        Revision 35651, despite being a rather trivial change, introduced a
        large regression on the regexp-dna SunSpider test. This regression
        stemmed from an increase in the size of CodeBlock::dump(). There is
        no reason for this method (and several related methods) to be compiled
        in non-debug builds with the sampling tool disabled. This patch
        conditionally compiles them, reversing the regression on SunSpider.

        Improve performance of arithmetic operators

        Added a fast (non-virtual) mechanism to determine if a non-immediate JSValue*
        is a JSNumberCell.  We then use this to allow improved specialisation in many
        arithmetic operators.  SunSpider reports a 2.5% progression overall, with greater
        than 10% progressions on a number of arithmetic heavy tests.

        Bug 19359: JavaScriptCore behaves differently from FF2/3 and IE when handling context in catch statement
        <https://bugs.webkit.org/show_bug.cgi?id=19359>

        Make our catch behave like Firefox and IE, we do this by using a StaticScopeObject
        instead of a generic JSObject for the scope node.  We still don't make use of the
        fact that we have a static scope inside the catch block, so the internal performance
        of the catch block is not improved, even though technically it would be possible to
        do so.

        Fix the build system for the Qt port.

        Recent JavaScriptCore changes require the addition of JavaScriptCore/API to the
        include search path. With a build process that combines JavaScriptCore and
        WebCore in one build process/Makefile the existance of
        JavaScriptCore/API/Node.h and WebCore/dom/Node.h causes include conflicts.

        This commit solves this by introducing a separate build of JavaScriptCore into
        a static library.

        As a result of the split-up a race-condition due to broken dependencies of
        regular source files to header files of generated sources showed up very
        frequently when doing parallel builds (which the buildbot does). This commit at
        the same time tries to address the dependency problem by making the
        addExtraCompiler() function also generate a pseudo extra compiler that
        represents the header file output, so that qmake is aware of the creation of
        the header file for dependency calculation.

        At the same time I removed a lot of cruft from the pro files to ease maintenance.

        JSClassRef is created context-free, but gets infatuated with the first context it sees.

        The implicit API contract is that JSClassRef can be used with any context on any thread.
        This no longer worked, because UStrings in the class were turned into per-context

        Next step toward putting doubles in registers: Prepare the Register class
        and its clients for registers that don't contain JSValue*s.
        
        This means a few things:
        
        1. Register::jsValue() clients, including ArgList clients, must now supply
        an ExecState* when accessing an entry in an ArgList, in case the entry
        will need to create a JSValue* on the fly.
        
        2. Register clients that definitely don't want to create a JSValue* on
        the fly now use different APIs: getJSValue() for clients that know
        the register contains a JSValue*, and v() for clients who just want a
        void*.
        
        3. I had to change some headers around in order to resolve dependency
        problems created by using a Register in the ArgList header.

        First step toward putting doubles in registers: Turned Register into a
        proper abstraction layer. It is no longer possible to cast a Register
        to a JSValue*, or a Register& to a JSValue*&, or to access the union
        inside a Register directly.
        
        SunSpider reports no change.
        
        In support of this change, I had to make the following mechanical changes
        in a lot of places:
        
        1. Clients now use explicit accessors to read data out of Registers, and
        implicit copy constructors to write data into registers.
        
        So, assignment that used to look like
        
            x.u.jsValue = y;
        
        now looks like
        
            x = y;
            
        And access that used to look like
        
            x = y.u.jsValue;
        
        now looks like
        
            x = y.jsValue();

        2. I made generic flow control specific in opcodes that made their flow
        control generic by treating a Register& as a JSValue*&. This had the
        added benefit of removing some exception checking branches from immediate
        number code.

        3. I beefed up PropertySlot to support storing a Register* in a property
        slot. For now, only JSVariableObject's symbolTableGet and symbolTablePut
        use this functionality, but I expect more clients to use it in the future.

        way to label mapped regions is to use a VM tag.

        When the profiler is running it gathers information and creates a
        Profile.  After it finishes the Profile can be sorted and have other

        REGRESSION (r34907): Gmail crashes in JavaScriptCore code while editing drafts
        
        I was never able to reproduce this issue, but Cameron could, and he says

        The crash seems tied to a timer or event handler callback. In such a case,
        the sole reference to the global object may be in the current call frame,
        so we can't depend on the global object to mark the call frame area in
        the register file.
        
        The new GC marking rule is: the global object is not responsible for
        marking the whole register file -- it's just responsible for the globals
        section it's tied to. The heap is responsible for marking the call frame area.

        Bug 18626: SQUIRRELFISH: support the "slow script" dialog <https://bugs.webkit.org/show_bug.cgi?id=18626>
        <rdar://problem/5973931> Slow script dialog needs to be reimplemented for squirrelfish

        Adds support for the slow script dialog in squirrelfish.  This requires the addition
        of three new op codes, op_loop, op_loop_if_true, and op_loop_if_less which have the
        same behaviour as their simple jump equivalents but have an additional time out check.

        Additional assertions were added to other jump instructions to prevent accidentally
        creating loops with jump types that do not support time out checks.

        Sunspider does not report a regression, however this appears very sensitive to code
        layout and hardware, so i would expect up to a 1% regression on other systems.

        Part of this required moving the old timeout logic from JSGlobalObject and into Machine
        which is the cause of a number of the larger diff blocks.

        One RegisterFile to rule them all!
        
        SunSpider reports a 0.2% speedup.

        This patch removes the RegisterFileStack abstraction and replaces it with
        a single register file that
        
        (a) allocates a fixed storage area, including a fixed area for global
        vars, so that no operation may cause the register file to reallocate
        
        and

        (b) swaps between global storage areas when executing code in different 
        global objects.
        
        This patch also changes the layout of the register file so that all call
        frames, including call frames for global code, get a header. This is
        required to support re-entrant global code. It also just makes things simpler.
        
        * VM/CodeGenerator.cpp:
        (KJS::CodeGenerator::addGlobalVar): New function. Differs from addVar in
        that
        
        (a) global vars don't contribute to a CodeBlock's numLocals count, since
        global storage is fixed and allocated at startup
        
        and
        
        (b) references to global vars get shifted to elide intermediate stack
        between "r" and the global storage area.
        
        * VM/Machine.cpp:
        (KJS::Machine::dumpRegisters): Updated this function to match the new
        register file layout, and added the ability to dump exact identifiers
        for the different parts of a call frame.
        
        (KJS::Machine::unwindCallFrame): Updated this function to match the new
        register file layout.
         
        (KJS::Machine::execute): Updated this function to initialize a call frame
        header for global code, and to swap global storage areas when switching
        to execution in a new global object.
        
        (KJS::Machine::privateExecute): Got rid of "safeForReentry" and re-reading
        of registerBase because the register file is always safe for reentry now,
        and registerBase never changes.
        
        * VM/Machine.h: Moved the call frame header enum from Machine to RegisterFile,
        to resolve a header dependency problem (a good sign that the enum belonged
        in RegisterFile all along!)

        * VM/RegisterFile.cpp:
        * VM/RegisterFile.h: Changed RegisterFile to mmap a fixed size register
        area. This allows us to avoid re-allocting the register file later on.
        Instead, we rely on the OS to allocate physical pages to the register
        file as necessary.

        * VM/RegisterFileStack.cpp: Removed. Tada!
        * VM/RegisterFileStack.h: Removed. Tada!

        * kjs/DebuggerCallFrame.cpp: Updated this class to match the new
        register file layout, greatly simplifying it in the process.

        * kjs/JSActivation.h:
        * kjs/JSActivation.cpp: Moved some of this logic up to JSVariableObject,
        since the global object now needs to be able to tear off its registers
        just like the activation object.

        * kjs/JSFunction.cpp: No need to fiddle with the register file anymore.

        * kjs/JSGlobalObject.h:
        * kjs/JSGlobalObject.cpp: Updated JSGlobalObject to support moving its
        global storage area into and out of the register file.

        * kjs/PropertySlot.cpp: No need to fiddle with the register file anymore.

        * kjs/collector.cpp: Renamed markStackObjectConservatively to
        markConservatively, since we don't just mark stack objects this way.
        
        Also, added code to mark the machine's register file.

        * kjs/config.h: Moved some platforms #defines from here...

        - work toward https://bugs.webkit.org/show_bug.cgi?id=19721

        More preparation toward making functions work on primitive types without
        creating wrapper objects. No speedup this time, but prepares for a future
        speedup without slowing things down.

        SunSpider reports no change.

        - Eliminated the implementsCall, callAsFunction and construct virtual
          functions from JSObject. Instead, the CallData and ConstructData for
          a native function includes a function pointer that the caller can use
          directly. Changed all call sites to use CallData and ConstructData.

        - Changed the "this" argument to native functions to be a JSValue rather
          than a JSObject. This prepares us for passing primitives into these
          functions. The conversion to an object now must be done inside the
          function. Critically, if it's a function that can be called on a DOM
          window object, then we have to be sure to call toThisObject on the
          argument before we use it for anything even if it's already an object.

        - Eliminated the practice of using constructor objects in the global
          object to make objects of the various basic types. Since these
          constructors can't be replaced by script, there's no reason to involve
          a constructor object at all. Added functions to do the construction
          directly.

        - Made some more class members private and protected, including virtual
          function overrides. This can catch code using unnecessarily slow virtual
          function code paths when the type of an object is known statically. If we
          later find a new reason use the members outside the class it's easy to
          make them public again.

