Yes, this is what I usually hear about most compilers. P5 Code runs as fast or faster on 486's. What GCC needs is a to have the 486 generator perform pentium optimizations and not use pentium/386 instructions. Then we could compile everything for this. The speed hit on a pentium would drop on alot of apps and the 486/386 would not have any hit.. I wonder what instructions gcc uses on the 586, I don't recall seeing that many usefull ones for general purpose stuff..
