            Bug ID: 231276
           Summary: DFG::ArrayMode::refine() should remember
                    out-of-boundness for GetByVal on typed arrays
           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: rmorisset at apple.com

Currently this information is only preserved for accesses on typed arrays if it is a PutByVal.
Neither Saam nor me can see a reason for this, and the original commit that added this code has no explanation either.
