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.

crash if a gc is triggered by setting the scopeinfo in CompileLazy. If
this gc triggers code flushing the compiled function could be flushed,

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.

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

Since out internal representation of a property descriptor does not have configurable and writable

This change makes use of the right method calls on our internal representation (isWritable() and
isConfigurable()). Tests added directly to the mjsunit test.

Use the number of in-object properties when deciding how many fast

properties to allow on an object. If there are many in-object
properties it is unlikely that the object is used as a dictionary and
we allow more map transitions to keep such objects in fast case.

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.

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.

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.

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.

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.

Custom call IC-s for String.prototype.{charAt,charCodeAt}.
...
These string methods can be composed from two basic blocks: charCodeAt
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.

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.

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.

- 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

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().

Add complete implementation of full compiler for the ia32 architecture
...
This makes the full compiler handle all constructs on ia32. However the syntax checker for the full compiler is still the same so for both normal operation and with the flag --always-full-compiler the coverage of the full compiler will be the same.
This is on preparation for improving the debugger break point experience where the plan is to only use code from full code generator when debugging JavaScript.
Runs all tests on all three platforms in release and debug mode. The tests also run with both the following flags to the test runner
--special-command="@ --nofull-compiler"
--special-command="@ --always-full-compiler"
The changes to the x64 and ARM architectures are mainly structural due to the change to EmitVariableAssignment to handle initialization of const variables.

CPU profiler: add secure profiles by filtering out functions using security tokens.
...
As several pages can run in a single V8 instance, it is possible to
have functions from different security contexts intermixed in a single
CPU profile. To avoid exposing function names from one page to
another, filtering is introduced.
The basic idea is that instead of capturing return addresses from
stack, we're now capturing JSFunction addresses (as we anyway work
only with JS stack frames.) Each JSFunction can reach out for
context's security token. When providing a profile to a page, the
profile is filtered using the security token of caller page. Any
functions with different security tokens are filtered out (yes, we
only do fast path check for now) and their ticks are attributed to
their parents.

ARM: Pass arguments to keyed store IC in registers
...
The calling convention for keyed store IC on ARM is changed to receive the arguments value, key and receiver in registers r0, r1 and r2 instead of on the stack. When calling keyed store IC with a virtual frame the arguments are passed through the virtual frame and consumed by the call.
Changed the register usage in the IC code to postpone spilling the registers holding value, key and receiver to the stack until making a call into the runtime system.
Runs all the tests with:
--special-command="@ --nofull-compiler"
--special-command="@ --always-full-compiler"
--special-command="@ --noenable-vfp3"

ARM: Fix generating two ldr instructions in place of ldrd.

When ldrd is not available two ldr instructions are generated. This fixes these in the case where the register used in the memory operand is the same as the first register in the register pair receiving the values.
All tests now run on ARM with the flag --special-command="@ --noenable-vfp3". Running without VFP3 support in the simulator causes more ldrd instructions to be used, and the default build configuration does not utilize ldrd, but generated tow ldr instructions.

Allow build-time selection between ia32 and x86_64 in the GYP/Xcode Mac

Chromium build.
v8.gyp no longer sets any V8_TARGET_ARCH_* macro on the Mac. Instead, the
proper V8_TARGET_ARCH_* macro will be set by src/globals.h in the same way as
the V8_HOST_ARCH_* macro when it detects that no target macro is currently
defined. The Mac build will attempt to compile all ia32 and x86_64 .cc files.
#ifdef guards in each of these target-specific source files prevent their
compilation when the associated target is not selected. For completeness,
these #ifdef guards are also provided for the arm and mips .cc files.

due to ecx increment, but I didn't check this hypothesis.) The next thing
to try could be direct jump into right place of long sequence of stos'es.

First step towards making JumpTarget work on ARM. Instead
...
of having a list of virtual frame pointers in the jump
target we have one virtual frame, which is the frame that
all have to merge to to branch to that frame. The virtual
frame in the JumpTarget is inside the JumpTarget, rather than
being an allocated object that is pointed to. Unfortunately
this means that the JumpTarget class has to be able to see
the size of a VirtualFrame object to compile, which in turn
lead to a major reorganization of related .h files. The
actual change of functionality in this change is intended
to be minimal (we now assert that the virtual frames match
when using JumpTarget instead of just assuming that they do).

Correct issue 696 with Date.parse returning a value when called on a non date string.
...
The error was introduced in revision 4557 where support was added for
ES5 date time format strings. Because there was no check for a valid
year a random string starting with a non-digit character would be
parsed.
This change disallows ES5 formatted dates where there is no date
fraction (i.e., with only a timestamp). Since none of the other
browsers support Date.parse on only timestamps I have disabled this
totally instead of just correcting the parser.

Refactor assignment in the ARM code generator
...
This is mainly a port of r3899. It also adds handling of initilization blocks in ARM which had no special handling before.
The "calling conventions" used for
EmitNamedLoad
EmitNamedStore
EmitKeyedLoad
EmitKeyedStore
are somewhat mixed, but will become more aligned as the use of register allication and passing of argument in registers to IC's is extended.

Inline keyed load on ARM

This uses the same infrastructure as is used by the inlining of named property load. The code patching if the inlined code is simpler as the key is provided in a register os the only patching required is the map check directing the inlined code to the deferred code block or not.

Avoid constant pool blocking for too long
...
The generation of the deferred code for named property load where the load was inlined did a constant pool blocking for the whole deferred code. Having large numbers of this type of deferred code generated one ofter the other effectively blocked the constant pool for all the deferred code causing
Removed the BeforeGenerate/AfterGenerate for the deferred code and made macro assembler StartBlockConstPool/EndBlockConstPool non-public. Re-introduced BlockConstPoolFor instead to use with BlockConstPoolScope to block some more instructions cross function calls.
Also handle the use of native code counters for inlined named property load.

