I can't figure out how the ebuild author could have come up with the set of CPU flags they did without noticing that they missed more than half of them...

Also missing are some arm architecture flags, neon, and vfp.

afaik the build system is ripped of libav/ffmpeg's one
have you checked that libpostproc actually has such optimizations?

Ah, that makes more sense. Looking at the code mmxext:mmx2 is missing and there is no VIS or 3dnowext:amd3dnowext support.
Comment 3 Matt Turner gentoo-dev 2013-02-10 21:51:28 UTC 
Done.
