I'm not sure what gprof does but you can use pixie(1) and prof(1) to
profile your application.  Take your application, foo.  To prepare
you application for profiling, use:

	pixie foo

To collect the profile data, run the file "foo.pixie" which was created
by "pixie foo".

prof has numerous options for view the profile data.  To get "call graph"
statistics, use "prof -pixie -invocations foo".

Something useful I have found using "prof" is to use "-quit 1%".  What you
might do is this.

	prof -pixie -quit 1% foo	# find out which routine(s) are most
					# heavily used

	prof -pixie -invocations -only most_heavily_used_function
					# to find out which routines call
					# the most_heavily_used_function
					# and how many times it is called
					# from each of those functions

Hope this helps.
