*
|

* - strcpy, strcmp (inside the measurement loop)
|
||||
* - printf, scanf (outside the measurement loop)
|

* In addition, Berkeley UNIX system calls "times ()" or "time ()"
|

*
|

* 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.

|
||||
***************************************************************************
|
||||
*
|
||||
* 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:
|
||||
* -DREG=register (default: Not defined)
|
||||
* As an approximation to what an average C programmer
|
||||
* might do, the "register" storage class is applied
|
||||
* (if enabled by -DREG=register)
|
||||
* - 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.

|

*
|
||||
* 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.
|
||||
*
|
||||
* 1. Statement Type:
|
||||
* ----------------- number

|

* Arithmetic 32 50.8
|
||||
*
|

* Logic 4 6.3
|
||||

* && (AND-THEN) 1 1.6
|
||||
* | (OR) 1 1.6
|
||||
* ! (NOT) 2 3.2
|
||||
*
|
||||
* -- -----
|
||||
* 63 100.1
|
||||
*
|
||||
*
|
||||
* 3. Operand Type (counted once per operand reference):
|
||||
* ---------------
|
||||
* number approximate
|
||||
* percentage
|
||||
*
|
||||
* Integer 175 72.3 %
|
||||
* Character 45 18.6 %
|
||||
* Pointer 12 5.0 %
|
||||
* String30 6 2.5 %
|
||||
* Array 2 0.8 %
|
||||
* 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
|
||||
*
|
||||
* 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.
