Table C-22 shows the simplified branch mnemonics and syntax for bclrl and bcctrl with LR
updating.

1
The value in the BI operand selects CR n [0], the LT bit.
2
The value in the BI operand selects CR n [1], the GT bit.
3
The value in the BI operand selects CR n [2], the EQ bit.
4
The value in the BI operand selects CR n [3], the SO bit.
