[PATCH] D156850: [NFC][Coroutines] Use a reverse post-order to guide the computation about cross suspend infomation to reach a fixed point faster.

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added inline comments.


================
Comment at: llvm/lib/Transforms/Coroutines/CoroFrame.cpp:235-236
 
     // We don't need to count the predecessors when initialization.
     if constexpr (!Initialize)
       // If all the predecessors of the current Block don't change,
----------------
Well we should definitely check the predecessors even in Initialization now, in an RPO order we should have nearly all of them computed already (everything except for backedges).
