Implement std::pmr::synchronized_pool_resource 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. This is intended to imply incomplete support, because everything except synchronized_pool_resource works. Implement std::pmr::synchronized_pool_resource * config/abi/pre/gnu.ver: Add new symbols. * include/std/memory_resource [_GLIBCXX_HAS_GTHREADS] (__cpp_lib_memory_resource): Define to expected value, 201603. (synchronized_pool_resource): New class. [!_GLIBCXX_HAS_GTHREADS] (__cpp_lib_memory_resource): Define to 1. * include/std/shared_mutex (__glibcxx_rwlock_rdlock) (__glibcxx_rwlock_tryrdlock, __glibcxx_rwlock_wrlock) (__glibcxx_rwlock_trywrlock, __glibcxx_rwlock_unlock) (__glibcxx_rwlock_destroy, __glibcxx_rwlock_init) (__glibcxx_rwlock_timedrdlock, __glibcxx_rwlock_timedwrlock): Define weak symbols for POSIX rwlock functions. (__shared_mutex_pthread): Use weak symbols. * include/std/version (__cpp_lib_memory_resource): Define. * src/c++17/memory_resource.cc [_GLIBCXX_HAS_GTHREADS] (synchronized_pool_resource::_TPools): New class. (destroy_TPools): New function for pthread_key_create destructor. (synchronized_pool_resource::synchronized_pool_resource) (synchronized_pool_resource::~synchronized_pool_resource) (synchronized_pool_resource::release) (synchronized_pool_resource::do_allocate) (synchronized_pool_resource::do_deallocate): Define public members. (synchronized_pool_resource::_M_thread_specific_pools) (synchronized_pool_resource::_M_alloc_tpools) (synchronized_pool_resource::_M_alloc_shared_tpools): Define private members. * testsuite/20_util/synchronized_pool_resource/allocate.cc: New test. * testsuite/20_util/synchronized_pool_resource/cons.cc: New test. * testsuite/20_util/synchronized_pool_resource/is_equal.cc: New test. * testsuite/20_util/synchronized_pool_resource/multithreaded.cc: New test. * testsuite/20_util/synchronized_pool_resource/release.cc: New test. * testsuite/performance/20_util/memory_resource/pools.cc: Add multithreaded tests using pmr::synchronized_pool_resource.
