        Bug 46065 - Unify implementation of ToInt32 and ToUInt32, don't use fmod.

        These methods implement the same conversion (see discussion in the notes
        of sections of 9.5 and 9.6 of the spec), only differing in how the result
        is interpretted.

        Date prototype is incorrectly using toInt32, and this is causing us to
        provide an output value indicating whether the input to ToInt32 was finite
        (the corresponding methods on Date are actually spec'ed to use ToInteger,
        not ToInt32).  This patch partially fixes this in order to remove this
        bogus output value, hoewever more work will be require to bring Date

        Alternatives that begin with ^ are tagged during parsing
        and rolled up in containing sub expression structs.
        After parsing, a regular expression flagged as containing
        a ^ (a.k.a. BOL) is processed further in optimizeBOL().
        A copy of the disjunction is made excluding alternatives that
        are rooted with BOL.  The original alternatives are flagged
        to only be executed once.  The copy of the other alternatives are
        added to the original expression.
        In the case that all original alternatives are flagged, there
        won't be any looping alternatives.
        The JIT generator will emit code accordingly, executing the
        original alternatives once and then looping over the
        alternatives that aren't anchored with a BOL (if any).

        Imprecise tracking of variable capture leads to overly pessimistic creation of activations
        https://bugs.webkit.org/show_bug.cgi?id=46020

        The old logic for track free and captured variables would cause us

        chain between a variable capture and its declaration.  We now track
        captured variables precisely which requires a bit of additional work

        The most substantial change is that the parsing routine needs to

        its body.

        Bug 44830 - In Array's prototype functyions we're incorrectly handing large index values

        We are in places casting doubles to unsigneds, and unsigneds to ints, without always check
        that the result is within bounds. This is problematic in the case of double-to-unsigned
        conversion because we should be saturating to array length.

        Also, the error return value from Array.splice should be [], not undefined.

        I don't see any security concerns here. These methods are spec'ed in such a way that they
        can be applied to non Array objects, so in all cases the (potentially bogus) indices are
        being passed to functions that will safely check accesses are within bounds.

        Bug 44745 - Number.toFixed/toExponential/toPrecision are inaccurate.

        These methods should be using a version of dtoa that can generate results accurate
        to the requested precision, whereas our version of dtoa is only currently able to
        support producing results sufficiently accurate to distinguish the value from any
        other IEEE-754 double precision number.

        This change has no impact on benchmarks we track.

        On microbenchmarks for these functions, this is a slight regression where a high
        precision is requested (dtoa now need to iterate further to generate a a greater
        number of digits), but with smaller precision values (hopefully more common) this
        improves performance, since it reduced the accurate of result dtoa is required,
        to produce, and removes the need to pre-round values before calling dtoa.

        [JSC] JavaScript parsing error when loading Equifax web page
        https://bugs.webkit.org/show_bug.cgi?id=42900

        '-->' is ostensibly only meant to occur when there is only
        whitespace preceeding it on the line.  However firefox treats
        multiline comments as a space character, so they are allowed.
        One side effect of the firefox model is that any line terminators
        inside the multiline comment are ignored, so

            foo/*
            */-->

        is treated as

            foo -->

        and so '-->' will not be a comment in this case.  Happily this simply
        means that to fix this issue all we need to do is stop updating
        m_atLineStart when handling multiline comments.

        Bug 44146 - Remove toDouble/toUInt32 methods from UString.

        These methods all implement JavaScript language specific behaviour, and as such
        are not suited to being on a generic string object.  They are also inefficient
        and incorrectly used, refactor & cleanup.  Uses of these methods really divide
        out into two cases.

        ToNumber:
        Uses of toDouble from JSString and from parseFloat are implementing ecma's
        ToNumber conversion from strings (see ecma-262 9.3.1), so UString::toDouble
        should largely just be moved out to a global jsToNumber function.  ToNumber is
        capable of recognizing either decimal or hexadecimal numbers, but parseFloat
        should only recognize decimal values.  This is currently handled by testing for
        hexadecimal before calling toDouble, which should unnecessary - instead we can
        just split out the two parts to the grammar into separate functions. Also,
        strtod recognizes a set of literals (nan, inf, and infinity - all with any
        capitalization) - which are not defined by any of the specs we are implementing.
        To handle this we need to perform additional work in toDouble to convert the
        unsupported cases of infinities back to NaNs.  Instead we should simply remove
        support for this literals from strtod.  This should provide a more desirable
        behaviour for all clients of strtod.

