[PATCH] D90591: [ARM] Introduce t2DoLoopStartTP

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

Searching at the pre-ra level seems simple enough so long as we are in SSA form, and there are extra things I would like to add at the same point if I can makes sure they work. Doing those post-isel has some benefits in making sure we know the instructions we are looking at. Things like reverting calls is easier to do at this point (as it's easier to make sure we catch all calls).
