X * Original Version (in Ada) published in
X * "Communications of the ACM" vol. 27., no. 10 (Oct. 1984),
X * pp. 1013 - 1030, together with the statistics
X * on which the distribution of statements etc. is based.
X *
X * In this C version, the following C library functions are used:
X * - strcpy, strcmp (inside the measurement loop)
X * - printf, scanf (outside the measurement loop)
X * In addition, UNIX system calls "times ()" or "time ()"
X * are used for execution time measurement. For measurements
X * on other systems, these calls have to be changed.

X * The Operating System version may give an indication about the

X ***************************************************************************
X *
X * History: This version C/2.0 has been made for two reasons:
X *
X * 1) There is an obvious need for a common C version of
X * Dhrystone, since C is at present the most popular system
X * programming language for the class of processors
X * (microcomputers, minicomputers) where Dhrystone is used most.
X * There should be, as far as possible, only one C version of
X * Dhrystone such that results can be compared without
X * restrictions. In the past, the C versions distributed
X * by Rick Richardson (Version 1.1) and by Reinhold Weicker
X * had small (though not significant) differences.
X *
X * 2) As far as it is possible without changes to the Dhrystone
X * statistics, optimizing compilers should be prevented from
X * removing significant statements.
X *
X * This C version has been developed in cooperation with
X * Rick Richardson (Tinton Falls, NJ), it incorporates many
X * ideas from the "Version 1.1" distributed previously by
X * him over the UNIX network Usenet.
X * I also thank Chaim Benedelac (National Semiconductor),
X * David Ditzel (SUN), Earl Killian and John Mashey (MIPS),
X * Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley)
X * for their help with comments on earlier versions of the
X * benchmark.
X *
X * Changes: In the initialization part, this version follows mostly
X * Rick Richardson's version distributed via Usenet, not the
X * version distributed earlier via floppy disk by Reinhold Weicker.
X * As a concession to older compilers, names have been made
X * unique within the first 8 characters.
X * Inside the measurement loop, this version follows the
X * version previously distributed by Reinhold Weicker.
X *
X * At several places in the benchmark, code has been added,
X * but within the measurement loop only in branches that
X * are not executed. The intention is that optimizing compilers
X * should be prevented from moving code out of the measurement
X * loop, or from removing code altogether. Since the statements
X * that are executed within the measurement loop have NOT been
X * changed, the numbers defining the "Dhrystone distribution"
X * (distribution of statements, operand types and locality)
X * still hold. Except for sophisticated optimizing compilers,
X * execution times for this version should be the same as
X * for previous versions.
X *
X * Since it has proven difficult to subtract the time for the
X * measurement loop overhead in a correct way, the loop check
X * has been made a part of the benchmark. This does have
X * an impact - though a very minor one - on the distribution
X * statistics which have been updated for this version.
X *
X * All changes within the measurement loop are described
X * and discussed in the companion paper "Rationale for
X * Dhrystone version 2".
X *
X * Because of the self-imposed limitation that the order and
X * distribution of the executed statements should not be
X * changed, there are still cases where optimizing compilers
X * may not generate code for some statements. To a certain
X * degree, this is unavoidable for small synthetic benchmarks.
X * Users of the benchmark are advised to check code listings
X * whether code is generated for all statements of Dhrystone.
X *
X ***************************************************************************
X *
X * Defines: The following "Defines" are possible:
X * -DREG=register (default: Not defined)
X * As an approximation to what an average C programmer
X * might do, the "register" storage class is applied
X * (if enabled by -DREG=register)
X * - for local variables, if they are used (dynamically)
X * five or more times
X * - for parameters if they are used (dynamically)
X * six or more times
X * Note that an optimal "register" strategy is
X * compiler-dependent, and that "register" declarations
X * do not necessarily lead to faster execution.
X * -DNOSTRUCTASSIGN (default: Not defined)
X * Define if the C compiler does not support
X * assignment of structures.
X * -DNOENUMS (default: Not defined)
X * Define if the C compiler does not support
X * enumeration types.
X * -DTIMES (default)
X * -DTIME
X * The "times" function of UNIX (returning process times)
X * or the "time" function (returning wallclock time)
X * is used for measurement.
X * For single user machines, "time ()" is adequate. For
X * multi-user machines where you cannot get single-user
X * access, use the "times ()" function. If you have
X * neither, use a stopwatch in the dead of night.
X * "printf"s are provided marking the points "Start Timer"
X * and "Stop Timer". DO NOT use the UNIX "time(1)"
X * command, as this will measure the total time to
X * run this program, which will (erroneously) include
X * the time to allocate storage (malloc) and to perform
X * the initialization.
X * -DHZ=nnn (default: 60)
X * The function "times" returns process times in
X * 1/HZ seconds, with HZ = 60 for most systems.
X * CHECK YOUR SYSTEM DESCRIPTION BEFORE YOU JUST APPLY
X * THE DEFAULT VALUE.
X *
X ***************************************************************************
X *
X * Compilation model and measurement (IMPORTANT):
X *
X * This C version of Dhrystone consists of three files:
X * - dhry_global.h (this file, containing global definitions and comments)
X * - dhry_pack_1.c (containing the code corresponding to Ada package Pack_1)
X * - dhry_pack_2.c (containing the code corresponding to Ada package Pack_2)
X *
X * The following "ground rules" apply for measurements:
X * - Separate compilation
X * - No procedure merging
X * - Otherwise, compiler optimizations are allowed but should be indicated
X * - Default results are those without register declarations
X * See the companion paper "Rationale for Dhrystone Version 2" for a more
X * detailed discussion of these ground rules.
X *
X * For 16-Bit processors (e.g. 80186, 80286), times for all compilation
X * models ("small", "medium", "large" etc.) should be given if possible,
X * together with a definition of these models for the compiler system used.
X *

