|
;* Name: perf_rdr_shift_in_W
|
|
;*
|
|
;* Description:
|
|
;* This routine shifts data in from the RDR in arg0 and returns
|
|
;* the result in ret0. If the RDR is <= 64 bits in length, it
|
|
;* is shifted shifted backup immediately. This is to compensate
|
|
;* for RDR10 which has bits that preclude PDC stack operations
|
|
;* when they are in the wrong state.
|
|
;*
|
|
;* Arguments:
|
|
;* arg0 : rdr to be read
|
|
;* arg1 : bit length of rdr
|
|
;*
|
|
;* Returns:
|
|
;* ret0 = next 64 bits of rdr data from staging register
|
|
;*
|
|
;* Register usage:
|
|
;* arg0 : rdr to be read
|
|
;* arg1 : bit length of rdr
|
|
;* %r24 - original DR2 value
|
|
;* %r1 - scratch
|
|
;* %r29 - scratch
|
|
;*
|
|
;* Returns:

|
|
;* Name: rdr_shift_in_U
|
|
;*
|
|
;* Description:
|
|
;* This routine shifts data in from the RDR in arg0 and returns
|
|
;* the result in ret0. If the RDR is <= 64 bits in length, it
|
|
;* is shifted shifted backup immediately. This is to compensate
|
|
;* for RDR10 which has bits that preclude PDC stack operations
|
|
;* when they are in the wrong state.
|
|
;*
|
|
;* Arguments:
|
|
;* arg0 : rdr to be read
|
|
;* arg1 : bit length of rdr
|
|
;*
|
|
;* Returns:
|
|
;* ret0 = next 64 bits of rdr data from staging register
|
|
;*
|
|
;* Register usage:
|
|
;* arg0 : rdr to be read
|
|
;* arg1 : bit length of rdr
|
|
;* %r24 - original DR2 value
|
|
;* %r23 - DR2 | DR2_SLOW_RET
|
|
;* %r1 - scratch

;* 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
