Hi Nicolas, I suppose the "small enough" is linked to the "!(div >> 32)" in your patch. Can I have the rationale which brought up this value, and if that value is universal across architectures (ie. x86/ppc/arm/...) ? And when you say "much faster", do you have figures to add to your commit message ?
