--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:7083aeaef5b6d8be1ae419b834e8e56d90026ace commit r16-2367-g7083aeaef5b6d8be1ae419b834e8e56d90026ace Author: Jakub Jelinek <ja...@redhat.com> Date: Sun Jul 20 08:12:57 2025 +0200 libstdc++: Export std::dextents from std.cc.in [PR121174] r16-442 implemented both std::extents and std::dextents (and perhaps other stuff), but exported only std::extents. I went through https://eel.is/c++draft/mdspan.syn and I think std::dextents is the only one implemented but not exported. The following patch exports it, and additionally appends some further entities to the FIXME list, those all seems to be unimplemented yet. 2025-07-20 Jakub Jelinek <ja...@redhat.com> PR libstdc++/121174 * src/c++23/std.cc.in (std::dextents): Export. Add to FIXME comments other not yet implemented nor exported <mdspan> entities.
