 *************************************************************************

 *

 *  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.

 *     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

 *     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.
