while V8 is running.

A debugger using the V8 message based interface now needs to control the
call to DebugBreak in order for the messages send to be processed. Commands can
still be send when V8 is not in a break, but they will not be processed until
there is a break. The response "request queued" when queuing up messages have
been removed. This gets rid of a non JSON message being used.

Modified the threaded debugger tests to call DebugBreak instead of relying
on it occouring automatically.

This change will not be committed until the outstanding Chrome change
http://chrome-reviews.prom.corp.google.com/2072 (which updates Chrome to control
the DebugBreak call) have been reviewed and committed.

now responsible for adding the status information for the tests in the
corresponding test suite.

Added status file from mjsunit tests.

Added tests for known bugs.


git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@29 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

Changed eol-style on debug-sourceinfo.js since the test expects CRLF
endings.

that does not exist locally.  Previously, map transitions broke this
check. 


git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@25 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

Fixed issue with building samples and cctests on 64-bit machines.



git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@23 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

- Fixed mozilla test breakage caused by python's obscure module
  loading rules.
- Made sure test.py propagates test failures out as the exit code of
  the script.
- Remove runtime calls to get number constants. Remove Heap roots for
  some special numbers.
- Fix typo in accessors.h.
- Changes CopyMap to not copy descriptors.  Adds
  CopyMapRemoveTransitions that copies non-transition descriptors.
  Changes interface of DescriptorArray::Copy operations to simplify
  them.

Changed shell sample to take flags directly from the command-line.  Added api call that implements this.

Added better test support.

Added load, quit and version functions to the shell sample so it's easier to run benchmarks and tests.

In the shell sample don't print the result of executing a script, only
evaluating expressions.

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 seperate 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.


git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

Copied version 0.2.3 (trunk@14) to branches/bleeding_edge which will be used for day-to-day development.


git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@15 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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.



git-svn-id: http://v8.googlecode.com/svn/trunk@14 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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.

Cleaned up ARM version by removing top of stack caching and by introducing push/pop elimination.

Cleaned up the way runtime functions are called to allow runtime calls with no arguments.

Changed Windows build options to make sure that exceptions are disabled and that optimization flags are enabled.

Added first version of Visual Studio project files.



git-svn-id: http://v8.googlecode.com/svn/trunk@13 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

git-svn-id: http://v8.googlecode.com/svn/trunk@10 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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.


git-svn-id: http://v8.googlecode.com/svn/trunk@9 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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.


git-svn-id: http://v8.googlecode.com/svn/trunk@8 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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.


git-svn-id: http://v8.googlecode.com/svn/trunk@7 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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.


git-svn-id: http://v8.googlecode.com/svn/trunk@6 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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.


git-svn-id: http://v8.googlecode.com/svn/trunk@5 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

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.
