+ *
+ *************************************************************************
+ *
+ *  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.

+ *                           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.
