--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:94fd05f1f76faca9dc9033b55d44c960155d38e9 commit r11-4120-g94fd05f1f76faca9dc9033b55d44c960155d38e9 Author: Jonathan Wakely <jwak...@redhat.com> Date: Tue Oct 20 11:19:58 2020 +0100 libstdc++: Define noop coroutine details private and inline [PR 95917] This moves the __noop_coro_frame type, the __noop_coro_fr global variable, and the __dummy_resume_destroy function from namespace scope, replacing them with private members of the specialization coroutine_handle<noop_coroutine_promise>. The function and variable are also declared inline, so that they generate no code unless used. libstdc++-v3/ChangeLog: PR libstdc++/95917 * include/std/coroutine (__noop_coro_frame): Replace with noop_coroutine_handle::__frame. (__dummy_resume_destroy): Define inline in __frame. (__noop_coro_fr): Replace with noop_coroutine_handle::_S_fr and define as inline. * testsuite/18_support/coroutines/95917.cc: New test.
