9c503a8330 Fix some inconsistent formatting. 
I noticed we sometimes had extra spaces before and after the "const"
keyword.  Probably the result of a search and replace gone wrong.

This is a whitespace only change.

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.

830185b175 Clean up some messiness in Scopes. 
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.

c1903ce332 Show RegExp calls in the profile. 
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.

This change introduces near labels in the assembler, allowing us to

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.

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.

This removes the expected failure of a mozilla test that we now pass
(an empty array is returned if Array.splice is called with no
arguments) and fixes debug check failure by allocating a new empty
array using AllocateEmptyArray if splice is called with zero arguments
(makes sure we can always create a handle).

19dc35c13f Force relinking of paged space if first attempt to recommit from space fails. 
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.

Also get rid of currently unused parameter to DeallocateFunction.

3fb62235e3 Add functionality for finding code objects from a pc that points into 
the code object's instructions.

This allows us to find a code object using just the pc. This approach
uses a cache (PcToCodeCache) to make sure we don't continuously have
to iterate heap pages.

This change eliminates the need for cooking and uncooking of stack frames.

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.

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).

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.

3202df6c69 Copy-on-write arrays. 
Object model changes
----------------------------------------
New fixed_cow_array_map is used for the elements array of a JSObject
to mark it as COW. The JSObject's map and other fields are not
affected. The JSObject's map still has the "fast elements" bit set. It
means we can do only the receiver map check in keyed loads and the
receiver and the elements map checks in keyed stores. So introducing
COW arrays doesn't hurt performance of these operations. But note that
the elements map check is necessary in all mutating operations because
the "has fast elements" bit now means "has fast elements for reading".
EnsureWritableFastElements can be used in runtime functions to perform
the necessary lazy copying.

Generated code changes
----------------------------------------
Generic keyed load is updated to only do the receiver map check (this
could have been done earlier). FastCloneShallowArrayStub now has two
modes: clone elements and use COW elements. AssertFastElements macro
is added to check the elements when necessary. The custom call IC
generators for Array.prototype.{push,pop} are updated to avoid going
to the slow case (and patching the IC) when calling the builtin should
work.

COW enablement
----------------------------------------
Currently we only put shallow and simple literal arrays in the COW
mode. This is done by the parser.

8e0cd6db8a Handle overwriting valueOf on String objects correctly when adding 
This adds a check to the fast case string add to ensure that the String object still have the default valueOf function. The default valueOf is sitting on a hidden prototype of String.prototype.

Before using the fast case valueOf the object is checked for a local valueOf property. For slow case objects this check always reports true (the dictionary is not probed, so valueOf might be there) and for fast case objects the descriptor array is checked for the valueOf symbol (just liniar scan). After that the prototype is checked for beeing the initial value of String.prototype. If this all pass (that is the default valueOf is still in place) this result is cached on the map making the check fast the next time.

This is only implemented in the optimizing compiler, as the two usages of %_IsStringWrapperSafeForDefaultValueOf is never hit by the full compiler.

I will port to x64 and ARM when this has been reviewed for ia32.

I will remove the performance counters prior to final commit.

36e5743674 Put direct code pointers into JSFunction objects. This is a first step 
in allowing more flexible compilation and to simplify builtins lookup. 

This changes a number of places where code objects are assigned to
SharedFunctionInfo objects to also assign this code object to the
JSFunction. In addition, the code flushing is changed slightly to
accomodate this (we need to flush the code from functions pointing to
SharedFunctionInfo objects that has already been flushed).

57769489d5 First phase of migration to new indexed property query callbacks. 
Eventually indexed property query callbacks will return attributes
(as an integer) or an empty handle if property is not intercepted.

To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK
macro would control if old or new style API is used.

So the migration plan is:

1) introduce new API which should be explictily enabled;
2) switch to new API defining USE_NEW_QUERY_CALLBACK before
include of <v8.h> (that would require changes to client code as well)
3) remove old API from v8
4) remove #define USE_NEW_QUERY_CALLBACK from clients.

3377349a51 Support object literal map caching for literals with keys that are array indices. 
The caching code used to require that all keys in the literal were symbol strings
in order to be able to cache object literal maps.

Relaxed this requirement to allow array indices as well (as in { "1": "one", two: "two" }).

Changed the way 'number_of_properties' is calculated so that redundant property slots are not
allocated for array indices.

2a877bfc95 Landing for pmehta. 
Changed a static cast from static_cast<int> to static_cast<size_t>
that previously introduced a signed/unsigned comparison issue in the
main allocator for V8 (MemoryAllocator::AllocateRawMemory) that could
be used to bypass the V8 allocation limitations or trigger integer
overflows.