        Indexed properties:
        Uses of the toStrictUInt32 methods are were all converting property names to
        indices, and all uses of toUInt32 were incorrect; in all cases we should have
        been calling toUInt32.  This error results in some incorrect behaviour in the
        DOM (accessing property "0 " of a NodeList should fail; it currently does not).
        Move this method onto Identifier (our canonical property name), and make it
        always perform a strict conversion. Add a layout test to check NodeList does
        convert indexed property names correctly.

        Bug 44080 - String find/reverseFind methods need tidying up
        These methods have a couple of problems with their interface, and implementation.

        These methods take and int index, and return an int - however this is problematic
        since on 64-bit string indices may have a full 32-bit range.  This spills out into
        surrounding code, which unsafely casts string indices from unsigned to int. Code
        checking the result of these methods check for a mix of "== -1", "< 0", and
        "== notFound".  Clean this up by changing these methods to take an unsigned
        starting index, and return a size_t. with a failed match indicated by notFound.
        reverseFind also has a special meaning for the starting index argument, in that a
        negative index is interpreted as an offset back from the end of the string. Remove
        this functionality, in the (1!) case where it is used we should just calculate the
        offset by subtracting from the string's length.

        The implementation has a few problems too.  The code is not in webkit style, in
        using assorted abbreviations in variable names, and implementations of similar
        find methods with differing argument types were unnecessarily inconsistent. When
        find is passed const char* data the string would be handled as latin1 (zero
        extended to UTF-16) for all characters but the first; this is sign extended.
        Case-insensitive find is broken for unicode strings; the hashing optimization is
        not unicode safe, and could result in false negatives.

        Unify UString find methods to match String.

        Change UString constructors to match those in WTF::String.
        This changes behaviour of UString((char*)0) to create null
        strings, akin to UString() rather than UString::empty().
        (This matches String).  Remove unused constructors from
        UString, and add null-terminated UTF-16 constructor, to
        match String.  Move String's constructor into the .cpp to
        match UString.

        Qt port doesn't call any printf in String::format(...), consequently
        using __attribute__((format(printf,m,n))) is incorrect and causes

        don't have to rename all callers at once. Added a clear function.

        Bug 43817 - Remove UString::Rep
        UString::Rep has for a long time been replaced by UStringImpl (Rep
        remaining as a typedef).  UStringImpl has since been removed too
        (unified with StringImpl). Remove Rep, rename rep() to impl() and
        m_rep to m_impl.  Also add impl() method to Identifier, and rename
        its UString member from _ustring to m_string.

        Allow an assembler/macroassembler to compact branches to more concise forms when linking
        https://bugs.webkit.org/show_bug.cgi?id=43745

        This patch makes it possible for an assembler to convert jumps into a different
        (presumably more efficient) form at link time.  Currently implemented in the
        ARMv7 JIT as that already had logic to delay linking of jumps until the end of
        compilation already.  The ARMv7 JIT chooses between either a 4 byte short jump
        or a full 32-bit offset (and rewrites ITTT instructions as appropriate), so does
        not yet produce the most compact form possible.  The general design of the linker
        should make it relatively simple to introduce new branch types with little effort,
        as the linker has no knowledge of the exact form of any of the branches.

        Bug 43515 - Fix small design issues with PageAllocation, split out PageReservation.

        The PageAllocation class has a number of issues:
        * Changes in bug #43269 accidentally switched SYMBIAN over to use malloc/free to allocate
          blocks of memory for the GC heap, instead of allocating RChunks.  Revert this change in
          behaviour.
        * In order for PageAllocation to work correctly on WinCE we should be decommitting memory
          before deallocating.  In order to simplify understanding the expected state at deallocate,
          split behaviour out into PageAllocation and PageReservation classes.  Require that all
          memory be decommitted before calling deallocate on a PageReservation, add asserts to
          enforce this.
        * add many missing asserts.
        * inline more functions.
        * remove ability to create sub-PageAllocations from an existing PageAllocations object -
          this presented an interface that would allow sub regions to be deallocated, which would
          not have provided expected behaviour.
        * remove writable/executable arguments to commit, this value can be cached at the point
          the memory is reserved.
        * remove writable/executable arguments to allocateAligned, protection other than RW is not
          supported.
        * add missing checks for overflow & failed allocation to mmap path through allocateAligned.

