v8.team.kasperl | 727e995 | 2008-09-02 14:56:44 +0000 | [diff] [blame^] | 1 | 2008-09-02: Version 0.2.5 |
| 2 | |
| 3 | Renamed the top level directory 'public' to 'include'. |
| 4 | |
| 5 | Added 'env' option to the SCons build scripts to support |
| 6 | overriding the ENV part of the build environment. This is mostly |
| 7 | to support Windows builds in cases where SCons cannot find the |
| 8 | correct paths to the Windows SDK, as these paths cannot be passed |
| 9 | through shell environment variables. |
| 10 | |
| 11 | Enabled "Buffer Security Check" on for the Windows SCons build and |
| 12 | added the linker option /OPT:ICF as an optimization. |
| 13 | |
| 14 | Added the V8 benchmark suite to the repository. |
| 15 | |

| 18 | |
| 19 | Included mjsunit JavaScript test suite and C++ unit tests. |
| 20 | |
| 21 | Changed the shell sample to not print the result of executing a |
| 22 | script provided on the command line. |
| 23 | |
| 24 | Fixed issue when building samples on Windows using a shared V8 |
| 25 | library. Added visibility option on Linux build which makes the |
| 26 | generated library 18% smaller. |
| 27 | |
| 28 | Changed build system to accept multiple build modes in one build |
| 29 | and generate separate objects, libraries and executables for each |
| 30 | mode. |
| 31 | |
| 32 | Removed deferred negation optimization (a * -b => -(a * b)) since |
| 33 | this visibly changes operand conversion order. |
| 34 | |
| 35 | Improved parsing performance by introducing stack guard in |
| 36 | preparsing. Without a stack guard preparsing always bails out |
| 37 | with stack overflow. |
| 38 | |
| 39 | Changed shell sample to take flags directly from the command-line. |
| 40 | Added API call that implements this. |
| 41 | |
| 42 | Added load, quit and version functions to the shell sample so it's |
| 43 | easier to run benchmarks and tests. |
| 44 | |
| 45 | Fixed issue with building samples and cctests on 64-bit machines. |
| 46 | |
| 47 | Fixed bug in the runtime system where the prototype chain was not |
| 48 | always searched for a setter when setting a property that does not |
| 49 | exist locally. |
| 50 | |
| 51 | |
mads.s.ager | cbaa060 | 2008-08-14 13:41:48 +0000 | [diff] [blame] | 52 | 2008-08-14: Version 0.2.3 |
| 53 | |
| 54 | Improved performance of garbage collection by moving the |
| 55 | function that updates pointers during compacting collection |
| 56 | into the updating visitor. This gives the compiler a better |
| 57 | chance to inline and avoid a function call per (potential) |
| 58 | pointer. |
| 59 | |
| 60 | Extended the shell sample with a --runtime-flags option. |
| 61 | |
| 62 | Added Visual Studio project files for the shell.cc and |
| 63 | process.cc samples. |
| 64 | |
| 65 | |
| 66 | 2008-08-13: Version 0.2.2 |
mads.s.ager | 31e7138 | 2008-08-13 09:32:07 +0000 | [diff] [blame] | 67 | |
| 68 | Improved performance of garbage collection by changing the way |
| 69 | we use the marking stack in the event of stack overflow during |
| 70 | full garbage collection and by changing the way we mark roots. |
| 71 | |
| 72 | Cleaned up ARM version by removing top of stack caching and by |
| 73 | introducing push/pop elimination. |
| 74 | |
| 75 | Cleaned up the way runtime functions are called to allow |
| 76 | runtime calls with no arguments. |
| 77 | |
| 78 | Changed Windows build options to make sure that exceptions are |
| 79 | disabled and that optimization flags are enabled. |
| 80 | |
| 81 | Added first version of Visual Studio project files. |
| 82 | |

mads.s.ager@gmail.com | 769cc96 | 2008-08-06 10:02:49 +0000 | [diff] [blame] | 85 | |
| 86 | Improved performance of unary addition by avoiding runtime calls. |
| 87 | |
| 88 | Fixed the handling of '>' and '<=' to use right-to-left conversion |
| 89 | and left-to-right evaluation as specified by ECMA-262. |
| 90 | |
| 91 | Fixed a branch elimination bug on the ARM platform where incorrect |
| 92 | code was generated because of overly aggressive branch |
| 93 | elimination. |
| 94 | |
| 95 | Improved performance of code that repeatedly assigns the same |
| 96 | function to the same property of different objects with the same |
| 97 | map. |
| 98 | |
| 99 | Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| 100 | no longer expects DEBUG to be defined. |
| 101 | |
| 102 | Added platform-nullos.cc to serve as the basis for new platform |
| 103 | implementations. |
| 104 | |

