We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

;*
;* 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:
;* ret0 = RDR data (right justified)

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

;*
;* 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
