I have -march=amdfam10 (Phenom) and I once watched the compilation of ffmpeg and it said something like "CPU family amdfam10 unknown" and it changed some of the CFLAGS (I can't remember which exactly) so I guess something like this is already somewhere under the hood. But I agree that a USE-Flag to decide over this behaviour would be great. -- Currently developing a browsergame... http://www.p-game.de Trade - Expand - Fight Follow me at twitter! http://twitter.com/moortier
