From: Jonathan Wakely Date: Wed, 23 Oct 2019 16:14:28 +0000 (+0100) Subject: Adjust extension types to use allocator_traits X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=603aec6775d5191fafd57412364578db68432f74;p=gcc.git Adjust extension types to use allocator_traits This makes these extensions work with types meeting the Cpp17Allocator requirements as well as the C++98 Allocator requirements. * include/backward/hash_set (hash_set): Use __alloc_traits. * include/backward/hashtable.h (_Hashtable): Likewise. * include/ext/alloc_traits.h (__alloc_traits::allocate): Add overload taking a hint. * include/ext/extptr_allocator.h (_ExtPtr_allocator::allocate): Ignore hint. * include/ext/slist (_Slist_base): Use __alloc_traits. * include/tr1/hashtable.h (_Hashtable): Likewise. * include/tr1/regex (match_results): Use vector::const_reference instead of assuming the allocator defines it. * testsuite/backward/hash_map/23528.cc: Use allocator_traits in C++11. * testsuite/tr1/6_containers/unordered_map/capacity/29134-map.cc: Use __gnu_test::max_size. * testsuite/tr1/6_containers/unordered_multimap/capacity/ 29134-multimap.cc: Likewise. * testsuite/tr1/6_containers/unordered_multiset/capacity/ 29134-multiset.cc: Likewise. * testsuite/tr1/6_containers/unordered_set/capacity/29134-set.cc: Likewise.
