| PackageDescription | A memory debugger for x86-linux
Valgrind is a GPL'd tool to help you find memory-management problems in your
programs. When a program is run under Valgrind's supervision, all reads and
writes of memory are checked, and calls to malloc/new/free/delete are
intercepted.
.
Valgrind can debug more or less any dynamically-linked ELF Linux x86
executable, without modification, recompilation, or anything, as long as it
contains only classic x86 code (MMX/SSE/SSE2/3DNow! largely unsupported for
the moment). There is experimental support for programs using libpthread.
.
Valgrind provides a generic infrastructure for supervising the execution of
programs called "tools". This is done by providing a way to instrument
programs in very precise ways, making it relatively easy to support
activities such as dynamic error detection and profiling. Available tools
include Memcheck (a heavyweight memory checker), Cachegrind (a cache-miss
profiler), Addrcheck (a lightweight memory checker) and Helgrind (a
data-race detector), among others. |
