Janne Grunau	e2710e790c	arm: add a cpu flag for the VFPv2 vector mode The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu implementations do not support it in hardware. Vector mode code will depending the OS either be emulated in software or result in an illegal instruction on cpus which does not support it. This was not really problem in practice since NEON implementations of the same functions are preferred. It will however become a problem for checkasm which tests every cpu flag separately. Since this is a cpu feature newer cpu do not support anymore the behaviour of this flag differs from the other flags. It can be only activated by runtime cpu feature selection.	9 years ago

Michael Niedermayer	1e519b9d40	avutil: turn arm setend into a cpuflag this allows disabling and enabling it it also prevents crashes if vfpv3 and neon are disabled which previously would have enabled the flag And last but not least one can enable setend on cpus like cortex-a8 where its fast but disabled by default Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 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

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.

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
