-Oname
--file-format=name
auto' (the default), `bsd', `4.4bsd', `magic', and
`prof' (not yet supported).
-s
--sum
-s' option causes gprof to summarize the information
in the profile data files it read in, and write out a profile data
file called `gmon.sum', which contains all the information from
the profile data files that gprof read in.  The file `gmon.sum'
may be one of the specified input files; the effect of this is to
merge the data in the other input files into `gmon.sum'.
Eventually you can run gprof again without `-s' to analyze the
cumulative data in the file `gmon.sum'.
-v
--version
-v' flag causes gprof to print the current version
number, and then exit.
