           Summary: Move arity check into callee.
           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 can reduce the size of the virtual call trampolines by moving the arity check into the callee functions.  As a following step we will be able to remove the check for native function / codeblocks by performing translation in a lazy stub.
