Can I force gcc not to optimize calling to leaf functions with `-O2' option?

What you describe is not an optimization of calling leaf functions,
it's an optimization when the last action a function takes is to call
another function. There are a couple of names for this optimization.
gcc calls it a sibling call. The option to turn it off is
-fno-optimize-sibling-calls.
