Please could you explain why the asm code was used?

I guess we were not aware that there was a builtin for it.

Are you sure this builtin is implemented everywhere?


Actually the builtin used in this patch is not supported in most CLANG

so I have reworked the patch to use builtin supported in both GCC and 
CLANG 3.4+.

Thanks,
