* avutil: turn arm setend into a cpuflagMichael Niedermayer2014-08-13
| | | | | | | | | | | 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>

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

| * Add a CPU flag for the Atom processor.Justin Ruggles2011-03-22
| | | | | | | | | | | | | | 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.
