MMX code tries to read from SSE2 register (in /vp8/common/x86/postproc_mmx.asm) #531

Closed GoogleCodeExporter closed 9 years ago

In mentioned file there's something like:

movq        [rdi],      xmm1

It is obviously a typo, there should be:

movq        [rdi],      mm1

instead.

(Of course current code breaks on CPUs without at least SSE2 due to that typo).

I've attached a patch for this bug.
