 *  This routine jumps to the directive indicated in the

 *  CPU defined register.  This routine is used when RTEMS is

 *  linked by itself and placed in ROM.  This routine is the

 *  first address in the ROM space for RTEMS.  The user "calls"

 *  this address with the directive arguments in the normal place.

 *  This routine then jumps indirectly to the correct directive

 *  preserving the arguments.  The directive should not realize

 *  it has been "wrapped" in this way.  The table "_Entry_points"

 *  is used to look up the directive.
