the app would ignore foo by itself and usually people are working on having their tailored x86 code in shape for amd64 (using some tricks as usual...) I feel afraid since we are spending lot of time assuming our users don't have a clue about what they bought or that they cannot document themselves as they should for picking the right cpu/tune for the CFLAGS... Diego's proposal could be nice for remove some options and prevent the burden of keeping a long list of useflag due the Intel vs Amd war on the extensions, sadly I think was pointed that isn't a complete solution and many would be unhappy about it. Having a USE_EXPAND for the cpu feats could a little improvement if we expect sse99 or 5dnowultra appear within the year since we could stuff all this cruft in a single place and have a separate use.desc for them. I hope I'm not too tired and I didn't miss something ^^ lu -- Luca Barbato Gentoo/linux Gentoo/PPC http://dev.gentoo.org/~lu_zero -- gentoo-dev@gentoo.org mailing list