        - Moved the declarations of the native implementations for functions out
          of header files. These can have internal linkage and be declared inside
          the source file.

        - Changed PrototypeFunction to take function pointers with the right
          arguments to be put directly into CallData. This eliminates the
          need to have a separate PrototypeReflexiveFunction, and reveals that the
          real purpose of that class included something else specific to eval --
          storage of a cached global object. So renamed PrototypeReflexiveFunction
          to GlobalEvalFunction.

        * JavaScriptCore.exp:

        Windows and Qt build fixes.

        * kjs/collector.h: 
        * kjs/collector.cpp:
        (KJS::Heap::Heap):
        Wrapped m_pagesize in #if PLATFORM(UNIX), which should better match the sequence of #elifs
        in allocateBlock(). Changed MIN_ARRAY_SIZE to be explicitly size_t, as this type is different
        on different platforms.

        Bug 19596: LEAK: Gmail leaks SegmentedVector<RegisterID>
        <https://bugs.webkit.org/show_bug.cgi?id=19596>

        When growing SegmentedVector, we start adding segments at the position
        of the last segment, overwriting it. The destructor frees allocated
        segments starting at the segment of index 1, because the segment of
        index 0 is assumed to be the initial inline segment. This causes a leak
        of the segment that is referenced by index 0. Modifying grow() so that
        it starts adding segments at the position after the last segment fixes
        the leak.

        Since the initial segment is a special case in the lookup code, this
        bug never manifested itself via incorrect results.

        Slight cleanup to the SymbolTableEntry class.
        
        Renamed isEmpty to isNull, since we usually use "empty" to mean "holds
        the valid, empty value", and "null" to mean "holds no value".
        
        Changed an "== 0" to a "!", to match our style guidelines.
        
        Added some ASSERTs to verify the (possibly questionable) assumption that
        all register indexes will have their high two bits set. Also clarified a
        comment to make that assumption clear.

        Bug 19484: More instructions needs to use temporary registers
        <https://bugs.webkit.org/show_bug.cgi?id=19484>

        Fix codegen for all binary operations so that temporaries are used if
        necessary. This was done by making BinaryOpNode and ReverseBinaryOpNode
        subclasses of ExpressionNode, and eliminating the custom emitCode()
        methods for the individual node classes.

        This only adds 3 new instructions to SunSpider code, and there is no
        difference in SunSpider execution time.

        the JSObject class to the JSCell class. Also, since the caller no longer knows
        the identity of the "original object", which is used by JavaScript-function
        based getters, changed the PropertySlot class so the original object is
        already stored in the slot when getOwnPropertySlot is called, if the caller
        intends to call getValue.

        This affected the old interpreter code enough that the easiest thing for me
        was to just delete it. While I am not certain the mysterious slowdown is not
        still occurring, the net change is definitely a significant speedup.

        (KJS::JSValue::get): Added. Here because it calls through to JSObject.
        A version of JSObject::get that also handles the other types of JSValue
        by creating the appropriate wrapper. Saves the virtual call to toObject.

        as the "this" object, which will be set to the original object by the new

        not do this, but needed to so we can properly handle the activation object
        like the other similar code paths.

        * kjs/property_slot.h:
        (KJS::PropertySlot::PropertySlot): Added a constructor that takes a base
        object. In debug builds, set the base to 0 if you don't pass one.
        (KJS::PropertySlot::getValue): Don't take or pass the originalObject.
        (KJS::PropertySlot::setValueSlot): Don't take a base object, and clear the
        base object in debug builds.
        (KJS::PropertySlot::setGetterSlot): Ditto.

        (KJS::PropertySlot::setUngettable): Ditto.
        (KJS::PropertySlot::slotBase): Assert that a base object is present.
        This will fire if someone actually calls the get function without having
        passed in a base object and the getter needs it.
        (KJS::PropertySlot::setBase): Added. Used by the code that implements
        toObject so it can supply the original object after the fact.
        (KJS::PropertySlot::clearBase): Added. Clears the base, but is debug-only
        code because it's an error to fetch the base if you don't have a guarantee
        it was set.

        the various PropertySlot functions that no longer take them.

        * kjs/value.cpp:
        (KJS::JSCell::getOwnPropertySlot): Added. Calls toObject and then sets the slot.
        This function has to always return true, because the caller can't walk the prototype
        chain. Because of that, we do a getPropertySlot, not getOwnPropertySlot, which works
        for the caller. This is private, only called by getOwnPropertySlotInternal.
        (KJS::JSCell::put): Added. Calls toObject and then put.
        (KJS::JSCell::toThisObject): Added. Calls toObject.

        * kjs/value.h: Added get, put, and toThisObject to both JSValue
        and JSCell. These take care of the toObject operation without an additional virtual
        function call, and so make the common "already an object" case faster.

        * wtf/AlwaysInline.h: Moved the UNLIKELY macro here for now. Maybe we can find a
        better place later, or rename this header.

        (KJS::Profile::stopProfiling): stopProfiling no longer needs the time

        * profiler/Profile.h:
        (KJS::Profile::focus): Instead of taking a CallIdentifier that the caller
        would have to create, now focus() takes a ProfileNode that they should
        already have a reference to and focus() can extract the CallIdentifier
        from it.
        * profiler/ProfileNode.cpp: Create actual and visible versions fo the
        total and self times for focus and exclude.  Also add a head node
        reference so that nodes can get information from their head.
        (KJS::ProfileNode::ProfileNode):

        variables and set the visual ones to the actual ones, so that without any
        changes to the visual versions of these variables, their times will match
        the actual times.
        (KJS::ProfileNode::focus): Now focus() has a bool to force it's children
        to be visible if this node is visible.  If this node does not match the
        CallIdentifier being focused then the visibleTotalTime is only updated if
        one or more of it's children is the CallIdentifier being focused.

        <https://bugs.webkit.org/show_bug.cgi?id=19110>

        Correct a comedy of errors present in my original patch to "fix"
        exceptions occurring midway through pre and post increment. This
        solution is cleaner than the original, doesn't need the additional
        opcodes, and as an added benefit does not break Google Maps.

        Sunspider reports a 0.4% progression.

        Track the offset of the last call frame in the ExecState, so we can

        Also, record numLocals, the sum of numVars + numParameters, in each code
        block, to make updates to the ExecState a little cheaper than they
        would be otherwise.

        Put a limit on the level of reentry recursion.  128 levels of re-entrant recursion
        seems reasonable as it is greater than the old eval limit, and a long way short of

        Bug 18672: SQUIRRELFISH: codegen fails with a large number of temporaries
        <https://bugs.webkit.org/show_bug.cgi?id=18672>

        Add a SegmentedVector type, which provides a Vector<T> which maintains
        existing memory locations during resize.  This allows dynamically sizing
        local, temporary and label "vectors" in CodeGenerator.

        A little refactoring in preparation for supporting 'arguments'.
        
        Fixes 2 regression tests.

        SunSpider reports no change.        

        We now check the activation register, instead of the codeBlock, to
        determine whether we need to tear off the activation. This is to support
        "f.arguments", which will create an activation/arguments pair for f,
        even though the needsFullScopeChain flag is false for f's codeBlock.
        
        The test fixes resulted from calling initializeCallFrame for re-entrant
        function code, instead of initializing (not enough) parts of the call
        frame by hand.

        Fixed ScopeChainNode lifetime problems:
        
        (1) In "with" and "catch" scopes, we would construct a ScopeChain
        object and then jump across its destructor, leaking the ScopeChainNode
        we had pushed.

        (2) In global and eval scopes, we would fail to initially ref
        "scopeChain", causing us to overrelease it later. Now that we ref
        "scopeChain" properly, we also need to deref it when the script
        terminates.

        SunSpider reports a .2% regression, but an earlier round of ScopeChain
        refactoring was a .4% speedup, so there.

        Bug 18619: Support continue, break, and return in try .. finally blocks
        <https://bugs.webkit.org/show_bug.cgi?id=18619>

        This patch replaces the current partial finally support (which uses code
        duplication to achieve what it does) with a subroutine based approach.
        This has a number of advantages over code duplication:
          * Reduced code size
          * Simplified exception handling as the finaliser code only exists in 
            one place, so no "magic" is needed to get the correct handler for a 
            finaliser.
          * When we support instruction to line number mapping we won't need to
            worry about the dramatic code movement caused by duplication

        On the downside it is necessary to add two new opcodes, op_jsr and op_sret
        to enter and exit the finaliser subroutines, happily SunSpider reports
        a performance progression (gcc amazes me) and ubench reports a wash.

        While jsr and sret provide a mechanism that allows us to enter and exit
        any arbitrary finaliser we need to, it was still necessary to increase
        the amount of information tracked when entering and exiting both finaliser
        scopes and dynamic scopes ("with").  This means "scopeDepth" is now
        the combination of "finaliserDepth" and "dynamicScopeDepth".  We also
        now use a scopeContextStack to ensure that we pop scopes and execute
        finalisers in the correct order.  This increases the cost of "with" nodes
        during codegen, but it should not be significant enough to effect real
        world performance and greatly simplifies codegen for return, break and
        continue when interacting with finalisers.

        This is somewhat more convoluted than the simple hadException checks

        - fix codegen handling of dst registers
        
        1.006x speedup (not sure why).
        
