/** Sanatised version of the dhrystone-2.1 test. Modifications Michael Hope This is derrived from the dhrystone-2.1.tar.gz tarball available all over the net. I sourced it from the Red Hat src rpm. Modifications: * Made it more ANSI compliant. * Changed any array function arguments to pointers to make my compiler work. * Removed malloc's for a couple of static arrays. * Into one file. * Proc_8 is a bit messy. It originally took a 2 dim array, but sdcc doesn't support this. So the offsets are hard coded... Notes: * The comment at the start of Func_1 about the input being H, R on the first call is wrong - Func_1 is first called from Func_2 where the input is R, Y. The test still succeeds. References: * http://www.netlib.org/performance/html/dhry.intro.html * http://www.netlib.org/performance/html/dhry.data.col0.html I couldnt find a copyright in the original - the most relevent part follows: A SPECIAL THANKS I didn't write the DHRYSTONE benchmark. Rheinhold Weicker did. He has certainly provided us with a useful tool for benchmarking, and is to be congratulated. Rick Richardson PC Research, Inc.
