           Summary: DFG::shouldSpeculate methods are too complicated
           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


The DFG::shouldSpeculateXYZ methods have some hold-overs from the static speculation days, as well as some hold-overs from when nodes did not remember their predictions after propagation.  They should now be simplified to just use the node's prediction, instead of also querying if it's a constant, what its generation info is, etc.
