-  * **''valgrind --db-attach=yes <your-program> <args>''** : to automatically attach gdb on errors
-  * **''valgrind --leak-check=full <program> <args>''** : to completely analyse memory leaks
-  * **''valgrind --tool=massif --time-unit=B <program> <args>'' + ''ms_print massif.<pid>''** : statistics about which functions are using memory
-  * **''valgrind --tool=callgrind <program-compiled-O2> <args>'' + ''kcachegrind callgrind.out.xxxx'' + ''calgrind_control''** : call profiling
-  * **''valgrind --tool=cachegrind <program-compiled-O2> <args>''** : CPU cache profiling in order to find cache misses
-Always do profiling with optimization options of compiler, or you could optimize things that the compiler already automatically does.
