Question:

The following assembly-code function lets us determine the behavior of the instruction popq %rsp for x86-64:

1 2 3 5 6 7 8 text .globl poptest poptest: movq pushq popa movq movg ret %rap, %rdi $0xabcd %rsp %rap. %rax

We find this function always returns 0xabcd. What does this imply about the behavior of popq %rsp? What other Y86-64 instruction would have the exact same behavior?