kasper.lund | 7276f14 | 2008-07-30 08:49:36 +0000 | [diff] [blame] | 107 | |
| 108 | Changed all text files to have native svn:eol-style. |
| 109 | |
| 110 | Added a few samples and support for building them. The samples |
| 111 | include a simple shell that can be used to benchmark and test V8. |
| 112 | |
| 113 | Changed V8::GetVersion to return the version as a string. |
| 114 | |
| 115 | Added source for lazily loaded scripts to snapshots and made |
| 116 | serialization non-destructive. |
| 117 | |
| 118 | Improved ARM support by fixing the write barrier code to use |
| 119 | aligned loads and stores and by removing premature locals |
| 120 | optimization that relied on broken support for callee-saved |
| 121 | registers (removed). |
| 122 | |
| 123 | Refactored the code for marking live objects during garbage |
| 124 | collection and the code for allocating objects in paged |
| 125 | spaces. Introduced an abstraction for the map word of a heap- |
| 126 | allocated object and changed the memory allocator to allocate |
| 127 | executable memory only for spaces that may contain code objects. |
| 128 | |
| 129 | Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| 130 | they can be used by debugging and logging modules. Added |
| 131 | thread-safe message queues for dealing with debugger events. |
| 132 | |
| 133 | Fixed the source code reported by toString for certain builtin |
| 134 | empty functions and made sure that the prototype property of a |
| 135 | function is enumerable. |
| 136 | |
| 137 | Improved performance of converting values to condition flags in |
| 138 | generated code. |
| 139 | |
| 140 | Merged disassembler-{arch} files. |
| 141 | |
| 142 | |

kasper.lund | af4734f | 2008-07-28 12:50:18 +0000 | [diff] [blame] | 144 | |
| 145 | Added support for storing JavaScript stack traces in a stack |
| 146 | allocated buffer to make it visible in shallow core dumps. |
| 147 | Controlled by the --preallocate-message-memory flag which is |
| 148 | disabled by default. |
| 149 | |
| 150 | |
mads.s.ager | cbaa060 | 2008-08-14 13:41:48 +0000 | [diff] [blame] | 151 | 2008-07-25: Version 0.1.3 |
kasper.lund | 4451067 | 2008-07-25 07:37:58 +0000 | [diff] [blame] | 152 | |
| 153 | Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| 154 | map transitions would count as properties. |
| 155 | |
| 156 | Allowed aliased eval invocations by treating them as evals in the |
| 157 | global context. This may change in the future. |
| 158 | |
| 159 | Added support for accessing the last entered context through the |
| 160 | API and renamed Context::Current to Context::GetCurrent and |
| 161 | Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| 162 | |
| 163 | Fixed bug in the debugger that would cause the debugger scripts to |
| 164 | be recursively loaded and changed all disabling of interrupts to |
| 165 | be block-structured. |
| 166 | |
| 167 | Made snapshot data read-only to allow it to be more easily shared |
| 168 | across multiple users of V8 when linked as a shared library. |
| 169 | |
| 170 | |

kasper.lund | 212ac23 | 2008-07-16 07:07:30 +0000 | [diff] [blame] | 172 | |
| 173 | Fixed building on Mac OS X by recognizing i386 and friends as |
| 174 | IA-32 platforms. |
| 175 | |
| 176 | Added propagation of stack overflow exceptions that occur while |
| 177 | compiling nested functions. |
| 178 | |
| 179 | Improved debugger with support for recursive break points and |
| 180 | handling of exceptions that occur in the debugger JavaScript code. |
| 181 | |
| 182 | Renamed GetInternal to GetInternalField and SetInternal to |
| 183 | SetInternalField in the API and moved InternalFieldCount and |
| 184 | SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
| 185 | |
| 186 | |

kasper.lund | bd3ec4e | 2008-07-09 11:06:54 +0000 | [diff] [blame] | 188 | |
| 189 | Fixed bug in stack overflow check code for IA-32 targets where a |
| 190 | non-tagged value in register eax was pushed to the stack. |
| 191 | |
| 192 | Fixed potential quadratic behavior when converting strings to |
| 193 | numbers. |
| 194 | |
| 195 | Fixed bug where the return value from Object::SetProperty could |
| 196 | end up being the property holder instead of the written value. |
| 197 | |
| 198 | Improved debugger support by allowing nested break points and by |
| 199 | dealing with stack-overflows when compiling functions before |
| 200 | setting break points in them. |
| 201 | |
