| * x86: get_cpu_flags: add necessary ifdefs around function bodyDiego Biurrun2012-10-04
| | | | | | | | | | | | | | 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.
| * x86: Drop CPU detection intrinsicsDiego Biurrun2012-10-04
| | | | | | | | | | | | 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.
| * x86: Add YASM implementations of cpuid and xgetbv from x264Diego Biurrun2012-10-04
| | | | | | | | | | This allows detecting CPU features with builds that have neither gcc inline assembly nor the right compiler intrinsics enabled.

| | | | | | | | | | | | | | 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.
