           Summary: Make SSE detection less bad
           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


* should check on windows,
* should not need check for SSE2 on OS X (ALWAYS_INLINE return true),
* should be checking for the correct SSE version, as required,
* should be asserting required SSE version is available when emitting
instructions in X86Assembler,

Probably move the SSE checking to something like kjs/CPUSpecifics.h  (in the
longer term may need separate files per architecture.
