A patch

STV is disabled by

  /* 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;

Please try this.
