           Summary: Either remove the GetMethod node from the DFG backend,
                    or find a use for it
           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
        Depends on: 73175


The GetMethod node is no longer emitted by the DFG's byte code parser.  It may be that this node could still be useful for situations where we're not confident enough in the structure of the base of a GetById to issue CheckStructure nodes, but we've got enough confidence in its monomorphism that we don't want to drop all the way down to a GetById.

But most likely, if we don't find a use for GetMethod in the near term, we should just remove the supporting code.
