/* set_vector
*
* This routine installs an interrupt vector on the HP PA-RISC simulator.
*
* INPUT:
* handler - interrupt handler entry point
* vector - vector number
* type - 0 indicates raw hardware connect
* 1 indicates RTEMS interrupt connect
*
* NOTE 'type' is ignored on hppa; all interrupts are owned by RTEMS
*
* RETURNS:
* address of previous interrupt handler
