The test should be either changed to really emit vpmacsdql, or asm scan should be adjusted. > Tests that now work, but didn't before: > > gcc.target/i386/xop-mul-1.c execution test Yes this one should be fixed with the patch. If the change vmpacsdql -> vpmuldq is OK with you, I can commit the patch, but I'd ask you for full bootstrap/regression test.
