// *      "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.
