           Summary: change property map data structure for less memory use,
                    better speed
           Product: WebKit
           Version: 523.x+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: darin at apple.com


This optimization is giving me a 0.8% speed-up on SunSpider, although it does
slow down bitwise-and because that is almost exclusively a test of unoptimized
global variable access.
