* Detect and check for CMOV.Reimar Döffinger2012-02-121-0/+2
| | | | | | | | | 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. See also https://sourceforge.net/tracker/?func=detail&aid=3358347&group_id=205275&atid=992986 Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

| * x86 cpuid: set vendor union members separatelySean McGovern2011-12-081-1/+4
| | | | | | | | | | | | | | | | | | 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. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

| * Add a CPU flag for the Atom processor.Justin Ruggles2011-03-221-2/+10
| | | | | | | | | | | | | | 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.

* Clean up av_get_cpu_flag()Måns Rullgård2010-09-091-0/+123
Instead of defining functions in per-arch header files included by the main cpu.c, define them normally and call them from the generic one. Originally committed as revision 25084 to svn://svn.ffmpeg.org/ffmpeg/trunk
