[PATCH] D75526: [X86] Disable commuting for the first source operand of zero masked scalar fma intrinsic instructions.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/test/CodeGen/X86/avx512-intrinsics.ll:5838
+; X86-NEXT:    kmovw %eax, %k1
+; X86-NEXT:    vfmadd132ss {{.*#+}} xmm0 = (xmm0 * mem) + xmm1
+; X86-NEXT:    retl
----------------
(sidenote) losing the mask register from the asm comment is really bad.......
