4491 the density of possible break points, making single step more fine
4492 grained. This will only take effect for functions compiled after

5792
5793 Fixed function call performance regression introduced in version
5794 0.4.0 when splitting the global object in two parts (issue 120).
5795

kasperl@chromium.org5a8ca6c2008-10-23 13:57:19 +000058002008-10-23: Version 0.4.0
5801
5802 Split the global object into two parts: The state holding global
5803 object and the global object proxy.
5804
5805 Fixed bug that affected the value of an assignment to an element
5806 in certain cases (issue 116).
5807
5808 Added GetPropertyNames functionality (issue 33) and extra Date
5809 functions (issue 77) to the API.
5810
5811 Changed WeakReferenceCallback to take a Persistent<Value> instead
5812 of a Persistent<Object> (issue 101).
5813
5814 Fixed issues with message reporting for exceptions in try-finally
5815 blocks (issues 73 and 75).
5816
ager@chromium.org32912102009-01-16 10:38:43 +00005817 Optimized flattening of strings and string equality checking.
kasperl@chromium.org5a8ca6c2008-10-23 13:57:19 +00005818

5822 completion support.
5823
5824 Fixed problem with the receiver passed to functions called from
5825 eval (issue 124).
5826
5827
ager@chromium.org7c537e22008-10-16 08:43:32 +000058282008-10-16: Version 0.3.5
5829
5830 Improved string hash-code distribution by excluding bit-field bits
5831 from the hash-code.
5832
5833 Changed string search algorithm used in indexOf from KMP to
5834 Boyer-Moore.
5835
5836 Improved the generated code for the instanceof operator.
5837
5838 Improved performance of slow-case string equality checks by
5839 specializing the code based on the string representation.
5840
5841 Improve the handling of out-of-memory situations (issue 70).
5842
5843 Improved performance of strict equality checks.
5844
5845 Improved profiler output to make it easier to see anonymous
5846 functions.
5847
5848 Improved performance of slow-case keyed loads.
5849
5850 Improved property access performance by allocating a number of
5851 properties in the front object.
5852
5853 Changed the toString behavior on the built-in object constructors
5854 to print [native code] instead of the actual source. Some web
5855 applications do not like constructors with complex toString
5856 results.

kasperl@chromium.org41044eb2008-10-06 08:24:46 +000058592008-10-06: Version 0.3.4
5860
5861 Changed Array.prototype.sort to use quick sort.
5862
5863 Fixed code generation issue where leaving a finally block with
5864 break or continue would accumulate elements on the expression
5865 stack (issue 86).
5866
5867 Made sure that the name accessor on functions returns the expected
5868 names for builtin JavaScript functions and C++ callback functions.
5869
5870 Added fast case code for extending the property storage array of
5871 JavaScript objects.
5872
5873 Ported switch statement optimizations introduced in version 0.3.3
5874 to the ARM code generator.
5875
5876 Allowed GCC to use strict-aliasing rules when compiling.
5877
5878 Improved performance of arguments object allocation by taking care
5879 of arguments adaptor frames in the generated code.
5880
5881 Updated the V8 benchmark suite to version 2.
5882
5883
ager@chromium.org236ad962008-09-25 09:45:57 +000058842008-09-25: Version 0.3.3
5885
5886 Improved handling of relocation information to enable more
5887 peep-hole optimizations.
5888
5889 Optimized switch statements where all labels are constant small
5890 integers.
5891
5892 Optimized String.prototype.indexOf for common cases.
5893
5894 Fixed more build issues (issue 80).
5895
5896 Fixed a couple of profiler issues.
5897
5898 Fixed bug where the body of a function created using the Function
5899 constructor was not allowed to end with a single-line comment
5900 (issue 85).
5901
5902 Improved handling of object literals by canonicalizing object
5903 literal maps. This will allow JSON objects with the same set of
5904 properties to share the same map making inline caching work better
5905 for JSON objects.

