  24    This state is maintained in host byte order.  The
  25    fetch/store register functions must translate between host
  26    byte order and the target processor byte order.
  27    Keeping this data in target byte order simplifies the register
  28    read/write functions.  Keeping this data in native order improves
  29    the performance of the simulator.  Simulation speed is deemed more
