--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Yes, that is new in OpenMP 5.0, 4.5 didn't have it. Usually we do this in the gimplifier (gimplify_scan_omp_clauses), we also know there whether it is a combined construct or not. Look for the various spots where we omp_notice_variable in the outer context there based on various conditions.
