For measurements - * on other systems, these calls have to be changed. - * - * Collection of Results: - * Reinhold Weicker (address see above) and - * - * Rick Richardson - * PC Research.

In the past, the C versions distributed - * by Rick Richardson (Version 1.1) and by Reinhold Weicker - * had small (though not significant) differences. - * - * 2) As far as it is possible without changes to the Dhrystone - * statistics, optimizing compilers should be prevented from - * removing significant statements. - * - * This C version has been developed in cooperation with - * Rick Richardson (Tinton Falls, NJ), it incorporates many - * ideas from the "Version 1.1" distributed previously by - * him over the UNIX network Usenet. - * I also thank Chaim Benedelac (National Semiconductor), - * David Ditzel (SUN), Earl Killian and John Mashey (MIPS), - * Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley) - * for their help with comments on earlier versions of the - * benchmark. - * - * Changes: In the initialization part, this version follows mostly - * Rick Richardson's version distributed via Usenet, not the - * version distributed earlier via floppy disk by Reinhold Weicker. - * As a concession to older compilers, names have been made - * unique within the first 8 characters. - * Inside the measurement loop, this version follows the - * version previously distributed by Reinhold Weicker. - * - * At several places in the benchmark, code has been added, - * but within the measurement loop only in branches that - * are not executed. The intention is that optimizing compilers - * should be prevented from moving code out of the measurement - * loop, or from removing code altogether. Since the statements - * that are executed within the measurement loop have NOT been - * changed, the numbers defining the "Dhrystone distribution" - * (distribution of statements, operand types and locality) - * still hold. Except for sophisticated optimizing compilers, - * execution times for this version should be the same as - * for previous versions. - * - * Since it has proven difficult to subtract the time for the - * measurement loop overhead in a correct way, the loop check - * has been made a part of the benchmark. This does have - * an impact - though a very minor one - on the distribution - * statistics which have been updated for this version. - * - * All changes within the measurement loop are described - * and discussed in the companion paper "Rationale for - * Dhrystone version 2". - * - * Because of the self-imposed limitation that the order and - * distribution of the executed statements should not be - * changed, there are still cases where optimizing compilers - * may not generate code for some statements. To a certain - * degree, this is unavoidable for small synthetic benchmarks. - * Users of the benchmark are advised to check code listings - * whether code is generated for all statements of Dhrystone. - * - * Version 2.1 is identical to version 2.0 distributed via - * the UNIX network Usenet in March 1988 except that it corrects - * some minor deficiencies that were found by users of version 2.0. - * The only change within the measurement loop is that a - * non-executed "else" part was added to the "if" statement in - * Func_3, and a non-executed "else" part removed from Proc_3. - * - *************************************************************************** - * - * 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. - * -DTIMES (default) - * -DTIME - * The "times" function of UNIX (returning process times) - * or the "time" function (returning wallclock time) - * is used for measurement. - * For single user machines, "time ()" is adequate. For - * multi-user machines where you cannot get single-user - * access, use the "times ()" function. If you have - * neither, use a stopwatch in the dead of night. - * "printf"s are provided marking the points "Start Timer" - * and "Stop Timer". DO NOT use the UNIX "time(1)" - * command, as this will measure the total time to - * run this program, which will (erroneously) include - * the time to allocate storage (malloc) and to perform - * the initialization. - * -DHZ=nnn - * In Berkeley UNIX, the function "times" returns process - * time in 1/HZ seconds, with HZ = 60 for most systems. - * CHECK YOUR SYSTEM DESCRIPTION BEFORE YOU JUST APPLY - * A VALUE. - * - *************************************************************************** - * - * 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. - * - ************************************************************************** - * - * Dhrystone (C version) statistics: - * - * [Comment from the first distribution, updated for version 2. - * Note that because of language differences, the numbers are slightly - * different from the Ada version.] - * - * The following program contains statements of a high level programming - * language (here: C) in a distribution considered representative: - * - * assignments 52 (51.0 %) - * control statements 33 (32.4 %) - * procedure, function calls 17 (16.7 %) - * - * 103 statements are dynamically executed.
