Any time the epilogue is multi-instruction, the compiler is free to
schedule instructions in the middle of it, and GCC does.  Plus it
varies based on the size of the stack frame.  On some platforms an
epilogue is hard to distinguish from an indirect function call.
Sibling calls have mini-epilogues in front of them, too.  And there
can be lots of copies of the epilogue, and they don't have to be at
the end of the function; they can be inlined at return sites.

So yes, it's a little harder than that :-)
