1 /** Sanatised version of the dhrystone-2.1 test.
3 Modifications Michael Hope <michaelh@earthling.net>
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.
9 * Made it more ANSI compliant.
10 * Changed any array function arguments to pointers to make my
12 * Removed malloc's for a couple of static arrays.
14 * Proc_8 is a bit messy. It originally took a 2 dim array, but
15 sdcc doesnt support this. So the offsets are hard coded...
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.