        Fix for https://bugs.webkit.org/show_bug.cgi?id=43314.  The prior code
        was using the wrong "length" value to move array contents when adding
        space to the beginning of an array for an unshift() or similar
        operation.  Instead of using m_vectorLength, the length of the
        allocated JSValue array, the code was using m_length, the declared

        When JSArray is allocated for the vptr stealing hack, it's not allocated
        in the heap, so the JSArray constructor can't safely call Heap::heap().

        Change to keep returned pointer from malloc family functions to
        quiet memory leak detect.  The pointer is saved in the new m_allocBase
        member of the ArrayStorage structure.  This fixes the issue found in 
        https://bugs.webkit.org/show_bug.cgi?id=43229.

        As part of this change, we use m_allocBase when reallocating and
        freeing the memory associated with ArrayStorage.

        GC should reclaim garbage even when new objects are not being allocated rapidly

        Added a callback in JavaScriptCore that gets triggered after an
        allocation causes the heap to reset.  This is useful for adding a
        timer that will trigger garbage collection after the "last" allocation.

        Also needed was to add lock and unlock methods to JSLock that needed
        only a JSGlobalData object versus an ExecState object.

        Bug 43089 - Cleanup JIT related switched in Platform.h

        The code the enable to JIT checks every permutation of platform & OS individually, but
        now the JIT is enabled on the majority much all x86/x86-64/ARM/MIPS systems.  It should
        be cleaner to just enable by default on these platforms, and explicitly disable on configs
        that don't aren't supported.

        Also, rename ENABLE_JIT_OPTIMIZE_MOD to ENABLE_JIT_USE_SOFT_MODULO.  I always find this
        confusing since enabling this "optimization" would be possible, but would be a regression
        on x86/x86-64 systems!  I think it's clearer to reserve "JIT_OPTIMIZE" for compiler
        technologies applicable to all platforms, and make a more optional behaviour like this a
        "USE".

        WebKit on Windows should build optionally with an unversioned ICU DLL
        https://bugs.webkit.org/show_bug.cgi?id=42722
        <rdar://problem/8211743> JavaScriptCore needs to link against unversioned ICU
        
        Dynamically create a new header, ICUVersion.h, as part of build-generated-files.sh.
        Header contains a preprocessor define (U_DISABLE_RENAMING) indicating to ICU whether the ICU API
        should be namespaced with the current ICU version number. Proper value is determined
        by checking for the presence of libicuuc.lib, the unversioned copy of ICU.
        
        To get the proper value for U_DISABLE_RENAMING into all source files, we force
        the include of ICUVersion.h (our generated header) via the compiler options.
        
        Since the versioned and unversioned ICU have different filenames (libicuuc.lib vs icuuc.lib)
        we copy the ICU lib to an intermediate location under obj with a common name. This
        allows us to link properly with either without adding a new build configuration.

        Bug 42182 - Change how numeric compare functions are detected

        There are three problems with the current mechanism:
          * It requires that a function executable be bytecode compiled without
            being JIT generated (in order to copy the bytecode from the numeric
            compare function).  This is a problem since we have an invariant when
            running with the JIT that functions are never bytecode compiled without
            also being JIT generated (after checking the codeblock we assume the
            function has JIT code).  To help maintain this invariant 
          * This implementation will prevent us from experimenting with alternate
            compilation paths which do not compile via bytecode.
          * It doesn't work.  Functions passing more than two arguments will match
            if they are comparing their last two arguments, not the first two.
            Generally the mapping back from bytecode to semantics may be more
            complex then initially expected.

        REGRESSION: Crash at JSC::JIT::privateCompile(JSC::MacroAssemblerCodePtr*)
        https://bugs.webkit.org/show_bug.cgi?id=41763

        There are two parts to this patch, the first is to fix the actual
        problem.  When calling copyStringWithoutBOMs on a string we know
        to contain BOMs we return a value indicating that there are no
        BOMs.

        The second part of this fix is simply to harden the path that
        led to a crash when parsing failed.

