Christophe Gisquet	996697e266	x86: float dsp: unroll SSE versions vector_fmul and vector_fmac_scalar are guaranteed that they can process in batch of 16 elements, but their SSE versions only does 8 at a time. Therefore, unroll them a bit. 299 to 261c for 256 elements in vector_fmac_scalar on Arrandale/Win64. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Loren Merritt	b7d0d10a1d	x86inc: Speed up assembling with Yasm Work around Yasm's inefficiency with handling large numbers of variables in the global scope. Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Kieran Kunhya	4d6ee07255	libavutil: x86: Add AVX2 capable CPU detection. Patch based on x264's AVX2 detection Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Jason Garrett-Glaser	a3fabc6cb3	x86: more AVX2 framework Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Jason Garrett-Glaser	c6908d6b4b	x86inc: FMA3/4 Support Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Derek Buitenhuis	206895708e	x86inc: Remove our FMA4 support This is so we can sync to x264's version of FMA4 support. This partialy reverts commit `79687079a9`. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Henrik Gramner	c108ba0175	x86inc: Use VEX-encoded instructions in AVX functions Automatically use VEX-encoding in AVX/AVX2/XOP/FMA3/FMA4 functions for all instructions that exists in a VEX-encoded version. This change makes it easier to extend existing code to use AVX2. Also add support for AVX emulation of a few instructions that were missing before. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Henrik Gramner	ad7d7d4f6a	x86inc: Remove .rodata kludges The Mach-O bug was fixed in yasm 0.8.0 and we don't support versions that old anymore. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Henrik Gramner	3e2fa991db	x86inc: remove misaligned cpu flag Prevents a crash if the misaligned exception mask bit is cleared for some reason. Misaligned SSE functions are only used on AMD Phenom CPUs and the benefit is miniscule. They also require modifying the MXCSR control register and by removing those functions we can get rid of that complexity altogether. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Jason Garrett-Glaser	7115566541	x86inc: various minor backports from x264 Small backports that sneaked into other asm commits in x264. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Derek Buitenhuis	47f9d7ce54	x86inc: Check for __OUTPUT_FORMAT__ having a value of "x64" This is also a valid value for WIN64. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Henrik Gramner	bbe4a6db44	x86inc: Utilize the shadow space on 64-bit Windows Store XMM6 and XMM7 in the shadow space in functions that clobbers them. This way we don't have to adjust the stack pointer as often, reducing the number of instructions as well as code size. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
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>	11 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>	11 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>	11 years ago
Henrik Gramner	ad76e6e7e1	x86inc: Set ELF hidden visibility for global constants Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 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. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago

Ronald S. Bultje	d56668bd80	floatdsp: move scalarproduct_float from dsputil to avfloatdsp. This makes the aac decoder and all voice codecs independent of dsputil.	12 years ago
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
