[FFmpeg-devel] [PATCH] swscale: execute sfence and emms depending on runtime flags

[Ramiro Polla]

Hi,

Attached patch is the start of the swscale{,_template}.c split into
arch subdirs. There will eventually be only one swScale(), so this bit
needs to be decided on runtime.

If anyone wants to check out what the whole thing looks like
"finished", go to http://ramiro.arrozcru.org/libswscale . It passes
regression tests on x86, x86 with gpl, x86 with gpl and no mmx2, x86
with gpl and no 3dnow, and altivec.