        Fix the constant encoding in data transfer instructions on ARM
        https://bugs.webkit.org/show_bug.cgi?id=42166

        The getImm function is designed to produce modified immediate constant
        for data processing instructions. It should not be used to encode
        any constant for data transfer. In the current situation there is no
        way to use any immediate constant for data transfer. So, the moveImm
        function is the desired method to pass the offset value to the data
        transfer instructions.

        Property declarations in an object literal should not consider the prototype chain when being added to the new object
        https://bugs.webkit.org/show_bug.cgi?id=41929

        To fix this all we need to do is ensure that all new properties are
        added with putDirect rather than a fully generic call to put.  This
        is safe as an object literal is by definition going to produce a
        completely normal object.

        Rather than duplicating all the put_by_id logic we add an additional
        flag to op_put_by_id to indicate it should be using putDirect.  In
        the interpreter this adds a runtime branch, but in the jit this is
        essentially free as the branch is taken at compile time.  This does
        actually improve object literal creation time even in the interpreter
        as we no longer need to walk the prototype chain to verify that the
        cached put is safe.

        We still emit normal put_by_id code when emitting __proto__ as we want
        to get the correct handling for changing the prototype.

        Sunspider claims this is a 0.7% speedup which is conceivably real due
        to the performance improvement in object literals, but I suspect its
        really just the result of code motion.

        Make it possible to have both the JIT and Interpreter available in a single build
        https://bugs.webkit.org/show_bug.cgi?id=41722

        Separate the concept of !ENABLE(JIT) and ENABLE(INTERPRETER) and make it possible
        to have both JIT and INTERPRETER enabled at the same time.  This doesn't add
        support for mix mode execution, but it does allow a single build to contain all
        the code needed to use either the interpreter or the jit.

        If both ENABLE(INTERPRETER) and ENABLE(JIT) are true then setting the environment
        variable JSC_FORCE_INTERPRETER will force JSC to use the interpreter.

        This patch basically consists of replacing !ENABLE(JIT) with ENABLE(INTERPRETER),
        or converting #if ENABLE(JIT) ... #else ... into #if ENABLE(JIT) ... #endif
        #if ENABLE(INTERPRETER), etc.  There are also a few functions that need to be
        renamed to resolve return type ambiguity.

        Move BOM handling out of the lexer and parser
        https://bugs.webkit.org/show_bug.cgi?id=41539

        Doing the BOM stripping in the lexer meant that we could
        end up having to strip the BOMs from a source multiple times.
        To deal with this we now require all strings provided by
        a SourceProvider to already have had the BOMs stripped.
        This also simplifies some of the lexer logic.

        Bug 41238 - RegExp performance slow on Dromaeo benchmark

        Other javascript engines appear to cache prior results of regular 
        expression operations.

        Suggest adding some sort of caching mechanism to regular expression 
        processing.

        Added a single entry cache of match() results to RegExp class.

        Also added performance improvements to UString == operator.
        First check the impls for equality.  Then get the length of
        each of the non-null impls.  Next check the sizes for equality.
        Then check the data for the case of different impls that point 
        to the same data (most likely due to substrings from the beginning of
        another string).  Lastly we check the underlying data for equality.

        Custom-written JavaScript parser
        https://bugs.webkit.org/show_bug.cgi?id=34019

        Implement a recursive descent parser similar to that used by V8 and
        SpiderMonkey.  Greater than 2x improvement in SunSpider parsing tests.

        The parser consists of a JSParser class that uses a TreeBuilder to actually
        build the AST.  There are currently two builders -- the ASTBuilder and
        SyntaxChecker which separate the job of building an AST for code generation
        and simply checking syntactic correctness.

        There's still some less than ideal code remaining in the parser to allow
        us to retain the existing lexing code with minimal changes.  We'll tidy
        this up at a later date.

        Need to ensure that we grow the RegisterFile when creating a callframe for host code
        https://bugs.webkit.org/show_bug.cgi?id=40858
        <rdar://problem/8108986>

        In the past the use of the callframe in hostcode was much more
        limited.  Now that we expect the callframe to always be valid
        we need to grow the RegisterFile so that this is actually the
        case.  In this particular case the problem was failing to grow
        the registerfile could lead to a callframe that extended beyond
        RegisterFiler::end(), so vm re-entry would clobber the callframe
        other scenarios could also lead to badness.

        I was unable to construct a simple testcase to trigger badness,
        and any such testcase would be so dependent on exact vm stack
        layout that it would be unlikely to work as a testcase following
        any callframe or register allocation changes anyway.

