-        Rename PatchBuffer to LinkBuffer.  Previously our terminology has been a little
-        mixed up, but we have decided to fix on refering to the process that takes place
-        at the end of code generation as 'linking', and on any modifications that take
-        place later (and once the code has potentially already been executed) as 'patching'.
-
-        However, the term 'PatchBuffer' is already in use, and needs to be repurposed.
-
-        To try to minimize confusion, we're going to switch the terminology over in stages,
-        so for now we'll refer to later modifications as 'repatching'.  This means that the
-        new 'PatchBuffer' has been introduced with the name 'RepatchBuffer' instead.
-
-        This patch renames the old 'PatchBuffer' to 'LinkBuffer'.  We'll leave ToT in this
-        state for a week or so to try to avoid to much overlap of the meaning of the term
-        'PatchBuffer', then will come back and rename 'RepatchBuffer'.

-        Having moved most of their functionality into the RepatchBuffer class,
-        we can simplify the CodeLocation* classes.
-
-        The CodeLocation* classes are currently a tangle of templatey and friendly
-        badness, burried in the middle of AbstractMacroAssembler.  Having moved
-        the ability to repatch out into RepatchBufer they are now do-nothing wrappers
-        on CodePtr (MacroAssemblerCodePtr), that only exist to provide type-safety.
-
-        Simplify the code, and move them off into their own header.

-        Having introduced the RepatchBuffer, ProcessorReturnAddress is now a do-nothing
-        wrapper around ReturnAddressPtr.  Remove it.  In tugging on this piece of string
-        it made sense to roll out the use of ReturnAddressPtr a little further into

-        Move repatching methods into a set of methods on a class.  This will allow us to
-        coallesce memory reprotection calls.  Really, we want this class to be called
-        PatchBuffer, we want the class PatchBuffer to be called LinkBuffer, we want both
-        to be memblers of MacroAssembler rather then AbstractMacroAssembler, we don't
-        want the CodeLocationFoo types anymore (they are now only really there to provide
-        type safety, and that is completely undermined by the way we use offsets).  Then
-        the link & patch buffers should delegate the actual patching calls to the
-        architecture-specific layer of the MacroAssembler.  Landing all these changes as a
-        sequence of patches.

-        We are currently generating two copies of the slow path for op_call for no reason.  Stop that.
-
-        Originally op_call used two slow paths since the first set up the pointer to the CallLinkInfo
-        for use when linking.  However this is now looked up using the return address (as we do for
-        property accesses) so the two paths are now identical.

-        more semantic information.  The new types are:
-        
-            * MacroAssemblerCodePtr - this wraps a pointer into JIT generated code.
-            * FunctionPtr - this wraps a pointer to a C/C++ function in JSC.
-            * ReturnAddressPtr - this wraps a return address resulting from a 'call' instruction.
-
-        Wrapping these types allows for stronger type-checking than is possible with everything
-        represented a void*.  For example, it is now enforced by the type system that near
-        calls can only be linked to JIT code and not to C functions in JSC (this was previously
-        required, but could not be enforced on the interface).

-        Change JITStub functions from being static members on the JITStub class to be
-        global extern "C" functions, and switch their the function signature declaration
-        in the definition of the functions to be C-macro generated.  This makes it easier
-        to work with the stub functions from assembler code (since the names no longer
-        require mangling), and by delaring the functions with a macro we can look at
-        also auto-generating asm thunks to wrap the JITStub functions to perform the
-        work currently in 'restoreArgumentReference' (as a memory saving).
-
-        Making this change also forces us to be a bit more realistic about what is private
-        on the Register and CallFrame objects.  Presently most everything on these classes
-        is private, and the classes have plenty of friends.  We could befriend all the
-        global functions to perpetuate the delusion of encapsulation, but using friends is
-        a bit of a sledgehammer solution here - since friends can poke around with all of
-        the class's privates, and since all the major classes taht operate on Regsiters are
-        currently friends, right there is currently in practice very little protection at
-        all.  Better to start removing friend delclarations, and exposing just the parts
-        that need to be exposed.

-        Allow the JIT to operate without relying on use of RWX memory, on platforms where this is supported.
-
-        This patch adds a switch to Platform.h (ENABLE_ASSEMBLER_WX_EXCLUSIVE) which enables this mode of operation.
-        When this flag is set, all executable memory will be allocated RX, and switched to RW only whilst being
-        modified.  Upon completion of code generation the protection is switched back to RX to allow execution.
-
-        Further optimization will be required before it is desirable to enable this mode of operation by default;

-        Allow the buffer underlying UString to be shared.
-
-        In order to not grow the underlying size of any structure,

-         + m_sharedBuffer -- a pointer to the shared ref counted buffer
-           if the class is BaseString and the buffer is being shared OR

-        op_method_check
-
-        Optimize method calls, by caching specific function values within the Structure.
-        The new opcode is used almost like an x86 opcode prefix byte to optimize op_get_by_id,
-        where the property access is being used to read a function to be passed to op-call (i.e.
-        'foo.bar();').  This patch modifies the Structure class such that when a property is
-        put to an object for the first time we will check if the value is a function.  If it is,
-        we will cache the function value on the Structure.  A Structure in such a state guarantees
-        that not only does a property with the given identifier exist on the object, but also that
-        its value is unchanged.  Upon any further attempt to put a property with the same identifier
-        (but a different value) to the object, it will transition back to a normal Structure (where
-        it will guarantee the presence but not the value of the property).
-
-        op_method_check makes use of the new information made available by the Structure, by
-        augmenting the functionality of op_get_by_id.  Upon generating a FunctionCallDotNode a
-        check will be emitted prior to the property access reading the function value, and the JIT
-        will generate an extra (initially unlinked but patchable) set of checks prior to the regular
-        JIT code for get_by_id.  The new code will do inline structure and prototype structure check
-        (unlike a regular get_by_id, which can only handle 'self' accesses inline), and then performs
-        an immediate load of the function value, rather than using memory accesses to load the value
-        from the obejct's property storage array.  If the method check fails it will revert, or if
-        the access is polymorphic, the op_get_by_id will continue to operate - and optimize itself -
-        just as any other regular op_get_by_id would.
-
-        ~2.5% on v8-tests, due to a ~9% progression on richards.

-        Addition of MacroAssemblerCodeRef.h rubber stamped by Geoff Garen.
-
-        Refactor JIT code-handle objects.  The representation of generated code is currently
-        a bit of a mess.  We have a class JITCode which wraps the pointer to a block of
-        generated code, but this object does not reference the executable pool meaning that
-        external events (the pool being derefed) could make the pointer become invalid.
-        To overcome this both the JIT and Yarr implement further (and similar) objects to
-        wrap the code pointer with a RefPtr to the pool.  To add to the mire, as well as the
-        CodeBlock containing a handle onto the code the FunctionBodyNode also contains a
-        copy of the code pointer which is used almost (but not entirely) uniquely to access
-        the JIT code for a function.
-
-        Rationalization of all this:
-
-            * Add a new type 'MacroAssembler::CodeRef' as a handle for a block of JIT generated code.
-            * Change the JIT & Yarr to internally handle code using CodeRefs.
-            * Move the CodeRef (formerly anow defunct JITCodeRef) from CodeBlock to its owner node.
-            * Remove the (now) redundant code pointer from FunctionBodyNode.
-
-        While tidying this up I've made the PatchBuffer return code in new allocations using a CodeRef,
-        and have enforced an interface that the PatchBuffer will always be used, and 'finalizeCode()' or
-        'finalizeCodeAddendum()' will always be called exactly once on the PatchBuffer to complete code generation.
-
-        This gives us a potentially useful hook ('PatchBuffer::performFinalization()') at the end of generation,
-        which may have a number of uses.  It may be helpful should we wish to switch our generation
-        model to allow RW/RX exclusive memory, and it may be useful on non-cache-coherent platforms to
-        give us an oportunity to cache flush as necessary.
-
-        No performance impact.

