[PATCH] D122959: [ARM] Only update the successor edges for immediate predecessors of PrologueMBB.

[Zhiyao Ma via Phabricator via llvm-commits]

ZhiyaoMa98 added a comment.

I would like to add a test, but I do not know how. My understanding is that I will need to create an example that PrologueMBB has non-immediate predecessors. Is there any example I can follow? Thanks!
