Change Math.random() to return 32 bits of random goodness, instead of 30 random bits. Math.random now allocates a HeapNumber inline, and calls a C funciton directly to put the random bits into it.

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.

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.

conditions so as to avoid inlining the floating-point code for them.

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.

Null, Boolean, String, or Number).

ToUInt32, ToUint16, ToString, or ToObject cannot invoke user code for
primitive input values. ToObject throws a TypeError if its input is

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.

Added zone-inl.h to jsregexp.h since it relies on calling new ZoneList which again relies on calling the static new method on Zone (defined in zone-inl.h but declared in zone.h).

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.

Remove unneeded variable usage analysis.
...
A variable usage analysis pass was run on toplevel and lazily-compiled
code but never used. Remove this pass and the data structures it
builds.
The representation of variable usage for Variables has been changed
from a struct containing a (weighted) count of reads and writes to a
simple flag. VariableProxies are always used, as before. The unused
"object uses" is removed.

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.

Fix stack tweaking in array allocation

When Array(0) or new Array(0) is handled by the generated code it is handled
by the same code as Array() and new Array(). For this to work the stack is
tweaked to remove the argument of value 0. However the argc was still passed
as 1 if a call to the runtime system was made.
When the stack is tweaked argc is also changed to 0.

[Linux] Patch LogSharedLibraryAddresses to work correctly on Android.

On 'usual' Linux systems in '/proc/self/maps' we encounter two entries
per library: one has 'rw-p' attrs and the other has 'r-xp'. While on
Android, I see 'rwxp' and 'r-xp' (both entries are marked executable.)
So I've added an explicit check for non-writability to leave only a
single record in the log file.

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.

Fix reliability crash caused by wrong assert.

These two asserts in ComputeEntryFrame are wrong since the
virtual frame already knows how to deal with the number type
information of copy elements: We do not store type
information with copy elements. Instead the backing element

Responsibility for binding labels is moved from the primary to the

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.

it is consumed).

Revision r3484 removed the property name from the call stack for

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.

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.

Pass the complete number type information into the GenericBinaryOpStub.
...
Currently we only pass a boolean parameter indicating whether
the input operands to the GenericBinaryOpStub are guaranteed
to be numbers or not.
Instead we pass the complete number type as a parameters. This
allows to use more precise type information for code generation
in the stub.
Also make the computation of the result type more precise and correct on both ia32 and x64.

Inline NumberToString

NumberToString in runtime JavaScript is inlined through a call to a stub. Currently the stub only checks the number string cache and only if the number is a smi. Code is shared with the inlining of number string cache lookup when adding a smi to a string.

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.

All two character string results from adding two strings and from sub string used to be handled in the runtime system as a lookup in the symbol table was done before allocating a new string. The native code for string add and sub string now probes the symbol cache for two character strings to avoid the runtime call. If the result string is not found in the symbol table within a fixed number of probes a new string is just allocated. Newly allocated two character strings are not added to the symbol table immediately.

Each variable use points to a variable definition structure

To determine whether a variable is live after a certain point
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

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.

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.

Refactoring and small optimization of the smi code for binary op stubs
...
on ia32.
1. Operate on the values in edx,eax when possible (all operations
except DIV and MOD). This saves moving them on entry and when falling
out to the non-smi code.
2. Do not perform ADD and SUB before the smi check of their inputs.
This saves undoing the operation in the case that we fall through to
the non-smi case due to non-smi inputs (probably common?), and we can
avoid emitting the smi check code twice (code size reduction).
3. Don't perform OR twice (once to smi check the inputs and once to
smi check the result).

Don't pass the "at start" parameter to native RegExp
...
As the start index is already passed it is easy to calculate the "at start" boolean in generated code. Also as direct entry has been implemented this needs to be done in generated code anyway, and therefore might as well be moved to the generated code for RegExp. The "at start" value is now calcualted as a local variable on the native RegExp frame based on the value of the start index argument.
The x64 version have been tested on both Linux and 64-bit Windows Vista.
For ARM I have tested cctest/test-regexp on ARM hardware, but the rest of the tests have only been run on the ARM simulator.

Use registers to pass arguments to GenericBinaryOpStub.
...
Currently arguments are never passed on registers (due to the way ArgsInRegistersSupported is written) and
if they were, the stub would break in several places because registers are not preserved properly in the
course of execution. This CL makes use of registers more often (than never) and makes sure that registers are
handler properly.
A peformance gain is small (0.2-0.3%) but stable.
This CL was extracted from the one sent out earlier (http://codereview.chromium.org/551093 ).

