[Webkit-unassigned] [Bug 140554] New: Remove the the captured variable hole from the stack, and make SymbolTable capable of telling you whether any given entry is a captured entry (i.e. activation index) or stack entry (i.e. VirtualRegister)

            Bug ID: 140554
           Summary: Remove the the captured variable hole from the stack,
                    and make SymbolTable capable of telling you whether
                    any given entry is a captured entry (i.e. activation
                    index) or stack entry (i.e. VirtualRegister)
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: fpizlo at apple.com

This implies fixing DFG::clobberize() to know that VirtualRegisters and captured variables aren't necessarily the same thing.
