From: Tobias Burnus <burnus@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc/devel/omp/gcc-12] openmp: Be consistent on parsing offsets between normal sink vector and omp_cur_iteration - 1 Date: Wed, 7 Sep 2022 11:01:56 +0000 (GMT) [thread overview] Message-ID: <20220907110156.269463850841@sourceware.org> (raw) https://gcc.gnu.org/g:943cc3e7ed020a2a841419bba1516cf47c7e2e81 commit 943cc3e7ed020a2a841419bba1516cf47c7e2e81 Author: Jakub Jelinek <jakub@redhat.com> Date: Tue Sep 6 10:19:45 2022 +0200 openmp: Be consistent on parsing offsets between normal sink vector and omp_cur_iteration - 1 For normal sink vectors, we just check that the token is CPP_NUMBER and with INTEGER_CST value, while for omp_cur_iteration I was additionally requiring integer_type_node type (so only 1, 001, 0x0001 but not 1L or 1ULL etc.). I think we need to clarify what we actually should allow in the standard, until then it is better to be consistent. 2022-09-06 Jakub Jelinek <jakub@redhat.com> gcc/c/ * c-parser.cc (c_parser_omp_clause_doacross_sink): Don't verify val in omp_cur_iteration - 1 has integer_type_node type. gcc/cp/ * parser.cc (cp_parser_omp_clause_doacross_sink): Don't verify val in omp_cur_iteration - 1 has integer_type_node type. gcc/testsuite/ * c-c++-common/gomp/doacross-6.c (corge): Don't expect an error here. Add a few further tests.
