the "sse" assembler used sse2 instructions with the exception of
1 or 2 functions that are only used in very rare cases.
it should be possible to change the macros so they produce something
that works on SSE cpus this would be slower for them though and be
a bit work.
A patch surely would be welcome.
in absence of a patch i might look into it too but first some fate
client that tests ffmpeg on sse only hardware would be needed
