[PATCH] D118480: [clang][dataflow] Merge distinct pointer values in Environment::join

[Gábor Horváth via Phabricator via cfe-commits]

xazax.hun added inline comments.


================
Comment at: clang/lib/Analysis/FlowSensitive/DataflowEnvironment.cpp:114
 
+    if (auto *FirstVal = dyn_cast<PointerValue>(Val)) {
+      auto *SecondVal = cast<PointerValue>(It->second);
----------------
Shouldn't we ensure that `operator==` return true when we have two `PointerValue`s with the same pointee above? That would make this piece of code redundant.
