           Summary: DFG should not assume that a variable is not aliased
                    to arguments just because of TearOffArguments
           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: fpizlo at apple.com


Currently the presence of TearOffArguments will force arguments aliasing to assume that arguments must be created. That's not the case; the TearOffArguments can be killed off.
