--- Comment #6 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:28a164db98d7cb8fa82ac3699471830284502021 commit r9-9394-g28a164db98d7cb8fa82ac3699471830284502021 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Nov 24 09:04:28 2020 +0100 openmp: Fix C ICE on OpenMP atomics c_parser_binary_expression was using build2 to create a temporary holder for binary expression that c_parser_atomic and c_finish_omp_atomic can then handle. The latter performs then all the needed checking. Unfortunately, build2 performs some checking too, e.g. PLUS_EXPR vs. POINTER_PLUS_EXPR or matching types of the arguments, nothing we can guarantee at the parsing time. So we need something like C++ build_min_nt*. This patch implements that inline. 2020-11-24 Jakub Jelinek <ja...@redhat.com> PR c/97958 * c-parser.c (c_parser_binary_expression): For omp atomic binary expressions, use make_node instead of build2 to avoid checking build2 performs. * c-c++-common/gomp/pr97958.c: New test.
