0b201f8aac3787e0037d82a4c298f9c91db8c3f6 Mon Sep 17 00:00:00 2001 From: Zsolt Parragi Date: Sun, 19 Jul 2020 21:41:41 +0200 Subject: [PATCH 2/5] Support both and Starting with GCC 10.1, GCC/libstdc++ supports coroutines, but includes them in their final location in . This commit generalizes the location of the header, and the name of the types (either in the std or std::experimental namespace), so that both the current Clang/MSVC and the GCC approach can be supported. This should also guarantee that both current and later Clang/MSVC releases will be supported by the library. --- include/cppcoro/async_auto_reset_event.hpp | 6 +-- include/cppcoro/async_generator.hpp | 52 +++++++++---------- include/cppcoro/async_manual_reset_event.hpp | 6 +-- include/cppcoro/async_mutex.hpp | 6 +-- include/cppcoro/async_scope.hpp | 10 ++-- include/cppcoro/coroutine.hpp | 32 ++++++++++++ include/cppcoro/detail/is_awaiter.hpp | 8 +-- include/cppcoro/detail/sync_wait_task.hpp | 14 ++--- include/cppcoro/detail/when_all_counter.hpp | 6 +-- .../detail/when_all_ready_awaitable.hpp | 16 +++--- include/cppcoro/detail/when_all_task.hpp | 12 ++--- .../detail/win32_overlapped_operation.hpp | 10 ++-- include/cppcoro/file.hpp | 2 +- include/cppcoro/file_read_operation.hpp | 2 +- include/cppcoro/file_write_operation.hpp | 2 +- include/cppcoro/fmap.hpp | 2 +- include/cppcoro/generator.hpp | 20 +++---- include/cppcoro/inline_scheduler.hpp | 4 +- include/cppcoro/io_service.hpp | 8 +-- include/cppcoro/multi_producer_sequencer.hpp | 8 +-- include/cppcoro/read_only_file.hpp | 2 +- include/cppcoro/read_write_file.hpp | 2 +- include/cppcoro/recursive_generator.hpp | 20 +++---- include/cppcoro/round_robin_scheduler.hpp | 16 +++--- include/cppcoro/sequence_barrier.hpp | 6 +-- include/cppcoro/shared_task.hpp | 26 +++++----- ...single_consumer_async_auto_reset_event.hpp | 8 +-- include/cppcoro/single_consumer_event.hpp | 6 +-- include/cppcoro/single_producer_sequencer.hpp | 4 +- include/cppcoro/static_thread_pool.hpp | 6 +-- include/cppcoro/task.hpp | 36 ++++++------- include/cppcoro/write_only_file.hpp | 2 +- lib/async_auto_reset_event.cpp | 2 +- lib/async_manual_reset_event.cpp | 2 +- lib/async_mutex.cpp | 2 +- lib/file.cpp | 2 +- lib/io_service.cpp | 6 +-- lib/read_only_file.cpp | 2 +- lib/read_write_file.cpp | 2 +- lib/static_thread_pool.cpp | 2 +- lib/write_only_file.cpp | 2 +- test/file_tests.cpp | 6 +-- test/static_thread_pool_tests.cpp | 6 +-- 43 files changed, 213 insertions(+), 181 deletions(-) create mode 100644 include/cppcoro/coroutine.hpp diff --git a/include/cppcoro/async_auto_reset_event.hpp b/include/cppcoro/async_auto_reset_event.hpp index ce1f2d80..b74ae2b5 100644 --- a/include/cppcoro/async_auto_reset_event.hpp +++ b/include/cppcoro/async_auto_reset_event.hpp @@ -5,7 +5,7 @@ #ifndef CPPCORO_ASYNC_AUTO_RESET_EVENT_HPP_INCLUDED #define CPPCORO_ASYNC_AUTO_RESET_EVENT_HPP_INCLUDED -#include +#include #include #include @@ -80,7 +80,7 @@ namespace cppcoro async_auto_reset_event_operation(const async_auto_reset_event_operation& other) noexcept;