-        on side effects in the Lexer. Move the creation of numeric identifiers
-        out of this file and into the PropertyNode constructor.
-
-        * parser/Lexer.cpp:
-        (JSC::Lexer::setCode): Pass in ParserArena, used for identifiers.
-        (JSC::Lexer::makeIdentifier): Changed return type to const Identifier*
-        and changed to call ParserArena.
-        (JSC::Lexer::scanRegExp): Added out arguments that are const Identifier*
-        as well as a prefix character argument so we can handle the /= case
-        without a string append.
-        (JSC::Lexer::skipRegExp): Added. Skips a regular expression without
-        allocating Identifier objects.
-        (JSC::Lexer::clear): Removed the code to manage m_identifiers, m_pattern,
-        and m_flags, and added code to set m_arena to 0.

-
-        * parser/NodeConstructors.h:
-        (JSC::ParserArenaFreeable::operator new): Added. Calls allocateFreeable
-        on the arena.
-        (JSC::ParserArenaDeletable::operator new): Changed to call the
-        allocateDeletable function on the arena instead of deleteWithArena.
-        (JSC::RegExpNode::RegExpNode): Changed arguments to Identifier instead
-        of UString since these come from the parser which makes identifiers.
-        (JSC::PropertyNode::PropertyNode): Added new constructor that makes
-        numeric identifiers. Some day we might want to optimize this for
-        integers so it doesn't create a string for each one.
-        (JSC::ContinueNode::ContinueNode): Initialize m_ident to nullIdentifier
-        since it's now a const Identifier& so it can't be left uninitialized.
-        (JSC::BreakNode::BreakNode): Ditto.
-        (JSC::CaseClauseNode::CaseClauseNode): Updated to use SourceElements*
-        to keep track of the statements rather than a separate statement vector.
-        (JSC::BlockNode::BlockNode): Ditto.
-        (JSC::ForInNode::ForInNode): Initialize m_ident to nullIdentifier.

-        (JSC::SourceElements::singleStatement): Added.
-        (JSC::SourceElements::lastStatement): Added.
-        (JSC::RegExpNode::emitBytecode): Updated since the pattern and flags

-        to use the substitution mechanism instead of doing a string append.
-        (JSC::SourceElements::emitBytecode): Added. Replaces the old
-        statementListEmitCode function, since we now keep the SourceElements
-        objects around.
-        (JSC::BlockNode::lastStatement): Added.
-        (JSC::BlockNode::emitBytecode): Changed to use emitBytecode instead of

-        (JSC::ScopeNode::emitStatementsBytecode): Added.
-        (JSC::ScopeNode::singleStatement): Added.
-        (JSC::ProgramNode::emitBytecode): Call emitStatementsBytecode instead
-        of statementListEmitCode.
-        (JSC::EvalNode::emitBytecode): Ditto.
-        (JSC::EvalNode::generateBytecode): Removed code to clear the children
-        vector. This optimization is no longer possible since everything is in
-        a single arena.
-        (JSC::FunctionBodyNode::emitBytecode): Call emitStatementsBytecode
-        insetad of statementListEmitCode and check for the return node using
-        the new functions.
-
-        * parser/Nodes.h: Changed VarStack to store const Identifier* instead
-        of Identifier and rely on the arena to control lifetime. Added a new
-        ParserArenaFreeable class. Made ParserArenaDeletable inherit from
-        FastAllocBase instead of having its own operator new. Base the Node
-        class on ParserArenaFreeable. Changed the various Node classes
-        to use const Identifier& instead of Identifier to avoid the need to
-        call their destructors and allow them to function as "freeable" in the
-        arena. Removed extraneous JSC_FAST_CALL on definitions of inline functions.
-        Changed ElementNode, PropertyNode, ArgumentsNode, ParameterNode,
-        CaseClauseNode, ClauseListNode, and CaseBlockNode to use ParserArenaFreeable
-        as a base class since they do not descend from Node. Eliminated the
-        StatementVector type and instead have various classes use SourceElements*
-        instead of StatementVector. This prevents those classes from having th
-        use ParserArenaDeletable to make sure the vector destructor is called.
-
-        * parser/Parser.cpp:
-        (JSC::Parser::parse): Pass the arena to the lexer.
-
-        * parser/Parser.h: Added an include of ParserArena.h, which is no longer
-        included by Nodes.h.
-
-        * parser/ParserArena.cpp:
-        (JSC::ParserArena::ParserArena): Added. Initializes the new members,
-        m_freeableMemory, m_freeablePoolEnd, and m_identifiers.
-        (JSC::ParserArena::freeablePool): Added. Computes the pool pointer,
-        since we store only the current pointer and the end of pool pointer.
-        (JSC::ParserArena::deallocateObjects): Added. Contains the common
-        memory-deallocation logic used by both the destructor and the
-        reset function.
-        (JSC::ParserArena::~ParserArena): Changed to call deallocateObjects.
-        (JSC::ParserArena::reset): Ditto. Also added code to zero out the
-        new structures, and switched to use clear() instead of shrink(0) since
-        we don't really reuse arenas.
-        (JSC::ParserArena::makeNumericIdentifier): Added.
-        (JSC::ParserArena::allocateFreeablePool): Added. Used when the pool
-        is empty.
-        (JSC::ParserArena::isEmpty): Added. No longer inline, which is fine
-        since this is used only for assertions at the moment.
-
-        * parser/ParserArena.h: Added an actual arena of "freeable" objects,
-        ones that don't need destructors to be called. Also added the segmented
-        vector of identifiers that used to be in the Lexer.
-
-        * runtime/FunctionConstructor.cpp:
-        (JSC::extractFunctionBody): Use singleStatement function rather than
-        getting at a StatementVector.
-
-        * runtime/FunctionPrototype.cpp:
-        (JSC::functionProtoFuncToString): Call isHostFunction on the body
-        rather than the function object.
-
-        * runtime/JSFunction.cpp:
-        (JSC::JSFunction::JSFunction): Moved the structure version of this in
-        here from the header. It's not hot enough that it needs to be inlined.
-        (JSC::JSFunction::isHostFunction): Moved this in here from the header.
-        It's now a helper to be used only within the class.
-        (JSC::JSFunction::setBody): Moved this in here. It's not hot enough that
-        it needs to be inlined, and we want to be able to compile the header
-        without the definition of FunctionBodyNode.
-
-        * runtime/JSFunction.h: Eliminated the include of "Nodes.h". This was
-        exposing too much JavaScriptCore dependency to WebCore. Because of this
-        change and some changes made to WebCore, we could now export a lot fewer
-        headers from JavaScriptCore, but I have not done that yet in this check-in.
-        Made a couple functions non-inline. Removes some isHostFunction() assertions.
-        
-        * wtf/FastAllocBase.h: Added the conventional using statements we use in
-        WTF so we can use identifiers from the WTF namespace without explicit
-        namespace qualification or namespace directive. This is the usual WTF style,
-        although it's unconventional in the C++ world. We use the namespace primarily
-        for link-time disambiguation, not compile-time.

