531a6db569 Fixed exception in debugger scripts request. 
When collecting the result for a scripts request check that scripts compiled through eval actually have a script for the function they where eval'ed in before adding that informaiton to the response.

a1a962f65e Implemented processing of compressed log files. 
- fixed address delta calculation;
- code creations are also compressed to be in sync with other events;
- factored out a base class from TickProcessor to reuse code in DevTools profiler.

529c3a0a9f Make some small Mac-specific modifications to V8 to make it work on MacOS X 10.4 
rather than just 10.5 and up.
1: Set the right compile flags and predefines to get backward compatible Unix
system calls.
2: Explicitly weak import the functions in execinfo.h and check at runtime to
see if that library loaded before calling backtrace().

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.

02b7894f95 Fix issue 380. 
Don't infer name for a function if a result of its call is assigned to a variable / property. E.g., in this case:

  a = function() { ... } ();

the function must remain anonymous because 'a' doesn't receive a function reference, but instead a result of its call.

91241273cb Fixed pointer vs. va_list overloading problem occuring in gcc 3.3 (used for ARM build). 
It seems that when calling a method that has two overloaded versions like this:
  f(char* format, ...)
  f(char* format, va_list args)
with a second pointer argument: f("format", pointer), the second version is picked up.

I've found a description of a similar issue here: http://bugs.gentoo.org/63112

So, to resolve this ambiguity, I've named such LogMessageBuilder's Append functions differently.

Because of varying floating-point precision, the slow case is hard to
test with explicit values.  Instead, we check that sine and cosine do
not return the same value (the regression was that the slow case of
cosine accidentally did sine instead of cosine).
