Loren Merritt	3fb78e99a0	x86inc: create xm# and ym#, analagous to m# For when we want to mix simd sizes within one function. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Loren Merritt	49ebe3f9fe	x86inc: fix some corner cases of SWAP SWAP with >=3 named (rather than numbered) args PERMUTE followed by SWAP with 2 named args used to produce the wrong permutation Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Henrik Gramner	63f0d62310	x86inc: Use SSE instead of SSE2 for copying data Reduces code size because movaps/movups is one byte shorter than movdqa/movdqu. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Henrik Gramner	ad76e6e7e1	x86inc: Set ELF hidden visibility for global constants Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Loren Merritt	25cb0c1a1e	x86inc: activate REP_RET automatically Now RET checks whether it immediately follows a branch, so the programmer dosen't have to keep track of that condition. REP_RET is still needed manually when it's a branch target, but that's much rarer. The implementation involves lots of spurious labels, but that's OK because we strip them.

Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.	12 years ago
