This is mostly 7454 to support Windows builds in cases where SCons cannot find the 7455 correct paths to the Windows SDK, as these paths cannot be passed 7456 through shell environment variables. 7457 7458 Enabled "Buffer Security Check" on for the Windows SCons build and 7459 added the linker option /OPT:ICF as an optimization. 7460 7461 Added the V8 benchmark suite to the repository. 7462 7463 7464 2008-09-01: Version 0.2.4 7465 7466 Included mjsunit JavaScript test suite and C++ unit tests. 7467 7468 Changed the shell sample to not print the result of executing a 7469 script provided on the command line. 7470 7471 Fixed issue when building samples on Windows using a shared V8 7472 library. Added visibility option on Linux build which makes the 7473 generated library 18% smaller. 7474 7475 Changed build system to accept multiple build modes in one build 7476 and generate separate objects, libraries and executables for each 7477 mode. 7478 7479 Removed deferred negation optimization (a * -b => -(a * b)) since 7480 this visibly changes operand conversion order. 7481 7482 Improved parsing performance by introducing stack guard in 7483 preparsing. Without a stack guard preparsing always bails out 7484 with stack overflow. 7485 7486 Changed shell sample to take flags directly from the command-line. 7487 Added API call that implements this. 7488 7489 Added load, quit and version functions to the shell sample so it's 7490 easier to run benchmarks and tests. 7491 7492 Fixed issue with building samples and cctests on 64-bit machines. 7493 7494 Fixed bug in the runtime system where the prototype chain was not 7495 always searched for a setter when setting a property that does not 7496 exist locally. 7497 7498 7499 2008-08-14: Version 0.2.3 7500 7501 Improved performance of garbage collection by moving the 7502 function that updates pointers during compacting collection 7503 into the updating visitor. This gives the compiler a better 7504 chance to inline and avoid a function call per (potential) 7505 pointer. 7506 7507 Extended the shell sample with a --runtime-flags option. 7508 7509 Added Visual Studio project files for the shell.cc and 7510 process.cc samples. 7511 7512 7513 2008-08-13: Version 0.2.2 7514 7515 Improved performance of garbage collection by changing the way 7516 we use the marking stack in the event of stack overflow during 7517 full garbage collection and by changing the way we mark roots. 7518 7519 Cleaned up ARM version by removing top of stack caching and by 7520 introducing push/pop elimination. 7521 7522 Cleaned up the way runtime functions are called to allow 7523 runtime calls with no arguments. 7524 7525 Changed Windows build options to make sure that exceptions are 7526 disabled and that optimization flags are enabled. 7527 7528 Added first version of Visual Studio project files. 7529 7530 7531 2008-08-06: Version 0.2.1 7532 7533 Improved performance of unary addition by avoiding runtime calls. 7534 7535 Fixed the handling of '>' and '<=' to use right-to-left conversion 7536 and left-to-right evaluation as specified by ECMA-262. 7537 7538 Fixed a branch elimination bug on the ARM platform where incorrect 7539 code was generated because of overly aggressive branch 7540 elimination. 7541 7542 Improved performance of code that repeatedly assigns the same 7543 function to the same property of different objects with the same 7544 map. 7545 7546 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler 7547 no longer expects DEBUG to be defined. 7548 7549 Added platform-nullos.cc to serve as the basis for new platform 7550 implementations. 7551 7552 7553 2008-07-30: Version 0.2.0 7554 7555 Changed all text files to have native svn:eol-style. 7556 7557 Added a few samples and support for building them. The samples 7558 include a simple shell that can be used to benchmark and test V8. 7559 7560 Changed V8::GetVersion to return the version as a string. 7561 7562 Added source for lazily loaded scripts to snapshots and made 7563 serialization non-destructive. 7564 7565 Improved ARM support by fixing the write barrier code to use 7566 aligned loads and stores and by removing premature locals 7567 optimization that relied on broken support for callee-saved 7568 registers (removed). 7569 7570 Refactored the code for marking live objects during garbage 7571 collection and the code for allocating objects in paged 7572 spaces. Introduced an abstraction for the map word of a heap- 7573 allocated object and changed the memory allocator to allocate 7574 executable memory only for spaces that may contain code objects. 7575 7576 Moved StringBuilder to utils.h and ScopedLock to platform.h, where 7577 they can be used by debugging and logging modules. Added 7578 thread-safe message queues for dealing with debugger events. 7579 7580 Fixed the source code reported by toString for certain builtin 7581 empty functions and made sure that the prototype property of a 7582 function is enumerable. 7583 7584 Improved performance of converting values to condition flags in 7585 generated code. 7586 7587 Merged disassembler-{arch} files. 7588 7589 7590 2008-07-28: Version 0.1.4 7591 7592 Added support for storing JavaScript stack traces in a stack 7593 allocated buffer to make it visible in shallow core dumps. 7594 Controlled by the --preallocate-message-memory flag which is 7595 disabled by default. 7596 7597 7598 2008-07-25: Version 0.1.3 7599 7600 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where 7601 map transitions would count as properties. 7602 7603 Allowed aliased eval invocations by treating them as evals in the 7604 global context. This may change in the future. 7605 7606 Added support for accessing the last entered context through the 7607 API and renamed Context::Current to Context::GetCurrent and 7608 Context::GetSecurityContext to Context::GetCurrentSecurityContext. 7609 7610 Fixed bug in the debugger that would cause the debugger scripts to 7611 be recursively loaded and changed all disabling of interrupts to 7612 be block-structured. 7613 7614 Made snapshot data read-only to allow it to be more easily shared 7615 across multiple users of V8 when linked as a shared library. 7616 7617 7618 2008-07-16: Version 0.1.2 7619 7620 Fixed building on Mac OS X by recognizing i386 and friends as 7621 IA-32 platforms. 7622 7623 Added propagation of stack overflow exceptions that occur while 7624 compiling nested functions. 7625 7626 Improved debugger with support for recursive break points and 7627 handling of exceptions that occur in the debugger JavaScript code. 7628 7629 Renamed GetInternal to GetInternalField and SetInternal to 7630 SetInternalField in the API and moved InternalFieldCount and 7631 SetInternalFieldCount from FunctionTemplate to ObjectTemplate. 7632 7633 7634 2008-07-09: Version 0.1.1 7635 7636 Fixed bug in stack overflow check code for IA-32 targets where a 7637 non-tagged value in register eax was pushed to the stack. 7638 7639 Fixed potential quadratic behavior when converting strings to 7640 numbers. 7641 7642 Fixed bug where the return value from Object::SetProperty could 7643 end up being the property holder instead of the written value. 7644 7645 Improved debugger support by allowing nested break points and by 7646 dealing with stack-overflows when compiling functions before 7647 setting break points in them. 7648 7649 7650 2008-07-03: Version 0.1.0 7651 7652 Initial export. 7653 7654 # Local Variables: 7655 # mode:text 7656 # End: 7657
