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, Berkeley 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 ***************************************************************************
X *
X *  History:    This version C/2.1 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 *              Version 2.1 is identical to version 2.0 distributed via
X *              the UNIX network Usenet in March 1988 except that it corrects
X *              some minor deficiencies that were found by users of version 2.0.
X *              The only change within the measurement loop is that a
X *              non-executed "else" part was added to the "if" statement in
X *              Func_3, and a non-executed "else" part removed from Proc_3.

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
X *                      In Berkeley UNIX, the function "times" returns process
X *                      time in 1/HZ seconds, with HZ = 60 for most systems.
X *                      CHECK YOUR SYSTEM DESCRIPTION BEFORE YOU JUST APPLY
X *                      A VALUE.

X *  Compilation model and measurement (IMPORTANT):
X *
X *  This C version of Dhrystone consists of three files:
X *  - dhry.h (this file, containing global definitions and comments)
X *  - dhry_1.c (containing the code corresponding to Ada package Pack_1)
X *  - dhry_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 *  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 *  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.
