Memory debugging and profiling tool
Valgrind is a system for debugging and profiling un*x programs. With the tools that come with Valgrind, you can automatically detect many memory management and threading bugs, avoiding hours of frustrating bug-hunting, making your programs more stable. You can also perform detailed profiling, to speed up and reduce memory use of your programs. The Valgrind distribution includes 10 tools: - memcheck, the primary tool, a memory error detector - helgrind and drd, thread error detectors - callgrind and cachegrind, execution and cache profiling tools - massif, a memory tracker - dhat, a memory content profiler - lackey, an example of using the framework - none, does no instumentation and can check that Valgrind runs correctly - exp-bbv, and experimental profiling tool using sampling Valgrind was initially ported to FreeBSD by Doug Rabson.