Fix issue 553: function frame is skipped in profile when compare stub is called.
...
The problem appeared due to a fact that stubs doesn't create a stack
frame, reusing the stack frame of the caller function. When building
stack traces, the current function is retrieved from PC, and its
callees are retrieved by traversing the stack backwards. Thus, for
stubs, the stub itself was discovered via PC, and then stub's caller's
caller was retrieved from stack.
To fix this problem, a pointer to JSFunction object is now captured
from the topmost stack frame, and is saved into stack trace log
record. Then a simple heuristics is applied whether a referred
function should be added to decoded stack, or not, to avoid reporting
the same function twice (from PC and from the pointer.)

Always invoke HeapObjectIterator::has_next() before invoking HeapObjectIterator::next().
This is necessary as ::has_next() has an important side-effect of going to the next
page when current page is exhausted.
And to find if pointers are encodable use more precise data---top of map space, not a number
of pages, as pages might stay in map space due to chunking.

Fix issue 571: display descriptive names for code objects from snapshot.
...
As this is only needed for internal profiling (not for DevTools),
the following approach had been chosen:
- during snapshot creation, positions of serialized objects inside
a snapshot are logged;
- then during V8 initialization, positions of deserealized objects
are logged;
- those positions are used for retrieving code objects names from
snapshot creation log, which needs to be supplied to tick processor
script.
Positions logging is controlled with the new flag: --log_snapshot_positions.
This flag is turned off by default, and this adds no startup penalty.
To plug this fix to Golem, the following actions are needed:
- logs created using 'mksnapshot' need to be stored along with VM images;
- tick processor script needs to be run with '--snapshot-log=...' cmdline
argument.

Small optimization of ARM compare stub. Reverse all references to
...
left and right sides of the comparison to reflect reality. Don't
check explicitly for NaNs when using VFP3 since the compare
operation can signal this case with the v flag. Use cmp instead
of tst in the fast compilers since tst leaves the v flag unchanged
and thus can only work by accident on non-equality comparisons.

Ensure correct boxing of values when calling functions on them
...
When a function is called with a value type as the receiver this is now boxed as an object.
This is a low-impact solution where the receiver is only boxed when required. For IC calls to the V8 builtins values are not boxed and as most of the functions on String.prototype, Number.prototype and Boolean.prototype are sitting there most IC calls on values will not need any boxing of the receiver.
For calls which are not IC calls but calls through the CallFunctionStub a flag is used to determine whether the receiver might be a value and only when that is the case will the receiver be boxed.
No changtes to Function.call and Function.apply - they already boxed values. According to the ES5 spec the receiver should not be boxed for these functions, but current browsers have not adopted that change yet.

Replace runtime call to NumberAdd with call to binary op stub.
Until now the top-level compiler always called a runtime function
for count operations.
In some places we expected in the JS builtins smis as arguments.
If we perform a count operation before all smis would get converted into
heap numbers by the runtime number add function and result in a runtime
assert.
Also: Add missing debugger information in the top-level compiler for
do-while loops.

Direct call to native RegExp code from JavaScript.
...
Calls to RegExp no longer have to be via a call to the runtime system. A new stub have been added which can handle this call in generated code. The stub checks all the parameters and creates RegExp entry frame in the same way as it is created by the runtime system. Bailout to the runtime system is done whenever an uncommon situation is encountered or when the static data used is not initialized. After running the native RegExp code the last match info is updated like in the runtime system.
Currently only ASCII strings are handled.
Added another argument to the RegExp entry frame. It indicated whether the call is direct from JavaScript code or through the runtime system. This information is used when RegExp execution is interrupted. If an interruption happens when RegExp code is called directly a retry is issued causing the interruption to be handled via the runtime system. The reason for this is that the direct call to RegExp code does not support garbage collection.

Simplify checking during allocation when Heap::always_allocate() is
...
true. The rules are:
1. Heap::AllocateRaw can normally handle allocation requests in new
space even when always_allocate() is true. It properly retries
failed allocation in the second 'retry' space.
2. Heap::Allocate can normally handle allocation requests in new
space.
3. We only need to check always_allocate() when explicitly requesting
allocation in new space via Heap::new_space().AllocateRaw().
4. The exception to these rules is fixed arrays with size such that
MaxObjectSizeInPagedSpace < size <= MaxObjectSizeInNewSpace (ie,
those that will be allocated in new space and promoted to large
object space). They cannot be allocated in new space via
Heap::Allocate or Heap::AllocateRaw, because the retry logic does
not know to allocate extra remembered set bits when retrying in
large object space.

to floating point and then converting back we convert directly to a
32 bit integer. In addition the bit twiddling implementation of float-
to-integer conversion has been ported from ARM. Testing has shown that
this runs faster than the x87 or SSE3 rounding instructions. This change
is IA32 only. There may be a smaller benefit from doing the same on x64.

