--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
static void
arm_print_operand (FILE *stream, rtx x, int code)
{
  switch (code)
    {
...
    case 'I':
      fprintf (stream, "%s", arithmetic_instr (x, 0));
      return;


...
const char *
arithmetic_instr (rtx op, int shift_first_arg)
{
  switch (GET_CODE (op))
    {
...
    default:
      gcc_unreachable ();
    }
}

The gcc_unreachable here should rather be a call to output_operand_lossage=
