<h2>DESCRIPTION<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
<p>The <strong class="program">llvm-objdump</strong> utility prints the contents of object files and
final linked images named on the command line. If no file name is specified,
<strong class="program">llvm-objdump</strong> will attempt to read from <em>a.out</em>. If <em>-</em> is used as a
file name, <strong class="program">llvm-objdump</strong> will process a file on its standard input
stream.</p>
