--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Confirmed. expand_omp_simd has for this case:
6837 /* If not -fno-tree-loop-vectorize, hint that we want to vectorize
6838 the loop. */
6839 if ((flag_tree_loop_vectorize
6840 || (!global_options_set.x_flag_tree_loop_vectorize
6841 && !global_options_set.x_flag_tree_vectorize))
6842 && loop->safelen > 1)
6843 {
6844 loop->force_vect = true;
6845 cfun->has_force_vect_loops = true;
6846 }
but gate_tree_loop_vectorize isn't called at all, because gate_tree_loop
returns false. So maybe:

No, instead we should treat !flag_tree_loop_optimize the same as we treat
explicit -fno-tree-vectorize in omp-low.c (there are two spots).
