Remove usage of JSArray in Script object
...
Storing a JSArray in the Script object could cause an indirect reference from the compilation cache to a global object to be created. Now the line ends are only stored as a FixedArrya and when that is needed in JavaScript a JSArray copy is created. Changed some of the JavaScript code to cache the line ends in a local variable for better performance.

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.

Based on review feedback, defined the behavior of storing NaN and

test cases. Added fucomi instruction to assembler. Fixed bug in
KeyedLoadIC::GenerateExternalArray when allocation of HeapNumber
failed. Fixed bug in encoding of 16-bit immediate arithmetic
instructions in 64-bit port.
Removed raising of exceptions for negative array indices passed to
external arrays and associated tests. Based on current discussion in

throwing altogether.

Added infrastructure for optimizing new CanvasArray types in WebGL
...
specification under development. The optimizations are patterned after
those previously done for CanvasPixelArray. This CL adds all of the
necessary framework but continues to use the generic KeyedLoadIC and
KeyedStoreIC code, to create a baseline for benchmarking purposes. The
next CL will add the optimized ICs to ic-ia32.cc and ic-x64.cc.
These new CanvasArray types have different semantics than
CanvasPixelArray; out-of-range values are clamped via C cast
semantics, which is cheaper than the clamping behavior specified by
CanvasPixelArray. Out-of-range indices raise exceptions instead of
being silently ignored.
As part of this work, pulled FloatingPointHelper::AllocateHeapNumber
up to MacroAssembler on ia32 and x64 platforms. Slightly refactored
KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and
added a few more instructions that are needed for the new ICs. The
test cases in test-api.cc have been verified by hand to exercise all
of the generated code paths in the forthcoming specialized ICs.

Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.

A simple fix of issue http://code.google.com/p/chromium/issues/detail?id=3285
...
NPN_Construct allows a NPObject to be called as a construct. For example, the
test case
var s = new app.Packages.java.lang.Integer(5);
app.Packages.java.lang.Integer is a NPObject, and it implements NPN_Construct.
This fix allows a JSObject created by an API function be called as a construct
if it can be called
as a function. This is done by generating the same code for
var s = new app.Packages.java.lang.Integer(5); as
var s = app.Packages.java.lang.Integer(5);
and the caller handles both case correctly. A more sophiscated fix is to one
extra JSConstructCall
frame and allow CallAsConstructor in Builtin::HandleApiCallAsFunction.
This change itself shouldn't affect the semantic of normal case such as:
var a = {};
var s = new a();
A TypeError exception will be thrown in CALL_NON_FUNCTION (runtime.js).
Another part of fix is in the binding code, V8NPObject, which makes
NPN_InvokeDefault or NPN_Construct
call depending on which function is available.

Change the enumeration order for unsigned integer keys to always be
...
numerical order independently of the representation of the object.
Exchanged the order of enumeration of integer and string keys so
integer keys are first instead of string keys to better match
WebKit/JSC behavior.
Added test cases that document our enumeration order choice.

Reland exception propagation fix.
...
Fix exception propagation problem where undefined was returned instead
of an empty handle in case of an exception. This problem can break
C++ programs that are not interested in catching exceptions and just
want to propagate them out by testing for empty handles.
The issue is that exceptions are not rescheduled if they are
externally caught. Externally caught exceptions have to be
rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.
A couple of tests will fail on the ARM simulator because the simulator
has separate stacks for C++ and JavaScript. I have marked the tests
as failing only on the simulator.

Fixed a bunch of memory leaks in tests, including:
...
- String traversal test data (now in a zone)
- Debug message thread (now joined on exit)
- Threading test threads (now joined on exit)
- Changed message tests framework to cope with valgrind
Also, fixed a bug where we'd try to delete stack-allocated objects
when tearing down v8. Good times.

Fix bug in context stores, where the store was ignored if there was a
...
read-only property in the prototype chain. Stores should only be
ignored if there is a read-only property on the object itself.
