As far as I can tell, tuning for Sempron doesn't make much sense since this is not one specific design, but at least two different ones (the Socket A variant and the Socket 754 variant). > Why is GCC-4.2.x missing -march=k8 -mtune=athlonxp -mtune=athlon-xp > -mtune=athlon_xp -msse3 -m3dnow+ -m32? I don't think we should have variants for all sorts of spellings such as athlonxp vs athlon-xp vs athlon_xp. And if you check our fine manual, you will see that we actually support such options.
