, expressiveness and high flexibility. The
-drawback is it breaks the classical structure of programs that every
-programmer is familiar with. It requires some (real) efforts to be
-smoothly manipulated, but it definitely worth it. It is based on three
-main concepts, _iteration domain_,  _scattering function_ and _access
-function_ that are described in depth in the following sections.
-
-   A program part that can be represented using the Polyhedral Model is
-called a *Static Control Part* or *SCoP* for short.

-
-2.2.1 Iteration Domain
-----------------------
-
-The key aspect of the polyhedral model is to consider _statement
-instances_. A statement instance is _one_ execution of a statement.  A
-statement outside a loop has only one instance while those inside loops
-may have many.  Let us consider the following code with two statements
-`S1' and `S2':
-
-     pi = 3.14;               // S1
-     for (i = 0; i < 5; i++)
-       A[i] = pi;             // S2
-
-   The list of statement instances is the following (we just have to
-fully unroll the loop):
-
-     pi = 3.14;
-     A[0] = pi;
-     A[1] = pi;
-     A[2] = pi;
-     A[3] = pi;
-     A[4] = pi;
-
-   Each instance of a statement which is enclosed inside a loop may be
-referred thanks to its outer loop counters (or _iterators_). In the
-polyhedral model we consider statements as functions of the outer loop
-counters that may produce statement instances: instead of simply
-"`S2'", we use preferably the notation `S2(i)'.  For instance we
-denote the statement instance `A[3] = pi;' of the previous example as
-`S2(3)'. This means _instance of statement `S2' for_ `i = 3'.  If a
-statement `S3' is enclosed inside two loops of iterators `i' (outermost
-loop) and `j' (innermost loop), we would denote it `S3(i,j)', and so on
-with more enclosing loops.
-
-   The ordered list of iterators (ordered from the outermost iterator
-to the innermost iterator) is called the *iteration vector*. For
-instance the iteration vector for `S3' is `(i,j)', for `S2' it is
-`(i)', and for `S1' it is empty since it has no enclosing loop: `()'. A
-more precise reading at the notation `S2(3)' would show that it denotes
-the instance of statement `S2' for the iteration vector `(2)'.
-
-   Obviously, dealing with statement instances does not mean we have to
-unroll all loops. First because there would be probably too many
-instances to deal with, and second because we probably just do not know
-how many instances there are.  For instance in the following loop it is
-impossible to know (at compile time) how many times the statement `S3'
-will be executed:
-
-     for (i = 2; i <= N; i++)
-       for (j = 2; j <= N; j++)
-         A[i] = pi;             // S3
-
-Such a loop is said to be _parametric_: it depends on (at least) a
-value called a _parameter_ which is not modified during the execution
-of the whole loop, but is unknown at compile time.  Here, the only
-parameter is `N'.
-
-   A compact way to represent all the instances of a given statement is
-to consider the set of all possible values of its iteration vector.
-This set is called the *iteration domain*. It can be conveniently
-described thanks to all the constraints on the various iterators the
-statement depends on. For instance, let us consider the statement `S3'
-of the previous program. The iteration domain is the set of iteration
-vectors `(i,j)'. Because of the parameter, we are not able to achieve a
-precise list of all possible values. It would look like this:
-
-     (2,2)  (2,3)  (2,4)  ...  (2,N)
-     (3,2)  (3,3)  (3,4)  ...  (3,N)
-     ...    ...    ...    ...  ...
-     (N,2)  (N,3)  (N,4)  ...  (N,N)
-
-A better way is to say it is the set of iteration vectors `(i,j)' such
-that `i' is an integer greater or equal than 2 and lower or equal than
-`N', and `j' is an integer greater or equal than 2 and lower or equal
-than `N'. This may be written in the following mathematical form:
-
-     D_S3 =  {(i,j) in Z^2 | 2 <= i <= N && 2 <= j <= N }
-
-It is easy to see that this iteration domain is a part of the
-2-dimensional space
-     Z^2.
-We often use in our research papers a graphical representation that
-gives a better view of this subspace:
-
-
-  | |      |
-  | |      |
-N-+-********--j<=N
-  | ********
-  | ********
-  | ********
-2-+-********--j>=2
-  | |      |
-0-+-+------+--->i
-  | |      |
-  0 2      N
-"
-
-Here, the iteration domain is specified thanks to a set of constraints.
-When those constraints are affine and depend only on the outer loop
-counters and some parameters, the set of constraints defines a
-_polyhedron_ (more precisely this is a _Z-polyhedron_, but we use
-_polyhedron_ for short).  Hence the _polyhedral model_!
-
-   To manipulate a set of affine constraints easily, we rely on a matrix
-representation. To write it, we use the _homogeneous_ iteration vector:
-it is simply the iteration vector with some additional dimensions to
-represent the parameters and the constant.  For instance for the
-statement `S3', the iteration vector in homogeneous coordinates is `(i,
-j, N, 1)' (we will now call it _iteration vector_ directly for short).
-Then we write all the constraints as affine inequalities of the form
-_affine constraint_ ` >= 0'.  For instance for the statement `S3' the
-set of constraints is:
-
-         i - 2 >= 0
-        -i + N >= 0
-         j - 2 >= 0
-        -j + N >= 0
-
-Lastly, we translate the constraint system to the form *domain matrix*`
-* '_iteration vector_` >= 0':
-
-     [  1  0  0 -2 ]   [ i ]    [ 0 ]
-     [ -1  0  1  0 ]   [ j ]    [ 0 ]
-     [  0  1  0 -2 ] * [ N ] >= [ 0 ]
-     [  0 -1  1  0 ]   [ 1 ]    [ 0 ]
-
-*The domain matrix will be used in all our tools to provide the
-information on the iteration domain of a given statement (the iteration
-vector is in general an implicit information).*

-
-2.2.2 Scattering Function
--------------------------
-
-There is no ordering information inside the iteration domain: it only
-describes the set of statement instances but *not* the order in which
-they have to be executed relatively to each other. In the past the
-lexicographic order of the iteration domain was considered, this is no
-more true (especially when using CLooG). If we do not provide any
-ordering information, this means that the statement instances may be
-executed in any order (this is useful, e.g., to specify parallelism).
-However, some statement instances may depend on some others and it may
-be critical to enforce a given order (or non-order). Hence we need
-another information.
-
-   We call _scattering_ any kind of ordering information in the
-polyhedral model. There exists many kind of ordering, such as
-_allocation_, _scheduling_, _chunking_ etc. They are all expressed in
-the same way, i.e., using _logical stamps_, but they may have different
-semantics.
-
-   In the case of *scheduling*, the logical stamps are logical dates
-that express at which date a statement instance has to be executed. For
-instance, let us consider the following three statements:
-
-     x = a + b;   // S1
-     y = c + d;   // S2
-     z = a * b;   // S3
-
-The scheduling of a statement `S' is typically denoted by T_S.  Let us
-consider the following logical dates for each statement:
-
-     T_S1 = 1
-     T_S2 = 2
-     T_S3 = 3
-
-It means that statement `S3' has to be executed at logical date `1',
-statement `S1' has to be executed at logical date `2' and statement
-`S2' has to be executed at logical date `3'. The target code has to
-respect this scheduling (the order of the logical dates), hence it
-would look like the following where the variable `t' denotes the time:
-
-     t = 1;
-     z = a * b;   // S3
-     t = 2;
-     x = a + b;   // S1
-     t = 3;
-     y = c + d;   // S2
-
-When some statements share the same logical date, this means that, once
-the program reaches this logical date, the two statements can be
-executed in any order, or better, in parallel. For instance let us
-consider the following scheduling:
-
-     T_S1 = 1
-     T_S2 = 2
-     T_S3 = 1
-
-Statements `S1' and `S3' have the same logical date, moreover, `S2' has
-a greater logical date than `S1' and `S3'.  Hence the target code would
-be:
-
-     t = 1;
-     #pragma omp parallel sections
-     {
-        #pragma omp section
-        {
-          x = a + b;   // S1
-        }
-        #pragma omp section
-        {
-          z = a * b;   // S3
-        }
-     }
-     t = 2;
-     y = c + d;        // S2
-
-   Logical dates may be multidimensional, as clocks: the first dimension
-may correspond to days (most significant), the next one to hours (less
-significant), the third to minutes and so on. For instance we can
-consider the following multidimensional schedules for our example:
-
-     T_S1 = (1,1)
-     T_S2 = (2,1)
-     T_S3 = (1,2)
-
-It is not very hard to decypher the meaning of such scheduling.
-Because of the first dimension, statements `S1' and `S3' will be
-executed before statement `S2' (`S1' and `S3' are executed at day 1,
-while `S2' is executed at day 2). The second dimension is not really
-useful there for `S2' because it is the only statement executed at day
-2. Nevertheless it allows to order `S1' and `S3' relatively to each
-other since `S1' is executed at hour 1 of day 1 while `S3' is executed
-at hour 2 of day 1.  The corresponding target code is the following,
-with some additional time variables for a better view of the ordering
-(`t1' corresponds to the first time dimension, `t2' to the second one):
-
-     t1 = 1;
-     t2 = 1;
-     x = a + b;   // S1
-     t2 = 2;
-     z = a * b;   // S3
-     t1 = 2;
-     t2 = 1;
-     y = c + d;   // S2
-
-   In the case of *allocation* (in the literature we can find some
-papers calling it _placement_), the logical stamp is a processor number
-expressing on which processor a statement instance has to be executed.
-Typically, allocations are written in the same way as scheduling.
-Here, we denote it P_S for a statement `S'.  For instance, let us
-consider the following allocation:
-
-     P_S1 = 1
-     P_S2 = 2
-     P_S3 = 1
-
-The corresponding target code has to take into account that both
-statements `S1' and `S3' have to be executed on the same processor
-(they have the same logical number 1) and that statement `S2' has to be
-executed on another processor (logical number 2). A possible target code
-is the following:
-
-     #pragma omp parallel sections
-     {
-        #pragma omp section
-        {
-          // Logical processor 1
-          x = a + b;   // S1
-          z = a * b;   // S3
-        }
-        #pragma omp section
-        {
-          // Logical processor 2
-          y = c + d;   // S2
-        }
-     }
-
-We can note that no order has been specified for the statements `S1'
-and `S3' that are executed on the same processor.  Hence any order is
-satisfying. For sake of flexibility, it is usual to build a scattering
-whose various dimensions do not have the same semantics. A typical
-construction is _space/time mapping_ where the first `n' dimensions are
-devoted to allocation, then the last `m' dimensions are devoted to
-scheduling. Typically, space/time mapping is written in the same way as
-scheduling.  Here we denote it M_S for a statement `S'.  For instance,
-let us consider the following space/time mapping for our example where
-one dimension is devoted to mapping and one dimension is devoted to
-scheduling:
-
-     M_S1 = (1,2)
-     M_S2 = (2,1)
-     M_S3 = (1,1)
-
-Here we have the same first dimension as the previous example, thus the
-allocation of the statements to processors is the same. The second
-dimension precises on a given processor at which logical date a
-statement instance has to be executed. Here, the statement `S1' is
-executed at day 2 on processor 1 while the statement `S3' is executed
-at day 1 onto the same processor. It follows this space/time mapping
-corresponds to the following target code (we added an additional
-variable to represent the local logical clocks):
-
-     #pragma omp parallel sections
-     {
-        #pragma omp section
-        {
-          // Logical processor 1
-          t = 1;
-          z = a * b;   // S3
-          t = 2;
-          x = a + b;   // S1
-        }
-        #pragma omp section
-        {
-          // Logical processor 2
-          t = 1;
-          y = c + d;   // S2
-        }
-     }
-
-   For the same reason as discussed for iteration domains (*note
-Iteration Domain::), it is not possible to define a scattering for each
-statement instance, especially if the statement belongs to a (possibly
-parametric) loop. The iteration vector fully defines an instance of a
-given statement. Thus, a practical way to provide a scattering for each
-instance of a given statement is to use a _function_ that depends on
-the iteration vector. In this way the function may associate to each
-iteration vector a different scattering. We call these functions
-*scattering functions*. Scattering functions are _affine_ functions of
-the outer loop counter and the global parameters.  For instance, let us
-consider the following source code:
-
-     for (i = 2; i <= 4; i++)
-       for (j = 2; j <= 4; j++)
-         P[i+j] += A[i] + B[j]; // S4
-
-The iteration domain of the statement `S4' is:
-
-     D_S4=  {(i,j) in Z^2 | 2 <= i <= 4 && 2 <= j <= 4 }.
-
-If you are still not comfortable with the mathematical notation, it
-corresponds to the following graphical representation:
-
-
-  | | i<=4
-  | | |
-4-+-***--j<=4
-  | ***
-2-+-***--j>=2
-  | | |
-0-+-+-+--->i
-  | | |
-  0 2 4
-"
-
-The list of the statement instances of `S4' (the integer points of its
-iteration domain) corresponds to the following iteration vectors:
-
-     iteration vector
-          (2,2)
-          (2,3)
-          (2,4)
-          (3,2)
-          (3,3)
-          (3,4)
-          (4,2)
-          (4,3)
-          (4,4)
-
-Let us suppose we want to schedule the instances of the statement `S4'
-(the integer points of its iteration domain) using the following
-scheduling function:
-
-     T_S4(i,j) = (j+2,3*i+j)
-
-We only need to apply the function to each iteration vector to find the
-logical date of each instance:
-
-     iteration vector       logical date
-          (2,2)       -->       (4,8)
-          (2,3)       -->       (5,9)
-          (2,4)       -->       (6,10)
-          (3,2)       -->       (4,11)
-          (3,3)       -->       (5,12)
-          (3,4)       -->       (6,13)
-          (4,2)       -->       (4,14)
-          (4,3)       -->       (5,15)
-          (4,4)       -->       (6,16)
-
-   The polyhedral model users do not have to take care about the
-generation of a target code that respects the scattering: the CLooG(1)
-tool is there to solve the problem quite easily. For the previous
-example, the target code would be the following (`t1' and `t2'
-correspond to the two dimensions of the logical date, the reader may
-take care that this code actually implements the scattering function):
-
-     for (t1 = 4; t1 <= 6; t1++) {
-       for (t2 = t1+4; t2 <= t1+10; t2++) {
-         if ((-t1+t2+2)%3 == 0) {
-           i = (-t1+t2+2)/3 ;
-           j = t1-2 ;
-           P[i+j] += A[i] + B[j]; // S4
-         }
-       }
-     }
-
-   Obviously with such a twisted scheduling, it is hard to see the
-"meaning" of the transformation. To name any kind of program
-transformation as a magic spell ("tile", "fuse", "skew"...) is an old
-bad habit which is not relevant anymore in the polyhedral model: a
-scheduling may be an arbitrary complex sequence of basic-old-good
-transformations. Nevertheless it is most of the time quite easy to
-translate well known transformations to schedules.  For instance, let
-us consider this new scheduling function:
-
-     T_S4(i,j) = (j,i)
-
-Using CLooG, we can generate the target code:
-
-     for (t1 = 2; t1 <= 4; t1++) {
-       for (t2 = 2; t2 <= 4; t2++) {
-         i = t2;
-         j = t1;
-         P[i+j] += A[i] + B[j]; // S4
-       }
-     }
-
-It is easy to see (and analyze) that it corresponds to a classical
-_loop interchange_ transformation.
-
-   A very useful example of multi-dimensional scattering functions is
-the *scheduling of the original program*.  The method to compute it is
-quite simple (*note Fea92::). The idea is to build an abstract syntax
-tree of the program and to read the scheduling for each statement. For
-instance, let us consider the following implementation of a Cholesky
-factorization:
-
-     /* A Cholesky factorization kernel. */
-     for (i=1;i<=N;i++) {
-       for (j=1;j<=i-1;j++) {
-         a[i][i] -= a[i][j] ;           // S1
-       }
-       a[i][i] = sqrt(a[i][i]) ;        // S2
-       for (j=i+1;j<=N;j++) {
-         for (k=1;k<=i-1;k++) {
-           a[j][i] -= a[j][k]*a[i][k] ; // S3
-         }
-         a[j][i] /= a[i][i] ;           // S4
-         }
-       }
-     }
-
-The corresponding abstract syntax tree is shown in the following
-figure. It directly gives the scattering functions (schedules) for all
-the statements of the program (just follow the paths).

