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	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

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	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.	13 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.	13 years ago
Diego Biurrun	f82c4fb27f	x86: Add convenience macros to check for CPU extensions and flags	13 years ago
Diego Biurrun	17337f54c0	x86: Split inline and external assembly #ifdefs	13 years ago

Loren Merritt	7a1944b907	vf_hqdn3d: x86 asm 13% faster on penryn, 16% on sandybridge, 15% on bulldozer Not simd; a compiler should have generated this, but gcc didn't.	13 years ago
Justin Ruggles	6092dafb5a	lavr: x86: optimized 6-channel s16 to fltp conversion	13 years ago
Mans Rullgard	5b170c0bea	x86: remove FASTDIV inline asm GCC 4.3 and later do the right thing with the plain C code. Earlier versions in 32-bit mode generate one extra instruction, needlessly zeroing what would be the high half of the shifted value. At least two gcc configurations miscompile the inline asm in some situations. In 64-bit mode, all gcc versions generate imul r64, r64 followed by shr. On Intel i7 and later, this imul is faster 32-bit mul. On older Intel and all AMD, it is slightly slower. On Atom it is much slower. Considering where the FASTDIV macro is used, any overall negative performance impact of this change should be negligible. If anyone cares, they should file a bug against gcc and get the instruction selection fixed. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

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
