Diego Biurrun	b0be1ae792	x86: avcodec: Add a bunch of missing #includes for av_cold	11 years ago
Diego Biurrun	4958f35a2e	dsputil: Move apply_window_int16 to ac3dsp The (optimized) functions are used nowhere else.	11 years ago
Diego Biurrun	3ac7fa81b2	Consistently use "cpu_flags" as variable/parameter name for CPU flags	12 years ago
Diego Biurrun	1399931d07	x86: dsputil: Rename dsputil_mmx.h --> dsputil_x86.h The header is not (anymore) MMX-specific.	12 years ago
Diego Biurrun	7c00e9d8ae	x86: ac3dsp: Remove 3dnow version of ff_ac3_extract_exponents The function requires increasing the fuzz factor for the ac3/eac3 encode tests and even so makes fate fail. It only provides a slight encoding speedup for legacy CPUs that do not support SS2. Thus its benefit is not worth the trouble it creates and fixing it would be a waste of time.	12 years ago
Diego Biurrun	b6649ab503	cosmetics: Remove unnecessary extern keywords from function declarations	12 years ago
Michael Niedermayer	3e15775333	x86/ac3dsp_init: try to workaround ICC failure. The asm code is not valid for older compilers as it uses too many operands, ICC on x86_32 seems affected by this. This patch disables the affected code for ICC on x86_32 and should make it compileable again. A better fix would be to use fewer operands or to change this code to yasm, later is being worked on AFAIK so this is a temporary solution.

Mans Rullgard	30b3916425	ac3dec: make downmix() take array of pointers to channel data	12 years ago
Diego Biurrun	26301caaa1	x86: mmx2 ---> mmxext in asm constructs	12 years ago
Martin Storsjö	91ff4e83ca	x86: ac3dsp: Only refer to the ac3_downmix_sse symbol if it has been declared This fixes building without inline assembly. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Mans Rullgard	97cb9236cf	ac3: move ac3_downmix() from dsputil to ac3dsp Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	12 years ago
Diego Biurrun	29cfdd3767	x86: avcodec: Appropriately name files containing only init functions	12 years ago
Mans Rullgard	c318626ce2	x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	12 years ago
Justin Ruggles	95a98ab3f0	ac3dsp: simplify x86 versions of ac3_max_msb_abs_int16 Simplifies the code by using cpuflags and a new macro. Also fixes the invalid use of the MMX2 pshufw operation in the MMX-only function.	13 years ago
Diego Biurrun	265980dabc	x86: Move some variable declarations below the appropriat #ifdef. This avoids some unused variable warnings with YASM disabled.	13 years ago
Justin Ruggles	f99a5ef92e	ac3dsp: add x86-optimized versions of ac3dsp.extract_exponents().	14 years ago
Justin Ruggles	6ca23db9cc	ac3enc: modify mantissa bit counting to keep bap counts for all values of bap instead of just 0 to 4. This does all the actual bit counting as a final step.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	0f999cfddb	ac3enc: add float_to_fixed24() with x86-optimized versions to AC3DSPContext and use in scale_coefficients() for the floating-point AC-3 encoder.	14 years ago
Michael Niedermayer	f7a5e7791d	Revert "ac3enc: add SIMD-optimized shifting functions for use with the fixed-point AC3 encoder" This reverts commit `cc4d3dd3e2`. revert at authors request due to better impementation being available Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago

Justin Ruggles	7539a1fee2	ac3enc: Add x86-optimized function to speed up log2_tab().
