| 383 | |
| 384 | Changed Array.prototype.sort to use quick sort. |
| 385 | |
| 386 | Fixed code generation issue where leaving a finally block with |
| 387 | break or continue would accumulate elements on the expression |
| 388 | stack (issue 86). |
| 389 | |
| 390 | Made sure that the name accessor on functions returns the expected |
| 391 | names for builtin JavaScript functions and C++ callback functions. |
| 392 | |
| 393 | Added fast case code for extending the property storage array of |
| 394 | JavaScript objects. |
| 395 | |
| 396 | Ported switch statement optimizations introduced in version 0.3.3 |
| 397 | to the ARM code generator. |
| 398 | |
| 399 | Allowed GCC to use strict-aliasing rules when compiling. |
| 400 | |
| 401 | Improved performance of arguments object allocation by taking care |
| 402 | of arguments adaptor frames in the generated code. |
| 403 | |
| 404 | Updated the V8 benchmark suite to version 2. |
| 405 | |
| 406 | |

| 408 | |
| 409 | Improved handling of relocation information to enable more |
| 410 | peep-hole optimizations. |
| 411 | |
| 412 | Optimized switch statements where all labels are constant small |
| 413 | integers. |
| 414 | |
| 415 | Optimized String.prototype.indexOf for common cases. |
| 416 | |
| 417 | Fixed more build issues (issue 80). |
| 418 | |
| 419 | Fixed a couple of profiler issues. |
| 420 | |
| 421 | Fixed bug where the body of a function created using the Function |
| 422 | constructor was not allowed to end with a single-line comment |
| 423 | (issue 85). |
| 424 | |
| 425 | Improved handling of object literals by canonicalizing object |
| 426 | literal maps. This will allow JSON objects with the same set of |
| 427 | properties to share the same map making inline caching work better |
| 428 | for JSON objects. |

| 432 | |
| 433 | Generalized the EvalCache into a CompilationCache and enabled it |
| 434 | for scripts too. The current strategy is to retire all entries |
| 435 | whenever a mark-sweep collection is started. |
| 436 | |
| 437 | Fixed bug where switch statements containing only a default case |
| 438 | would lead to an unbalanced stack (issue 69). |
| 439 | |
| 440 | Fixed bug that made access to the function in a named function |
| 441 | expression impossible in certain situations (issue 24). |
| 442 | |
| 443 | Fixed even more build issues. |
| 444 | |
| 445 | Optimized calling conventions on ARM. The conventions on ARM and |
| 446 | IA-32 now match. |
| 447 | |
| 448 | Removed static initializers for flags and counters. |
| 449 | |
| 450 | Improved inline caching behavior for uncommon cases where lazily |
| 451 | loading Date and RegExp code could force certain code paths go |
| 452 | megamorphic. |
| 453 | |
| 454 | Removed arguments adaption for builtins written in C++. This |
| 455 | makes Array.prototype.push and Array.prototype.pop slightly |
| 456 | faster. |
| 457 | |
| 458 | |

| 460 | |
| 461 | Fixed a number of build issues. |
| 462 | |
| 463 | Fixed problem with missing I-cache flusing on ARM. |
| 464 | |
| 465 | Changed space layout in memory management by splitting up |
| 466 | code space into old data space and code space. |
| 467 | |
| 468 | Added utf-8 conversion support to the API (issue 57). |
| 469 | |
| 470 | Optimized repeated calls to eval with the same strings. These |
| 471 | repeated calls are common in web applications. |
| 472 | |
| 473 | Added Xcode project file. |
| 474 | |
| 475 | Optimized a couple of Array operation. |
| 476 | |
| 477 | Fixed parser bug by checking for end-of-string when parsing break |
| 478 | and continue (issue 35). |
| 479 | |
| 480 | Fixed problem where asian characters were not categorized as |
| 481 | letters. |
| 482 | |
| 483 | Fixed bug that disallowed calling functions fetched from an array |
| 484 | using a string as an array index (issue 32). |
| 485 | |
| 486 | Fixed bug where the internal field count on object templates were |
| 487 | sometimes ignored (issue 54). |
| 488 | |
| 489 | Added -f option to the shell sample for compatibility with other |
| 490 | engines (issue 18). |
| 491 | |
| 492 | Added source info to TryCatches in the API. |
| 493 | |
| 494 | Fixed problem where the seed for the random number generator was |
| 495 | clipped in a double to unsigned int conversion. |
| 496 | |
| 497 | Fixed bug where cons string symbols were sometimes converted to |
| 498 | non-symbol flat strings during GC. |
| 499 | |
| 500 | Fixed bug in error reporting when attempting to convert null to an |
| 501 | object. |

