3856
3857 Generalized the EvalCache into a CompilationCache and enabled it
3858 for scripts too. The current strategy is to retire all entries
3859 whenever a mark-sweep collection is started.
3860
3861 Fixed bug where switch statements containing only a default case
3862 would lead to an unbalanced stack (issue 69).
3863
3864 Fixed bug that made access to the function in a named function
3865 expression impossible in certain situations (issue 24).
3866
3867 Fixed even more build issues.
3868
3869 Optimized calling conventions on ARM. The conventions on ARM and
3870 IA-32 now match.
3871
3872 Removed static initializers for flags and counters.
3873
3874 Improved inline caching behavior for uncommon cases where lazily
3875 loading Date and RegExp code could force certain code paths go
3876 megamorphic.
3877
3878 Removed arguments adaption for builtins written in C++. This
3879 makes Array.prototype.push and Array.prototype.pop slightly
3880 faster.
3881
3882
ager@chromium.org9258b6b2008-09-11 09:11:10 +000038832008-09-11: Version 0.3.1
3884
3885 Fixed a number of build issues.
3886
3887 Fixed problem with missing I-cache flusing on ARM.
3888
3889 Changed space layout in memory management by splitting up
3890 code space into old data space and code space.
3891
3892 Added utf-8 conversion support to the API (issue 57).
3893
3894 Optimized repeated calls to eval with the same strings. These
3895 repeated calls are common in web applications.
3896
3897 Added Xcode project file.
3898
3899 Optimized a couple of Array operation.
3900
3901 Fixed parser bug by checking for end-of-string when parsing break
3902 and continue (issue 35).
3903
3904 Fixed problem where asian characters were not categorized as
3905 letters.
3906
3907 Fixed bug that disallowed calling functions fetched from an array
3908 using a string as an array index (issue 32).
3909
3910 Fixed bug where the internal field count on object templates were
3911 sometimes ignored (issue 54).
3912
3913 Added -f option to the shell sample for compatibility with other
3914 engines (issue 18).
3915
3916 Added source info to TryCatches in the API.
3917
3918 Fixed problem where the seed for the random number generator was
3919 clipped in a double to unsigned int conversion.
3920
3921 Fixed bug where cons string symbols were sometimes converted to
3922 non-symbol flat strings during GC.
3923
3924 Fixed bug in error reporting when attempting to convert null to an
3925 object.

ager@chromium.orgc27e4e72008-09-04 13:52:27 +000039282008-09-04: Version 0.3.0
3929
3930 Added support for running tests on the ARM simulator.
3931
3932 Fixed bug in the 'in' operator where negative indices were not
3933 treated correctly.
3934
3935 Fixed build issues on gcc-4.3.1.
3936
3937 Changed Date.prototype.toLocaleTimeString to not print the
3938 timezone part of the time.
3939
3940 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
3941 with user code.
3942
3943
v8.team.kasperl727e9952008-09-02 14:56:44 +000039442008-09-02: Version 0.2.5
3945
3946 Renamed the top level directory 'public' to 'include'.
3947
3948 Added 'env' option to the SCons build scripts to support
3949 overriding the ENV part of the build environment. This is mostly
3950 to support Windows builds in cases where SCons cannot find the
3951 correct paths to the Windows SDK, as these paths cannot be passed
3952 through shell environment variables.
3953
3954 Enabled "Buffer Security Check" on for the Windows SCons build and
3955 added the linker option /OPT:ICF as an optimization.
3956
3957 Added the V8 benchmark suite to the repository.
3958
3959
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000039602008-09-01: Version 0.2.4
3961
3962 Included mjsunit JavaScript test suite and C++ unit tests.
3963
3964 Changed the shell sample to not print the result of executing a
3965 script provided on the command line.
3966
3967 Fixed issue when building samples on Windows using a shared V8
3968 library. Added visibility option on Linux build which makes the
3969 generated library 18% smaller.
3970
3971 Changed build system to accept multiple build modes in one build
3972 and generate separate objects, libraries and executables for each
3973 mode.
3974
3975 Removed deferred negation optimization (a * -b => -(a * b)) since
3976 this visibly changes operand conversion order.
3977
3978 Improved parsing performance by introducing stack guard in
3979 preparsing. Without a stack guard preparsing always bails out
3980 with stack overflow.
3981
3982 Changed shell sample to take flags directly from the command-line.
3983 Added API call that implements this.
3984
3985 Added load, quit and version functions to the shell sample so it's
3986 easier to run benchmarks and tests.
3987
3988 Fixed issue with building samples and cctests on 64-bit machines.
3989
3990 Fixed bug in the runtime system where the prototype chain was not
3991 always searched for a setter when setting a property that does not
3992 exist locally.

