Diego Biurrun	5ab03e41e5	x86: h264dsp: Fix link failure with optimizations disabled With optimzations disabled compilers have trouble doing dead code elimination on 'if (foo && 0)' expressions, while 'if (0 && foo)' still works, so use the latter to avoid problems. Bug-Id: 707	11 years ago

Ronald S. Bultje	ce58642ed0	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: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Diego Biurrun	d8eda37080	x86: mmx2 ---> mmxext in function names	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

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
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

Ronald S. Bultje	b829b4ce29	h264: convert loop filter strength dsp function to yasm. This completes the conversion of h264dsp to yasm; note that h264 also uses some dsputil functions, most notably qpel. Performance-wise, the yasm-version is ~10 cycles faster (182->172) on x86-64, and ~8 cycles faster (201->193) on x86-32.	13 years ago

Reimar Döffinger	b223035511	Detect and check for CMOV. Some MMX-only CPUs do not have support for CMOV. All SSE/MMX2 CPUs should be fine, thus no check was added to those functions.

Daniel Kang	f3aa65af3a	h264/10bit: add HAVE_ALIGNED_STACK checks. Fixes regression in `836f47d34b` in ICC-10.x, since ICC<=11.0 doesn't align stack upon function calls. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