-        Add SamplingCounter tool to provide a simple mechanism for counting events in JSC
-        (enabled using ENABLE(SAMPLING_COUNTERS)).  To count events within a single function
-        use the class 'SamplingCounter', where the counter may be incremented from multiple
-        functions 'GlobalSamplingCounter' may be convenient; all other counters (stack or
-        heap allocated, rather than statically declared) should use the DeletableSamplingCounter.
-        Further description of these classes is provided alongside their definition in

-
-        Counters may be incremented from c++ by calling the 'count()' method on the counter,
-        or may be incremented by JIT code by using the 'emitCount()' method within the JIT.

-        ThreadIdentifier is now a class, containing a PlatformThreadIdentifier and
-        methods that are used across the code on thread ids: construction, comparisons,
-        check for 'valid' state etc. '0' is used as invalid id, which happens to just work
-        with all platform-specific thread id implementations.
-
-        All the following files repeatedly reflect the new ThreadIdentifier for each platform.
-        We remove ThreadMap and threadMapMutex from all of them, remove the functions that
-        populated/searched/cleared the map and add platform-specific comparison operators
-        for ThreadIdentifier.
-
-        There are specific temporary workarounds for Safari 4 beta on OSX and Win32 since the
-        public build uses WTF threading functions with old type of ThreadingIdentifier.
-        The next time Safari 4 is rebuilt, it will 'automatically' pick up the new type and new
-        functions so the deprecated ones can be removed.

-        (WTF::waitForThreadCompletion): This is a workaround for Safari 4 beta on Mac.
-        Safari 4 is linked against old definition of ThreadIdentifier so it treats it as uint32_t.
-        This 'old' variant of waitForThreadCompletion takes uint32_t and has the old decorated name, so Safari can
-        load it from JavaScriptCore library. The other functions (CurrentThread() etc) happen to match their previous
-        decorated names and, while they return pthread_t now, it is a pointer which round-trips through a uint32_t.

-        by thread id, createThread now closes the handle.
-        (WTF::waitForThreadCompletion): obtains another one using OpenThread(id) API. If can not obtain a handle,
-        it means the thread already exited.

-        Fix (kinda) for sampling tool breakage.  The codeblock sampling tool has become
-        b0rked due to recent changes in native function calling.  The initialization of
-        a ScopeNode appears to now occur before the sampling tool (or possibly the
-        interpreter has been brought into existence, wihich leads to crashyness).
-
-        This patch doesn't fix the problem.  The crash occurs when tracking a Scope, but
-        we shouldn't need to track scopes when we're just sampling opcodes, not
-        codeblocks.  Not retaining Scopes when just opcode sampling will reduce sampling
-        overhead reducing any instrumentation skew, which is a good thing.  As a side
-        benefit this patch also gets the opcode sampling going again, albeit in a bit of
-        a lame way.  Will come back later with a proper fix from codeblock sampling.

-        Previously, when appending to an existing string and growing the underlying buffer,
-        we would actually allocate 110% of the required size in order to give us some space
-        to expand into.  Now we treat strings differently based on their size:
-
-        Small Strings (up to 4 pages):
-        Expand the allocation size to 112.5% of the amount requested.  This is largely sicking
-        to our previous policy, however 112.5% is cheaper to calculate.
-
-        Medium Strings (up to 128 pages):
-        For pages covering multiple pages over-allocation is less of a concern - any unused
-        space will not be paged in if it is not used, so this is purely a VM overhead.  For
-        these strings allocate 2x the requested size.
-
-        Large Strings (to infinity and beyond!):
-        Revert to our 112.5% policy - probably best to limit the amount of unused VM we allow
-        any individual string be responsible for.
-
-        Additionally, round small allocations up to a multiple of 16 bytes, and medium and
-        large allocations up to a multiple of page size.
-
-        ~1.5% progression on Sunspider, due to 5% improvement on tagcloud & 15% on validate.

-        Fix crash due to incorrectly using an invalid scopechain 
-
-        stringProtoFuncReplace was checking for an exception on a CachedCall
-        by asking for the cached callframes exception.  Unfortunately this
-        could crash in certain circumstances as CachedCall does not guarantee
-        a valid callframe following a call.  Even more unfortunately the check
-        was entirely unnecessary as there is only a single exception slot per
-        global data, so it was already checked via the initial exec->hadException()
-        check.
-
-        To make bugs like this more obvious, i've added a debug only destructor
-        to ScopeChainNode that 0's all of its fields.  This exposed a crash in
-        the standard javascriptcore tests.

-        Enable op_strcat across += assignments.  This patch allows the lhs of a read/modify node
-        to be included within the concatenation operation, and also modifies the implementation
-        of the concatenation to attempt to reuse and cat onto the leftmost string, rather than
-        always allocating a new empty output string to copy into (as was previously the behaviour).

-        Bug 25559: Improve native function call performance
-        <https://bugs.webkit.org/show_bug.cgi?id=25559>
-
-        In order to cache calls to native functions we now make the standard
-        prototype functions use a small assembly thunk that converts the JS
-        calling convention into the native calling convention.  As this is
-        only beneficial in the JIT we use the NativeFunctionWrapper typedef
-        to alternate between PrototypeFunction and JSFunction to keep the
-        code sane.  This change from PrototypeFunction to NativeFunctionWrapper
-        is the bulk of this patch.

-        Split out the two cases for InIdentifierOrKeyword and InIdentifier.
-        Added special case tight loops for identifiers and other simple states.
-        Removed a branch from the code that sets m_atLineStart to false using goto.
-        Streamlined the number-handling code so we don't check for the same types

-        (JSC::Lexer::scanRegExp): Tweaked style a bit.
-        (JSC::Lexer::clear): Clear m_codeWithoutBOMs so we don't use memory after

-        (JSC::Lexer::sourceCode): Made this no-longer inline since it has more

-        which is the same as isASCIIOctalDigit. Eliminated unused arguments from
-        matchPunctuator. Added copyCoodeWithoutBOMs and currentOffset. Moved the
-        makeIdentifier function out of the header. Added lastTokenWasRestrKeyword
-        function. Added new constants for m_skipLineEnd. Removed unused yycolumn,

-        * parser/Lexer.cpp:
-        (JSC::Lexer::setCode): Moved below shift() so it can inline.
-        (JSC::Lexer::scanRegExp):  Use resize(0) instead of clear() on Vectors, since the intent
-        here is not to free the underlying buffer.
-        (JSC::Lexer::lex): ditto; also, change the loop logic a bit for the main lexing loop
-        to avoid branching on !m_done twice per iteration. Now we only check it once.
-        (JSC::Lexer::shift): Make this ALWAYS_INLINE and tag an unusual branch as UNLIKELY
-        * parser/Lexer.h:
-        (JSC::Lexer::makeIdentifier): force to be ALWAYS_INLINE
-        * wtf/Vector.h:
-        (WTF::::append): force to be ALWAYS_INLINE (may have helped in ways other than parsing but it wasn't
-        getting inlined in a hot code path in the lexer)

-        Add mechanism to vend heap allocated JS numbers to JavaScriptCore API clients with a
-        representation that is independent of the number representation in the VM.
-        - Numbers leaving the interpreter are converted to a tagged JSNumberCell.
-        - The numbers coming into the interpreter (asserted to be the tagged JSNumberCell) are
-          converted back to the VM's internal number representation.

