Diego Biurrun	46bacb5cc6	x86: Consistently use cpu flag detection macros in places that still miss it	11 years ago
Diego Biurrun	e998b56362	x86: avcodec: Consistently structure CPU extension initialization	12 years ago
Diego Biurrun	3ac7fa81b2	Consistently use "cpu_flags" as variable/parameter name for CPU flags	12 years ago
Diego Biurrun	643e433bf7	mpegaudiosp: More consistent names for ppc/x86 optimization files	12 years ago
Diego Biurrun	218aefce44	dsputil: Move LOCAL_ALIGNED macros to libavutil	12 years ago
Diego Biurrun	c9f933b5b6	Add av_cold attributes to arch-specific init functions	12 years ago
Janne Grunau	f101eab1be	x86: call most of the x86 dsp init functions under if (ARCH_X86) Rename the called dsp init functions to *_init_x86.	13 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.	13 years ago
Diego Biurrun	1169f0d0af	x86: more specific checks for availability of required assembly capabilities	13 years ago
Diego Biurrun	ec36aa6944	x86: Fix linking with some or all of yasm, mmx, optimizations disabled Some optimized template functions reference optimized symbols, so they must be explicitly disabled when those symbols are unavailable.	13 years ago
Diego Biurrun	bcc45d6348	x86: avcodec: Drop silly "_mmx" suffixes from filenames	13 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>	13 years ago
Ronald S. Bultje	bde73f28af	mpegaudio: bury inline asm under HAVE_INLINE_ASM.	13 years ago
Christophe GISQUET	f3e084909b	mpegaudio: replace memcpy by SIMD code By replacing memcpy with an unrolled loop using the alignment knowledge it has, some speedup can be obtained. Before (gcc 4.6.1): ~400 cycles After: ~370 cycles Overall, around 2% speed increase when decoding a 2400s mp3 to f32le. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Vitor Sessak	39df0c434c	mpegaudiodec: optimized iMDCT transform Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Mans Rullgard	c4f5c2d6f4	Move some mpegaudio functions to new mpegaudiodsp subsystem This separation allows these functions to be used in a cleaner fashion from other codecs (e.g. qdm2) and simplifies creating optimised versions of them. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Stefano Sabatini	c6c98d0897	Move mm_support() from libavcodec to libavutil, make it a public function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	7160bb716b	Rename FF_MM_ symbols related to CPU features flags as AV_CPU_FLAG_ symbols, and move them from libavcodec/avcodec.h to libavutil/cpu.h. Originally committed as revision 25040 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c0ec9918b0	Remove global mm_flags variable Originally committed as revision 24909 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	89c7d8058c	Fix compilation on x64. Originally committed as revision 23753 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	57dbd12b6d	Fix asm constraints in apply_window() Originally committed as revision 23752 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
