[PATCH] D67564: [IR] allow fast-math-flags on phi of FP values

[Michael Berg via Phabricator via llvm-commits]

mcberg2017 added a comment.

WRT divergent phi FMF, if you wanted to be pessimistic you could do an intersection(and), doing an inclusion(or) might include too much.  Either way behavior would change.  The intersection already has other prior context in FMF.
