[PATCH] D88059: [Coroutine] Split PHI Nodes in `cleanuppad` blocks in a way that obeys EH pad rules

[Xun Li via Phabricator via llvm-commits]

lxfind added inline comments.


================
Comment at: llvm/lib/Transforms/Coroutines/CoroFrame.cpp:1211
+    if (auto *CatchSwitch = dyn_cast<CatchSwitchInst>(Pred->getTerminator())) {
+      return CatchSwitch->getUnwindDest() == BB;
+    }
----------------
Should this be
```
if (CatchSwitch->getUnwindDest() == BB)
  return true;
```
?
Or is it impossible to have multiple predecessors with `CatchSwitch` all pointing to BB somehow?