| 505 | |
| 506 | Added support for running tests on the ARM simulator. |
| 507 | |
| 508 | Fixed bug in the 'in' operator where negative indices were not |
| 509 | treated correctly. |
| 510 | |
| 511 | Fixed build issues on gcc-4.3.1. |
| 512 | |
| 513 | Changed Date.prototype.toLocaleTimeString to not print the |
| 514 | timezone part of the time. |
| 515 | |
| 516 | Renamed debug.h to v8-debug.h to reduce the risk of name conflicts |
| 517 | with user code. |
| 518 | |
| 519 | |
v8.team.kasperl | 727e995 | 2008-09-02 14:56:44 +0000 | [diff] [blame] | 520 | 2008-09-02: Version 0.2.5 |
| 521 | |
| 522 | Renamed the top level directory 'public' to 'include'. |
| 523 | |
| 524 | Added 'env' option to the SCons build scripts to support |
| 525 | overriding the ENV part of the build environment. This is mostly |
| 526 | to support Windows builds in cases where SCons cannot find the |
| 527 | correct paths to the Windows SDK, as these paths cannot be passed |
| 528 | through shell environment variables. |
| 529 | |
| 530 | Enabled "Buffer Security Check" on for the Windows SCons build and |
| 531 | added the linker option /OPT:ICF as an optimization. |
| 532 | |
| 533 | Added the V8 benchmark suite to the repository. |
| 534 | |
| 535 | |
mads.s.ager@gmail.com | 9a4089a | 2008-09-01 08:55:01 +0000 | [diff] [blame] | 536 | 2008-09-01: Version 0.2.4 |
| 537 | |
| 538 | Included mjsunit JavaScript test suite and C++ unit tests. |
| 539 | |
| 540 | Changed the shell sample to not print the result of executing a |
| 541 | script provided on the command line. |
| 542 | |
| 543 | Fixed issue when building samples on Windows using a shared V8 |
| 544 | library. Added visibility option on Linux build which makes the |
| 545 | generated library 18% smaller. |
| 546 | |
| 547 | Changed build system to accept multiple build modes in one build |
| 548 | and generate separate objects, libraries and executables for each |
| 549 | mode. |
| 550 | |
| 551 | Removed deferred negation optimization (a * -b => -(a * b)) since |
| 552 | this visibly changes operand conversion order. |
| 553 | |
| 554 | Improved parsing performance by introducing stack guard in |
| 555 | preparsing. Without a stack guard preparsing always bails out |
| 556 | with stack overflow. |
| 557 | |
| 558 | Changed shell sample to take flags directly from the command-line. |
| 559 | Added API call that implements this. |
| 560 | |
| 561 | Added load, quit and version functions to the shell sample so it's |
| 562 | easier to run benchmarks and tests. |
| 563 | |
| 564 | Fixed issue with building samples and cctests on 64-bit machines. |
| 565 | |
| 566 | Fixed bug in the runtime system where the prototype chain was not |
| 567 | always searched for a setter when setting a property that does not |
| 568 | exist locally. |

mads.s.ager | cbaa060 | 2008-08-14 13:41:48 +0000 | [diff] [blame] | 571 | 2008-08-14: Version 0.2.3 |
| 572 | |
| 573 | Improved performance of garbage collection by moving the |
| 574 | function that updates pointers during compacting collection |
| 575 | into the updating visitor. This gives the compiler a better |
| 576 | chance to inline and avoid a function call per (potential) |
| 577 | pointer. |
| 578 | |
| 579 | Extended the shell sample with a --runtime-flags option. |
| 580 | |
| 581 | Added Visual Studio project files for the shell.cc and |
| 582 | process.cc samples. |
| 583 | |
| 584 | |
| 585 | 2008-08-13: Version 0.2.2 |
mads.s.ager | 31e7138 | 2008-08-13 09:32:07 +0000 | [diff] [blame] | 586 | |
| 587 | Improved performance of garbage collection by changing the way |
| 588 | we use the marking stack in the event of stack overflow during |
| 589 | full garbage collection and by changing the way we mark roots. |
| 590 | |
| 591 | Cleaned up ARM version by removing top of stack caching and by |
| 592 | introducing push/pop elimination. |
| 593 | |
| 594 | Cleaned up the way runtime functions are called to allow |
| 595 | runtime calls with no arguments. |
| 596 | |
| 597 | Changed Windows build options to make sure that exceptions are |
| 598 | disabled and that optimization flags are enabled. |
| 599 | |
| 600 | Added first version of Visual Studio project files. |
| 601 | |
| 602 | |

mads.s.ager@gmail.com | 769cc96 | 2008-08-06 10:02:49 +0000 | [diff] [blame] | 604 | |
| 605 | Improved performance of unary addition by avoiding runtime calls. |
| 606 | |
| 607 | Fixed the handling of '>' and '<=' to use right-to-left conversion |
| 608 | and left-to-right evaluation as specified by ECMA-262. |
| 609 | |
| 610 | Fixed a branch elimination bug on the ARM platform where incorrect |
| 611 | code was generated because of overly aggressive branch |
| 612 | elimination. |
| 613 | |
| 614 | Improved performance of code that repeatedly assigns the same |
| 615 | function to the same property of different objects with the same |
| 616 | map. |
| 617 | |
| 618 | Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| 619 | no longer expects DEBUG to be defined. |
| 620 | |
| 621 | Added platform-nullos.cc to serve as the basis for new platform |
| 622 | implementations. |
| 623 | |

