* x86inc: Set ELF hidden visibility for global constantsHenrik Gramner2013-10-07
| | | | Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* x86inc: activate REP_RET automaticallyLoren Merritt2013-10-07
| | | | | | | | | | | | 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.

| | | | | | Because of -Werror=implicit-function-declaration the build will fail. Signed-off-by: Martin Storsjö <martin@martin.st>

|
* x86: float dsp: butterflies_float SSEChristophe Gisquet2013-05-03
| | | | | 97c -> 49c Some codecs could benefit from more unrolling, but AAC doesn't.
* dsputil: Make dsputil selectableRonald S. Bultje2013-04-10
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* x86inc: Fix number of operands for cmp* instructionsChristophe Gisquet2013-04-09
| | | | | | cmp{p,s}{s,d} instructions do take an imm8 operand. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* cosmetics: Remove unnecessary extern keywords from function declarationsDiego Biurrun2013-03-27
|
* x86: Use simple nop codes for <= sse (rather than <= mmx)Ronald S. Bultje2013-02-19
| | | | | | | | The "CentaurHauls family 6 model 9 stepping 8" family of CPUs (flags: fpu vme de pse tsc msr cx8 sep mtrr pge mov pat mmx fxsr sse up rng rng_en ace ace_en) SIGILLs on long nop codes. Signed-off-by: Martin Storsjö <martin@martin.st>
* avutil: Ensure that emms_c is always defined, even on non-x86Diego Biurrun2013-02-14
|
* avutil: Move emms code to x86-specific headerDiego Biurrun2013-02-14
|
* floatdsp: move scalarproduct_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | This makes the aac decoder and all voice codecs independent of dsputil.
* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | | 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.
* floatdsp: move vector_fmul_add from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
|
* x86: Add a Yasm-based emms() replacementMartin Storsjö2013-01-18
| | | | | | | This provides a fallback when building with Yasm enabled, but neither inline assembly, nor the _mm_empty intrinsic are available or enabled. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* x86inc: Add cvisible macro for C functions with public prefixDiego Biurrun2013-01-18
| | | | | | This allows defining externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* x86inc: Rename "program_name" to "private_prefix"Diego Biurrun2013-01-18
| | | | | | | The new name is more descriptive and will allow defining a separate public prefix for externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* float_dsp: Add #ifdef HAVE_INLINE_ASM around vector_fmul_windowMartin Storsjö2013-01-17
| | | | | | This fixes builds on 64bit MSVC. Signed-off-by: Martin Storsjö <martin@martin.st>

* x86inc: support stack mem allocation and re-alignment in PROLOGUERonald S. Bultje2012-12-12
| | | | | | | Use this in VP8/H264-8bit loopfilter functions so they can be used if there is no aligned stack (e.g. MSVC 32bit or ICC 10.x). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* x86: float_dsp: fix loading of the len parameter on x86-32Justin Ruggles2012-12-07

* x86inc: Set program_name outside of x86inc.asmDiego Biurrun2012-11-11
| | | | This reduces the local difference to the x264 upstream version.