X *
X * Dhrystone (C version) statistics:
X *
X * [Comment from the first distribution, updated for version 2.
X * Note that because of language differences, the numbers are slightly
X * different from the Ada version.]
X *
X * The following program contains statements of a high level programming
X * language (here: C) in a distribution considered representative:
X *
X * assignments 52 (51.0 %)
X * control statements 33 (32.4 %)
X * procedure, function calls 17 (16.7 %)
X *
X * 103 statements are dynamically executed. The program is balanced with
X * respect to the three aspects:
X *
X * - statement type
X * - operand type
X * - operand locality
X * operand global, local, parameter, or constant.
X *
X * The combination of these three aspects is balanced only approximately.
X *
X * 1. Statement Type:
X * ----------------- number
X *
X * V1 = V2 9
X * (incl. V1 = F(..)
X * V = Constant 12
X * Assignment, 7
X * with array element
X * Assignment, 6
X * with record component
X * --
X * 34 34
X *
X * X = Y +|-|"&&"|"|" Z 5
X * X = Y +|-|"==" Constant 6
X * X = X +|- 1 3
X * X = Y *|/ Z 2
X * X = Expression, 1
X * two operators
X * X = Expression, 1
X * three operators
X * --
X * 18 18
X *
X * if .... 14
X * with "else" 7
X * without "else" 7
X * executed 3
X * not executed 4
X * for ... 7 | counted every time
X * while ... 4 | the loop condition
X * do ... while 1 | is evaluated
X * switch ... 1
X * break 1
X * declaration with 1
X * initialization
X * --
X * 34 34
X *
X * P (...) procedure call 11
X * user procedure 10
X * library procedure 1
X * X = F (...)
X * function call 6
X * user function 5
X * library function 1
X * --
X * 17 17
X * ---
X * 103
X *
X * The average number of parameters in procedure or function calls
X * is 1.82 (not counting the function values as implicit parameters).
X *
X *
X * 2. Operators
X * ------------
X * number approximate
X * percentage
X *
X * Arithmetic 32 50.8
X *
X * + 21 33.3
X * - 7 11.1
X * * 3 4.8
X * / (int div) 1 1.6
X *
X * Comparison 27 42.8
X *
X * == 9 14.3
X * /= 4 6.3
X * > 1 1.6
X * < 3 4.8
X * >= 1 1.6
X * <= 9 14.3
X *
X * Logic 4 6.3
X *
X * && (AND-THEN) 1 1.6
X * | (OR) 1 1.6
X * ! (NOT) 2 3.2
X *
X * -- -----
X * 63 100.1
X *
X *
X * 3. Operand Type (counted once per operand reference):
X * ---------------
X * number approximate
X * percentage
X *
X * Integer 175 72.3 %
X * Character 45 18.6 %
X * Pointer 12 5.0 %
X * String30 6 2.5 %
X * Array 2 0.8 %
X * Record 2 0.8 %
X * --- -------
X * 242 100.0 %
X *
X * When there is an access path leading to the final operand (e.g. a record
X * component), only the final data type on the access path is counted.
X *
X *
X * 4. Operand Locality:
X * -------------------
X * number approximate
X * percentage
X *
X * local variable 114 47.1 %
X * global variable 22 9.1 %
X * parameter 45 18.6 %
X * value 23 9.5 %
X * reference 22 9.1 %
X * function result 6 2.5 %
X * constant 55 22.7 %
X * --- -------
X * 242 100.0 %
X *
X *
X * The program does not compute anything meaningful, but it is syntactically
X * and semantically correct. All variables have a value assigned to them
X * before they are used as a source operand.
X *
X * There has been no explicit effort to account for the effects of a
X * cache, or to balance the use of long or short displacements for code or
X * data.