5caa11dafb Reorder SharedFunctionInfo setup in lazy compile, quick fix for crbug.com/49099 
This fixes issue 49099 (http://crbug.com/49099) that makes chromium
crash if a gc is triggered by setting the scopeinfo in CompileLazy. If
this gc triggers code flushing the compiled function could be flushed,
causing the ASSERT(shared->is_compiled()) to fail. By reordering the
two methods we make sure that no allocation happens before the end of
the method.

4957326521 Refactor type checks in v8natives.js and runtime.js. 
This includes adding a new inline IsSpecObject method to the code
generator.  The old approach was somehow ineffecient since we would
call both IsObject, IsUndetectable and IsFunction to determine if
something was an object according to the spec. This change introduces
a new macro that determines if something is an object according to the
spec (and this does not include null). 

This change also corrects a few places where undetectable objects was
not allowed even when they should be (priorly they would use only
IS_SPEC_OBJECT_OR_NULL, which would return false on an undetectable
object, the new IS_SPEC_OBJECT returns true on an undetectable object.

c98ac6e82c Heap profiler: implement diffing of snapshots. 
To trace objects between snapshots, an external map of object tags is
maintained. After the first heap snapshot has been taken, the map is
updated by reporting object moves from the GC. If no snapshots were
taken, there is no overhead (except for flag checking).

I considered graph comparison algorithms that doesn't require using
object tags, but they are all of a high computational complexity, and
will still fail to detect object moves properly, even for trivial
cases, so using tags looks like unavoidable.

118a421067 Simplify the transitions in the Binary Op ICs. Now a single call 
to the runtime will both patch in the more specialized binary op
stub and calculate the answer.  This eliminates the need to call
both the rest of the binary op and the patching runtime call.  The
runtime routines are altered to be more agressive in returning
Smis so we don't get spurious heap numbers as inputs to binary ops
while we are patching the binary op ICs.

8ab6832203 Add "has fast elements" bit to maps and use it in inlined keyed loads. 
A potential issue with this change is creating lots of maps when
objects flip between fast/slow elements modes.  We could add special
transitions to avoid this.  Yet testing this on our benchmarks, gmail,
and wave seems to indicate that this is not a real problem.

ae39e059c2 Take survival rates of young objects into account when choosing old generation limits. 
Stable high survival rates of young objects both during partial and
full collection indicate that mutator is either building or modifying
a structure with a long lifetime.

In this case we aggressively raise old generation memory limits to
postpone subsequent mark-sweep collection and trade memory space
for the mutation speed.

927750571c Remove redundant checks in and around GenerateDictionaryLoad. 
Similar or duplicate checks are scattered around the code before doing the dictionary load. 
Also the entire branch in GenerateCallNormal that handles global/builtin receiver is 
guaranteed to bail out from GenerateDictionaryLoad, so there is no point in generating it at all.

The purpose of the patch is:
- making C++ code more compact and transparent,
- not generating dead code. 

There is a tiny performance gain. The patch is ia32 only for now.

Please tell me if I am missing anything.

e045ca6898 Better handling of stepping out of a function 
With the change in r4820 all return statements are now breakable like any statement, so stepping will stop before the return statement actually returning from a function. With this change the position when breaking in the function return (after executing the return statement) will be the actual end of the function. At this point the return value is available as it saved to the stack by the debug break at return handling. Added information on the actual value returned from the function to the debugger.

634fb9152c More precise break points and stepping when debugging 
Added support for more precise break points when debugging and stepping. To achieve that additional nop instructions are inserted where breaking would otherwise be impossible. The number of nop instructions inserted are sufficient to make place for patching with a call to a debug break code stub. On Intel that is 5 nop's for 32-bit and 13 for 64-bit. Om ARM 3 nop instructions (12 bytes) are required.

In order to avoid inserting nop's in to many places a simple ast checker have been added to check whether there are breakable code in a statement or expression. If it is possible to break in an expression no additional break enabeling code is inserted.

Added break locations to the true and false part of a conditional expression.

Added stepping tests to cover more constructs.

These changes are only in the full compiler.

Changed the default value for the option --debugger in teh d8 shell from true to false. The reason for this is that with --debugger turned on the full compiler will be used for all code in when running d8, which can be unexpeceted.

12f6306420 First phase of migration to new named property query callbacks. 
Eventually named property query callbacks will return attributes
(as an integer) or an empty handle if property is not intercepted.

To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK
macro would control if old or new style API is used.

