--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:3a93c67f21818eafd6823a7c3d06db1432f9c07b commit r11-8787-g3a93c67f21818eafd6823a7c3d06db1432f9c07b Author: Iain Sandoe <i...@sandoe.co.uk> Date: Thu Jul 8 09:42:49 2021 +0100 coroutines: Adjust outlined function names [PR95520]. The mechanism used to date for uniquing the coroutine helper functions (actor, destroy) was over-complicating things and leading to the noted PR and also difficulties in setting breakpoints on these functions (so this will help PR99215 as well). This implementation delegates the adjustment to the mangling to write_encoding() which necessitates some book-keeping so that it is possible to determine which of the coroutine helper names is to be mangled. Signed-off-by: Iain Sandoe <i...@sandoe.co.uk> PR c++/95520 - [coroutines] __builtin_FUNCTION() returns mangled .actor instead of original function name PR c++/95520 gcc/cp/ChangeLog: * coroutines.cc (struct coroutine_info): Add fields for actor and destroy function decls. (to_ramp): New. (coro_get_ramp_function): New. (coro_get_actor_function): New. (coro_get_destroy_function): New. (act_des_fn): Set up mapping between ramp, actor and destroy functions. (morph_fn_to_coro): Adjust interface to the builder for helper function decls. * cp-tree.h (DECL_ACTOR_FN, DECL_DESTROY_FN, DECL_RAMP_FN, JOIN_STR): New. * mangle.c (write_encoding): Handle coroutine helpers. (write_unqualified_name): Handle lambda coroutine helpers. gcc/testsuite/ChangeLog: * g++.dg/coroutines/pr95520.C: New test. (cherry picked from commit 237ab3ee49e2f3110accfcc03b6c0df8b4889f15)
