17362b27ea Changed RegExp parser to use a recursive data structure instead of stack-based recursion. 
Shouldn't run out of stack space while parsing deeply nested regexps.
Might be a little faster.

25405ddd9c Handle JavaScript accessors on the global object. 
With the new representation of the global object adding JavaScript accessors for a property after global inline caches was created for that property did not work property as the inline caches did not take the JavaScript accessor information (fixed array with two elements) that could be present in a global object property cell into account.

This is now fixed by changing the map for a global object when a JavaScript accessor is defined on it.

8318f5e5f1 Reimplement profiler sampler on Mac OS X to get it working under Chromium. 
Previous implementation of sampler for OS X was copied from the Linux one. But BSD (OS X) and Linux has a very important difference in signal handling. LinuxThreads doesn't support the notion of process-directed signals. So, the SIGPROF signal was directed to the thread that installed the handler---the V8 thread. But on BSD, signal handling is implemented according to POSIX spec, where process-directed signal is to be handled by an arbitrary selected thread. By a coincidence, in V8's sample shell and in Chromium's test shell, V8's thread was picked almost every time, so sampling seemed working. But not in case of Chromium.

So, I've changed the implementation of profiler sampler to use the same scheme as on Windows---a dedicated thread with high priority is used to periodically pause and sample V8's thread.

92bb897081 Tweaks to global object inline cache code. 
Remove the check for deleted properties in the global load inline cache if the property is known to be read only.

Propegate the in loop flag for the global call inline cache.

Changed the propagation of the code flags in the call stub compiler to compute these the same way for all types of call stubs and assert that the flags for the generated code is the same as those used for the cache lookup.

Addressed a few comments from previous review in test-api.cc.

118a2ccc8e When Error.collectStackTraces is set to true all new instances of 
Error, ReferenceError, etc. are given a stack property that gives a
stack trace.  Here's an example stack trace:

ReferenceError: FAIL is not defined
    at Constraint.execute (deltablue.js:527)
    at Constraint.recalculate (deltablue.js:426)
    at Planner.addPropagate (deltablue.js:703)
    at Constraint.satisfy (deltablue.js:186)
    at Planner.incrementalAdd (deltablue.js:593)
    at Constraint.addConstraint (deltablue.js:164)
    at Constraint.BinaryConstraint (deltablue.js:348)
    at Constraint.EqualityConstraint (deltablue.js:517)
    at chainTest (deltablue.js:809)
    at deltaBlue (deltablue.js:881)
    at deltablue.js:888

If Error.prepareStackTrace holds a function this function is used to
format the stack trace, for instance allowing code generators to
customize the way stack traces are reported to make them easier to
process.

Next step: performance measurements to see if it is feasible to turn
this on by default.

a54a4ada5c Changed the global object representation.The global object is now always in dictionary (slow) mode with each of its properties stored in a cell object. A cell object has one field containing the actual value for the property. Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.

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.

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.

3a3a6924a1 Involve more log compression techniques. 
Code addresses are now written as an offset from the previous address for ticks, code move and delete events. Employed backreference and RLE compression for code move and delete events. This gives additional 30% log size reduction for benchmarks run w/o snapshot.

Overall compression results (compared with the revision of V8 having no compression):
 - V8: 70% size reduction for benchmarks run w/o snapshot (for reference, gzip gives 87%)
 - Chromium: 65% size reduction for public html version of benchmarks (v4) (for reference, gzip gives 90%)

The one obvious opportunity for improving compression results in Chromium is to compress URLs of scripts.

882614391f Add scope chain information to the debugger. 
For each frame it is now possible to request information on the scope chain. Each scope in the chain can have one of the types local, global, with and closure. For scopes of type global and with the mirror for the actual global or with object is available. For scopes of type local and closure a plain JavaScript object with the materialized content of the scope is created and its mirror is returned. Depending on the level of possible optimization the content of the materialized local and closure scopes might only contain the names which are actually used.

To iterate the scope chain an iterator ScopeIterator have been added which can provide the type of each scope for each part of the chain. This iterator creates an artificial local scope whenever that is present as the context chain does not include the local scope.

To avoid caching the mirror objects for the materialized the local and closure scopes transient mirrors have been added. They have negative handles and cannot be retrieved by subsequent lookup calls. Their content is part of a single response.

For debugging purposes an additional runtime function DebugPrintScopes is been added.

Added commands 'scopes' and 'scope' to the developer shell and fixed the dir command.

