            Bug ID: 162000
           Summary: [DFG] Array.isArray should have DFG node
    Classification: Unclassified
           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

After the generator patch & Map patch, isArray becomes hot function in ES6SampleBench's Basic.
Array.isArray is frequently used to distinguish between object and array. That should be handled in DFG.
