2019-01-04Export explicit instantiations for C++17 members of std::stringJonathan Wakely1-1/+23
The C++17 standard added some new members to std::basic_string, which were not previously instantiated in the library. This meant that the extern template declarations had to be disabled for C++17 mode. With this patch the new members are instantiated in the library and so the explicit instantiation declarations can be used for C++17. The new members added by C++2a are still not exported, and so the explicit instantiation declarations are still disabled for C++2a. * config/abi/pre/gnu.ver (GLIBCXX_3.4.21): Make patterns less greedy for const member functions of std::basic_string. (GLIBCXX_3.4.26): Export member functions of std::basic_string added in C++17. * include/bits/basic_string.h (basic_string(__sv_wrapper, const A&)): Make non-standard constructor private. [!_GLIBCXX_USE_CXX11_ABI] (basic_string(__sv_wrapper, const A&)): Likewise. * include/bits/basic_string.tcc (std::string, std::wstring): Declare explicit instantiations for C++17 as well as earlier dialects. * src/c++17/Makefile.am: Add new source files. * src/c++17/Makefile.in: Regenerate. * src/c++17/cow-string-inst.cc: New file defining explicit instantiations for basic_string member functions added in C++17. * src/c++17/string-inst.cc: Likewise.

2019-01-04Add allocator-extended copy/move ctors to COW stringJonathan Wakely1-0/+5
Add these constructors from C++11 which were missing from the COW basic_string. Additionally simplify the definitions of the basic_string::reference and basic_string::const_reference types as required by C++11. This allows filesystem::path::string<Allocator>() to be simplified, so that the same code is used for both basic_string implementations. * config/abi/pre/gnu.ver (GLIBCXX_3.4.26): Export allocator-extended copy/move constructors for old std::basic_string. * include/bits/basic_string.h [!_GLIBCXX_USE_CXX11_ABI] (basic_string::reference, basic_string::const_reference): Define as plain references for C++11 and later.

2018-11-17Implement std::pmr::synchronized_pool_resourceJonathan Wakely1-7/+12
Define the thread-safe pool resource, using a shared_mutex to allow multiple threads to concurrently allocate from thread-specific pools. Define new weak symbols for the pthread_rwlock_t functions, to avoid making libstdc++.so depend on libpthread.so When the necessary Gthread support is absent only define the feature-test macro to 1, rather than 201603.

2018-07-24Add initial version of C++17 <memory_resource> headerJonathan Wakely1-0/+5
This is missing the synchronized_pool_resource and unsynchronized_pool_resource classes but is otherwise complete. This is a new implementation, not based on the existing code in <experimental/memory_resource>, but memory_resource and polymorphic_allocator ended up looking almost the same anyway. The constant_init kluge in src/c++17/memory_resource.cc is apparently due to Richard Smith and ensures that the objects are constructed during constant initialiation phase and not destroyed (because the constant_init destructor doesn't destroy the union member and the storage is not reused). * config/abi/pre/gnu.ver: Export new symbols. * configure: Regenerate. * include/Makefile.am: Add new <memory_resource> header. * include/Makefile.in: Regenerate. * include/precompiled/stdc++.h: Include <memory_resource> for C++17. * include/std/memory_resource: New header.

2018-06-21PR libstdc++/83328 add correct basic_string::insert for initializer_listJonathan Wakely1-1/+35
The SSO basic_string has a non-standard insert(iterator, initializer_list) overload, from a C++0x draft. This adds the correct overload, while also preserving the old one so that the old symbol is still exported from the library. The COW basic_string doesn't have any of the C++11 changes to the insert overloads (they all still have non-const iterator parameters and the ones that should return an iterator still return void). This doesn't make any change to the COW string.
