[PATCH] D32759: Fix errored return value in CheckFunctionReturnType and add a fixit hint

[Eli Friedman via Phabricator via cfe-commits]

efriedma added a comment.

The difference between returning true and false here is just the way error 
recovery works: when we return true, we know the type is invalid, so we 
suppress it, and subsequent errors involving the declaration.  Example 
(Objective-C++) where we currently print two errors:

  @class NSObject;
  template<typename T> struct C {
      static T f();
  };
  int g() { NSObject *x = C<NSObject>::f(); }
