           Summary: Replace jsFunctionVPtr compares with a type check on
                    the Structure.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


This will permit calls to still optimize to subclasses of JSFunction that have the correct type (but a different C++ vptr).
