;***********************************************************************
;*
;* Name: rdr_shift_out_U
;*
;* Description:
;* This routine moves data to the RDR's. The double-word that
;* arg1 points to is loaded and moved into the staging register.
;* Then the STDIAG instruction for the RDR # in arg0 is called
;* to move the data to the RDR.
;*
;* Arguments:
;* arg0 = rdr target
;* arg1 = buffer pointer
;*
;* Returns:
;* None
;*
;* Register usage:
;* arg0 = rdr target
;* arg1 = buffer pointer
;* %r24 - DR2 | DR2_SLOW_RET
;* %r23 - original DR2 value
;*
