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: + * -DROPT (default: Not defined) + * As an approximation to what an average C + * programmer might do, the "register" storage class + * is applied (if enabled by -DROPT) + * - 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. + * + ************************************************************************* + * + * 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.
