1225 Use 'full compiler' when debugging is active. This should increase
1226 the density of possible break points, making single step more fine
1227 grained. This will only take effect for functions compiled after
1228 debugging has been started, so recompilation of all functions is
1229 required to get the full effect. IA32 and x64 only for now.

2507 Improved performance of Array.prototype.concat by moving the
2508 implementation to C++ (issue 123).
2509
2510 Fixed heap growth policy to avoid growing old space to its maximum
2511 capacity before doing a garbage collection and fixed issue that
2512 would lead to artificial out of memory situations (issue 129).

2533
2534
kasperl@chromium.org5a8ca6c2008-10-23 13:57:19 +000025352008-10-23: Version 0.4.0
2536
2537 Split the global object into two parts: The state holding global
2538 object and the global object proxy.
2539
2540 Fixed bug that affected the value of an assignment to an element
2541 in certain cases (issue 116).
2542
2543 Added GetPropertyNames functionality (issue 33) and extra Date
2544 functions (issue 77) to the API.
2545
2546 Changed WeakReferenceCallback to take a Persistent<Value> instead
2547 of a Persistent<Object> (issue 101).
2548
2549 Fixed issues with message reporting for exceptions in try-finally
2550 blocks (issues 73 and 75).

2561
2562
ager@chromium.org7c537e22008-10-16 08:43:32 +000025632008-10-16: Version 0.3.5
2564

2566 from the hash-code.
2567
2568 Changed string search algorithm used in indexOf from KMP to
2569 Boyer-Moore.
2570
2571 Improved the generated code for the instanceof operator.
2572
2573 Improved performance of slow-case string equality checks by
2574 specializing the code based on the string representation.
2575
2576 Improve the handling of out-of-memory situations (issue 70).
2577
2578 Improved performance of strict equality checks.
2579
2580 Improved profiler output to make it easier to see anonymous
2581 functions.

2586 properties in the front object.
2587
2588 Changed the toString behavior on the built-in object constructors
2589 to print [native code] instead of the actual source. Some web
2590 applications do not like constructors with complex toString
2591 results.

kasperl@chromium.org41044eb2008-10-06 08:24:46 +000025942008-10-06: Version 0.3.4
2595
2596 Changed Array.prototype.sort to use quick sort.
2597
2598 Fixed code generation issue where leaving a finally block with
2599 break or continue would accumulate elements on the expression
2600 stack (issue 86).
2601
2602 Made sure that the name accessor on functions returns the expected
2603 names for builtin JavaScript functions and C++ callback functions.
2604
2605 Added fast case code for extending the property storage array of
2606 JavaScript objects.
2607
2608 Ported switch statement optimizations introduced in version 0.3.3
2609 to the ARM code generator.
2610
2611 Allowed GCC to use strict-aliasing rules when compiling.
2612
2613 Improved performance of arguments object allocation by taking care
2614 of arguments adaptor frames in the generated code.
2615
2616 Updated the V8 benchmark suite to version 2.
2617
2618
ager@chromium.org236ad962008-09-25 09:45:57 +000026192008-09-25: Version 0.3.3
2620
2621 Improved handling of relocation information to enable more
2622 peep-hole optimizations.
2623
2624 Optimized switch statements where all labels are constant small
2625 integers.
2626
2627 Optimized String.prototype.indexOf for common cases.
2628
2629 Fixed more build issues (issue 80).
2630
2631 Fixed a couple of profiler issues.
2632
2633 Fixed bug where the body of a function created using the Function
2634 constructor was not allowed to end with a single-line comment
2635 (issue 85).
2636
2637 Improved handling of object literals by canonicalizing object
2638 literal maps. This will allow JSON objects with the same set of
2639 properties to share the same map making inline caching work better
2640 for JSON objects.

