[PATCH] D119854: [SimplifyCFG][CVP][PhaseOrdering] Defer lowering switch into an integer range comparison and branch until the end of function simplification pipeline

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

This looks sensible to me.

Would it be sufficient to only block this transform in the very first (pre-inlining) SimplifyCFG run, which I think would allow IPSCCP to fold it? Or does only CVP handle this case?
