--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:8d344146727da02eb5c62fbf6cee97a4e96d63db commit r14-2535-g8d344146727da02eb5c62fbf6cee97a4e96d63db Author: Jason Merrill <ja...@redhat.com> Date: Fri Jul 14 09:37:21 2023 -0400 c++: c++26 regression fixes Apparently I wasn't actually running the testsuite in C++26 mode like I thought I was, so there were some failures I wasn't seeing. The constexpr hunk fixes regressions with the P2738 implementation; we still need to use the old handling for casting from void pointers to heap variables. PR c++/110344 gcc/cp/ChangeLog: * constexpr.cc (cxx_eval_constant_expression): Move P2738 handling after heap handling. * name-lookup.cc (get_cxx_dialect_name): Add C++26. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/constexpr-cast2.C: Adjust for P2738. * g++.dg/ipa/devirt-45.C: Handle -fimplicit-constexpr.
