This is mostly 8123 to support Windows builds in cases where SCons cannot find the 8124 correct paths to the Windows SDK, as these paths cannot be passed 8125 through shell environment variables. 8126 8127 Enabled "Buffer Security Check" on for the Windows SCons build and 8128 added the linker option /OPT:ICF as an optimization. 8129 8130 Added the V8 benchmark suite to the repository. 8131 8132 8133 2008-09-01: Version 0.2.4 8134 8135 Included mjsunit JavaScript test suite and C++ unit tests. 8136 8137 Changed the shell sample to not print the result of executing a 8138 script provided on the command line. 8139 8140 Fixed issue when building samples on Windows using a shared V8 8141 library. Added visibility option on Linux build which makes the 8142 generated library 18% smaller. 8143 8144 Changed build system to accept multiple build modes in one build 8145 and generate separate objects, libraries and executables for each 8146 mode. 8147 8148 Removed deferred negation optimization (a * -b => -(a * b)) since 8149 this visibly changes operand conversion order. 8150 8151 Improved parsing performance by introducing stack guard in 8152 preparsing. Without a stack guard preparsing always bails out 8153 with stack overflow. 8154 8155 Changed shell sample to take flags directly from the command-line. 8156 Added API call that implements this. 8157 8158 Added load, quit and version functions to the shell sample so it's 8159 easier to run benchmarks and tests. 8160 8161 Fixed issue with building samples and cctests on 64-bit machines. 8162 8163 Fixed bug in the runtime system where the prototype chain was not 8164 always searched for a setter when setting a property that does not 8165 exist locally. 8166 8167 8168 2008-08-14: Version 0.2.3 8169 8170 Improved performance of garbage collection by moving the 8171 function that updates pointers during compacting collection 8172 into the updating visitor. This gives the compiler a better 8173 chance to inline and avoid a function call per (potential) 8174 pointer. 8175 8176 Extended the shell sample with a --runtime-flags option. 8177 8178 Added Visual Studio project files for the shell.cc and 8179 process.cc samples. 8180 8181 8182 2008-08-13: Version 0.2.2 8183 8184 Improved performance of garbage collection by changing the way 8185 we use the marking stack in the event of stack overflow during 8186 full garbage collection and by changing the way we mark roots. 8187 8188 Cleaned up ARM version by removing top of stack caching and by 8189 introducing push/pop elimination. 8190 8191 Cleaned up the way runtime functions are called to allow 8192 runtime calls with no arguments. 8193 8194 Changed Windows build options to make sure that exceptions are 8195 disabled and that optimization flags are enabled. 8196 8197 Added first version of Visual Studio project files. 8198 8199 8200 2008-08-06: Version 0.2.1 8201 8202 Improved performance of unary addition by avoiding runtime calls. 8203 8204 Fixed the handling of '>' and '<=' to use right-to-left conversion 8205 and left-to-right evaluation as specified by ECMA-262. 8206 8207 Fixed a branch elimination bug on the ARM platform where incorrect 8208 code was generated because of overly aggressive branch 8209 elimination. 8210 8211 Improved performance of code that repeatedly assigns the same 8212 function to the same property of different objects with the same 8213 map. 8214 8215 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler 8216 no longer expects DEBUG to be defined. 8217 8218 Added platform-nullos.cc to serve as the basis for new platform 8219 implementations. 8220 8221 8222 2008-07-30: Version 0.2.0 8223 8224 Changed all text files to have native svn:eol-style. 8225 8226 Added a few samples and support for building them. The samples 8227 include a simple shell that can be used to benchmark and test V8. 8228 8229 Changed V8::GetVersion to return the version as a string. 8230 8231 Added source for lazily loaded scripts to snapshots and made 8232 serialization non-destructive. 8233 8234 Improved ARM support by fixing the write barrier code to use 8235 aligned loads and stores and by removing premature locals 8236 optimization that relied on broken support for callee-saved 8237 registers (removed). 8238 8239 Refactored the code for marking live objects during garbage 8240 collection and the code for allocating objects in paged 8241 spaces. Introduced an abstraction for the map word of a heap- 8242 allocated object and changed the memory allocator to allocate 8243 executable memory only for spaces that may contain code objects. 8244 8245 Moved StringBuilder to utils.h and ScopedLock to platform.h, where 8246 they can be used by debugging and logging modules. Added 8247 thread-safe message queues for dealing with debugger events. 8248 8249 Fixed the source code reported by toString for certain builtin 8250 empty functions and made sure that the prototype property of a 8251 function is enumerable. 8252 8253 Improved performance of converting values to condition flags in 8254 generated code. 8255 8256 Merged disassembler-{arch} files. 8257 8258 8259 2008-07-28: Version 0.1.4 8260 8261 Added support for storing JavaScript stack traces in a stack 8262 allocated buffer to make it visible in shallow core dumps. 8263 Controlled by the --preallocate-message-memory flag which is 8264 disabled by default. 8265 8266 8267 2008-07-25: Version 0.1.3 8268 8269 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where 8270 map transitions would count as properties. 8271 8272 Allowed aliased eval invocations by treating them as evals in the 8273 global context. This may change in the future. 8274 8275 Added support for accessing the last entered context through the 8276 API and renamed Context::Current to Context::GetCurrent and 8277 Context::GetSecurityContext to Context::GetCurrentSecurityContext. 8278 8279 Fixed bug in the debugger that would cause the debugger scripts to 8280 be recursively loaded and changed all disabling of interrupts to 8281 be block-structured. 8282 8283 Made snapshot data read-only to allow it to be more easily shared 8284 across multiple users of V8 when linked as a shared library. 8285 8286 8287 2008-07-16: Version 0.1.2 8288 8289 Fixed building on Mac OS X by recognizing i386 and friends as 8290 IA-32 platforms. 8291 8292 Added propagation of stack overflow exceptions that occur while 8293 compiling nested functions. 8294 8295 Improved debugger with support for recursive break points and 8296 handling of exceptions that occur in the debugger JavaScript code. 8297 8298 Renamed GetInternal to GetInternalField and SetInternal to 8299 SetInternalField in the API and moved InternalFieldCount and 8300 SetInternalFieldCount from FunctionTemplate to ObjectTemplate. 8301 8302 8303 2008-07-09: Version 0.1.1 8304 8305 Fixed bug in stack overflow check code for IA-32 targets where a 8306 non-tagged value in register eax was pushed to the stack. 8307 8308 Fixed potential quadratic behavior when converting strings to 8309 numbers. 8310 8311 Fixed bug where the return value from Object::SetProperty could 8312 end up being the property holder instead of the written value. 8313 8314 Improved debugger support by allowing nested break points and by 8315 dealing with stack-overflows when compiling functions before 8316 setting break points in them. 8317 8318 8319 2008-07-03: Version 0.1.0 8320 8321 Initial export. 8322 8323 # Local Variables: 8324 # mode:text 8325 # End: 8326
