A four-word thunk is used to record 329 details of the most recent flag-setting operation, so the flags can 330 be computed later if needed. It is possible to do this a little 331 more efficiently using a 3-word thunk, but that makes it impossible 332 to describe the flag data dependencies sufficiently accurately for 333 Memcheck. Hence 4 words are used, with minimal loss of efficiency. 334 335 The four words are: 336 337 CC_OP, which describes the operation. 338 339 CC_DEP1 and CC_DEP2. These are arguments to the operation. 340 We want Memcheck to believe that the resulting flags are 341 data-dependent on both CC_DEP1 and CC_DEP2, hence the 342 name DEP. 343 344 CC_NDEP. This is a 3rd argument to the operation which is 345 sometimes needed. We arrange things so that Memcheck does 346 not believe the resulting flags are data-dependent on CC_NDEP 347 ("not dependent"). 348 349 To make Memcheck believe that (the definedness of) the encoded 350 flags depends only on (the definedness of) CC_DEP1 and CC_DEP2 351 requires two things: 352 353 (1) In the guest state layout info (amd64guest_layout), CC_OP and 354 CC_NDEP are marked as always defined. 355 356 (2) When passing the thunk components to an evaluation function 357 (calculate_condition, calculate_eflags, calculate_eflags_c) the 358 IRCallee's mcx_mask must be set so as to exclude from 359 consideration all passed args except CC_DEP1 and CC_DEP2. 360 361 Strictly speaking only (2) is necessary for correctness. However, 362 (1) helps efficiency in that since (2) means we never ask about the 363 definedness of CC_OP or CC_NDEP, we may as well not even bother to 364 track their definedness. 365 366 When building the thunk, it is always necessary to write words into 367 CC_DEP1 and CC_DEP2, even if those args are not used given the 368 CC_OP field (eg, CC_DEP2 is not used if CC_OP is CC_LOGIC1/2/4). 369 This is important because otherwise Memcheck could give false 370 positives as it does not understand the relationship between the 371 CC_OP field and CC_DEP1 and CC_DEP2, and so believes that the 372 definedness of the stored flags always depends on both CC_DEP1 and 373 CC_DEP2. 374 375 However, it is only necessary to set CC_NDEP when the CC_OP value 376 requires it, because Memcheck ignores CC_NDEP, and the evaluation 377 functions do understand the CC_OP fields and will only examine 378 CC_NDEP for suitable values of CC_OP. 379 380 A summary of the field usages is: 381 382 Operation DEP1 DEP2 NDEP 383 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 384 385 add/sub/mul first arg second arg unused 386 387 adc/sbb first arg (second arg) 388 XOR old_carry old_carry 389 390 and/or/xor result zero unused 391 392 inc/dec result zero old_carry 393 394 shl/shr/sar result subshifted- unused 395 result 396 397 rol/ror result zero old_flags 398 399 copy old_flags zero unused. 