7c5cca2927 Don't return false from CompileCallInterceptor which returns a 
MaybeObject*. Instead return the failure which will be handled
correctly by the caller. This code would lead to a crash if ever
executed.

051f314a99 New heap profiler: include all heap objects and refs into snapshot. 
Otherwise, retaned memory sizes are not precise. This increases size
of heap snapshot, I will deal with this later. Heap objects and
references previously missing in snapshot are now marked as 'hidden'.
That means, they not shown to user, but participate in sizes
calculation.

Other small changes:
 - added 'shortcut' graph edges: e.g. to pin global objects on top
   level;
 - meta-information in JSON snapshot is no more double encoded.

48066af7e0 Landing for Justing Schuh. 
Split out the random number state between JavaScript and private API

I've added v8::RandomPrivate() for internaly used random numbers, and pass the state in as a parameter to a random_base function.

I still need to implement strong seeding. I already know how and will be landing that in another patch.

a298666fae Store script's line ends in copy-on-write fixed array. 
This allows to remove explicit copy from line ends JS accessor which is used for formatting of stack traces.

Eager copying of line ends array might cause multiple full GC collections for huge scripts (e.g. scripts generated by GWT compiler with PRETY preset).

2a8eb35548 Provide more accurate results about used heap size via GetHeapStatistics. 
I observed that used heap size provided by Heap::SizeOfObjects() is
usually about ~10% bigger than the number calculated by summing up
heap objects sizes.

This aligns DevTools Timeline stats with Heap profiler stats.

0f66199b5e Heap profiler: remove context checks for objects. 
It seems that there will be no access to heap snapshots from
web pages' code, only from Developer Tools, thus it makes no
sense doing filtering of object by their security contexts.

Make checks.h not depend on flags.h or global.h (or anything else except
include/v8stdint.h). Only checks.cc has the dependencies (so another
implementation of checks.cc can be provided by the preparser).
Now files depending on checks.h (using ASSERT macros) can include it
directly without depending on all of v8.

20938fc53c Attempt to collect more garbage before panicking with out of memory. 
Currently weak handles retain an object for another GC round (oftem times,
major GC round.)  Instrumenting Chromium shows that navigation leaves
many global objects which are only collected in next go.  Let's
attempt to collect more garbage when approacing OOM condition.

This is a better version of rolled out r5455: now it's correctly
rebuilds object groups between additional GCs.

e6b33bd20b Support profiling based on linux kernel performance events. 
Since 2.6.31 perf_events interface has been available in the
kernel. There's a nice tool called "perf" (linux-2.6/tools/perf) that
uses this interface and provides capabilities similar to oprofile. The
simplest form of its usage is just dumping the raw log (trace) of
events generated by the kernel. In this patch I'm adding a script
(tools/ll_prof.py) to build profiles based on perf trace and our code
log. All the heavy-lifting is done by perf. Compared to oprofile agent
this approach does not require recompilation and supports code moving
garbage collections.

Expected usage is documented in the ll_prof's help. Basically one
should run V8 under perf passing --ll-prof flag and then the produced
logs can be analyzed by tools/ll_prof.py.

The new --ll-prof flag enables logging of generated code object
locations and names (like --log-code), and also of their bodies, which
can be later disassembled and annotated by the script.

was efficiently unused.

However, it may trigger spurious out of memory exceptions if requested

d4bc8e1585 New Heap profiler: add dumping HeapNumbers and InternalFields to snapshot. 
HeapNumbers do consume memory, so it's worth dumping them. However, we
don't dump their values, as they are not as self-descriptive as values
of strings, and they will increase snapshot size. Storing heap numbers
values can be added if we will feel a sufficient demand for that.

InternalFields are used, e.g. for storing references to DOM nodes
event handlers.

65edae5b62 Fix a bug in our handling of conditional expressions in test contexts. 
In the FullCodeGenerator, we compile the true subexpression of a
conditional (ternary) expression in the inherited context of the
entire expression.  This is correct for effect and value contexts, but
not for test contexts where the context includes a possible
fall-through label.

bef3ae07db Begin a more aggressive refactoring of the Compiler interface. 
The plan is to use the CompilationInfo class to communicate inputs and
outputs to compilation pipeline phases, which each return a boolean
success/failure flag.

