Valgrind

Valgrind is a suite of tools for debugging and profiling Linux programs.

The Callgrind tools allow profiling of a program.

When it is used with "--dump-instr=yes --trace-jump=yes" and the result is displayed with [1], you can see:

• function call tracing
• executed calltree graphing
• jmp tracing and graphing

Example

$ valgrind --tool=callgrind --dump-instr=yes --trace-jump=yes ffplay
$ kcachegrind callgrind.$pid
