+/// \brief Check for consistency between a given method declaration and the
+/// methods it overrides within the class hierarchy.
+///
+/// This method walks the inheritance hierarchy starting at the given
+/// declaration context (\p DC), invoking Sema::CheckObjCMethodOverride() with
+/// the given new method (\p NewMethod) and any method it directly overrides
+/// in the hierarchy. Sema::CheckObjCMethodOverride() is responsible for
+/// checking consistency, e.g., among return types for methods that return a
+/// related result type.
