This 14136 makes Array.prototype.push and Array.prototype.pop slightly 14137 faster. 14138 14139 14140 2008-09-11: Version 0.3.1 14141 14142 Fixed a number of build issues. 14143 14144 Fixed problem with missing I-cache flusing on ARM. 14145 14146 Changed space layout in memory management by splitting up 14147 code space into old data space and code space. 14148 14149 Added utf-8 conversion support to the API (issue 57). 14150 14151 Optimized repeated calls to eval with the same strings. These 14152 repeated calls are common in web applications. 14153 14154 Added Xcode project file. 14155 14156 Optimized a couple of Array operation. 14157 14158 Fixed parser bug by checking for end-of-string when parsing break 14159 and continue (issue 35). 14160 14161 Fixed problem where asian characters were not categorized as 14162 letters. 14163 14164 Fixed bug that disallowed calling functions fetched from an array 14165 using a string as an array index (issue 32). 14166 14167 Fixed bug where the internal field count on object templates were 14168 sometimes ignored (issue 54). 14169 14170 Added -f option to the shell sample for compatibility with other 14171 engines (issue 18). 14172 14173 Added source info to TryCatches in the API. 14174 14175 Fixed problem where the seed for the random number generator was 14176 clipped in a double to unsigned int conversion. 14177 14178 Fixed bug where cons string symbols were sometimes converted to 14179 non-symbol flat strings during GC. 14180 14181 Fixed bug in error reporting when attempting to convert null to an 14182 object. 14183 14184 14185 2008-09-04: Version 0.3.0 14186 14187 Added support for running tests on the ARM simulator. 14188 14189 Fixed bug in the 'in' operator where negative indices were not 14190 treated correctly. 14191 14192 Fixed build issues on gcc-4.3.1. 14193 14194 Changed Date.prototype.toLocaleTimeString to not print the 14195 timezone part of the time. 14196 14197 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts 14198 with user code. 14199 14200 14201 2008-09-02: Version 0.2.5 14202 14203 Renamed the top level directory 'public' to 'include'. 14204 14205 Added 'env' option to the SCons build scripts to support 14206 overriding the ENV part of the build environment. This is mostly 14207 to support Windows builds in cases where SCons cannot find the 14208 correct paths to the Windows SDK, as these paths cannot be passed 14209 through shell environment variables. 14210 14211 Enabled "Buffer Security Check" on for the Windows SCons build and 14212 added the linker option /OPT:ICF as an optimization. 14213 14214 Added the V8 benchmark suite to the repository. 14215 14216 14217 2008-09-01: Version 0.2.4 14218 14219 Included mjsunit JavaScript test suite and C++ unit tests. 14220 14221 Changed the shell sample to not print the result of executing a 14222 script provided on the command line. 14223 14224 Fixed issue when building samples on Windows using a shared V8 14225 library. Added visibility option on Linux build which makes the 14226 generated library 18% smaller. 14227 14228 Changed build system to accept multiple build modes in one build 14229 and generate separate objects, libraries and executables for each 14230 mode. 14231 14232 Removed deferred negation optimization (a * -b => -(a * b)) since 14233 this visibly changes operand conversion order. 14234 14235 Improved parsing performance by introducing stack guard in 14236 preparsing. Without a stack guard preparsing always bails out 14237 with stack overflow. 14238 14239 Changed shell sample to take flags directly from the command-line. 14240 Added API call that implements this. 14241 14242 Added load, quit and version functions to the shell sample so it's 14243 easier to run benchmarks and tests. 14244 14245 Fixed issue with building samples and cctests on 64-bit machines. 14246 14247 Fixed bug in the runtime system where the prototype chain was not 14248 always searched for a setter when setting a property that does not 14249 exist locally. 14250 14251 14252 2008-08-14: Version 0.2.3 14253 14254 Improved performance of garbage collection by moving the 14255 function that updates pointers during compacting collection 14256 into the updating visitor. This gives the compiler a better 14257 chance to inline and avoid a function call per (potential) 14258 pointer. 14259 14260 Extended the shell sample with a --runtime-flags option. 14261 14262 Added Visual Studio project files for the shell.cc and 14263 process.cc samples. 14264 14265 14266 2008-08-13: Version 0.2.2 14267 14268 Improved performance of garbage collection by changing the way 14269 we use the marking stack in the event of stack overflow during 14270 full garbage collection and by changing the way we mark roots. 14271 14272 Cleaned up ARM version by removing top of stack caching and by 14273 introducing push/pop elimination. 14274 14275 Cleaned up the way runtime functions are called to allow 14276 runtime calls with no arguments. 