00b9b2e5e4 Cleanup v8.gyp. This also drops a bunch of unused targets (the shell, d8,
etc).

There are now two gyp variables to control whether we build snapshots and which
target we are building for.  This allows you to easily cross-compile for arm and
disable snapshots.

6b03961d4c Fix 'nm' results parsing in tickprocessor.
Without an explicit check if a function belongs to shared library address space, "finishing" a library symbols processing with 'addPrevEntry(libEnd);' can cause emission of code entries which cover almost the entire address space, shadowing other code.

2cc6fef9d5 Fix the problem with JS entries in tickprocessor.
The main problem was due to the following: after Erik had fixed the logger to report library addresses, tickprocessor started to add to the code map entries that covered almost entire memory. This happened because tickprocessor contains a heuristic to bias addresses of functions from dynamic libraries:

    if (funcInfo.start < libStart && funcInfo.start < libEnd - libStart) {
      funcInfo.start += libStart;
    }

And, as tickprocessor tried to process all symbols from the library, including data entries, which can be outside reported library addresses range, the second condition failed, and funcInfo.start remained unbiased.

78a8cdfbe8 Added utility scripts for running oprofile in tools/oprofile.
To profile running the JavaScript file test.js using the V8 release mode shell (assuming it is build passing prof=oprofile to the SCons build). The following commands can be used:

$ tools/oprofile/start
$ tools/oprofile/run test.js
$ tools/oprofile/report | less
$ tools/oprofile/annotate | less
$ tools/oprofile/shutdown

Here is a summary of the commands.

For all the commands taking an executable the executable is expected to be a binary using V8. If no executable is specified the release mode V8 shell is assumed.

By default the --session-dir=/tmp/oprofv8 is passed to all oprofile commands. This walue can be changed by setting environment variable OPROFILE_SESSION_DIR.

When using the defaulf executable (V8 shell in release mode) it is assumed to be located in ../.. relative from the oprofile utility scripts. This default location can be overridden using the V8_SHELL_DIR environment variable.

start
-----
Start the oprofiling daemon.

run [executable] [parameters]
-----------------------------
Profile a V8 executable. Running this will reset oprofile samples, run the command and do an oprofile dump to flush samples and write ELF binaries for the generated code. The parameters are passed to the executable together with the --oprofile option.

report [executable] [parameters]
--------------------------------
Print the report for a profile run. The parameters are passed to opreport. E.g report --callgraph.

annotate [executable] [parameters]
----------------------------------
Print annotated assembly for a profile run. The parameters are passed to opannotate. E.g annotate -threshold 1.

reset
-----
Reset oprofile samples.

dump
----
Flush oprofile samples and write ELF binaries for the generated code.

shutdown
--------
Shutdown oprofile daemon.

Added a warning which is printed if option --oprofile is passed to a V8 which has not been compiled with oprofile support.

d7cccf6b8d Add log compression ability.
This is a trivial per-row compression:
- short aliases are introduced for events and code creation tags;
- in tick events, offsets are used instead of absolute addresses;
- removed 'code-allocation' event, as it seems not used.

The first two options are depend on the new flag: 'compress-log', which is off by default.

On benchmarks run w/o snapshot, this gives 45% log size reduction.

e48095b87c Implement a dynamically growing memory log buffer with an upper limit.
The goal of this change is to allow longer profiling sessions and preserve memory when profiler isn't started. The buffer starts with 64K and grows until it reaches the upper limit, which is currently set to 50MB --- according to my evaluations, this is enough for at least 20 minutes of GMail profiling. As we're planning to introduce compression for the profiler log, this time boundary will be significantly increased soon.

To make possible unit testing of the new component, I've factored out Logger's utility classes into a separate source file: log-utils.h/cc. Log and LogMessageBuilder are moved there from log.cc without any semantical changes.

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.

aa2c33126c TickProcessor script reimplemented in JavaScript.
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.

e3e50f7070 Add gyp file to v8 repository.
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).

2060dc1512 Added ProfileView object for performing sorting, searching and filtering operations on a profile.
It will be used both in the new tickprocessor and Dev Tools profiler.
