            Bug ID: 151793
           Summary: Polymorphic operands in operators coerces downstream
                    values to double.
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mark.lam at apple.com

With the addition of support for polymorphic operands to operators in the DFG and FTL, the PredictionPropagationPhase may now coerce downstream math operations to use double type.  This may result in performance pathologies.  We should investigate a way to mitigate this.
