- B-form branches the effective address of
- the branch target is the sum of the BD
- field sign-extended to 64 bits and the
- address of the branch instruction.
- 1 The immediate field represents an abso-
- lute address. For I-form branches the
- effective address of the branch target is
- the LI field sign-extended to 64 bits. For
- B-form branches the effective address of
- the branch target is the BD field
- sign-extended to 64 bits.

- a Branch Conditional instruction.
-BO (6:10)
- Field used to specify options for the Branch Condi-
- tional instructions. The encoding is described in
- Section 2.5, 'Branch Instructions'.
-BT (6:10)
- Field used to specify a bit in the CR or in the
- FPSCR to be used as a target.
-BX (30) & B(16:20)
- Fields that are concatenated to specify a VSR to
- be used as a source.

- Register instructions (see Book III-E).
-DGM (16:21)
- Immediate field used as the Data Group Mask.
-DM (24:25)
- Immediate field used by xxpermdi instruction as
- doubleword permute control.
-DQ (16:27)
- Immediate field used to specify a 12-bit signed
- two's complement integer which is concatenated
- on the right with 0b0000 and sign-extended to 64
- bits.
-DS (16:29)
- Immediate field used to specify a 14-bit signed
- two's complement integer which is concatenated
- on the right with 0b00 and sign-extended to 64
- bits.
