GCC modified for the FreeChainXenon project

As was previously done for std::thread, this removes an unnecessary copy of an rvalue of type thread::_Invoker. Instead of creating the rvalue and then moving that into the shared state, the member of the shared state is initialized directly from the forwarded callable and bound arguments. This also slightly simplifies std::thread creation to remove the _S_make_state helper function. libstdc++-v3/ChangeLog: PR libstdc++/69724 * include/std/future (__future_base::_S_make_deferred_state) (__future_base::_S_make_async_state): Remove. (__future_base::_Deferred_state): Change constructor to accept a parameter pack of arguments and forward them to the call wrapper. (__future_base::_Async_state_impl): Likewise. Replace lambda expression with a named member function. (async): Construct state object directly from the arguments, instead of using thread::__make_invoker, _S_make_deferred_state and _S_make_async_state. Move shared state into the returned future. * include/std/thread (thread::_Call_wrapper): New alias template for use by constructor and std::async. (thread::thread(Callable&&, Args&&...)): Create state object directly instead of using _S_make_state. (thread::__make_invoker, thread::__decayed_tuple) (thread::_S_make_state): Remove. * testsuite/30_threads/async/69724.cc: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
