           Summary: Optimization triggers in the old JIT may sometimes
                    fire repeatedly even though there is no optimization
                    to be done
           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


If cti_optimize_from_ret fires but finds it has no work to do, it currently just returns.  This means that it will fire again the next time even though there is still likely to be no work to do.  This may cause slow downs since cti_optimize_from_ret is a stub call.
