c093e94546 - Pass the knowledge whether the old GC is compacting to the GC prologue and epilogue. This allows us to skip frame cooking and uncooking when doing a mark-sweep GC.
- Add the ability for the code to refer to its code object by adding a handle to the code object in the MacroAssembler.

632d4e4f3d Adding unit tests for profiler's stack tracer.
The testing is a bit tricky because we need to obtain a frame
pointer (EBP on IA-32) from inside of a function. This is especially
interesting in case of a compiled JavaScript function.

6ace05ed2a Issue 63: Running tests fails of there is a dot in the checkout path
Patch by Matt Hanselman (http://codereview.chromium.org/27086). Pass in the module's filename while loading rather than the full path (so call to load_module now matches find_module).  Otherwise dots in path name get mistaken for file suffixes.

Added Matt Hanselman to AUTHORS file.

be059966c1 Add socket support to platform code.
The new Socket class is an encapsulation of the standard BSD socket API. As it depends on platform specific include files and have some slight platform variations it is part of the platform code.

On Mac OS only the option SO_REUSEADDR is set to true for server sockets. Running the test required it as the bound listener socket would sometimes end up in TIME_WAIT. On Windows and Linux this has never been observed (given the client end of the socket is closed before the server end).

The code has been tested on Windows, Linux and Mac OS. The FreeBSD version is a copy of the Linux version but has not been compiled nor tested.

Missing Xcode project updates.

0c7af39737 Speed up access to global variables from eval scopes. Traverse the
surrounding context to figure out if the variable could be global.  If
the variable could be global we check context extension objects at
runtime and use a global LoadIC if no variables have been introduced
by eval.

Fix crash bug when loading function arguments from inside eval.  The 
shadowed variable in the DYNAMIC_LOCAL case does not rewrite to a slot in 
that case.

checks are not needed.  If we fail to store the float as a 64-bit
integer, we just go to the runtime system.  The only extra case in

44b83d3e77 Add host callback for debug break.
Add the ability to have the host embedding V8 receive a callback in the V8 thread while V8 is processing a debug callback. When V8 is processing a debug callback the thread where V8 is executing is sitting in a tight loop processing debug commands until the continue command has been executed. In some embedding situations it is beneficial to be able to call back into the embedding host from the thread where V8 is sitting. The might have functions which needs to be called to complement the JavaScript debugging.

Using the uint16_t array to pass a void* is a temporary hack.

a09832ab76 Optimize loads from variables that might be shadowed by variables
introduced by eval.

In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call.  Instead, we verify that the
context extension objects have not been created and perform a direct
load.

Not implemented for ARM yet and the scope resolution code could use
some better abstractions.  I'd like to do that in a separate
changelist.

577741308b First step in refactoring the logging system to allow the logging messages to have other destinations than an open file.
This change introduces a log message builder which builds the log message in a static string buffer instead of formatting the log message through fprintf. Currently this message can only be written to a file afterwards.

Changed the code related events to use the log message builder.
