572a050102 Fix a crash in Logger::LogCompiledFunctions due to a presence of scripts with disposed source. 
When starting JS profiling under Chromium, a map from function addresses to function names is created. During it, for sourceful scripts, an attempt to access script source is made. This can cause a crash, if a source is an external string, which already has been disposed. We had a similar problem in the past with DebugGetLoadedScripts.

bec08c35ca The error cases were returning false instead of true. 
So if the caller does something like:
while(!IdleNotification())
it could spin forever if v8 were not initialized.

I'd like to further remove the is_high_priority flag,
because it is not in use. Mads - is there any reason
not to remove it?

it possible to identify V8 allocations in the vmmap(1) memory profiling tool,
to get a better idea of an embedder's/Chrome's memory usage.

0db55a9456 Do not flatten the string, but just write it out. 
In DOM bindings in many cases the string would be externalized immediately.  For other cases
I am going to add explicit flattening.  Overall, it looks like if user wants to flat string
before writing, it should be an explicit method invocation (going to add TryFlattenIfNotFlat
into public V8 API).

fb038bf146 Two changes, one a refactoring and one that affects V8's JS semantics. 
1. Change the AST node type CallNew to be a subclass of Expression
   rather than Call.  It's not really a call but it just happens to
   have the same fields.

2. Change our error reporting for invalid left-hand sides in for-in
   statements, pre- and postfix count expressions, and assignments.
   Before we signaled a syntax error at compile time *unless* the LHS
   was a function call or 'new' expression, in which case we signaled
   a reference error at runtime.  Now we signal a reference error at
   runtime in all cases.  This matches the JSC behavior in Safari 4.

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);

677c043fee Handle array construction on native code. 
The construction of arrays when using the the Array function either as a constructor or a normal function is now handled fully in generated code in most cases. Only when Array is called with one argument which is either negative or abowe JSObject::kInitialMaxFastElementArray (which is currently 1000) or if the allocated object cannot fit in the room left in new space is the runtime system entered.

Two new native code built-in functions are added one for normal invocation and one for the construct call. The existing C++ builtin is renamed, but kept. When the normal invocation cannot be handled in generated code the C++ builtin is called. When the construct invocation cannot be handled in native code the generic construct stub is called (which will end up in the C++ builtin through a construct trampoline).

One thing that might be changed is preserving esi (constructor function) during the handling of a construct call. We know precisily what function we where calling anyway and can just reload it. This could remove the parameter construct_call to ArrayNativeCode and remove the handling of this from that function.

The X64 and ARM implementations are not part of this changelist.

34d6ff7606 Implemented missing pieces of the debugger for ARM. 
The main piece of this change was to add support for break on return for ARM. On ARM the normal js function return consist of the following code sequence.

  mov sp, fp
  ldmia sp!, {fp, lr}
  add sp, sp, #4
  bx lr

to a call to the debug break return entry code using the following code sequence

  mov lr, pc
  ldr pc, [pc, #-4]
  <debug break return entry code entry point address>
  bktp 0

The values of Assembler::kPatchReturnSequenceLength and Assembler::kPatchReturnSequenceLength are somewhat misleading, but they fit the current use in the debugger. Also Assembler::kPatchReturnSequenceLength is used in the IC code as well (for something which is not related to return sequences at all). I will change that in a separate changelist.

For the debugger to work also added recording of the return sequence in the relocation info and handling of source position recording when a function ends with a return statement.

Used the constant kInstrSize instead of sizeof(Instr).

Removed a false assertion in ScopeIterator that assumed context extension to never be a JSContextExtensionObject.

The context extension object in a 'with' context is JSContextExtensionObject iff the 'with' statement is generated from a catch block in order to extend its local scope with a variable holding exception object. This is how we differentiate 'catch' scope from 'with' scope.

def729b6ad Change to limit the amount of space we waste due to fragmentation 
in old space. Before this change we would compute the fragmentation 
limit before the GC, but that means that we take all the garbage 
into account - and consequently we almost never hit the limit (because 
we have a lot of garbage).

