[Sanjay Patel via Phabricator via llvm-commits]

spatel added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp:7980
 
+  auto IsConstantNonZero = [](SDValue N) {
+    if (auto *Input = dyn_cast<ConstantFPSDNode>(N))
----------------
Is this different than 
  auto *C = isConstOrConstSplatFP(N));
  return C && C->isZero();
