[PATCH] D49499: [X86] Prefer unpckhpd over movhlps in isel for fake unary cases

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: test/CodeGen/X86/combine-fcopysign.ll:202
 ; SSE-NEXT:    shufps {{.*#+}} xmm3 = xmm3[3,1],xmm2[2,3]
-; SSE-NEXT:    movaps {{.*#+}} xmm7
+; SSE-NEXT:    movaps {{.*#+}} xmm7 = [nan,nan]
 ; SSE-NEXT:    movaps %xmm0, %xmm2
----------------
Don't include the nan comment - it'll fail on windows builds
