            Bug ID: 192966
           Summary: DFGByteCodeParser rules for bitwise operations should
                    consider type of their operands
           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: ticaiolima at gmail.com

Current implementation relies into `getPrediction()` to emit ArithBitOp or ValueBitOp. This rule is not efficient because there cases where we don't have profiling information and we sendup always emitting OSRExit or ValueBitOp.
