[PATCH] D116952: [ConstantFolding] Respect denormal handling mode attributes when folding instructions

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

ConstantFoldBinaryOpOperands has other callers; are you planning to fix each of them separately?

Assuming IEEE denormal handling if we can't find the parent Function seems a bit dubious, but maybe it's the best we can do for now.  It's not clear to me how this interacts with floating-point constant expressions (e.g. ConstantExpr::getFAdd).  I guess we could just kill off floating-point constant expressions, since they aren't really useful in practice, but that's a non-trivial effort.
