--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:a43981bb51fd0b8e68452faea6ec160cbea058e5 commit r9-8879-ga43981bb51fd0b8e68452faea6ec160cbea058e5 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Apr 16 07:19:57 2020 +0200 c++: Fix pasto in structured binding diagnostics [PR94571] This snippet has been copied from the non-structured binding declaration parsing later in the function, and while for non-structured bindings it can be followed by comma or semicolon, structured bindings may be only followed by semicolon. Or, do we want to have a different message for the case when there is a comma (and keep this corrected one only if there is something else) that would explain better what is the bug (or add a fix-it hint)? Marek said in the PR that clang++ reports error: decomposition declaration must be the only declaration in its group There is another thing Marek noted (though, something for different spot), that diagnostic for auto x(1), [e,f] = test2; could also use a clearer wording like the above (or a fix-it hint), but the question is if we should assume [ after , as a structured binding or if we should do some tentative parsing first to figure out if it looks like a structured binding. 2020-04-16 Jakub Jelinek <ja...@redhat.com> PR c++/94571 * parser.c (cp_parser_simple_declaration): Fix up a pasto in diagnostics. * g++.dg/cpp1z/decomp51.C: New test. (cherry picked from commit e4658c7dbbe88f742c96e5f58ee4a6d549d642ca)
