[Webkit-unassigned] [Bug 14602] New: JSC/WTF: fastMalloc doesn't use bsr under VC

[bugzilla-daemon at webkit.org]

http://bugs.webkit.org/show_bug.cgi?id=14602

           Summary: JSC/WTF: fastMalloc doesn't use bsr under VC
           Product: WebKit
           Version: 522+ (nightly)
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Trivial
          Priority: P5
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: 808caaa4.8ce9.9cd6c799e9f6 at gmail.com


With VC, fastMalloc.cpp doesn't use inline assembly for LgFloor().

#if defined(_MSC_VER) && !defined(_68K_) && !defined(_MPPC_) && !defined(_X86_)
&& !defined(_IA64_) && !defined(_AMD64_) && defined(_M_IX86)
static inline int LgFloor(size_t n) {
        __asm xor eax,eax
        __asm not eax
        __asm bsr eax,n
}
#endif


p.s.
In WebKit.dll, do_malloc() and do_free() expands as ALWAYS_INLINE everywhere
and costs binary sizes.
Is this intended?