mads.s.agercbaa0602008-08-14 13:41:48 +000039952008-08-14: Version 0.2.3
3996
3997 Improved performance of garbage collection by moving the
3998 function that updates pointers during compacting collection
3999 into the updating visitor. This gives the compiler a better
4000 chance to inline and avoid a function call per (potential)
4001 pointer.
4002
4003 Extended the shell sample with a --runtime-flags option.
4004
4005 Added Visual Studio project files for the shell.cc and
4006 process.cc samples.
4007
4008
40092008-08-13: Version 0.2.2
mads.s.ager31e71382008-08-13 09:32:07 +00004010
4011 Improved performance of garbage collection by changing the way
4012 we use the marking stack in the event of stack overflow during
4013 full garbage collection and by changing the way we mark roots.
4014
4015 Cleaned up ARM version by removing top of stack caching and by
4016 introducing push/pop elimination.
4017
4018 Cleaned up the way runtime functions are called to allow
4019 runtime calls with no arguments.
4020
4021 Changed Windows build options to make sure that exceptions are
4022 disabled and that optimization flags are enabled.
4023
4024 Added first version of Visual Studio project files.
4025
4026
mads.s.agercbaa0602008-08-14 13:41:48 +000040272008-08-06: Version 0.2.1
mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00004028
4029 Improved performance of unary addition by avoiding runtime calls.
4030
4031 Fixed the handling of '>' and '<=' to use right-to-left conversion
4032 and left-to-right evaluation as specified by ECMA-262.
4033
4034 Fixed a branch elimination bug on the ARM platform where incorrect
4035 code was generated because of overly aggressive branch
4036 elimination.
4037
4038 Improved performance of code that repeatedly assigns the same
4039 function to the same property of different objects with the same
4040 map.
4041
4042 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
4043 no longer expects DEBUG to be defined.
4044
4045 Added platform-nullos.cc to serve as the basis for new platform
4046 implementations.
4047

kasper.lund7276f142008-07-30 08:49:36 +00004050
4051 Changed all text files to have native svn:eol-style.
4052
4053 Added a few samples and support for building them. The samples
4054 include a simple shell that can be used to benchmark and test V8.
4055
4056 Changed V8::GetVersion to return the version as a string.
4057
4058 Added source for lazily loaded scripts to snapshots and made
4059 serialization non-destructive.
4060
4061 Improved ARM support by fixing the write barrier code to use
4062 aligned loads and stores and by removing premature locals
4063 optimization that relied on broken support for callee-saved
4064 registers (removed).
4065
4066 Refactored the code for marking live objects during garbage
4067 collection and the code for allocating objects in paged
4068 spaces. Introduced an abstraction for the map word of a heap-
4069 allocated object and changed the memory allocator to allocate
4070 executable memory only for spaces that may contain code objects.
4071
4072 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
4073 they can be used by debugging and logging modules. Added
4074 thread-safe message queues for dealing with debugger events.
4075
4076 Fixed the source code reported by toString for certain builtin
4077 empty functions and made sure that the prototype property of a
4078 function is enumerable.
4079
4080 Improved performance of converting values to condition flags in
4081 generated code.
4082
4083 Merged disassembler-{arch} files.
4084
4085
mads.s.agercbaa0602008-08-14 13:41:48 +000040862008-07-28: Version 0.1.4
kasper.lundaf4734f2008-07-28 12:50:18 +00004087
4088 Added support for storing JavaScript stack traces in a stack
4089 allocated buffer to make it visible in shallow core dumps.
4090 Controlled by the --preallocate-message-memory flag which is
4091 disabled by default.
4092
4093
mads.s.agercbaa0602008-08-14 13:41:48 +000040942008-07-25: Version 0.1.3
kasper.lund44510672008-07-25 07:37:58 +00004095
4096 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
4097 map transitions would count as properties.
4098
4099 Allowed aliased eval invocations by treating them as evals in the
4100 global context. This may change in the future.
4101
4102 Added support for accessing the last entered context through the
4103 API and renamed Context::Current to Context::GetCurrent and
4104 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
4105
4106 Fixed bug in the debugger that would cause the debugger scripts to
4107 be recursively loaded and changed all disabling of interrupts to
4108 be block-structured.
4109
4110 Made snapshot data read-only to allow it to be more easily shared
4111 across multiple users of V8 when linked as a shared library.
4112
4113
mads.s.agercbaa0602008-08-14 13:41:48 +000041142008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00004115
4116 Fixed building on Mac OS X by recognizing i386 and friends as
4117 IA-32 platforms.
4118
4119 Added propagation of stack overflow exceptions that occur while
4120 compiling nested functions.
4121
4122 Improved debugger with support for recursive break points and
4123 handling of exceptions that occur in the debugger JavaScript code.
4124
4125 Renamed GetInternal to GetInternalField and SetInternal to
4126 SetInternalField in the API and moved InternalFieldCount and
4127 SetInternalFieldCount from FunctionTemplate to ObjectTemplate.
4128
4129
mads.s.agercbaa0602008-08-14 13:41:48 +000041302008-07-09: Version 0.1.1
kasper.lundbd3ec4e2008-07-09 11:06:54 +00004131
4132 Fixed bug in stack overflow check code for IA-32 targets where a
4133 non-tagged value in register eax was pushed to the stack.
4134
4135 Fixed potential quadratic behavior when converting strings to
4136 numbers.
4137
4138 Fixed bug where the return value from Object::SetProperty could
4139 end up being the property holder instead of the written value.
4140
4141 Improved debugger support by allowing nested break points and by
4142 dealing with stack-overflows when compiling functions before
4143 setting break points in them.
4144
4145
