<h2>DESCRIPTION<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
<p>The <strong class="program">llvm-readobj</strong> tool displays low-level format-specific information
about one or more object files.</p>
<p>If <code class="docutils literal notranslate"><span class="pre">input</span></code> is “<code class="docutils literal notranslate"><span class="pre">-</span></code>“, <strong class="program">llvm-readobj</strong> reads from standard
input. Otherwise, it will read from the specified <code class="docutils literal notranslate"><span class="pre">filenames</span></code>.</p>

<h2>DIFFERENCES TO LLVM-READELF<a class="headerlink" href="#differences-to-llvm-readelf" title="Permalink to this headline">¶</a></h2>
<p><strong class="program">llvm-readelf</strong> is an alias for the <em class="manpage"><a class="manpage reference external" href="https://llvm.org/docs/CommandGuide/llvm-readobj.html">llvm-readobj</a></em> tool with a
slightly different command-line interface and output that is GNU compatible.
Following is a list of differences between <strong class="program">llvm-readelf</strong> and
<strong class="program">llvm-readobj</strong>:</p>
<ul class="simple">
<li><p><strong class="program">llvm-readelf</strong> uses <cite>GNU</cite> for the <a class="reference internal" href="#cmdoption-llvm-readobj-elf-output-style"><code class="xref std std-option docutils literal notranslate"><span class="pre">--elf-output-style</span></code></a> option
by default. <strong class="program">llvm-readobj</strong> uses <cite>LLVM</cite>.</p></li>
<li><p><strong class="program">llvm-readelf</strong> allows single-letter grouped flags (e.g.
<code class="docutils literal notranslate"><span class="pre">llvm-readelf</span> <span class="pre">-SW</span></code> is the same as <code class="docutils literal notranslate"><span class="pre">llvm-readelf</span> <span class="pre">-S</span> <span class="pre">-W</span></code>).
<strong class="program">llvm-readobj</strong> does not allow grouping.</p></li>
<li><p><strong class="program">llvm-readelf</strong> provides <a class="reference internal" href="#cmdoption-llvm-readobj-symbols"><code class="xref std std-option docutils literal notranslate"><span class="pre">-s</span></code></a> as an alias for
<a class="reference internal" href="#cmdoption-llvm-readobj-symbols"><code class="xref std std-option docutils literal notranslate"><span class="pre">--symbols</span></code></a>, for GNU <strong class="program">readelf</strong> compatibility, whereas it is
an alias for <a class="reference internal" href="#cmdoption-llvm-readobj-sections"><code class="xref std std-option docutils literal notranslate"><span class="pre">--section-headers</span></code></a> in <strong class="program">llvm-readobj</strong>.</p></li>
<li><p><strong class="program">llvm-readobj</strong> provides <code class="docutils literal notranslate"><span class="pre">-t</span></code> as an alias for <a class="reference internal" href="#cmdoption-llvm-readobj-symbols"><code class="xref std std-option docutils literal notranslate"><span class="pre">--symbols</span></code></a>.
<strong class="program">llvm-readelf</strong> does not.</p></li>
<li><p><strong class="program">llvm-readobj</strong> provides <code class="docutils literal notranslate"><span class="pre">--sr</span></code>, <code class="docutils literal notranslate"><span class="pre">--sd</span></code>, <code class="docutils literal notranslate"><span class="pre">--st</span></code> and <code class="docutils literal notranslate"><span class="pre">--dt</span></code> as
aliases for <a class="reference internal" href="#cmdoption-llvm-readobj-section-relocations"><code class="xref std std-option docutils literal notranslate"><span class="pre">--section-relocations</span></code></a>, <a class="reference internal" href="#cmdoption-llvm-readobj-section-data"><code class="xref std std-option docutils literal notranslate"><span class="pre">--section-data</span></code></a>,
<a class="reference internal" href="#cmdoption-llvm-readobj-section-symbols"><code class="xref std std-option docutils literal notranslate"><span class="pre">--section-symbols</span></code></a> and <a class="reference internal" href="#cmdoption-llvm-readobj-dyn-symbols"><code class="xref std std-option docutils literal notranslate"><span class="pre">--dyn-symbols</span></code></a> respectively.
<strong class="program">llvm-readelf</strong> does not provide these aliases, to avoid conflicting
with grouped flags.</p></li>
