How can a Z80 assembly program find out the address stored in the SP register?

I'm wondering how to write a program in Z80 assembler that discovers the value stored in the SP register. From what I've seen, the only instructions that touch the SP register are: LD SP, HL/IX/IY EX (SP), HL/IX/IY PUSH / POP However, none of them seem to load the address stored in the SP register anywhere. Is there a way to do it?
