get_address_description only does that if TMR_INDEX2 is present:
      addr->symbol = NULL_TREE;
      if (TMR_INDEX2 (op))
        {
          gcc_assert (integer_zerop (TMR_BASE (op)));
          addr->base = TMR_INDEX2 (op);
        }
      else
        addr->base = TMR_BASE (op);

In this case TMR_BASE (op) is (void *) 0 and TMR_OFFSET is INTEGER_CST, the
rest is all NULL.
