| <title>Nulgrind: the ``null'' tool</title> |
| <subtitle>A tool that does not very much at all</subtitle> |
| |
| <para>Nulgrind is the minimal tool for Valgrind. It does no |
| initialisation or finalisation, and adds no instrumentation to |
| the program's code. It is mainly of use for Valgrind's |
| developers for debugging and regression testing.</para> |
| |
| <para>Nonetheless you can run programs with Nulgrind. They will |
| run roughly 5 times more slowly than normal, for no useful |
| effect. Note that you need to use the option |
| <computeroutput>--tool=none</computeroutput> to run Nulgrind |
| (ie. not <computeroutput>--tool=nulgrind</computeroutput>).</para> |