-        Add SamplingFlags mechanism.
-
-        This mechanism allows fine-grained JSC and JavaScript program aware
-        performance measurement.  The mechanism provides a set of 32 flags,
-        numbered #1..#32.  Flag #16 is initially set, and all other flags
-        are cleared.  Flags may be set and cleared from within
-
-        Enable by setting ENABLE_SAMPLING_FLAGS to 1 in wtf/Platform.h.
-        Disabled by default, no performance impact.  Flags may be modified
-        by calling SamplingFlags::setFlag() and SamplingFlags::clearFlag()
-        from within JSC implementation, or by calling setSamplingFlag() and
-        clearSamplingFlag() from JavaScript.
-
-        The flags are sampled with a frequency of 10000Hz, and the highest
-        set flag in recorded, allowing multiple events to be measured (with
-        the highest flag number representing the highest priority).

-        Coallesce input checking and reduce futzing with the index position
-        between alternatives and iterations of the main loop of a regex,
-        when run in YARR.
-
-        Consider the following regex:  /foo|bar/
-        
-        Prior to this patch, this will be implemented something like this pseudo-code description:
-        
-        loop:
-            check_for_available_input(3) // this increments the index by 3, for the first alterantive.
-                if (available) { test "foo" }
-            decrement_index(3)
-            check_for_available_input(3) // this increments the index by 3, for the second alterantive.
-                if (available) { test "bar" }
-            decrement_index(3)
-            check_for_available_input(1) // can we loop again?
-                if (available) { goto loop }
-
-        With these changes it will look more like this:
-
-            check_for_available_input(3) // this increments the index by 3, for the first alterantive.
-            if (!available) { goto fail }
-        loop:
-            test "foo"
-            test "bar"
-            check_for_available_input(1) // can we loop again?
-                if (available) { goto loop }
-        fail:
-
-
-        This gives about a 5% gain on v8-regex, no change on Sunspider.

-        Bug 25202: Improve performance of repeated callbacks into the VM
-
-        Add the concept of a CachedCall to native code for use in Array
-        prototype and similar functions where a single callback function
-        is called repeatedly with the same number of arguments.
-
-        Used Array.prototype.filter as the test function and got a 50% win

-        dtoa.cpp segfaults with g++ 4.4.0
-
-        g++ 4.4.0 seems to be more strict about aliasing rules, so it

-        <rdar://problem/6657774>
-
-        r41508 actually exposed a pre-existing bug where we were not invalidating the result
-        register cache at jump targets.  This causes problems when condition loads occur in an
-        expression -- namely through the ?: and || operators.  This patch corrects these issues
-        by marking the target of all forward jumps as being a jump target, and then clears the
-        result register cache when ever it starts generating code for a targeted instruction.
-
-        I do not believe it is possible to cause this class of failure outside of a single
-        expression, and expressions only provide forward branches, so this should resolve this
-        entire class of bug.  That said i've included a test case that gets as close as possible
-        to hitting this bug with a back branch, to hopefully prevent anyone from introducing the
-        problem in future.

-        <rdar://problem/6354858> FastMallocZone's enumeration code reports fragmented administration space
-
-        The handling of MALLOC_ADMIN_REGION_RANGE_TYPE in FastMalloc's zone was incorrect.  It was attempting
-        to record the memory containing and individual span as an administrative region, when all memory
-        allocated via MetaDataAlloc should in fact be recorded.  This was causing memory regions allocated
-        via MetaDataAlloc to appear as "VM_ALLOCATE ?" in vmmap output.  They are now correctly reported as
-        "MALLOC_OTHER" regions associated with the JavaScriptCore FastMalloc zone.
-
-        Memory is allocated via MetaDataAlloc from two locations: PageHeapAllocator, and TCMalloc_PageMap{2,3}.
-        These two cases are handled differently.
-
-        PageHeapAllocator is extended to keep a linked list of memory regions that it has allocated.  The
-        first object in an allocated region contains the link to the previously allocated region. To record
-        the administrative regions of a PageHeapAllocator we can simply walk the linked list and record
-        each allocated region we encounter.
-
-        TCMalloc_PageMaps allocate memory via MetaDataAlloc to store each level of the radix tree.  To record
-        the administrative regions of a TCMalloc_PageMap we walk the tree and record the storage used for nodes
-        at each position rather than the nodes themselves.
-
-        A small performance improvement is achieved by coalescing adjacent memory regions inside the PageMapMemoryUsageRecorder
-        so that fewer calls in to the range recorder are necessary.  We further reduce the number of calls to the
-        range recorder by aggregating the in-use ranges of a given memory region into a local buffer before recording
-        them with a single call.  A similar approach is also used by AdminRegionRecorder.

-
-        The numeric sort optimization in r40993 generated bytecode for a function
-        without generating JIT code. This breaks an assumption in some parts of

-
-        In order to fix this, we simply generate JIT code whenever we check whether

-        in the case when the function is a numeric sort function, in which case it

-        Remove (/reduce) use of hard-wired register names from the JIT.
-        Currently there is no abstraction of registers used in the JIT,

-        register names makes the JIT less portable to other platforms,

-        When throwing an exception within an eval argument string, the dst parameter was
-        modified in the functions below and the return value for eval was altered. Changed
-        the emitNode call in JSC::ThrowNode::emitBytecode to use a temporary register
-        to store its results instead of dst. The JSC::FunctionCallResolveNode::emitBytecode
-        would load the function within the dst registry, also altering the result returned
-        by eval. Replaced it with another temporary.

-        platform-agnostic data types being the lower bun (in the form of the class AbstractMacroAssembler),
-        the plaform-specific code generation forming a big meaty patty of methods like 'add32',
-        'branch32', etc (MacroAssemblerX86), and finally topped off with the bun-lid of the
-        MacroAssembler class itself, providing covenience methods such as the stack peek & poke,
-        and backwards branch methods, all of which can be described in a platform independent
-        way using methods from the base class.  The AbstractMacroAssembler is templated on the
-        type of the assembler class that will be used for code generation, and the three layers
-        are held together with the cocktail stick of inheritance.
-
-        The above description is a slight simplification since the MacroAssemblerX86 is actually
-        formed from two layers (in effect giving us a kind on bacon double cheeseburger) - with the
-        bulk of methods that are common between x86 & x86-64 implemented in MacroAssemblerX86Common,
-        which forms a base class for MacroAssemblerX86 and MacroAssemblerX86_64 (which add the methods
-        specific to the given platform).
-
-        I'm landing these changes first without splitting the classes across multiple files,
-        I will follow up with a second patch to split up the file MacroAssembler.h.

-        Make the JSImmediate interface private.
-
-        All manipulation of JS values should be through the JSValuePtr class, not by using JSImmediate
-        directly.  The key missing methods on JSValuePtr are:
-
-            * isCell() - check for values that are JSCell*s, and as such where asCell() may be used.
-            * isInt32Fast() getInt32Fast() - fast check/access for integer immediates.
-            * isUInt32Fast() getUInt32Fast() - ditto for unsigned integer immediates.
-
-        The JIT is allowed full access to JSImmediate, since it needs to be able to directly
-        manipulate JSValuePtrs.  The Interpreter is provided access to perform operations directly
-        on JSValuePtrs through the new JSFastMath interface.
-
-        No performance impact.

-        On 32-bit platforms a JSValuePtr may represent a 31-bit signed integer.

-
-        The code to add a new constant (either number or string) to their respective

-        will be stored in the map, and will be resused if the same constant is encountered

-        <rdar://problem/6040850> JavaScript register file should use VirtualAlloc on Windows
-
-        Fairly simple, just reserve 4Mb of address space for the
-        register file, and then commit one section at a time.  We
-        don't release committed memory as we drop back, but then
-        mac doesn't either so this probably not too much of a 
-        problem.

