Commit Message

Eric Blake May 14, 2015, 12:50 p.m. UTC 
Enhance the testsuite to cover a downstream enum type and enum
string.  Update the generator to mangle the enum name in the
appropriate places.

Signed-off-by: Eric Blake <eblake@redhat.com>

---

v4: use type_name() instead of special-casing builtins in
generate_visit_list()
