Ok, but then please tell me another easy way how I can proofe the quality of the resulting code... I simply thought, that _if_ there are patches for gcc, that add support for a Pentium processor, then nearly every kind of executable should speed up because gcc now uses the whole power of ... hmmm let's say instruction set. I really didn't expect slower results. Please explain to me why you think, that those Pertium patches are possibly really ok if the dhrystone result is relatively poor.
