--- Comment #12 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:7cc5a20ba3f05a783fb75762cfb77ccb571285ab commit r12-8319-g7cc5a20ba3f05a783fb75762cfb77ccb571285ab Author: Iain Sandoe <i...@sandoe.co.uk> Date: Thu Apr 28 20:06:29 2022 +0100 c++, coroutines: Partial reversion of r12-8308-g15a176a833f23e [PR105426]. The changes to fix PR 105287 included a tightening of the constraints on which variables are promoted to frame copies. This has exposed that we are failing to name some variables that should be promoted. We avoid the use of DECL_UID to build anonymous symbols since that might not be stable for -fcompare-debug. The long-term fix is to address the cases where the naming has been missed, but for the short-term (and for the GCC-12 branch) backing out the additional constraint is proposed.
