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.

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.

Add a V8 specific target architecture to the GYP file
...
The V8 GYP file now uses its own target architecture. It default to the standard target_arch, but can be set to a separate value. E.g. using
export GYP_DEFINES="target_arch=ia32 v8_target_arch=arm"
makes it possible to have the V8 ARM simulator be used in a IA32 build.
Added some checking of supported host/target architecture combinations.

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).

Changed inlined property load detection on ARM
...
Instaed of having a nop after all non-inlined calls to load IC use a different nop (mov r1, r1 instead of mov r0, r0) to detect an inlined load IC.
Added more infrastructure to the deferred code handling to make it possbile to block constant pool emitting in a deferred code block, including the branch instruction ending the deferred code block.
Addressed a couple of comments to http://codereview.chromium.org/1715003 , including adding an assert to make sure that the patching of an ldr instruction is always possible.

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

Report approximated duration in milliseconds for profile nodes.
...
The simple formula "ms = ticks * sampler_interval" doesn't work,
because e.g. on Linux, the actual sampling rate can be 5 times
lower than the one set up in the code. To calculate actual sampling
rate, current time is periodically queried and processed along with
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.

Ensure stack alignment in ARM port
...
In the CEntryStub keep track of the actual skew from the correct alignment to ensure proper alignment before calling the runtime. Add checks to test the expected skew when running on hardware.
Use the PrepareCallCFunction/CallCFunction in a few other places.
Add check to the ARM simulator for correct alignment.
Add option --sim-stack-alignment to set the stack alignment in the simulator. Currntly only values 4 and 8 makes sense. 8 is the default to make snapshots generated with the simulator work on hardware requiring 8 byte stack alignment.

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.

The stack check has been moved from the Accept function dispatching on

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".

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.

Some string optimizations:
...
* Faster hashing for sequential strings.
* When adding short external two-byte strings try to convert them
back to ascii. Chances are high the embedder uses two-byte
representation even for ascii strings. This optimization saves

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.

Fix bug when generating a fast smi loop.
...
We may encounter an invalid frame after generating code
for the loop body in case the loop body ends in an unconditional
return. Before setting the type information for the loop variable
we need to check for a valid frame.

String search performance improvements:
...
* Using memchr for first/only char lookup is faster than hand-coded
loop. It processes one machine word per iteration so it helps even
more on x64.
* Tweaked badness computation in simple search. We pay only for the
first char memchr scans, not for all of them.

Also: two small changes to flow graph printing. Children of branch

destroy AST node number before printing (it's useful to print the
definition).

Add an assigned variables analysis.
...
This change adds a pass over the AST that computes the
set of assigned variables for locals and parameters for each expression.
The result of this analysis is used to for two purposes:
1. Recognize variables that are trivial subexpressions. A left sub-expression
of a binary operation is trivial if it is a local variable or a parameter
and it is not assigned in the right sub-expression. In the case of a
trivial left sub-expression we evaluate the right first.
Currently only binary operations and compare operations are considered
when finding trivial left sub-expressions.
2. Recogize certain simple for-loops with a constant trip count where the loop
variable is always within smi range. If the loop count variable is not
assigned in the body of the loop (except in the update expression the
for-loop). This allows omitting smi checks on operation using the loop
count variable.

Refactor the code cache to handle large number of properties on the global object (take 2).
...
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.
The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.
This is a remake of r3952 (http://codereview.chromium.org/652119 ) which have the additional ability to look for the index of code stubs for access to the global object.

Correct handling of adding a string and a smal integer

The fast case of looking up the string convertion of the smi did not handle the case where left/reghe operands could be in eax/edx instead of edx/eax which is the default.

Small simplification of #include dependencies.
...
Remove messages.h from v8.h and include it explicitly in only the few places
it is needed. Many files relied on getting handles-inl.h implicitly from
messages.h through v8.h, so include handles-inl.h explicitly in v8.h
instead.
Remove zone-inl.h from header files where it is not needed, can be replaced
by a forward declaration, or can be replaced by zone.h (specifically,
factory.h and heap.h). Include zone.h or zone-inl.h in header files where
it was implicitly included via heap.h or factory.h. Prefer zone.h over
zone-inl.h in header files where possible by including zone-inl.h in .cc
files.

Initial implementation of an edge-labeled instruction flow graph.
...
The flow graph is built by walking the AST. Edges are labeled with
instructions (AST nodes). Normal nodes have a single predecessor edge and a
single (labeled) successor edge. Branch nodes are explicit, they have a
single predecessor edge and a pair of (unlabeled) successor edges. Merge
nodes are explicit, they have a pair of predecessor edges and a single
(unlabeled) successor edge.
There is a distinguished (normal) entry node and a distinguished (special)
exit node with arbitrarily many predecessor edges and no successor edges.
The graph is intended to support graph-based analysis and transformation.

Refactor the scanner interface
...
No need to create sub strings for lazy compiles. The scanner will start from the start position provided.
Moved the creating of character streams into the scanner where possible. This uses a input buffer in the scanner class instead of a stack allocated one.
Added a UTF16 buffer for reading external ascii strings (by templating the external two byte string one) as all the source for the builtins are exposed as external ascii strings.

Refactor the code cache to handle large number of properties on the global object.
...
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.
The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.

Begin using a list of bailouts instead of a singleton in the fast code generator.

