lprof

lprof [options]
lprof -m files [-T] -d out

SVR4 only. Display a program's profile data on a line-by-line basis. Data includes a list of source files, each source-code line (with line numbers), and the number of times each line was executed. By default, lprof interprets the profile file prog.cnt. This file is generated by specifying cc -ql when compiling a program or when creating a shared object named prog (default is a.out). The PROFOPTS environment variable can control profiling at runtime. See also prof and gprof.

Options

-c file

Read input profile file instead of prog.cnt.

-d out

Store merged profile data in file out. Must be used with -m.

-I dir

Search for include files in dir as well as in the default place (/usr/include).

-m files

Merge several profile files and total the execution counts. files are of the form f1.cnt, f2.cnt, f3.cnt, etc., where each file contains the profile data from a different run of the same program. Used with -d.

-o prog

Look in the profile file for a program named prog instead of the name used when the profile file was created. -o is needed when files have been renamed or moved.

-p

Print the default listing; useful with -r and -s.

-r list

Used with -p to print only the source files given in list.

-s

For each function, print the percentage of code lines that are executed.

-T

Ignore timestamp of executable files being profiled. Normally, times are checked to insure that the various profiles were made from the same version of an executable.

-V

Print the version of lprof on standard error.

-x

Omit execution counts. For lines that executed, show only the line numbers; for lines that didn't execute, print the line number, the symbol [U], and the source line.
