             Bug #: 13325
           Summary: #pragma visibility processed at point of instantiation
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: ASSIGNED
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: rafael.espindola at gmail.com
        ReportedBy: rafael.espindola at gmail.com

We produce a hidden reference to _M_fill_insert in

template<typename _Tp > struct vector   {
  static void       _M_fill_insert();
};
#pragma GCC visibility push(hidden)
void foo() {
  vector<unsigned>::_M_fill_insert();
}

This happens because AddPushedVisibilityAttribute is called during template
instantiatition, where the pragma is already active.