-     T_S4(i,j)   = (0,i,2,j,1)
-
-These schedules depend on the iterators and give for each instance of
-each statement a unique execution date. Using such scattering functions
-allows CLooG to re-generate the input code.
-
-To easily manipulate the scattering function of any statement `S', we
-translate it to the matrix form: T_S(_iteration vector_) ` =
-'*scattering matrix*` * '_iteration vector_.  For instance let us
-consider again our previous example T_S4(i,j) = (j+2,3*i+j).  We write
-it in the following way:
-          [ i ]    [  0  1  2 ]   [ i ]
-     T_S4([ j ]) = [  3  1  0 ] * [ j ]
-          [ 1 ]                   [ 1 ]
-
-*The scattering matrix will be used in all our tools to provide the
-information on the scattering of a given statement (the iteration
-vector is in general an implicit information).*

-2.2.3 Access Function
----------------------
-
-Before applying any transformation, it is essential to deeply analyze
-both the original program and the transformation to ensure the
-transformation does not imply any modification of the original program
-semantics. In the polyhedral model, we are able to achieve an exact
-analysis when all the memory accesses are made through arrays (note
-that variables are a particular case of arrays since they are simply
-arrays with only one memory location) with affine subscripts that depend
-on outer loop counters and global parameters (note that _subscripts_
-are sometimes called _index_ or _accesses_ in the literature).
-
-   For instance let us consider the array access `A[2*i+j][j][i+N]'. It
-has three dimensions, each subscript dimension is an affine form of
-some outer loop iterarors (`i' and `j') and global parameters (`N')
-hence it corresponds to an acceptable array access to be analyzed in the
-polyhedral model.
-
-   Each array access can target a different memory cell depending on the
-statement instance, i.e., depending on the iteration vector.  Thus we
-use access functions (or subscript functions, or index functions, as you
-prefer to call it) depending on the iteration vector to describe an
-array access. In our example, the access function would be written
-F_A(i, j) = (2*i+j, j, i+N).
-
-To easily manipulate the access function of any array `A', we translate
-it to the matrix form: F_A(_iteration vector_) ` = '*access matrix*` *
-'_iteration vector_.  For instance let us consider again our previous
-example. We would write it in the following way:
-         [ i ]    [  2  1  0  0 ]   [ i ]
-     F_A([ j ]) = [  0  1  0  0 ] * [ j ]
-         [ N ]    [  1  0  1  0 ]   [ N ]
-         [ 1 ]                      [ 1 ]
-
-*The access matrix will be used in all our tools to provide the
-information on the access of a given statement (the iteration vector is
-in general an implicit information).*

-2.3 What's Next?
-================
-
-OK, now you have an idea about how we do represent a program part in the
-polyhedral model. You know the three main concepts, namely: domain,
-scattering and access. What can you do with this?! Well, pretty much
-anything related to code restructuring! The core idea will be to rely
-on the mathematical representation to extract useful information about
-your code (data reuse, parallelism...) and to generate a scattering to
-benefit from the properties you analysed.  However, OpenScop's
-documentation is not the right place to learn at this (OpenScop is all
-about representation, not about manipulation). Probably it is the right
-time for you to have a look at:
-   * PoCC `http://pocc.sourceforge.net'
-
-   * Pluto `http://pluto-compiler.sourceforge.net'

-3 OpenScop Specification
-************************
-
-OpenScop provides an explicit polyhedral representation of a static
-control part. It has been designed by various polyhedral compilation
-tool writers from various institutions. It builds on previous popular
-polyhedral file and data structure formats (such as _.cloog_ and CLooG
-data structures) to provide a unique, extensible format to most
-polyhedral compilation tools. It is composed of two parts. The first
-part, the so-called _core part_, is devoted to the polyhedral
-representation of a SCoP.  It contains what is strictly necessary to
-build a complete source-to-source framework in the polyhedral model and
-to output a semantically equivalent code for the SCoP, from analysis to
-code generation.  The second part of the format, the so-called
-_extension part_, contains extensions to provide additional
-informations to some tools.

-
-3.1 Preliminary Example
-=======================
-
-OpenScop is a specification for representing static control program
-parts in the polyhedral model. Thus, we can translate some code parts
-to an equivalent OpenScop representation. As an example, let us
-consider the following matrix-multiply kernel:
-
-     #pragma scop
-     if (N > 0) {
-       for (i = 0; i < N; i++) {
-         for (j = 0; j < N; j++) {
-           C[i][j] = 0.0;
-           for (k = 0; k < N; k++)
-             C[i][j] = C[i][j] + A[i][k] * B[k][j];
-         }
-       }
-     }
-
-   The Clan(1) tool may be used to translate this code part to an
-OpenScop representation automatically. The `#pragma scop' is used here
-for Clan, but some other tool may not need it. Here is the result of the
-translation to an OpenScop textual representation.
-
-
-                             *DON'T PANIC*
-
-Explanations will follow and it is not as cryptic as it seems to be !

-
-   The `Context' and the `Statements' parts compose the _core part_,
-i.e., what is strictly necessary to build a complete source to source
-framework based on OpenSCop:
-   * `Context' represents the global information of the SCoP. It
-     consists on the target language, the global constraints on the
-       parameters and optionally the parameter information which may be
-     necessary        for the code generation process. The constraints
-     on the parameters        are represented as a relation (*note
-     Context Domain Relation::).         The parameter information is
-     optional. It is preceded by a        boolean which precises
-     whether it is provided or not.         It is a generic information
-     (*note Generics::), a `strings'        (*note Strings Generic::)
-     for instance.
-
-   * `Statements' represents the information about the statements.
-       `Nb_statements' is the number of statements in the SCoP,
-     i.e. the number of `Statement' items in the `Statement_list'.
-       `Statement' represents the information on a given statement.
-        To each statement is associated a list of relations and,
-     optionaly, a body. The list of relations may include        one
-     iteration domain (*note Iteration Domain Relation::),        one
-     scattering relation (*note Scattering Relation::)        and
-     several access relations (*note Access Relation::).         There
-     is no mandatory ordering, but for consistency reason it would
-      be much appreciated that iteration domain comes first (if present)
-           then scattering (if present), then accesses (if present).
-         The statement body is an optional information. It is preceded

-
-   _Relations_ are the essence of the OpenScop format and contain the
-"polyhedral" information. They are used to describe either an iteration
-domain, or a context domain, or a scattering or a memory access.
-
-   We use the relation term as a shortcut to denote a union of convex
-relations, each element of the union being described by a set of
-constraints in an extended PolyLib format (*note Wil93::).  The number
-of elements in the union is given by an integer on the first line,
-optionally followed by a comment starting with `#'.  This number of
-elements can be omitted when there is only one element.  Each element
-in the union has the following syntax:
-
-  1. Some optional comment lines beginning with `#'.
-
-  2. A line with the type of the relation, possibly followed by
-     comments.        The type can be one of the following:
-        * `UNDEFINED': generic relation,
-
-        * `CONTEXT': for context information,
-
-        * `DOMAIN': for iteration domains,
-
-        * `SCATTERING': for scattering relation,
-
-        * `READ': for read accesses,
-
-        * `WRITE': for write accesses,
-
-        * `MAY_WRITE': for may-write accesses,
-
-  3. A line with 6 numbers, possibly followed by comments:
-       1. the number of rows of the constraint matrix,
-
-       2. the number of columns of the constraint matrix,
-
-       3. the number of _output dimensions_,
-
-       4. the number of _input dimension_,
-
-       5. the number of _local dimensions_             (existentially
-          quantified dimensions),
-
-       6. the number of _parameters_.
-                The sum of the last four numbers should be equal to the
-     number of columns       minus two. The remaining two columns are
-     the equality/inequality       indicator and the constant term. The
-     number of parameters should be the       same for all relations in
-     the entire OpenScop file or data structure.
-
-  4. The constraint rows. Each row corresponds to a constraint the
-     relation has to satisfy. Each row must be on a single line and is
-     possibly       followed by comments. The constraint is an equality
-     p(x) = 0 if the       first element is 0, an inequality  p(x) \geq
-     0 if the first element       is 1. The next elements are the
-     coefficients of the output dimensions,       followed by
-     coefficients of the input dimensions, the existentially
-     quantified dimensions and finally the parameters.        The last
-     element is the constant term.
-
-   This representation is the basis for several purposes. Examples for
-iteration domains (*note Iteration Domain Relation::), context domains

-Scattering Relation::) and access relations (*note Access Relation::)

-3.2.1.1 Iteration Domain Relation
-.................................
-
-Iteration domain represents the set of instances of the corresponding
-statement.  OpenScop iteration domains are represented as relations
-with the following conventions:
-   * the type is `DOMAIN',
-
-   * there is 0 input dimension,
-
-   * loop iterators correspond to output dimensions.
-
-For instance, assuming that `i', `j' and `k' are the loop iterators and
-`M' and `N' are the parameters, the domain defined by the following
-constraints :
-
-        -i + M >= 0
-        -j + N >= 0
-     i + j - k >= 0
-
-can be written in the input file as follows:
-
-     # This is an iteration domain
-     DOMAIN
-     1 # Number of relations in the union
-     3 7 3 0 0 2                  # 3 rows, 7 cols: 3 output dims and 2 params
-     # e/i| i   j   k | M   N | 1
-        1  -1   0   0   1   0   0 #    -i + M >= 0
-        1   0  -1   0   0   1   0 #    -j + N >= 0
-        1   1   1  -1   0   0   0 # i + j - k >= 0
-
-Equivalently, it can be written in the following way as the number of
-relations in the union can be omitted if it is 1:
-
-     # This is an iteration domain
-     DOMAIN
-     3 7 3 0 0 2                  # 3 rows, 7 cols: 3 output dims and 2 params
-     # e/i| i   j   k | M   N | 1
-        1  -1   0   0   1   0   0 #    -i + M >= 0
-        1   0  -1   0   0   1   0 #    -j + N >= 0
-        1   1   1  -1   0   0   0 # i + j - k >= 0
-
-As an example for unions, let us consider the following pseudo-code:
-
-     for (i = 1; i <= N; i++) {
-       if ((i >= M) || (i <= 2*M))
-         S1(i);
-     }
-
-The iteration domain of `S1' can be divided into two relations and
-written in the OpenScop file as follows:
-
-     # This is an iteration domain
-     DOMAIN
-     2 # Number of relations in the union
-     # Union part No.1
-     3 5 1 0 0 2          # 3 rows, 5 cols: 1 output dim and 2 params
-     # e/i| i | M   N | 1
-        1   1   0   0  -1 #  i >= 1
-        1  -1   0   1   0 #  i <= N
-        1   1  -1   0   0 #  i >= M
-     # Union part No.2
-     3 5 1 0 0 2          # 3 rows, 5 cols: 1 output dim and 2 params
-     # e/i| i | M   N | 1
-        1   1   0   0  -1 #  i >= 1
-        1  -1   0   1   0 #  i <= N
-        1  -1   2   0   0 #  i <= 2*M
-
-As an example for local dimensions (existentially quantified
-dimensions), let us consider the following pseudo-code:
-
-     for (i = 1; i <= N; i++) {
-       if ((i % 2) == 0)
-         S1(i);
-     }
-
-The iteration domain of `S1' is composed of all even integer values
-between 1 and N. The "divisible by two" constraint can be expressed as
-follows: there exists an integer `ld' such that `i = 2*ld'. We encode
-this thanks to a new local dimension:
-
-     # This is an iteration domain
-     DOMAIN
-     3 5 1 0 1 1          # 3 rows, 5 cols: 1 output dim, 1 local dim, 1 param
-     # e/i| i |ld | N | 1
-        0   1  -2   0   0 #  i = 2*ld
-        1   1   0   0   1 #  i >= 1
-        1  -1   0   1   0 #  i <= N

-3.2.1.2 Context Domain Relation
-...............................
-
-The context domain is a particular case of iteration domain (*note
-Iteration Domain Relation::) where there are only constraints about
-parameters (no loop iterators). Hence it is the same as an iteration
-domain, with the following conventions:
-   * the type is `CONTEXT',
-
-   * there is 0 input dimension,
-
-   * there is 0 output dimension.

-
-3.2.1.3 Scattering Relation
-...........................
-
-Scattering relation maps an iteration domain to a logical time and/or
-space (and/or) anything.  OpenScop scattering information is
-represented as relations (*note Relations::) with the following
-conventions:
-
-   * the type is `SCATTERING',
-
-   * output dimensions correspond to scattering dimensions,
-
-   * loop iterators correspond to input dimensions.
-
-   As an example of a scattering relation and assuming that `i', `j'
-and `k' are the loop iterators and `M' and `N' are the parameters, take
-for instance:
-     T_{S}(i,j,k) = (j+2,3*i+j,k+N+1).
-   We can represent it in the following way:
-
-     # A scattering relation
-     SCATTERING
-     # 3 rows, 10 columns: 3 scattering dimensions, 3 iterators, 2 parameters
-     3 10 3 3 0 2
-     # e/i|s1  s2  s3 | i   j   k | M   N | 1
-        0  -1   0   0   0   1   0   0   0   2 # s1 = j+2
-        0   0  -1   0   3   1   0   0   0   0 # s2 = 3*i+j
-        0   0   0  -1   0   0   1   0   1   1 # s3 = k+N+1

-
-3.2.1.4 Access Relation
-.......................
-
-Access relation maps an iteration domain to an array space.  Each array
-accessed in the SCoP has a unique identification number.  OpenScop
-relation information is represented as relations (*note Relations::)
-with the following conventions:
-
-   * the type is one of the following:
-        * `READ', for read accesses,
-
-        * `WRITE', for write accesses,
-
-        * `MAY_WRITE', for may write accesses,
-
-   * output dimensions correspond to the array identifier and
-     dimensions,
-
-   * the first output dimension corresponds to the array identifier,
-
-   * the (i+1)th output dimension corresponds to the ith array
-     dimension (i>1),
-
-   * loop iterators correspond to input dimensions.
-
-   As an example of a scattering relation and assuming that `i', `j'
-and `k' are the loop iterators and `M' and `N' are the parameters, let
-us consider the array access `A[2*i+j][j][i+N]' (the identifier of `A'
-is 42), and let us suppose this is a read access. Its representation
-would be the following:
-
-     # A read access relation
-     READ
-     # 4 rows, 11 columns: 4 array dimensions, 3 iterators, 2 parameters
-     4 11 4 3 0 2
-     # e/i|Arr [1] [2] [3]| i   j   k | M   N | 1
-        0  -1   0   0   0   0   0   0   0   0  42   # A
-        0   0  -1   0   0   2   1   0   0   0   0   #  [2*i+j]
-        0   0   0  -1   0   0   1   0   0   0   0   #         [j]
-        0   0   0   0  -1   1   0   0   0   1   0   #            [i+N]
-
-   To understand this representation, consider that OpenScop accesses
-are general memory accesses and not array accesses. The memory is seen
-as a big array `Mem' while usual array names correspond to the first
-dimension. Hence our example translates to `Mem[42][2*i+j][j][i+N]'.
-
-   Unions of access relations are allowed. In this case, each union
-part must refer at the same array identifier, and the number of
-dimensions must be consistent.

