--- Comment #2 from Marc Glisse <marc.glisse at normalesup dot org> 2011-10-22 17:01:51 UTC --- (In reply to comment #1) > This looks similar to PR 34283, a RA problem. Ah, indeed. I also had a function that ended with: vmovapd %xmm1, %xmm0 vmaxpd %xmm2, %xmm0, %xmm0 vzeroupper ret which looks related too. Thanks for the link.
