[MPlayer-dev-eng] [RFC] emms/sfence in fast memcpy()

[Michael Niedermayer]

Hi

current fast memcpy (agp and normal) variants do emms and sfence at the
end, this is slow and particualry annoying if the copy is called once per
line which it is in many cases
i think that something should be done about that, though iam not
volunteering to do the work

if we didnt do this silly redefine memcpy() then this would be easier ...
a mp/av_memcpy() could simply leave the emms/sfence to the caller