Extend the maximum size map space
...
On 32-bit the maps are now aligned on a 32-byte boundary in order to encode more maps during compacting GC. The actual size of a map on 32-bit is 28 bytes making this change waste 4 bytes per map.
On 64-bit the encoding for compacting GC is now using more than 32-bits and the maps here are still pointer size aligned. The actual size of a map on 64-bit is 48 bytes and this change does not intruduce any waste.
My choice of 16 bits for kMapPageIndexBits for 64-bit should give the same maximum number of pages (8K) for map space. As maps on 64-bit are larger than on 32-bit the total number of maps on 64-bit will be smaller than on 32-bit. We could consider raising this to 17 or 18.
I moved the kPageSizeBits to globals.h as the calculation of the encoding really depended on this.
There are still an #ifdef/#endif in objects.h and this constant could be moved to globaks.h as well, but I kept it together with the related constants.
All the tests run in debug mode with additional options --gc-global --always-compact as well (except for a few tests on which also fails before this change when run with --gc-global --always-compact).

Fix a crash caused by garbage collection during generation of a
...
callback load (or keyed load) IC.
The problem was that the IC code calls a stub, which can allocate and
thus trigger a GC if the stub is not already generated. Problem is
solved by adding the ability to "try" to call a stub, trying to
generate the stub code if necessary but signaling an allocation
failure if generating the code is not possible.

External string table.
...
Instead of weak handles external strings use a separate table. This
table uses 5 times less memory than weak handles. Moreover, since we
don't have to follow the weak handle callback protocol we can collect
the strings faster and even on scavenge collections.

This adds a code stub which can do most of what Heap::AllocateConsString can do. It bails out if the result cannot fit in new space or if the result is a short (flat) string and one argument is an ascii string and the other a two byte string. It also bails out if adding two one character strings as Heap::AllocateConsString has special handling of this utilizing the symbol table. The stub is used both for the binary add operation and for StringAdd calls from runtime JavaScript files. Extended the string add test to cover all sizes of flat result stings.

Remove the last context dependent reference from the Script object
...
For scripts originating from a call to eval the Script object used to hold a reference to the function from where the eval was called together with the code offset within that function of the eval call. This is used by the stack trace and is part of the debugger protocol. In order to avoid storing the function the script, the position within the script and the name of the function calling eval is stored instead. This avoids holding context dependent objects in the script object.
The calculation of the position of the eval in the script holding the eval is now done when the eval script is compiled as it is not possible to postpone this unless a reference is kept to the generated code for the function calling eval.

Fix bug in the fast compiler's object literal code
...
Fixes issue 526:
BUG=http://code.google.com/p/v8/issues/detail?id=526
The object literals code in the fast compiler returned an incorrect result
when getter or setters are defined together with computed properties.
Added a regression test that captures the most reduced version of this
problem.
Also added a test for object literals with getters/setters and
prototype properties.

Remove the different length string types
...
The different length string types was used to encode the string length and the hash in one field. This is now split into two fields one for length and one for hash. The hash field still encodes the array index of the string if it has one. If an array index is encoded in the hash field the string length is added to the top bits of the hash field to avoid a hash value of zero.
On 32-bit this causes an additional 4 bytes to be used for all string objects. On 64-bit this will be half on average dur to pointer alignment.

Implement IS_OBJECT and IS_FUNCTION as inlined runtime functions.
...
Summary:
This change fixes a performance regression introduced by the special
handling of regular expressions in typeof expressions.
As a result we regain ~8% speedup on 3d-raytrace and ~13% on boyer
(vs bleeding edge)
Description:
The macros IS_OBJECT and IS_FUNCTION are frequently used in the
JS runtime functions.
By introducing new inlined runtime functions %_IsFunction and %_IsObject
we avoid invoking the more expensive %_ClassOf function plus comparing
its result to a string.

Re-enable using push instructions for syncing the virtual frame.
...
This change fixes the problem with the original version of this approach
(r3032) that may lead to a corrupted stack if we would invoke spilling during
syncing a large SMI constant (unsafe SMIs) in the virtual frame.
The new code for storing unsafe SMI constants does not use an extra temporary
register. This prevents the compiler from ever having to spill during a
virutal frame sync operation.
For storing a large SMI constant we previously generated:
mov ecx, (large_smi & 0x0000ffff)
xor ecx, (large_smi & 0xffff0000)
push ecx
we now generate:
push (large_smi & 0x0000ffff)
or [esp], (large_smi & 0xffff0000)
Not using a temporary register avoids spilling within an nvocation
of VirtualFrame::SyncRange.

