-
-<p>This section describes how to acquire and build llvm-gcc 4.2, which is based
-on the GCC 4.2.1 front-end.  Supported languages are Ada, C, C++, Fortran,
-Objective-C and Objective-C++.  Note that the instructions for building these
-front-ends are completely different (and much easier!) than those for building
-llvm-gcc3 in the past.</p>
-
-<ol>
-  <li><p>Retrieve the appropriate llvm-gcc-4.2-<i>version</i>.source.tar.gz
-         archive from the <a href="http://llvm.org/releases/">LLVM web
-         site</a>.</p>
-
-      <p>It is also possible to download the sources of the llvm-gcc front end
-         from a read-only mirror using subversion.  To check out the 4.2 code
-         for first time use:</p>
-
-<div class="doc_code">
-<pre>
-svn co http://llvm.org/svn/llvm-project/llvm-gcc-4.2/trunk <i>dst-directory</i>
-</pre>
-</div>
-
-      <p>After that, the code can be be updated in the destination directory
-         using:</p>
-
-<div class="doc_code">
-<pre>svn update</pre>
-</div>
-
-      <p>The mirror is brought up to date every evening.</p></li>
-
-  <li>Follow the directions in the top-level <tt>README.LLVM</tt> file for
-      up-to-date instructions on how to build llvm-gcc.  See below for building
-      with support for Ada or Fortran.
-</ol>
-
-</div>
-
-<!-- *********************************************************************** -->
-<h2><a name="ada">Building the Ada front-end</a></h2>
-<!-- *********************************************************************** -->
-
-<div>
-<p>Building with support for Ada amounts to following the directions in the
-top-level <tt>README.LLVM</tt> file, adding ",ada" to EXTRALANGS, for example:
-<tt>EXTRALANGS=,ada</tt></p>
-
-<p>There are some complications however:</p>
-
-<ol>
-  <li><p>The only platform for which the Ada front-end is known to build is
-      32 bit intel x86 running linux.  It is unlikely to build for other
-      systems without some work.</p></li>
-  <li><p>The build requires having a compiler that supports Ada, C and C++.
-      The Ada front-end is written in Ada so an Ada compiler is needed to
-      build it.  Compilers known to work with the
-      <a href="http://llvm.org/releases/download.html">LLVM 2.7 release</a>
-      are <a href="http://gcc.gnu.org/releases.html">gcc-4.2</a> and the
-      2005, 2006 and 2007 versions of the
-      <a href="http://libre.adacore.com/">GNAT GPL Edition</a>.
-      <b>GNAT GPL 2008, gcc-4.3 and later will not work</b>.
-      The LLVM parts of llvm-gcc are written in C++ so a C++ compiler is
-      needed to build them.  The rest of gcc is written in C.
-      Some linux distributions provide a version of gcc that supports all
-      three languages (the Ada part often comes as an add-on package to
-      the rest of gcc).  Otherwise it is possible to combine two versions
-      of gcc, one that supports Ada and C (such as the
-      <a href="http://libre.adacore.com/">2007 GNAT GPL Edition</a>)
-      and another which supports C++, see below.</p></li>
-  <li><p>Because the Ada front-end is experimental, it is wise to build the
-      compiler with checking enabled.  This causes it to run much slower, but
-      helps catch mistakes in the compiler (please report any problems using
-      <a href="http://llvm.org/bugs/">LLVM bugzilla</a>).</p></li>
-  <li><p>The Ada front-end <a href="http://llvm.org/PR2007">fails to
-      bootstrap</a>, due to lack of LLVM support for
-      <tt>setjmp</tt>/<tt>longjmp</tt> style exception handling (used
-      internally by the compiler), so you must specify
-      <tt>--disable-bootstrap</tt>.</p></li>
-</ol>
-
-<p>Supposing appropriate compilers are available, llvm-gcc with Ada support can
-   be built on an x86-32 linux box using the following recipe:</p>
-
-<ol>
-  <li><p>Download the <a href="http://llvm.org/releases/download.html">LLVM source</a>
-      and unpack it:</p>
-
-<pre class="doc_code">
-wget http://llvm.org/releases/2.7/llvm-2.7.tgz
-tar xzf llvm-2.7.tgz
-mv llvm-2.7 llvm
-</pre>
-
-      <p>or <a href="GettingStarted.html#checkout">check out the
-      latest version from subversion</a>:</p>
-
-<pre class="doc_code">svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm</pre>
-
-      </li>
-
-  <li><p>Download the
-      <a href="http://llvm.org/releases/download.html">llvm-gcc-4.2 source</a>
-      and unpack it:</p>
-
-<pre class="doc_code">

-      latest version from subversion</a>:</p>
-

-svn co http://llvm.org/svn/llvm-project/llvm-gcc-4.2/trunk llvm-gcc-4.2
-</pre>
-      </li>
-
-  <li><p>Make a build directory <tt>llvm-objects</tt> for llvm and make it the

-
-<pre class="doc_code">

-
-      <p>If you have a multi-compiler setup and the C++ compiler is not the
-      default, then you can configure like this:</p>
-
-<pre class="doc_code">
-CXX=<b>PATH_TO_C++_COMPILER</b> ../llvm/configure --prefix=<b>/usr/local</b> --enable-optimized --enable-assertions

-

-      The <tt>--enable-checking</tt> flag turns on sanity checks inside the compiler.
-      To turn off these checks (not recommended), replace <tt>--enable-checking</tt>
-      with <tt>--disable-checking</tt>.
-      Additional languages can be appended to the <tt>--enable-languages</tt> switch,
-      for example <tt>--enable-languages=ada,c,c++</tt>.</p>