-3.2.2 Generics
---------------
-
-* Menu:
-
-* Strings Generic::
-* Body Generic::
-
-   _Generics_ represent any elaborated non-polyhedral information in the
-OpenScop format. They are used to represent the parameter information,
-the statement body information as well as the extensions. Each generic
-information is delimited using XML-like tags corresponding to its URI
-(Unique Resource Identifier), For instance, if the generic has the URI
-`foo', the begin tag is `<foo>' and the end tag is `</foo>').
-
-   Two generics, namely `strings' (*note Strings Generic::) and `body'
-(*note Body Generic::) are part of the OpenScop specification to
-provide the minimum, stricly necessary information to build a complete
-source-to-source polyhedral framework based on OpenScop.  However,
-generics can be basically _anything_ as long as they are properly
-delimited. OpenScop implementations will simply ignore non-supported
-generics and warn the user with the mention of the non-supported URIs.
-Support of new generics will be added throught the extension mechanism.

-
-3.2.2.1 Strings Generic
-.......................
-
-The purpose of the `strings' generic is to represent a list of textual
-strings on one line (which may be used, e.g., to represent the list of
-parameter names in the order used in the relation). Its URI is `strings'
-and its file format respects the following grammar:
-     Strings_generic     ::= "<strings>" Strings "</strings>"
-     Strings             ::= _String String_list  | (void)
-
-A possible example of textual `strings' is the following:

-
-3.2.2.2 Body Generic
-....................
-
-The purpose of the `body' generic is to represent the textual
-information about a statement. It contains the number of original
-iterators on the first line, the list of original iterators on the
-second line (the loop counters of the statement surrounding loops in
-the original program) and the original textual body expression on the
-third line.  Its URI is `body' and its file format respects the
-following grammar (the `String' rule is reused, *note Strings
-Generic::):
-     Body_generic        ::= "<body>" Body "</body>"
-     Body                ::= Nb_iterators Iterator_list Expression
-     Nb_iterators        ::= _Integer
-     Iterator_list       ::= Strings
-     Expression          ::= Strings
-
-A possible example of textual `body' is the following:

-     # Number of original iterators
-     2
-     # Original iterators
-     i j
-     # Original statement expression

-   The OpenScop specification offers a small set of C data structures
-devoted to represent a SCoP in memory in a convenient way. Using them
-in some tool or library may greatly facilitate its interaction with
-other tools or libraries which rely on this representation as well.
-Every field may not be useful for a given tool or library. A general
-rule for all the data structure is that a `NULL' pointer or a -1
-integer value means the information is not present. Contrary to
-engineering time, memory is cheap today, so it's much probably not a
-big deal that some fields are left empty. Every field may not be enough
-for a given tool or library. In this case it is much recommended to
-provide a new extension which may be reused by other users (*note
-Extensions::).
-
-   Each tool or library may have its own implementation of the OpenScop
-data structures. The type names should not be the same as those provided
-as an example here (they correspond to the OpenScop Library
-implementation).  The names of the fields, and their ordering, should
-however be the same. In this way, the interaction between tools and
-libraries should be as simple as a cast.
-
-   Before reading at the OpenScop data structures, it is much
-recommended to read at the OpenScop file format description, as it is
-quite close to this representation (*note OpenScop File Format
-Specification::).

-The `osl_statement_t' structure represents a node in a

-conventions (e.g. "S1" for the first statement in the list). The
-iteration domain and the scattering are represented using an
-`osl_relation_p' structure while the accesses are using a list of
-relations: one for each memory access in the statement.  The `body'
-field should provide information about the statement body (since it has
-a generic type, the specification is not strict about how it is used),
-e.g., using the `osl_body_t' data structure (*note osl_body_t::).  It

-`osl_scop_t' represents a node in a `NULL'-terminated list of scops. It
-stores the useful informations of a static control part of a program to
-process it within a polyhedral framework. To prepare OpenScop
-specification evolution, the `version' field tells the version of the
-data structure. It should be set to 1 for now (and hopefully a very,
-very, long time).  First, it contains the informations about the
-context. The target language in expressed in the `language' field. The
-constraints on the global parameters are detailed in the `context'
-field.  The `paremeters' field should provide information about the
-parameters (since it has a generic type, the specification is not strict
-about how it is used), e.g., using the `osl_strings_t' data structure
-(*note osl_strings_t::).  Finally, it contains the list of statements
-`statement', the list of registered interfaces for generic types
-`registry' and the list of extentions `extension'.  It is also possible
-to use the `usr' field, but it has to be totally managed by the user.
-
-   As an example, let us consider again the matrix multiply program
-(*note Preliminary Example::).  The next figure gives a possible
-representation in memory for this SCoP thanks to the OpenScop data
-structures (it has been actually printed by the `osl_scop_dump'
-function), note that symbols like parameters, original iterators and
-statement expression are represented with an `osl_strings_t' which does
-not belong to the specification but to the OpenScop Library

-3.4 Extensions
-==============
-
-The core part of the OpenScop representation embeds what is strictly
-necessary to build a complete source-to-source polyhedral framework.
-However it may not be enough. Hence, OpenScop offers a very flexible
-extension part. Actually, the only constraint to build an extension is
-to request the OpenScop maintainer for a unique extension name: its URI
-(ask the maintainer through the OpenScop mailing list
-<openscop-development@googlegroups.com>).
-
-   The policy to support extensions is the following and is pretty
-simple: an OpenScop implementation is not required to support any
-extension. If it is processing an OpenScop file or data structure which
-contains an extension which is not supported, it must (1) warn the user
-with the mention of the URI of the non-supported extension and (2)
-ignore this extension.
-
-   Extensions in an OpenScop file are provided after the core part,
-without any specific order. Each extension is delimited using XML-like
-tags corresponding to its URI (e.g., if the extension has the URI
-`foo', the begin tag is `<foo>' and the end tag is `</foo>').  There is
-no specification or preferred way to write the extension body.
-Extensions in an OpenScop data structure must be accessible through one
-pointer. This pointer will be stored in the `data' field of an
-`osl_generic_t' container (*note osl_generic_t::). There must be only
-one extension with the same URI in an OpenScop file or data structure.
-
-   Extension writers may write a short documentation about their
-extension to be added to this document. For consistency reason, this
-documentation should comply to the documentation of the `comment'
-option (*note Comment Extension::). To describe the file format, it is
-allowed to reuse the existing rules and terminals present in the
-OpenScop file format description without defining them (*note OpenScop
-File Format Specification::). By sending a documentation, you accept it
-to be added to this document. In particular, the sender fully accepts
-the license and copyright notice.

-3.4.1 Comment Extension
------------------------
-
-*Description*
-   * URI: `comment'.
-
-   * Author: Ce'dric Bastoul <cedric.bastoul@u-psud.fr>.
-
-   * Purpose: the `comment' extension stores a textual string.
-
-*File Format*
-
-The `comment' extension file format respects the following grammar:
-     Comment_generic     ::= "<comment>" Comment "</comment>"
-     Comment             ::= _Text
-
-An example of textual `comment' extension is the following:
-     <comment>
-     This is a comment string.
-     </comment>
-
-*Data Structure*
-
-The `comment' extension data structure is the following:
-     struct osl_comment {
-       char * comment;  /* Comment message as a 0-terminated string */
-     };
-     typedef struct osl_comment   osl_comment_t;
-     typedef struct osl_comment * osl_comment_p;

-3.4.2 Scatnames Extension
--------------------------
-
-*Description*
-   * URI: `scatnames'.
-
-   * Author: Ce'dric Bastoul <cedric.bastoul@u-psud.fr>.
-
-   * Purpose: the `scatnames' extension provides a list of textual
-     scattering dimension names.
-
-*File Format*
-
-The `scatnames' extension file format respects the following grammar.
-It reuses the `Strings' description (*note Strings Generic::):
-     Scatnames_generic   ::= "<scatnames>" Scatnames "</scatnames>"
-     Scatnames           ::= Strings
-
-The list of scattering dimension names is provided on one single line.
-The names are separated with spaces. A possible example of such an
-extension is the following:
-
-     <scatnames>
-     # List of scattering dimension names:
-     beta_0 i beta_1 j beta_2
-     </scatnames>
-
-*Data Structure*
-
-The `scatnames' extension data structure is the following:
-
-     struct osl_scatnames {
-       osl_strings_p names;  /* List of textual scattering dimension names. */
-     };
-     typedef struct osl_scatnames   osl_scatnames_t;
-     typedef struct osl_scatnames * osl_scatnames_p;
-
-The order of the scattering dimension names in the list corresponds to
-the order of the scattering dimensions.

-3.4.3 Arrays Extension
-----------------------
-
-*Description*
-   * URI: `arrays'.
-
-   * Author: Ce'dric Bastoul <cedric.bastoul@u-psud.fr>.
-
-   * Purpose: the `arrays' extension provides a set of textual array
-     names corresponding to the array identifiers used in the access
-     relations.
-
-*File Format*
-
-The `arrays' extension file format respects the following grammar:
-     Arrays_generic      ::= "<arrays>" Arrays "</arrays>"
-     Arrays              ::= Nb_items Item_list
-     Item_List           ::= Item Item_list | (void)
-     Item                ::= Identifier Name
-     Nb_items            ::= _Integer
-     Identifier          ::= _Integer
-     Name                ::= _String
-
-The number of array names is provided on the first line, then each
-following line contains a couple identifier-name.  For instance, the
-following example is a correct textual `arrays' extension. It
-corresponds to the array names of the preliminary example (*note
-Preliminary Example::):
-
-     <arrays>
-     # Number of array names:
-     3
-     1 C # Identifier 1 corresponds to array name "C"
-     3 B # Identifier 3 corresponds to array name "B"
-     2 A # Identifier 2 corresponds to array name "A"
-     </arrays>
-
-*Data Structure*
-
-The `arrays' extension data structure is the following:
-
-     struct osl_arrays {
-       int nb_names;      /* Number of names */
-       int  *  id;        /* Array of nb_names identifiers */
-       char ** names;     /* Array of nb_names names */
-     };
-     typedef struct osl_arrays   osl_arrays_t;
-     typedef struct osl_arrays * osl_arrays_p;
-
-Each name has a name string and an identifier: the ith name has name
-string `names[i]' and identifier `id[i]'.

-4 OpenScop Library
-******************
-
-The OpenScop Library, or OSL for short, is an example implementation of
-the OpenScop specification. Its API is not part of the OpenScop
-specification.  It offers basic functionalities to manipulate the
-OpenScop data structures (allocate, free, copy, dump, etc.) and file
-format (read, print, etc.).  The OpenScop Library is _not_ a polyhedral
-library. OpenScop is an exchange format, and the OpenScop Library
-reflects this.
-
-   It is a Free Software using the 3-clause BSD License.  Programmers
-should feel free to use it or copy/paste its code in any project, Open
-Source or not(1).

-4.1 Precision
-=============
-
-The OpenScop specification does not impose a specific type for the
-constraint matrix elements. For a maximum flexibility, the OpenScop
-Library offers an hybrid precision implementation. It supports 32 bits,
-64 bits and multiple precision (relying on GNU GMP) relations
-transparently. At relation allocation time, users have two ways to set
-the precision. The first way is to call an allocation function with a
-precision parameter. The second way is to rely on the environment
-variable `OSL_PRECISION'.  The accepted values for this variable are
-`32' for 32 bits precision, `64' for 64 bits precision and `0' for
-multiple precision. When this variable is set, its value becomes the
-default precision for relation elements.  For instance, to ensure the
-OpenScop Library will use 64 bits precision by default, the user may
-set:
-     export OSL_PRECISION=64
-   if his shell is, e.g., bash or
-     setenv OSL_PRECISION 64
-   if his shell is, e.g., tcsh. The user should ad this line to his
-.bashrc or .tcshrc (or whatever convenient file) to make this setting
-permanent.

-
-4.2 Base Functions
-==================
-
-The OpenScop Library provides, for each OpenScop data structure, a set
-of functions devoted to basic manipulation, conversion from file format
-to data structures and from data structures to file format. The naming
-convention is consistent for all data structures. Hence, the function
-prototypes differ only with the name of the data structure. In the
-following, we will use the generic term of _structure_ to refer at any
-OpenScop data structure. For instance the `osl_'_structure_`_malloc()'
-function is a generic name can be instantiated to
-`osl_relation_malloc()' or `osl_statement_malloc()' etc.
-
-   We present in this documentation only the main functions. Many other
-utility functions are provided to ease OpenScop format manipulation.
-The reader is invited to refer at the technical documentation to learn
-everything about the OpenScop Library.

-4.2.1 Dumping: osl__structure__dump and idump
----------------------------------------------
-
-     void osl__structure__dump(FILE * output, osl__structure__p s);
-     void osl__structure__idump(FILE * output, osl__structure__p s, int i);
-
-Each OpenScop data structure has a dumping functions as shown above.
-Dumping means writing down the content of the data structure pointed by
-`s' (and its fields recursively) in a textual form to the `output' file
-(the file, possibly `stdout', has to be open for writing). The textual
-form is not the OpenScop file format but another representation closer
-to the internal representation in memory and mainly intended for
-debugging purpose. The `idump' function has an additional integer
-parameter which corresponds to an indentation level.
-
-

-
-4.2.2 Printing: osl__structure__print
--------------------------------------
-
-     void osl__structure__print(FILE * output, osl__structure__p s);
-
-Each OpenScop data structure has a pretty printing function as shown
-above. It prints the content of the data structure pointed by `s' (and
-its fields recursively) according to the OpenScop file format (*note
-OpenScop File Format Specification::) to the `output' file (the file,
-possibly `stdout', has to be open for writing).
-
-
-File: openscop.info,  Node: Reading,  Next: Allocating,  Prev: Printing,  Up: Base Functions
-
-4.2.3 Reading: osl__structure__read
------------------------------------
-
-     osl__structure__p osl__structure__read(FILE * input);
-
-Each OpenScop data structure has a reading function as shown above. It
-reads the content of an OpenScop data structure written according to
-the OpenScop file format (*note OpenScop File Format Specification::)
-from the `input' file (the file, possibly `stdin', has to be open for
-reading). It returns a pointer to a freshly allocated
-`osl__structure__t' structure containing the information.
-
-
-File: openscop.info,  Node: Allocating,  Next: Deallocating,  Prev: Reading,  Up: Base Functions
-
-4.2.4 Allocating: osl__structure__malloc
-----------------------------------------
-
-     osl__structure__p osl__structure__malloc();
-
-Each OpenScop data structure has a memory allocation function as shown
-above (except one see below). It allocates the memory to store the
-corresponding data structure, it initializes the pointer fields to
-`NULL' and the integer fields to `OSL_UNDEFINED' (`-1') and it returns
-a pointer to the allocated space.
-
-   An exception to this base description is the `osl_relation_malloc()'
-function which requires two parameters: the number of rows and columns
-of the constraint matrix (*note Relations::):
-
-     osl_relation_p osl_relation_malloc(int nb_rows, int nb_columns);
-
-The precision of the relation elements will depend on the
-`OSL_PRECISION' environment variable (*note Precision::) if it is set,
-or the maximum available precision if it is not set. Another allocation
-function is provided to explicitly set a given precision:
-
-     osl_relation_p osl_relation_pmalloc(int precision,
-                                         int nb_rows, int nb_columns);
-
-The `precision' field may take the following values:
-   * `OSL_PRECISION_SP' for 32 bits precision,
-
-   * `OSL_PRECISION_DP' for 64 bits precision,
-
-   * `OSL_PRECISION_MP' for multiple precision,
-

-
-4.2.5 Deallocating: osl__structure__free
-----------------------------------------
-
-     void osl__structure__free(osl__structure__p s);
-
-Each OpenScop data structure has a memory deallocation function as
-shown above. It recursively frees the memory allocated for the
-structure pointed by `s', i.e., internal structures are also freed.
-
-
-File: openscop.info,  Node: Cloning,  Next: Testing,  Prev: Deallocating,  Up: Base Functions
-
-4.2.6 Cloning: osl__structure__clone
-------------------------------------
-
-     osl__structure__p osl__structure__clone(osl__structure__p s);
-
-Each OpenScop data structure has a clone function as shown above. It
-recursively copies the content of the structure pointed by `s', i.e.,
-internal structures are also copied.  It returns a pointer to the clone
-of the structure pointed by `s'.
-
-
-File: openscop.info,  Node: Testing,  Prev: Cloning,  Up: Base Functions
-
-4.2.7 Testing: osl__structure__equal
-------------------------------------
-
-     int osl__structure__equal(osl__structure__p s1, osl__structure__p s2);
-
-Each OpenScop data structure has a testing function as shown above. It
-checks whether two pointers are referring to equivalent structures
-(either by pointing to the same structure or to different structures
-which contain the same information). It returns 1 if the pointed
-structures are equivalent, 0 otherwise. This test is _content-based_
-and is intended for debugging purpose. It is not (and will never be)
-able to state, e.g., that two relations with different constraint
-matrices are actually representing the same relation.

