[Daniel Berlin via Phabricator via llvm-commits]

dberlin added inline comments.


================
Comment at: lib/Transforms/Utils/SSAUpdater.cpp:218
 
+void SSAUpdater::UpdatePHIDebugInfo(PHINode *PHI) {
+  LLVMContext &C = PHI->getParent()->getContext();
----------------
This looks really badly n^2 per call.
Is there really no faster way?