        Most emitCode functions take an optional "dst" parameter that says
        where the output of the instruction should be written. I made some
        functions for convenient handling of the dst register:

        * VM/CodeGenerator.h:
        (KJS::CodeGenerator::tempDestination): Takes the dst register. Returns it if
        it is not null and is a temporary, otherwise allocates a new temporary. This is
        intended for cases where an intermediate value might be written into the dst

        (KJS::CodeGenerator::finalDestination): Takes the dst register and an optional
        register that was used as a temp destination. Picks the right thing for the final
        output. Intended to be used as the output register for the instruction that generates
        the final value of a particular node.
        
        (KJS::CodeGenerator::moveToDestinationIfNeeded): Takes dst and a
        RegisterID; moves from the register to dst if dst is defined and
        different from the register. This is intended for cases where the
        result of a node is already in a specific register (likely a
        local), and so no code needs to be generated unless a specific
        destination has been requested, in which case a move is needed.
        
        I also applied these methods throughout emitCode functions. In
        some cases this was just cleanup, in other cases I fixed actual
        codegen bugs. Below I have given specific comments for the cases
        where I believe I fixed a codegen bug, or improved quality of codegen.

        (KJS::ResolveNode::emitCode): Now avoids emitting a mov when dst
        is the same as the local regiester, in the local var case (the
        unlikely case of "x = x");

        codegen which can incorrectly write an intermediate value into the
        dst register even when that is a local. I added convenience

        Fix two bugs when throwing exceptions from re-entrant JS calls:
        
        (1) Don't shrink the register file to 0, since our caller may still
        be using it.
        
        (2) In case of exception, return jsNull() instead of 0 because,
        surprisingly, some JavaScriptCore clients rely on a function's return
        value being safe to operate on even if the function threw an exception.
        
        Also:
        
        - Changed FunctionImp::callAsFunction to honor the new semantics of
        exceptions not returning 0.
        
        - Renamed "handlerPC" to "handlerVPC" to match other uses of "VPC".
        
        - Renamed "exceptionData" to "exceptionValue", because "data" seemed to

        - Merged prepareException into throwException, since throwException was
        its only caller, and it seemed weird that throwException didn't take
        an exception as an argument.

        Re-entrant execution of function code (global code -> built-in function
        -> JS function):
        
        Miraculously, sunspider --squirrelfish does not seem to complain.

        A re-entrant function call is the same as a normal function call with
        one exception: the re-entrant call leaves everything except for
        CallerCodeBlock in the call frame header uninitialized, since the call
        doesn't need to return to JS code. (It sets CallerCodeBlock to 0, to
        indicate that the call shouldn't return to JS code.)
        
        Also fixed a few issues along the way:
        
        - Fixed two bugs in the read-write List implementation that caused
        m_size and m_buffer to go stale.
        
        - Changed native call code to update "r" *before* setting the return
        value, since the call may in turn call JS code, which changes the value
        of "r".
        
        - Migrated initialization of "r" outside of Machine::privateExecute,
        because global code and function code initialize "r" differently.
        
        - Migrated a codegen warning from Machine::privateExecute to the wiki.

        - initial preparatory work for JS constructors
        
        1) Allocate registers for the returnInfo block and "this" value when generating code for
        op_construct. These are not used yet, but the JS branch of op_construct will use them.
        
        2) Adjust argc and argv appropriately for native constructor calls.
        
        3) Assign return value in a more straightforward way in op_ret since this is actually
        a bit faster (and makes up for the allocation of extra registers above).

        Next step toward supporting re-entrant evaluation: Moved register file
        maintenance code into a proper "RegisterFile" class.
        
        There's a subtle change to the register file's internal layout: for
        global code / the global object, registerOffset is always 0 now. In
        other words, all register counting starts at 0, not 0 + (number of
        global variables). The helps simplify accounting when the number of
        global variables changes.

        Initial support for exceptions in SquirrelFish, only supports finalisers in the

        This doesn't add the required exception checks to existing code, it merely adds

        First step toward supporting re-entrant evaluation: Switch register
        clients from using "registers", a pointer to a register vector, to
        "registerBase", an indirect pointer to the logical first entry in the
        register file. (The logical first entry is the first entry that is not
        a global variable).
        
        With a vector, offsets into the register file remain good when the
        underlying buffer reallocates, but they go bad when the logical
        first entry moves. (The logical first entry moves when new global
        variables get added to the beginning of the register file.) With an
        indirect pointer to the logical first entry, offsets will remain good
        regardless.

        1.4% speedup on sunspider --squirrelfish. I suspect this is due to
        reduced allocation when creating closures, and reduced indirection
        through the register vector.

        * wtf/Vector.h: Added an accessor for an indirect pointer to the vector's
        buffer, which we currently use (incorrectly) for registerBase. This is
        temporary scaffolding to allow us to change client code without
        changing behavior.

        Support for evaluating multiple scripts in the same global environment.
        (Still don't support re-entrant evaluation yet.)

        The main changes here are:

        (1) Obey the ECMA 10.1.3 rules regarding how to resolve collisions when
        a given symbol is declared more than once. (This patch fixes the same
        issue for function code, too.)
        
        (2) In the case of var and/or function collisions, reuse the existing
        storage slot. For global code, this is required for previously
        generated instructions to continue to work. For function code, it's
        more of a "nice to have": it makes register layout in the case of
        collisions easier to understand, and has the added benefit of saving
        memory.
        
        (3) Allocate slots in the CodeGenerator's m_locals vector in parallel
        to register indexes in the symbol table. This ensures that, given an
        index in the symbol table, we can find the corresponding RegisterID
        without hashing, which speeds up codegen. 
        
        I moved responsibility for emitting var and function initialization
        instructions into the CodeGenerator, because bookkeeping in cases where
        var, function, and/or parameter names collide requires a lot of
        internal knowledge about the CodeGenerator.

        * VM/CodeGenerator.cpp:
        (KJS::CodeGenerator::addVar): Removed responsibility for checking whether
        a var declaration overwrites "arguments", because the check is
        inappropriate for global code, which may not have a pre-existing
        "arguments" symbol in scope. Also changed this function to return a
        boolean indicating whether addVar actually created a new RegisterID,
        or just reused an old one.
        
        (KJS::CodeGenerator::CodeGenerator): Split out the constructors for
        function code and global code, since they're quite different now.
        
        (KJS::CodeGenerator::registerForLocal): This function does its job
        without any hashing now.
        
        * VM/Machine.cpp: Move old globals and update "r" before executing a
        new script. That way, old globals stay at a constant offset from "r",
        and previously optimized code still works.
        
        * VM/RegisterID.h: Added the ability to allocate a RegisterID before
        initializing its index field. We use this for parameters now.

        * kjs/JSVariableObject.h:

        Implemented native function calls. (Re-entering from native code back
        to JS doesn't work yet, though.)

        0.2% speedup overall, due to some inlining tweaks. 3.6% regression on
        function-empty.js, since we're making a new virtual call and taking a
        new branch inside every op_call.
        
        I adjusted the JavaScriptCore calling convention to minimize overhead,
        like so:
        
        The machine calls a single virtual function, "getCallData", to get all
        the data it needs for a function call. Native code still uses the old
        "isObject()" check followed by an "implementsCall()" check, which
        aliases to "getCallData". (We can optimize native code to use getCallData
        at our leisure.)
        
        To supply a list of arguments, the machine calls a new List constructor
        that just takes a pointer and a length, without copying. Native code
        still appends to the list one argument at a time. (We can optimize
        native code to use the new List constructor at our leisure.)

        * VM/Machine.cpp:
        (KJS::Machine::privateExecute): Changed resize() call to grow() call,
        to encourage the compiler to inline the Vector code.

        * kjs/CallData.h: Added.
        (KJS::): CallData is a union because eventually native calls will stuff
        a function pointer into it, to eliminate the callAsFunction virtual call.

        * kjs/function.cpp:
        (KJS::FunctionImp::callAsFunction): Changed this to an ASSERT since
        it's not implemented yet.
        
        * kjs/list.h: Made the List class two-faced, to support the old way and
        the new way during this transition phase: lists can be made read-only
        with just a pointer and a legnth, or you can append to them one item
        at a time.

        * kjs/value.h:
        (KJS::jsUndefined): Marked this function ALWAYS_INLINE for the benefit
        of a certain compiler that doesn't know what's best for it.

        Change the Profiler to allow multiple profiles to be running at
        the same time. This can happen when you have nested console.profile()
        calls. This required two changes. First, the Profiler needed to keep a
        Vector of current profiles, instead of one. Second, a Profile needs
        to keep track of the global ExecState it started in and the page group
        identifier it is tracking.

        The stopProfiling call now takes the same arguments as startProfiling.
        This makes sure the correct profile is stopped. Passing a null UString
        as the title will stop the last profile for the matching ExecState.

        - We cache these values when we end profiling because otherwise we won't

        profiles that are in the allProfiles() list and a profile is only added

        Unicode format characters (Cf) should be removed from JavaScript source

        Of all Cf characters, we are only removing BOM, because this is what Firefox trunk has
        settled upon, after extensive discussion and investigation.

        Based on Darin's work on this bug.

        Test: fast/js/removing-Cf-characters.html

        * kjs/lexer.cpp:
        (KJS::Lexer::setCode): Tweak formatting. Use a call to shift(4) to read in the
        first characters, instead of having special case code here.
        (KJS::Lexer::shift): Add a loop when reading a character to skip BOM characters.