-4.3 Example of OpenScop Library Utilization
-===========================================
-
-Here is a basic example showing how it is possible to use the OpenScop
-Library, assuming that a standard installation has been done.  The
-following C program reads an OpenScop file from the standard input and
-dumps the content of the data structures to the standard output.
-
-     /* example.c */
-     # include <stdio.h>
-     # include <osl/osl.h>
-
-     int main() {
-       osl_scop_p scop;
-
-       // Read the OpenScop file.
-       scop = osl_scop_read(stdin);
-
-       // Dump the content of the scop data structure.
-       osl_scop_dump(stdout, scop);
-
-       // Save the planet.
-       osl_scop_free(scop);
-
-       return 0;
-     }
-
-The compilation command could be:
-     gcc example.c -losl -o example
-   A calling command with the input file test.scop could be:
-     more test.scop | ./example

-4.4.2 Requirements
-------------------
-
-The OpenScop Library is a stand-alone library. For a basic use, it does
-not need any additional tool or library. Anyway, to be able to work in
-conjunction with other tools that manipulate multiple precision
-numbers, the GNU GMP library can be used as an option.
-
-* Menu:
-
-* GMP Library::
-
-
-File: openscop.info,  Node: GMP Library,  Up: Requirements
-
-4.4.2.1 GMP Library (optional)
-..............................
-
-To be able to deal with insanely large coefficient, the user will need
-to install the GNU Multiple Precision Library (GMP for short) version
-4.2.2 or above(1).  The user can compile it by typing the following
-commands on the GMP root directory:
-
-   * `./configure'
-
-   * `make'
-
-   * And as root: `make install'
-
-   The GMP default installation is `/usr/local'. This directory may not
-be inside the user's library path. To fix the problem, the user should
-set
-     export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
-   if your shell is, e.g., bash or
-     setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/usr/local/lib
-   if your shell is, e.g., tcsh. Add the line to your .bashrc or
-.tcshrc (or whatever convenient file) to make this change permanent.
-Another solution is to ask GMP to install in the standard path by using
-the prefix option of the configure script: `./configure --prefix=/usr'.
-
-   The OpenScop Library has to be built using the GMP library by
-specifying the convenient configure script options to buid the GMP
-version (*note Optional Features::).

-
-4.4.3 Installation Instructions
--------------------------------
-
-Once downloaded and unpacked (e.g. using the `tar -zxvf
-openscop-0.8.1.tar.gz' command), you can compile the OpenScop Library
-by typing the following commands on the OpenScop Library's root
-directory:
-
-   * `./autogen.sh'
-
-   * `./configure'
-
-   * `make'
-
-   * And as root: `make install'
-
-   The program binaries and object files can be removed from the source
-code directory by typing `make clean'. To also remove the files that
-the `configure' script created (so you can compile the package for a
-different kind of computer) type `make distclean'.
-
-
-File: openscop.info,  Node: Optional Features,  Next: Uninstallation,  Prev: Installation Instructions,  Up: Installation
-
-4.4.4 Optional Features
------------------------
-
-The `configure' shell script attempts to guess correct values for
-various system-dependent variables and user options used during
-compilation.  It uses those values to create the `Makefile'. Various
-user options are provided by the OpenScop Library's configure script.
-They are summarized in the following list and may be printed by typing
-`./configure --help' in the OpenScop Library top-level directory.
-
-   * By default, the installation directory is `/usr/local': `make
-     install' will install the package's files in `/usr/local/bin',
-     `/usr/local/lib' and `/usr/local/include'.  The user can specify
-     an installation prefix other than `/usr/local' by giving
-     `configure' the option `--prefix=PATH'.
-
-   * By default, The OpenScop Library is built in 64bits version.  If
-     the user gives to `configure' the option `--enable-int-version',
-     the 32bits version of the OpenScop Library will be compiled. In
-     the same way, the option `--enable-mp-version' has to be used to
-     build the multiple precision version.
-
-   * By default, `configure' will look for the GMP library (necessary
-     to build the multiple precision version) in standard locations. If
-     necessary, the user can specify the GMP path by giving `configure'
-     the option `--with-gmp=PATH'.

-
-4.5 Documentation
-=================
-
-The OpenScop Library distribution provides several sources of
-documentation.  First, the source code itself is as documented as much
-as possible.  The code comments use the Doxygen technical documentation
-system.  The user may install Doxygen(1) to automatically generate a
-technical documentation by typing `make doc' or `doxygen
-./autoconf/Doxyfile' at the OpenScop Library top-level directory after
-running the configure script (*note Installation Instructions::).
-Doxygen will generate documentation sources (in HTML, LaTeX and man) in
-the `doc/source' directory of the OpenScop Library distribution.
-
-   The Texinfo source of the present document is also provided in the
-`doc' directory. The user can build it in either PDF format (by typing
-`texi2pdf openscop.texi') or HTML format (by typing `makeinfo --html
-openscop.texi', using `--no-split' option to generate a single HTML
-file) or info format (by typing `makeinfo openscop.texi').

-4.6.1 Copyright Issue
----------------------
-
-The OpenScop Library is an Open Source project and you should feel free
-to contribute by adding functionalities (in particular extensions),
-correcting bugs or improving documentation. However, for painful
-administrative reasons, the copyright of the core part (everything
-except extensions) should not be impacted by your work. Hence, if you
-are doing a significant contribution to the main part, the OpenScop
-Library maintainer may ask you for an agreement about this copyright.
-If you plan to do such a significant contribution, it may be wise to
-discuss this issue with the maintainer first. Extensions may include
-developer's own copyright.
-
-
-File: openscop.info,  Node: Repository,  Next: Coding Style,  Prev: Copyright Issue,  Up: Development
-
-4.6.2 Repository
-----------------
-
-The main repository of the OpenScop Library is
-`http://repo.or.cz/w/openscop.git'. Developers may ask the OpenScop
-Library maintainer to open them a write access to this repository. Only
-the maintainer should ever change the `master' branch. Developers
-should work on their own branches. To avoid any problem developers
-should use the _fork_ functionality of the repository.
-
-
-File: openscop.info,  Node: Coding Style,  Next: Extension Development,  Prev: Repository,  Up: Development
-
-4.6.3 Coding Style
-------------------
-
-The OpenScop Library is written in C using an object oriented style.
-Each important data structure (e.g., `struct foo') has its own header
-file (`include/osl/foo.h') where lies the definition of the data
-structure, the two typedefs for the data structure (one for the
-structure, `osl_foo_t', and one for a pointer to the structure,
-`osl_foo_p'), the prototypes of the various functions related to this
-data structure, all named using the prefix "`osl_foo_'". The source
-code of the functions is provided in a separated C file
-(`source/foo.c').
-
-   Utility functions independent from the main data structures may be
-placed in separate source files (e.g., definition in
-`include/osl/util.h' and code in `source/util.c'). Tool-wide
-preprocessor directives are placed in `include/osl/macros.h', macros
-are prefixed with "`OSL_'".
-
-   The core code itself has to be written according to the Google C++
-Coding Style:
-`http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml' (for
-what can apply to C), plus the naming conventions discussed above with
-highest priority. The extension parts must only respect the naming
-convention, but a consistent coding style is much appreciated.
-
-
-File: openscop.info,  Node: Extension Development,  Prev: Coding Style,  Up: Development
-
-4.6.4 Extension Development
----------------------------
-
-It's fairly easy to integrate a new extension to OpenScop and the
-OpenScop Library. Developing a new extension is very much like adding a
-new "object": it requires writing a data structure for the extension
-data and the 7 base functions to manage this extension. Here is how
-developers should proceed to add an extension called `foo' (beware that
-the naming convention is strict):
-
-  1. Send the name `foo' to the maintainer to ensure it is unique and
-        hence can be used as an URI. The name (one single       word,
-     or words separated with underscores "_") should be       suggested
-     by the extension developers to the OpenScop development
-     mailing list <openscop-development@googlegroups.com>). It
-     should not correspond to an existing structure name       (see
-     `include/osl/osl.h' for the list). The       maintainer will
-     update `include/osl/osl.h' in the development       version
-     accordingly.
-
-  2. Look at the `comment' extension. The `comment' extension
-     (*note Comment Extension::) has been written to be used as a basic
-          example for extension developers. Having a look at
-     `include/osl/extensions/comment.h' and
-     `source/extensions/comment.c' will be a great help to do it right.
-
-  3. Create the extension data structure: it is necessary that the
-     extension data can be accessible through only one pointer.
-
-  4. Code the 7 base functions for the extension. Any extension must
-     provide       this set of functions (naming convention apply only
-     if the       extension is planed to be integrated to the OpenScop
-     Library       default extensions):
-        * `osl_foo_idump' (*note Dumping::)
-
-        * `osl_foo_sprint' has the following prototype:
-               char * osl__structure__sprint(osl__structure__p s);
-                     It corresponds to the pretty printing functions of
-          the core            data structures (*note Printing::) with
-          the            difference that the OpenScop textual
-          representation is written            to a string (returned by
-          the function) instead of a file.
-
-        * `osl_foo_sread' has the following prototype:
-               osl__structure__p osl__structure__sread(char ** string);
-                     It corresponds to the reading functions of the core
-                    data structures (*note Reading::) with the
-           difference that the OpenScop textual representation is read
-                   from a string (provided as a parameter) instead of a
-          file.             The address of the string to read is passed
-          as a parameter and            is updated to point immediately
-          after what has been actually read.
-
-        * `osl_foo_malloc' (*note Allocating::)
-
-        * `osl_foo_free' (*note Deallocating::)
-
-        * `osl_foo_clone' (*note Cloning::)
-
-        * `osl_foo_equal' (*note Testing::)
-
-  5. Code the other functions you need!
-
-   Now let us consider two scenarios.
-
-   First scenario, the extension is external and is not planned to be
-integrated to the OpenScop Library. In this case you are all set.
-Simply generate an `osl_interface_t' for your extension and have a look
-at the function `osl_scop_register_extension()' which is devoted to
-register a new extension interface to an existing `osl_scop_t'.
-
-   Second scenario, the extension will integrate the set of default
-OpenScop Library extensions (the best solution to share it to other
-potential users). In this case, a few additional things have to be done:
-  1. Create the extension header       `include/osl/extensions/foo.h'
-     to store the extension       structure and function prototypes and
-     the       extension source file `source/extensions/foo.c' for the
-     code       of the functions.
-
-  2. Add the documentation for the extension to the texinfo source of
-        this document (in `doc/openscop.texi'), following the example
-        of the `comment' documentation (*note Comment Extension::).
-
-  3. Integrate the extension by adding the `extensions/foo.c' entry
-      to the `libosl_la_SOURCES' in the `source/Makefile.am'
-     file, the `osl/foo.h' entry to the
-     `nobase_pkginclude_HEADERS' and add the corresponding
-     `#include <osl/extensions/foo.h>' in the       `include/scop.h.in'
-     file.
-
-  4. Add the new extension in the
-     `osl_interface_get_default_registry()' function.
-
-  5. You are done! Prepare a single commit or patch corresponding to the
-          integration of the new extension and ask the maintainer to
-     merge it       to the master branch.

-@node Introduction
-@chapter Introduction
-OpenScop is an open specification that defines a file format and a set of
-data structures to represent a @emph{static control part} (SCoP for short),
-i.e., a program part that can be represented in the @emph{polyhedral model}.
-The goal of OpenScop is to provide a common interface to various
-polyhedral compilation tools in order to simplify their interaction. 
-
-Designing a single format for tools that have different purposes
-(e.g., as different as code generation and data dependence analysis) may
-sound strange at first. However we could observe that most available
-polyhedral compilation tools during the last decade were manipulating
-more or less the same kind of data (polyhedra, affine functions...) and
-were actually sharing a part of their input (e.g., iteration domains and
-context concepts are nearly everywhere). We could also observe that
-those tools may rely on different internal representations, mostly based on
-one of the major polyhedral libraries (e.g., Polylib, PPL or isl), and
-this representation may change over time (e.g., when switching to a
-more convenient polyhedral library).
-The OpenScop aim is to provide a stable, unified format that offers a
-durable guarantee that a tool can use an output or provide an input to
-another tool without breaking a tool chain because of some internal
-changes in one element of the chain. The other promise of OpenScop is
-the ability to assemble or replace the basic blocks of a polyhedral
-compilation framework at no, or at least low engineering cost.
-
-The policy that drives OpenScop can be summarized by these three rules:
-@itemize @bullet
-@item  Embed the @emph{minimum} information to build a complete polyhedral
-       compilation framework in the so-called @emph{core part}
-       (to avoid as much as possible empty or useless information
-       for each tool).
-@item  Provide a @emph{very stable} core part (so users have some
-       guarantee that they will not need to update their tool
-       because of frequent specification evolution),
-@item  Provide a @emph{very flexible} extension part (so it can also
-       be used to test wild new ideas).
-@end itemize
-
-@noindent Another, more technical, rule may be added:
-@itemize @bullet
-@item  Avoid any need for external library or tool to support it
-       (i.e., it's not XML or YAML or anything like that).
-@end itemize
-
-The success of OpenScop in meeting its goals totally depends on its
-acceptance by the tool developers (that have to support it in their tools).
-To help them, we provide an example implementation: the OpenScop Library.
-This library (and in particular its API) is not part of the OpenScop
-specification (which includes only the file format and the set of data
-structures). It is licensed under the 3-clause BSD license so developers may
-feel free to use it in their code (either by linking it or copy-pasting its
-code). This document also describes this library briefly (readers are
-invited to read at its technical documentation).
-The current version of the OpenScop Library is still under evaluation,
-and there is no guarantee that the upward compatibility will be respected,
-even if we do think so. A lot of reports are
-necessary to freeze the library API. Thus you are very welcome and
-encouraged to send reports on bugs, wishes, critics, comments, suggestions
-or (please!) successful experiences to the OpenScop mailing list
-@email{openscop-development@@googlegroups.com}.
-
-This document is organized as follows. First, we provide some
-background on the polyhedral model and how it is used to represent and to
-manipulate programs (@pxref{Polyhedral Representation}). Next,
-we describe the OpenScop specification, from the file format
-(@pxref{OpenScop File Format Specification}) to the data structures
-and the OpenScop Library API
-(@pxref{OpenScop Data Structure Specification}).
-Finally we will detail how to install the OpenScop Library
-(@pxref{Installation}).

