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. * *************************************************************************** * * History: This version C/2.1 has been made for two reasons: * * 1) There is an obvious need for a common C version of * Dhrystone, since C is at present the most popular system * programming language for the class of processors * (microcomputers, minicomputers) where Dhrystone is used most. * There should be, as far as possible, only one C version of * Dhrystone such that results can be compared without * restrictions. 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. * -DICACHEON (default: Not defined) * Adjust performace by conditionally compiling * these i960jx CACHE paramaters. * -DICACHEOFF * -DDCACHEON (default: Not defined) * -DDCACHEOFF * * NOTE: Galileo-5 Board Frequency is set to 33Mhz in the * file jx-timer.c. If the operating frequency is * changed by replacing the crystal, then this #define * must also be changed. * *************************************************************************** * * Compilation model and measurement (IMPORTANT): * * This C version of Dhrystone consists of four 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) * - jx-timer.c (containing the code to access the i960jx timer) * * The following "ground rules" apply for measurements: * - 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. * * Example Intel 960jx compile syntax for Galileo-5. * * ic960 -AJA -Tgal5 -O2 -DREG=register dhry_1.c dhry_2.c jx-timer.c * ************************************************************************** * * 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.
