================
Comment at: clang/lib/AST/ParentMapContext.cpp:231
+  template <typename MapNodeTy, typename MapTy>
+  void MarkChild(MapNodeTy MapNode, MapTy *Parents) {
+    if (ParentStack.empty())
----------------
can we make some comments explaining what this method does?  I think I have a vague understanding, but would be helpful to have some documentation.
