Subject: imdct36: mark SSE functions as using all 16 XMM registers.
X-Git-Tag: v9_beta1~3266
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=331e7c4cb34eb77451fbf84c604d717ed49abf15;p=platform%2Fupstream%2Flibav.git

imdct36: mark SSE functions as using all 16 XMM registers.

On x86-64, it indeed uses all 16 registers (and on x86-32, this gets
clipped to 8). Not marking it properly causes callers of this function
to fail randomly because of XMM register clobbering.
