Prefer to overload __to_address to partially specialize std::pointer_traits because std::pointer_traits would be mostly useless. Moreover partial specialization of pointer_traits<__normal_iterator<P, C>> fails to rebind C, so you get incorrect types like __normal_iterator<long*, vector<int>>. In the case of __gnu_debug::_Safe_iterator the to_pointer method is impossible to implement correctly because we are missing the parent container to associate the iterator to. libstdc++-v3/ChangeLog: * include/bits/stl_iterator.h (std::pointer_traits<__gnu_cxx::__normal_iterator<>>): Remove. (std::__to_address(const __gnu_cxx::__normal_iterator<>&)): New for C++11 to C++17. * include/debug/safe_iterator.h (std::__to_address(const __gnu_debug::_Safe_iterator<__gnu_cxx::__normal_iterator<>, _Sequence>&)): New for C++11 to C++17. * testsuite/24_iterators/normal_iterator/to_address.cc: Add check on std::vector::iterator to validate both __gnu_cxx::__normal_iterator<> __to_address overload in normal mode and __gnu_debug::_Safe_iterator in _GLIBCXX_DEBUG mode. |
