# Module Sys.Immediate64

    module Immediate64: sig .. end

This module allows to define a type `t` with the `immediate64` attribute. This attribute means that the type is immediate on 64 bit architectures. On other architectures, it might or might not be immediate.

    module type Non_immediate = sig .. end

    module type Immediate = sig .. end

    module Make: functor (Immediate : Immediate) -> functor (Non_immediate : Non_immediate) -> sig .. end