        <rdar://problem/4859666> WebKit needs availability macros in order to deprecate APIs

        Create WebKit availability macros that key off the Mac OS X version being targeted to
        determine the WebKit version being targeted.  Applications can define
        WEBKIT_VERSION_MIN_REQUIRED before including WebKit headers in order to target a specific
        version of WebKit.

        The availability header is being added to JavaScriptCore rather than WebKit as JavaScriptCore
        is the lowest-level portion of the public WebKit API.

        (replaced "new T" with "new T()").

        (KJS::Heap::heap): Added a method to find which heap a JSValue is allocated in.

        * kjs/collector.cpp: Changed "const size_t" constants to #defines, to avoid a PIC branch
        (gcc was using one to access a constant used in std::max(), because it takes a reference,
        even though std::max() itself was inlined).

        (KJS::Heap::Heap): Zero-initialize the heap.
        (KJS::allocateBlock): Added NEVER_INLINE, because this function uses a PIC branch, so
        inlining it in Heap::heapAllocate() is bad for performance, now that the latter doesn't

        (KJS::Heap::heapAllocate): Initialize Block::heap.

        - fix <rdar://problem/5657459> REGRESSION: JavaScriptCore no longer builds with
          GCC 4.2 due to pointer aliasing warnings

        Fix this by removing the HashTable optimizations that allowed us to share a back end
        implementation between hash tables with integers, pointers, RefPtr, and String objects
        as keys. The way it worked was incompatible with strict aliasing.

        This increases code size. On Mac OS X we'll have to regenerate .order files to avoid
        slowing down Safari startup times.

        This creates a slight slowdown in SunSpider, mitigated by the following four speedups:

        - speed up array put slightly by moving a branch (was already done for get)

        - speed up symbol table access by adding a function named inlineGet to HashMap
          and using that in symbolTableGet/Put

        - speed up PropertyNameArray creation by reducing the amount of reference count
          churn and uniqueness checking when adding names and not doing any allocation at
          all when building small arrays

        - speed up conversion of strings to floating point numbers by eliminating the
          malloc/free of the buffer for the ASCII copy of the string; a way to make
          things even faster would be to change strtod to take a UTF-16 string

        Note that there is considerable unused complexity now in HashSet/Map/Table to support
        "storage types", which is no longer used. Will do in a separate patch.

        * API/JSCallbackObjectFunctions.h:
        (KJS::JSCallbackObject<Base>::getPropertyNames): Removed explicit cast to Identifier to
        take advantage of the new PropertyNameArray::add overload and avoid reference count churn.
        * API/JSObjectRef.cpp:
        (JSPropertyNameAccumulatorAddName): Ditto.
        * JavaScriptCore.exp: Updated PropertyNameArray::add entry point name.

        * kjs/JSVariableObject.cpp: Removed now-unneeded IdentifierRepHashTraits::nullRepPtr
        definition (see below).
        (KJS::JSVariableObject::getPropertyNames): Removed explicit cast to Identifier.

        * kjs/JSVariableObject.h:
        (KJS::JSVariableObject::symbolTableGet): Use inlineGet for speed. Also changed to do
        early exit instead of nesting the body inside an if.
        (KJS::JSVariableObject::symbolTablePut): Ditto.

        * kjs/PropertyNameArray.cpp:
        (KJS::PropertyNameArray::add): Changed implementation to take a raw pointer instead of
        a reference to an identifier. Do uniqueness checking by searching the vector when the
        vector is short, only building the set once the vector is large enough.

        * kjs/PropertyNameArray.h: Added an overload of add for a raw pointer, and made the old
        add function call that one. Added an addKnownUnique function for use when the new
        name is known to be different from any other in the array. Changed the vector to have
        an inline capacity of 20.

        * kjs/SymbolTable.h: Changed IdentifierRepHash to inherit from the default hash for
        a RefPtr so we don't have to define so much. Added an overload of the hash function for
        a raw pointer as required by the new RefPtrHashMap. Got rid of the now-unneeded
        IdentifierRepHashTraits -- the default traits now work fine. Added a definition of
        empthValueIsZero to SymbolTableIndexHashTraits; not having it was incorrect, but harmless.

        * kjs/array_instance.cpp:
        (KJS::ArrayInstance::put): Move the maxArrayIndex check inside the branch that checks
        the index against the length, as done in the get function.

        (KJS::globalFuncKJSPrint): Changed to use the new getCString instead of cstring.

        * kjs/internal.cpp: Removed printInfo debugging function, a client of cstring.

        (KJS::JSObject::getPropertyNames): Removed explicit cast to Identifier.
        * kjs/property_map.cpp:
        (KJS::PropertyMap::getEnumerablePropertyNames): Ditto. Also added a special case for
        the case where the propertyNames array is empty -- in that case we know we're adding
        a set of names that are non-overlapping so we can use addKnownUnique.
        * kjs/ustring.cpp:
        (KJS::UString::getCString): Replaces cstring. Puts the C string into a CStringBuffer,
        which is a char Vector with an inline capacity. Also returns a boolean to indicate if
        the converion was lossy, which eliminates the need for a separate is8Bit call.
        (KJS::UString::toDouble): Changed to call getCString instead of cstring.
        * kjs/ustring.h: Ditto.

        * wtf/HashFunctions.h: Overload the hash and equal functions for RefPtr's default
        hash to take raw pointers. This works with the changes to RefPtrHashMap to avoid
        introducing refcount churn.

        * wtf/HashMap.h: Removed special code to convert the deleted value to the empty value
        when writing a new value into the map. This is now handled elsewhere.
        (WTF::HashMap::get): Removed code that checks for an empty hash table before calling
        HashTable::lookup; it's slightly more efficient to do this check inside lookup.

        * wtf/HashTable.h:
        (WTF::HashTable::isDeletedBucket): Changed to use isDeletedValue instead of using
        deletedValue and the equality operator.
        (WTF::HashTable::deleteBucket): Changed to use constructDeletedValue instead of
        using deletedValue and the assignment operator.
        (WTF::HashTable::checkKey): Added. Factors out the check for values that are empty
        or deleted keys that's used in various functions below.
        (WTF::HashTable::lookup): Changed to use checkKey, check for a 0 table, and also
        made public for use by RefPtrHashMap.
        (WTF::HashTable::lookupForWriting): Changed to use checkKey.
        (WTF::HashTable::fullLookupForWriting): Changed to use checkKey.
        (WTF::HashTable::add): Changed to use checkKey, and call initializeBucket on a
        deleted bucket before putting a new entry into it.
        (WTF::HashTable::addPassingHashCode): Ditto.
        (WTF::HashTable::deallocateTable): Check isDeletedBucket before calling ~ValueType.

        * wtf/HashTraits.h: Got ridd of all the HashTraits specialization for the integer
        types, since GeneicHashTraitsBase already deals with integers separately. Put the
        deleted value support into GenericHashTraitsBase. Changed FloatHashTraits to
        inherit from GenericHashTraits, and define construct/isDeletedValue rather than
        deletedValue. Removed the ref and deref functions from RefPtr's HashTraits, and
        defined construct/isDeletedValue. Eliminated DeletedValueAssigner. Changed
        PairHashTraits to define construct/isDeletedValue, and also merged
        PairBaseHashTraits in with PairHashTraits. Got rid of all specialization of
        HashKeyStorageTraits. We'll remove that, and the needsRef data member, later.

        * wtf/RefPtr.h: Added HashTableDeletedValueType, an enum type with a single value,
        HashTableDeletedValue. Used that type to make a new constructor to construct
        deleted values and also added an isHashTableDeletedValue function.

        * wtf/RefPtrHashMap.h: Added RefPtrHashMapRawKeyTranslator and used it to implement
        the raw pointer functions. This is a way to continue to avoid refcount thrash. We
        can't use the old way because it depended on the underlying map using a non-RefPtr
        type.
        (WTF::HashMap::find): Use find with RefPtrHashMapRawKeyTranslator.
        (WTF::HashMap::contains): Use contains with RefPtrHashMapRawKeyTranslator.
        (WTF::HashMap::inlineAdd): Use add with RefPtrHashMapRawKeyTranslator.
        (WTF::HashMap::get): Removed code that checks for an empty hash table before calling
        HashTable::lookup; it's slightly more efficient to do this check inside lookup.
        (WTF::HashMap::inlineGet): Added. Just like get, but marked inline for use in the
        symbol table code.

        Fix leaks during plugin tests (which actually excercise background JS), and potential
        PAC brokenness that was not reported, but very likely.

        The leaks shadowed a bigger problem with Identifier destruction. Identifier::remove involves
        an IdentifierTable lookup, which is now a per-thread instance. Since garbage collection can
        currently happen on a different thread than allocation, a wrong table was used.

        Bug 18367: Crash during celtic kane js speed 2007 test

        GCC 4.2 on x86_64 Linux decided to reorder the local variables in markCurrentThreadConservatively's
        stack frame.  This lead to the range of addresses the collector treated as stack to exclude the
        contents of volatile registers that markCurrentThreadConservatively forces onto the stack.  This was
        leading to objects being prematurely collected if the only reference to them was via a register at
        the time a collection occurred.

        The fix for this is to move the calculation of the top of the stack into a NEVER_INLINE function
        that is called from markCurrentThreadConservatively.  This forces the dummy variable we use for
        determining the top of stack to be in a different stack frame which prevents the compiler from
        reordering it relative to the registers that markCurrentThreadConservatively forces onto the stack.

