gprof
GNU gprof and Berkeley Unix gprof use the same data
file `gmon.out', and provide essentially the same information. But
there are a few differences.
gprof uses a new, generalized file format with support
for basic-block execution counts and non-realtime histograms. A magic
cookie and version number allows gprof to easily identify
new style files. Old BSD-style files can still be read.
See section Profiling Data File Format.
gprof lists the function as a
parent and as a child, with a calls field that lists the number
of recursive calls. GNU gprof omits these lines and puts
the number of recursive calls in the primary line.
gprof still lists it as a subroutine of functions that call it.
gprof accepts the `-k' with its argument
in the form `from/to', instead of `from to'.
gprof prints all of their counts, separated by commas.
gprof prints blurbs after the tables, so that you can see the
tables without skipping the blurbs.
