| |
| Changed Array.prototype.sort to use quick sort. |
| |

| for JSON objects. |
| |
| |
| 2008-09-17: Version 0.3.2 |
| |
| Generalized the EvalCache into a CompilationCache and enabled it |

| whenever a mark-sweep collection is started. |
| |
| Fixed bug where switch statements containing only a default case |

| |
| Fixed bug that made access to the function in a named function |

| loading Date and RegExp code could force certain code paths go |
| megamorphic. |
| |
| Removed arguments adaption for builtins written in C++. This |
| makes Array.prototype.push and Array.prototype.pop slightly |
| faster. |
| |
| |

| |
| Fixed a number of build issues. |

| code space into old data space and code space. |
| |

| sometimes ignored (issue 54). |
| |

| |
| Changed Date.prototype.toLocaleTimeString to not print the |
| timezone part of the time. |
| |
| Renamed debug.h to v8-debug.h to reduce the risk of name conflicts |
| with user code. |
| |
| |
| 2008-09-02: Version 0.2.5 |
| |
| Renamed the top level directory 'public' to 'include'. |
| |
| Added 'env' option to the SCons build scripts to support |
| overriding the ENV part of the build environment. This is mostly |
| to support Windows builds in cases where SCons cannot find the |
| correct paths to the Windows SDK, as these paths cannot be passed |
| through shell environment variables. |
| |
| Enabled "Buffer Security Check" on for the Windows SCons build and |
| added the linker option /OPT:ICF as an optimization. |
| |
| Added the V8 benchmark suite to the repository. |
| |
| |

| script provided on the command line. |
| |
| Fixed issue when building samples on Windows using a shared V8 |
| library. Added visibility option on Linux build which makes the |
| generated library 18% smaller. |
| |
| Changed build system to accept multiple build modes in one build |
| and generate separate objects, libraries and executables for each |
| mode. |
| |
| Removed deferred negation optimization (a * -b => -(a * b)) since |
| this visibly changes operand conversion order. |
| |
| Improved parsing performance by introducing stack guard in |
| preparsing. Without a stack guard preparsing always bails out |
| with stack overflow. |
| |
| Changed shell sample to take flags directly from the command-line. |
| Added API call that implements this. |
| |
| Added load, quit and version functions to the shell sample so it's |
| easier to run benchmarks and tests. |
| |
| Fixed issue with building samples and cctests on 64-bit machines. |
| |
| Fixed bug in the runtime system where the prototype chain was not |
| always searched for a setter when setting a property that does not |
| exist locally. |
| |
| |
| 2008-08-14: Version 0.2.3 |
| |
| Improved performance of garbage collection by moving the |
| function that updates pointers during compacting collection |
| into the updating visitor. This gives the compiler a better |
| chance to inline and avoid a function call per (potential) |
| pointer. |
| |
| Extended the shell sample with a --runtime-flags option. |
| |
| Added Visual Studio project files for the shell.cc and |
| process.cc samples. |
| |
| |
| 2008-08-13: Version 0.2.2 |
| |
| Improved performance of garbage collection by changing the way |
| we use the marking stack in the event of stack overflow during |
| full garbage collection and by changing the way we mark roots. |
| |

| introducing push/pop elimination. |
| |
| Cleaned up the way runtime functions are called to allow |
| runtime calls with no arguments. |

| disabled and that optimization flags are enabled. |
| |

| |
| |
| 2008-08-06: Version 0.2.1 |
| |
| Improved performance of unary addition by avoiding runtime calls. |

| Fixed the handling of '>' and '<=' to use right-to-left conversion |
| and left-to-right evaluation as specified by ECMA-262. |
| |
| Fixed a branch elimination bug on the ARM platform where incorrect |
| code was generated because of overly aggressive branch |
| elimination. |
| |
| Improved performance of code that repeatedly assigns the same |
| function to the same property of different objects with the same |
| map. |
| |
| Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| no longer expects DEBUG to be defined. |
| |
| Added platform-nullos.cc to serve as the basis for new platform |
| implementations. |
| |
| |
| 2008-07-30: Version 0.2.0 |
| |
| Changed all text files to have native svn:eol-style. |
| |
| Added a few samples and support for building them. The samples |
| include a simple shell that can be used to benchmark and test V8. |
| |
| Changed V8::GetVersion to return the version as a string. |
| |
| Added source for lazily loaded scripts to snapshots and made |
| serialization non-destructive. |
| |
| Improved ARM support by fixing the write barrier code to use |
| aligned loads and stores and by removing premature locals |
| optimization that relied on broken support for callee-saved |
| registers (removed). |
| |
| Refactored the code for marking live objects during garbage |
| collection and the code for allocating objects in paged |
| spaces. Introduced an abstraction for the map word of a heap- |
| allocated object and changed the memory allocator to allocate |
| executable memory only for spaces that may contain code objects. |
| |
| Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| they can be used by debugging and logging modules. Added |
| thread-safe message queues for dealing with debugger events. |
| |
| Fixed the source code reported by toString for certain builtin |
| empty functions and made sure that the prototype property of a |
| function is enumerable. |
| |
| Improved performance of converting values to condition flags in |
| generated code. |
| |
| Merged disassembler-{arch} files. |
| |
| |
| 2008-07-28: Version 0.1.4 |
| |
| Added support for storing JavaScript stack traces in a stack |
| allocated buffer to make it visible in shallow core dumps. |
| Controlled by the --preallocate-message-memory flag which is |
| disabled by default. |
| |
| |
| 2008-07-25: Version 0.1.3 |
| |
| Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| map transitions would count as properties. |
| |
| Allowed aliased eval invocations by treating them as evals in the |
| global context. This may change in the future. |
| |
| Added support for accessing the last entered context through the |
| API and renamed Context::Current to Context::GetCurrent and |
| Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| |
| Fixed bug in the debugger that would cause the debugger scripts to |
| be recursively loaded and changed all disabling of interrupts to |
| be block-structured. |
| |
| Made snapshot data read-only to allow it to be more easily shared |
| across multiple users of V8 when linked as a shared library. |
| |
| |
| 2008-07-16: Version 0.1.2 |
| |
| Fixed building on Mac OS X by recognizing i386 and friends as |
| IA-32 platforms. |
| |
| Added propagation of stack overflow exceptions that occur while |
| compiling nested functions. |
| |
| Improved debugger with support for recursive break points and |
| handling of exceptions that occur in the debugger JavaScript code. |
| |
| Renamed GetInternal to GetInternalField and SetInternal to |
| SetInternalField in the API and moved InternalFieldCount and |
| SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
| |
| |
| 2008-07-09: Version 0.1.1 |
| |
| Fixed bug in stack overflow check code for IA-32 targets where a |
| non-tagged value in register eax was pushed to the stack. |
| |
| Fixed potential quadratic behavior when converting strings to |
| numbers. |
| |
| Fixed bug where the return value from Object::SetProperty could |
| end up being the property holder instead of the written value. |
| |
| Improved debugger support by allowing nested break points and by |
| dealing with stack-overflows when compiling functions before |
| setting break points in them. |
| |
| |
| 2008-07-03: Version 0.1.0 |
| |
| Initial export. |
