        JSC TimeoutChecker::didTimeOut overflows on ARM

        Make getCPUTime() return values relative to the first call.
        The previous implementation relied on simply on currentTime(), which
        return a time since epoch and not a time since the thread started. This

        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 42207 - Clean up interface to compile executables, always check for exceptions

        Presently interface to compile executable is inconsistent between eval/program and
        function code, and is error prone in allowing a caller to byte compile without JIT
        compiling an executable (we rely on all executables with codeblocks having JIT code).
        Unify on an interface where all compilation is performed by a single compile (with
        ForCall|ForConstruct variants) method, and make all clients check for errors.

        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.

        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

        Move BOM handling out of the lexer and parser

        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.

        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.

        Only one character lookahead should be enough for the lexer
        https://bugs.webkit.org/show_bug.cgi?id=41213

        The lexer had 4 character lookahead before, which required
        a complex shifting mechanism. This can be improved by using
        only one character lookahead for most decisions, and a
        peek() function as a fallback when it is absolutely necessary.

        [Qt] QScriptValue should have API for accessing object properties

        still doesn't support the ResolveLocal parameter, it is already useful
        for testing the API.

        The tests from upstream QtScript weren't imported since most of them

        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.

        Make JSC more resilient in the face of parse failures

        A number of recent bugs have occurred due to issues like miscounting

        logic hardens JSC in the face of these errors, and has no impact on

        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.

        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()

        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.

        - 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.

        18% progression on tagcloud, ~1.5% overall on sunspidey.

        Build fix for JSFunction
        https://bugs.webkit.org/show_bug.cgi?id=39658

        MSVC can't compile one of JSFunction constructors when JIT is disabled.
        "PassRefPtr<NativeExecutable>" causes the compile error as NativeExecutable is not defined. 
        Add ENABLE(JIT) guard to the constructor.

        Bug 39643 - Clean up code generation in the JIT of stub function calls for op_call.

        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
        than using JITStubCall.h.
