           Summary: DFG CSE should be able to eliminate unnecessary
                    flushes of arguments and captured variables
           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


We currently flush SetLocals to captured variables and arguments to inline functions.  But this is not necessary, if the code between the SetLocal and the Flush is speculated to not be clobbering.
