  32 <p>This section describes how to aquire and build llvm-gcc4, which is based on
  33 the GCC 4.0.1 front-end.  This front-end supports C, C++, Objective-C, and
  34 Objective-C++.  Note that the instructions for building this front-end are
  35 completely different (and much easier!) than those for building llvm-gcc3 in
  36 the past.</p>
  37
  38 <ol>
  39   <li><p>Retrieve the appropriate llvm-gcc4-x.y.source.tar.gz archive from the
  40          <a href="http://llvm.org/releases/">llvm web site</a>.</p>
  41
  42       <p>It is also possible to download the sources of the llvm-gcc4 front end
  43          from a read-only mirror using subversion.  To check out the code the
  44          first time use:</p>
  45
  46 <div class="doc_code">
  47 <pre>
  48 svn co svn://anonsvn.opensource.apple.com/svn/llvm/trunk <i>dst-directory</i>
  49 </pre>
  50 </div>
  51
  52       <p>After that, the code can be be updated in the destination directory
  53          using:</p>
  54
  55 <div class="doc_code">
  56 <pre>svn update</pre>
  57 </div>
  58
  59       <p>The mirror is brought up to date every evening.</p></li>
  60
  61   <li>Follow the directions in the top-level <tt>README.LLVM</tt> file for
  62       up-to-date instructions on how to build llvm-gcc4.</li>
