- * -----------------------------
- *
- * Version: C, Version 2.1
- *
- * File: dhry.h (part 1 of 3)
- *
- * Date: May 25, 1988
- *
- * Author: Reinhold P. Weicker
- * Siemens Nixdorf Inf. Syst.
- * STM OS 32
- * Otto-Hahn-Ring 6
- * W-8000 Muenchen 83
- * Germany
- * Phone: [+49]-89-636-42436
- * (8-17 Central European Time)
- * UUCP: weicker@ztivax.uucp@unido.uucp
- * Internet: weicker@ztivax.siemens.com
- *
- * 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)
- *
- * Collection of Results:
- * Reinhold Weicker (address see above) and
- *
- * Rick Richardson
- * PC Research. Inc.
- * 94 Apple Orchard Drive
- * Tinton Falls, NJ 07724
- * Phone: (201) 834-1378 (9-17 EST)
- * UUCP: ...!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:
- * -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. The program is balanced with
- * respect to the three aspects:
- *
- * - statement type
- * - operand type
- * - operand locality
- * operand global, local, parameter, or constant.
- *
- * The combination of these three aspects is balanced only approximately.
- *
- * 1. Statement Type:
- * ----------------- number
- *
- * V1 = V2 9
- * (incl. V1 = F(..)
- * V = Constant 12
- * Assignment, 7
- * with array element
- * Assignment, 6
- * with record component
- * --
- * 34 34
- *
- * X = Y +|-|"&&"|"|" Z 5
- * X = Y +|-|"==" Constant 6
- * X = X +|- 1 3
- * X = Y *|/ Z 2
- * X = Expression, 1
- * two operators
- * X = Expression, 1
- * three operators
- * --
- * 18 18
- *
- * if .... 14
- * with "else" 7
- * without "else" 7
- * executed 3
- * not executed 4
- * for ... 7 | counted every time
- * while ... 4 | the loop condition
- * do ... while 1 | is evaluated
- * switch ... 1
- * break 1
- * declaration with 1
- * initialization
- * --
- * 34 34
- *
- * P (...) procedure call 11
- * user procedure 10
- * library procedure 1
- * X = F (...)
- * function call 6
- * user function 5
- * library function 1
- * --
- * 17 17
- * ---
- * 103
- *
- * The average number of parameters in procedure or function calls
- * is 1.82 (not counting the function values as implicit parameters).
- *
- *
- * 2. Operators
- * ------------
- * number approximate
- * percentage
- *
- * Arithmetic 32 50.8
- *
- * + 21 33.3
- * - 7 11.1
- * * 3 4.8
- * / (int div) 1 1.6
- *
- * Comparison 27 42.8
- *
- * == 9 14.3
- * /= 4 6.3
- * > 1 1.6
- * < 3 4.8
- * >= 1 1.6
- * <= 9 14.3
- *
- * Logic 4 6.3
- *
- * && (AND-THEN) 1 1.6
- * | (OR) 1 1.6
- * ! (NOT) 2 3.2
- *
- * -- -----
- * 63 100.1
- *
- *
- * 3. Operand Type (counted once per operand reference):
- * ---------------
- * number approximate
- * percentage
- *
- * Integer 175 72.3 %
- * Character 45 18.6 %
- * Pointer 12 5.0 %
- * String30 6 2.5 %
- * Array 2 0.8 %
- * Record 2 0.8 %
- * --- -------
- * 242 100.0 %
- *
- * When there is an access path leading to the final operand (e.g. a
- * record component), only the final data type on the access path is
- * counted.
- *
- *
- * 4. Operand Locality:
- * -------------------
- * number approximate
- * percentage
- *
- * local variable 114 47.1 %
- * global variable 22 9.1 %
- * parameter 45 18.6 %
- * value 23 9.5 %
- * reference 22 9.1 %
- * function result 6 2.5 %
- * constant 55 22.7 %
- * --- -------
- * 242 100.0 %
- *
- *
- * The program does not compute anything meaningful, but it is
- * syntactically and semantically correct. All variables have a value
- * assigned to them before they are used as a source operand.
- *
- * There has been no explicit effort to account for the effects of a
- * cache, or to balance the use of long or short displacements for code
- * or data.