400 401 402 Therefore Memcheck will believe the following: 403 404 * add/sub/mul -- definedness of result flags depends on definedness 405 of both args. 406 407 * adc/sbb -- definedness of result flags depends on definedness of 408 both args and definedness of the old C flag. Because only two 409 DEP fields are available, the old C flag is XOR'd into the second 410 arg so that Memcheck sees the data dependency on it. That means 411 the NDEP field must contain a second copy of the old C flag 412 so that the evaluation functions can correctly recover the second 413 arg. 414 415 * and/or/xor are straightforward -- definedness of result flags 416 depends on definedness of result value. 417 418 * inc/dec -- definedness of result flags depends only on 419 definedness of result. This isn't really true -- it also depends 420 on the old C flag. However, we don't want Memcheck to see that, 421 and so the old C flag must be passed in NDEP and not in DEP2. 422 It's inconceivable that a compiler would generate code that puts 423 the C flag in an undefined state, then does an inc/dec, which 424 leaves C unchanged, and then makes a conditional jump/move based 425 on C. So our fiction seems a good approximation. 426 427 * shl/shr/sar -- straightforward, again, definedness of result 428 flags depends on definedness of result value. The subshifted 429 value (value shifted one less) is also needed, but its 430 definedness is the same as the definedness of the shifted value. 431 432 * rol/ror -- these only set O and C, and leave A Z C P alone. 433 However it seems prudent (as per inc/dec) to say the definedness 434 of all resulting flags depends on the definedness of the result, 435 hence the old flags must go in as NDEP and not DEP2. 436 437 * rcl/rcr are too difficult to do in-line, and so are done by a 438 helper function. They are not part of this scheme. The helper 439 function takes the value to be rotated, the rotate amount and the 440 old flags, and returns the new flags and the rotated value. 441 Since the helper's mcx_mask does not have any set bits, Memcheck 442 will lazily propagate undefinedness from any of the 3 args into 443 both results (flags and actual value). 444 */ 445 enum { 446 AMD64G_CC_OP_COPY=0, /* DEP1 = current flags, DEP2 = 0, NDEP = unused */ 447 /* just copy DEP1 to output */ 448 449 AMD64G_CC_OP_ADDB, /* 1 */ 450 AMD64G_CC_OP_ADDW, /* 2 DEP1 = argL, DEP2 = argR, NDEP = unused */ 451 AMD64G_CC_OP_ADDL, /* 3 */ 452 AMD64G_CC_OP_ADDQ, /* 4 */ 453 454 AMD64G_CC_OP_SUBB, /* 5 */ 455 AMD64G_CC_OP_SUBW, /* 6 DEP1 = argL, DEP2 = argR, NDEP = unused */ 456 AMD64G_CC_OP_SUBL, /* 7 */ 457 AMD64G_CC_OP_SUBQ, /* 8 */ 458 459 AMD64G_CC_OP_ADCB, /* 9 */ 460 AMD64G_CC_OP_ADCW, /* 10 DEP1 = argL, DEP2 = argR ^ oldCarry, NDEP = oldCarry */ 461 AMD64G_CC_OP_ADCL, /* 11 */ 462 AMD64G_CC_OP_ADCQ, /* 12 */ 463 464 AMD64G_CC_OP_SBBB, /* 13 */ 465 AMD64G_CC_OP_SBBW, /* 14 DEP1 = argL, DEP2 = argR ^ oldCarry, NDEP = oldCarry */ 466 AMD64G_CC_OP_SBBL, /* 15 */ 467 AMD64G_CC_OP_SBBQ, /* 16 */ 468 469 AMD64G_CC_OP_LOGICB, /* 17 */ 470 AMD64G_CC_OP_LOGICW, /* 18 DEP1 = result, DEP2 = 0, NDEP = unused */ 471 