           Summary: DFG should know exactly why recompilation was
           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 DFG can update predictions on OSR failure, which, in the case of recompilation, greatly reduces the likelihood that the DFG will repeat a broken type speculation on recompilation.  But the same is not true of slow case profiles.
