rsmith added inline comments.

Comment at: include/clang/AST/DeclBase.h:2055-2075
+template<>
+struct GraphTraits<const ::clang::DeclContext *> {
+ using NodeRef = const ::clang::Decl *;
+ using ChildIteratorType = ::clang::DeclContext::decl_iterator;
+
+ static NodeRef getEntryNode(const ::clang::DeclContext *DC) {
+ return cast<::clang::Decl>(DC);
----------------
Neat :)
================
Comment at: lib/Sema/SemaDecl.cpp:16354
+ if (auto *DC = dyn_cast<DeclContext>(*It))
+ VisitChildren = DC->isLookupContext();
+
----------------
This will prematurely stop traversal if we reach a `LinkageSpecDecl`. I think
we should instead stop if we reach a declaration for which
`!DC->getRedeclContext()->isFileContext()` (that is, we should check
namespace-scope declarations only).
