**************************************************************************
* DHRYSTONE 2.1 BENCHMARK PC VERSION
**************************************************************************
*
* "DHRYSTONE" Benchmark Program
* -----------------------------
*
* Version: C, Version 2.1
*
* File: dhry.h (part 1 of 3)
*
* Date: May 25, 1988
*
* Author: Reinhold P. Weicker
* Siemens AG, AUT E 51
* Postfach 3220
* 8520 Erlangen
* Germany (West)
* Phone: [+49]-9131-7-20330
* (8-17 Central European Time)
* Usenet: ..!mcsun!unido!estevax!weicker
*
* Original Version (in Ada) published in
* "Communications of the ACM" vol. 27., no. 10 (Oct. 1984),
* pp. 1013 - 1030, together with the statistics
* on which the distribution of statements etc. is based.
*
* In this C version, the following C library functions are used:
* - strcpy, strcmp (inside the measurement loop)
* - printf, scanf (outside the measurement loop)
* In addition, Berkeley UNIX system calls "times ()" or "time ()"
* are used for execution time measurement. For measurements
* on other systems, these calls have to be changed.
*
* Collection of Results:
* Reinhold Weicker (address see above) and
*
* Rick Richardson
* PC Research. Inc.
* 94 Apple Orchard Drive
* Tinton Falls, NJ 07724
* Phone: (201) 389-8963 (9-17 EST)
* Usenet: ...!uunet!pcrat!rick
*
* Please send results to Rick Richardson and/or Reinhold Weicker.
* Complete information should be given on hardware and software used.
* Hardware information includes: Machine type, CPU, type and size
* of caches; for microprocessors: clock frequency, memory speed
* (number of wait states).
* Software information includes: Compiler (and runtime library)
* manufacturer and version, compilation switches, OS version.
* The Operating System version may give an indication about the
* compiler; Dhrystone itself performs no OS calls in the measurement
* loop.
*
* The complete output generated by the program should be mailed
* such that at least some checks for correctness can be made.
*
**************************************************************************
*
* This version has changes made by Roy Longbottom to conform to a common
* format for a series of standard benchmarks for PCs:
*
* Running time greater than 5 seconds due to inaccuracy of the PC clock.
*
* Automatic adjustment of run time, no manually inserted parameters.
*
* Initial display of calibration times to confirm linearity.
*
* Display of results within one screen (or at a slow speed as the test
* progresses) so that it can be seen to have run successfully.
*
* Facilities to type in details of system used etc.
*
* All results and details appended to a results file.
*
*
* Roy Longbottom
* 101323.2241@compuserve.com
*
**************************************************************************
*
* For details of history, changes, other defines, benchmark construction
* statistics see official versions from ftp.nosc.mil/pub/aburto where
* the latest table of results (dhry.tbl) are available. See also
* netlib@ornl.gov
*
**************************************************************************
*
* Defines: The following "Defines" are possible:
* -DREG=register (default: Not defined)
* As an approximation to what an average C programmer
* might do, the "register" storage class is applied
* (if enabled by -DREG=register)
* - for local variables, if they are used (dynamically)
* five or more times
* - for parameters if they are used (dynamically)
* six or more times
* Note that an optimal "register" strategy is
* compiler-dependent, and that "register" declarations
* do not necessarily lead to faster execution.
* -DNOSTRUCTASSIGN (default: Not defined)
* Define if the C compiler does not support
* assignment of structures.
* -DNOENUMS (default: Not defined)
* Define if the C compiler does not support
* enumeration types.
***************************************************************************
*
* Compilation model and measurement (IMPORTANT):
*
* This C version of Dhrystone consists of three files:
* - dhry.h (this file, containing global definitions and comments)
* - dhry_1.c (containing the code corresponding to Ada package Pack_1)
* - dhry_2.c (containing the code corresponding to Ada package Pack_2)
*
* The following "ground rules" apply for measurements:
* - Separate compilation
* - No procedure merging
* - Otherwise, compiler optimizations are allowed but should be indicated
* - Default results are those without register declarations
* See the companion paper "Rationale for Dhrystone Version 2" for a more
* detailed discussion of these ground rules.
*
* For 16-Bit processors (e.g. 80186, 80286), times for all compilation
* models ("small", "medium", "large" etc.) should be given if possible,
* together with a definition of these models for the compiler system used.
