           Summary: The JIT's handling of JSImmediate values is broken on
                    x86-64.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


The upper bits of the immediate should be a sign extension of the low 32-bit
word; the 32-bit operations on x86-64 zero the upper portion of the register.
