_Local_iterator_base inherits _Node_iterator_base and so share the same comparison operators. It avoids to expose special method _M_curr for debug mode to compare such iterators. libstdc++-v3/ChangeLog: * include/bits/hashtable_policy.h (_Node_iterator_base()): New. (operator==(const _Node_iterator_base&, const _Node_iterator_base&)): Make hidden friend. (operator!=(const _Node_iterator_base&, const _Node_iterator_base&)): Make hidden friend. (_Local_iterator_base<>): Inherits _Node_iterator_base. (_Local_iterator_base<>::_M_cur): Remove. (_Local_iterator_base<>::_M_curr()): Remove. (operator==(const _Local_iterator_base&, const _Local_iterator_base&)): Remove. (operator!=(const _Local_iterator_base&, const _Local_iterator_base&)): Remove. * include/debug/unordered_map (unordered_map<>::_M_invalidate): Adapt. (unordered_multimap<>::_M_invalidate): Adapt. * include/debug/unordered_set (unordered_set<>::_M_invalidate): Adapt. (unordered_multiset<>::_M_invalidate): Adapt.
