   1 /** Sanatised version of the dhrystone-2.1 test.
   2
   3     Modifications Michael Hope <michaelh@earthling.net>
   4
   5     This is derrived from the dhrystone-2.1.tar.gz tarball available
   6     all over the net.  I sourced it from the Red Hat src rpm.
   7
   8     Modifications:
   9     * Made it more ANSI compliant.
  10     * Changed any array function arguments to pointers to make my
  11       compiler work.
  12     * Removed malloc's for a couple of static arrays.
  13     * Into one file.
  14     * Proc_8 is a bit messy.  It originally took a 2 dim array, but
  15       sdcc doesn't support this.  So the offsets are hard coded...
  16
  17     Notes:
  18     * The comment at the start of Func_1 about the input being
  19       H, R on the first call is wrong - Func_1 is first called
  20       from Func_2 where the input is R, Y.  The test still succeeds.

  29     A SPECIAL THANKS
  30     I didn't write the DHRYSTONE benchmark.  Rheinhold Weicker did. He has
  31     certainly provided us with a useful tool for benchmarking, and is
  32     to be congratulated.