2644
2645 Generalized the EvalCache into a CompilationCache and enabled it
2646 for scripts too. The current strategy is to retire all entries
2647 whenever a mark-sweep collection is started.
2648
2649 Fixed bug where switch statements containing only a default case
2650 would lead to an unbalanced stack (issue 69).
2651
2652 Fixed bug that made access to the function in a named function
2653 expression impossible in certain situations (issue 24).
2654
2655 Fixed even more build issues.
2656
2657 Optimized calling conventions on ARM. The conventions on ARM and
2658 IA-32 now match.
2659
2660 Removed static initializers for flags and counters.
2661
2662 Improved inline caching behavior for uncommon cases where lazily
2663 loading Date and RegExp code could force certain code paths go
2664 megamorphic.
2665
2666 Removed arguments adaption for builtins written in C++. This
2667 makes Array.prototype.push and Array.prototype.pop slightly
2668 faster.
2669
2670
ager@chromium.org9258b6b2008-09-11 09:11:10 +000026712008-09-11: Version 0.3.1
2672
2673 Fixed a number of build issues.
2674
2675 Fixed problem with missing I-cache flusing on ARM.
2676
2677 Changed space layout in memory management by splitting up
2678 code space into old data space and code space.
2679
2680 Added utf-8 conversion support to the API (issue 57).
2681
2682 Optimized repeated calls to eval with the same strings. These
2683 repeated calls are common in web applications.
2684
2685 Added Xcode project file.
2686
2687 Optimized a couple of Array operation.
2688
2689 Fixed parser bug by checking for end-of-string when parsing break
2690 and continue (issue 35).
2691
2692 Fixed problem where asian characters were not categorized as
2693 letters.
2694
2695 Fixed bug that disallowed calling functions fetched from an array
2696 using a string as an array index (issue 32).
2697
2698 Fixed bug where the internal field count on object templates were
2699 sometimes ignored (issue 54).
2700
2701 Added -f option to the shell sample for compatibility with other
2702 engines (issue 18).
2703
2704 Added source info to TryCatches in the API.
2705
2706 Fixed problem where the seed for the random number generator was
2707 clipped in a double to unsigned int conversion.
2708
2709 Fixed bug where cons string symbols were sometimes converted to
2710 non-symbol flat strings during GC.
2711
2712 Fixed bug in error reporting when attempting to convert null to an
2713 object.
ager@chromium.org32912102009-01-16 10:38:43 +00002714

ager@chromium.orgc27e4e72008-09-04 13:52:27 +000027162008-09-04: Version 0.3.0
2717
2718 Added support for running tests on the ARM simulator.
2719
2720 Fixed bug in the 'in' operator where negative indices were not
2721 treated correctly.
2722
2723 Fixed build issues on gcc-4.3.1.
2724
2725 Changed Date.prototype.toLocaleTimeString to not print the
2726 timezone part of the time.
2727
2728 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
2729 with user code.
2730
2731
v8.team.kasperl727e9952008-09-02 14:56:44 +000027322008-09-02: Version 0.2.5
2733
2734 Renamed the top level directory 'public' to 'include'.
2735
2736 Added 'env' option to the SCons build scripts to support
2737 overriding the ENV part of the build environment. This is mostly
2738 to support Windows builds in cases where SCons cannot find the
2739 correct paths to the Windows SDK, as these paths cannot be passed
2740 through shell environment variables.
2741
2742 Enabled "Buffer Security Check" on for the Windows SCons build and
2743 added the linker option /OPT:ICF as an optimization.
2744
2745 Added the V8 benchmark suite to the repository.
2746
2747
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000027482008-09-01: Version 0.2.4
2749
2750 Included mjsunit JavaScript test suite and C++ unit tests.
2751
2752 Changed the shell sample to not print the result of executing a
2753 script provided on the command line.
2754
2755 Fixed issue when building samples on Windows using a shared V8
2756 library. Added visibility option on Linux build which makes the
2757 generated library 18% smaller.
2758
2759 Changed build system to accept multiple build modes in one build
2760 and generate separate objects, libraries and executables for each
2761 mode.
2762
2763 Removed deferred negation optimization (a * -b => -(a * b)) since
2764 this visibly changes operand conversion order.
2765
2766 Improved parsing performance by introducing stack guard in
2767 preparsing. Without a stack guard preparsing always bails out
2768 with stack overflow.
2769
2770 Changed shell sample to take flags directly from the command-line.
2771 Added API call that implements this.
2772
2773 Added load, quit and version functions to the shell sample so it's
2774 easier to run benchmarks and tests.
2775
2776 Fixed issue with building samples and cctests on 64-bit machines.
2777
2778 Fixed bug in the runtime system where the prototype chain was not
2779 always searched for a setter when setting a property that does not
2780 exist locally.

