This is a common construction in compiler-generated
machine code, if the first function calls another
just before return.

bar:    .cfi_startproc
         ... do something
         call foo
         ret

foo:    .. do more ..
         ret

If the functions have different stacks, there may be
a need to adjust the stack first before entering the ¨
second function.
