================
Comment at: llvm/lib/DWARFLinker/DWARFLinker.cpp:793
+      if (Current.Flags & TF_DependencyWalk)
+        MyInfo.Prune = false;
+      else
----------------
It looks OK. Though add the comment explaining what is going on, please?
That Prune is erased because we decided to keep module forward declaration(and its dependencies) inside lookForRefDIEsToKeep.
