The problem here is that target cleanup expressions have been added to the initialisers for the awaitable (and returns of non-trivial values from await_suspend() calls. This is because the expansion of the co_await into its control flow is not apparent to the machinery adding the target cleanup expressions. The solution being tested is simply to recreate target expressions as the co_awaits are lowered. Teaching the machinery to handle walking co_await expressions in different ways at different points (outside the coroutine transformation) seems overly complex. gcc/cp/ChangeLog: 2020-04-30 Iain Sandoe <iain@sandoe.co.uk> PR c++/94883 * coroutines.cc (register_awaits): Update target expressions for awaitable and suspend handle initializers. gcc/testsuite/ChangeLog: 2020-04-30 Iain Sandoe <iain@sandoe.co.uk> PR c++/94883 * g++.dg/coroutines/pr94883-folly-2.C: 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.
