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	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

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>	12 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.	12 years ago
Mans Rullgard	e346176de9	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

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.

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.

Justin Ruggles	eba586b0d9	Add a CPU flag for the Atom processor. The Atom has SSSE3 support, which is useful in many cases, but sometimes the SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally faster on other processors supporting SSSE3. This flag allows for selectively disabling certain SSSE3 functions on the Atom.	14 years ago

Mans Rullgard	f1f792117f	x86: use raw opcode for xgetbv instruction This allows the CPU detection to work with assemblers not supporting the xgetbv mnemonic. These include clang and some BSD versions. All AVX code will be written for yasm, where the main assembler is not involved.
