[FFmpeg-devel] [RFC] clobbers for XMM registers

[Reimar Döffinger]

Hello,
this is not suitable by far (among other things, ugly parts, split asm code
where a clobber is likely to introduce bugs, only tested to compile,
did not find a nice "dummy" clobber constraint - particularly important since
I suspect older gccs won't accept %xmm clobbers, ...).
But since I don't have much time to work on it, I wanted to dump it
to get some comments and ideas.