-@node Polyhedral Representation
-@chapter Polyhedral Representation of Programs
-If you are reading at the OpenScop documentation, you probably don't need any
-explanation about the polyhedral model. It is unlikely that someone will read
-this paper by mistake. However some vicious advisor may ask their poor
-engineers/interns/students
-to work for the very first time on this exciting topic. Most papers on
-polyhedral compilation are hard to read. Despite my efforts,
-mine are no exception according to some reviewers. Hence I give there a new
-try to provide a comprehensive explanation of the polyhedral model without the
-size and style limits of a classical research paper.
-
-Be aware that to be able to understand the polyhedral model, there are a few
-prerequisites. You should not read the following while you still ignore
-what is:
-@itemize @bullet
-@item  a @code{for} loop construction in C programs (@code{do} loops in FORTRAN are OK too!),
-@item  an @emph{affine expression},
-@item  a @emph{vector},
-@item  a @emph{matrix},
-@item  a @emph{matrix-vector multiply}.
-@end itemize
-If you do not know those concepts, please do some search and come back
-afterwards. And if you are courageous enough, send me a few lines that
-describe them so I can insert them here!

-@node Motivation
-@section Motivation: Program Transformations
-
-A direct translation of high level programs written, e.g., in C, to assembly
-then to object code is likely to produce (very) inefficient applications.
-Architectures are
-quite complex, including several levels of cache memory, many cores, deep
-pipelines, various number of functional units, of registers etc.
-The list of such
-"architectural features" is growing with each new generation of processors.
-To achieve the best performance, the object program must use
-these features in a smart way.
-Programmers use high level languages for productivity and portability:
-typically they do not have to take care of the target architecture but
-to ensure they write programs which produce the right output. Hence,
-the problem of mapping the program to the target architecture in the most
-efficient way is left to the compiler.
-
-The compiler may see a high level program as a specification
-@emph{of an output}. The program is a list of instructions to be executed to
-produce the output. As long as the output is guaranteed to be as the
-programmer specified in his code, the compiler is free to modify
-the program.
-For instance, let us imagine we are working on an architecture with only
-three registers and we consider the following statements written by
-a programmer:
-
-@example
-@group
-x = a + b;
-y = c + d;
-z = a * b;
-@end group
-@end example
-
-It is easy to see that we can reorder the three statements in any way without
-modifying the semantics (no statement reads or writes a variable that another
-statement writes). Because of the lack of registers, the solutions such that
-the first and the third statements are one after the other are better
-because @code{a} and @code{b} will be put in the processor registers by
-one statement and can be reused directly by the other one
-without reading from memory (this is called a @emph{data locality
-improving} transformation). Hence a better statement order is, e.g.:
-
-@example
-@group
-x = a + b;
-z = a * b; // a and b are still in processor registers
-y = c + d;
-@end group
-@end example
-
-We can also notice that it is possible to run the three statements in
-parallel (possibly on different processors). The programmer may
-explicit this in a way the compiler
-and/or the architecture is able to understand. For instance,
-we can use OpenMP to describe parallelism
-(this is called a @emph{parallelizing} transformation):
-
-@example
-@group
-#pragma omp parallel sections
-@{
-   #pragma omp section
-   @{
-     x = a + b;
-   @}
-   #pragma omp section
-   @{
-     y = c + d;
-   @}
-   #pragma omp section
-   @{
-     z = a * b;
-   @}
-@}
-@end group
-@end example
-
-However, the right way to optimize this program is probably a tradeoff
-between these two techniques. This is true if, e.g., the target
-architecture has some limitations to run too many operations in parallel,
-or, like in our case, when some data may be reused by some processors.
-Hence, the best optimization for our small example is probably the
-following:
-
-@example
-@group
-#pragma omp parallel sections
-@{
-   #pragma omp section
-   @{
-     x = a + b;
-     z = a * b;
-   @}
-   #pragma omp section
-   @{
-     y = c + d;
-   @}
-@}
-@end group
-@end example
-
-This example is quite trivial because the statements are
-executed only once. The real sport begins when we have to deal with loops,
-as we will see momentarily. However, polyhedral compilation framework users
-have to be conscious that we @emph{need} to transform programs to achieve
-the best performance and that the best transformation  that has to be
-discovered (at the price of many, many efforts) and performed may be
-quite complex. Hence the need of powerful model and tools.
-
-
-@node Thinking in Polyhedra
-@section Thinking in Polyhedra
-
-
-Since the very first compilers, the internal representation of programs
-is the @emph{Abstract Syntax Tree}, or AST. In such representation,
-each statement appears only once even if it is executed many times (e.g.,
-when it is enclosed inside a loop). This is a limitation
-for finding and applying complex transformations:
-@itemize @bullet
-@item It limits program analysis power. For instance if a statement
-      @emph{depends} on another statement (i.e., they access the same
-      memory location and at least one of these accesses is a write),
-      we will consider both statements as unique entities while the
-      dependence relation may involve only few statement executions.
-@item It limits program transformation power. Loop transformations
-      operate on statement executions. For instance, because they
-      consider all statement executions at the same time, present day
-      production compilers are not able to achieve loop fusion
-      (that tries to merge the loop bodies of two loops) if the loop bounds
-      of the two loops do not match (yes, that's ridiculous).
-@item It limits program manipulation flexibility.
-      Trees are very rigid data structures that are not easy to manipulate.
-      Program transformation may require very complex transformations that will
-      imply deep modifications of the control flow.
-@end itemize
-
-The Polyhedral Model is a convenient alternative representation which
-combines analysis power, expressiveness and high flexibility. The drawback
-is it breaks the classical structure of programs that every programmer
-is familiar with. It requires some (real) efforts
-to be smoothly manipulated, but it definitely worth it. It is based on three
-main concepts, @emph{iteration domain},  @emph{scattering function} and
-@emph{access function} that are described in depth in the
-following sections.
-
-A program part that can be represented using the Polyhedral Model is called
-a @strong{Static Control Part} or @strong{SCoP} for short.
-
-@menu
-* Iteration Domain::
-* Scattering Function::
-* Access Function::
-@end menu
-
-@node Iteration Domain
-@subsection Iteration Domain
-
-The key aspect of the polyhedral model is to consider @emph{statement
-instances}. A statement instance is @emph{one} execution of a statement.
-A statement
-outside a loop has only one instance while those inside loops may have many.
-Let us consider the following code with two statements @code{S1}
-and @code{S2}:
-
-@example
-@group
-pi = 3.14;               // S1
-for (i = 0; i < 5; i++)
-  A[i] = pi;             // S2
-@end group
-@end example
-
-The list of statement instances is the following (we just have to fully
-unroll the loop):
-
-@example
-@group
-pi = 3.14;
-A[0] = pi;
-A[1] = pi;
-A[2] = pi;
-A[3] = pi;
-A[4] = pi;
-@end group
-@end example
-
-Each instance of a statement which is enclosed inside a loop may be referred
-thanks to its outer loop counters (or @emph{iterators}). In the polyhedral
-model we consider statements as functions of the outer loop counters that may
-produce statement instances:
-instead of simply "@code{S2}", we use preferably the notation @code{S2(i)}.
-For instance we  denote the statement instance @code{A[3] = pi;} of the
-previous example as @code{S2(3)}. This means @emph{instance of
-statement @code{S2} for} @code{i = 3}.
-If a statement @code{S3} is enclosed inside two loops of iterators @code{i}
-(outermost loop) and @code{j} (innermost loop), we would denote it
-@code{S3(i,j)}, and so on with more enclosing loops.
-
-The ordered list
-of iterators (ordered from the outermost iterator to the innermost iterator)
-is called the @strong{iteration vector}. For instance the iteration vector for
-@code{S3} is @code{(i,j)}, for @code{S2} it is @code{(i)}, and for @code{S1}
-it is empty since it has no enclosing loop: @code{()}. A more precise reading
-at the notation @code{S2(3)} would show that it denotes the instance of
-statement @code{S2} for the iteration vector @code{(2)}.
-
-Obviously, dealing with statement instances does not mean we have to unroll all
-loops. First because there would be probably too many instances to deal with,
-and second because we probably just do not know how many instances there are.
-For instance in the following loop it is impossible to know (at compile time)
-how many times the statement @code{S3} will be executed:
-
-@example
-@group
-for (i = 2; i <= N; i++)
-  for (j = 2; j <= N; j++)
-    A[i] = pi;             // S3
-@end group
-@end example
-
-@noindent Such a loop is said to be @emph{parametric}: it depends on
-(at least) a value called a @emph{parameter} which is not modified
-during the execution of the whole loop, but is unknown at compile time.
-Here, the only parameter is @code{N}.
-
-A compact way to represent all the instances of a given statement
-is to consider the set of all possible values of its iteration vector.
-This set is called the @strong{iteration domain}. It can be conveniently
-described thanks to all the constraints on the various iterators the statement
-depends on. For instance, let us consider
-the statement @code{S3} of the previous program. The iteration domain is the set
-of iteration vectors @code{(i,j)}. Because of the parameter, we are not able to
-achieve a precise list of all possible values. It would look like this:
-
-@example
-@group
-(2,2)  (2,3)  (2,4)  ...  (2,N)
-(3,2)  (3,3)  (3,4)  ...  (3,N)
-...    ...    ...    ...  ...

-We often use in our research papers a graphical representation that gives a
-better view of this subspace:
-
-@image{images/basic1,4cm}
-
-@noindent Here, the iteration domain is specified thanks to a set of
-constraints. When those constraints are affine and
-depend only on the outer loop counters and some parameters, the set of
-constraints defines a @emph{polyhedron} (more precisely this is a
-@emph{Z-polyhedron}, but we use @emph{polyhedron} for short).
-Hence the @emph{polyhedral model}!
-
-To manipulate a set of affine constraints easily, we rely on a matrix
-representation. To write it, we use the @emph{homogeneous} iteration vector:
-it is simply the iteration vector with some additional dimensions to
-represent the parameters and the constant.
-For instance for the statement @code{S3}, the
-iteration vector in homogeneous coordinates is @code{(i, j, N, 1)}
-(we will now call it @emph{iteration vector} directly for short).
-Then we write all the constraints as affine inequalities of the form
-@emph{affine constraint}
-@tex
-$\geq 0$.
-@end tex
-@ifnottex
-@code{ >= 0}.
-@end ifnottex
-For instance for the statement @code{S3} the set of constraints is:
-