Top-level compiler: Re-allow non-lazily compiled function literals.
...
This change re-allows non-lazy compiled function literals for top-level compilation.
There was a problem on ARM exposed through this change which was fixed as part of r3289
in fast-codegen-arm.cc (Threading and Threading2 tests failed)
It occurred before r3289 when we allocate a local context at the beginning of a function. The
code for the stack check was split up in an unintended way (load of stack check limit into r2,
and use of r2 in the actual stack check code).

regular expressions to be consistent with typeof in other contexts.
Typeof regular expressions should now be 'function' in all contexts.

Fix issue 493: Infinite loop when debug break is set when entering function.apply.
...
In the generated code for function.apply there was a loop checking the stack limit for interruption. This loop would call into the runtime system to handle interuption and keep running until there was no interruption. However if the interuption was debug break the runtime system would never clear the interruption as debug break is prevented in builtins are prevented and the assumption here was that returning with the debug break flag set would move execution forward.
Renamed initial_jslimit and initial_climit to real_jslimit and real_climit. Renamed a few external references related to the stack limit as well.
Exposed the real stack limit to generated code to make the stack check when entering function.apply use the real stack limit and not the stack limit which is changed to signal interruption.
Added the real stack limit to the roots array.

Rework the way we handle the fact that the ARM simulator uses a
...
separate JS stack.
In exception handling, we need to be able to compare addresses into
the JavaScript portion of the stack with the address of a C++ handler
on the stack. Since the stacks are separate on the simulator, we need
a JavaScript stack address corresponding to a C++ try catch handler in
order to perform valid address comparisons.
On the simulator, we now link the C++ try catch handlers indirectly
through the JS stack and use the JS stack indirection address for
comparisons.
JS C++
handler
[C++ address] <------ next_
\
\
\----> handler
[C++ address] <------ next_
On actual hardware the C++ try catch handlers continue to be directly
linked.

typeof(true ? x : y) // throws ReferenceError

Initial implementation of top-level compilation of expressions in test
...
context. Test contexts are used for the left subexpressions of
short-circuited boolean operators. The right subexpressions inherit
their expression context from the binary op expression.
Compilation of short-circuited operations in effect and test context
is straightforward:
effect(e0 || e1) =
test(e0, L0, L1)
L1: effect(e1)
L0:
test(e0 || e1, L0, L1) =
test(e0, L0, L2)
L2: test(e1, L0, L1)
Because the value of the first subexpression may be needed as the
value of the whole expression in a value context, we introduce a
hybrid value/test contest (the value is needed if true, but not if
false).
value(e0 || e1) =
value/test(e0, L0, L1)
L1: value(e1)
L0:
The compilation of value/test and test/value (introduced by boolean
AND) is:
value/test(e0 || e1, L0, L1) =
value/test(e0, L0, L2)
L2: value/test(e1, L0, L1)
test/value(e0 || e1, L0, L1) =
test(e0, L0, L2)
L2: test/value(e1, L0, L1)
Boolean AND is the dual. The AST nodes themselves (not their parents)
are responsible for producing the proper result (effect, value, or
control flow) depending on their context.

Support for property assignment in the fast compiler.
...
The code for .result = (b.y = 99) where b is a global variable is:
push [esi+0x17]
mov ecx,0xf5c229ad ;; object: 0xf5c229ad <String[1]: b>
call LoadIC_Initialize
nop
mov [esp],eax
mov eax,0xc6
mov ecx,0xf5c25c41 ;; object: 0xf5c25c41 <String[1]: y>
call StoreIC_Initialize
nop
mov [esp],eax
pop [ebp+0xf4]
There is still some room for improvement in the generated code.
Other changes:
- Replaced switch-statement in FastCodeGenerator::VisitProperty with DropAndMove(...)
- Do not emit nop after IC calls on ARM.

Rename the kinds of locations to be consistent with the (codegen)
...
context of the expressions they label. Introduce an "unintialized"
location to catch failure to assign any location at all.
Changed the object literal initialization on ARM to use a Store IC in
the same cases where it did on the other platforms. This was required
because the location of the literal property name is given an
"unitialized" location.

In the toplevel compiler, shift the responsibility of assigning a
...
location to an Expression AST node from the node's parent to the node
itself.
This allows an inherited code generation context from a parent node to
be passed arbitrarily far down the tree (eg, the subexpression of a
unary not is in the same context as the unary expression itself, the
then and else subexpressions of the ternary operator are in the same
context as the whole expression, and so forth).
We do not yet take advantage of this in the backend (eg, the right
subexpression of short-circuited OR is still compiled by using the
parent's destination location, rather than the subexpression's
itself).

- don't engage the processing thread of CPU profiling until the first time profiling is resumed, this saves us a thread allocation for the majority of users;
