<title>Nulgrind: the minimal Valgrind tool</title>
|

<para>To use this tool, you must specify
|
|
<option>--tool=none</option> on the Valgrind
|

command line.</para>

<para>Nulgrind is the simplest possible Valgrind tool. It performs no
|
|
instrumentation or analysis of a program, just runs it normally. 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 <option>--tool=none</option> to run
|
|
Nulgrind (ie. not <option>--tool=nulgrind</option>).</para>
