            Bug ID: 212765
           Summary: Add a Thread Specific Buffer for LinkBuffer when
                    Compacting
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: msaboff at apple.com

Similar to https://bugs.webkit.org/show_bug.cgi?id=212562, we should add a Thread Local Buffer for LinkBuffer::copyCompactAndLinkCode().  When compacting JIT code, for most CPU types we need a second data buffer.  We should make this buffer a thread local just like we did for the AssemblerBuffer in 212562.
