Wrapper for a set of expert tools for profiling, optimizing and debugging programs. Commonly used tools include memcheck, cachegrind, callgrind, massif, helgrind, and drd.
# To use the (default) Memcheck tool to show a diagnostic of memory usage by program:
valgrind program
# To use Memcheck to report all possible memory leaks of program in full detail:
valgrind --leak-check=full --show-leak-kinds=all program
# To use the Cachegrind tool to profile and log CPU cache operations of program:
valgrind --tool=cachegrind program
# To use the Massif tool to profile and log heap memory and stack usage of program:
valgrind --tool=massif --stacks=yes program
