* Consistently use "cpu_flags" as variable/parameter name for CPU flagsDiego Biurrun2013-07-18
|
* cosmetics: Remove unnecessary extern keywords from function declarationsDiego Biurrun2013-03-27
|

|
* x86: lavr: add SSE2 quantize() for ditheringJustin Ruggles2013-01-08
|
* x86: lavr: use the x86inc.asm automatic stack alignment in mixing functionsJustin Ruggles2013-01-05
| | | | CC:libav-stable@libav.org
* x86: lavr: fix stack allocation for 7 and 8 channel downmixing on x86-32Ronald S. Bultje2012-11-17
| | | | Fixes crashes on Win32 and stack overruns on x86-32 in general.
* build: Drop AVX assembly ifdefsDiego Biurrun2012-11-11
| | | | An assembler able to cope with AVX instructions is now required.
* x86: PALIGNR: port to cpuflagsDiego Biurrun2012-11-09
|
* x86: avresample: Add missing colons to assembly labelsDiego Biurrun2012-11-06
| | | | YASM accepts labels without colons, but NASM issues warnings.
* x86: yasm: Use complete source path for macro helper %includesDiego Biurrun2012-10-31
| | | | | This is more consistent with the way we handle C #includes and it simplifies the build system.
* x86: include x86inc.asm in x86util.asmDiego Biurrun2012-10-31
| | | | This is necessary to allow refactoring some x86util macros with cpuflags.
* lavr: handle clipping in the float to s32 conversionJustin Ruggles2012-10-13
| | | | | | | | | | | We cannot clip to INT_MAX because that value cannot be exactly represented by a float value and ends up overflowing during conversion anyway. We need to use a slightly smaller float value, which ends up with slightly inaccurate results for samples which clip or nearly clip, but it is close enough. Using doubles as intermediates in the conversion would be more accurate, but it takes about twice as much time. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* x86: Replace checks for CPU extensions and flags by convenience macrosDiego Biurrun2012-09-08
| | | | | This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.
* x86: Split inline and external assembly #ifdefsDiego Biurrun2012-08-31
|
* x86: cosmetics: Comment some #endifs for better readabilityDiego Biurrun2012-08-30

* x86: add colons after labelsMans Rullgard2012-08-07
| | | | | | nasm prints a warning if the colon is missing. Signed-off-by: Mans Rullgard <mans@mansr.com>
* lavr: x86: improve non-SSE4 version of S16_TO_S32_SX macroJustin Ruggles2012-07-27
| | | | | Removes a false dependency on existing contents of the 2nd dst register, giving better performance for OOE.
* lavr: add x86-optimized mixing functionsJustin Ruggles2012-07-27
| | | | | Adds optimized functions for mixing 3 through 8 input channels to 1 and 2 output channels in fltp or s16p format with flt coeffs.
* x86inc: automatically insert vzeroupper for YMM functions.Ronald S. Bultje2012-07-26
|
* lavr: x86: add missing vzeroupper in ff_mix_1_to_2_fltp_flt()Justin Ruggles2012-07-25
|
* lavr: x86: fix ff_conv_fltp_to_flt_6ch function prototypesJustin Ruggles2012-06-26
| | | | | | Changed to match the number of parameters in conv_func_interleave(), which is how they are called. The change isn't strictly necessary because the 4th parameter is not used, but the code is clearer if they match.

* lavr: replace the SSE version of ff_conv_fltp_to_flt_6ch() with SSE4 and AVXJustin Ruggles2012-05-09
| | | | | The current SSE version is slower than the MMX version on Athlon64 and Sandy Bridge, but the SSE4 and AVX versions are faster on Sandy Bridge.
