d9285da2a8 By default disable the general protection fault message box when 
running tests on Windows. This requires 

Added the option --win-error-box to enable general protection fault
message box which can be convenient when debugging failing tests on
Windows.

Added crash detection when running tests on Windows. The output
is not fully polished but crashed indications are printed for the
different progess indicators.

Changed the OS::Abort on Windows from generating a "crash" (int3)
to calling abort(). This is to avoid tests which are known to fail
with out of memory errors to be detected as crashed tests.

4c1a5810b9 Implement Array::concat function in C++. 
The performance of Array::concat is critical of jQuery benchmark from
http://www.dromaeo.com. Our current implementation in JavaScript is very
generic and is several times slower than JSC and SpiderMonkey.

Re-implement Array::concat in C++ to take advantage of underlying implementation
details. This cuts dom-travesal-jquery execution time by half.

We may want to move Array specific implementation into a separate source file,
say jsarray.cc.

0fc72f2b4e Serendipitously arrange the tags so that String.length() becomes a branch-free 
operation.  I have another version of this change that does not remove the
special inline caches for difference sized strings.  The other version is ever
so slightly faster, but the nice thing about this version is that it removes
253 lines of code.

42ef2c3d77 Split window support from V8. 
Here is a description of the background and design of split window in Chrome and V8:
https://docs.google.com/a/google.com/Doc?id=chhjkpg_47fwddxbfr

This change list splits the window object into two parts: 1) an inner window object used as the global object of contexts; 2) an outer window object exposed to JavaScript and accessible by the name 'window'. Firefox did it awhile ago, here are some discussions: https://wiki.mozilla.org/Gecko:SplitWindow. One additional benefit of splitting window in Chrome is that accessing global variables don't need security checks anymore, it can improve applications that use many global variables.

V8 support of split window:
  There are a small number of changes on V8 api to support split window:
Security context is removed from V8, so does related API functions;
A global object can be detached from its context and reused by a new context;
Access checks on an object template can be turned on/off by default;
An object can turn on its access checks later;

  V8 has a new object type, ApiGlobalObject, which is the outer window object type. The existing JSGlobalObject becomes the inner window object type. Security checks are moved from JSGlobalObject to ApiGlobalObject. ApiGlobalObject is the one exposed to JavaScript, it is accessible through Context::Global(). ApiGlobalObject's prototype is set to JSGlobalObject so that property lookups are forwarded to JSGlobalObject. ApiGlobalObject forwards all other property access requests to JSGlobalObject, such as SetProperty, DeleteProperty, etc.

  Security token is moved to a global context, and ApiGlobalObject has a reference to its global context. JSGlobalObject has a reference to its global context as well. When accessing properties on a global object in JavaScript, the domain security check is performed by comparing the security token of the lexical context (Top::global_context()) to the token of global object's context. The check is only needed when the receiver is a window object, such as 'window.document'. Accessing global variables, such as 'var foo = 3; foo' does not need checks because the receiver is the inner window object.

  When an outer window is detached from its global context (when a frame navigates away from a page), it is completely detached from the inner window. A new context is created for the new page, and the outer global object is reused. At this point, the access check on the DOMWindow wrapper of the old context is turned on. The code in old context is still able to access DOMWindow properties, but it has to go through domain security checks.


It is debatable on how to implement the outer window object. Currently each property access function has to check if the receiver is ApiGlobalObject type. This approach might be error-prone that one may forget to check the receiver when adding new functions. It is unlikely a performance issue because accessing global variables are more common than 'window.foo' style coding.

I am still working on the ARM port, and I'd like to hear comments and suggestions on the best way to support it in V8.

c0e04e1e86 Fixed unsafe code where a GC could occour after a Handle had been deferenced. 
instances->set(i, *GetScriptWrapper(script));

GetScriptWrapper can call GC. The failure have only been seen on ARM, where
the g++ compiler pulls out the object from the instances handle to a register
before calling GetScriptWrapper causing set to be called on an object which
may have moved.

Marked a test on ARM as no longer flaky, whereas two other fails consistently
but that is no longer related to the problem fixed above.

4fe70e49b6 Fix ARMu debug mode failure by handling runtime calls 
with the wrong number of arguments on ARM in the same
way it's done on IA32. Make sure to remove arguments
on both platforms and return the illegal result in 
register eax or r0.

d2a8454d2f This change removes the %AddProperty native JavaScript function from V8. 
All uses of %AddProperty are replaced by %SetProperty.  A few uses of
IgnoreAttributesAndSetLocalProperty are added, and the runtime version
of it adds a PropertyAttributes argument.  Only the JSObject class
in objects.cc now uses AddProperty, and it can become private.

b568d7a17b Defer the writing of the source position data to the relocation information 
until a possible debug break location is reached. Currently this is call sites
with calls to code objects and JS return. Source position information in the
code therefore no longer refers to the "first" instruction generated for a
given source position (which was not the case defered code anyway) but to the
first break location after that source position was passed (again defered code
always start with source position information). This doesn't make a difference
for the debugger as it will always be stopped only at debug break locations.
However, this makes the life of the peep-hole optimizer much easier as many
oportunities for posh/pop eliminations where previosly blocked by relocation
information already written to the code object.

Two types of source positions are still collected. Statement positions indicate
the position of the start of the statement leading to this code and (plain)
positions indicate other places typically call sites to help indicate current
position in backtraces. The two different types of positions are also used to
distinguish between step next and step in.

Runs all the tests (including debugger tests) as before.

Moved the checking for the FLAG_debug_info to one place.

I will do the same changes to the ARM codegenerator in a seperate changelist.

- Start introducing convenience instructions in the ARM assembler as needed. These instructions take all Register parameters to avoid extra typing of "Operand(reg)".


To keep the architectures in sync these changes have been made to the ia32 files:
- Changed MacroAssembler::EnterFrame(StackFrame::Type type) to MacroAssembler::EnterInternalFrame().


These parts are still missing:
- unimplemented: Builtins::Generate_FunctionApply - large limit
- unimplemented: Builtins::Generate_ArgumentsAdaptorTrampoline - non-function call
- The files have not been lint'd yet.

b5a72a1645 Generalized the EvalCache into a CompilationCache and enabled 
it for scripts too. In the context of Chromium, this should 
have a very positive impact on memory consumption for web apps
that run multiple tabs from the same domain with a lot of the
same JavaScript code.

For now, the cache retirement policy is really simple:
Whenever a mark-sweep collection is started we clear the
cache. This guarantees that this change will not have a
huge negative impact on memory consumption, but it may
not be ideal. We should consider a more sophisticated LRU
scheme.

4d95ac7339 Added option for TryCatches to not capture the message object on 
exceptions.

It turned out that the stack overflow fix from before had disabled
message storing in another test.  Previously, stack overflows would
actually cause a message object to start being created but cause
another exception which would not be reported and that's what stopped
the infinite regress.  This change resores that behavior.

1461117cd4 Add option 'env' 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 envrionment
variables.

9cd4196c55 Created a factory method for allocating the debug info object. The new 
method ensures that there are no allocations during the setup.

This fixes test breakage on Linux in debug mode where allocation
happened while the debug info object was not fully set up making
verify heap unhappy.

6d4d692ec7 Removed the implicit call to DebugBreak when receiving debugger commands 
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.

968facb9ff - Fixed issue when building samples and cctests on 64-bit machines. 
- 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.

c42f5829a1 Included mjsunit JavaScript test suite and C++ unit 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.

Added Visual Studio project files for the shell.cc and process.cc samples.

31e7138e1a 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.

769cc962a0 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.

7276f14ca7 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.

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.

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.