        Thankfully the new assertion I added should help to catch these
        failures in future, and triggers on a couple of tests currently.

        [Qt] Implement the simple text code path.
        https://bugs.webkit.org/show_bug.cgi?id=40077

        Remove the FONT_FAST_PATH macro and use the Qt's
        fast text implementation instead of the one of WebKit.

        The Qt::TextBypassShaping flag is used to tell Qt to
        only use the glyph advances.

        Qt 4.7 is needed to get this flag thus the complex path is always
        used if QtWebKit is compiled against an earlier version.

        Contrary to the WebKit's implementation, the complex code path
        is taken if the text is RightToLeft, justified or is formatted
        with non-zero letter or word spacing.

        Bug 40214 - Clean up error construction / throwing in JSC.
        
        The one egregious insanity here is that creating an error requires
        a VM-entry-esqe-host call (the string argument is wrapped as a JS
        object & pushed on the RegisterFile, then unwrapped back to a
        UString).  Changing this also means you only require a global
        object, not an ExecState, to create an error.

        The methods to create error objects are also parameterized
        requiring a switch on the type, which can be made cleaner and
        faster by moving to a separate method per error type.  Code to add
        divot information to error had been duplicated, and is coalesced
        back into a single function.

        Convenience methods added to create & throw type & syntax error
        with a default error message, since this is a common case.

        Also, errors are currently thrown either using
        "throwError(exec, error)" or "exec->setException(error)" - unify
        on the former, since this is more commonly used.  Add
        "throwVMError(exec, error)" equivalents, as a convenience for
        cases where the result was being wrapped in "JSValue::encode(...)".

        Simplified the host calling convention.
        
        22.5% speedup on 32-bit host function calls. 9.5% speedup on 64-bit host
        function calls.
        
        No change on SunSpider.
        
        All JS calls (but not constructs, yet) now go through the normal JS
        calling convention via the RegisterFile. As a result, the host calling
        convention, which used to be this

            JSValue (JSC_HOST_CALL *NativeFunction)(ExecState*, JSObject*, JSValue thisValue, const ArgList&)
            
        is now this

            JSValue (JSC_HOST_CALL *NativeFunction)(ExecState*)
            
        Callee, 'this', and argument access all hapen relative to the ExecState*,
        which is a pointer into the RegisterFile.
        
        This patch comes in two parts.
        
        PART ONE: Functional code changes.
        
        * wtf/Platform.h: Disabled optimized calls on platforms I didn't test.
        We can re-enable once we verify that host calls on these platforms are
        correct.

        * debugger/DebuggerCallFrame.cpp:
        (JSC::DebuggerCallFrame::functionName):
        (JSC::DebuggerCallFrame::calculatedFunctionName): Updated for change to
        ExecState::callee().

        (JSC::DebuggerCallFrame::thisObject): Updated for removal of ExecState::thisValue().

        * interpreter/CallFrame.cpp:
        * interpreter/CallFrame.h:
        (JSC::ExecState::callee):
        (JSC::ExecState::scopeChain):
        (JSC::ExecState::init): Changed callee() to be JSObject* instead of
        JSFunction* -- now, it might be some other callable host object.

        (JSC::ExecState::hostThisRegister):
        (JSC::ExecState::hostThisValue):
        (JSC::ExecState::argumentCount):
        (JSC::ExecState::argumentCountIncludingThis):
        (JSC::ExecState::argument):
        (JSC::ExecState::setArgumentCountIncludingThis):
        (JSC::ExecState::setCallee): Added convenient accessors for arguments
        from within a host function. Removed thisValue() because it was too
        tempting to use incorrectly, and it only had one or two clients, anyway.

        * interpreter/Interpreter.cpp:
        (JSC::Interpreter::callEval): Updated for removal of ExecState::thisValue().

        (JSC::Interpreter::throwException): Be sure to shrink the register file
        before invoking the exception handler, to reduce the chances that the
        handler will re-throw in the case of stack overflow. (Re-throwing is now
        more likely than it used to be, since standardizing the calling convention
        implicitly added stack overflow checks to some places where they used to be missing.)

        (JSC::Interpreter::execute): Clarified the scope of DynamicGlobalObjectScope.
        Updated for CallFrame::init API change.

