[PATCH] D45299: API to update MemorySSA for cloned blocks.

[Alina Sbirlea via Phabricator via llvm-commits]

asbirlea added a comment.

Update patch with the following:

- Fix a few bugs that were triggered by tests in SimpleLoopUnswitch
- Slightly modify current APIs and add a couple APIs motivated by SimpleLoopUnswitch
- Add APIs to delete blocks (SimpleLoopUnswitch modifies the CFG heavily) and MemoryPhi entries.

This is becoming a pretty complex patch, so if you think at least the removeBlocks/delete from MPhis should be in a separate patch, I can split them.

I will upload the patch that updates MSSA in SimpleLoopUnswitch as a dependecy as well.

As far as testing, all tests pass with the sequence of patches, but I am looking into additional testing.
