--- Comment #2 from Richard Guenther <rguenth at gcc dot gnu.org> 2010-11-30 12:22:26 UTC --- I think there is a dup somewhere. Note that IMHO disabling sse2 makes the code suspicious as it cannot fulfill the ABI (I think the kernel uses -mno-sse2 to disable use of SSE registers, not just non-move SSE instructions for example).