8c16bc13bc Implement tick events compression in a log file. 
Two techniques are involved:
 - compress repeated line ends (common stack beginnings) by using back references;
 - do RLE compression of repeated tick events.

This gives only 5% size reduction on benchmarks run, but this is because tick events are only comprise 10% of file size. Under Chromium winnings are bigger because long repeated samples of idleness are now compressed into a single line.

Tickprocessor will be updated in the next patch.

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.

d498361c5f Add more debugging information to scripts compiled through eval. 
Scripts now have a compilation type which can be host, eval or JSON. Host scripts are compiled through the API, eval scripts are compiled through call to evan and JSON scripts are compiled as a result of calling JSON.parse.

For scripts scripts compiled through eval the JavaScript function in top of the stack and the pc offset into the code is stored in the script object. This makes it possible to calculate the source position of the eval call later when requested. This information can be obtained through the script mirror object and is part of the script mirror JSON serialization for the debugger protocol.

Moved the enumeration ScripType into class Script and remamed to Type. The new compilation type enumeration is also inside the class Script.

This information is now shown when using the scripts command in he developer shell debugger.

cache to 5 (down from 8). Generations 5, 6, and 7 are 
rarely hit in real browsing sessions (~2% in the best case)

bd82b972fc Simplify the processing of deferred code in the code generator. Our 
deferred code snippets are highly stylized.  They always make a call
to a stub or the runtime and then return.  This change takes advantage
of that.

Creating a deferred code object now captures a snapshot of the
registers in the virtual frame.  The registers are automatically saved
on entry to the deferred code and restored on exit.

The clients of deferred code must ensure that there is no change to
the registers in the virtual frame (eg, by allocating which can cause
spilling) or to the stack pointer.  That is currently the case.

As a separate change, I will add either code to verify this constraint
or else code to forbid any frame effect.

The deferred code itself does not use the virtual frame or register
allocator (or even the code generator).  It is raw macro assembler
code.

0a0ede0716 Fix the issue with layout tests. 
The problem was I incorrectly treated NULL result as failure to fetch
a property with a getter.  However, if getter returns zero, it is
manifested as NULL pointer (see added test case).

Good news: that gives another boost as before this CL if getter returned
0, I did another slow lookup.

0fcedde224 Fix determining of JS lower stack bottom used in profiler's JS stack tracer to work with Chromium. 
My assumption that log initialization happens somewhere near the stack's bottom is true for V8's sample shell but isn't true for Chromium, causing many otherwise valid stack addresses to be thrown out. The solution proposed is to save stack pointer value for the outermost JS function in ThreadLocalTop similar to c_entry_fp.

Implemented only for IA-32. Currently I'm not dealing with profiling on ARM and x86-64 anyway.

a019501be2 Change the handling of the debug break stack guard. The debug break is no longer ignored when hit inside "system" JavaScript. The reason for this is twofold: 
* Running "system" JavaScript with the debug break flag active leads to slow running code while waiting for the break in non "system" JavaScript (one exception to this it is to try to avoid breaks in the clear mirror cache JavaScript code called when leaving the debugger).

* If this happens while processing RegExp running in native code an infinite loop is created as the stack guard handler for RegExp does not move execution forward

Fixed a GC bug in the interrupt handling for RegExp running in native code.

Added test of debug break while in debug message handler callback and debug break while executing a RegExp.

When profiler's memory buffer is filled up, profiling is stopped and it is ensured that the last record in the buffer is "profiler,\"pause\"" thus making the end of profiling session explicit. Otherwise DevTools Profiler would need to guess whether the current profiling session has been stopped.

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.

9c829fafe9 Change the register allocator so that it no longer tracks references 
to the platform-specific reserved registers.  They are always in use
for their intended purpose, cannot appear in the virtual frame, and
can be freely used without allocation in the code generator.

01f7c87f22 This patch much improves our tracking of whether function is 
called from within a loop or not.  In the past we lost the
information if a call site went megamorphic before a lazily
compiled callee was called for the first time.  Now we track
that correctly (this is an issue that affects richards).
We still don't manage to track the in-loop state through a
constructor call, since constructor calls use LoadICs instead
of CallICs.  This issue affects delta-blue.  So in this patch
we assume that lazy compilations that don't happen through a
CallIC happen from inside a loop.  I have an idea to fix this
but this patch is big enough already.
With our improved tracking of in-loop state I have switched
off the inlining of in-object loads for code that is not in
a loop.  This benefits compile speed.  One issue is that
eagerly compiled code now doesn't get the in-object loads
inlined.  We need to eagerly compile less code to fix this.
