This adds the NAN checks suggested in PR37776: https://bugs.llvm.org/show_bug.cgi?id=37776 If both operands to maxnum are NAN, that should get constant folded, so we don't have to handle that case. This is the same assumption as other FP ops in this function. Returning 'false' is always conservatively correct. Copying from the bug report: Currently, we have this for "when is cannotBeOrderedLessThanZero (mustBePositiveOrNaN) true for maxnum": L ------------------- | Pos | Neg | NaN | ------------------------ |Pos | x | x | x | ------------------------ R |Neg | x | | x | ------------------------ |NaN | x | x | x | ------------------------ The cases with (Neg & NaN) are wrong. We should have: L ------------------- | Pos | Neg | NaN | ------------------------ |Pos | x | x | x | ------------------------ R |Neg | x | | | ------------------------ |NaN | x | | x | ------------------------ Differential Revision: https://reviews.llvm.org/D50081 llvm-svn: 338716 |