14277 14278 Changed Windows build options to make sure that exceptions are 14279 disabled and that optimization flags are enabled. 14280 14281 Added first version of Visual Studio project files. 14282 14283 14284 2008-08-06: Version 0.2.1 14285 14286 Improved performance of unary addition by avoiding runtime calls. 14287 14288 Fixed the handling of '>' and '<=' to use right-to-left conversion 14289 and left-to-right evaluation as specified by ECMA-262. 14290 14291 Fixed a branch elimination bug on the ARM platform where incorrect 14292 code was generated because of overly aggressive branch 14293 elimination. 14294 14295 Improved performance of code that repeatedly assigns the same 14296 function to the same property of different objects with the same 14297 map. 14298 14299 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler 14300 no longer expects DEBUG to be defined. 14301 14302 Added platform-nullos.cc to serve as the basis for new platform 14303 implementations. 14304 14305 14306 2008-07-30: Version 0.2.0 14307 14308 Changed all text files to have native svn:eol-style. 14309 14310 Added a few samples and support for building them. The samples 14311 include a simple shell that can be used to benchmark and test V8. 14312 14313 Changed V8::GetVersion to return the version as a string. 14314 14315 Added source for lazily loaded scripts to snapshots and made 14316 serialization non-destructive. 14317 14318 Improved ARM support by fixing the write barrier code to use 14319 aligned loads and stores and by removing premature locals 14320 optimization that relied on broken support for callee-saved 14321 registers (removed). 14322 14323 Refactored the code for marking live objects during garbage 14324 collection and the code for allocating objects in paged 14325 spaces. Introduced an abstraction for the map word of a heap- 14326 allocated object and changed the memory allocator to allocate 14327 executable memory only for spaces that may contain code objects. 14328 14329 Moved StringBuilder to utils.h and ScopedLock to platform.h, where 14330 they can be used by debugging and logging modules. Added 14331 thread-safe message queues for dealing with debugger events. 14332 14333 Fixed the source code reported by toString for certain builtin 14334 empty functions and made sure that the prototype property of a 14335 function is enumerable. 14336 14337 Improved performance of converting values to condition flags in 14338 generated code. 14339 14340 Merged disassembler-{arch} files. 14341 14342 14343 2008-07-28: Version 0.1.4 14344 14345 Added support for storing JavaScript stack traces in a stack 14346 allocated buffer to make it visible in shallow core dumps. 14347 Controlled by the --preallocate-message-memory flag which is 14348 disabled by default. 14349 14350 14351 2008-07-25: Version 0.1.3 14352 14353 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where 14354 map transitions would count as properties. 14355 14356 Allowed aliased eval invocations by treating them as evals in the 14357 global context. This may change in the future. 14358 14359 Added support for accessing the last entered context through the 14360 API and renamed Context::Current to Context::GetCurrent and 14361 Context::GetSecurityContext to Context::GetCurrentSecurityContext. 14362 14363 Fixed bug in the debugger that would cause the debugger scripts to 14364 be recursively loaded and changed all disabling of interrupts to 14365 be block-structured. 14366 14367 Made snapshot data read-only to allow it to be more easily shared 14368 across multiple users of V8 when linked as a shared library. 14369 14370 14371 2008-07-16: Version 0.1.2 14372 14373 Fixed building on Mac OS X by recognizing i386 and friends as 14374 IA-32 platforms. 14375 14376 Added propagation of stack overflow exceptions that occur while 14377 compiling nested functions. 14378 14379 Improved debugger with support for recursive break points and 14380 handling of exceptions that occur in the debugger JavaScript code. 14381 14382 Renamed GetInternal to GetInternalField and SetInternal to 14383 SetInternalField in the API and moved InternalFieldCount and 14384 SetInternalFieldCount from FunctionTemplate to ObjectTemplate. 14385 14386 14387 2008-07-09: Version 0.1.1 14388 14389 Fixed bug in stack overflow check code for IA-32 targets where a 14390 non-tagged value in register eax was pushed to the stack. 14391 14392 Fixed potential quadratic behavior when converting strings to 14393 numbers. 14394 14395 Fixed bug where the return value from Object::SetProperty could 14396 end up being the property holder instead of the written value. 14397 14398 Improved debugger support by allowing nested break points and by 14399 dealing with stack-overflows when compiling functions before 14400 setting break points in them. 14401 14402 14403 2008-07-03: Version 0.1.0 14404 14405 Initial export. 14406 14407 # Local Variables: 14408 # mode:text 14409 # End: 14410