-                -i     + N      &$\geq 0$\cr

-@node Scattering Function
-@subsection Scattering Function
-
-There is no ordering information inside the iteration domain: it only describes
-the set of statement instances but @strong{not} the order in which they have
-to be executed relatively to each other. In the past the lexicographic order
-of the iteration domain was considered, this is no more true
-(especially when using CLooG). If we do not provide any ordering information, this
-means that the statement instances may be executed in any order
-(this is useful, e.g., to specify parallelism). However, some statement instances
-may depend on some others and it may be critical to enforce a given order (or
-non-order). Hence we need another information.
-
-We call @emph{scattering} any kind of ordering information in the polyhedral
-model. There exists many kind of ordering, such as @emph{allocation},
-@emph{scheduling}, @emph{chunking} etc. They are all expressed
-in the same way, i.e., using @emph{logical stamps}, but they may have
-different semantics.
-
-In the case of @strong{scheduling}, the logical stamps are logical dates that
-express at which date a statement instance has to be executed. For instance,
-let us consider the following three statements:
-
-@example
-@group
-x = a + b;   // S1
-y = c + d;   // S2
-z = a * b;   // S3
-@end group
-@end example
-
-@noindent The scheduling of a statement @code{S} is typically
-denoted by
-@tex
-$\theta_{S}$.
-@end tex
-@ifnottex
-T_S.
-@end ifnottex
-Let us consider the following logical dates for each statement:
-
-@tex
-@example
-@group
-$\theta_{S1} = 2$
-$\theta_{S2} = 3$
-$\theta_{S3} = 1$
-@end group
-@end example
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1 = 1
-T_S2 = 2
-T_S3 = 3
-@end group
-@end example
-@end ifnottex
-
-@noindent It means that statement @code{S3} has to be executed at logical date
-@code{1}, statement @code{S1} has to be executed at logical date
-@code{2} and statement @code{S2} has to be executed at logical date
-@code{3}. The target code has to respect this scheduling (the order of
-the logical dates), hence it would look like the following where the
-variable @code{t} denotes the time:
-
-@example
-@group
-t = 1;
-z = a * b;   // S3
-t = 2;
-x = a + b;   // S1
-t = 3;
-y = c + d;   // S2
-@end group
-@end example
-
-@noindent When some statements share the same logical date, this means that,
-once the program reaches this logical date, the two statements can be executed
-in any order, or better, in parallel. For instance let us consider the
-following scheduling:
-
-@tex
-@example
-@group
-$\theta_{S1} = 1$
-$\theta_{S2} = 2$
-$\theta_{S3} = 1$
-@end group
-@end example
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1 = 1
-T_S2 = 2
-T_S3 = 1
-@end group
-@end example
-@end ifnottex
-
-@noindent Statements @code{S1} and @code{S3} have the same logical date,
-moreover, @code{S2} has a greater logical date than @code{S1} and @code{S3}.
-Hence the target code would be:
-
-@example
-@group
-t = 1;
-#pragma omp parallel sections
-@{
-   #pragma omp section
-   @{
-     x = a + b;   // S1
-   @}
-   #pragma omp section
-   @{
-     z = a * b;   // S3
-   @}
-@}
-t = 2;
-y = c + d;        // S2
-@end group
-@end example
-
-Logical dates may be multidimensional, as clocks: the first dimension
-may correspond to days (most significant), the next one to hours (less
-significant), the third to minutes and so on. For instance we can consider
-the following multidimensional schedules for our example:
-
-@tex
-@example
-@group
-$\theta_{S1} = (1,1)$
-$\theta_{S2} = (2,1)$
-$\theta_{S3} = (1,2)$
-@end group
-@end example
-@end tex
-
-@ifnottex
-@example
-@group
-T_S1 = (1,1)
-T_S2 = (2,1)
-T_S3 = (1,2)
-@end group
-@end example
-@end ifnottex
-
-@noindent It is not very hard to decypher the meaning of such scheduling.
-Because of the first dimension, statements @code{S1} and @code{S3} will be
-executed before statement @code{S2} (@code{S1} and @code{S3} are executed at
-day 1, while @code{S2} is executed at day 2). The second dimension is not
-really useful there for @code{S2} because it is the only statement executed
-at day 2. Nevertheless it allows to order @code{S1} and
-@code{S3} relatively to each other since @code{S1} is executed at hour 1 of day
-1 while @code{S3} is executed at hour 2 of day 1.
-The corresponding target code is the following, with some
-additional time variables for a better view of the ordering (@code{t1}
-corresponds to the first time dimension, @code{t2} to the second one):
-
-@example
-@group
-t1 = 1;
-t2 = 1;
-x = a + b;   // S1
-t2 = 2;
-z = a * b;   // S3
-t1 = 2;
-t2 = 1;
-y = c + d;   // S2
-@end group
-@end example
-
-In the case of @strong{allocation} (in the literature we can find some
-papers calling it @emph{placement}), the logical stamp is a processor
-number expressing on which processor a statement instance has to be
-executed. Typically, allocations are written in the same way as scheduling.
-Here, we denote it @math{P_S} for a statement @code{S}.
-For instance, let us consider the following allocation:
-
-@tex
-@example
-@group
-$P_{S1} = 1$
-$P_{S2} = 2$
-$P_{S3} = 1$
-@end group
-@end example
-@end tex
-
-@ifnottex
-@example
-@group
-P_S1 = 1
-P_S2 = 2
-P_S3 = 1
-@end group
-@end example
-@end ifnottex
-
-@noindent The corresponding target code has to take into account that both
-statements @code{S1} and @code{S3} have to be executed on the same processor
-(they have the same logical number 1) and that statement @code{S2} has
-to be executed on another processor (logical number 2). A possible target code
-is the following:
-
-@example
-@group
-#pragma omp parallel sections
-@{
-   #pragma omp section
-   @{
-     // Logical processor 1
-     x = a + b;   // S1
-     z = a * b;   // S3
-   @}
-   #pragma omp section
-   @{
-     // Logical processor 2
-     y = c + d;   // S2
-   @}
-@}
-@end group
-@end example
-
-@noindent We can note that no order has been specified for the
-statements @code{S1} and @code{S3} that are executed on the same processor.
-Hence any order is satisfying. For sake of flexibility, it is usual to build
-a scattering whose various dimensions do not have the same semantics. A
-typical construction is @emph{space/time mapping} where the first @code{n}
-dimensions are devoted to allocation, then the last @code{m}
-dimensions are devoted to scheduling. Typically, space/time mapping is
-written in the same way as scheduling.
-Here we denote it @math{M_S} for a statement @code{S}.
-For instance, let us consider the following space/time mapping for our
-example where one dimension is devoted to mapping and one dimension is
-devoted to scheduling:
-
-@tex
-@example
-@group
-$M_{S1} = (1,2)$
-$M_{S2} = (2,1)$
-$M_{S3} = (1,1)$
-@end group
-@end example
-@end tex
-
-@ifnottex
-@example
-@group
-M_S1 = (1,2)
-M_S2 = (2,1)
-M_S3 = (1,1)
-@end group
-@end example
-@end ifnottex
-
-@noindent Here we have the same first dimension as the previous example, thus
-the allocation of the statements to processors is the same. The second
-dimension precises on a given processor at which logical date a statement
-instance has to be executed. Here, the statement @code{S1} is executed at
-day 2 on processor 1 while the statement @code{S3} is executed at day 1 onto
-the same processor. It follows this space/time mapping corresponds to the
-following target code (we added an additional variable to represent the
-local logical clocks):
-
-@example
-@group
-#pragma omp parallel sections
-@{
-   #pragma omp section
-   @{
-     // Logical processor 1
-     t = 1;
-     z = a * b;   // S3
-     t = 2;
-     x = a + b;   // S1
-   @}
-   #pragma omp section
-   @{
-     // Logical processor 2
-     t = 1;
-     y = c + d;   // S2
-   @}
-@}
-@end group
-@end example
-
-For the same reason as discussed for iteration domains
-(@pxref{Iteration Domain}), it is not possible to define a scattering for
-each statement instance, especially if the statement belongs to a
-(possibly parametric) loop. The iteration vector fully defines an
-instance of a given statement. Thus, a practical way to provide a scattering
-for each instance of a given statement is to use a @emph{function}
-that depends on the iteration vector. In this way the function may associate
-to each iteration vector a different scattering. We call these functions
-@strong{scattering functions}. Scattering functions are @emph{affine}
-functions of the outer loop counter and the global parameters.
-For instance, let us consider the following source code:
-
-@example
-@group
-for (i = 2; i <= 4; i++)
-  for (j = 2; j <= 4; j++)
-    P[i+j] += A[i] + B[j]; // S4
-@end group
-@end example
-
-@noindent The iteration domain of the statement @code{S4} is:
-
-
-@tex
-$$D _{S4} =  \{(i,j) \in Z^2 \; | \; 2 \leq i \leq 4 \land 2 \leq j \leq 4 \}.$$
-@end tex
-@ifnottex
-@example
-@group
-D_S4=  @{(i,j) in Z^2 | 2 <= i <= 4 && 2 <= j <= 4 @}.
-@end group
-@end example
-@end ifnottex
-
-@noindent If you are still not comfortable with the mathematical notation, it
-corresponds to the following graphical representation:
-
-@image{images/basic2,3cm}
-
-@noindent The list of the statement instances of @code{S4} (the integer
-points of its iteration domain) corresponds to the following iteration vectors:
-
-@example
-@group
-iteration vector
-     (2,2)
-     (2,3)
-     (2,4)
-     (3,2)
-     (3,3)
-     (3,4)
-     (4,2)
-     (4,3)
-     (4,4)
-@end group
-@end example
-
-@noindent Let us suppose we want to schedule the instances of the statement
-@code{S4} (the integer points of its iteration domain) using the following
-scheduling function:
-
-@tex
-@example
-@group
-$\theta_{S4}(i, j) = (j+2, 3*i+j)$
-@end group
-@end example
-@end tex
-
-@ifnottex
-@example
-@group
-T_S4(i,j) = (j+2,3*i+j)
-@end group
-@end example
-@end ifnottex
-
-@noindent We only need to apply the function to each iteration vector to find
-the logical date of each instance:
-
-@example
-@group
-iteration vector       logical date
-     (2,2)       -->       (4,8)
-     (2,3)       -->       (5,9)
-     (2,4)       -->       (6,10)
-     (3,2)       -->       (4,11)
-     (3,3)       -->       (5,12)
-     (3,4)       -->       (6,13)
-     (4,2)       -->       (4,14)
-     (4,3)       -->       (5,15)
-     (4,4)       -->       (6,16)
-@end group
-@end example
-
-The polyhedral model users do not have to take care about the generation of a
-target code that respects the scattering: the
-CLooG@footnote{@url{http://www.cloog.org}} tool is there to
-solve the problem quite easily. For the previous
-example, the target code would be the following (@code{t1} and @code{t2}
-correspond to the two dimensions of the logical date, the reader may
-take care that this code actually implements the scattering function):
-
-@example
-@group
-for (t1 = 4; t1 <= 6; t1++) @{
-  for (t2 = t1+4; t2 <= t1+10; t2++) @{
-    if ((-t1+t2+2)%3 == 0) @{
-      i = (-t1+t2+2)/3 ;
-      j = t1-2 ;
-      P[i+j] += A[i] + B[j]; // S4
-    @}
-  @}
-@}
-@end group
-@end example
-
-
-
-Obviously with such a twisted scheduling, it is hard to see the "meaning"
-of the transformation. To name any kind of program transformation as
-a magic spell ("tile", "fuse", "skew"...) is an old bad habit which is not
-relevant anymore in the polyhedral model: a scheduling may be an arbitrary
-complex sequence of basic-old-good transformations. Nevertheless it is most
-of the time quite easy to translate well known transformations to schedules.
-For instance, let us consider this new scheduling function:
-
-@tex
-@example
-@group
-$\theta_{S4}(i,j) = (j,i)$
-@end group
-@end example
-@end tex
-
-@ifnottex
-@example
-@group
-T_S4(i,j) = (j,i)
-@end group
-@end example
-@end ifnottex
-
-@noindent Using CLooG, we can generate the target code:
-
-@example
-@group
-for (t1 = 2; t1 <= 4; t1++) @{
-  for (t2 = 2; t2 <= 4; t2++) @{
-    i = t2;
-    j = t1;
-    P[i+j] += A[i] + B[j]; // S4
-  @}
-@}
-@end group
-@end example
-
-
-@noindent It is easy to see (and analyze) that it corresponds to a classical
-@emph{loop interchange} transformation.
-
-A very useful example of multi-dimensional scattering functions is
-the @strong{scheduling of the original program}.
-The method to compute it is quite simple (@pxref{Fea92}). The idea is to
-build an abstract syntax tree of the program and to read the scheduling for
-each statement. For instance, let us consider the following implementation of
-a Cholesky factorization:
-
-@example
-@group
-/* A Cholesky factorization kernel. */
-for (i=1;i<=N;i++) @{
-  for (j=1;j<=i-1;j++) @{
-    a[i][i] -= a[i][j] ;           // S1
-  @}
-  a[i][i] = sqrt(a[i][i]) ;        // S2
-  for (j=i+1;j<=N;j++) @{
-    for (k=1;k<=i-1;k++) @{
-      a[j][i] -= a[j][k]*a[i][k] ; // S3
-    @}
-    a[j][i] /= a[i][i] ;           // S4
-    @}
-  @}
-@}
-@end group
-@end example
-
-@noindent The corresponding abstract syntax tree is shown in the following
-figure. It directly gives the scattering functions (schedules) for all the
-statements of the program (just follow the paths).
-
-@image{images/tree,6cm}
-
-@tex
-$$

-                \theta _{S3}(i,j,k)  &$=  (0,i,2,j,0,k,0)$\cr
-                \theta _{S4}(i,j)    &$=  (0,i,2,j,1)$}$}

-T_S4(i,j)   = (0,i,2,j,1)
-@end group
-@end example
-@end ifnottex
-
-@noindent These schedules depend on the iterators and give for each instance
-of each statement a unique execution date. Using such scattering functions
-allows CLooG to re-generate the input code.
-

-@node Access Function
-@subsection Access Function
-
-Before applying any transformation, it is essential to deeply analyze both the
-original program and the transformation to ensure the transformation does not
-imply any modification of the original program semantics. In the polyhedral
-model, we are able to achieve
-an exact analysis when all the memory accesses are made through arrays
-(note that variables are a particular case of arrays since they are simply
-arrays with only one memory location) with affine subscripts that depend
-on outer loop counters and global parameters (note that @emph{subscripts}
-are sometimes called @emph{index} or @emph{accesses} in the literature).
-
-For instance let us consider the array access @code{A[2*i+j][j][i+N]}. It has
-three dimensions, each subscript dimension is an affine form of some outer loop
-iterarors (@code{i} and @code{j}) and global parameters (@code{N}) hence
-it corresponds to an acceptable array access to be analyzed in the
-polyhedral model.
-
-Each array access can target a different memory cell depending on the
-statement instance, i.e., depending on the iteration vector.
-Thus we use access functions (or subscript functions, or index functions, as you
-prefer to call it) depending on the iteration vector to describe an array
-access. In our example, the access function would be written
-@math{F_A(i, j) = (2*i+j, j, i+N)}.
-
-@noindent To easily manipulate the access function of any
-array @code{A}, we translate it to the matrix form:
-@math{F_A}(@emph{iteration vector})

-OK, now you have an idea about how we do represent a program part in the
-polyhedral model. You know the three main concepts, namely: domain, scattering
-and access. What can you do with this?! Well, pretty much anything related
-to code restructuring! The core idea will be to rely on the mathematical
-representation to extract useful information about your
-code (data reuse, parallelism...) and to generate a scattering
-to benefit from the properties you analysed.
-However, OpenScop's documentation is not the right
-place to learn at this (OpenScop is all about representation, not about
-manipulation). Probably it is the right time for you to
-have a look at:
-@itemize @bullet
-@item PoCC @url{http://pocc.sourceforge.net}
-@item Pluto @url{http://pluto-compiler.sourceforge.net}

-OpenScop provides an explicit polyhedral representation of a static control
-part. It has been designed by various polyhedral compilation tool writers from
-various institutions. It builds on previous popular polyhedral file and data
-structure formats (such as @emph{.cloog} and CLooG data structures) to provide
-a unique, extensible format to most polyhedral compilation tools. It
-is composed of two parts. The first part, the so-called 
-@emph{core part}, is devoted to the polyhedral representation of a SCoP.
-It contains what is strictly necessary to build a
-complete source-to-source framework in the polyhedral model and to output a
-semantically equivalent code for the SCoP, from analysis to code generation.
-The second part of the format, the so-called @emph{extension part},
-contains extensions to provide additional informations to some tools.

-@section Preliminary Example
-OpenScop is a specification for representing static control program parts in
-the polyhedral model. Thus, we can translate some code parts to an equivalent
-OpenScop representation. As an example, let us consider the
-following matrix-multiply kernel:
-
-@example
-#pragma scop
-if (N > 0) @{
-  for (i = 0; i < N; i++) @{
-    for (j = 0; j < N; j++) @{
-      C[i][j] = 0.0;
-      for (k = 0; k < N; k++)
-        C[i][j] = C[i][j] + A[i][k] * B[k][j];
-    @}
-  @}
-@}
-@end example
-
-The Clan@footnote{@url{http://www.lri.fr/~bastoul/development/clan/}}
-tool may be used to translate this code part to an OpenScop
-representation automatically. The @code{#pragma scop} is used here for
-Clan, but some other tool may not need it. Here is the result of the
-translation to an OpenScop textual representation.

