[Jason Garrett-Glaser]

x264 | branch: master | Jason Garrett-Glaser <jason at x264.com> | Wed Jan 12 09:54:33 2011 -0800| [f74136eaf9ab150a147684ac3189fbafd82f044f] | committer: Jason Garrett-Glaser

Initial AVX support
Automatically handle 3-operand instructions and abstraction between SSE and AVX.
Implement one function with this (denoise_dct) as an initial test.
x264 can't make much use of the 256-bit support of AVX (as it's float-only), but 3-operand could give some small benefits.
