Details

There is 2 issues. - media/libvpx/moz.build doesn't build AVX2 intrinsic source code. Now, it is OSX only. - Re-generate vp9_rtcd_x86-darwin9-gcc.h to enable avx2. This files never calls AVX2 intrinsic. Also, we need check on configure whether current compiler supports AVX2 intrinsic.

Jean-Yves, do we care about enabling AVX2 for libvpx on Linux? Or can we WONTFIX this bug from 2014?

For media it doesn't matter anymore, as we will no longer be using libvpx to decode. However, WebRTC still uses it, and I would assume AVX2 provide a goot speed improvement (and I haven't verified that of course)

Maire - this still needs to be fixed for WebRTC. Do you have someone who can spend time on it?

Ralph -- Is AVX2 now enabled on all platforms? Can we close this bug? (ref: Bug 1225217) Thanks!
Flags: needinfo?(mreavy) → needinfo?(giles)
As far as I can tell, AVX2 is enabled for linux now. Thanks for the report!
