- Compile binary to default `a.out` with gprof information and run it to get `gmon.out`:
|
||
|
|
|
||
|
|
`gcc -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`
|
||
|
|
|
||
|
|
- Display routines that have zero usage:
|
||
|
|
|
||
|
|
`gprof -bz`
