[Allen zhong via Phabricator via cfe-commits]

Allen added inline comments.
Herald added a project: All.


================
Comment at: clang/lib/CodeGen/CGExprScalar.cpp:3386
+    FMulAdd = Builder.CreateConstrainedFPCall(
+        CGF.CGM.getIntrinsic(llvm::Intrinsic::experimental_constrained_fmuladd,
+                             Addend->getType()),
----------------
Sorry, I'm not familiar with the optimization of the clang front end. 
I'd like to ask, is this optimization supposed to assume that all the backends have instructions like Fmuladd?
