This revision is now accepted and ready to land.
This is fairly visible, but seems reasonably safe to me. Let's see if anyone complains :-)
================
Comment at: clang/test/Parser/cxx-keyword-identifiers.cpp:16
+int foo5(int x const); // expected-error {{expected ')'}} expected-note {{to match this '('}}
+int foo6(int case __attribute((weak))); // expected-error {{invalid parameter}} \
+ // expected-error {{expected ')'}} expected-note {{to match this '('}}
----------------
can you add a comment like FIXME: bad recovery?
(So future readers/modifiers can know which tests are establishing desirable behavior vs documenting current accidental behavior)
Actually I think this is better than the old behaviour (but ideally we'd suppress the followon diagnostic)
