 368              sign-extended to 64 bits and the address of
 369              the branch instruction. For B-form branches
 370              the effective address of the branch target is
 371              the sum of the BD field sign-extended to 64
 372              bits and the address of the branch instruction.

 374              address. For I-form branches the effective
 375              address of the branch target is the LI field
 376              sign-extended to 64 bits. For B-form branches
 377              the effective address of the branch target is
 378              the BD field sign-extended to 64 bits.
