[PATCH] D71152: [analyzer] Keep track of escaped locals.

[Artem Dergachev via Phabricator via cfe-commits]

NoQ added a comment.

I've been hiding these internal traits in ExprEngine lately but i don't have a strong preference. I don't see any immediate need to expose this info to the checkers, nor do i see a need to actively hide it.

And, yeah, needs dead region cleanup :)



================
Comment at: clang/lib/StaticAnalyzer/Core/ProgramState.cpp:229-233
+    for (const MemRegion *R : Invalidated) {
+      if (!R->hasStackStorage())
+        continue;
+      newState = newState->add<EscapedLocals>(R);
+    }
----------------
Ok, so how do we want to deal with non-base regions? I think for the purposes of escaping we try to stick to per-base-region granularity (cf. the C-style linked list example). This is also going to be nice because the amount of regions we'll have to track is going to be more limited and there's going to be no problem of representing the same region in multiple different ways.
