--- Comment #2 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
32-bit division by constant relies on a 32x32->64 bit multiply.  So it seems
reasonable that a 64-bit division would need a 64x64->128 bit multiply.  We
don't have an instruction for that on arm nor does gcc support 128-bit integer
types on a 32-bit compiler.
