           Summary: Remove saving callFrameRegister to JITStackFram in
                    JITCompiler::compileFunction()
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: msaboff at apple.com

This is no longer needed as the stack check and arity check are now operations.  
Change is to delete two instances of
    move(stackPointerRegister, GPRInfo::argumentGPR0);
    poke(GPRInfo::callFrameRegister, OBJECT_OFFSETOF(struct JITStackFrame, callFrame) / sizeof(void*));
in Source/JavaScriptCore/dfg/DFGJITCompiler.cpp
