================
Comment at: llvm/lib/Passes/PassBuilder.cpp:625
- if (PTO.Coroutines)
- FPM.addPass(CoroElidePass());
-
----------------
we can still keep this here right? since we'll run the function simplification pipeline on the split coroutine
also, this should be duplicated in `buildFunctionSimplificationPipeline()`
================
Comment at: llvm/lib/Transforms/Coroutines/CoroSplit.cpp:1710
removeCoroEnds(Shape, &CG);
- postSplitCleanup(F);
+ removeUnreachableBlocks(F);
----------------
this could regress coroutines under the legacy PM behavior since we don't run `postSplitCleanup()` here? but maybe we don't care about the legacy PM so much anymore.
================
Comment at: llvm/lib/Transforms/Coroutines/CoroSplit.cpp:2004
+ UR.CWorklist.insert(&C);
+ for (Function *Clone : Clones)
+ UR.CWorklist.insert(CG.lookupSCC(CG.get(*Clone)));
----------------
are all `Clones` guaranteed to be in different SCC?