-        Replace all uses of JSValue* with a new smart pointer type, JSValuePtr.
-        
-        A JavaScript value may be a heap object or boxed primitive, represented by a
-        pointer, or may be an unboxed immediate value, such as an integer.  Since a
-        value may dynamically need to contain either a pointer value or an immediate,
-        we encode immediates as pointer values (since all valid JSCell pointers are
-        allocated at alligned addesses, unaligned addresses are available to encode
-        immediates).  As such all JavaScript values are represented using a JSValue*.
-
-        This implementation is encumbered by a number of constraints.  It ties the
-        JSValue representation to the size of pointer on the platform, which, for
-        example, means that we currently can represent different ranges of integers
-        as immediates on x86 and x86-64.  It also prevents us from overloading the
-        to-boolean conversion used to test for noValue() - effectively forcing us
-        to represent noValue() as 0.  This would potentially be problematic were we
-        to wish to encode integer values differently (e.g. were we to use the v8
-        encoding, where pointers are tagged with 1 and integers with 0, then the
-        immediate integer 0 would conflict with noValue()).
-
-        This patch replaces all usage of JSValue* with a new class, JSValuePtr,
-        which encapsulates the pointer.  JSValuePtr maintains the same interface as
-        JSValue*, overloading operator-> and operator bool such that previous
-        operations in the code on variables of type JSValue* are still supported.
-
-        In order to provide a ProtectPtr<> type with support for the new value
-        representation (without using the internal JSValue type directly), a new
-        ProtectJSValuePtr type has been added, equivalent to the previous type
-        ProtectPtr<JSValue>.
-
-        This patch is likely the first in a sequence of three changes.  With the
-        value now encapsulated it will likely make sense to migrate the functionality
-        from JSValue into JSValuePtr, such that the internal pointer representation
-        need not be exposed.  Through migrating the functionality to the wrapper
-        class the existing JSValue should be rendered redundant, and the class is
-        likely to be removed (the JSValuePtr now wrapping a pointer to a JSCell).
-        At this stage it will likely make sense to rename JSValuePtr to JSValue.

-        <rdar://problem/6474110>
-
-        So this delightful bug was caused by our unwind code using a ScopeChain to perform
-        the unwind.  The ScopeChain would ref the initial top of the scope chain, then deref
-        the resultant top of scope chain, which is incorrect.
-
-        This patch removes the dependency on ScopeChain for the unwind, and i've filed
-        <https://bugs.webkit.org/show_bug.cgi?id=23144> to look into the unintuitive
-        ScopeChain behaviour.

-
-        The fix to this is to devirtualise get and put in a manner similar to
-        JSString and JSArray.  To do this I've added a ByteArray implementation
-        and JSByteArray wrapper to JSC.  We can then do vptr comparisons to

-
-        This devirtualisation improves performance by 1.5-2x in my somewhat ad

-        Bug 23037: Parsing and reparsing disagree on automatic semicolon insertion
-        <https://bugs.webkit.org/show_bug.cgi?id=23037>

-
-        Parsing and reparsing disagree about automatic semicolon insertion, so that a
-        function like
-
-        function() { a = 1, }
-
-        is parsed as being syntactically valid but gets a syntax error upon reparsing.
-        This leads to an assertion failure in Parser::reparse(). It is not that big of
-        an issue in practice, because in a Release build such a function will return
-        'undefined' when called.
-
-        In this case, we are not following the spec and it should be a syntax error.
-        However, unless there is a newline separating the ',' and the '}', WebKit would
-        not treat it as a syntax error in the past either. It would be a bit of work to
-        make the automatic semicolon insertion match the spec exactly, so this patch
-        changes it to match our past behaviour.
-
-        The problem is that even during reparsing, the Lexer adds a semicolon at the
-        end of the input, which confuses allowAutomaticSemicolon(), because it is
-        expecting either a '}', the end of input, or a terminator like a newline.

-        Fixes for the JIT's handling of JSImmediate values on x86-64.
-        On 64-bit systems, the code in JSImmediate.h relies on the upper
-        bits of a JSImmediate being a sign extension of the low 32-bits.
-        This was not being enforced by the JIT, since a number of inline
-        operations were being performed on 32-bit values in registers, and
-        when a 32-bit result is written to a register on x86-64 the value
-        is zero-extended to 64-bits.
-        
-        This fix honors previous behavoir.  A better fix in the long run
-        (when the JIT is enabled by default) may be to change JSImmediate.h
-        so it no longer relies on the upper bits of the pointer,... though
-        if we're going to change JSImmediate.h for 64-bit, we probably may
-        as well change the format so that the full range of 32-bit ints can
-        be stored, rather than just 31-bits.

-        <rdar://problem/6402499>
-
-        Before r38407, Structure::m_nameInPrevious was ref'd due to it being
-        stored in a PropertyMap. However, PropertyMaps are created lazily after
-        r38407, so Structure::m_nameInPrevious is not necessarily ref'd while
-        it is being used. Making it a RefPtr instead of a raw pointer fixes
-        the problem.
-
-        Unfortunately, the crash in the bug is rather intermittent, and it is
-        impossible to add an assertion in UString::Ref::ref() to catch this bug
-        because some users of UString::Rep deliberately zero out the reference
-        count. Therefore, there is no layout test accompanying this bug fix.

-        Add support to X86Assembler emitting instructions that access all 16 registers on x86-64.
-        Add a new formating class, that is reponsible for both emitting the opcode bytes and the
-        ModRm  bytes of an instruction in a single call; this can insert the REX byte as necessary
-        before the opcode, but has access to the register numbers to build the REX.

-        <https://bugs.webkit.org/show_bug.cgi?id=22828>
-
-        In order to remove the bytecode instruction stream after generating
-        native code, all inspection of bytecode instructions at runtime must
-        be removed. One particular instance of this is the special handling of

-        <rdar://problem/6309878> Need more granular control over allocation of executable memory (21783)
-        <https://bugs.webkit.org/show_bug.cgi?id=21783>
-
-        Add a new allocator for use by the JIT that provides executable pages, so
-        we can get rid of the current hack that makes the entire heap executable.
-
-        1-2% progression on SunSpider-v8, 1% on SunSpider.  Reduces memory usage as well!

-        Remove m_assembler from MacroAssembler::Jump.
-        Keeping a pointer allowed for some syntactic sugar - "link()" looks nicer
-        than "link(this)".  But maintaining this doubles the size of Jump, which
-        is even more unfortunate for the JIT, since there are many large structures

-        Bug 22504: Crashes during code generation occur due to refing of ignoredResult()
-        <https://bugs.webkit.org/show_bug.cgi?id=22504>
-
-        Since ignoredResult() was implemented by casting 1 to a RegisterID*, any
-        attempt to ref ignoredResult() results in a crash. This will occur in
-        code generation of a function body where a node emits another node with
-        the dst that was passed to it, and then refs the returned RegisterID*.
-
-        To fix this problem, make ignoredResult() a member function of
-        BytecodeGenerator that simply returns a pointe to a fixed RegisterID
-        member of BytecodeGenerator.

-        
-        The solution is to check for end of input before incrementing index,
-        to ensure that index is always <= length.
-        
-        As a side benefit, generateJumpIfEndOfInput can now use je instead of
-        jg, which should be slightly faster.

