* x86: float dsp: unroll SSE versionsChristophe Gisquet2014-02-201-16/+24
| | | | | | | | | | 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 <[email protected]>
* x86inc: Speed up assembling with YasmLoren Merritt2014-01-261-23/+23
| | | | | | | Work around Yasm's inefficiency with handling large numbers of variables in the global scope. Signed-off-by: Diego Biurrun <[email protected]>
* libavutil: x86: Add AVX2 capable CPU detection.Kieran Kunhya2013-10-252-0/+11
| | | | | | Patch based on x264's AVX2 detection Signed-off-by: Derek Buitenhuis <[email protected]>
* x86: more AVX2 frameworkJason Garrett-Glaser2013-10-141-0/+11

* x86inc: FMA3/4 SupportJason Garrett-Glaser2013-10-142-1/+45

* x86inc: Remove our FMA4 supportDerek Buitenhuis2013-10-142-11/+16
| | | | | | | | This is so we can sync to x264's version of FMA4 support. This partialy reverts commit 79687079a97a039c325ab79d7a95920d800b791f. Signed-off-by: Derek Buitenhuis <[email protected]>
* x86inc: Use VEX-encoded instructions in AVX functionsHenrik Gramner2013-10-141-84/+169
| | | | | | | | | | | | | 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 <[email protected]>
* x86inc: Remove .rodata kludgesHenrik Gramner2013-10-091-11/+5
| | | | | | | 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 <[email protected]>
* x86inc: remove misaligned cpu flagHenrik Gramner2013-10-071-5/+4
| | | | | | | | | | | | 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 <[email protected]>
* x86inc: various minor backports from x264Jason Garrett-Glaser2013-10-071-4/+3
| | | | | | Small backports that sneaked into other asm commits in x264. Signed-off-by: Derek Buitenhuis <[email protected]>
* x86inc: Check for __OUTPUT_FORMAT__ having a value of "x64"Derek Buitenhuis2013-10-071-0/+2
| | | | | | This is also a valid value for WIN64. Signed-off-by: Derek Buitenhuis <[email protected]>
* x86inc: Utilize the shadow space on 64-bit WindowsHenrik Gramner2013-10-071-37/+46
| | | | | | | | | 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 <[email protected]>
* x86inc: create xm# and ym#, analagous to m#Loren Merritt2013-10-071-1/+25
| | | | | | For when we want to mix simd sizes within one function. Signed-off-by: Derek Buitenhuis <[email protected]>
* x86inc: fix some corner cases of SWAPLoren Merritt2013-10-071-27/+27
| | | | | | | | 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 <[email protected]>
* x86inc: Use SSE instead of SSE2 for copying dataHenrik Gramner2013-10-071-2/+2
| | | | | | | Reduces code size because movaps/movups is one byte shorter than movdqa/movdqu. Signed-off-by: Derek Buitenhuis <[email protected]>
* x86inc: Set ELF hidden visibility for global constantsHenrik Gramner2013-10-071-1/+5
| | | | Signed-off-by: Derek Buitenhuis <[email protected]>
* x86inc: activate REP_RET automaticallyLoren Merritt2013-10-071-5/+31
| | | | | | | | | | | | 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 <[email protected]>
* avutil: Fix compilation with inline asm disabled on mingwAlex Smith2013-09-221-0/+1

|
* floatdsp: move scalarproduct_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-222-0/+28
| | | | This makes the aac decoder and all voice codecs independent of dsputil.
* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-222-0/+44
| | | | | | 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.

|
* x86: Add a Yasm-based emms() replacementMartin Storsjö2013-01-183-0/+55