mads.s.agercbaa0602008-08-14 13:41:48 +000027832008-08-14: Version 0.2.3
2784
2785 Improved performance of garbage collection by moving the
2786 function that updates pointers during compacting collection
2787 into the updating visitor. This gives the compiler a better
2788 chance to inline and avoid a function call per (potential)
2789 pointer.
2790
2791 Extended the shell sample with a --runtime-flags option.
2792
2793 Added Visual Studio project files for the shell.cc and
2794 process.cc samples.
2795
2796
27972008-08-13: Version 0.2.2
mads.s.ager31e71382008-08-13 09:32:07 +00002798
2799 Improved performance of garbage collection by changing the way
2800 we use the marking stack in the event of stack overflow during
2801 full garbage collection and by changing the way we mark roots.
2802
2803 Cleaned up ARM version by removing top of stack caching and by
2804 introducing push/pop elimination.
2805
2806 Cleaned up the way runtime functions are called to allow
2807 runtime calls with no arguments.
2808
2809 Changed Windows build options to make sure that exceptions are
2810 disabled and that optimization flags are enabled.
2811
2812 Added first version of Visual Studio project files.
2813
2814
mads.s.agercbaa0602008-08-14 13:41:48 +000028152008-08-06: Version 0.2.1
mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00002816
2817 Improved performance of unary addition by avoiding runtime calls.
2818
2819 Fixed the handling of '>' and '<=' to use right-to-left conversion
2820 and left-to-right evaluation as specified by ECMA-262.
2821
2822 Fixed a branch elimination bug on the ARM platform where incorrect
2823 code was generated because of overly aggressive branch
2824 elimination.
2825
2826 Improved performance of code that repeatedly assigns the same
2827 function to the same property of different objects with the same
2828 map.
2829
2830 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
2831 no longer expects DEBUG to be defined.
2832
2833 Added platform-nullos.cc to serve as the basis for new platform
2834 implementations.
2835

kasper.lund7276f142008-07-30 08:49:36 +00002838
2839 Changed all text files to have native svn:eol-style.
2840
2841 Added a few samples and support for building them. The samples
2842 include a simple shell that can be used to benchmark and test V8.
2843
2844 Changed V8::GetVersion to return the version as a string.
2845
2846 Added source for lazily loaded scripts to snapshots and made
2847 serialization non-destructive.
2848
2849 Improved ARM support by fixing the write barrier code to use
2850 aligned loads and stores and by removing premature locals
2851 optimization that relied on broken support for callee-saved
2852 registers (removed).
2853
2854 Refactored the code for marking live objects during garbage
2855 collection and the code for allocating objects in paged
2856 spaces. Introduced an abstraction for the map word of a heap-
2857 allocated object and changed the memory allocator to allocate
2858 executable memory only for spaces that may contain code objects.
2859
2860 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
2861 they can be used by debugging and logging modules. Added
2862 thread-safe message queues for dealing with debugger events.
2863
2864 Fixed the source code reported by toString for certain builtin
2865 empty functions and made sure that the prototype property of a
2866 function is enumerable.
2867
2868 Improved performance of converting values to condition flags in
2869 generated code.
2870
2871 Merged disassembler-{arch} files.
2872
2873

kasper.lundaf4734f2008-07-28 12:50:18 +00002875
2876 Added support for storing JavaScript stack traces in a stack
2877 allocated buffer to make it visible in shallow core dumps.
2878 Controlled by the --preallocate-message-memory flag which is
2879 disabled by default.
2880
2881
mads.s.agercbaa0602008-08-14 13:41:48 +000028822008-07-25: Version 0.1.3
kasper.lund44510672008-07-25 07:37:58 +00002883
2884 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
2885 map transitions would count as properties.
2886
2887 Allowed aliased eval invocations by treating them as evals in the
2888 global context. This may change in the future.
2889
2890 Added support for accessing the last entered context through the
2891 API and renamed Context::Current to Context::GetCurrent and
2892 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
2893
2894 Fixed bug in the debugger that would cause the debugger scripts to
2895 be recursively loaded and changed all disabling of interrupts to
2896 be block-structured.
2897
2898 Made snapshot data read-only to allow it to be more easily shared
2899 across multiple users of V8 when linked as a shared library.
2900
2901
mads.s.agercbaa0602008-08-14 13:41:48 +000029022008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00002903
2904 Fixed building on Mac OS X by recognizing i386 and friends as
2905 IA-32 platforms.
2906
2907 Added propagation of stack overflow exceptions that occur while
2908 compiling nested functions.
2909
2910 Improved debugger with support for recursive break points and
2911 handling of exceptions that occur in the debugger JavaScript code.
2912
2913 Renamed GetInternal to GetInternalField and SetInternal to
2914 SetInternalField in the API and moved InternalFieldCount and
2915 SetInternalFieldCount from FunctionTemplate to ObjectTemplate.
2916
2917
mads.s.agercbaa0602008-08-14 13:41:48 +000029182008-07-09: Version 0.1.1
kasper.lundbd3ec4e2008-07-09 11:06:54 +00002919
2920 Fixed bug in stack overflow check code for IA-32 targets where a
2921 non-tagged value in register eax was pushed to the stack.
2922
2923 Fixed potential quadratic behavior when converting strings to
2924 numbers.
2925
2926 Fixed bug where the return value from Object::SetProperty could
2927 end up being the property holder instead of the written value.
2928
2929 Improved debugger support by allowing nested break points and by
2930 dealing with stack-overflows when compiling functions before
2931 setting break points in them.
2932
2933