-        Polymorpic caching for get by id chain.  Similar to the polymorphic caching already implemented
-        for self and proto accesses (implemented by allowing multiple trampolines to be JIT genertaed,
-        and linked together) - the get by id chain caching is implemented as a genericization of the
-        proto list caching, allowing cached access lists to contain a mix of proto and proto chain
-        accesses (since in JS style inheritance hierarchies you may commonly see a mix of properties
-        being overridden on the direct prototype, or higher up its prototype chain).
-
-        In order to allow this patch to compile there is a fix to appease gcc 4.2 compiler issues
-        (removing the jumps between fall-through cases in privateExecute).
-        
-        This patch also removes redundant immediate checking from the reptach code, and fixes a related

-        Add support for (really) polymorphic caching of prototype accesses.
-        
-        If a cached prototype access misses, cti_op_get_by_id_proto_list is called.
-        When this occurs the Structure pointers from the instruction stream are copied
-        off into a new ProtoStubInfo object.  A second prototype access trampoline is
-        generated, and chained onto the first.  Subsequent missed call to
-        cti_op_get_by_id_proto_list_append, which append futher new trampolines, up to
-        PROTOTYPE_LIST_CACHE_SIZE (currently 4).  If any of the misses result in an
-        access other than to a direct prototype property, list formation is halted (or
-        for the initial miss, does not take place at all).
-
-        Separate fail case functions are provided for each access since this contributes
-        to the performance progression (enables better processor branch prediction).
-
-        Overall this is a near 5% progression on v8, with around 10% wins on richards
-        and deltablue.

-        A few more renames:
-
-        BytecodeInterpreter => Interpreter
-        WREC => JSC::WREC, removing JSC:: prefix in a lot of places
-        X86Assembler::copy => X86Assembler::executableCopy
-        AssemblerBuffer::copy => AssemblerBuffer::executableCopy
-        WRECFunction => WREC::RegExpFunction
-        OBJECT_OFFSET => FIELD_OFFSET
-        
-        Also:
-
-        Nixed use of OBJECT_OFFSET outside of CTI.cpp by making CTI a friend in more places.
-        Nixed X86:: and X86Assembler:: prefixes in a lot of places using typedefs

-        Reduce PropertyMap usage
-
-        From observation of StructureID statistics, it became clear that many
-        StructureID's were not being used as StructureIDs themselves, but rather
-        only being necessary as links in the transition chain.  Acknowledging this
-        and that PropertyMaps stored in StructureIDs can be treated as caches, that
-        is that they can be reconstructed on demand, it became clear that we could
-        reduce the memory consumption of StructureIDs by only keeping PropertyMaps
-        for the StructureIDs that need them the most.
-
-        The specific strategy used to reduce the number of StructureIDs with
-        PropertyMaps is to take the previous StructureIDs PropertyMap when initially
-        transitioning (addPropertyTransition) from it and clearing out the pointer 
-        in the process.  The next time we need to do the same transition, for instance
-        repeated calls to the same constructor, we use the new addPropertyTransitionToExistingStructure
-        first, which allows us not to need the PropertyMap to determine if the property
-        exists already, since a transition to that property would require it not already
-        be present in the StructureID.  Should there be no transition, the PropertyMap
-        can be constructed on demand (via materializePropertyMap) to determine if the put is a 
-        replace or a transition to a new StructureID.
-
-        Reduces memory use on Membuster head test (30 pages open) by ~15MB.

-        Bug 21943: Avoid needless reads of temporary values in CTI code
-        <https://bugs.webkit.org/show_bug.cgi?id=21943>
-
-        If an opcode needs to load a virtual register and a previous opcode left
-        the contents of that virtual register in a machine register, use the
-        value in the machine register rather than getting it from memory.
-
-        In order to perform this optimization, it is necessary to know the
-        jump tagets in the CodeBlock. For temporaries, the only problematic
-        jump targets are binary logical operators and the ternary conditional
-        operator. However, if this optimization were to be extended to local 
-        variable registers as well, other jump targets would need to be
-        included, like switch statement cases and the beginnings of catch
-        blocks.
-
-        This optimization also requires that the fast case and the slow case
-        of an opcode use emitPutResult() on the same register, which was chosen
-        to be eax, as that is the register into which we read the first operand
-        of opcodes. In order to make this the case, we needed to add some mov
-        instructions to the slow cases of some instructions.
-
-        This optimizaton is not applied whenever compileBinaryArithOp() is used
-        to compile an opcode, because different machine registers may be used to
-        store the final result. It seems possible to rewrite the code generation
-        in compileBinaryArithOp() to allow for this optimization.
-
-        This optimization is also not applied when generating slow cases,
-        because some fast cases overwrite the value of eax before jumping to the
-        slow case. In the future, it may be possible to apply this optimization
-        to slow cases as well, but it did not seem to be a speedup when testing
-        an early version of this patch.
-
-        This is a 1.0% speedup on SunSpider and a 6.3% speedup on the V8

-        - fix storage leak seen on buildbot
-
-        Some other cleanup too. The storage leak was caused by the fact
-        that HashTraits<CallIdentifier>::needsDestruction was false, so
-        the call identifier objects didn't get deleted.
-
-        * profiler/CallIdentifier.h:
-        
-        Added a default constructor to create empty call identifiers.
-
-        Changed the normal constructor to use const UString&
-        to avoid extra copying and reference count thrash.
-        
-        Removed the explicit copy constructor definition, since it's what
-        the compiler will automatically generate. (Rule of thumb: Either
-        you need both a custom copy constructor and a custom assignment
-        operator, or neither.)
-
-        Moved the CallIdentifier hash function out of the WTF namespace;
-        there's no reason to put it there.
-
-        Changed the CallIdentifier hash function to be a struct rather than
-        a specialization of the IntHash struct template. Having it be
-        a specialization made no sense, since CallIdentifier is not an integer,
-        and did no good.
-
-        Removed explicit definition of emptyValueIsZero in the hash traits,
-        since inheriting from GenericHashTraits already makes that false.
-
-        Removed explicit definition of emptyValue, instead relying on the
-        default constructor and GenericHashTraits.
-
-        Removed explicit definition of needsDestruction, because we want it
-        to have its default value: true, not false. This fixes the leak!
-
-        Changed constructDeletedValue and isDeletedValue to use a line number
-        of numeric_limits<unsigned>::max() to indicate a value is deleted.
-        Previously this used empty strings for the empty value and null strings
-        for the deleted value, but it's more efficient to use null for both.

-
-        For Windows, export explicit functions rather than exporting data for atomicallyInitializedStaticMutex.
-        
-        Exporting data from a DLL on Windows requires specifying __declspec(dllimport) in the header used by

-        Fixed Sampling Tool:
-            - Made CodeBlock sampling work with CTI
-            - Improved accuracy by unifying most sampling data into a single
-              32bit word, which can be written / read atomically.
-            - Split out three different #ifdefs for modularity: OPCODE_SAMPLING;
-              CODEBLOCK_SAMPLING; OPCODE_STATS.
-            - Improved reporting clarity

-        * VM/CTI.h: Updated CTI codegen to use the unified SamplingTool interface
-        for encoding samples. (This required passing the current vPC to a lot
-        more functions, since the unified interface samples the current vPC.)
-        Added hooks for writing the current CodeBlock* on function entry and
-        after a function call, for the sake of the CodeBlock sampler. Removed
-        obsolete hook for clearing the current sample inside op_end. Also removed
-        the custom enum used to differentiate flavors of op_call, since the
-        OpcodeID enum works just as well. (This was important in an earlier

-        * VM/Opcode.h: Upated for refactored #ifdefs. Added a little more padding,
-        to accomodate our more verbose opcode names.
-
-        * VM/SamplingTool.cpp:
-        (JSC::ScopeSampleRecord::sample): Only count a sample toward our total
-        if we actually record it. This solves cases where a CodeBlock will
-        claim to have been sampled many times, with reported samples that don't
-        match.
-
-        (JSC::SamplingTool::run): Read the current sample into a Sample helper
-        object, to ensure that the data doesn't change while we're analyzing it,
-        and to help decode the data. Only access the CodeBlock sampling hash
-        table if CodeBlock sampling has been enabled, so non-CodeBlock sampling
-        runs can operate with even less overhead.
-
-        (JSC::SamplingTool::dump): I reorganized this code a lot to print the
-        most important info at the top, print as a table, annotate and document

-        Fix hideous pathological case performance when looking up repatch info, bug #21727.
-
-        When repatching JIT code to optimize we look up records providing information about

-        The lookup was being performed using a linear scan of all such records.
-
-        (1) Split up the different types of reptach information.  This means we can search them

-        (2) In the case of property accesses, search with a binary chop over the data.
-        (3) In the case of calls, pass a pointer to the repatch info into the relink function.

