Kieran Kunhya	4d6ee07255	libavutil: x86: Add AVX2 capable CPU detection. Patch based on x264's AVX2 detection Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Diego Biurrun	79aec43ce8	x86: Add and use more convenience macros to check CPU extension availability	11 years ago
Diego Biurrun	8410d6e93c	avutil: Refactor CPU extension availability macros	11 years ago
Diego Biurrun	1f6d86991f	x86: Add YASM implementations of cpuid and xgetbv from x264 This allows detecting CPU features with builds that have neither gcc inline assembly nor the right compiler intrinsics enabled.	12 years ago
Diego Biurrun	f82c4fb27f	x86: Add convenience macros to check for CPU extensions and flags	12 years ago
Måns Rullgård	9275438a19	Clean up av_get_cpu_flag() Instead of defining functions in per-arch header files included by the main cpu.c, define them normally and call them from the generic one. Originally committed as revision 25084 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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
Ronald S. Bultje	6526976f0c	Remove FF_MM_SSE2/3 flags for CPUs where this is generally not faster than regular MMX code. Examples of this are the Core1 CPU. Instead, set a new flag, FF_MM_SSE2/3SLOW, which can be checked for particular SSE2/3 functions that have been checked specifically on such CPUs and are actually faster than their MMX counterparts. In addition, use this flag to enable particular VP8 and LPC SSE2 functions that are faster than their MMX counterparts. Based on a patch by Loren Merritt <lorenm AT u washington edu>. Originally committed as revision 24340 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	6b4343616c	Rename FF_MM_MMXEXT to FF_MM_MMX2, for both clarity and consistency with libswscale. Originally committed as revision 18330 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
David Conrad	710441c2f6	Add SSE4 detection support Originally committed as revision 18302 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Zuxy Meng	d05f808dc9	Remove CPUID availability check on AMD64 as it's architectural. Originally committed as revision 17543 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Aurelien Jacobs	b250f9c66d	Change semantic of CONFIG_, HAVE_ and ARCH_*. They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	1bb04d5a44	configure: allow to disable sse code. Based on patch by Michael Kostylev <mik at it-1 dot ru> Originally committed as revision 16490 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	a6493a8fbd	Rename libavcodec/i386/ --> libavcodec/x86/. It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	35d0c2173c	Replace pushf/popf by explicit pushfl/popfl (32 bit) or pushfq/popfq (x86_64), to fix generated code on ICC 11.0. Originally committed as revision 15935 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Pettenò	be449fca79	Convert asm keyword into __asm__. Neither the asm() nor the __asm__() keyword is part of the C99 standard, but while GCC accepts the former in C89 syntax, it is not accepted in C99 unless GNU extensions are turned on (with -fasm). The latter form is accepted in any syntax as an extension (without requiring further command-line options). Sun Studio C99 compiler also does not accept asm() while accepting __asm__(), albeit reporting warnings that it's not valid C99 syntax. Originally committed as revision 15627 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Ramiro Polla	40d0e665d0	Do not misuse long as the size of a register in x86. typedef x86_reg as the appropriate size and use it instead. Originally committed as revision 13081 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Reimar Döffinger	78d3d94f14	__asm __volatile -> asm volatile, improves code consistency and works (as far as that is possible) with the Sun C compiler. Originally committed as revision 12188 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
