Hello Everyone,
I've just been playing with the -march flags and found a huge speed increase
when I used -march=pentuim. If this works so good, why is there a push for a
pentium optimized gcc? Doesn't -march=pentium make pentium optimized code?
It does seem to speed things up alot. I had tried PGCC and was a little
disappointed with the speed increases so I stayed with regular Djgpp. Now it
seems that I had a pentium optimizing compiler all along. I'm confused...
Does anyone know of any gotcha's with using -march=pentium flags?
Thanks,
Doug Eleveld
