Ronald S. Bultje	0c0828ecc5	x86: Use simple nop codes for <= sse (rather than <= mmx) The "CentaurHauls family 6 model 9 stepping 8" family of CPUs (flags: fpu vme de pse tsc msr cx8 sep mtrr pge mov pat mmx fxsr sse up rng rng_en ace ace_en) SIGILLs on long nop codes.

Diego Biurrun	4db96649ca	avutil: Ensure that emms_c is always defined, even on non-x86	12 years ago
Diego Biurrun	ab441e20ff	avutil: Move emms code to x86-specific header	12 years ago
Ronald S. Bultje	d56668bd80	floatdsp: move scalarproduct_float from dsputil to avfloatdsp. This makes the aac decoder and all voice codecs independent of dsputil.	12 years ago
Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.	12 years ago
Ronald S. Bultje	55aa03b9f8	floatdsp: move vector_fmul_add from dsputil to avfloatdsp.	12 years ago
Martin Storsjö	f4facd2ce7	x86: Add a Yasm-based emms() replacement This provides a fallback when building with Yasm enabled, but neither inline assembly, nor the _mm_empty intrinsic are available or enabled. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Diego Biurrun	d633d12b2c	x86inc: Add cvisible macro for C functions with public prefix This allows defining externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Diego Biurrun	ef5d41a553	x86inc: Rename "program_name" to "private_prefix" The new name is more descriptive and will allow defining a separate public prefix for externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Martin Storsjö	973b4d44f1	float_dsp: Add #ifdef HAVE_INLINE_ASM around vector_fmul_window This fixes builds on 64bit MSVC. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Janne Grunau	0995ad8db4	x86inc: fully concatenate tokens to fix macro expansion for nasm Fixes build errors with nasm introduced in `6f40e9f070` for stack memory alignment. Noticed by BugMaster.	12 years ago
Ronald S. Bultje	140367aff9	x86inc: fix stack alignment on win64 Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	6f40e9f070	x86inc: support stack mem allocation and re-alignment in PROLOGUE Use this in VP8/H264-8bit loopfilter functions so they can be used if there is no aligned stack (e.g. MSVC 32bit or ICC 10.x). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Justin Ruggles	1c012e6bfb	x86: float_dsp: fix loading of the len parameter on x86-32	12 years ago
Justin Ruggles	ecc8b02194	x86: float_dsp: fix compilation of ff_vector_dmul_scalar_avx() on x86-32 Signed-off-by: Janne Grunau <janne-libav@jannau.net>	12 years ago
Justin Ruggles	b30a363331	x86: af_volume: add SSE2/SSSE3/AVX-optimized s32 volume scaling	12 years ago
Justin Ruggles	ac7eb4cb20	float_dsp: add vector_dmul_scalar() to multiply a vector of doubles Include x86-optimized versions for SSE2 and AVX.	12 years ago
Diego Biurrun	490df522c7	x86: cpu: Drop unused HAVE_RWEFLAGS condition The test for rweflags was dropped in a previous commit.	12 years ago

Diego Biurrun	26301caaa1	x86: mmx2 ---> mmxext in asm constructs	12 years ago
Diego Biurrun	2b479bcab0	build: Drop AVX assembly ifdefs An assembler able to cope with AVX instructions is now required.	12 years ago
Diego Biurrun	f0d124f005	x86inc: Set program_name outside of x86inc.asm This reduces the local difference to the x264 upstream version.	12 years ago
Diego Biurrun	4b60fac419	x86: PALIGNR: port to cpuflags	12 years ago
Diego Biurrun	dbb37e7711	x86: PABSW: port to cpuflags	12 years ago

Diego Biurrun	26f01bd106	x86: PMINUB: port to cpuflags	12 years ago
Diego Biurrun	61bc2bc7d4	x86util: Add cpuflags_mmxext alias for cpuflags_mmx2 "mmxext" is a more sensible name and more common in outside projects.	12 years ago
Diego Biurrun	012f73e271	x86inc: Only define program_name if the macro is unset This allows overriding the value from outside of the file.	12 years ago
Dave Yeo	9c167914a1	x86: Fix assembly with NASM Unlike YASM, NASM only looks for include files in the current directory, not in the directory that included files reside in. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Diego Biurrun	588fafe7f3	x86: MMX2 ---> MMXEXT in macro names	12 years ago
Diego Biurrun	6860b4081d	x86: include x86inc.asm in x86util.asm This is necessary to allow refactoring some x86util macros with cpuflags.	12 years ago
Ronald S. Bultje	08b028c18d	Remove INIT_AVX from x86inc.asm.	12 years ago
Diego Biurrun	a7329e5fc2	x86: get_cpu_flags: add necessary ifdefs around function body ff_get_cpu_flags_x86() requires cpuid(), which is conditionally defined elsewhere in the file. Surrounding the function body with ifdefs allows building even when cpuid is not defined. An empty cpuflags mask is returned in this case.	12 years ago
Diego Biurrun	f6fbce761e	x86: Drop CPU detection intrinsics Now that there is CPU detection in YASM, there will always be one of inline or external assembly enabled, which obviates the need to fall back on CPU detection through compiler intrinsics.	12 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	54b243141e	x86: cpu: Break out test for cpuid capabilities into separate function	12 years ago
Diego Biurrun	cc5e9e5ff0	x86: ff_get_cpu_flags_x86(): Avoid a pointless variable indirection	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
Justin Ruggles	7327525997	x86: float_dsp: fix ff_vector_fmac_scalar_avx() on Win64 The SWAP macro does not work for explicit xmm/ymm usage, so instead just move the scalar value from xmm2 to xmm0.	12 years ago
Diego Biurrun	f82c4fb27f	x86: Add convenience macros to check for CPU extensions and flags	12 years ago
Diego Biurrun	17337f54c0	x86: Split inline and external assembly #ifdefs	12 years ago
