Mans Rullgard	070a402b60	x86: move MANGLE() and related macros to libavutil/x86/asm.h These x86-specific macros do not belong in generic code. Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Mans Rullgard	edd8226795	x86: fix build with nasm 2.08 It appears that something goes wrong in old nasm versions when the %+ operator is used in the last argument of a macro invocation and this argument is tested with %ifdef within the macro. This patch rearranges the macro arguments such that the %+ operator is never used in the last argument.	13 years ago
Mans Rullgard	180d43bc67	x86: use nop cpu directives only if supported nasm does not support 'CPU foonop' directives. This adds a configure test for the directive and uses it only if supported. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	7238265052	x86: fix rNmp macros with nasm For some reason, nasm requires this. No harm done to yasm. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	a3df4781f4	x86: add colons after labels nasm prints a warning if the colon is missing. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 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.	13 years ago
Diego Biurrun	ca844b7be9	x86: Use consistent 3dnowext function and macro name suffixes Currently there is a wild mix of 3dn2/3dnow2/3dnowext. Switching to "3dnowext", which is a more common name of the CPU flag, as reported e.g. by the Linux kernel, unifies this.	13 years ago
Loren Merritt	f8d8fe255d	x86inc: clip num_args to 7 on x86-32. This allows us to unconditionally set the cglobal num_args parameter to a bigger value, thus making writing yasm code even easier than before. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	96c9cc1094	x86inc: sync to latest version from x264.	13 years ago
Justin Ruggles	79687079a9	x86: add support for fmaddps fma4 instruction with abstraction to avx/sse	13 years ago
Ronald S. Bultje	30b45d9c38	x86inc: automatically insert vzeroupper for YMM functions.	13 years ago
Jason Garrett-Glaser	85a3c19ed1	dsputil: x86: add SHUFFLE_MASK_W macro Simplifies pshufb masks that operate on words.	13 years ago
Ronald S. Bultje	358d854df8	x86/cpu: implement get/set_eflags using intrinsics Signed-off-by: Diego Biurrun <diego@biurrun.de> Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Ronald S. Bultje	07b287020c	x86/timer: implement an intrinsic-based version for rdtsc (AV_READ_TIME).	13 years ago
Loren Merritt	4d4752366f	x86inc: add SPLATB_LOAD, SPLATB_REG, PSHUFLW macros Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 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
Mans Rullgard	889c1ec4cc	x86: cpu: clean up check for cpuid instruction support This adds macros for accessing the EFLAGS register and uses these instead of coding the entire check in inline asm. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	963cdf39b4	x86: cpu: whitespace (mostly) cosmetics This adds whitespace around operators, aligns line continuation backslashes, and breaks long lines. Also fixes an ifdef halfway through a statement. The one line of duplication this saved is not worth the ugliness. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	8123e0901f	x86: place some inline asm under #if HAVE_INLINE_ASM Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Justin Ruggles	82b2df9790	float_dsp: add x86-optimized functions for vector_fmac_scalar()	13 years ago
Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Vitor Sessak	4a301706fd	x86: Avoid movs on BUTTERFLYPS when in AVX mode Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Justin Ruggles	5cc6d5244d	lavr: replace the SSE version of ff_conv_fltp_to_flt_6ch() with SSE4 and AVX 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.	13 years ago
Justin Ruggles	c8af852b97	Add libavresample This is a new library for audio sample format, channel layout, and sample rate conversion.	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
Diego Biurrun	baaab6069a	build: Move all arch OBJS declarations into arch subdirectory Makefiles.	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	7e4d9d5d45	win64: add a XMM clobber test configure option. This will be useful to test more aggressively for failures to mark XMM registers as clobbered in Win64 builds, and prevent regressions thereof. Based on a patch by Ramiro Polla <ramiro.polla@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
Mans Rullgard	5b0d35eaed	x86: bswap: remove test for bswap instruction Firstly, this test never worked as intended, always reporting success. Secondly, bswap is available from 486 onward and can thus be assumed present. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	f64c2e710f	bswap: make generic implementation more compiler-friendly With these changes, gcc 4.5 and later recognise it as a bswap and use the proper instructions on ARM and x86. On x86, the 16-bit bswap is recognised from gcc 4.1. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Sean McGovern	be0675ce67	x86 cpuid: set vendor union members separately Solaris Studio (suncc) has difficulty with filling in members of a union. Instead, let's retrieve and store the cpuid() results separately. This is still a compiler bug, however this fix does not cause a regression on other platforms. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	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
Justin Ruggles	4e8e262476	fmtconvert: port int32_to_float_fmul_scalar() x86 inline asm to yasm	13 years ago
Jason Garrett-Glaser	96a59cf37b	x86: XOP/FMA4 CPU detection support	13 years ago
Sean McGovern	5938e02185	cpu detection: avoid a signed overflow 1<<31 overflows because 1 is signed, so force it to unsigned. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	38e06c2969	Move clipd macros to x86util.asm. This allows sharing them between multiple .asm files.	14 years ago
Ronald S. Bultje	b2c087871d	Move x86util.asm from libavcodec/ to libavutil/. This allows using it in swscale also.	14 years ago
