# gprof
|
|
|
|
> Performance analysis tool for many programming languages.
|
|
> It profiles the function executions of a program.
|
|
> More information: <https://ftp.gnu.org/old-gnu/Manuals/gprof-2.9.1/html_mono/gprof.html>.
|
|
|
|
- Compile binary to default `a.out` with gprof information and run it to get `gmon.out`:
|
|
|
|
`gcc {{[-p|-pg]}} {{program.c}} && ./a.out`
|
|
|
|
- Run gprof on default `a.out` and `gmon.out` to obtain profile output:
|
|
|
|
`gprof`
|
|
|
|
- Run gprof on a named binary:
|
|
|
|
`gprof {{path/to/binary}} {{path/to/gmon.out}}`
|
|
|
|
- Suppress profile field's description:
|
|
|
|
`gprof {{[-b|--brief]}}`
|
|
|
|
- Display routines that have zero usage:
|
|
|
|
`gprof {{[-bz|--brief --display-unused-functions]}}`
