[PATCH] D26045: [cfi] Fix weak functions handling.

[Peter Collingbourne via llvm-commits]

pcc added inline comments.


================
Comment at: lib/Transforms/IPO/LowerTypeTests.cpp:766
+    if (auto *GV = dyn_cast<GlobalVariable>(U))
+      Out.push_back(GV);
+    else if (auto *C2 = dyn_cast<Constant>(U))
----------------
Is this correctly handling the case where an initializer contains multiple references to a weak undef?
