* "DHRYSTONE" Benchmark Program
*
* Version: C/1.1, 12/01/84
*
* Date: PROGRAM updated 01/06/86, RESULTS updated 03/31/86
*
* Author: Reinhold P. Weicker, CACM Vol 27, No 10, 10/84 pg. 1013
* Translated from ADA by Rick Richardson
* Every method to preserve ADA-likeness has been used,
* at the expense of C-ness.
*
* Compile: cc -O dry.c -o drynr : No registers
* cc -O -DREG=register dry.c -o dryr : Registers
*
* Defines: Defines are provided for old C compiler's
* which don't have enums, and can't assign structures.
* The time(2) function is library dependant; Most
* return the time in seconds, but beware of some, like
* Aztec C, which return other units.
* The LOOPS define is initially set for 50000 loops.
* If you have a machine with large integers and is
* very fast, please change this number to 500000 to
* get better accuracy. Please select the way to
* measure the execution time using the TIME define.
* For single user machines, time(2) is adequate. For
* multi-user machines where you cannot get single-user
* access, use the times(2) function. If you have
* neither, use a stopwatch in the dead of night.
* Use a "printf" at the point marked "start timer"
* to begin your timings. 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 malloc(3) storage and to compute the
* time it takes to do nothing.
*
* Run: drynr; dryr
*
* Results: If you get any new machine/OS results, please send to:
*
* ihnp4!castor!pcrat!rick
*
* and thanks to all that do. Space prevents listing
* the names of those who have provided some of these
* results. I'll be forwarding these results to
* Rheinhold Weicker.
*
* Note: I order the list in increasing performance of the
* "with registers" benchmark. If the compiler doesn't
* provide register variables, then the benchmark
* is the same for both REG and NOREG.
*
* PLEASE: Send complete information about the machine type,
* clock speed, OS and C manufacturer/version. If
* the machine is modified, tell me what was done.
* On UNIX, execute uname -a and cc -V to get this info.
*
* 80x8x NOTE: 80x8x benchers: please try to do all memory models
* for a particular compiler.
*
* APOLOGY (1/30/86):
* Well, I goofed things up! As pointed out by Haakon Bugge,
* the line of code marked "GOOF" below was missing from the
* Dhrystone distribution for the last several months. It
* *WAS* in a backup copy I made last winter, so no doubt it
* was victimized by sleepy fingers operating vi!
*
* The effect of the line missing is that the reported benchmarks
* are 15% too fast (at least on a 80286). Now, this creates
* a dilema - do I throw out ALL the data so far collected
* and use only results from this (corrected) version, or
* do I just keep collecting data for the old version?
*
* Since the data collected so far *is* valid as long as it
* is compared with like data, I have decided to keep
* TWO lists- one for the old benchmark, and one for the
* new. This also gives me an opportunity to correct one
* other error I made in the instructions for this benchmark.
* My experience with C compilers has been mostly with
* UNIX 'pcc' derived compilers, where the 'optimizer' simply
* fixes sloppy code generation (peephole optimization).
* But today, there exist C compiler optimizers that will actually
* perform optimization in the Computer Science sense of the word,
* by removing, for example, assignments to a variable whose
* value is never used. Dhrystone, unfortunately, provides
* lots of opportunities for this sort of optimization.
*
* I request that benchmarkers re-run this new, corrected
* version of Dhrystone, turning off or bypassing optimizers
* which perform more than peephole optimization. Please
* indicate the version of Dhrystone used when reporting the
* results to me.

* G1 This Gould machine has 2 processors and was able to run 2 dhrystone
* Benchmarks in parallel with no slowdown.
* FH FHC == Frank Hogg Labs (Hazelwood Uniquad 2 in an FHL box).
* FX The Alliant FX/8 is a system consisting of 1-8 CEs (computation
* engines) and 1-12 IPs (interactive processors). Note N8 applies.
* RT This is one of the RT's that CMU has been using for awhile. I'm

* to the public.
* i1 Normally, the 386/20 starter kit has a 16k direct mapped cache
* which inserts 2 or 3 wait states on a write thru. These results
* were obtained by disabling the write-thru, or essentially turning
* the cache into 0 wait state memory.
* Nnn This machine has multiple processors, allowing "nn" copies of the
* benchmark to run in the same time as 1 copy.
* &nn This machine has "nn" processors, and the benchmark results were
* obtained by having all "nn" processors working on 1 copy of dhrystone.
* (Note, this is different than Nnn. Salesmen like this measure).
* ? I don't trust results marked with '?'. These were sent to me with
* either incomplete info, or with times that just don't make sense.
* ?? means I think the performance is too poor, ?! means too good.

*--------------------------------RESULTS END----------------------------------
*
* The following program contains statements of a high-level programming
* language (C) in a distribution considered representative:
*
* assignments 53%
* control statements 32%
* procedure, function calls 15%
*
* 100 statements are dynamically executed. The program is balanced with
* respect to the three aspects:
* - statement type
* - operand type (for simple data types)
* - operand access
* operand global, local, parameter, or constant.
*
* The combination of these three aspects is balanced only approximately.
*
* The program does not compute anything meaningfull, but it is
* syntactically and semantically correct.