        (JSC::Interpreter::executeCall): Clarified scope of DynamicGlobalObjectScope.
        Updated for CallFrame::init API change. Added support for calling a host
        function.

        (JSC::Interpreter::executeConstruct): Clarified scope of DynamicGlobalObjectScope.
        Updated for CallFrame::init API change. 

        (JSC::Interpreter::prepareForRepeatCall): Updated for CallFrame::init API change. 

        (JSC::Interpreter::privateExecute): Updated for CallFrame::init API change.
        Added some explicit JSValue(JSObject*) initialization, since relaxing
        the JSFunction* restriction on callee has made register types more ambiguous.
        Removed toThisObject() conversion, since all callees do it themselves now.
        Updated host function call for new host function signature. Updated for
        change to ExecState::argumentCount() API.

        * interpreter/Register.h:
        (JSC::Register::):
        (JSC::Register::operator=):
        (JSC::Register::function): Changed callee() to be JSObject* instead of
        JSFunction* -- now, it might be some other callable host object.

        * jit/JITOpcodes.cpp:
        (JSC::JIT::privateCompileCTINativeCall):
        * jit/JITOpcodes32_64.cpp:
        (JSC::JIT::privateCompileCTINativeCall): Deleted a bunch of code that
        set up the arguments to host functions -- all but one of the arguments
        are gone now. This is the actual optimization.

        * jit/JITStubs.cpp:
        (JSC::DEFINE_STUB_FUNCTION): Updated for ExecState and Register API
        changes noted above. Removed toThisObject() conversion, since all callees
        do it themselves now.
        
        * runtime/ArgList.h:
        (JSC::ArgList::ArgList): ArgList is getting close to unused. Added a
        temporary shim for converting from ExecState* to ArgList where it's still
        necessary.

        * runtime/Arguments.h:
        (JSC::Arguments::getArgumentsData):
        (JSC::Arguments::Arguments): Updated for ExecState and Register API
        changes noted above. 

        * runtime/CallData.cpp:
        (JSC::call): Changed call always to call Interpreter::executeCall, even
        for host functions. This ensures that the normal calling convention is
        set up in the RegsiterFile when calling from C++ to host function.

        * runtime/CallData.h: Changed host function signature as described above.

        * runtime/ConstructData.cpp:
        (JSC::construct): Moved JSFunction::construct code here so I could nix
        JSFunction::call and JSFunction::call. We want a JSFunction-agnostic
        way to call and construct, so that everything works naturally for non-
        JSFunction objects. 

        * runtime/JSFunction.cpp:
        (JSC::callHostFunctionAsConstructor):
        * runtime/JSFunction.h: Updated for ExecState and Register API changes
        noted above. Nixed JSFunction::call and JSFunction::construct, noted above.
 
        * runtime/JSGlobalObject.cpp:
        (JSC::JSGlobalObject::init): Ditto.

        PART TWO: Global search and replace.
        
        In the areas below, I used global search-and-replace to change
            (ExecState*, JSObject*, JSValue, const ArgList&) => (ExecState*)
            args.size() => exec->argumentCount()
            args.at(i) => exec->argument(i)

        Bug 39795 - Add support for YARR JIT generation of greedy quantified parens at the end of the main disjunction.
        (relanding r60267)

        If the last item in a main disjunction is a quantified set of parentheses,
        this is easier to code generate for than the general case for quantified
        parentheses. This is because we never need to backtrack into the parentheses
        - the first match will be the final and accepted match.

        This patch also somewhat reverts a recent change to when fallback to PCRE
        occurs. At the minute the compiler is tracking on patterns which will
        require JIT fallback. This is handy from a performance perspective (it saves
        the failed attempt at JIT compilation), but it means introducing knowledge
        of the JITs capabilities into the other layers of the regex compilers. For
        the specific feature of back-references, add a flag tracking their presence
        on the pattern, and make these expressions fallback without attempting to
        JIT. For parentheses, return to detecting which cases are have or have not
        been handled during JIT compilation.

        Presently, as soon as op-call strays off the hot path we set up a set of values on
        the stack to be passed as arguments to cti functions, in case any should be called.

        Instead, hoist the setup of the callframe to happen slightly sooner, and make the
        cti functions to compile & check arity read these values from the callframe. This
        allows up to remove the deprecated methods to manually set up cti arguments, rather