A list of bailout descriptions is kept in the CompilationInfo
structure that is shared between the primary and secondary code
generators. The primary adds a description to the list for each
bailout position.
Responsibility for binding labels is moved from the primary to the
secondary code generator. All the labels still target the start of the
secondary code and the compilation state of the primary is still
ignored.
Move the compilation mode flag to the CompilationInfo.

Make class BitField able to use 32 bits of a uint32.
...
Although algorithmically correct, the compiler would not allow to instantiate
a BitField that uses all 32 bits without warnings about a too large shift
count. As a consequence we were limited to 31 bit values when using BitField.
This happened when instantiating a bitfield BitField<T, shift, size> with
[shift=0, size=32] or [shift=31, size=1] or more general any
[shift=X, size=32-X]
As side-effect of the new implementation the compiler now warns if we ever
try instantiating a bitfield with size 0.

Add a (currently) syntactic predicate to AST expression nodes telling
whether they are 'trivial'. Trivial expressions have no side effects,
do not require storage to be allocated for them, and can be evaluated
out of order (because their value does not change between when they
are visited by the code generator as expressions in the AST and when
it is consumed).
Mark 'this' and literals as trivial. Allow them to be pushed on the
virtual frame. Make use of them to push 'this' more lazily in this
property assignments.

Fix stack corruption when calling non-function.
...
Fix for issue 603.
Revision r3484 removed the property name from the call stack for
call ICs. When a non-function was called via a call IC and
Function.prototype.call, an extra value was left on the stack that the
caller could not know to clean up.
Fix is to change the JS builtin used for calling non-functions. It
now gets the callee as receiver, rather than iterating stack frames
and finding it on the expression stack of its JS caller.

Fix construction of simple objects with setters on prototype

Simple objects which are constructed without calling the actual constructor function did not take setters defined on prototype chain of the new object into account.
Constructing objects this way is now not done if there are setters involved on the prototype chain of the new object.
This only fixes the case where the setter is found when the first object from a constructor is created. If the prototype chain is changed new objects will on take any change to setters into account.

Don't externalize fresh strings.
...
With the current API the embedder has to extrenalize a string each
time a string is encountered to avoid the cost of repeated character
copying/conversion. The issue here is that the externalization cost
itself is non-negligible (both in time and space) and should not be
paid for a rarely used string. This change is an attempt to predict a
string's usage frequency based on its freshness. A string is
considered fresh if it was recently allocated in the new space.

Introduce number type information in the virtual frame.

Each frame element gets a new attribute with number type information. A frame element can be:
- smi
- heap number
- number (i.e. either of the above)
- or something else.
The type information is propagated along with all virtual frame operations.
Results popped from the frame carry the number information with them.
Two optimizations in the code generator make use of the new
information:
- GenericBinaryOpSyub omits map checks if input operands are numbers.
- Boolean conversion for numbers: Emit inline code for converting a number (smi or heap number) to boolean. Do not emit call to ToBoolean stub in this case.

If the result string is not found in the symbol table within a fixed number of probes a new string is just allocated.

Each variable use points to a variable definition structure

we can check whether its last use occurs later in the evaluation
order defined by the AST labeling number.
The new information is currently only printed out together with

Simple type tracking in the fast code generator.
...
Initial implementation of ad hoc must-be-smi tracking in the fast code
generator. Type information is used to avoid the write barrier for
smi property stores and to avoid the smi check for the inputs/output

Always load the JavaScript builtins code entry from the JavaScript

function instead of baking in the address of the first one that we see
in code.
This removes the need for fixups processing and makes the stubs safe
when there is no natives cache and therefore multiple versions of the
builtin functions.

Restrict the syntax that we aggressively optimize.

Do not use the speculative compiler for functions with other than one
statement in the body, and do not use it if subexpressions can have
side effects. Bailing out to the beginning of the full code is not
sound if side effects have already occurred.

Initial implementation of fast path operation for bitwise OR.
...
Support a binary operation (bitwise OR) so long as it's not nested in
the left subexpression. This ensures that the expression stack never
has height greater than two and so can be kept fully in registers.
The bounded expression stack height and the absence of any side
effects on the fast path allows us to still bailout out to the very
beginning of the function if any of our fast-path checks fail.

Fast compiler: Load globals variables directly from property cells.
...
This is a first step towards loading globals directly from property cells instead
of going through a load IC.
This change supports only properties with the DontDelete attribute since
we are only able to bailout into the generic code generated by the secondary
code generator the beginning of a function. The resulting fast-case code is
specialized for a specific context. When invoked with a different global object,
it will always bailout to the secondary code.
When loading a property that does not exist at compile-time or a property
that is deleteable we still generate the generic load IC.

Handle insertion order for simple constructors
...
When functions only have simple assignments of the form this.x = ... the object is created in generated code without actually calling the constructor. In this case the initial map for the function already contains the properties assigned in the constructor. The field descriptors in this initial map now has an enumeration index assigned to make property enumeration order the insertion order. The insertion order here is the order of the this.x assignments in the code.

RFC: Try to be much more careful with where we skip the write barrier by:

1. Avoid using SKIP_WRITE_BARRIER when we don't have to (smis).
2. Check and document the remaining uses of SKIP_WRITE_BARRIER.
3. Only allow GetWriteBarrierMode when in an AssertNoAllocation scope.
The only functional change should be in DeepCopyBoilerplate where we
no longer use the write barrier mode (because of allocations). I'm
running benchmarks to see if this has a measurable impact on performance.