-The @samp{Context} and the @samp{Statements} parts compose the
-@emph{core part}, i.e., what is strictly necessary to build
-a complete source to source framework based on OpenSCop:
-@itemize @bullet
-@item  @samp{Context} represents the global information of the SCoP. It
-       consists on the target language, the global constraints on the
-       parameters and optionally the parameter information which may be necessary
-       for the code generation process. The constraints on the parameters
-       are represented as a relation (@pxref{Context Domain Relation}).
-       The parameter information is optional. It is preceded by a
-       boolean which precises whether it is provided or not.
-       It is a generic information (@pxref{Generics}), a @code{strings}
-       (@pxref{Strings Generic}) for instance.
-@item  @samp{Statements} represents the information about the statements.
-       @samp{Nb_statements} is the number of statements in the SCoP,
-       i.e. the number of @samp{Statement} items in the @samp{Statement_list}.
-       @samp{Statement} represents the information on a given statement.
-       To each statement is associated a list of relations and,
-       optionaly, a body. The list of relations may include
-       one iteration domain (@pxref{Iteration Domain Relation}),
-       one scattering relation (@pxref{Scattering Relation})
-       and several access relations (@pxref{Access Relation}).
-       There is no mandatory ordering, but for consistency reason it would
-       be much appreciated that iteration domain comes first (if present)
-       then scattering (if present), then accesses (if present).
-       The statement body is an optional information. It is preceded by a
-       boolean which precises whether it is provided or not. 
-       It is a generic information (@pxref{Generics}), a @code{body}

-@emph{Relations} are the essence of the OpenScop format and contain the
-"polyhedral" information. They are used to describe either an iteration
-domain, or a context domain, or a scattering or a memory access.
-
-We use the relation term as a shortcut to denote a
-union of convex relations, each element of the union being described by a set of
-constraints in an extended PolyLib format (@pxref{Wil93}).
-The number of elements in the union is given by an integer on the first line,
-optionally followed by a comment starting with @samp{#}.
-This number of elements can be omitted when there is only one element.
-Each element in the union has the following syntax:
-
-@enumerate
-@item Some optional comment lines beginning with @samp{#}.
-@item A line with the type of the relation, possibly followed by comments.
-      The type can be one of the following:
-      @itemize @bullet
-      @item @code{UNDEFINED}: generic relation,
-      @item @code{CONTEXT}: for context information,
-      @item @code{DOMAIN}: for iteration domains,
-      @item @code{SCATTERING}: for scattering relation,
-      @item @code{READ}: for read accesses,
-      @item @code{WRITE}: for write accesses,
-      @item @code{MAY_WRITE}: for may-write accesses,
-      @end itemize
-@item A line with 6 numbers, possibly followed by comments:
-      @enumerate
-      @item the number of rows of the constraint matrix,
-      @item the number of columns of the constraint matrix,
-      @item the number of @emph{output dimensions},
-      @item the number of @emph{input dimension},
-      @item the number of @emph{local dimensions}
-            (existentially quantified dimensions),
-      @item the number of @emph{parameters}.
-      @end enumerate
-      The sum of the last four numbers should be equal to the number of columns
-      minus two. The remaining two columns are the equality/inequality
-      indicator and the constant term. The number of parameters should be the
-      same for all relations in the entire OpenScop file or data structure.
-@item The constraint rows. Each row corresponds to a constraint the
-      relation has to satisfy. Each row must be on a single line and is possibly
-      followed by comments. The constraint is an equality @math{p(x) = 0} if the
-      first element is 0, an inequality  @math{p(x) \geq 0} if the first element
-      is 1. The next elements are the coefficients of the output dimensions,
-      followed by coefficients of the input dimensions, the existentially
-      quantified dimensions and finally the parameters.
-      The last element is the constant term.
-@end enumerate

-This representation is the basis for several purposes. Examples for
-iteration domains (@pxref{Iteration Domain Relation}), context domains
-(@pxref{Context Domain Relation}), scattering
-relations (@pxref{Scattering Relation}) and

-@c %/**************************  ITERATION DOMAIN  ****************************
-@node Iteration Domain Relation
-@subsubsection Iteration Domain Relation
-
-Iteration domain represents the set of instances of the corresponding statement.
-OpenScop iteration domains are represented as relations with the following
-conventions:
-@itemize @bullet
-@item the type is @code{DOMAIN},
-@item there is 0 input dimension,
-@item loop iterators correspond to output dimensions.
-@end itemize
-
-@noindent For instance, assuming that @samp{i}, @samp{j} and @samp{k} are the loop
-iterators and @samp{M} and @samp{N} are the parameters, the domain defined by
-the following constraints :
-
-@tex
-$$
-\hbox{$ \cases{ -i     + M &$\geq 0$\cr
-                    -j + N &$\geq 0$\cr
-                 i + j - k &$\geq 0$}$}
-$$
-@end tex
-@ifnottex
-@example
-@group
-   -i + M >= 0
-   -j + N >= 0
-i + j - k >= 0
-@end group
-@end example
-@end ifnottex
-
-@noindent can be written in the input file as follows:
-
-@example
-@group
-# This is an iteration domain
-DOMAIN
-1 # Number of relations in the union
-3 7 3 0 0 2                  # 3 rows, 7 cols: 3 output dims and 2 params
-# e/i| i   j   k | M   N | 1
-   1  -1   0   0   1   0   0 #    -i + M >= 0
-   1   0  -1   0   0   1   0 #    -j + N >= 0
-   1   1   1  -1   0   0   0 # i + j - k >= 0
-@end group
-@end example
-
-@noindent Equivalently, it can be written in the following way as the number
-of relations in the union can be omitted if it is 1:
-
-@example
-@group
-# This is an iteration domain
-DOMAIN
-3 7 3 0 0 2                  # 3 rows, 7 cols: 3 output dims and 2 params
-# e/i| i   j   k | M   N | 1
-   1  -1   0   0   1   0   0 #    -i + M >= 0
-   1   0  -1   0   0   1   0 #    -j + N >= 0
-   1   1   1  -1   0   0   0 # i + j - k >= 0
-@end group
-@end example
-
-@noindent As an example for unions, let us consider the following pseudo-code:
-
-@example
-@group
-for (i = 1; i <= N; i++) @{
-  if ((i >= M) || (i <= 2*M))
-    S1(i);
-@}
-@end group
-@end example
-
-@noindent The iteration domain of @samp{S1} can be divided into two
-relations and written in the OpenScop file as follows:
-
-@example

-@subsubsection Access Relation
-
-Access relation maps an iteration domain to an array space.
-Each array accessed in the SCoP has a unique identification number.
-OpenScop relation information is represented as relations
-(@pxref{Relations}) with the following conventions:
-
-@itemize @bullet
-@item the type is one of the following:
-      @itemize @bullet
-      @item @code{READ}, for read accesses,
-      @item @code{WRITE}, for write accesses,
-      @item @code{MAY_WRITE}, for may write accesses,
-      @end itemize
-@item output dimensions correspond to the array identifier and dimensions,
-@item the first output dimension corresponds to the array identifier,
-@item the (i+1)th output dimension corresponds to the ith array dimension (i>1),
-@item loop iterators correspond to input dimensions.
-@end itemize
-
-As an example of a scattering relation and
-assuming that @samp{i}, @samp{j} and @samp{k} are the loop
-iterators and @samp{M} and @samp{N} are the parameters, let us consider
-the array access @code{A[2*i+j][j][i+N]} (the identifier of @code{A} is 42),
-and let us suppose this is a read access. Its representation would be the
-following:
-
-@example
-@group
-# A read access relation
-READ
-# 4 rows, 11 columns: 4 array dimensions, 3 iterators, 2 parameters
-4 11 4 3 0 2
-# e/i|Arr [1] [2] [3]| i   j   k | M   N | 1
-   0  -1   0   0   0   0   0   0   0   0  42   # A
-   0   0  -1   0   0   2   1   0   0   0   0   #  [2*i+j]
-   0   0   0  -1   0   0   1   0   0   0   0   #         [j]
-   0   0   0   0  -1   1   0   0   0   1   0   #            [i+N]
-@end group
-@end example
-
-To understand this representation, consider that OpenScop accesses
-are general memory accesses and not array accesses. The memory is
-seen as a big array @code{Mem} while usual array names correspond to
-the first dimension. Hence our example translates to @code{Mem[42][2*i+j][j][i+N]}.
-
-Unions of access relations are allowed. In this case, each union part must
-refer at the same array identifier, and the number of dimensions must be
-consistent.

-@emph{Generics} represent any elaborated non-polyhedral information in the
-OpenScop format. They are used to represent the parameter information, the
-statement body information as well as the extensions. Each generic information
-is delimited using XML-like tags corresponding to its URI (Unique Resource
-Identifier), For instance, if the generic has the URI @code{foo}, the begin
-tag is @code{<foo>} and the end tag is @code{</foo>}).
-
-Two generics, namely @code{strings} (@pxref{Strings Generic}) and
-@code{body} (@pxref{Body Generic}) are part of the OpenScop
-specification to provide the minimum, stricly necessary information to
-build a complete source-to-source polyhedral framework based on OpenScop.
-However, generics can be basically @emph{anything} as long as they are
-properly delimited. OpenScop implementations will simply ignore
-non-supported generics and warn the user with the mention of the
-non-supported URIs. Support of new generics will be added throught the
-extension mechanism.

-
-The purpose of the @code{strings} generic is to represent a list of

-Strings             ::= _String String_list  | (void)

-The OpenScop specification offers a small set of C data structures devoted to
-represent a SCoP in memory in a convenient way. Using them in some tool or
-library may greatly facilitate its interaction with other tools or libraries
-which rely on this representation as well. Every field may not be useful for
-a given tool or library. A general rule for all the data structure is
-that a @code{NULL} pointer or a -1 integer value means the information is
-not present. Contrary to engineering time, memory is cheap today, so it's much
-probably not a big deal that some fields are left empty. Every field may not
-be enough for a given tool or library. In this case it is much recommended
-to provide a new extension which may be reused by other users
-(@pxref{Extensions}).
-
-Each tool or library may have its own implementation of the OpenScop
-data structures. The type names should not be the same as those provided
-as an example here (they correspond to the OpenScop Library implementation).
-The names of the fields, and their ordering, should however be the same. In this
-way, the interaction between tools and libraries should be as simple as a cast.
-
-Before reading at the OpenScop data structures, it is much recommended to
-read at the OpenScop file format description, as it is quite close to this
-representation (@pxref{OpenScop File Format Specification}).

-@section Extensions
-
-The core part of the OpenScop representation embeds what is strictly
-necessary to build a complete source-to-source polyhedral framework.
-However it may not be enough. Hence, OpenScop offers a very flexible
-extension part. Actually, the only constraint to build an extension is
-to request the OpenScop maintainer for a unique extension name: its URI
-(ask the maintainer through the OpenScop mailing list
-@email{openscop-development@@googlegroups.com}).
-
-The policy to support extensions is the following and is pretty simple: an
-OpenScop implementation is not required to support any extension. If it
-is processing an OpenScop file or data structure which contains an
-extension which is not supported, it must (1) warn the user with the 
-mention of the URI of the non-supported extension
-and (2) ignore this extension.
-
-Extensions in an OpenScop file are provided after the core part, without
-any specific order. Each extension is delimited using
-XML-like tags corresponding to its URI (e.g., if the extension has the URI
-@code{foo}, the begin tag is @code{<foo>} and the end tag is @code{</foo>}).
-There is no specification or preferred way to write the extension body.
-Extensions in an OpenScop data structure must be accessible through one
-pointer. This pointer will be stored in the @code{data} field of an
-@code{osl_generic_t} container (@pxref{osl_generic_t}). There must be only
-one extension with the same URI in an OpenScop file or data structure.
-
-Extension writers may write a short documentation about their extension to
-be added to this document. For consistency reason, this
-documentation should comply to the documentation of the
-@code{comment} option (@pxref{Comment Extension}). To describe the
-file format, it is allowed to reuse the existing rules and terminals
-present in the OpenScop file format description without defining them
-(@pxref{OpenScop File Format Specification}). By sending a
-documentation, you accept it to be added to this document. In
-particular, the sender fully accepts the license and copyright notice.

-
-The OpenScop Library, or OSL for short, is an example implementation of the
-OpenScop specification. Its API is not part of the OpenScop specification. 
-It offers basic functionalities to manipulate the OpenScop data structures
-(allocate, free, copy, dump, etc.) and file format (read, print, etc.).
-The OpenScop Library is @emph{not} a polyhedral library. OpenScop is an
-exchange format, and the OpenScop Library reflects this. 
-
-It is a Free Software using the 3-clause BSD License.
-Programmers should feel free to use
-it or copy/paste its code in any project, Open Source or not@footnote{Closed
-source projects should consider to provide some OpenScop file input
-and output, so they can be incorporated to any OpenScop-based tool chain.}.

-@section Precision
-
-The OpenScop specification does not impose a specific type for the
-constraint matrix elements. For a maximum flexibility, the OpenScop Library
-offers an hybrid precision implementation. It supports 32 bits, 64 bits and
-multiple precision (relying on GNU GMP) relations transparently. At relation
-allocation time, users have two ways to set the precision. The first way is
-to call an allocation function with a precision parameter. The second way is
-to rely on the environment variable @code{OSL_PRECISION}.
-The accepted values for this variable are @code{32} for 32 bits precision,
-@code{64} for 64 bits precision and @code{0} for multiple precision. When this
-variable is set, its value becomes the default precision for relation elements.
-For instance, to ensure the OpenScop Library will use 64 bits precision
-by default, the user may set: 
-@example
-export OSL_PRECISION=64
-@end example
-@noindent if his shell is, e.g., bash or
-@example
-setenv OSL_PRECISION 64
-@end example
-@noindent if his shell is, e.g., tcsh. The user should ad this line to
-his .bashrc or .tcshrc (or whatever convenient file) to make this
-setting permanent. 
-
-@node Base Functions
-@section Base Functions
-
-The OpenScop Library provides, for each OpenScop data structure,
-a set of functions devoted to basic manipulation, conversion
-from file format to data structures and from data structures to
-file format. The naming convention is consistent for all data
-structures. Hence, the function prototypes differ only with the
-name of the data structure. In the following, we will use the
-generic term of @emph{structure} to refer at any OpenScop
-data structure. For instance the
-@code{osl_}@emph{structure}@code{_malloc()} function is a
-generic name can be instantiated to
-@code{osl_relation_malloc()} or
-@code{osl_statement_malloc()} etc.
-
-We present in this documentation only
-the main functions. Many other utility functions are provided
-to ease OpenScop format manipulation. The reader is invited to
-refer at the technical documentation to learn everything about the
-OpenScop Library.

-@node Dumping
-@subsection Dumping: osl_@emph{structure}_dump and idump 
-
-@example
-@group
-void osl_@emph{structure}_dump(FILE * output, osl_@emph{structure}_p s);
-void osl_@emph{structure}_idump(FILE * output, osl_@emph{structure}_p s, int i);
-@end group
-@end example
-
-@noindent Each OpenScop data structure has a dumping functions
-as shown above. Dumping means writing down the content of the data
-structure pointed by @code{s} (and its fields recursively)
-in a textual form to the
-@code{output} file (the file, possibly @code{stdout}, has to be open
-for writing). The textual form is not the OpenScop file format but
-another representation closer to the internal representation in
-memory and mainly intended for debugging purpose. The @code{idump}
-function has an additional integer parameter which corresponds to
-an indentation level.
-
-@node Printing
-@subsection Printing: osl_@emph{structure}_print
-
-@example
-@group
-void osl_@emph{structure}_print(FILE * output, osl_@emph{structure}_p s);
-@end group
-@end example
-
-@noindent Each OpenScop data structure has a pretty printing function
-as shown above. It prints the content of the data
-structure pointed by @code{s} (and its fields recursively)
-according to the OpenScop file format
-(@pxref{OpenScop File Format Specification}) to the
-@code{output} file (the file, possibly @code{stdout}, has to be open
-for writing).
-
-@node Reading
-@subsection Reading: osl_@emph{structure}_read
-
-@example
-@group
-osl_@emph{structure}_p osl_@emph{structure}_read(FILE * input);
-@end group
-@end example
-
-@noindent Each OpenScop data structure has a reading function
-as shown above. It reads the content of an OpenScop
-data structure written according to the OpenScop file format 
-(@pxref{OpenScop File Format Specification}) from 
-the @code{input} file (the file, possibly @code{stdin}, has to be open
-for reading). It returns a pointer to a freshly allocated 
-@code{osl_@emph{structure}_t} structure containing the
-information.
-
-@node Allocating
-@subsection Allocating: osl_@emph{structure}_malloc
-
-@example
-@group
-osl_@emph{structure}_p osl_@emph{structure}_malloc();
-@end group
-@end example
-
-@noindent Each OpenScop data structure has a memory allocation function
-as shown above (except one see below). It allocates the memory to store
-the corresponding data structure, it initializes the pointer fields to
-@code{NULL} and the integer fields to @code{OSL_UNDEFINED}
-(@code{-1}) and it returns a pointer to the allocated space.
-
-An exception to this base description is the
-@code{osl_relation_malloc()} function which requires two
-parameters: the number of rows and columns of the constraint
-matrix (@pxref{Relations}):
-
-@example
-@group
-osl_relation_p osl_relation_malloc(int nb_rows, int nb_columns);
-@end group
-@end example
-
-@noindent The precision of the relation elements will depend on the
-@code{OSL_PRECISION} environment variable (@pxref{Precision}) if it is set,
-or the maximum available precision if it is not set. Another allocation
-function is provided to explicitly set a given precision:
-
-@example
-@group
-osl_relation_p osl_relation_pmalloc(int precision,
-                                    int nb_rows, int nb_columns);
-@end group
-@end example
-
-@noindent The @code{precision} field may take the following values:
-@itemize @bullet
-@item @code{OSL_PRECISION_SP} for 32 bits precision,
-@item @code{OSL_PRECISION_DP} for 64 bits precision,
-@item @code{OSL_PRECISION_MP} for multiple precision,
-@end itemize
-
-@node Deallocating
-@subsection Deallocating: osl_@emph{structure}_free
-
-@example
-@group
-void osl_@emph{structure}_free(osl_@emph{structure}_p s);
-@end group
-@end example
-
-@noindent Each OpenScop data structure has a memory deallocation function
-as shown above. It recursively frees the memory allocated for the
-structure pointed by @code{s}, i.e., internal structures are also freed.
-
-@node Cloning
-@subsection Cloning: osl_@emph{structure}_clone
-
-@example
-@group
-osl_@emph{structure}_p osl_@emph{structure}_clone(osl_@emph{structure}_p s);
-@end group
-@end example
-
-@noindent Each OpenScop data structure has a clone function
-as shown above. It recursively copies the content of the
-structure pointed by @code{s}, i.e., internal structures are also copied.
-It returns a pointer to the clone of the structure pointed by @code{s}.
-
-@node Testing
-@subsection Testing: osl_@emph{structure}_equal
-
-@example
-@group
-int osl_@emph{structure}_equal(osl_@emph{structure}_p s1, osl_@emph{structure}_p s2);
-@end group
-@end example
-
-@noindent Each OpenScop data structure has a testing function
-as shown above. It checks whether two pointers are referring to equivalent
-structures (either by pointing to the same structure or to different
-structures which contain the same information). It returns 1 if the
-pointed structures are equivalent, 0 otherwise. This test is
-@emph{content-based} and is intended for debugging purpose. It is not
-(and will never be) able to state, e.g., that two relations with
-different constraint matrices are actually representing the same relation.