        Fix for leak introduced by inline ScopeChainNode use

        To avoid any extra branches when managing an inline ScopeChainNode
        in the ScopeChain the inline node gets inserted with a refcount of
        2.  This meant than when the ScopeChain was destroyed the ScopeChainNodes
        above the inline node would be leaked.

        We resolve this by manually popping the inline node in the
        FunctionExecState destructor.

        Fixed <rdar://problem/5689093> Stricter (ES4) eval semantics
        
        The basic rule is:
        
        - "eval(s)" is treated as an operator that gives the ES3 eval behavior.
            ... but only if there is no overriding declaration of "eval" in scope.
        - All other invocations treat eval as a function that evaluates a
        script in the context of its "this" object.
            ... but if its "this" object is not the global object it was
            originally associated with, eval throws an exception.
        
        Because only expressions of the form "eval(s)" have access to local
        scope, the compiler can now statically determine whether a function
        needs local scope to be dynamic.

        * kjs/nodes.h: Added FunctionCallEvalNode. It works just like
        FuncationCallResolveNode, except it statically indicates that the node
        may execute eval in the ES3 way.

        we only support calling eval on the global object.

        Fix for <rdar://problem/5778247> - Reproducible crash on storage/execute-sql-args.html

        DatabaseThread::unscheduleDatabaseTasks() manually filters through a MessageQueue,
        removing particular items for Databases that were shutting down.

        This filtering operation is not atomic, and therefore causes a race condition with the
        MessageQueue waking up and reading from the message queue.  

        The end result was an attempt to dereference a null DatabaseTask.  Timing-wise, this never
        seemed to happen in a debug build, otherwise an assertion would've caught it.  Replacing that
        assertion with a crash in a release build is what revealed this bug.

        Partial fix for <rdar://problem/5744037> Gmail out of memory (17455)
        
        I'm removing KJS_MEM_LIMIT for the following reasons:
        
        - We have a few reports of KJS_MEM_LIMIT breaking important web
        applications, like GMail and Google Reader. (For example, if you
        simply open 12 GMail tabs, tab #12 will hit the limit.)

        - Firefox has no discernable JS object count limit, so any limit, even
        a large one, is a potential compatibility problem.
        
        - KJS_MEM_LIMIT does not protect against malicious memory allocation,
        since there are many ways to maliciously allocate memory without
        increasing the JS object count.
        
        - KJS_MEM_LIMIT is already mostly broken, since it only aborts the
        script that breaches the limit, not any subsequent scripts.
        
        - We've never gotten bug reports about websites that would have
        benefited from an unbroken KJS_MEM_LIMIT. The initial check-in of
        KJS_MEM_LIMIT (KJS revision 80061) doesn't mention a website that
        needed it.
        
        - Any website that brings you anywhere close to crashing due to the
        number of live JS objects will almost certainly put up the "slow
        script" dialog at least 20 times beforehand.

        slower due to r28884 (global variable symbol table optimization)

        Geoff's theory is that the slowdown was due to copying hash tables when
        putting things into the back/forward cache. If that's true, then this
        should fix the problem.

        (According to Geoff's measurements, in a PLT that exaggerates the
        importance of symbol table saving during cached page creation, this
        patch is a ~3X speedup in cached page creation, and a 9% speedup overall.)

        * JavaScriptCore.exp: Updated.

        * kjs/JSVariableObject.cpp:
        (KJS::JSVariableObject::saveLocalStorage): Updated for changes to SavedProperty,
        which has been revised to avoid initializing each SavedProperty twice when building
        the array. Store the property names too, so we don't have to store the symbol table
        separately. Do this by iterating the symbol table instead of the local storage vector.
        (KJS::JSVariableObject::restoreLocalStorage): Ditto. Restore the symbol table as
        well as the local storage vector.

        * kjs/JSVariableObject.h: Removed save/restoreSymbolTable and do that work inside
        save/restoreLocalStorage instead. Made restoreLocalStorage a non-const member function

        (KJS::PropertyMap::save): Updated for data member name change and to use the new

        (KJS::PropertyMap::restore): Updated for SavedProperty changes.

        * kjs/property_map.h: Changed SavedProperty from a struct to a class. Set it up so
        it does not get initialized at construction time to avoid initializing twice when

          Incorrect Function.toString behaviour with read/modify/write operators performed on negative numbers

        Test: fast/js/function-toString-parentheses.html

        The problem here was that a NumberNode with a negative number in it had the wrong
        precedence. It's not a primary expression, it's a unary operator with a primary
        expression after it.

        Once the precedence of NumberNode was fixed, the cases from bug 17020 were also
        fixed without trying to treat bracket nodes like dot nodes. That wasn't needed.
        The reason we handle numbers before dot nodes specially is that the dot is a
        legal character in a number. The same is not true of a bracket. Eventually we
        could get smarter, and only add the parentheses when there is actual ambiguity.
        There is none if the string form of the number already has a dot in it, or if
        it's a number with a alphabetic name like infinity or NAN.

        If both XP_MACOSX and XP_UNIX are defined then X11.h and Carbon.h will both be included.
        These provide conflicting definitions for a type named 'Cursor'.  As XP_UNIX is set by

        Reworked the JavaScriptCore Qt bindings:
        
        * Add initial support for string and variant arrays, as well
        as sub QObjects in the JS bindings.
        
        * Don't expose fields marked as not scriptable by moc.
        
        * Add support for dynamic properties and accessing named
        QObject children of an object (like QtScript and older
        IE DOM style JS).
        * Add support for custom toString methods.
        
        * Fine tune some bindings to be closer to QtScript.
        Make void functions return undefined, and empty/
        null QStrings return a zero length string.
        
        * Create framework for allowing more direct method calls.
        Since RuntimeMethod doesn't allow us to add additional
        methods/properties to a function, add these classes.
        Start prototyping object.signal.connect(...).
        
        * Add signal support to the Qt bindings.
        Allow connecting to signals (object.signal.connect(slot)),
        disconnecting, and emitting signals.  Currently chooses
        the first signal that matches the name, so this will need
        improvement.
        
        * Add property names, and resolve signals closer to use.
        Enumerating properties now returns some of the Qt properties
        and signals.  Slots and methods aren't quite present.  Also,
        resolve signal connections etc. closer to the time of use, so
        we can do more dynamic resolution based on argument type etc.
        Still picks the first one with the same name, at the moment.
        
        * Make signature comparison code consistent.
        Use the same code for checking meta signatures in
        the method and fallback getters, and avoid a
        QByteArray construction when we can.
        
        * Fix minor memory leak, and handle pointers better.
        Delete the private object in the dtors, and use RefPtrs
        for holding Instances etc.
        
        * Handle method lookup better.
        Allow invocation time method lookup based on the arguments,
        which is closer to QtScript behaviour.  Also, cache the
        method lists and delete them in the QtClass dtor (stops
        a memory leak).
        
        * Improve JS to Qt data type conversions.
        Add some support for Date & RegExp JS objects,

        conversion.

        Fix <rdar://problem/5595552> r27608 introduced a 20% increase in JS binary size, 4% increase in WebCore binary size

        - This changes the way JS functions that use Lookup tables are handled.  Instead of using
          one class per function, which allowed specialization of the virtual callAsFunction
          method, we now use one class, PrototypeFunction, which takes a pointer to a static
          function to use as the implementation.  This significantly decreases the binary size
          of JavaScriptCore (about 145k on an Intel only build) while still keeping some of the
          speedup r27608 garnered (SunSpider says this is 1.005x as slow, which should leave some
          wiggle room from the original 1% speedup) and keeps the functions implementations in separate
          functions to help with optimizations.

        Add binding language type to Instance.
        Allows runtime determination of the type of an
        Instance, to allow safe casting.  Doesn't actually
        add any safe casting yet, though.

        Add a helper function to get an Instance from a JSObject*.
        Given an object and the expected binding language, see if
        the JSObject actually wraps an Instance of the given type
        and return it.  Otherwise return 0.

        Move RuntimeObjectImp creations into Instance.
        Make the ctor protected, and Instance a friend class, so
        that all creation of RuntimeObjectImps goes through
        one place.

        Remove copy ctor/assignment operator for QtInstance.
        Instance itself is Noncopyable, so QtInstance doesn't
        need to have these.

        Add caching for QtInstance and associated RuntimeObjectImps.
        Push any dealings with QtLanguage bindings into QtInstance,
        and cache them there, rather than in the Instance layer.  Add
        a QtRuntimeObjectImp to help with caching.

        variable access (16644)
        
        This bug was caused by var declarations shadowing built-in properties of
        the global object.
        
        To match Firefox, we've decided that var declarations will never shadow
        built-in properties of the global object or its prototypes. We used to
        behave more like IE, which allows shadowing, but walking that line got
        us into trouble with websites that sent us down the Firefox codepath.

        * kjs/fpconst.cpp: Move the contents of this file from here back to
        value.cpp. The reason this was in a separate file is that the DARWIN
        version of this used a declaration of the globals with a different
        type to avoid creating "init routines". That's no longer necessary for
        DARWIN and was never necessary for the non-DARWIN code path.
        To make this patch easy to merge, I didn't actually delete this file
        yet. We'll do that in a separate changeset.

        * kjs/value.cpp: If C99's NAN and INFINITY are present, then use them,
        othrewise use the union trick from fpconst.cpp. I think it would be
        better to eliminate KJS::NaN and KJS::Inf and just use NAN and INFINITY
        directly or std::numeric_limits<double>::quiet_nan() and
        std::numeric_limits<double>::infinity(). But when I tried that, it

        Also included one other speed-up -- remove the call to reserveCapacity from
        FunctionBodyNode::processDeclarations in all but the most unusual cases.

