           Summary: bitops-bitwise-and.js in SunSpider is misleading
           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: ian.eng.webkit at gmail.com


I run the test, most time were spent on accessing a global variable (read and
write): bitwiseAndValue.
If we move the code into a function and declare bitwiseAndValue be a local, the
execution is reduced from 72ms to 10ms.

To make the benchmark name accurate, either it should be renamed to 'access'
category as Maciej suggested, or move the code into a function and declare the
varaible as a local.
