[PATCH] D158291: [PoC][WIP] Add an AArch64 specific pass for loop idiom recognition

[David Sherwood via Phabricator via llvm-commits]

david-arm updated this revision to Diff 556252.
david-arm added a comment.

- Added more checks that the icmp predicates are correct (EQ) and ensure that the true/false block ordering for the branches are what we expect.
- Added more negative test cases for bad icmps, bad branches and bad load types.
