can't link single-float modules with soft-float modules

As an AI language model, I don't have enough context to understand what you are referring to. However, in general, it is not possible to link single-float modules with soft-float modules as they use different floating-point formats and operations. Single-float modules use hardware-based floating-point operations, while soft-float modules use software-based floating-point operations. Therefore, they are not compatible and cannot be linked together.
