           Summary: DFG JIT - loading of arguments should not be lazy
           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


This optimization is overly simplistic.  It only works because we never write out definitions to arguments (since we currently only compile single block functions).  Revert this for now, we may want to reintroduce something like this again in the future, but it will need to be aware how to schedule definitions to arguments versus lazy loads that have not yet been performed.
