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