So the migration plan is:

1) introduce new API which should be explictily enabled;
2) switch to new API defining USE_NEW_QUERY_CALLBACK before
  include of <v8.h> (that would require changes to client code as well)
3) remove old API from v8
4) remove #define USE_NEW_QUERY_CALLBACK from clients.

ebba43f37a Make intercepted properties retrievable only by getter to be not enumerable. 
Currently if there is no query callback, V8 finds out intercepted properties'
attributes using getter: if getter returns not empty handle V8 treats
such a property as property with NONE attribues which means this property
is enumerable.

However, if there is no enumerator, this property cannot be enumerated.
Thus I think we should treat such properties as not enumerable.

Drawback of this approach is now one has to implement both query and enumerator
callbacks to implement enumerable intercepted properties.

we always default configurable, writable, enumerable to true (we don't have
PropertyDetails for fast elements).

A few new tests are added to get-own-property-descriptor.js, I will

and fromCharCode, both of which have fast cases for certain types of
inputs. In this patch these two blocks are refactored to allow
generating the fast cases without having to jump around the slow
cases. In the slow cases since they can now be invoked both from
inline runtime functions and from IC stubs we either have to
save/restore state of the current frame or enter/leave a new internal
frame. This is handled by new RuntimeCallHelper interface. Its
implementation for virtual frame is based on FrameRegisterState class
extracted from DeferredCode class.

3e88d0d2af Various refactorings in interceptor calling and loading. 
1) do not push receiver early---that simplifies tail call preparation
on ia32/x64 and renders special cleanup unnecessary;
2) do not do second map check if interceptor's and cached holder
are the same;
3) do not push/pop receiver if receiver and holder registers are the same
(means that receiver is interceptor's holder);
4) do batch pushes on arm;
5) minor cosmetic improvements.

6de39cd1f0 ARM: Add Ldrd/Strd to the macro assembler 
The macro assembler now checks for ARMv7 support and generates instructions for Ldrd/Strd accordingly. INstructions ldrd/strd in the assembler requires ARMv7 support enabled. This removes the a check for CAN_USE_ARMV7_INSTRUCTIONS making the ARMv7 support in the simulator fully controled by the --enable-armv7 flag.

95939ada29 Fix issue 720 making Object.defineProperty handle existing writable flags correctly. 
The existing version will overwrite the existing writable flag with
false even in the case where no new value is given and the existing
writable flag is true.

The reason for the issue is that there is no check to see if the
provided descriptor actually has a writable attribute. This causes us
to use the default value (false) even in the case where nothing was
provided. In addition, the existing tests makes wrong assumptions (that writable is always set to false if not provided) and has been changed to follow the specification.

22e4847fde ARM: Update the full compiler to handle all code 
The full compiler is now complete on ARM as well. The syntax checker is still used to determine whether to use it for top level code or not during normal execution. When debugging is enabled all code will be compiled with the full compiler.

This change removes the temporary flag --force-full-compiler and now the flag --always-full-compiler enables the full compiler for all code on all platforms.

This also fixes building on Intel platform without debugger support (ENABLE_DEBUGGER_SUPPORT not defined) and adds full check for the full compiler for lazily compiled code.

675e711f1c Cardmarking writebarrier. 
- New сardmarking write barrier handles large objects and normal objects in a similar fashion (no more additional space for pointer tracking is required, no conditional branches in WB code).
- Changes to enable oldspaces iteration without maps decoding:
-- layout change for FixedArrays: length is stored as a smis (initial patch by
Kevin Millikin)
-- layout change for SharedFunctionInfo: integer fields are stored as smi on
arm, ia32 and rearranged on x64.
-- layout change for String: meaning of LSB bit is fliped (1 now means hash not
computed); on x64 padding is added.
-- layout of maps is _not_ changed. Map space is currently iterated in a special
way.

897f7dedc1 Allow to define accessors on objects. 
Currently one can only define accessors on object templates.  This patch
allows to create accessors on the fly.

These accessors could control access to elements as well.  This element
support is somewhat rudimentary and may require future work (for example,
we probably don't want to convert index into a string.)

Noticing that the only difference between samevalue and strict equality is on

The old version did not return a correct answer if called on two strings since 
StringEquals (from runtime.cc) returns an answer that is the negated value 
(if treated as a boolean).

ab6055d85d Landing patch by tonyg@chromium.org: 
Changing ScriptData API to serialize its internal representation to a
const char* array.

This decouples the API from the internal representation and avoids the need for
callers to serialize themselves.

As a side-effect, ScriptData::New() no longer assumes ownership of its input.
This shouldn't matter as typical usage patterns for the old API would have
required a copy prior to calling ScriptData::New().

Object.defineProperty with empty property descriptor.

The issue is fixed by implementing step 5 and 6 from DefineOwnProperty in the

This also fixes a bug in SameValue when used on boolean values (it
would priorly return a number - not a boolean).