The intent is to make it easier to compose small pieces of the
pipeline without having to grow a custom function each time, each
taking a half dozen arguments.

This change modifies the very front end (the parser).

1156bbc82a Fine-tune inobject slack tracking. 
The current parameters (initial slack = 6, kGenerousAllocationsCount = 16)
caused 15-20% performance regression on 3d-raytrace on x64 
(visible both in standalone shell and in the web harness). This is very
likely some kind of an alignment  problem (it goes away completely with --prof).
A similar problem can be observed on ia32 with initial slack=2.

Increased initial slack to 8 and decreased constructions count to 8. 
This made the regression go away (and did not harm any of the other tests).

Use a macro to generate the definition of node_type as well as Accept

589eb4a861 Add CODE_POINTER_ALIGN, use it in Page to align generated code. 
The object's space in Page starts after Page header and is aligned to kMapAlignment which is 32 bytes on 32-bit and 8 bytes on 64-bit.

In case of 64-bit target, the current page header size is exactly 32 bytes so we get the code magically aligned at 32 bytes but it is better to have a separate CODE_POINTER_ALIGN macro to make sure the object space in Page is aligned properly for both maps and code.

There could be a small waste of bytes sometimes (since both Page header and Code header sizes are aligned separately) but it seems the optimal one would involve cross-dependencies between .h files and not clear if it's worth it.

This is a back-port from Isolates branch.

cfbc1eed9c Prevent modification of cached normalized maps. 
Finally sovles the problem that r5342 attempted to solve.
When adding a stub to a map's code cache we need to make
sure that this map is not used by object that do not need
this stub.

Existing solution had 2 flaws:
1. It checked that the map is cached by asking the current context.
If the object escaped into another context then NormalizedMapCache::Contains
returns false negative.

2. If a map gets evicted from the cache we should not try to modify it
even though Contains returns false.

This patch implements much less fragile solution of the same problem:
A map now has a flag (is_shared) that is set once the map is added
to a cache, stays set even after the cache eviction, and is cleared
if the object goes back to fast mode.

Added a regression test.

For some reason, the scope's arguments and arguments shadow were
variable proxies, which resulted in all references to the arguments
shadow being shared in the AST.  This makes it hard to put per-node
state on the AST nodes.

I took the opportunity to remove Variable::AsVariable which has
confused people in the past, and to rename Variable::slot to the more
accurate Variable::AsSlot.

06c867404b Dynamically determine optimal instance size. 
The number of inobject properties used to be derived from the number
of this property assignments in the constructor (and increased by 2 to
allow for properties added later). This very often leads to wasted inobject 
slots.

This patch reclaims some of the unused inobject space by the following method:
 - for each constructor function the first several objects are allocated using the initial 
   ("generous) instance size estimation (this is called 'tracking phase').
 - during the tracking phase map transitions are tracked and actual property counts are collected.
 - at the end of the tracking phase instance sizes in the maps are decreased if necessary
   (starting with the function's initial map and traversing the transition tree).
 - all further allocation use more realistic instance size estimation.

Shrinking generously allocated objects without costly heap traversal is made possible 
by initializing their inobject properties with one_pointer_filler_map (instead of undefined). 

The initial slack for the generous allocation is increased from 2 to 6 which really helps some tests.

ceb9d79d73 Generate inline code for contextual loads. 
Contextual load requires only a map check followed by a cell hole
check so we can generate pretty compact code for that. The fact that
we have inlined code is marked by mov ecx, offset instruction after
the IC call. Inlining is only enabled inside loops and in non-builtin
functions.

The generated code size increase is about 3%. This descreased the
pc-to-code cache hit rate in some of the benchmarks that trigger
GC. To compensate we now have 4 times as much entries in the cache.

It turns out they were filtered out. But when I unfiltered them, I
discovered another issue: when DevTools run, regexp literals get
recompiled each time they called (looks like this is concerned with
switching to full compiler), so I ended up having multiple entries for
the same regexp. To fix this, I changed the way of how code entries
equivalence is considered.

eef3bd7c04 Prevent inline constructor generation when duplicate properties are present in the constructor. 
Currenly the constructor like this:
function f() {
  this.a = 0;
  this.a = 1;
  this.a = 2;
}
creates a map with duplicate desciptors which is bad in many ways.

