a48fd5916e Change the overly-general class named Node to the more specific 
AstNode in case we ever want to have some other kind of node.

Split the NODE_LIST macro-generating macro so that we can iterate
concrete subclasses of Statement and concrete subclasses of Expression
separately.

cffc051177 Avoid dictionary expansion during bootstrapping. 
Allocate the code stubs dictionary and non monomorphic cache dictionary with an initial size which avoids these dictionaries to be expanded during bootstrapping. This gets rid of 9 dictionary expansions during bootstrapping.

Preallocate the dictionary when normalizing an object to a size sufficient for holding the number of properties which is expected to be added to the object. This is used when ceating an object from an object literal boilerplate where multiple properties are known to be added.  This gets rid of 10 dictionary expansions during bootstrapping.

There are now 3 dictionary expansions left during bootstrapping.

98425a31f1 Speed up CalledAsConstructor. 
Changed CalledAsConstructor to process the raw runtime stack directly,
rather than using a StackFrameIterator.  Using an interator turns out
to be quite expensive and the vast majority of the work done is not
relevant to deciding if we've been called as a constructor.

This speeds up getElementById by ~13%.

e97554ed10 Add generic V8 API functions for controlling profiling aspects. 
As we'll have several aspects of heap profiling, it is more handy to control them using binary flags than by individual functions. CPU profiling represent just a particular aspect to control, so {Pause,Resume}Profiler and IsProfilerPaused are only left for compatibility.

For now, PROFILER_FLAG_HEAP_STATS and PROFILER_FLAG_JS_CONSTRUCTOR are equivalent, but later will be split.

9e8216ef22 Introduce first approximation of constructor heap profile for JS objects. 
It is activated with '--log-gc' flag.

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.

As Soeren suggested, I've moved ZoneSplayTree from jsregexp to zone, and removed now empty jsregexp-inl header file.

1cbe7a240a Fix two deallocation bugs identified by Coverity Prevent. 
1. The tables array allocated in the CompilationSubCache constructor
   was never deallocated.  Fixed by adding destructor.

2. The buffer allocated in one of the constructors of the
   NoAllocationStringAllocator was never deallocated.  It seems that
   this class sometimes owns the buffer (if it allocated one itself)
   and sometimes doesn't (if it was passed one).  Simple fix is to
   remove the offending constructor which was never used anyway.

2183309385 Introduce a external allocation limit. 
If V8 is holding on to a lot of external memory, we attempt to clean
it up even if we do not get an allocation failure.  Since tiny V8
objects can hold on to a lot of external memory, we might run out of
external memory while waiting for a normal allocation failure.

00cdc3f1a3 Remove the descriptor stream abstractions. 
The abstractions have led to bugs because it looks like descriptor
streams are GC safe but they are not.

I have moved the descriptor stream helper functions to descriptor
arrays and I find most of the code just as readable now as it was
before.

Storing the breakpoints on the client(in a different process) would be inreliable since 1) it may crash and 2) some 'setbreakpoint' requests may be not processed yet by the time devtools window closes.

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.

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.

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.

b7d48f5807 A bunch of changes to speed up math on ARM. 
* Identify heap numbers that contain non-Smi int32s and do bit
ops on them without calling the fp hardware or emulation.
* Identify results that are non-Smi int32s and write them into
heap numbers without calling the fp hardware or emulation.
* Do unary minus on heap numbers without going into the runtime
system.
* On add, sub and mul if we have both Smi and heapnumber inputs
to the same operation then convert the Smi to a double and do
the op without going into runtime system.  This also applies
if we have two Smi inputs but the result is not Smi.

94a122296d Cleanup of ARM exception handlers. Remove the unused code and 
parameter pointer slots.  Change it so that the handler address no
longer points into the middle of the handler.

f6aa7ce3ee Change the IA32 stack handler layout so that the handler address does 
not point into the middle of the handler.  Also remove top-of-stack
caching from MacroAssembler::PushTryHandler.

6b2a49ff83 * Modify simulator and ARM code generator to avoid swi 
instructions.  The intention is that the snapshots generated
by the simulator should be usable on the hardware.  Instead of
swi instructions we generate a branch to a swi instruction that
is not part of the snapshot.  The call/jump is patched up in
the same way as other external references when the snapshot
is deserialized.  This only works for EABI targets: on old ABI
targets we still emit some instructions not supported by the
simulator (fp coprocessor instructions).