Don't share function result caches between contexts.
...
A reference to the caches array was embedded directly into the builtin
code and this allowed sharing objects between contexts.
Unfortunately, clearing the cache on GC won't prevent sharing so we
either have to have per-context builtin code or load the cache
indirectly from the current context. This change implements the second
approach. The first approach may be interesting to consider in the
future for some perfomance critical functions, and the current
approach can still be improved by putting the caches directly into the
global context (or even global objects).

String keyed load used to call STRING_CHAR_AT builtin that performs
two steps (get a char code, construct a one-char string from the
code), both of which have fast cases implemented as inline runtime
functions. In this chage most of the code from these functions is
extracted to a set of common generator functions in StringStubBase and
the fast cases are grouped together in the IC code.

Inline fast cases in string keyed load IC.
...
String keyed load used to call STRING_CHAR_AT builtin that performs
two steps (get a char code, construct a one-char string from the
code), both of which have fast cases implemented as inline runtime
functions. In this chage most of the code from these functions is
extracted to a set of common generator functions in StringStubBase and
the fast cases are grouped together in the IC code.

actual sampling ticks count.

Reapply load ICs for nonexistent properties.
...
We need to be careful to check global property cells for the property
encountered during lookup. Therefore, the ICs have to be specific to
the name of the property if global objects are involved. In
principle, this means that we could get a large number of monomorphic
ICs for the same map if there is a global object in the prototype
chain. However, since this is only done for normal load ICs and not
for keyed load ICs I do not expect this to be a problem. I will
experiment with it once this goes in.

Allow new CPU profiling subsystem to coexist nicely with the old one.
...
This is to make possible enabling usage of the new profiling subsystem
in Chromium without much hassle. The idea is pretty simple: unless the
new profiling API is used, all works as usual, as soon as Chromium
starts to use the new API, it will work too.

Simple register allocation for ARM. Only top of expression
...
stack for now. Next step is probably fixing the binary
op stubs so they can take swapped registers and fixing
the deferred code so it doesn't insist that all registers
except the two operands are flushed. Generates slightly
worse code sometimes because the peephole push-pop
elimination gets confused when we don't use the same
register all the time (the old code used r0 always).

C++ profiles processor: align browser mode with the old implementation, sample VM state.

In browser (DevTools) mode, only non-native JS code and callbacks are reported.
Also, added "(garbage collector)" entry which accumulates samples count in GC state.
Trying to display "(compiler)" and "(external)" only brings confusion,
because it ends up in displaying scripts code under "(compiler)" node, and DOM
event handlers under "(external)" node, which looks weird.

Move the AstVisitor stack check from Accept to Visit.
...
The stack check has been moved from the Accept function dispatching on
the AST node type, earlier to the Visit function dispatching on the
visitor type.
This allows very simple non-recursive visitors (not taking extra
arguments or returning values) via the convention of calling "Visit"
if one wants the stack check and "Accept" if one does not. Recursive
calls should all be via "Visit".

Rework flow graph construction.
...
The flow graph has been simplified to remove the special branch, join,
and exit nodes. All nodes are now basic blocks (possibly empty to
preserve edge-split form) with a distinguished entry and exit block.
Most trivial expressions are not added to the flow graph as
instructions. The assigned variable analyzer has been changed to
sometimes work right-to-left so that right subexpressions can be
marked as trivial.
The reaching definitions analysis has been temporarily removed, and
the analyses that depended on it (primitivity analysis, dead code
marking) as well.

Store type information with constants.
...
Instead of testing the value of a constant frame element to determine
the type we compute its type information at construction time.
This speeds up querying the type information during code generation.
This change also adds support for Integer32 constants and sets
the type information accordingly.

Expose debug context into the native code. This change is doing several things:
...
1) Exposes Local<Context> v8::Debug::GetDebugContext().
Rationale: We can already get debugger context instance using various workarounds,
so exposing it explicitly in the API only makes things more clear.
2) Removes debugger.HasJavaScriptFrames() requirement for entering debugger context.
Rationale: Sometimes we'd like to call into debugger from the external native code.
3) Makes Debugger v8::Debug::Call execute on debugger context's global object.
Rationale: This is somewhat arguable, but temporary measure. We've agreed that we
should introduce a DebugAPI object that would expose necessary API in the debug-delay.
The problem is that it would take some time to define this API and it is not really
convenient to do that on the v8 land given the difference in v8 / host lifecycle.
The plan is to compose this API as a Debug.* wrapper outside v8 by means of exposing
debugger context's global object here, and once API settles down, upstream it to v8 and
start making Debug::Calls on this new DebugAPI object instead.

Inline floating point compare
...
Inline floating point compare instead of calling the stub when the following conditions are met:
* Code is in a loop
* Compare is not a for loop condition
* Compare is not an equal comparison
This inlined code handles heap number to heap number and heap number to smi compare. It can also handle smi to smi compare, but whenever there is a chance of comparing two smis the smi compare is inlined before the inlined floating point compare. Support for non SSE2 hardware is included.
A new set of variants of the compare stub without the floating point comparison code is called if the inline comapre fails due to the operands not beeing heap numbers or smis.
The virtual frame has been extended with a branch taking two live results to be carried through to the destination. This makes this change much simpler as the inlined code have two live results in registers and a number of bailouts.
CompareStub::GetName needs to be updated as well. I will do that as a separate change.
Also inlined equality check if both operands can't be NaN. This can only provide positive equals if it is the same object.
