Ronald S. Bultje	96c9cc1094	x86inc: sync to latest version from x264.	12 years ago
Justin Ruggles	79687079a9	x86: add support for fmaddps fma4 instruction with abstraction to avx/sse	12 years ago
Ronald S. Bultje	30b45d9c38	x86inc: automatically insert vzeroupper for YMM functions.	12 years ago
Loren Merritt	2cd1f5cadc	x86inc: modify ALIGN to not generate long nops on i586 Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Loren Merritt	705f3d4759	x86inc: support AVX abstraction for 2-operand instructions Add cvtdq2ps and cvtps2dq to the AVX instruction list. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Henrik Gramner	729f90e268	x86inc improvements for 64-bit Add support for all x86-64 registers Prefer caller-saved register over callee-saved on WIN64 Support up to 15 function arguments Also (by Ronald S. Bultje) Fix up our asm to work with new x86inc.asm. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Ronald S. Bultje	98b9da2ac7	x86inc: add *mp named argument support to DEFINE_ARGS.	13 years ago
Loren Merritt	0f53d0cf4b	x86inc: don't "bake" stack_offset in named arguments. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Haruhiko Yamagata	166f399377	x86inc: support yasm -f win64 flag also. This sets __OUTPUT_FORMAT__ to win64 instead of win32, even though both (through -m amd64) produce 64-bit binary code. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Henrik Gramner	9cf7385309	x86inc: allow manual use of WIN64_SPILL_XMM. Functions using INIT_MMX may still access XMM registers through direct means (xmm0-15). Therefore, they still need to be marked for clobber so they can be properly saved/restored. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	412b248edb	x86inc.asm: fix typo. Assemblers don't understand ! in %if statements.	13 years ago
Ronald S. Bultje	3b15a6d742	config.asm: change %ifdef directives to %if directives. This allows combining multiple conditionals in a single statement.	13 years ago
Vitor Sessak	39df0c434c	mpegaudiodec: optimized iMDCT transform Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Vitor Sessak	6b6ee58249	x86inc: Flag shufps as an floating-point instruction for the AVX emulation code. Without this, code like "shufps m0, m1, m2, 0xaa" would not work in CPUs not supporting SSE2. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Justin Ruggles	f2bd8a0786	x86inc: use sse versions of common macros instead of sse2 when applicable	13 years ago
Loren Merritt	2f7f2e4b41	Update x86inc.asm to latest x264 version, and add AVX symmetry. We keep INIT_AVX (for backwards compatibility). 3arg AVX ops with a memory arg can only have it in src2, whereas SSE emulation of 3arg prefers to have it in src1 (i.e. the mov). So, if the op is symmetric and the wrong one is memory, swap them.	13 years ago
Ronald S. Bultje	3a39195b1d	Move x86inc.asm to libavutil/. This allows using it in libswscale/ also.	13 years ago
Dave Yeo	d69f9a4234	Add support for a.out object format to assembler macros. This format is still used by e.g. OS/2. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Vitor Sessak	33cbfa6fa3	Update x86inc.asm from x264 to allow AVX emulation using SSE and MMX. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago
Loren Merritt	532e769701	sync yasm macros from x264 Originally committed as revision 24406 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	2966cc1849	Update x264asm header files to latest versions. Modify the asm accordingly. GLOBAL is now no longoer necessary for PIC-compliant loads. Originally committed as revision 23739 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	29e4edbbe7	sync yasm macros to x264 Originally committed as revision 20293 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	2f77923d72	simd add_hfyu_left_prediction 2.2x faster than C on conroe, 3.6x on penryn. 4-6% faster huffyuv decoding if using left or plane mode and yuv Originally committed as revision 20287 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
John Adcock	3f87f39cb8	Update x264 asm code to latest to add support for 64-bit Windows. Use the new x86inc features to support 64-bit Windows on all non-x264 nasm assembly code as well. Patch by John Adcock, dscaler.johnad AT googlemail DOT com. Win64 changes originally by Anton Mitrofanov. x86util changes mostly by Holger Lubitz. Originally committed as revision 19580 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
Jason Garrett-Glaser	40c7d0ae3c	Add automatic prefix handling to yasm functions. Does nothing now, but will be useful for porting x264 asm in the future. Originally committed as revision 16234 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Loren Merritt	bafad220a7	import yasm macros from x264 Originally committed as revision 14697 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