        Restored the stack which prevents infinite loops for brackets that match the empty
        string; it had been removed as an optimization.

        Unfortunately, restoring this stack causes the regular expression test in SunSpider
        to be 1.095x as slow and the overall test to be 1.004x as slow. Maybe we can find
        a correct optimization to restore the speed!

        It's possible the original change was on the right track but just off by one.

          speed up function calls by making ScopeChain::push cheaper

        This gives a 1.019x speedup on SunSpider.

        After doing this, I realized this probably will be obsolete when the optimization
        to avoid creating an activation object is done. When we do that one we should check
        if rolling this out will speed things up, since this does add overhead at the time
        you copy the scope chain.

        * kjs/object.h: Removed the ScopeChain::release function. It was
        marked inline, and called in exactly one place, so moved it there.
        No idea why it was in this header file!

        * kjs/scope_chain.cpp: Removed the overload of the ScopeChain::push
        function that takes another ScopeChain. It was unused. I think we used
        it over in WebCore at one point, but not any more.

        * kjs/scope_chain.h: Changed ScopeChainNode into a struct rather than
        a class, got rid of its constructor so we can have one that's uninitialized,
        and moved the refCount into a derived struct, ScopeChainHeapNode. Made _node
        mutable so it can be changed in the moveToHeap function. Changed the copy
        constructor and assignment operator to call moveToHeap, since the top node
        can't be shared when it's embedded in another ScopeChain object. Updated
        functions as needed to handle the case where the first object isn't on the
        heap or to add casts for cases where it's guaranteed to be. Changed the push
        function to always put the new node into the ScopeChain object; it will get
        put onto the heap when needed later.

        - Assignment expressions get properly optimized for local variables

        - Most of the old VarStatement/VarDecl logic is now only used for const declarations,

        AST optimization: Avoid NULL-checking ForNode's child nodes.
        
        0.6% speedup on SunSpider.
        
        This is a proof of concept patch that demonstrates how to optimize
        grammar productions with optional components, like
        
            for (optional; optional; optional) {
                ...
            }
            
        The parser emits NULL for an optional component that is not present.

        Instead of checking for a NULL child at execution time, a node that
        expects an optional component to be present more often than not checks
        for a NULL child at construction time, and substitutes a viable
        alternative node in its place.

        (We'd like the parser to start emitting NULL a lot more once we teach
        it to emit NULL for certain no-op productions like EmptyStatement and
        VariableStatement, so, as a foundation, it's important for nodes with
        NULL optional components to be fast.)

        REGRESSION: 303-304: Embedded YouTube video fails to render- JS errors (16150) (Flash 9)
        
        Get rid of unnecessary and incorrect security checks for plug-ins accessing JavaScript objects. 
        
        The way this used to work was that each NPObject that wrapped a JSObject would have a root object
        corresponding to the frame object (used for managing the lifecycle) and an origin root object (used for
        doing security checks). 
        
        This would prevent a plug-in from accessing a frame's window object if it's security origin was different
        (some parts of the window, such as the location object, can be accessed from frames with different security 
        origins, and those checks are being done in WebCore).
        
        Also, if a plug-in were to access a window object of a frame that later went away, it could lead to that
        Window JSObject being garbage collected and the NPObject pointing to freed memory.
        
        How this works now is that there is no origin root object anymore, and all NPObject wrappers that are created
        for a plug-in will have the root object of the containing frame of that plug-in.

        Merged different implementations of Parser::parse into a single,
        templatized implementation, in preparation for adding yet another
        implementation for "eval" code.
        
        JS and layout tests pass.

        * pcre/pcre_compile.cpp: Changed some names to use interCaps intead of under_scores.
        (branchIsAnchored): Broke is_anchored into two separate functions; this one works on a
        branch and the other on an anchor. The old function would only work on a bracket.
        Also removed unneeded parameters; the anchored check does not require the bracket
        map or the options any more because we have a reduced set of features.
        (bracketIsAnchored): Ditto.
        (branchNeedsLineStart): Broke canApplyFirstCharOptimization into two functions and gave
        both a better name. This is the function that was returning the wrong value. The failure
        was beacuse the old function would only work on a bracket.
        (bracketNeedsLineStart): Ditto.
        (jsRegExpCompile): Changed to call the appropriate branch or bracket flavor of the
        functions based on whether we compiled an outer bracket. Also removed inaccurate comments
        and unneeded parameters.

        * kjs/Parser.h: Added sourceURL(), m_sourceURL, and m_lastLine. Added a lastLine

        1. Created distinct parser calls for parsing function bodies vs
        programs. This will help later with optimizing global variable access.
        
        2. Turned Parser into a singleton. Cleaned up Lexer's singleton 
        interface.
        
        3. Modified Lexer to free a little more memory when done lexing. (Added
        FIXMEs for similar issues that I didn't fix.)
        
        4. Changed Lexer::makeIdentifier and Lexer::makeUString to start 
        respecting the arguments passed to them. (No behavior change, but this
        problem could have caused serious problems for an unsuspecting user of
        these functions.)
        
        5. Removed KJS_DEBUG_MEM because it was bit-rotted.

        Cleaned up the JavaScript grammar a bit.
        
        1. Changed BlockNode to always hold a child vector (which may be empty),
        eliminating a few NULL-check branches in the common execution case.
        
        2. Changed the Block production to correctly report its starting and 
        ending line numbers to the debugger. (It used to report its ending line
        as its starting line.) Also, removed duplicate line-reporting code
        inside the BlockNode constructor.
        
        3. Moved curly braces up from FunctionBody production into parent
        productions. (I had to move the line number reporting code, too, since
        it depends on the location of the curly braces.) This matches the ECMA
        spec more closely, and makes some future changes I plan easier.

        - fix http://bugs.webkit.org/show_bug.cgi?id=11231
          RegExp bug when handling newline characters
          and a number of other differences between PCRE behvior
          and JavaScript regular expressions:

          + single-digit sequences like \4 should be treated as octal
            character constants, unless there is a sufficient number
            of brackets for them to be treated as backreferences

          + \8 turns into the character "8", not a binary zero character
            followed by "8" (same for 9)

          + only the first 3 digits should be considered part of an
            octal character constant (the old behavior was to decode
            an arbitrarily long sequence and then mask with 0xFF)

          + if \x is followed by anything other than two valid hex digits,
            then it should simply be treated a the letter "x"; that includes
            not supporting the \x{41} syntax

          + if \u is followed by anything less than four valid hex digits,
            then it should simply be treated a the letter "u"

          + an extra "+" should be a syntax error, rather than being treated
            as the "possessive quantifier"

          + if a "]" character appears immediately after a "[" character that
            starts a character class, then that's an empty character class,
            rather than being the start of a character class that includes a
            "]" character

          + a "$" should not match a terminating newline; we could have gotten
            PCRE to handle this the way we wanted by passing an appropriate option

        Test: fast/js/regexp-no-extensions.html

        * pcre/pcre_compile.cpp:
        (check_escape): Check backreferences against bracount to catch both
        overflows and things that should be treated as octal. Rewrite octal
        loop to not go on indefinitely. Rewrite both hex loops to match and
        remove \x{} support.
        (compile_branch): Restructure loops so that we don't special-case a "]"
        at the beginning of a character class. Remove code that treated "+" as
        the possessive quantifier.
        (jsRegExpCompile): Change the "]" handling here too.

        * pcre/pcre_exec.cpp: (match): Changed CIRC to match the DOLL implementation.
        Changed DOLL to remove handling of "terminating newline", a Perl concept
        which we don't need.

        * tests/mozilla/expected.html: Two tests are fixed now:
        ecma_3/RegExp/regress-100199.js and ecma_3/RegExp/regress-188206.js.
        One test fails now: ecma_3/RegExp/perlstress-002.js -- our success before
        was due to a bug (we treated all 1-character numeric escapes as backreferences).
        The date tests also now both expect success -- whatever was making them fail
        before was probably due to the time being close to a DST shift; maybe we need
        to get rid of those tests.

        Fix <rdar://5578982> ASSERT in HashTable::checkTableConsistencyExceptSize beneath WebNotificationCenter

        The bug was due to a mismatch between HashMap::remove and
        HashTable::checkTableConsistency. HashMap::remove can delete the value
        stored in the HashTable (by derefing it), which is not normally
        allowed by HashTable. It's OK in this case because the value is about
        to be removed from the table, but HashTable wasn't aware of this.

        HashMap::remove now performs the consistency check itself before
        derefing the value.

        Darin noticed that the same bug would occur in HashSet, so I've fixed
        it there as well.

          next round of changes to JSRegExp (formerly PCRE)

        This is a combination of converting to C++, tweaking the API, and adding
        some additional optimizations.

        Future steps will involve getting rid of the use of UTF-8 completely
        (we'll use UTF-16 exclusively instead), eliminating more source files,
        and some more speed-ups.

        SunSpider says the current round is an 0.9% speed-up overall, and a
        5.3% speed-up for regexp.

        * JavaScriptCore.pri:
        * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.vcproj:
        * JavaScriptCore.vcproj/dftables/dftables.vcproj:

        * JavaScriptCoreSources.bkl:
        * jscore.bkl:
        Updated for new source file names and ForwardingHeaders.

