<dt><code>-d[</code><var>num</var><code>]</code><dt><code>--debug[=</code><var>num</var><code>]</code><dd>The ‘<samp><span class="samp">-d </span><var>num</var></samp>’ option specifies debugging options.
If <var>num</var> is not specified, enable all debugging.
See <a href="Debugging.html#Debugging">Debugging <code>gprof</code></a>.
<br><dt><code>-h</code><dt><code>--help</code><dd>The ‘<samp><span class="samp">-h</span></samp>’ option prints command line usage.
<br><dt><code>-O</code><var>name</var><dt><code>--file-format=</code><var>name</var><dd>Selects the format of the profile data files. Recognized formats are
‘<samp><span class="samp">auto</span></samp>’ (the default), ‘<samp><span class="samp">bsd</span></samp>’, ‘<samp><span class="samp">4.4bsd</span></samp>’, ‘<samp><span class="samp">magic</span></samp>’, and
‘<samp><span class="samp">prof</span></samp>’ (not yet supported).
<br><dt><code>-s</code><dt><code>--sum</code><dd>The ‘<samp><span class="samp">-s</span></samp>’ option causes <code>gprof</code> to summarize the information
in the profile data files it read in, and write out a profile data
file called <samp><span class="file">gmon.sum</span></samp>, which contains all the information from
the profile data files that <code>gprof</code> read in. The file <samp><span class="file">gmon.sum</span></samp>
may be one of the specified input files; the effect of this is to
merge the data in the other input files into <samp><span class="file">gmon.sum</span></samp>.
<p>Eventually you can run <code>gprof</code> again without ‘<samp><span class="samp">-s</span></samp>’ to analyze the
cumulative data in the file <samp><span class="file">gmon.sum</span></samp>.
<br><dt><code>-v</code><dt><code>--version</code><dd>The ‘<samp><span class="samp">-v</span></samp>’ flag causes <code>gprof</code> to print the current version
number, and then exit.
