[PATCH] D75341: [BFI] Use CallbackVH to notify BFI about deletion of basic blocks

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

Alternatively I think it would be reasonable to expect the passes claiming to preserve BFI to notify BFI about deleted/added blocks, like we do for many other analysis. Do you have any idea of how much effort that would take?
