[PATCH] D19075: mergefunc: avoid merge with loop metadata

[Hal Finkel via llvm-commits]

hfinkel added a comment.

Do we not unqiue MDNodes? This seems like a lot of code for what I would have thought should be: Compare the pointer equality all MDNode operands except the first (because the first is the unique loop id).
