+ **************************************************************************
+ * 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.

+ **************************************************************************
+ *
+ * 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.
