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.