This change changes the policy to compact on the *next* GC if we
determine that we have too much fragmentation after doing a GC.
We'll do a GC if we've wasted more than 1MB and more than 15% of
the old space size.

This can be further improved by computing whether or not to compact
during the marking phase.

717394492d Generate specialized constructor code for constructing simple objects. 
For objects which only have simple assignments of the form this.x = ...; a
specialized constructor stub is now generated. This generated code allocates the
object and fills in the initial properties directly. If this fails for some
reason code continues in the generic constructor stub which in turn might pass
control to the runtime system.

Added counter to see how many objects are constructed using a specialized stub.

The specialized stub is only implemented for ia32 architecture in this change.
For x64 and ARM the generic construct stub is used.

This is change is identical to http://codereview.chromium.org/174392 (committed in r2753 and reverted in r2754) except that a few parts have already been committed from http://codereview.chromium.org/173469 (committed in r2762).

When copying a map always set the descriptor array to describe the pre-allocated properties, even when descriptors are to be dropped.

Added a test which otherwise failed with an assert on ARM in debug mode. The reason for it only surfasing on ARM is that the NewObject runtime function is always used for allocating new JSObjects on ARM.

53531ed48a Generate specialized constructor code for constructing simple objects. 
For objects which only have simple assignments of the form this.x = ...; a specialized constructor stub is now generated. This generated code allocates the object and fills in the initial properties directly. If this fails for some reason code continues in the generic constructor stub which in turn might pass control to the runtime system.

Added counter to see how many objects are constructed using a specialized stub.

The specialized stub is only implemented for ia32 architecture in this change. For x64 and ARM the generic construct stub is used.

4e03645dc4 Analyze functions for assignment to this properties. 
During parsing functions are analyzed for statements of the form this.x = ...;. These assignments are categorized in two types: simple and non simple. The simple ones are where the right hand side is known to be either a constant or an argument to the function. If a function only contains statements of this type the property names are collected and for the simple assignments the index of the argument or the constant value assigned are stored as well.

When the initial map for a function is created and the function consists of only this type of assignemnts the initial map is created with a descriptor array describing these properties which will be known to always exist in an object created from the function.

The information on this property assignments is not collected during pre-parsing so if compiling using pre-parse data these optimization hints are not available.

Next step will be to use the information collected for the simple assignments to generate constructor code which will create and initialize the object from this information without calling the code for the function.

9edc69c72f Add support for (some) assignment expressions to the CFG builder and 
fast-mode compiler.

1. We avoid generating a useless temporary for assignments with
nontrivial right-hand sides.  Instead of translating id = expr into:

...
tmp = <last expr instruction>
id = tmp

we generate directly

...
id = <last expr instruction>

by passing a data destination ('hint') down the AST.  The semantics is
to use the destination as a result location if a temp is needed.  It
may be ignored.  NULL indicates I don't care and you should generate a
temp.

2. We correctly handle assignments as subexpressions.  When building
the CFG for an expression we accumulate the assigned variables and we
emit a move to a fresh temporary if a value in a variable is in
jeopardy of being overwritten.

98b93c739d Added support for expression statements to the CFG builder and 
fast-mode compiler.

This will generate a compiler temporary for complex expressions and
then immediately throw it away, so a better approach (to be
implemented later) is to pass to the expression builder whether an
expression is in an effect or value context.

23fbd8fe3f Add support to the CFG builder for non-short-circuited binary 
expressions.  Add compilation support in fast mode (optimized for
compilation time and code size).

This breaks one debugger test each on ARM and IA32 (expectedly).

5470f9b132 Add an ability to initiate GC through V8 API. 
I'm planning to use it in DevTools heap profiler. It is a common scenario in debugging memory leaks to enforce GC, then perform an operation, then enforce GC again to check for non-collected (that is, leaked) objects. Using the existing GC extension isn't possible because it doesn't exposed in the normal operation mode of Chromium.
