- * Following source of a dhrystone benchmark was compiled for IBM OS/2 V1.1
- * (family application). Please note, that the benchmark differs in its
- * results depending on the compiler optimizations! (IBM PS2/70, 80386-25Mhz,
- * benchmarks at approx. 10.000 dhrystones under DOS and OS/2 using Microsofts
- * Compiler V.5.1, but 17.000 dhrystones under IBM's AIX using the
- * AIX-compiler!!!)
- *
- * There exists another dhrystone benchmark version, which I will get in some
- * days that supposedly is programmed in a way that should inhibit "too good"
- * of an optimization. If interested I shall submit it to the OS/2 list.

- * "DHRYSTONE" Benchmark Program
- *
- * Version: C/1
- * Date: 12/01/84, RESULTS updated 10/15/85
- * 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.
- * Run: drynr; dryr
- * 50000 Runs are made and the time is printed
- * Results: If you get any new machine/OS results, please send to:
- * ..!houxm!vaximile!rer
- * and thanks to all that do. Space prevents listing
- * the names of those who have provided some of these
- * results.

- * 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.