5909
5910 Generalized the EvalCache into a CompilationCache and enabled it
5911 for scripts too. The current strategy is to retire all entries
5912 whenever a mark-sweep collection is started.
5913
5914 Fixed bug where switch statements containing only a default case
5915 would lead to an unbalanced stack (issue 69).
5916
5917 Fixed bug that made access to the function in a named function
5918 expression impossible in certain situations (issue 24).
5919
5920 Fixed even more build issues.
5921
5922 Optimized calling conventions on ARM. The conventions on ARM and
5923 IA-32 now match.
5924
5925 Removed static initializers for flags and counters.
5926
5927 Improved inline caching behavior for uncommon cases where lazily
5928 loading Date and RegExp code could force certain code paths go
5929 megamorphic.
5930
5931 Removed arguments adaption for builtins written in C++. This
5932 makes Array.prototype.push and Array.prototype.pop slightly
5933 faster.
5934
5935
ager@chromium.org9258b6b2008-09-11 09:11:10 +000059362008-09-11: Version 0.3.1
5937
5938 Fixed a number of build issues.
5939
5940 Fixed problem with missing I-cache flusing on ARM.
5941
5942 Changed space layout in memory management by splitting up
5943 code space into old data space and code space.
5944
5945 Added utf-8 conversion support to the API (issue 57).
5946
5947 Optimized repeated calls to eval with the same strings. These
5948 repeated calls are common in web applications.
5949
5950 Added Xcode project file.
5951
5952 Optimized a couple of Array operation.
5953
5954 Fixed parser bug by checking for end-of-string when parsing break
5955 and continue (issue 35).
5956
5957 Fixed problem where asian characters were not categorized as
5958 letters.
5959
5960 Fixed bug that disallowed calling functions fetched from an array
5961 using a string as an array index (issue 32).
5962
5963 Fixed bug where the internal field count on object templates were
5964 sometimes ignored (issue 54).
5965
5966 Added -f option to the shell sample for compatibility with other
5967 engines (issue 18).
5968
5969 Added source info to TryCatches in the API.
5970
5971 Fixed problem where the seed for the random number generator was
5972 clipped in a double to unsigned int conversion.
5973
5974 Fixed bug where cons string symbols were sometimes converted to
5975 non-symbol flat strings during GC.
5976
5977 Fixed bug in error reporting when attempting to convert null to an
5978 object.

5982
5983 Added support for running tests on the ARM simulator.
5984
5985 Fixed bug in the 'in' operator where negative indices were not
5986 treated correctly.
5987
5988 Fixed build issues on gcc-4.3.1.
5989
5990 Changed Date.prototype.toLocaleTimeString to not print the
5991 timezone part of the time.
5992
5993 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
5994 with user code.
5995
5996
v8.team.kasperl727e9952008-09-02 14:56:44 +000059972008-09-02: Version 0.2.5
5998
5999 Renamed the top level directory 'public' to 'include'.
6000
6001 Added 'env' option to the SCons build scripts to support
6002 overriding the ENV part of the build environment. This is mostly
6003 to support Windows builds in cases where SCons cannot find the
6004 correct paths to the Windows SDK, as these paths cannot be passed
6005 through shell environment variables.
6006
6007 Enabled "Buffer Security Check" on for the Windows SCons build and
6008 added the linker option /OPT:ICF as an optimization.
6009
6010 Added the V8 benchmark suite to the repository.
6011
6012
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000060132008-09-01: Version 0.2.4
6014
6015 Included mjsunit JavaScript test suite and C++ unit tests.
6016
6017 Changed the shell sample to not print the result of executing a
6018 script provided on the command line.
6019
6020 Fixed issue when building samples on Windows using a shared V8
6021 library. Added visibility option on Linux build which makes the
6022 generated library 18% smaller.
6023
6024 Changed build system to accept multiple build modes in one build
6025 and generate separate objects, libraries and executables for each
6026 mode.
6027
6028 Removed deferred negation optimization (a * -b => -(a * b)) since
6029 this visibly changes operand conversion order.
6030
6031 Improved parsing performance by introducing stack guard in
6032 preparsing. Without a stack guard preparsing always bails out
6033 with stack overflow.
6034
6035 Changed shell sample to take flags directly from the command-line.
6036 Added API call that implements this.
6037
6038 Added load, quit and version functions to the shell sample so it's
6039 easier to run benchmarks and tests.
6040
6041 Fixed issue with building samples and cctests on 64-bit machines.
6042
6043 Fixed bug in the runtime system where the prototype chain was not
6044 always searched for a setter when setting a property that does not
6045 exist locally.

mads.s.agercbaa0602008-08-14 13:41:48 +000060482008-08-14: Version 0.2.3
6049
6050 Improved performance of garbage collection by moving the
6051 function that updates pointers during compacting collection
6052 into the updating visitor. This gives the compiler a better
6053 chance to inline and avoid a function call per (potential)
6054 pointer.
6055
6056 Extended the shell sample with a --runtime-flags option.
6057
6058 Added Visual Studio project files for the shell.cc and
6059 process.cc samples.
6060
6061
60622008-08-13: Version 0.2.2
mads.s.ager31e71382008-08-13 09:32:07 +00006063
6064 Improved performance of garbage collection by changing the way
6065 we use the marking stack in the event of stack overflow during
6066 full garbage collection and by changing the way we mark roots.
6067
6068 Cleaned up ARM version by removing top of stack caching and by
6069 introducing push/pop elimination.
6070
6071 Cleaned up the way runtime functions are called to allow
6072 runtime calls with no arguments.
6073
6074 Changed Windows build options to make sure that exceptions are
6075 disabled and that optimization flags are enabled.
6076
6077 Added first version of Visual Studio project files.
6078
6079

mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00006081
6082 Improved performance of unary addition by avoiding runtime calls.
6083
6084 Fixed the handling of '>' and '<=' to use right-to-left conversion
6085 and left-to-right evaluation as specified by ECMA-262.
6086
6087 Fixed a branch elimination bug on the ARM platform where incorrect
6088 code was generated because of overly aggressive branch
6089 elimination.
6090
6091 Improved performance of code that repeatedly assigns the same
6092 function to the same property of different objects with the same
6093 map.
6094
6095 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
6096 no longer expects DEBUG to be defined.
6097
6098 Added platform-nullos.cc to serve as the basis for new platform
6099 implementations.

kasper.lund7276f142008-07-30 08:49:36 +00006103
6104 Changed all text files to have native svn:eol-style.
6105
6106 Added a few samples and support for building them. The samples
6107 include a simple shell that can be used to benchmark and test V8.
6108
6109 Changed V8::GetVersion to return the version as a string.
6110
6111 Added source for lazily loaded scripts to snapshots and made
6112 serialization non-destructive.
6113
6114 Improved ARM support by fixing the write barrier code to use
6115 aligned loads and stores and by removing premature locals
6116 optimization that relied on broken support for callee-saved
6117 registers (removed).
6118
6119 Refactored the code for marking live objects during garbage
6120 collection and the code for allocating objects in paged
6121 spaces. Introduced an abstraction for the map word of a heap-
6122 allocated object and changed the memory allocator to allocate
6123 executable memory only for spaces that may contain code objects.
6124
6125 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
6126 they can be used by debugging and logging modules. Added
6127 thread-safe message queues for dealing with debugger events.
6128
6129 Fixed the source code reported by toString for certain builtin
6130 empty functions and made sure that the prototype property of a
6131 function is enumerable.
6132
6133 Improved performance of converting values to condition flags in
6134 generated code.
6135
6136 Merged disassembler-{arch} files.

kasper.lundaf4734f2008-07-28 12:50:18 +00006140
6141 Added support for storing JavaScript stack traces in a stack
6142 allocated buffer to make it visible in shallow core dumps.
6143 Controlled by the --preallocate-message-memory flag which is
6144 disabled by default.
6145
6146
mads.s.agercbaa0602008-08-14 13:41:48 +000061472008-07-25: Version 0.1.3
kasper.lund44510672008-07-25 07:37:58 +00006148
6149 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
6150 map transitions would count as properties.
6151
6152 Allowed aliased eval invocations by treating them as evals in the
6153 global context. This may change in the future.
6154
6155 Added support for accessing the last entered context through the
6156 API and renamed Context::Current to Context::GetCurrent and
6157 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
6158
6159 Fixed bug in the debugger that would cause the debugger scripts to
6160 be recursively loaded and changed all disabling of interrupts to
6161 be block-structured.
6162
6163 Made snapshot data read-only to allow it to be more easily shared
6164 across multiple users of V8 when linked as a shared library.
6165
6166
mads.s.agercbaa0602008-08-14 13:41:48 +000061672008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00006168
6169 Fixed building on Mac OS X by recognizing i386 and friends as
6170 IA-32 platforms.
6171
6172 Added propagation of stack overflow exceptions that occur while
6173 compiling nested functions.
6174
6175 Improved debugger with support for recursive break points and
6176 handling of exceptions that occur in the debugger JavaScript code.
6177
6178 Renamed GetInternal to GetInternalField and SetInternal to
6179 SetInternalField in the API and moved InternalFieldCount and
6180 SetInternalFieldCount from FunctionTemplate to ObjectTemplate.
6181
6182
mads.s.agercbaa0602008-08-14 13:41:48 +000061832008-07-09: Version 0.1.1
kasper.lundbd3ec4e2008-07-09 11:06:54 +00006184
6185 Fixed bug in stack overflow check code for IA-32 targets where a
6186 non-tagged value in register eax was pushed to the stack.
6187
6188 Fixed potential quadratic behavior when converting strings to
6189 numbers.
6190
6191 Fixed bug where the return value from Object::SetProperty could
6192 end up being the property holder instead of the written value.
6193
6194 Improved debugger support by allowing nested break points and by
6195 dealing with stack-overflows when compiling functions before
6196 setting break points in them.
6197
6198
