            Bug ID: 218646
           Summary: Use address diversified PAC to ensure the integrity of
                    opcode maps.
           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: mark.lam at apple.com

One reason for doing this is because space in the JSCConfig is premium, and may hurt RAMification scores whenever we add new opcodes.  My putting the opcode maps in dirty global memory, we still use less memory because dirty global memory does not incur internal fragmentation like the JSConfig does.
