|
|
* Date: May 25, 1988
|
|
* Modified: Steven Pemberton, CWI, Amsterdam; Steven.Pemberton@cwi.nl
|
|
* Date: October, 1993; March 1995
|
|
* Included both files into one source, that gets compiled
|
|
* in two passes. Made program auto-compiling, and auto-running,
|
|
* and generally made it much easier to use.
|
|
*
|
|
* Original Version (in Ada) published in
|
|
* "Communications of the ACM" vol. 27., no. 10 (Oct. 1984),
|
|
* pp. 1013 - 1030, together with the statistics
|
|
* on which the distribution of statements etc. is based.
|
|
*
|
|
* In this C version, the following C library functions are used:
|
|
* - strcpy, strcmp (inside the measurement loop)
|
|
* - printf, scanf (outside the measurement loop)
|
|
* In addition, Berkeley UNIX system calls "times ()" or "time ()"
|
|
* are used for execution time measurement. For measurements
|
|
* on other systems, these calls have to be changed.

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

|
|
* Defines: The following "Defines" are possible:
|
|
* -DREG (default: Not defined)
|
|
* As an approximation to what an average C programmer
|
|
* might do, causes the "register" storage class to be applied
|
|
* - 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.
|
|
* -DTIMES (default)
|
|
* -DTIME
|
|
* The "times" function of UNIX (returning process times)
|
|
* or the "time" function (returning wallclock time)
|
|
* is used for measurement.
|
|
* For single user machines, "time ()" is adequate. For
|
|
* multi-user machines where you cannot get single-user
|
|
* access, use the "times ()" function. If you have
|
|
* neither, use a stopwatch in the dead of night.
|
|
* "printf"s are provided marking the points "Start Timer"
|
|
* and "Stop Timer". DO NOT use the UNIX "time(1)"
|
|
* command, as this will measure the total time to
|
|
* run this program, which will (erroneously) include
|
|
* the time to allocate storage (malloc) and to perform
|
|
* the initialization.
|
|
* -DHZ=nnn
|
|
* In Berkeley UNIX, the function "times" returns process
|
|
* time in 1/HZ seconds, with HZ = 60 for most systems.
|
|
* CHECK YOUR SYSTEM DESCRIPTION BEFORE YOU JUST APPLY
|
|
* A VALUE.

***************************************************************************
|
|
*
|
|
* History: Version C/2.1 was made for two reasons:
|
|
*
|
|
* 1) There was 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.
|
|
*
|
|
* Version C/2.2, Steven Pemberton, October 1993
|
|
* Functionally, identical to version 2.2; the changes are in
|
|
* how you compile and use it:
|
|
* - Everything is in one file now, but compiled in 2 passes
|
|
* - Compile (and run) by running the file through the shell: 'sh dhry.c"
|
|
* - Uses the system definition of HZ if one can be found
|
|
* - HZ must be defined, otherwise it won't compile (no defaults here)
|
|
* - The (uninteresting) output is printed to stderr (dhry2 > /dev/null)
|
|
* - The number of loops is passed as a parameter, rather than read
|
|
* (dhry2 500000)
|
|
* - If the number of loops is insufficient to get a good result,
|
|
* it repeats it with loops*10 until it is enough (rather than just
|
|
* stopping)
|
|
* - Output says which sort of clock it is using, and the HZ value
|
|
* - You can use -DREG instead of the -DREG=register of previous versions
|
|
* - Some stylistic cleanups.
|
|
*
|
|
***************************************************************************
|
|
*
|
|
* Compilation model and measurement (IMPORTANT):
|
|
*
|
|
* 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.
|
|

|
|

* 242 100.0 %
|

|
|
* local variable 114 47.1 %

* 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.
