  /* For vector typed comparisons emit code to generate the desired
     all-ones or all-zeros mask.  */
  if (VECTOR_TYPE_P (ops->type))
    {
      tree ifexp = build2 (ops->code, ops->type, arg0, arg1);
      if (VECTOR_BOOLEAN_TYPE_P (ops->type)
          && expand_vec_cmp_expr_p (TREE_TYPE (arg0), ops->type, ops->code))
        return expand_vec_cmp_expr (ops->type, ifexp, target);
      else
        gcc_unreachable ();

that means we end up with a non-boolean vector "flag".  Possibly a middle-end
issue indeed.
