Simplified mnemonics for branch instructions that do not test a CR bit should not specify one; a programming error may
occur.
The value in the BI operand selects CRn[2], the EQ bit.
Instructions for which B0 is either 12 (branch if condition true) or 4 (branch if condition false) do not depend on the CTR
value and can be alternately coded by incorporating the condition specified by the BI field, as described in Section 4.6,
“Simplified Mnemonics that Incorporate CR Conditions (Eliminates BO and Replaces BI with crS).”
The value in the BI operand selects CRn[0], the LT bit.
The value in the BI operand selects CRn[1], the GT bit.
The value in the BI operand selects CRn[3], the SO bit.
