* Original Version (in Ada) published in
25
* "Communications of the ACM" vol. 27., no. 10 (Oct. 1984),
26
* pp. 1013 - 1030, together with the statistics
27
* on which the distribution of statements etc. is based.
28
*
29
* In this C version, the following C library functions are used:
30
* - strcpy, strcmp (inside the measurement loop)
31
* - printf, scanf (outside the measurement loop)
32
* In addition, Berkeley UNIX system calls "times ()" or "time ()"
33
* are used for execution time measurement. For measurements
34
* on other systems, these calls have to be changed.

45
*
46
* Please send results to Rick Richardson and/or Reinhold Weicker.
47
* Complete information should be given on hardware and software used.
48
* Hardware information includes: Machine type, CPU, type and size
49
* of caches; for microprocessors: clock frequency, memory speed
50
* (number of wait states).
51
* Software information includes: Compiler (and runtime library)
52
* manufacturer and version, compilation switches, OS version.
53
* The Operating System version may give an indication about the
54
* compiler; Dhrystone itself performs no OS calls in the measurement
55
* loop.
56
*
57
* The complete output generated by the program should be mailed
58
* such that at least some checks for correctness can be made.

**************************************************************************
61
*
62
* This version has changes made by Roy Longbottom to conform to a common
63
* format for a series of standard benchmarks for PCs:
64
*
65
* Running time greater than 5 seconds due to inaccuracy of the PC clock.
66
*
67
* Automatic adjustment of run time, no manually inserted parameters.
68
*
69
* Initial display of calibration times to confirm linearity.
70
*
71
* Display of results within one screen (or at a slow speed as the test
72
* progresses) so that it can be seen to have run successfully.
73
*
74
* Facilities to type in details of system used etc.
75
*
76
* All results and details appended to a results file.

* For details of history, changes, other defines, benchmark construction
85
* statistics see official versions from ftp.nosc.mil/pub/aburto where

*
91
* Defines: The following "Defines" are possible:
92
* -DREG=register (default: Not defined)
93
* As an approximation to what an average C programmer
94
* might do, the "register" storage class is applied
95
* (if enabled by -DREG=register)
96
* - for local variables, if they are used (dynamically)
97
* five or more times
98
* - for parameters if they are used (dynamically)
99
* six or more times
100
* Note that an optimal "register" strategy is
101
* compiler-dependent, and that "register" declarations
102
* do not necessarily lead to faster execution.
103
* -DNOSTRUCTASSIGN (default: Not defined)
104
* Define if the C compiler does not support
105
* assignment of structures.
106
* -DNOENUMS (default: Not defined)
107
* Define if the C compiler does not support
108
* enumeration types.

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

*
111
* Compilation model and measurement (IMPORTANT):
112
*
113
* This C version of Dhrystone consists of three files:
114
* - dhry.h (this file, containing global definitions and comments)
115
* - dhry_1.c (containing the code corresponding to Ada package Pack_1)
116
* - dhry_2.c (containing the code corresponding to Ada package Pack_2)
117
*
118
* The following "ground rules" apply for measurements:
119
* - Separate compilation
120
* - No procedure merging
121
* - Otherwise, compiler optimizations are allowed but should be indicated
122
* - Default results are those without register declarations
123
* See the companion paper "Rationale for Dhrystone Version 2" for a more
124
* detailed discussion of these ground rules.
125
*
126
* For 16-Bit processors (e.g. 80186, 80286), times for all compilation
127
* models ("small", "medium", "large" etc.) should be given if possible,
128
* together with a definition of these models for the compiler system used.