kasper.lund | 7276f14 | 2008-07-30 08:49:36 +0000 | [diff] [blame] | 626 | |
| 627 | Changed all text files to have native svn:eol-style. |
| 628 | |
| 629 | Added a few samples and support for building them. The samples |
| 630 | include a simple shell that can be used to benchmark and test V8. |
| 631 | |
| 632 | Changed V8::GetVersion to return the version as a string. |
| 633 | |
| 634 | Added source for lazily loaded scripts to snapshots and made |
| 635 | serialization non-destructive. |
| 636 | |
| 637 | Improved ARM support by fixing the write barrier code to use |
| 638 | aligned loads and stores and by removing premature locals |
| 639 | optimization that relied on broken support for callee-saved |
| 640 | registers (removed). |
| 641 | |
| 642 | Refactored the code for marking live objects during garbage |
| 643 | collection and the code for allocating objects in paged |
| 644 | spaces. Introduced an abstraction for the map word of a heap- |
| 645 | allocated object and changed the memory allocator to allocate |
| 646 | executable memory only for spaces that may contain code objects. |
| 647 | |
| 648 | Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| 649 | they can be used by debugging and logging modules. Added |
| 650 | thread-safe message queues for dealing with debugger events. |
| 651 | |
| 652 | Fixed the source code reported by toString for certain builtin |
| 653 | empty functions and made sure that the prototype property of a |
| 654 | function is enumerable. |
| 655 | |
| 656 | Improved performance of converting values to condition flags in |
| 657 | generated code. |
| 658 | |
| 659 | Merged disassembler-{arch} files. |
| 660 | |
| 661 | |

kasper.lund | af4734f | 2008-07-28 12:50:18 +0000 | [diff] [blame] | 663 | |
| 664 | Added support for storing JavaScript stack traces in a stack |
| 665 | allocated buffer to make it visible in shallow core dumps. |
| 666 | Controlled by the --preallocate-message-memory flag which is |
| 667 | disabled by default. |
| 668 | |
| 669 | |
mads.s.ager | cbaa060 | 2008-08-14 13:41:48 +0000 | [diff] [blame] | 670 | 2008-07-25: Version 0.1.3 |
kasper.lund | 4451067 | 2008-07-25 07:37:58 +0000 | [diff] [blame] | 671 | |
| 672 | Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| 673 | map transitions would count as properties. |
| 674 | |
| 675 | Allowed aliased eval invocations by treating them as evals in the |
| 676 | global context. This may change in the future. |
| 677 | |
| 678 | Added support for accessing the last entered context through the |
| 679 | API and renamed Context::Current to Context::GetCurrent and |
| 680 | Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| 681 | |
| 682 | Fixed bug in the debugger that would cause the debugger scripts to |
| 683 | be recursively loaded and changed all disabling of interrupts to |
| 684 | be block-structured. |
| 685 | |
| 686 | Made snapshot data read-only to allow it to be more easily shared |
| 687 | across multiple users of V8 when linked as a shared library. |
| 688 | |
| 689 | |
mads.s.ager | cbaa060 | 2008-08-14 13:41:48 +0000 | [diff] [blame] | 690 | 2008-07-16: Version 0.1.2 |
kasper.lund | 212ac23 | 2008-07-16 07:07:30 +0000 | [diff] [blame] | 691 | |
| 692 | Fixed building on Mac OS X by recognizing i386 and friends as |
| 693 | IA-32 platforms. |
| 694 | |
| 695 | Added propagation of stack overflow exceptions that occur while |
| 696 | compiling nested functions. |
| 697 | |
| 698 | Improved debugger with support for recursive break points and |
| 699 | handling of exceptions that occur in the debugger JavaScript code. |
| 700 | |
| 701 | Renamed GetInternal to GetInternalField and SetInternal to |
| 702 | SetInternalField in the API and moved InternalFieldCount and |
| 703 | SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
| 704 | |
| 705 | |

kasper.lund | bd3ec4e | 2008-07-09 11:06:54 +0000 | [diff] [blame] | 707 | |
| 708 | Fixed bug in stack overflow check code for IA-32 targets where a |
| 709 | non-tagged value in register eax was pushed to the stack. |
| 710 | |
| 711 | Fixed potential quadratic behavior when converting strings to |
| 712 | numbers. |
| 713 | |
| 714 | Fixed bug where the return value from Object::SetProperty could |
| 715 | end up being the property holder instead of the written value. |
| 716 | |
| 717 | Improved debugger support by allowing nested break points and by |
| 718 | dealing with stack-overflows when compiling functions before |
| 719 | setting break points in them. |
| 720 | |
| 721 | |
