gprof

/usr/ccs/bin/gprof [options ] [objfile [pfile ]]

Solaris only. (Many other modern Unix systems also have it.) Display call-graph profile data of C programs. Programs compiled with the -xpg option of cc (-pg on other compilers) produce a call-graph profile file pfile , whose default name is gmon.out . The specified object file objfile (a.out by default) contains a symbol table that is read and correlated with pfile . See also prof and lprof .

Options

-a

Don't print statically declared functions.

-b

Brief; don't print field descriptions in the profile.

-c

Find the program's static call-graph. Call counts of 0 indicate static-only parents or children.

-C

Demangle C++ symbol names before printing them out.

-D

With this option, you supply one or more existing pfiles . Process the information in all specified profile files and produce profile file called gmon.sum that shows the difference between the runs. See also the -s option below.

-e name

Don't print the graph profile entry for the routine name . -e may be repeated.

-E name

Like -e above. In addition, during time computations, omit the time spent in name .

-f name

Print the graph profile entry only for routine name . -f may be repeated.

-F name

Like -f above. In addition, during time computations, use only the times of the printed routines. -F may be repeated, and it overrides -E .

-l

Don't print entries for local symbols.

-s

With this option, you supply one or more existing pfiles . Sum the information in all specified profile files and send it to a profile file called gmon.sum . Useful for accumulating data across several runs.

-z

Show routines that have zero usage. Useful with -c to find out which routines were never called.

- n

Only print the top n functions.
