If it is about measuring relative performance of subprograms,
then one good approximation is kcachegrind.
(With compiler switch -fno-inline in particular).

If you can target the JVM using JGNAT, too, then this target
might allow injecting something.

The -fprofile* compiler switches might be interesting.
