Christophe Gisquet	9107612818	x86util: add and use RSHIFT/LSHIFT macros Those macros take a byte number as shift argument, as this argument differs between MMX and SSE2 instructions. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Martin Storsjö	570d4b2186	x86: h264: Don't keep data in the redzone across function calls on 64 bit unix We know that the called function (ff_chroma_inter_body_mmxext) doesn't touch the redzone, and thus will be kept intact - thus, this doesn't fix any bug per se. However, valgrind's memcheck tool intentionally assumes that the redzone is clobbered on every function call and function return (see a long comment in valgrind/memcheck/mc_main.c). This avoids false positives in that tool, at the cost of an extra stack pointer adjustment. The other alternative would be a valgrind suppression for this issue, but that's an extra burden for everybody that wants to run libavcodec within valgrind.

James Almer	6d408495b5	x86/dct32: don't build ff_dct32_float_sse on x86_64 There's an SSE2 version already, and technically the SSE version on x86_64 was wrong (using pshufd and pshuflw, SSE2 instructions).

Christophe Gisquet	0810608e23	x86: hevc_mc: better register allocation The xmm reg count was incorrect, and manual loading of the gprs furthermore allows to noticeable reduce the number needed.
