  > By convention, the stack is between the value of registers rbp (lower address) and rsp (higher address) and rsp increases when there are more stack frames added. We're on 64-bit Linux so each frame takes up 8 bytes.

  Stack frames grow in size based on local variables allocated on the stack. And $rbp and $rsp need not point at the correct places in the stack for leaf functions, at least on Linux, because it uses the System V ABI.