AMD64G_CC_OP_LOGICL, /* 19 */ 472 AMD64G_CC_OP_LOGICQ, /* 20 */ 473 474 AMD64G_CC_OP_INCB, /* 21 */ 475 AMD64G_CC_OP_INCW, /* 22 DEP1 = result, DEP2 = 0, NDEP = oldCarry (0 or 1) */ 476 AMD64G_CC_OP_INCL, /* 23 */ 477 AMD64G_CC_OP_INCQ, /* 24 */ 478 479 AMD64G_CC_OP_DECB, /* 25 */ 480 AMD64G_CC_OP_DECW, /* 26 DEP1 = result, DEP2 = 0, NDEP = oldCarry (0 or 1) */ 481 AMD64G_CC_OP_DECL, /* 27 */ 482 AMD64G_CC_OP_DECQ, /* 28 */ 483 484 AMD64G_CC_OP_SHLB, /* 29 DEP1 = res, DEP2 = res', NDEP = unused */ 485 AMD64G_CC_OP_SHLW, /* 30 where res' is like res but shifted one bit less */ 486 AMD64G_CC_OP_SHLL, /* 31 */ 487 AMD64G_CC_OP_SHLQ, /* 32 */ 488 489 AMD64G_CC_OP_SHRB, /* 33 DEP1 = res, DEP2 = res', NDEP = unused */ 490 AMD64G_CC_OP_SHRW, /* 34 where res' is like res but shifted one bit less */ 491 AMD64G_CC_OP_SHRL, /* 35 */ 492 AMD64G_CC_OP_SHRQ, /* 36 */ 493 494 AMD64G_CC_OP_ROLB, /* 37 */ 495 AMD64G_CC_OP_ROLW, /* 38 DEP1 = res, DEP2 = 0, NDEP = old flags */ 496 AMD64G_CC_OP_ROLL, /* 39 */ 497 AMD64G_CC_OP_ROLQ, /* 40 */ 498 499 AMD64G_CC_OP_RORB, /* 41 */ 500 AMD64G_CC_OP_RORW, /* 42 DEP1 = res, DEP2 = 0, NDEP = old flags */ 501 AMD64G_CC_OP_RORL, /* 43 */ 502 AMD64G_CC_OP_RORQ, /* 44 */ 503 504 AMD64G_CC_OP_UMULB, /* 45 */ 505 AMD64G_CC_OP_UMULW, /* 46 DEP1 = argL, DEP2 = argR, NDEP = unused */ 506 AMD64G_CC_OP_UMULL, /* 47 */ 507 AMD64G_CC_OP_UMULQ, /* 48 */ 508 509 AMD64G_CC_OP_SMULB, /* 49 */ 510 AMD64G_CC_OP_SMULW, /* 50 DEP1 = argL, DEP2 = argR, NDEP = unused */ 511 AMD64G_CC_OP_SMULL, /* 51 */ 512 AMD64G_CC_OP_SMULQ, /* 52 */ 513 514 AMD64G_CC_OP_ANDN32, /* 53 */ 515 AMD64G_CC_OP_ANDN64, /* 54 DEP1 = res, DEP2 = 0, NDEP = unused */ 516 517 AMD64G_CC_OP_BLSI32, /* 55 */ 518 AMD64G_CC_OP_BLSI64, /* 56 DEP1 = res, DEP2 = arg, NDEP = unused */ 519 520 AMD64G_CC_OP_BLSMSK32,/* 57 */ 521 AMD64G_CC_OP_BLSMSK64,/* 58 DEP1 = res, DEP2 = arg, NDEP = unused */ 522 523 AMD64G_CC_OP_BLSR32, /* 59 */ 524 AMD64G_CC_OP_BLSR64, /* 60 DEP1 = res, DEP2 = arg, NDEP = unused */ 525 526 AMD64G_CC_OP_NUMBER 527 }; 528 529 typedef 530 enum { 531 AMD64CondO = 0, /* overflow */ 532 AMD64CondNO = 1, /* no overflow */ 533 534 AMD64CondB = 2, /* below */ 535 AMD64CondNB = 3, /* not below */ 536 537 AMD64CondZ = 4, /* zero */ 538 AMD64CondNZ = 5, /* not zero */ 539 540 AMD64CondBE = 6, /* below or equal */ 541 AMD64CondNBE = 7, /* not below or equal */ 542 543 AMD64CondS = 8, /* negative */ 544 AMD64CondNS = 9, /* not negative */ 545 546 AMD64CondP = 10, /* parity even */ 547 AMD64CondNP = 11, /* not parity even */ 548 549 AMD64CondL = 12, /* jump less */ 550 AMD64CondNL = 13, /* not less */ 551 552 AMD64CondLE = 14, /* less or equal */ 553 AMD64CondNLE = 15, /* not less or equal */ 554 555 AMD64CondAlways = 16 /* HACK */ 556 } 557 AMD64Condcode; 558 559 #endif /* ndef __VEX_GUEST_AMD64_DEFS_H */ 560 561 /*---------------------------------------------------------------*/ 562 /*--- end guest_amd64_defs.h ---*/ 563 /*---------------------------------------------------------------*/ 564
