[PATCH] D143505: [InstSimplify] fix/improve folding with an SNaN operand

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Analysis/InstructionSimplify.cpp:5337
+  const APFloat &NaN = cast<ConstantFP>(In)->getValue();
+  return ConstantFP::get(Ty, scalbn(NaN, 0, APFloat::rmNearestTiesToEven));
 }
----------------
Probably should add / expose a makeQuiet if this is going to spread more places
