- * "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.