        * kjs/regexp.cpp:
        (KJS::RegExp::RegExp): Changed to use the error message without calling
        strdup on it and to pass the new types and options.
        (KJS::RegExp::~RegExp): Removed the now-unneeded free of the error message.
        (KJS::RegExp::match): Pass the new types and options.
        * kjs/regexp.h: Update type of m_constructionError.

        * pcre/AUTHORS: Update to reflect the status of the project -- we don't include
        the Google parts, and this isn't the PCRE library, per se.
        * pcre/COPYING: Ditto.

        * pcre/dftables.cpp: Copied from JavaScriptCore/pcre/dftables.c.
        (main): Removed unneeded ctype_digit.

        * pcre/pcre.h: Convert to C++, tweak API a bit. Use UChar instead of JSRegExpChar.

        * pcre/pcre_compile.cpp: Copied from JavaScriptCore/pcre/pcre_compile.c.
        Moved a lot of private stuff used only within this file here from pcre_internal.h.
        Renumbered the error codes.
        (error_text): Use a single string with embedded nulls for the error text (I got
        this idea from newer versions of PCRE).
        (check_escape): Changed return type to be enum instead of int. Replaced ctype_digit
        uses with isASCIIDigit.
        (is_counted_repeat): Ditto.
        (read_repeat_counts): Ditto.
        (first_significant_code): Ditto.
        (find_fixedlength): Ditto.
        (could_be_empty_branch): Ditto.
        (compile_branch): Ditto. Also removed some code that handles changing options.
        JavaScript doesn't have any of the features that allow options to change.
        (compile_regex): Updated for change to options parameter.
        (is_anchored): Ditto.
        (find_firstassertedchar): Ditto.
        (jsRegExpCompile): Changed to take separate flags instead of an options int.
        Also changed to call new/delete instead of pcre_malloc/free.
        (jsRegExpFree): Ditto.

        * pcre/pcre_exec.cpp: Copied from JavaScriptCore/pcre/pcre_exec.c.
        Added a case that uses computed goto for the opcode loop, but did not turn it on.
        Changed the RMATCH macro to handle returns more efficiently by putting the where
        pointer in the new frame instead of the old one, allowing us to branch to the
        return with a single statement. Switched to new/delete from pcre_malloc/free.
        Changed many RRETURN callers to not set the return value since it's already
        set correctly. Replaced the rrc variable with an is_match variable. Values other
        than "match" and "no match" are now handled differently. This allows us to remove
        the code to check for those cases in various rules.
        (match): All the case statements use a macro BEGIN_OPCODE instead. And all the
        continue statements, or break statements that break out of the outer case use
        a macro NEXT_OPCODE instead. Replaced a few if statements with assertions.
        (jsRegExpExecute): Use new/delete instead of pcre_malloc/free. Removed unused
        start_match field from the match block.

        * pcre/pcre_internal.h: Moved the last few configuration macros from pcre-config.h
        in here. Removed various unused types. Converted from JSRegExpChar to UChar.
        Eliminated pcre_malloc/free. Replaced the opcode enum with a macro that can be
        used in multiple places. Unfortunately we lose the comments for each opcode; we
        should find a place to put those back. Removed ctype_digit.

        * pcre/pcre_maketables.cpp: Copied from JavaScriptCore/pcre/pcre_maketables.c.
        (pcre_maketables): Got rid of the conditional code that allows this to be compiled
        in -- it's only used for dftables now (and soon may be obsolete entirely).
        Changed code for cbit_digit to not use isdigit, and took the "_" case out of the
        loop. Removed ctype_digit.

        * pcre/pcre_ord2utf8.cpp: Copied from JavaScriptCore/pcre/pcre_ord2utf8.c.

        * pcre/pcre_tables.cpp: Copied from JavaScriptCore/pcre/pcre_tables.c.
        Moved _pcre_OP_lengths out of here into pcre_exec.cpp.

        * pcre/pcre_ucp_searchfuncs.cpp: Copied from JavaScriptCore/pcre/pcre_ucp_searchfuncs.c.
        Updated for other file name changes.

        * pcre/pcre_xclass.cpp: Copied from JavaScriptCore/pcre/pcre_xclass.c.

        * pcre/ucpinternal.h: Updated header.

        * pcre/ucptable.cpp: Copied from JavaScriptCore/pcre/ucptable.c.

        * wtf/ASCIICType.h: (WTF::isASCIIDigit): Removed a branch by changing from && to
        & for this operation. Also added an overload that takes an int because that's
        useful for PCRE. Later we could optimize for int and overload other functions in
        this file; stuck to this simple one for now.

        * wtf/unicode/icu/UnicodeIcu.h: Removed unused isUpper.
        * wtf/unicode/qt4/UnicodeQt4.h: Ditto.

        * pcre/LICENCE: Removed.
        * pcre/pcre-config.h: Removed.
        * wtf/FastMallocPCRE.cpp: Removed.

        * pcre/dftables.c: Renamed to cpp.

          getting characters by indexing into a string is very slow

        This fixes one source of the slowness -- the conversion to an unused
        Identifier as we call the get function from the slot -- but doesn't
        fix others, such as the fact that we have to allocate a new UString::Rep
        for every single character.

        Speeds up string-base64 30%, and at least 0.5% overall.
        But does slow down access-fannkuch quite a bit. Might be worth
        revisiting in the future to see what we can do about that (although
        I did look at a profile for a while).

        * kjs/property_slot.h: Add a new marker for "numeric" property slots;

        Fix regression caused by earlier bitwise and optimisation.  1 & undefined != 1.

        The implementation of JSImmediate::areBothImmediateNumbers relies on 
        (JSImmediate::getTag(immediate1) & JSImmediate::getTag(immediate2)) having 
        a unique result when both immediate values are numbers.

        The regression was due to UndefinedType & NumberType returning NumberType (3 & 1).

        Add a fast path for bitwise-and of two immediate numbers for a 0.7% improvement in SunSpider (4% bitop improvement).

        This only improves bitwise-and performance, as the additional logic required 
        for similar code paths on or, xor, and shifting requires additional operations
        and branches that negate (and in certain cases, regress) any advantage we might
        otherwise receive.

        This improves performance on all bitop tests, the cryptography tests, as well as 
        the string-base64 and string-unpack-code tests.  No significant degradation on 
        any other tests.

        Convert JavaScript internal function objects to use one class per
        function.  This avoids a switch statement inside what used to be
        the shared function classes and will allow Shark to better analyze
        the code.

        To make this switch, the value property of the HashEntry was changed
        to a union of an intptr_t (which is used to continue handle valueGetters)
        and function pointer which points to a static constructor for the
        individual new function objects.

        SunSpider claims this is a 1.0% speedup.

        Replace the use of floats for immediate values with the use of integers for a 4.5% improvement in SunSpider.

        Unfortunately this change results in NaN, +Inf, -Inf, and -0 being heap allocated now, but
        we should now have faster array access, faster immediate to double conversion, and the 
        potential to further improve bitwise operators in future.

        This also removes the need for unions to avoid strict aliasing problems when extracting

          REGRESSION (r27387): Memory corruption when running fast/js/kde/delete.html

        There was a mistake in the algorithm used to find an empty slot in the property
        map entries vector; when we were putting in a new property value and not overwriting
        an existing deleted sentinel, we would enlarge the entries vector, but would not
        overwrite the stale data that's in the new part. It was easy to pin this down by
        turning on property map consistency checks -- I never would have landed with this
        bug if I had run the regression tests once with consistency checks on!

        * kjs/property_map.cpp: (KJS::PropertyMap::put): Changed logic for the case where
        foundDeletedElement is false to always use the item at the end of the entries vector.
        Also allowed me to merge with the logic for the "no deleted sentinels at all" case.

          remove unused PCRE features for speed

        A first step toward removing the PCRE features we don't use.
        This gives a 0.8% speedup on SunSpider, and a 6.5% speedup on
        the SunSpider regular expression test.

        Replaced the public interface with one that doesn't use the
        name PCRE. Removed code we don't need for JavaScript and various
        configurations we don't use. This is in preparation for still
        more changes in the future. We'll probably switch to C++ and
        make some even more significant changes to the regexp engine
        to get some additional speed.

        There's probably additional unused stuff that I haven't
        deleted yet.

        This does mean that our PCRE is now a fork, but I think that's
        not really a big deal.

        * JavaScriptCore.exp: Remove the 5 old entry points and add
        the 3 new entry points for WebCore's direct use of the regular
        expression engine.

        * kjs/config.h: Remove the USE(PCRE16) define. I decided to flip
        its sense and now there's a USE(POSIX_REGEX) instead, which should
        probably not be set by anyone. Maybe later we'll just get rid of it
        altogether.

        * kjs/regexp.h:
        * kjs/regexp.cpp:
        (KJS::RegExp::RegExp): Switch to new jsRegExp function names and
        defines. Cut down on the number of functions used.
        (KJS::RegExp::~RegExp): Ditto.
        (KJS::RegExp::match): Ditto.

        * pcre/dftables.c: (main): Get rid of ctype_letter and ctype_meta,
        which are unused.

        * pcre/pcre-config.h: Get rid of EBCIDIC, PCRE_DATA_SCOPE, const,
        size_t, HAVE_STRERROR, HAVE_MEMMOVE, HAVE_BCOPY, NEWLINE,
        POSIX_MALLOC_THRESHOLD, NO_RECURSE, SUPPORT_UCP, SUPPORT_UTF8,
        and JAVASCRIPT. These are all no longer configurable in our copy
        of the library.

