If -finstrument-functions work in gcj you might want to try the profiler
in eazel-tools/profiler in the gnome cvs tree
(:pserver:anonymous@anoncvs.gnome.org:/cvs/gnome). It is works with
threads and shared libraries, and does non-sampling profiling. It's not
perfect (it takes a lot of memory), but it works good enough for me to
profile Mozilla.
