--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:23d16b36eb41366841af052c35f335f35ee203cc commit r11-10699-g23d16b36eb41366841af052c35f335f35ee203cc Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Jan 19 21:00:08 2023 +0100 openmp: Fix up OpenMP expansion of non-rectangular loops [PR108459] expand_omp_for_init_counts was using for the case where collapse(2) inner loop has init expression dependent on non-constant multiple of the outer iterator and the condition upper bound expression doesn't depend on the outer iterator fold_unary (NEGATE_EXPR, ...). This will just return NULL if it can't be folded, we need fold_build1 instead. 2023-01-19 Jakub Jelinek <ja...@redhat.com> PR middle-end/108459 * omp-expand.c (expand_omp_for_init_counts): Use fold_build1 rather than fold_unary for NEGATE_EXPR. * testsuite/libgomp.c/pr108459.c: New test.
