9c829fafe9 Change the register allocator so that it no longer tracks references 
to the platform-specific reserved registers.  They are always in use
for their intended purpose, cannot appear in the virtual frame, and
can be freely used without allocation in the code generator.

01f7c87f22 This patch much improves our tracking of whether function is 
called from within a loop or not.  In the past we lost the
information if a call site went megamorphic before a lazily
compiled callee was called for the first time.  Now we track
that correctly (this is an issue that affects richards).
We still don't manage to track the in-loop state through a
constructor call, since constructor calls use LoadICs instead
of CallICs.  This issue affects delta-blue.  So in this patch
we assume that lazy compilations that don't happen through a
CallIC happen from inside a loop.  I have an idea to fix this
but this patch is big enough already.
With our improved tracking of in-loop state I have switched
off the inlining of in-object loads for code that is not in
a loop.  This benefits compile speed.  One issue is that
eagerly compiled code now doesn't get the in-object loads
inlined.  We need to eagerly compile less code to fix this.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide. 
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

9f69c414eb Implement resource-saving ("lazy") mode of Profiler. 
This is intended to be used with Chromium. When in resource-saving mode, profiler doesn't consume any resources (sampler and logging is off) until resumed. Then again, when profiler is paused, sampling and logging are turned off.

Tested under Linux and Windows. Also have done preliminary testing with Chromium.

530b86ff17 When message handler is set to NULL and there is no debugger listener the debugger is unloaded immediately unless it's entered, in which case it will be unloaded when last instance of EnterDebugger is destroyed. 
Without the change the debugger may crash as Debugger::EventActive(v8::Break) called from OnDebugBreak may clear current debugger context. 

Also when compilation cache was enabled debugger could fail on second attach for the same reason(see AfterCompileMessageWhenMessageHandlerIsReset).

4075179fbe Introduce Logger::LogCompiledFunctions that logs current map of compiled code. 
The goal is to make possible having --prof flag always enabled in Chromium.  Currently we can't do this because --prof causes compiler and gc to log code creations / moves / deletes which aren't needed until we start profiling.  With LogCompiledFunctions it will be possible not to log anything until we start profiling.  When started, the current map of compiled functions will be logged and compiler / gc logging will be enabled to update current state.  When profling is stopped, logging will be turned off again.

Funny that testing code is actually much longer and complex than function code.

94879a93b0 Add a script cache to the debugger 
When loaded scripts are requested this cache is filled with all the script objects in the heap. Hereafter its content is kept in sync with the active scripts in the heap through the notifications of new scripts compiled and by using weak handles to get notified when a script is collected.

Through the tracking of collected scripts the debugger event OnScriptCollected have been added to notify a debugger that a script previously returned through the scripts command is no longer in use.

Make the ComputeIntegerHash globally available.

Moved clearing of the mirror cache to when debugger is really left. Previously recursive invocations of the debugger cause the mirror cache to be cleared causing handles to become either stale or reference other objects.

83f2c1968f Streamline JumpTarget::ComputeEntryFrame by removing the separate loop 
that sets the static type on elements in the entry frame.  Instead set
the static type as early as possible when computing elements.

Because the elements are shared with the reaching frames, this has the
side effect of sometimes changing the static type of reaching frame
elements.  They will be changed anyway in VirtualFrame::PrepareMergeTo
immediately after, so this is safe.

5fab2d08f2 A register allocation bugfix. 
The function that prepares a virtual frame slot for writing (in order
to preserve the copy-on-write semantics of aliased frame elements) can
allocate registers, which may spill one from the frame.  If we're
unlucky, the spilled register can be the source register for the frame
element write.  In that case, ensure we do the write from memory.

bd3019f2b6 Changed the PageIterator class so that it only returns pages existing 
at construction time.  If allocation during iteration causes a paged
space to expand, the iterator will not return the new pages.

This makes it more closely match the HeapObjectIterator behavior, and
it removes a possible source of bugs (if the allocation top was in the
last page in the space, the old iterator would stop only when it
reached the end of the space, potentially returning invalid pages from
a freshly expanded space).