-          improve performance by eliminating JSValue as a base class for JSCell
-
-        Remove casts from JSValue* to derived classes, replacing them with
-        calls to inline casting functions. These functions are also a bit
-        better than aidrect cast because they also do a runtime assertion.
-
-        Removed use of 0 as for JSValue*, changing call sites to use a
-        noValue() function instead.
-
-        Move things needed by classes derived from JSValue out of the class,
-        since the classes won't be deriving from JSValue any more soon.
-
-        I did most of these changes by changing JSValue to not be JSValue* any
-        more, then fixing a lot of the compilation problems, then rolling out
-        the JSValue change.

-        Optimize op_call by allowing call sites to be directly linked to callees.
-
-        For the hot path of op_call, CTI now generates a check (initially for an impossible
-        value), and the first time the call is executed we attempt to link the call directly
-        to the callee.  We can currently only do so if the arity of the caller and callee
-        match.  The (optimized) setup for the call on the hot path is linked directly to
-        the ctiCode for the callee, without indirection.
-        
-        Two forms of the slow case of the call are generated, the first will be executed the
-        first time the call is reached.  As well as this path attempting to link the call to
-        a callee, it also relinks the slow case to a second slow case, which will not continue
-        to attempt relinking the call.  (This policy could be changed in future, but for not
-        this is intended to prevent thrashing).
-
-        If a callee that the caller has been linked to is garbage collected, then the link
-        in the caller's JIt code will be reset back to a value that cannot match - to prevent
-        any false positive matches.

-        ~20% progression on deltablue & richards, >12% overall reduction in v8-tests
-        runtime, one or two percent progression on sunspider.

-        Don't create intermediate StructureIDs for builtin objects

-        First step in reduce number of StructureIDs created when initializing the

-
-        - In order to avoid creating the intermediate StructureIDs use the new putDirectWithoutTransition

-
-        StructureID::getEnumerablePropertyNames() ends up calling back to itself
-        via JSObject::getPropertyNames(), which causes the PropertyNameArray to
-        be cached twice. This leads to a memory leak in almost every use of
-        JSObject::getPropertyNames() on an object. The fix here is based on a
-        suggestion of Sam Weinig.

-        This patch also fixes every StructureID leaks that occurs while running

-
-        After r37324, an Arguments object does not mark an associated activation
-        object. This change was made because Arguments no longer directly used
-        the activation object in any way. However, if an activation is torn off,
-        then the backing store of Arguments becomes the register array of the
-        activation object. Arguments directly marks all of the arguments, but
-        the activation object is being collected, which causes its register
-        array to be freed and new memory to be allocated in its place.
-
-        Unfortunately, it does not seem possible to reproduce this issue in a
-        layout test.

-          Bug 21403: use new CallFrame class rather than Register* for call frame manipulation
-
-        Add CallFrame as a synonym for ExecState. Arguably, some day we should switch every
-        client over to the new name.
-
-        Use CallFrame* consistently rather than Register* or ExecState* in low-level code such
-        as Machine.cpp and CTI.cpp. Similarly, use callFrame rather than r as its name and use
-        accessor functions to get at things in the frame.
-
-        Eliminate other uses of ExecState* that aren't needed, replacing in some cases with
-        JSGlobalData* and in other cases eliminating them entirely.

-        <https://bugs.webkit.org/show_bug.cgi?id=21364>
-
-        Use information from the parser to detect whether an activation is
-        needed or 'arguments' is used, and emit explicit instructions to tear
-        them off before op_ret. This allows a branch to be removed from op_ret
-        and simplifies some other code. This does cause a small change in the
-        behaviour of 'f.arguments'; it is no longer live when 'arguments' is not
-        mentioned in the lexical scope of the function.
-
-        It should now be easy to remove the OptionaCalleeActivation slot in the
-        call frame, but this will be done in a later patch.

-        Preliminary step toward dynamic recompilation: Standardized and
-        simplified the parsing interface.
-        
-        The main goal in this patch is to make it easy to ask for a duplicate
-        compilation, and get back a duplicate result -- same source URL, same
-        debugger / profiler ID, same toString behavior, etc.
-

-        encompasses a SourceProvider, a range in that provider, and a starting
-        line number.
-
-        A SourceProvider now encompasses a source URL, and *is* a source ID,

-        <https://bugs.webkit.org/show_bug.cgi?id=21123>
-
-        Make the 'arguments' object not require a JSActivation. We store the
-        'arguments' object in the OptionalCalleeArguments call frame slot. We
-        need to be able to get the original 'arguments' object to tear it off
-        when returning from a function, but 'arguments' may be assigned to in a
-        number of ways.
-
-        Therefore, we use the OptionalCalleeArguments slot when we want to get
-        the original activation or we know that 'arguments' was not assigned a
-        different value. When 'arguments' may have been assigned a new value,
-        we use a new local variable that is initialized with 'arguments'. Since
-        a function parameter named 'arguments' may overwrite the value of
-        'arguments', we also need to be careful to look up 'arguments' in the
-        symbol table, so we get the parameter named 'arguments' instead of the
-        local variable that we have added for holding the 'arguments' object.
-
-        This is a 19.1% win on the V8 Raytrace benchmark using the SunSpider
-        harness, and a 20.7% win using the V8 harness. This amounts to a 6.5%

-        Improve performance of CTI on windows.

-        Currently on platforms where the compiler doesn't allow us to safely

-        Add support for reusing temporary JSNumberCells.  This change is based on the observation
-        that if the result of certain operations is a JSNumberCell and is consumed by a subsequent
-        operation that would produce a JSNumberCell, we can reuse the object rather than allocating
-        a fresh one.  E.g. given the expression ((a * b) * c), we can statically determine that
-        (a * b) will have a numeric result (or else it will have thrown an exception), so the result
-        will either be a JSNumberCell or a JSImmediate.
-
-        This patch changes three areas of JSC:
-            * The AST now tracks type information about the result of each node.
-            * This information is consumed in bytecode compilation, and certain bytecode operations
-              now carry the statically determined type information about their operands.
-            * CTI uses the information in a number of fashions:
-                * Where an operand to certain arithmetic operations is reusable, it will plant code
-                  to try to perform the operation in JIT code & reuse the cell, where appropriate.
-                * Where it can be statically determined that an operand can only be numeric (typically
-                  the result of another arithmetic operation) the code will not redundantly check that
-                  the JSCell is a JSNumberCell.
-                * Where either of the operands to an add are non-numeric do not plant an optimized
-                  arithmetic code path, just call straight out to the C function.

