[Dmitry Venikov via Phabricator via llvm-commits]

Quolyk added inline comments.


================
Comment at: lib/Target/X86/X86ISelLowering.cpp:7862
     return AddSub;
+  if (SDValue FMSubAdd = lowerToFMSubAdd(BV, Subtarget, DAG))
+    return FMSubAdd;
----------------
I added that if statement, but I have problems testing this, specifically I don't know how to test this
