- * 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.
