* "DHRYSTONE" Benchmark Program
*
* Version: C/1
* Date: 12/01/84, RESULTS updated 10/22/85
* 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; One is
* provided for CI-C86. Your compiler may be different.
* 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,vax135,..}!houxm!vaximile!rer
* and thanks to all that do. Space prevents listing
* the names of those who have provided some of these
* results.
* 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. I'm not going
* to list a compiler in a better place because if it
* had register variables it might do better. No
* register variables is a big loss in my book.
* 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.
* Otherwise, I won't include it in this list. My
* favorite flame on this subject was a machine that
* was listed as an IBM PC/XT 8086-9.54Mhz. That must
* have been some kind of co-processor board that ran
* the benchmark, not the XT. Tell me what it was!

* 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.
