* "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, E STE 35
* Postfach 3240
* 8520 Erlangen
* Germany (West)
* Phone: [xxx-49]-9131-7-20330
* (8-17 Central European Time)
* Usenet: ..!mcvax!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.
*
