--- Comment #14 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:c4212c41daa8584c0e63862a709d03da0c7f3dee commit r12-9811-gc4212c41daa8584c0e63862a709d03da0c7f3dee Author: Jason Merrill <ja...@redhat.com> Date: Mon May 1 10:57:20 2023 -0400 c++: array DMI and member fn [PR109666] Here it turns out I also needed to adjust cfun when stepping out of the member function to instantiate the DMI. But instead of adding that tweak, let's unify with instantiate_body and just push_to_top_level instead of trying to do the minimum subset of it. There was no measurable change in compile time on stdc++.h. This should also resolve 109506 without yet another tweak.
