[PATCH] D64713: [InstCombine] X *fast (C ? 1.0 : 0.0) -> C ? X : 0.0

[Jay Foad via Phabricator via llvm-commits]

================
Comment at: llvm/lib/Transforms/InstCombine/InstructionCombining.cpp:775
+    Value *V1 = SimplifyFPBinOp(Opcode, C, F, FMF, SQ.getWithInstruction(&I));
+    Value *V2 = SimplifyFPBinOp(Opcode, B, E, FMF, SQ.getWithInstruction(&I));
     if (V1 && V2)
----------------
Question to reviewers: would it be better to enhance SimplifyQuery / InstrInfoQuery to know about fast math flags, so that I don't have to pass FMF around explicitly?
