The problem is that optimising for your system sounds all l33t and cool but really, it's not, it's a huge waste of time. The only meaty difference between i586 and the later processors so far as GCC cares are the additional instruction sets, MMX, SSE and 3D Now! These are particularly useful only to a tiny minority of applications. For the vast majority of applications you'll see no real increase in speed at all between compiling for i586 and compiling for athlon-xp. Don't start crying "gentoo!", because if you get speed boosts via gentoo it's generally by using very aggressive compilation options, not by targetting your own processor architecture. For the minority of applications for which compiling for MMX, in particular, is useful - basically, media encoders - there will be a system of alternative libraries, as Austin explained. -- adamw
