[PATCH] D154695: [Coroutines] Add an O(n) algorithm for computing the cross suspend point information.

[Chuanqi Xu via Phabricator via llvm-commits]

ChuanqiXu added a comment.

Sorry. I still can't understand the algorithm yet. e.g., why is it sufficient to iterate the graph 3 times? How do we identity loops in the algorithm? Could you elaborate it in the code?
