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

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