<h2>DESCRIPTION<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
<p><strong class="program">llvm-link</strong> takes several LLVM bitcode files and links them together
into a single LLVM bitcode file. It writes the output file to standard output,
unless the <a class="reference internal" href="opt.html#cmdoption-o"><code class="xref std std-option docutils literal notranslate"><span class="pre">-o</span></code></a> option is used to specify a filename.</p>
