The _Tuple_impl base class can be used to disable copy/move assignment, without requiring an extra base class. Exception specifications on std::tuple assignment and swap functions can be defined directly using is_nothrow_swappable, instead of querying the base classes. PR libstdc++/86963 * include/std/tuple (_Tuple_impl::operator=): Define as deleted. (_Tuple_impl::_M_assign): New functions to perform assignment instead of assignment operators. (_Tuple_impl::_M_swap): Remove exception specification. (_Tuple_impl<_Idx, _Head>): Likewise. (_TC::_NonNestedTuple, _TC::_NotSameTuple): Use __remove_cvref_t. (__tuple_base): Remove. (tuple, tuple<_T1, _T2>): Remove inheritance from __tuple_base. (tuple::operator=, tuple<_T1, _T2>::operator=): Call _M_assign. (tuple::swap, tuple<_T1, _T2>::swap): Define exception specification using __is_nothrow_swappable. (tuple<_T1, _T2>::tuple(_U1&&, _U2&&)): Use __remove_cvref_t. From-SVN: r263661 |
