Janne Grunau	8563f98871	x86: use emms after ff_int32_to_float_fmul_scalar_sse Intel's Instruction Set Reference (as of September 2015) clearly states that cvtpi2ps switches to MMX state. Actual CPUs do not switch if the source is a memory location. The Instruction Set Reference from 1999 (Order Number 243191) describes this behaviour but all later versions I've seen have make no distinction whether MMX registers or memory is used as source. The documentation for the matching SSE2 instruction to convert to double (cvtpi2pd) was fixed (see the valgrind bug https://bugs.kde.org/show_bug.cgi?id=210264). It will take time to get a clarification and fixes in place. In the meantime it makes sense to change ff_int32_to_float_fmul_scalar_sse to be correct according to the documentation. The vast majority of users will have SSE2 so a change to the SSE version has little effect. Fixes fate-checkasm on x86 valgrind targets.

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

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.
