           Summary: DFG speculative JIT contains a FIXME for rewinding
                    speculative code generation that has already been
                    fixed
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fpizlo at apple.com


The DFG speculative JIT may perform a speculation that turns out to be statically false.  In this case, speculative code generation is rolled back.  Despite the fact that this feature is already implemented, there is still a FIXME in DFGSpeculativeJIT.h that indicates that we should implement this already-implemented feature.  Additionally, the same code path also generates a speculation check despite the fact that any code generated by this path will be rewound.
