           Summary: DFG is too sloppy with register allocation
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fpizlo at apple.com


The DFG compiler sometimes keeps things in registers longer than it should, and doesn't assert aggressively enough that its register allocation discipline makes any sense.
