356 # 1.6.28 Instruction Fields
357 A (6)
358 Field used by the tbegin. instruction to specify an
359 implementation-specific function.
360 Field used by the tend. instruction to specify the
361 completion of the outer transaction and all nested
362 transactions.
363 Formats: X
364 AA (30)
365 Absolute Address.
366 0 The immediate field represents an address
367 relative to the current instruction address. For
368 I-form branches the effective address of the
369 branch target is the sum of the LI field
370 sign-extended to 64 bits and the address of
371 the branch instruction. For B-form branches
372 the effective address of the branch target is
373 the sum of the BD field sign-extended to 64
374 bits and the address of the branch instruction.
375 1 The immediate field represents an absolute
376 address. For I-form branches the effective
377 address of the branch target is the LI field
378 sign-extended to 64 bits. For B-form branches
379 the effective address of the branch target is
380 the BD field sign-extended to 64 bits.
381 Formats: B, I

398 BD (16:29)
399 Immediate field used to specify a 14-bit signed
400 two's complement branch displacement which is
401 concatenated on the right with 0b00 and
402 sign-extended to 64 bits.
403 Formats: B
404 BF (6:8)
405 Field used to specify one of the CR fields or one of
406 the FPSCR fields to be used as a target.
407 Formats: D, X, XL, XX2, XX3, Z22, CRB
408 BFA (22:24)
409 Field used to specify one of the CR fields
410 to be used as a source.
411 Formats: VA
412 BFA (29:31)
413 Field used to specify one of the CR fields or one of
414 the FPSCR fields to be used as a source.
415 Formats: EVS

428 described in Section 2.4, 'Branch Instructions'.
429 Formats: XL
430 BHRBE (11:20)
431 Field used to identify the BHRB entry to be used
432 as a source by the Move From Branch History
433 Rolling Buffer instruction.
434 Formats: XFX
435 BI (11:15)
436 Field used to specify a bit in the CR to be tested by
437 a Branch Conditional instruction.
438 Formats: B, X, XL
