            Bug ID: 172358
           Summary: [DFG] Convert GetByVal(..., String:"499") to
                    GetByVal(..., Int32:499)
           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

If we can identify the constant values in DFG, we have a chance to convert GetByVal(..., String) to GetByVal(..., Int32).
If we do that, we have a chance to emit IC in DFG layer, and it is beneficial for FTL layer!
