[PATCH] D36656: [SCCP] Propagate integer range information in IPSCCP (WIP).

[Florian Hahn via Phabricator via llvm-commits]

fhahn updated this revision to Diff 112577.
fhahn added a comment.

Update the patch to support all predicates through ConstantRange functions and use a SmallPtrSet to keep track of ICmp instructions to delete (deleting them straight away would invalidate iterators). It would be great if you could have another look now. If that approach is sensible I'll add another review that moves LVILatticeVal to a separate module properly.
