| ;* 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) |

| ;* 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 |