-        <https://bugs.webkit.org/show_bug.cgi?id=19968>
-
-        Finally found the cause of this accursed issue.  It is triggered
-        by synchronous creation of a new global object from JS.  The new
-        global object resets the timer state in this execution group's
-        Machine, taking timerCheckCount to 0.  Then when JS returns the
-        timerCheckCount is decremented making it non-zero.  The next time
-        we execute JS we will start the timeout counter, however the non-zero
-        timeoutCheckCount means we don't reset the timer information. This
-        means that the timeout check is now checking the cumulative time
-        since the creation of the global object rather than the time since
-        JS was last entered.  At this point the slow script dialog is guaranteed
-        to eventually be displayed incorrectly unless a page is loaded
-        asynchronously (which will reset everything into a sane state).
-
-        The fix for this is rather trivial -- the JSGlobalObject constructor
-        should not be resetting the machine timer state.
-
-        * VM/Machine.cpp:
-        (JSC::Machine::Machine):
-          Now that we can't rely on the GlobalObject initialising the timeout
-          state, we do it in the Machine constructor.

-        'delete' statement. This patch also speeds up access to the 'arguments'
-        object slightly, but it still does not use the array fast path for
-        indexed access that exists for many opcodes.
-
-        This is about a 20% improvement on the V8 Raytrace benchmark, and a 1.5%
-        improvement on the Earley-Boyer benchmark, which gives a 4% improvement
-        overall.

-        - a ~1.6MB save on libwebkit.so in debug.
-
-        It is a wash on Sunspider and a small win on Dromaeo (not sure it is relevant).
-        On the whole, it should be a small win as we reduce the compiled code size and the only
-        new function call should be inlined by the compiler.

-        r36417 and r36427 caused an get_by_id opcode to be emitted before the

-        the prototype property. Unfortunately, this regressed some tests dealing

-        - enable polymorphic inline caching of properties of primitives
-        
-        1.012x speedup on SunSpider.
-
-        We create special structure IDs for JSString and
-        JSNumberCell. Unlike normal structure IDs, these cannot hold the
-        true prototype. Due to JS autoboxing semantics, the prototype used
-        when looking up string or number properties depends on the lexical
-        global object of the call site, not the creation site. Thus we
-        enable StructureIDs to handle this quirk for primitives.
-        
-        Everything else should be straightforward.

-        Bug 20704: Replace the KJS namespace
-        <https://bugs.webkit.org/show_bug.cgi?id=20704>
-
-        Rename the KJS namespace to JSC. There are still some uses of KJS in
-        preprocessor macros and comments, but these will also be changed some
-        time in the near future.

-        Jump through the necessary hoops required to make MSVC cooperate with SFX
-
-        We now explicitly declare the calling convention on all cti_op_* cfunctions,
-        and return int instead of bool where appropriate (despite the cdecl calling
-        convention seems to state MSVC generates code that returns the result value
-        through ecx).  SFX behaves slightly differently under MSVC, specifically it
-        stores the base argument address for the cti_op_* functions in the first
-        argument, and then does the required stack manipulation through that pointer.
-        This is necessary as MSVC's optimisations assume they have complete control
-        of the stack, and periodically elide our stack manipulations, or move
-        values in unexpected ways.  MSVC also frequently produces tail calls which may
-        clobber the first argument, so the MSVC path is slightly less efficient due
-        to the need to restore it.

-        Zero-cost exception handling.  This patch takes the exception checking
-        back of the hot path.  When an exception occurs in a Machine::cti*
-        method, the return address to JIT code is recorded, and is then
-        overwritten with a pointer to a trampoline routine.  When the method
-        returns the trampoline will cause the cti_vm_throw method to be invoked.
-
-        cti_vm_throw uses the return address preserved above, to discover the
-        vPC of the bytecode that raised the exception (using a map build during
-        translation).  From the VPC of the faulting bytecode the vPC of a catch
-        routine may be discovered (unwinding the stack where necesary), and then
-        a bytecode address for the catch routine is looked up.  Final cti_vm_throw
-        overwrites its return address to JIT code again, to trampoline directly
-        to the catch routine.
-        
-        cti_op_throw is handled in a similar fashion.

-        (KJS::CodeGenerator::CodeGenerator): Used BatchedTransitionOptimizer to

-        that tried to do the same in a more limited way.
-
-        * VM/CodeGenerator.h: Moved IdentifierRepHash to the KJS namespace since

-
-        * kjs/BatchedTransitionOptimizer.h: Added. New class that allows host

-
-        * kjs/StructureID.cpp: Added a new transition *away* from dictionary

-        First cut at inline caching for access to vanilla JavaScript properties.
-        
-        SunSpider says 4% faster. Tests heavy on dictionary-like access have
-        regressed a bit -- we have a lot of room to improve in this area,
-        but this patch is over-ripe as-is.
-        
-        JSCells now have a StructureID that uniquely identifies their layout,
-        and holds their prototype.
-        
-        JSValue::put takes a PropertySlot& argument, so it can fill in details
-        about where it put a value, for the sake of caching.
-
-        * VM/CodeGenerator.cpp:
-        (KJS::CodeGenerator::CodeGenerator): Avoid calling removeDirect if we
-        can, since it disables inline caching in the global object. This can
-        probably improve in the future.
-
-        * kjs/JSGlobalObject.cpp: Nixed reset(), since it complicates caching, and
-        wasn't really necessary.
-
-        * kjs/JSObject.cpp: Tweaked getter / setter behavior not to rely on the
-        IsGetterSetter flag, since the flag was buggy. This is necessary in order
-        to avoid accidentally accessing a getter / setter as a normal property.
-        
-        Also changed getter / setter creation to honor ReadOnly, matching Mozilla.

-        * kjs/PropertyMap.cpp: Nixed clear(), since it complicates caching and

-
-        r36006 changed stringProtoFuncSubstr() so that it is uses the more
-        efficient jsSubstring(), rather than using UString::substr() and then
-        calling jsString(). However, the change did not account for the case

-        it doesn't need to look at any data members.
-        (KJS::UString::expandCapacity): Use a non-inline function, makeNull, to
-        set the rep to null in failure cases. This avoids adding a PIC branch for
-        the normal case when there is no failure.
-        (KJS::UString::expandPreCapacity): Ditto.
-        (KJS::UString::UString): Ditto.
-        (KJS::concatenate): Refactored the concatenation constructor into this
-        separate function. Calling the concatenation constructor was leading to
-        an extra branch because of the in-charge vs. not-in-charge versions not
-        both being inlined, and this was showing up as nearly 1% on Shark. Also
-        added a special case for when the second string is a single character,
-        since it's a common idiom to build up a string that way and we can do
-        things much more quickly, without involving memcpy for example. Also
-        adopted the non-inline function, nullRep, for the same reason given for
-        makeNull above.

-        (KJS::operator==): Added special cases so we can compare single-character

-        <rdar://problem/6150322> In Gmail, a crash occurs at KJS::Machine::privateExecute() when applying list styling to text after a quote had been removed
-        <https://bugs.webkit.org/show_bug.cgi?id=20386>
-
-        This crash was caused by "depth()" incorrectly determining the scope depth 
-        of a 0 depth function without a full scope chain.  Because such a function
-        would not have an activation the depth function would return the scope depth
-        of the parent frame, thus triggering an incorrect unwind.  Any subsequent 
-        look up that walked the scope chain would result in incorrect behaviour,
-        leading to a crash or incorrect variable resolution.  This can only actually
-        happen in try...finally statements as that's the only path that can result in
-        the need to unwind the scope chain, but not force the function to need a
-        full scope chain.
-
-        The fix is simply to check for this case before attempting to walk the scope chain.
