--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Comment on attachment 42476 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42476 Updated tentative patch Both TEAMS and SINGLE don't have any inlines that actually need gomp_teams or gomp_single, they accept just gimple. So for those please just avoid the {}s and as_a, just do: case GIMPLE_OMP_SINGLE: t = unshare_expr (gimple_omp_single_clauses (stmt)); gimple_omp_single_set_clauses (copy, t); goto copy_omp_body; etc. For TARGET it is indeed needed for target_set_data_arg, so keep that one as is. Preapproved with that change.
