[PATCH] D30774: [SimplifyCFG] Merging duplicated basic blocks

[Kenneth Hilmersson via Phabricator via llvm-commits]

KennethH added a comment.

We have some cases where a modified version of this patch (modified to also allow optimizing non-branch CFG edges) makes a **huge** difference in compile time and code size.
The code contains large switch cases where lots of the case BB are equal.

I have a question if this wouldn´t be a good optimization to have in the framework after all?
