[PATCH] D12537: [MergeFuncs] Efficiently defer functions on merge

[JF Bastien via llvm-commits]

jfb added a comment.

> The current implementation (which uses the ordering to find the right node) sometimes missed functions, which most likely occurs due to functions changed before they are actually removed from the tree, changing the implicit invariant of the tree that it's elements remain in a stable order.


Can you clarify this? Is that a new thing? It at least seems like something that should be in a FIXME.
