da52a841a3 Add a V8 specific target architecture to the GYP file
The V8 GYP file now uses its own target architecture. It default to the standard target_arch, but can be set to a separate value. E.g. using

  export GYP_DEFINES="target_arch=ia32 v8_target_arch=arm"

makes it possible to have the V8 ARM simulator be used in a IA32 build.

Added some checking of supported host/target architecture combinations.

6f3f2f1c42 Allow new CPU profiling subsystem to coexist nicely with the old one.
This is to make possible enabling usage of the new profiling subsystem
in Chromium without much hassle. The idea is pretty simple: unless the
new profiling API is used, all works as usual, as soon as Chromium
starts to use the new API, it will work too.

51495beb78 Store type information with constants.
Instead of testing the value of a constant frame element to determine
the type we compute its type information at construction time.

This speeds up querying the type information during code generation.

This change also adds support for Integer32 constants and sets 
the type information accordingly.

dbe99e405a Introduce number type information in the virtual frame.
Each frame element gets a new attribute with number type information. A frame element can be: 

- smi 
- heap number 
- number (i.e. either of the above) 
- or something else. 

The type information is propagated along with all virtual frame operations. 
Results popped from the frame carry the number information with them.

Two optimizations in the code generator make use of the new 
information: 
- GenericBinaryOpSyub omits map checks if input operands are numbers. 
- Boolean conversion for numbers: Emit inline code for converting a number (smi or heap number) to boolean. Do not emit call to ToBoolean stub in this case.

64-bit version now builds on Windows again in both release and debug mode.

The Visual Studio project files have been updated so that all three configurations work (32-bit, 64-bit and 32-bit with ARM simulator). They all convert from Visual Studio 2005 to Visual Studio 2008.

999e3fca90 Fix issue 553: function frame is skipped in profile when compare stub is called.
The problem appeared due to a fact that stubs doesn't create a stack
frame, reusing the stack frame of the caller function. When building
stack traces, the current function is retrieved from PC, and its
callees are retrieved by traversing the stack backwards. Thus, for
stubs, the stub itself was discovered via PC, and then stub's caller's
caller was retrieved from stack.

To fix this problem, a pointer to JSFunction object is now captured
from the topmost stack frame, and is saved into stack trace log
record. Then a simple heuristics is applied whether a referred
function should be added to decoded stack, or not, to avoid reporting
the same function twice (from PC and from the pointer.)

37d3972429 Fix issue 571: display descriptive names for code objects from snapshot.
As this is only needed for internal profiling (not for DevTools),
the following approach had been chosen:

 - during snapshot creation, positions of serialized objects inside
   a snapshot are logged;

 - then during V8 initialization, positions of deserealized objects
   are logged;

 - those positions are used for retrieving code objects names from
   snapshot creation log, which needs to be supplied to tick processor
   script.

Positions logging is controlled with the new flag: --log_snapshot_positions.
This flag is turned off by default, and this adds no startup penalty.

To plug this fix to Golem, the following actions are needed:

 - logs created using 'mksnapshot' need to be stored along with VM images;

 - tick processor script needs to be run with '--snapshot-log=...' cmdline
   argument.

339e49c0b2 Added first support for tracking locations of expressions in the
fast-mode code generator.

AST expression nodes are annotated with a location when doing the
initial syntactic check of the AST.  In the current implementation,
expression locations are 'temporary' (ie, allocated to the stack) or
'nowhere' (ie, the expression's value is not needed though it must be
evaluated for side effects).

For the assignment '.result = true' on IA32, we had before (with the
true value already on top of the stack):

32  mov eax,[esp]
35  mov [ebp+0xf4],eax
38  pop eax

Now:

32  pop [ebp+0xf4]


======== On x64, before:

37  movq rax,[rsp]
41  movq [rbp-0x18],rax
45  pop rax

Now:

37  pop [rbp-0x18]


======== On ARM, before (with the true value in register ip):

36  str ip, [sp, #-4]!
40  ldr ip, [sp, #+0]
44  str ip, [fp, #-12]
48  add sp, sp, #4

f74e723599 Initial infrastructure for fast compilation of top-level code. The
fast code generator is optimized for compilation time and code size.

Currently it is only implemented on IA32.  It is potentially triggered
for any code in the global scope (including code eval'd in the global
scope).  It performs a syntactic check and chooses to compile in fast
mode if the AST contains only supported constructs and matches some
other constraints.

Initially supported constructs are

* ExpressionStatement,
* ReturnStatement,
* VariableProxy (variable references) to parameters and
    stack-allocated locals,
* Assignment with lhs a parameter or stack-allocated local, and
* Literal

This allows compilation of literals at the top level and not much
else.

All intermediate values are allocated to temporaries and the stack is
used for all temporaries.  The extra memory traffic is a known issue.

The code generated for 'true' is:

 0  push ebp
 1  mov ebp,esp
 3  push esi
 4  push edi
 5  push 0xf5cca135             ;; object: 0xf5cca135 <undefined>
10  cmp esp,[0x8277efc]

abc0bd46f6 Add initial version of retainers heap profile.
The profile is taken together with constructors profile. In theory, it
should represent a complete heap graph. However, this takes a lot of memory,
so it is reduced to a more compact, but still useful form. Namely:

 - objects are aggregated by their constructors, except for Array and Object
   instances, that are too hetereogeneous;

 - for Arrays and Objects, initially every instance is concerned, but then
   they are grouped together based on their retainer graph paths similarity (e.g.
   if two objects has the same retainer, they are considered equal);

dfcfacf1f9 Enable -fstrict-aliasing in the GYP build of V8 for the Mac in Release mode.
-fstrict-aliasing is enabled by mainline gcc at -O2 and higher, but in Apple
gcc, it must be enabled explicitly.  This results in a 1.5% improvement in V8
benchmark scores.

This also removes the -fno-exceptions and -fno-rtti settings from v8.gyp for
the Mac, and removes -fno-rtti from v8.gyp for Linux, because these settings
have become part of Chromium's common.gypi, included here, as of r23304 at the
latest.  The settings in v8.gyp have become redundant.

MSVS names '.map' file using only module's name, so both 'a.exe' and 'a.dll' will have 'a.map' file. To distinguish an originating module, we're now checking for image base which is always 00400000 for .exe files, and not 00400000 for .dlls.

Verified that windows-tick-processor can now process logs from Chromium using .map file generated for 'chrome.dll', an that it still works for V8's 'shell.exe'.

JS object size is calculated as its size + size of 'properties' and 'elements' arrays, if they are non-empty. This doesn't take maps, strings, heap numbers, and other shared objects into account.

e0b829b1a5 TickProcessor: more accurate mapping of statically compiled code on Linux.
'nm' is now called with an option to report function code sizes. Static code entries are restricted to the sizes reported, and the remaining unnamed code is attributed to a library as a whole. This makes reports more accurate, as some functions are tiny, but has chunks of unnamed code behind them.

This change doesn't affect reporting on Windows, as in .map files function code sizes aren't specified.

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.

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).

e9aa21849b Reimplement Splay Tree in JavaScript (and add unit tests!).
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.

3c2a7bdf21 Add name inference for anonymous functions to facilitate debugging and profiling of JS code.
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.

aacd90314f Reland exception propagation fix.
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.
