           Summary: DFG JIT - don't allocate virtual registers to nodes
                    with no result
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


We currently allocate virtual registers to nodes which have no result - these are clearly unused, and may result in us allocating a larger than necessary stack frame.
