Martin Storsjö	2e55e26b40	vp9: Flip the order of arguments in MC functions This makes it match the pattern already used for VP8 MC functions. This also makes the signature match ffmpeg's version of these functions, easing porting of code in both directions. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Ronald S. Bultje	9790b44a89	vp9mc/x86: sse2 MC assembly. Also a slight change to the ssse3 code, which prevents a theoretical overflow in the sharp filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
James Almer	67922b4ee4	vp9mc/x86: add AVX and AVX2 MC Roughly 25% faster MC than ssse3 for blocksizes 32 and 64. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago

James Almer	8be8444d01	vp9mc/x86: rename ff_avg[48]_sse to ff_avg[48]_mmxext pavgb is an sse integer instruction, so the mmxext flag is enough Signed-off-by: James Almer <jamrial@gmail.com> Reviewed-by: "Ronald S.

Ronald S. Bultje	8729964b99	vp9: split x86 assembly in two files. (And in future, loopfilter or intra pred could be put in their own respective files also.)	11 years ago
