encoding the values in one word and by using an indirection table for
handles.
This reduces compilation time by roughly 10% and we should be able to make the slow case equality checking of frame elements faster as well.

This will enable reading profiler log in Chrome. The current implementation of memory buffer is trivial (fixed size buffer, no memory recycling) but enough to start end-to-end DevTools Profiler implementation. Later it will be enhanced.

- TARGET, the architecture we will generate code for.
This is brought it from the build system.
- HOST, the architecture our C++ compiler is building for.
This is detected automatically based on compiler defines.
This adds macros for 32 or 64 bit, and cleans up some
include conditionals, etc.

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.

This is an effort to reuse profiler data processing code both in
TickProcessor and Dev Tools Profiler. The old Python implementation
will be removed.
The new TickProcessor works almost identical to the previous one.
However, it has some differences:
1. Not very useful "Call profile" section is replaced with a new
WebKit-like "Bottom up (heavy) profile" which shows the most
expensive functions together with their callers. I used it
personally in order to find and remove bottlenecks in the
tickprocessor script itself, and found it quite helpful.
2. Code entries with duplicate names (they occur for RegExes, stubs
and sometimes for anonymous Function objects) are now distinguished
by adding an occurence number inside curly brackets.
3. (Address -> code entry) mapping is more precise in boundary cases.
4. Windows version no more requires specifying .map file location.
5. Works faster.

Gyp is used to generate project files used to build chromium. Moving
the v8.gyp file to the v8 repository makes it easier to have V8 and
the v8.gyp file synchronized (so a DEPS update in chromium gets the
right v8.gyp file associated with that revision of V8).

This is the first step in reimplementing tick processing scripts in
JavaScript. The goal is to have the same source both for Dev Tools and
Golem, so Python implementation will be removed to avoid code
duplication.
The implementation follows the Dev Tools style: namespaces and JSDocs
are used.

Currently function name inference is wired with AST optimization pass to avoid introducing another pass over AST. A better solution would be to rewrite AST visitors so they can be naturally combined together in a single pass, as their current implementation doesn't allow it.
For examples of cases where function names can be inferred, see the tests file.

Fix exception propagation problem where undefined was returned instead
of an empty handle in case of an exception. This problem can break
C++ programs that are not interested in catching exceptions and just
want to propagate them out by testing for empty handles.
The issue is that exceptions are not rescheduled if they are
externally caught. Externally caught exceptions have to be
rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.
A couple of tests will fail on the ARM simulator because the simulator
has separate stacks for C++ and JavaScript. I have marked the tests
as failing only on the simulator.

and unprotecting it when (re)entering. The functionality is enabled
by the flag --protect-heap and requires V8 to be built with
ENABLE_HEAP_PROTECTION and ENABLE_LOGGING_AND_PROFILING defined.

We know that revision 1383 is causing issues, but I
had to revert some of the other recent RegExp changes
in order to get this part out.

The debugger agent listens on a TCP/IP port for a remote debugger connection. When such a connection is established the debuger JSON protocol is communicated between the agent the the remote debugger. The messages containing the JSON protocol has a RFC-822 like header with a Content-Length field and with the body containing the JSON in UTF-8 encoding.
The D8 shell has option --debugger-agent to start the debugger agent.
