--- Comment #3 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:53d8ed13bb5a6972efab7c56c066010cd1f78b35 commit r15-8267-g53d8ed13bb5a6972efab7c56c066010cd1f78b35 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Mar 18 18:51:48 2025 +0100 c: Fix handling of [[gnu::musttail] return in if and else bodies [PR119311] The following new testcase FAILs with C (and succeeds with C++). c_parser_handle_musttail is used in c_parser_compound_statement_nostart where it is directly passed to c_parser_statement_after_labels, and in c_parser_all_labels where it is returned. Now, out of the 3 c_parser_all_labels callers, c_parser_statement passes it down to c_parser_statement_after_labels, but c_parser_if_body and c_parser_else_body don't, so if there are return statements with [[gnu::musttail]] or [[clang::musttail]] directly in if or else bodies rather than wrapped with {}s, we throw that information away. 2025-03-18 Jakub Jelinek <ja...@redhat.com> PR c/119311 * c-parser.cc (c_parser_if_body): Pass result of c_parser_all_labels as last argument to c_parser_statement_after_labels. (c_parser_else_body): Likewise. * c-c++-common/musttail14.c: Use * instead of \* in the regexps. * c-c++-common/musttail25.c: New test.
