QEMU is a dynamic binary translator. You don't know the next block
without executing the current block. It's not possible to translate a
whole program without executing it - remember it can load shared
libraries, use self-modifying code, or just employ indirect jumps which
you cannot analyze statically.
In the general case it's not possible. Can you explain why you're
trying to do this?
