|
- Use the (default) Memcheck tool to show a diagnostic of memory usage by `program`:
|
|
|
|
|
|
|
|
|
|
`valgrind {{program}}`
|
|
|
|
|
|
|
|
|
|
- Use Memcheck to report all possible memory leaks of `program` in full detail:
|
|
|
|
|
|
|
|
|
|
`valgrind --leak-check=full --show-leak-kinds=all {{program}}`
|
|
|
|
|
|
|
|
|
|
- Use the Cachegrind tool to profile and log CPU cache operations of `program`:
|
|
|
|
|
|
|
|
|
|
`valgrind --tool=cachegrind {{program}}`
|
|
|
|
|
|
|
|
|
|
- Use the Massif tool to profile and log heap memory and stack usage of `program`:
|
|
|
|
|
|
|
|
|
|
`valgrind --tool=massif --stacks=yes {{program}}`
|
