[PATCH] D127699: [InstCombine] Don't slice up PHIs when pred BB has catchswitch

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Transforms/InstCombine/InstCombinePHI.cpp:1128
+    for (auto *Pred : PN->blocks())
+      if (isa<CatchSwitchInst>(Pred->getFirstNonPHI()))
+        return nullptr;
----------------
The correct way to check this is whether `getFirstInsertionPt()` is `end()`.
