            Bug ID: 60642
           Summary: abi_tag attribute doesn't work on explicit
                    specializations of class templates
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lukeallardyce at gmail dot com

This seems to not be working again in trunk?

template<typename T>
class __attribute((abi_tag("foo"))) test{  };

template class __attribute((abi_tag("foo"))) test<int>;

int main() { }

abi_test.cpp:4:46: error: redeclaration of ‘class test<int>’ adds abi tag "foo"
 template class __attribute((abi_tag("foo"))) test<int>;