187d249d92 Enhance SafeStackFrameIterator to avoid triggering assertions in debug mode. 
When running profiling in debug mode, several assertions in frame
iterators that are undoubtedly useful when iterator is started from a
VM thread in a known "good" state, may fail when running over a stack
of a suspended VM thread. This patch makes SafeStackFrameIterator
to proactively check addresses and bail out from iteration early,
before an assertion will be triggered.

240cee91e4 Add support for near labels. 
This change introduces near labels in the assembler, allowing us to
uptimize forward jumps (conditional and unconditional) if we can
guarantee that the jump is witin range -128 to +127.

I changed a large fractions of the existing Labels to NearLabels, and
left out cases where it was not immediately clear if it could be used
or not (not immediately clear means labels covering a large code
block, or used in function calls which we could potentially change to
accept near labels).

2388079051 Implement heap snapshots serialization into JSON. API is designed 
to avoid storing serialized snapshot on VM, instead it is emitted
using output stream interface.

The size of JSON emitted is roughly equal to used heap size
(when stored as an ASCII string).

Now a whole heap snapshot can be serialized and transmitted outside
VM. This makes possible:
  - implementing non-async UI for heap snapshots inspection;
  - storing heap snapshots for further inspection;
  - remote profiling (we can even implement a snapshotting mode
    where a snapshot isn't even stored in VM, only transmitted --
    good for mobile devices);
  - creating tools for outside heap snapshots processing, e.g.
    converting to HPROF.

62f7cd8500 Handle argument conversion in StringAddStub. 
In case one of the arguments is known to be a string we emit a few
fast conversion attempts for the other.  This allows using the
StringAddStub instead of STRING_ADD_{LEFT,RIGHT} builtins.

d3e457303e Add API callback for tracking allocated memory 
Allows the host application to provide a mechanism for notification and custom logging through a callback (set through the API V8::AddMemoryAllocationCallback and removed through V8::RemoveMemoryAllocationCallback), when V8 allocates ro frees memory. 

This replaces the current histogram data "V8.ExecutableMemoryMax" by allowing usage data to be logged by the application as required rather than always through V8. 

BUG=http://crbug.com/54222
TEST=Set the callback function with the API and cause V8 to allocate memory.

That could improve chances for commit success as currently,
if we moved free pages out of order, we cannot shrink spaces.
However, when we experience problems commiting from space back, we should
use most of resources at our disposal.

be5763fc4d Cleanup the way the debugger stores live registers when entering at a break 
The live registers are now only stored to the expression stack with the non pointer values being stored as smis (on the 32-bit platforms these values are assumed to be 31-bit max).

This makes the CEntryStub entry/exit code much simpler, and there is no longer any need for a mode (debug or normal) on it.

Fix a missing live register when breaking at ARM keyed load.

7672338bc9 Fixes bug in Object.freeze and Object.seal causing them to misbehave when Array.prototype has changed. 
Object.freeze and Object.seal uses GetOwnPropertyNames which
returns an array with local property names. This array will also have
the additional properties defined on Array.prototype or
Object.prototype.

Note that, the implementation of GetOwnPropertyNames (when used as
Object.getOwnPropertyNames) is correct, since the spec says to create
a new Array (which would also have these properties).

r5147 wrongly assumed that a code cache for a slow case map is always empty.
This patch solves this: whenever we attempt to add a stub to a map's code cache 
we check that this map is cached. If it is we give the object its own copy
of the map and only then modify the map.

82309445ad Move code stub implementations from codegen-[platform].cc files to new code-stub-[platform].cc files, and declarations to new code-stub-[platform].h files. 
Remaining work is to do the same for platform-independent code stub declarations, and to remove all dependencies on codegen header files from code stub files.

99ce72bd8a Use collector for preparse data. 
This is in preparation of adding more data to the preparse record.
Using a collector instead of a list avoids copying data when the backing
store grows.

b1e27e2cd5 Created collector class and used it to collect identifiers during scanning. 
The collector class automatically expands to hold the values added to it,
like a List, but doesn't ensure that the backing store is contiguous, which
allows it to avoid copying back and forth as the buffer grows.

This is in preparation for identifyng identical symbols during preparsing.