        * pcre/pcre.h: Remove the macro-based kjs prefix hack, the PCRE
        version macros, PCRE_UTF16, the code to set up PCRE_DATA_SCOPE,
        the include of <stdlib.h>, and most of the constants and
        functions defined in this header. Changed the naming scheme to
        use a JSRegExp prefix rather than a pcre prefix. In the future,
        we'll probably change this to be a C++ header.

        * pcre/pcre_compile.c: Removed all unused code branches,
        including many whole functions and various byte codes.
        Kept changes outside of removal to a minimum.

        parameters around a bit.
        (jsRegExpFree): Added.

        * pcre/pcre_exec.c: Removed many unused opcodes and variables.
        Also started tearing down the NO_RECURSE mechanism since it's
        now the default. In some cases there were things in the explicit
        frame that could be turned into plain old local variables and
        other small like optimizations.
        (pchars):
        (match_ref):
        (match): Changed parameters quite a bit since it's now not used
        recursively.
        (jsRegExpExecute): Renamed from pcre_exec.

        * pcre/pcre_internal.h: Get rid of PCRE_DEFINITION, PCRE_SPTR,
        PCRE_IMS, PCRE_ICHANGED, PCRE_NOPARTIAL, PCRE_STUDY_MAPPED,
        PUBLIC_OPTIONS, PUBLIC_EXEC_OPTIONS, PUBLIC_DFA_EXEC_OPTIONS,
        PUBLIC_STUDY_OPTIONS, MAGIC_NUMBER, 16 of the opcodes,
        _pcre_utt, _pcre_utt_size, _pcre_try_flipped, _pcre_ucp_findprop,
        and _pcre_valid_utf8. Also moved pcre_malloc and pcre_free here.

        * pcre/pcre_maketables.c: Changed to only compile in dftables.
        Also got rid of many of the tables that we don't use.

        * pcre/pcre_tables.c: Removed the unused Unicode property tables.

        * wtf/FastMallocPCRE.cpp: Removed unused bits. It would be good
        to eliminate this completely, but we need the regular expression
        code to be C++ first.

        * pcre/ucp.h:

          change property map data structure for less memory use, better speed

        The property map now has an array of indices and a separate array of
        property map entries. This slightly slows down lookup because of a second
        memory acess, but makes property maps smaller and faster to iterate in
        functions like mark().

        SunSpider says this is 1.2% faster, although it makes the bitwise-end test
        more than 10% slower. To fix that we'll need to optimize global variable lookup.

        Much supporting work done by Maciej Stachowiak, Maks Orlovich, and 
        Cameron Zwarich.
        
        AST transfom to replace slow resolve nodes with fast local variable
        alternatives that do direct memory access. Currently, only ResolveNode
        provides a fast local variable alternative. 6 others are soon to come.
        
        16.7% speedup on SunSpider.
        
        Most of this patch is just scaffolding to support iterating all the 
        resolve nodes in the AST through optimizeResolveNodes(). In 
        optimizeResolveNodes(), most classes just push their child nodes onto 
        the processing stack, while ResolveNodes actually replace themselves in 
        the tree with more optimized alternatives, if possible.

        Here are the interesting bits:

        * kjs/nodes.h: Added PlacementNewAdoptTag, along with implementations 
        in Node and ResolveNode. This tag allows you to use placement new to 
        swap out a base class Node in favor of a subclass copy that holds the
        same data. (Without this tag, default initialization would NULL out
        RefPtrs, change line numbers, etc.)

        * kjs/nodes.cpp:
        (KJS::ResolveNode::evaluate): Since we're taking the slow path, ASSERT
        that the fast path is impossible, to make sure we didn't leave anything
        on the table.

          remove GroupNode to simplify AST and possibly get a modest speedup

        This patch removes 4 node types: GroupNode, PropertyNameNode,
        FunctionCallParenBracketNode, and FunctionCallParenDotNode.

        To remove GroupNode, we add knowledge of precedence to the tree nodes,
        and use that when serializing to determine where parentheses are needed.
        This means we no longer have to represent parentheses in the tree.

        The precedence values are named after productions in the grammar from the
        JavaScript standard.

        SunSpider says this is an 0.4% speedup.

        * kjs/function.h:
        * kjs/function.cpp: Removed escapeStringForPrettyPrinting -- it's part of
        serialization, so I moved it to the file that takes care of that.

        * kjs/grammar.y: Changed makeGetterOrSetterPropertyNode to use 0 to
        indicate failure instead of a separate boolean. Got rid of PropertyNameNode
        by merging the PropertyName rule into the Property rule (which was easier
        than figuring out how to pass the Identifier from one node to another).
        Got rid of GroupNode, nodeInsideAllParens(), FunctionCallParenBracketNode,
        and FunctionCallParenDotNode.

        * kjs/nodes.h: Removed unused forward declarations and Operator values.
        Added Precedence enum, and precedence function to all nodes. Removed
        nodeInsideAllParens. Added streamBinaryOperator function for serialization.
        Removed GroupNode and PropertyNameNode. Made PropertyNode store an Identifier.
        Removed FunctionCallParenBracketNode and FunctionCallParenDotNode.

        * kjs/nodes.cpp: Removed Node::nodinsideAllParens, GroupNode, and PropertyNameNode.
        (KJS::PropertyListNode::evaluate): Changed code to get name directly instead
        of converting it from an Identifier to a jsString then back to a UString
        then into an Identifier again!

        * kjs/nodes2string.cpp: Changed special-token implementation to use a separate
        function for each of Endl, Indent, Unindent, and DotExpr instead of using a
        single function with a switch. Added a precedence that you can stream in, to
        cause the next node serialized to add parentheses based on that precedence value.
        (KJS::operatorString): Moved to the top of the file.
        (KJS::escapeStringForPrettyPrinting): Moved here from function.cpp. Removed old
        workaround for snprintf, since StringExtras.h takes care of that.
        (KJS::operator<<): Made the char and char* versions faster by using UString's
        character append functions instead of constructing a UString. Added the logic
        to the Node* version to add parentheses if needed.

        - numerous HashTable performance improvements
        
        This does not quite add up to a measurable win on SunSpider, but it allows a
        follow-on > 3% improvement and probably helps WebCore too.
        
        I made the following improvements, among others:
        
        - Made HashFunctions note whether it is ok to compare a real value with the equal() function
        to the empty or deleted value, and used this to optimize the comparisons done in hash lookup.
        
        - Specialized lookup so it doesn't have to do so many extra branches and build so many extra
        std::pairs for cases that don't need them. There are now four versions, one for read-only access,
        two for writing, and one folded directly into add() (these all were improvments).
        
        - Made HashMap::get() use lookup() directly instead of find() to avoid having to build iterators.
        
        - Made a special constructor for iterators that knows it points to
        a valid filled cell and so skips updating itself.

        - Reordered memory accesses in the various lookup functions for better code generation
        
        - Made simple translators avoid passing a hash code around
        
        - Other minor tweaks

        This is in preparation for adding a symbol table to the activation

        The basic strategy here is to rely on the mutual exclusion between
        the arguments object pointer and the function pointer (you only need

        Change JavaScriptCore.vcproj to use DerivedSources.make

        We were trying to emulate the logic of make in
        build-generated-files.sh, but we got it wrong. We now use a
        build-generated-files very much like the one that WebCore uses to
        invoke make.

        We also now only have a Debug configuration of dftables which we build
        even when doing a Release build of JavaScriptCore. dftables also no
        longer has the "_debug" name suffix.

        This does not match Firefox, which waits to process a function
        declaration until the declaration's containing block executes, but it 
        does match IE and the ECMA spec. (10.1.3 states that var and function 
        declarations should be processed at the same time -- namely, "On 
        entering an execution context." 12.2 states that "A Block does not 
        define a new execution scope.")

        2. Declaration processing proceeds iteratively now, rather than 
        recursively, storing the nodes is finds in stacks. This will later 
        facilitate an optimization to hold on to the gathered declaration nodes, 
        rather than re-fetching them in every function call.

        Removed surprising self-named "hack" that made nested functions 
        available as named properties of their containing functions, and placed
        containing function objects in the scope chains of nested functions.
        
        There were a few reasons to remove this "hack:"

        1. It contradicted FF, IE, and the ECMA spec.

        2. It incurred a performance penalty, since merely parsing a function 
        required parsing its body for nested functions (and so on).

        3. SVN history contains no explanation for why it was added. It was just
        legacy code in a large merge a long, long time ago.

        1. Added shrink(), which is a version of resize() that you can call
        to save a branch / improve code generation and inlining when you know 
        that the vector is not getting bigger.
        
        2. Changed subclassing relationship in VectorBuffer to remove a call to
        fastFree() in the destructor for the inlineCapacity != 0 template
        specialization. This brings inline Vectors one step closer to true
        stack-allocated arrays.
        
        Also changed abort() to CRASH(), since the latter works better.

        This patch is a merge of KDE r670547, with substantial modification 
        for performance.
        
        It fixes do-while statements to evaluate to a value. (They used
        to evaluate to the empty value in all cases.) 

        It also fixes SourceElementsNode to maintain the value of abnormal 
        completions like "break" and "continue."
        
        It also re-works the main execution loop in SourceElementsNode so that
        it (1) makes a little more sense and (2) avoids unnecessary work. This 
        is a .28% speedup on command-line JS iBench.
