--- Comment #2 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:cdffc76393488a73671b70481cf8a4b7c289029d commit r15-7692-gcdffc76393488a73671b70481cf8a4b7c289029d Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Feb 25 09:33:21 2025 +0100 openmp: Mark OpenMP atomic write expression as read [PR119000] The following testcase was emitting false positive warning that the rhs of #pragma omp atomic write was stored but not read, when the atomic actually does read it. The following patch fixes that by calling default_function_array_read_conversion on it, so that it is marked as read as well as converted from lvalue to rvalue. Furthermore, the code had if (code == NOP_EXPR) ... else ... if (code == NOP_EXPR) ... with none of ... parts changing code, so I've merged the two ifs. 2025-02-25 Jakub Jelinek <ja...@redhat.com> PR c/119000 * c-parser.cc (c_parser_omp_atomic): For omp write call default_function_array_read_conversion on the rhs expression. Merge the two adjacent if (code == NOP_EXPR) blocks. * c-c++-common/gomp/pr119000.c: New test.
