2019-10-24Revert ABI changes to std::allocator in C++20Jonathan Wakely7-10/+64
The recent C++20 changes to remove the std::allocator<void> explicit specialization and the destructor in the std::allocator primary template change the result of some is_trivially_xxx type traits. To avoid those changes, this patch restores the explicit specialization and the destructor. In order to meet the C++20 requirements the std::allocator<void> explicit specialization must provide the same interface as the primary template (except for the unusable allocate and deallocate member functions) and the destructor in the primary template must be constexpr. * include/bits/allocator.h (allocator<void>): Restore the explicit specialization for C++20, but make its API consistent with the primary template. (allocator::~allocator()): Restore the destructor for C++20, but make it constexpr. * testsuite/20_util/allocator/rebind_c++20.cc: Check allocator<void>. * testsuite/20_util/allocator/requirements/typedefs_c++20.cc: Likewise. * testsuite/20_util/allocator/void.cc: Check that constructors and destructors are trivial.

2019-10-23Adjust pb_ds extensions to use allocator_traitsJonathan Wakely37-469/+382
These changes are largely useless, because most of them are simply allowing 'reference' and 'const_reference' types to be obtained from an allocator, and since C++11 allocators don't define reference types (they just use plain lvalue references. Pretending to support C++98 allocators with user-defined reference types is a waste of time (especially as several of the pb_ds types appear to use a static allocator object which means stateful allocators are not supported). * include/ext/pb_ds/detail/bin_search_tree_/bin_search_tree_.hpp: Use detail::rebind_traits. * include/ext/pb_ds/detail/bin_search_tree_/node_iterators.hpp: Likewise. * include/ext/pb_ds/detail/bin_search_tree_/traits.hpp: Likewise. * include/ext/pb_ds/detail/binary_heap_/binary_heap_.hpp: Likewise. * include/ext/pb_ds/detail/binary_heap_/entry_cmp.hpp: Likewise. * include/ext/pb_ds/detail/binary_heap_/entry_pred.hpp: Likewise. * include/ext/pb_ds/detail/binary_heap_/point_const_iterator.hpp: Likewise. * include/ext/pb_ds/detail/binomial_heap_base_/binomial_heap_base_.hpp: Likewise. * include/ext/pb_ds/detail/branch_policy/branch_policy.hpp: Likewise. * include/ext/pb_ds/detail/cc_hash_table_map_/cc_ht_map_.hpp: Likewise. * include/ext/pb_ds/detail/cond_dealtor.hpp: Likewise. * include/ext/pb_ds/detail/eq_fn/hash_eq_fn.hpp (has_eq_fn): Likewise. * include/ext/pb_ds/detail/gp_hash_table_map_/gp_ht_map_.hpp: Likewise. * include/ext/pb_ds/detail/hash_fn/ranged_hash_fn.hpp: Likewise. * include/ext/pb_ds/detail/hash_fn/ranged_probe_fn.hpp: Likewise. * include/ext/pb_ds/detail/left_child_next_sibling_heap_/ left_child_next_sibling_heap_.hpp: Likewise. * include/ext/pb_ds/detail/left_child_next_sibling_heap_/node.hpp: Likewise. * include/ext/pb_ds/detail/left_child_next_sibling_heap_/ point_const_iterator.hpp: Likewise. * include/ext/pb_ds/detail/list_update_map_/lu_map_.hpp: Likewise. * include/ext/pb_ds/detail/ov_tree_map_/ constructors_destructor_fn_imps.hpp: Likewise. * include/ext/pb_ds/detail/ov_tree_map_/node_iterators.hpp: Likewise. * include/ext/pb_ds/detail/ov_tree_map_/ov_tree_map_.hpp: Likewise. * include/ext/pb_ds/detail/pairing_heap_/pairing_heap_.hpp: Likewise. * include/ext/pb_ds/detail/pat_trie_/pat_trie_.hpp: Likewise. * include/ext/pb_ds/detail/pat_trie_/pat_trie_base.hpp: Likewise. * include/ext/pb_ds/detail/rb_tree_map_/node.hpp: Likewise. * include/ext/pb_ds/detail/rc_binomial_heap_/rc.hpp: Likewise. * include/ext/pb_ds/detail/splay_tree_/node.hpp: Likewise. * include/ext/pb_ds/detail/thin_heap_/thin_heap_.hpp: Likewise. * include/ext/pb_ds/detail/trie_policy/sample_trie_access_traits.hpp: Likewise. * include/ext/pb_ds/detail/type_utils.hpp: Fix typo in comment. * include/ext/pb_ds/detail/types_traits.hpp (stored_value): Add bool parameter to control whether the hash value is stored.
