Henrik Gramner	ab43beefab	x86inc: Drop SECTION_TEXT macro The .text section is already 16-byte aligned by default on all supported platforms so `SECTION_TEXT` isn't any different from `SECTION .text`. Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago
Henrik Gramner	9f1245eb96	x86inc: Support arbitrary stack alignments Change ALLOC_STACK to always align the stack before allocating stack space for consistency. Previously alignment would occur either before or after allocating stack space depending on whether manual alignment was required or not. Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago

James Almer	5750d6c5e9	x86: move XOP emulation code back to x86inc Only two functions that use xop multiply-accumulate instructions where the first operand is the same as the fourth actually took advantage of the macros. This further reduces differences with x264's x86inc. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>	10 years ago
Henrik Gramner	ebaf571aca	x86: dct: Disable dct32_float_sse on x86-64 There is an SSE2 implementation so the SSE version is never used. The "SSE" version also happens to contain SSE2 instructions on x86-64. Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago

Henrik Gramner	a344e5d094	x86: bswapdsp: Don't treat 32-bit integers as 64-bit The upper halves are not guaranteed to be zero in x86-64. Also use `test` instead of `and` when the result isn't used for anything other than as a branch condition, this allows some register moves to be eliminated.

Ronald S. Bultje	d32d0593f1	vp9: disable more pmulhrsw optimizations in idct16/32. For idct16, only when called from a adst16x16 variant, so impact is minor. For idct32, for all, so relatively major impact.	10 years ago
