            Bug ID: 186473
           Summary: [DFG] ArraySlice should support arguments types
           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

So frequent use of Array#slice is converting arguments to arrays by

var slice = Array.prototype.slice;


Our DFG pipeline only supports ArraySlice with JS Array types. JSC DFG should support ArraySlice with arguments.
