Stupid question though ... does the gcc test thingy list __3dNOW__ on nocona ? I would think that it does, as there is no -march=3Dnocona (or whatever) yet. So now you want to instead of fixing the amd64 profiles to be more flexible, implement something that will give the green light to users on x86 to use flag combinations, especially on older gcc's that causes great pain for themselfs and developers ? Sure, nocona should have had CFLAGS=3D"-march=3Dk8 -mno-3dnow", but it woul= d never have been an issue if the '3dnow' USE flag worked as expected on amd64 ;) Anyhow, just ranting - I understand the reasoning for doing it that way, but you should also see it from the x86 side where -msse could really mean a broken system, and maybe rethink your solution. --=20 Martin Schlemmer --=-vog5lpm4Bgg3aTV2sipI Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (GNU/Linux) iD8DBQBErlS9qburzKaJYLYRAu9cAJ9V06fft9oAdLgUsQiu7kmF17j9bQCeK0EV MxTjVbvKgYfwMz+O5X2YX0U= =LS/A -----END PGP SIGNATURE----- --=-vog5lpm4Bgg3aTV2sipI-- -- gentoo-dev@gentoo.org mailing list
