a968ed0470 Implement HeapIterator that skips over unreachable objects. 
I'm using it when creating heap snapshots. I decided that it will
be more convenient to have it as a separate piece of code, instead
of embedding into the snapshot generator.

ae476ecd6c Teach C++ ArraySlice builtin to deal with arguments object. 
Array.prototype.slice.call(arguments, ...) idiom is pretty common (up to 97% of invocations
in GMail), so we'd better handle it efficiently too.

357afa385b Change Object.defineProperty to accept undefined as getters and setters and to correctly accept overriding an accessor with a data property. 
In the past we only accepted functions as argument for setting an
accessor. Since one should be able to set an accessor to undefined
this had to be changed to take either.

In addition, we did not lookup properties in the prototype chain,
causing us to call the setter of an existing accessor up the prototype
chain when trying to replace an existing accessor (that was not local)
with a data property.

ace6290452 Fix issue 974. 
When entering a finally block in unoptimized code, we unconditionally
save the accumulator register in the stack in case it holds a return
value or an exception.  In the case of a break, continue, or falling
off the end of the try or catch block, this value is unpredictable and
not necessarily safe for GC.

d9c202752e Initial attempt to add support for using gyp to build V8 itself 
This is based on the structore used in chromium with a script wrapping the call to gyp itself and the default processing of common.gypi.

It is possible to build all our targets on Intel Linux for all architectures (ia32, x64 and ARM simulator). When this is committed I wil take a look at Windows.

See the README.txt file in the changelist for the current way of using it.

49f4c39d6d Deoptimize to the proper target after assignment side effects. 
This fixes V8 issue 989.

Before, assignments used the AST ID of the assignment expression to
mark the side effect of the store, which became a target for
deoptimization bailout for code after the assignment.  In effect
contexts this environment included the value of the assignment, which
was unexpected by the unoptimized code.

Now we introduce a new assignment ID for AST node types that include
an assignment (Assignment, CountOperation, and ForInStatement) and use
it for the side effect of the store.

As taking a snapshot of a large heap takes noticeable time, it's
good to be able to monitor and control it.

The change itself is small, big code deletes and additions are in
fact moves. The only significant change is simplification of

e0d3f6afdf Be more careful about exiting inlined functions in a test context. 
When falling off the end of a function inlined in a test context, we cannot
constant fold the test of undefined away. The graph builder assumes that
control flow always reaches both branches of a test.

Instead, explicitly test and branch on "undefined". Introduce a pair of
empty blocks to hold the necessary LeaveInlined instructions.

7be18f702b make DateParser::TimeComposer handle 1-2 digits millisecond values 
see http://code.google.com/p/v8/issues/detail?id=944
This patch makes DateParser::TimeComposer process times that have
millisecond values with only 1 or 2 digits.

Without this patch, Date.parse("2010-11-25T22:02:30.5") returns
1290690150005 and
Date.parse("2010-11-25T22:02:30.5") == Date.parse("2010-11-25T22:02:30.005")
evaluates to true.

With this patch, Date.parse("2010-11-25T22:02:30.5") returns
1290690150500 instead, and
Date.parse("2010-11-25T22:02:30.5") == Date.parse("2010-11-25T22:02:30.005")
evaluates to false.

 - HeapEntryCalculatedData (size is now stored in the node, retaining

051f314a99 New heap profiler: include all heap objects and refs into snapshot. 
Otherwise, retaned memory sizes are not precise. This increases size
of heap snapshot, I will deal with this later. Heap objects and
references previously missing in snapshot are now marked as 'hidden'.
That means, they not shown to user, but participate in sizes
calculation.

Other small changes:
 - added 'shortcut' graph edges: e.g. to pin global objects on top
   level;
 - meta-information in JSON snapshot is no more double encoded.

This aligns DevTools Timeline stats with Heap profiler stats.

Instead of relying on itimer signals from kernel, send them
ourselves from a separate thread. This disables an ability
to profile multiple VM threads on Linux, but it anyway doesn't
work on other platforms, so we need a common solution for
it (issue 913 created to track this).

9673ee5d59 Get rid of requested size in RetryAfterGC. 
This was only used by Heap::CollectGarbage to check if after GC
available space is bigger than was requested, but nobody checked
the value returned by Heap::CollectGarbage, so requested size
was efficiently unused.

However, it may trigger spurious out of memory exceptions if requested
size is big enough.

d4bc8e1585 New Heap profiler: add dumping HeapNumbers and InternalFields to snapshot. 
HeapNumbers do consume memory, so it's worth dumping them. However, we
don't dump their values, as they are not as self-descriptive as values
of strings, and they will increase snapshot size. Storing heap numbers
values can be added if we will feel a sufficient demand for that.

InternalFields are used, e.g. for storing references to DOM nodes
event handlers.

otherwise, an object that is already disconnected, but not discarded
yet, will not appear as a deleted (thankfully, this bug for some

d46fb9d454 New attempt to make the allocation routines 64 bit clean. 
This one has been approved by the 64 bit compiler in MSVC
2005 so I hope it also passes the 2008 version.

The --max-new-space-size option is now in kBytes.
The --max-old-space-size option is now in MBytes.

Some issues remain with 64 bit heaps and the counters.  See

2d0c23bc82 Revert attempt to make heap size 32/64 clean. This change needs to 
be done from Windows where the compiler is stricter about truncating
changes.

f1635606df Use intptr_t instead of int for heap sizes. This is a step towards 
removing the 1Gbyte limit.
