           Summary: Extend Safe to Execute capabilities for NativeCall and
                    NativeConstruct
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Enhancement
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mmirman at apple.com


Currently NativeCall and NativeConstruct are considered always unsafe to execute by the DFG which prevents certain optimizations.  Often there is a check which when 
completed makes them safe to execute.  Need to refine the cases where they are safe to execute.
