--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
No, the assert is certainly desirable there.  TARGET_STV should not have been
enabled in that case, we have:
  /* Disable STV if -mpreferred-stack-boundary={2,3} or
     -mincoming-stack-boundary={2,3} or -mstackrealign - the needed
     stack realignment will be extra cost the pass doesn't take into
     account and the pass can't realign the stack.  */
  if (ix86_preferred_stack_boundary < 128
      || ix86_incoming_stack_boundary < 128
      || opts->x_ix86_force_align_arg_pointer)
    opts->x_target_flags &= ~MASK_STV;
