[PATCH] D74263: [ValueTracking] Improve isKnownNonNaN() to recognize zero splats.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:4781
+  if (isa<ConstantAggregateZero>(V) &&
+      V->getType()->getScalarType()->isFloatingPointTy())
+    return true;
----------------
I don't think you need the FP type check
