            Bug ID: 179323
           Summary: [DFG] InternalFunction lowering should be also done
                    after arguments elimination phase
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: utatane.tea at gmail.com

Due to the lack of prediction information, we do not inline InternalFunctions in DFGByteCodeParser if it is called in a form of vararg.
But this vararg call is sometimes eliminated if argument elimination phase converts Vararg calls to usual calls.
