================
Comment at: llvm/lib/IR/Value.cpp:612-613
       V = cast<GlobalAlias>(V)->getAliasee();
+    } else if (StripKind == PSK_ZeroIndicesAndLocalAliases &&
+               isa<GlobalAlias>(V) && cast<GlobalAlias>(V)->hasLocalLinkage()) {
+      V = cast<GlobalAlias>(V)->getAliasee();
----------------
I wonder if it would be safe to power up all of the other versions of pointer stripping to look through local aliases.