-
-@node Example of OpenScop Library Utilization
-@section Example of OpenScop Library Utilization
-Here is a basic example showing how it is possible to use the
-OpenScop Library, assuming that a standard installation has been done.
-The following C program reads an OpenScop file from the standard
-input and dumps the content of the data structures to the standard output.
-
-@example
-/* example.c */
-# include <stdio.h>
-# include <osl/osl.h>
-
-int main() @{
-  osl_scop_p scop;
-
-  // Read the OpenScop file.
-  scop = osl_scop_read(stdin);
-
-  // Dump the content of the scop data structure.
-  osl_scop_dump(stdout, scop);
-
-  // Save the planet.
-  osl_scop_free(scop);
-
-  return 0;
-@}
-@end example
-
-@noindent The compilation command could be:
-@example
-gcc example.c -losl -o example
-@end example
-@noindent A calling command with the input file test.scop could be:
-@example
-more test.scop | ./example
-@end example

-
-@node Requirements
-@subsection Requirements
-
-The OpenScop Library is a stand-alone library. For a basic use,
-it does not need any additional tool or library. Anyway, to be able to
-work in conjunction with other tools that manipulate multiple precision
-numbers, the GNU GMP library can be used as an option.
-
-@menu
-* GMP Library::
-@end menu
-
-
-@node GMP Library
-@subsubsection GMP Library (optional)
-
-To be able to deal with insanely large coefficient, the user will need to
-install the GNU Multiple Precision Library (GMP for short) version 4.2.2
-or above@footnote{@code{http://www.swox.com/gmp}}.
-The user can compile it by typing the following commands on the GMP root
-directory:
-
-@itemize @bullet
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-The GMP default installation is @code{/usr/local}. This directory may
-not be inside the user's library path. To fix the problem, the user should set
-@example
-export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
-@end example
-@noindent if your shell is, e.g., bash or
-@example
-setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/usr/local/lib
-@end example
-@noindent if your shell is, e.g., tcsh. Add the line to your .bashrc or .tcshrc (or
-whatever convenient file) to make this change permanent. Another solution
-is to ask GMP to install in the standard path by using the prefix
-option of the configure script:
-@samp{./configure --prefix=/usr}.
-
-The OpenScop Library has to be built using the GMP library by specifying
-the convenient configure script options to buid the GMP version
-(@pxref{Optional Features}).
-
-
-@node Installation Instructions
-@subsection Installation Instructions
-
-Once downloaded and unpacked
-(e.g. using the @samp{tar -zxvf openscop-@value{LIB_VERSION}.tar.gz} command),
-you can compile the OpenScop Library by typing the following commands
-on the OpenScop Library's root directory:
-
-@itemize @bullet
-@item @code{./autogen.sh}
-@item @code{./configure}
-@item @code{make}
-@item And as root: @code{make install}
-@end itemize
-
-The program binaries and object files can be removed from the
-source code directory by typing @code{make clean}. To also remove the
-files that the @code{configure} script created (so you can compile the
-package for a different kind of computer) type @code{make distclean}.
-
-@node Optional Features
-@subsection Optional Features
-The @code{configure} shell script attempts to guess correct values for
-various system-dependent variables and user options used during compilation.
-It uses those values to create the @code{Makefile}. Various user options
-are provided by the OpenScop Library's configure script. They are summarized in the
-following list and may be printed by typing @code{./configure --help} in the
-OpenScop Library top-level directory.
-
-@itemize @bullet
-@item By default, the installation directory is @code{/usr/local}:
-@code{make install} will install the package's files in
-@code{/usr/local/bin}, @code{/usr/local/lib} and @code{/usr/local/include}.
-The user can specify an installation prefix other than @code{/usr/local} by
-giving @code{configure} the option @code{--prefix=PATH}.
-
-@item By default, The OpenScop Library is built in 64bits version.
-If the user gives to @code{configure} the option
-@code{--enable-int-version}, the 32bits version of the OpenScop Library
-will be compiled. In the same way, the option @code{--enable-mp-version}
-has to be used to build the multiple precision version.
-
-@item By default, @code{configure} will look for the GMP library
-(necessary to build the multiple precision version) in standard
-locations. If necessary, the user can specify the GMP path by giving
-@code{configure} the option @code{--with-gmp=PATH}.
-@end itemize
-
-@node Uninstallation
-@subsection Uninstallation
-The user can easily remove the OpenScop Library from his system
-by typing (as root if necessary) from the OpenScop Library top-level
-directory
-@code{make uninstall}.
-
-@c %  **************************** DOCUMENTATION ******************************
-@node Documentation
-@section Documentation
-The OpenScop Library distribution provides several sources of documentation.
-First, the source code itself is as documented as much as possible.
-The code comments use the Doxygen technical documentation system.
-The user may install
-Doxygen@footnote{@code{http://www.stack.nl/~dimitri/doxygen}} to automatically
-generate a technical documentation by typing @code{make doc} or
-@code{doxygen ./autoconf/Doxyfile} at the OpenScop Library
-top-level directory after running the configure script
-(@pxref{Installation Instructions}). Doxygen will generate
-documentation sources (in HTML, LaTeX and man) in the @code{doc/source}
-directory of the OpenScop Library distribution.
-
-The Texinfo source of the present document is also provided in the @code{doc}
-directory. The user can build it in either PDF format
-(by typing @code{texi2pdf openscop.texi}) or HTML format
-(by typing @code{makeinfo --html openscop.texi}, using @code{--no-split}
-option to generate a single HTML file) or info format
-(by typing @code{makeinfo openscop.texi}).

-@node Copyright Issue 
-@subsection Copyright Issue
-
-The OpenScop Library is an Open Source project and you should feel free to
-contribute by adding functionalities (in particular extensions), correcting
-bugs or improving documentation. However, for painful administrative reasons,
-the copyright of the core part (everything except extensions) should not be
-impacted by your work. Hence, if you are doing a significant contribution to
-the main part, the OpenScop Library maintainer may ask you for an agreement
-about this copyright. If you plan to do such a significant contribution, it
-may be wise to discuss this issue with the maintainer first. Extensions
-may include developer's own copyright.
-
-@node Repository 
-@subsection Repository
-
-The main repository of the OpenScop Library is
-@url{http://repo.or.cz/w/openscop.git}. Developers may ask the OpenScop Library
-maintainer to open them a write access to this repository. Only the maintainer
-should ever change the @code{master} branch. Developers should work on their
-own branches. To avoid any problem developers should use the @emph{fork}
-functionality of the repository.
-
-@node Coding Style 
-@subsection Coding Style  
-
-The OpenScop Library is written in C using an object oriented style. Each
-important data structure (e.g., @code{struct foo}) has its own header file
-(@code{include/osl/foo.h}) where lies the definition of
-the data structure, the two typedefs for the data structure (one for the
-structure, @code{osl_foo_t}, and one for a pointer
-to the structure, @code{osl_foo_p}), the prototypes of the various
-functions related to this data structure, all named using the
-prefix "@code{osl_foo_}". The source code of the functions is provided in a
-separated C file (@code{source/foo.c}).
-  
-Utility functions independent from the main data structures may be placed in
-separate source files (e.g., definition in @code{include/osl/util.h}
-and code in @code{source/util.c}). Tool-wide preprocessor directives are
-placed in @code{include/osl/macros.h}, macros are prefixed with
-"@code{OSL_}".
-
-The core code itself has to be written according to the Google C++ Coding Style:
-@url{http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml} (for
-what can apply to C), plus the naming conventions discussed above with
-highest priority. The extension parts must only respect the naming convention,
-but a consistent coding style is much appreciated.
-
-@node Extension Development
-@subsection Extension Development
-
-It's fairly easy to integrate a new extension to OpenScop and the OpenScop
-Library. Developing a new extension is very much like adding a new "object":
-it requires writing a data structure for the extension data and the 7 base
-functions to manage this extension. Here is how developers should proceed
-to add an extension called @code{foo} (beware that the naming convention is
-strict):
-
-@enumerate
-@item Send the name @code{foo} to the maintainer to ensure it is unique and
-      hence can be used as an URI. The name (one single
-      word, or words separated with underscores "_") should be
-      suggested by the extension developers to the OpenScop development
-      mailing list @email{openscop-development@@googlegroups.com}). It
-      should not correspond to an existing structure name
-      (see @code{include/osl/osl.h} for the list). The
-      maintainer will update @code{include/osl/osl.h} in the development
-      version accordingly.
-@item Look at the @code{comment} extension. The @code{comment} extension
-      (@pxref{Comment Extension}) has been written to be used as a basic
-      example for extension developers. Having a look at
-      @code{include/osl/extensions/comment.h} and
-      @code{source/extensions/comment.c} will be a great help to do it right.
-@item Create the extension data structure: it is necessary that the
-      extension data can be accessible through only one pointer.
-@item Code the 7 base functions for the extension. Any extension must provide
-      this set of functions (naming convention apply only if the
-      extension is planed to be integrated to the OpenScop Library
-      default extensions):
-      @itemize @bullet
-      @item @code{osl_foo_idump} (@pxref{Dumping}) 
-      @item @code{osl_foo_sprint} has the following prototype:
-@example
-@group
-char * osl_@emph{structure}_sprint(osl_@emph{structure}_p s);
-@end group
-@end example
-           It corresponds to the pretty printing functions of the core
-           data structures (@pxref{Printing}) with the
-           difference that the OpenScop textual representation is written
-           to a string (returned by the function) instead of a file.
-      @item @code{osl_foo_sread} has the following prototype:
-@example
-@group
-osl_@emph{structure}_p osl_@emph{structure}_sread(char ** string);
-@end group
-@end example
-           It corresponds to the reading functions of the core
-           data structures (@pxref{Reading}) with the
-           difference that the OpenScop textual representation is read
-           from a string (provided as a parameter) instead of a file.
-           The address of the string to read is passed as a parameter and
-           is updated to point immediately after what has been actually read.
-      @item @code{osl_foo_malloc} (@pxref{Allocating}) 
-      @item @code{osl_foo_free} (@pxref{Deallocating}) 
-      @item @code{osl_foo_clone} (@pxref{Cloning}) 
-      @item @code{osl_foo_equal} (@pxref{Testing}) 
-      @end itemize
-@item Code the other functions you need!
-@end enumerate
-
-Now let us consider two scenarios.
-
-First scenario, the extension is external and is
-not planned to be integrated to the OpenScop Library. In this case you are
-all set. Simply generate an @code{osl_interface_t} for your
-extension and have a look at the function
-@code{osl_scop_register_extension()} which is devoted to register
-a new extension interface to an existing @code{osl_scop_t}.
-
-Second scenario, the extension will integrate the set of default
-OpenScop Library extensions (the best solution to share it to other
-potential users). In this case, a few additional
-things have to be done:
-@enumerate
-@item Create the extension header
-      @code{include/osl/extensions/foo.h} to store the extension
-      structure and function prototypes and the
-      extension source file @code{source/extensions/foo.c} for the code
-      of the functions.
-@item Add the documentation for the extension to the texinfo source of
-      this document (in @code{doc/openscop.texi}), following the example
-      of the @code{comment} documentation (@pxref{Comment Extension}).
-@item Integrate the extension by adding the @code{extensions/foo.c} entry
-      to the @code{libosl_la_SOURCES} in the @code{source/Makefile.am}
-      file, the @code{osl/foo.h} entry to the
-      @code{nobase_pkginclude_HEADERS} and add the corresponding
-      @code{#include <osl/extensions/foo.h>} in the
-      @code{include/scop.h.in} file.
-@item Add the new extension in the
-      @code{osl_interface_get_default_registry()} function.
-@item You are done! Prepare a single commit or patch corresponding to the
-      integration of the new extension and ask the maintainer to merge it
-      to the master branch.

-/**
- * The osl_relation_t structure stores a union of relations. It is a
- * NULL-terminated linked list of relations. Each relation is described
- * using a matrix where each row represents a linear constraint. The entries
- * of each row are organised in the following order:
- * - An equality/inequality tag: 0 means the row corresponds to an
- *   equality constraint == 0, 1 means it is an inequality >= 0.
- * - The coefficients of the output dimensions.
- * - The coefficients of the input dimensions (0 for a set).
- * - The coefficients of the local (existentially quantified) dimensions.
- * - The coefficients of the parameters.
- * - The coefficient of the constant.
- * Thus we have the following invariant: nb_columns =
- * 1 + nb_output_dims + nb_input_dims + dims + nb_parameters + 1.
- * Moreover we use the following conventions:
- * - Sets (e.g., iteration domains) are the images of relations with a
- *   zero-dimensional domain, hence the number of input dimensions is 0.
- * - The first output dimension of any access relations corresponds to
- *   the name of the array.
- * The type field may provide some semantics about the relation, it may be:
- * - Undefined : OSL_UNDEFINED,
- * - An iteration domain : OSL_TYPE_DOMAIN,
- * - A scattering relation : OSL_TYPE_SCATTERING,
- * - An access relation : OSL_TYPE_ACCESS.
