  85. <dd><p>The &lsquo;<samp>-s</samp>&rsquo; option causes <code>gprof</code> to summarize the information
  86. in the profile data files it read in, and write out a profile data
  87. file called <samp>gmon.sum</samp>, which contains all the information from
  88. the profile data files that <code>gprof</code> read in. The file <samp>gmon.sum</samp>
  89. may be one of the specified input files; the effect of this is to
  90. merge the data in the other input files into <samp>gmon.sum</samp>.
  91. </p>
  92. <p>Eventually you can run <code>gprof</code> again without &lsquo;<samp>-s</samp>&rsquo; to analyze the