Still stays within the size of Smi and works with a uint32_t bitfield.
Bitfield might need to be extended to handle a larger base.

Mark all objects reachable from the symbols except the symbols
themselves as live (and reachable from strong roots).  This ensures
that if the symbol itself remains alive for any reason, and if it was
a sliced string or cons string backed by an external string, then the
external string will be strongly reachable and therefore not get a
weak reference callback.

ecd705813f A simple fix of issue http://code.google.com/p/chromium/issues/detail?id=3285 
NPN_Construct allows a NPObject to be called as a construct. For example, the
test case

var s = new app.Packages.java.lang.Integer(5);

app.Packages.java.lang.Integer is a NPObject, and it implements NPN_Construct.

This fix allows a JSObject created by an API function be called as a construct
if it can be called
as a function. This is done by generating the same code for
var s = new app.Packages.java.lang.Integer(5); as
var s = app.Packages.java.lang.Integer(5);

and the caller handles both case correctly. A more sophiscated fix is to one
extra JSConstructCall
frame and allow CallAsConstructor in Builtin::HandleApiCallAsFunction.

This change itself shouldn't affect the semantic of normal case such as:

var a = {};
var s = new a();

A TypeError exception will be thrown in CALL_NON_FUNCTION (runtime.js).

Another part of fix is in the binding code, V8NPObject, which makes
NPN_InvokeDefault or NPN_Construct
call depending on which function is available.

a470847226 Added better version information 
The current version is now held in src/version.cc in a number of defines which needs to be modified when changing version.

The following defines make up the version information:

  MAJOR_VERSION
  MINOR_VERSION
  BUILD_NUMBER
  PATCH_LEVEL
  CANDIDATE_VERSION

The first four are numbers and the fifth is a boolean. Besides these five the define

  SONAME

can be used to set a specific soname when building the a shared library (see below). This will most likely be used on stable branches where binary compatibility is ensured between different versions. This define is a string.

This version information is now read by the SCons build to support setting the soname for a Linux shared library. This requires passing the option soname=on to the SCons build.

When soname=on is specified the soname for the shared library can be set in two different ways. Either it will be the full versioned library name (e.g. libv8-1.2.2.so) or a specific soname defined in src/version.cc. Whenever a shared library is build with an soname the filename of the library will hold the full version name (e.g. libv8-1.2.2.so).

I did not update the xcode project with the new files.

95288e916e Changed the debugger message API to receive an object instead of a JSON string. 
The object delivered to the debug message handler contains additional information on the current break handling the messages.

Clients which require just JSON message parsing can simply get the JSON using the GetJSON message on the message object to still have the previous behaviour.

  NewMessageHangler(const v8::Debug::Message& message) {
    v8::String::Value val(message.GetJSON());
    OldMessageHandler(Vector<uint16_t>(const_cast<uint16_t*>(*val), val.length()));
  }

Refactored some of the debugger code to use internal handles instead of API handles. Also changed Object to JSObject is some places.

The access to the active context when the break occurred is still not implemented. I will add this in a new CL, as this one is quite big already.

f6bafbfb09 Prepare push of version 1.2.1 to trunk. The main reason for this push 
is to get the chromium V8-latest builder working again and to move the
gyp file used for the chromium build to V8 to make it easier to roll
V8 DEPS.

4a909a7a62 - When cloning maps to set the 'lazy loading' bit remember to clone 
the properties as well.  This fixes some failing tests.
- Moved json parsing into native code.

8fefc769f5 Removed the debug message thread. 
The debug message thread was introduced to make it possible to have the message handler callback be called from a different thread than the thread running V8 where the debug event occoured, but it never had any practical use, and prevents providing information to the message handler which is only available from the V8 thread.

In the future any thread decoupling will have do be done by the embedder.

This also removes the queue used for outbound messages.

Renamed the class Message to CommandMessage as it is only used for debugger commands from the client. Related message queue classes has also been renamed.
