--- Comment #2 from CVS 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:04b2fb5bb644f172879a02e8374ad50b669e3d6d commit r14-4167-g04b2fb5bb644f172879a02e8374ad50b669e3d6d Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Sep 20 08:43:02 2023 +0200 openmp: Add omp::decl attribute support [PR111392] This patch adds support for (so far C++) omp::decl attribute. For declare simd and declare variant directives it is essentially another spelling of omp::decl, except per discussions it is not allowed inside of omp::sequence attribute. For threadprivate, declare target, allocate and later groupprivate directives it should appertain to variable (or for declare target also function definitions and) declarations and where in normal syntax one specifies a list of variables (or variables and functions), either as argument of the directive or clause argument, such argument is not specified and implied to be the variable it applies to. 2023-09-20 Jakub Jelinek <ja...@redhat.com> PR c++/111392 gcc/ * attribs.cc (decl_attributes): Don't warn on omp::directive attribute on vars or function decls if -fopenmp or -fopenmp-simd. gcc/c-family/ * c-omp.cc (c_omp_directives): Add commented out groupprivate directive entry. gcc/cp/ * parser.h (struct cp_lexer): Add in_omp_decl_attribute member. * cp-tree.h (cp_maybe_parse_omp_decl): Declare. * parser.cc (cp_parser_handle_statement_omp_attributes): Diagnose omp::decl attribute on statements.
