gprof and Berkeley Unix
gprof use the same data
file `gmon.out', and provide essentially the same information. But
there are a few differences.
gproflists the function as a parent and as a child, with a
callsfield that lists the number of recursive calls. GNU
gprofomits these lines and puts the number of recursive calls in the primary line.
gprofstill lists it as a subroutine of functions that call it.
gprofprints blurbs after the tables, so that you can see the tables without skipping the blurbs.
