+<div name="langs" class="answer">
+ <p>LLVM currently has full support for C and C++ source languages. These are
+ available through a special version of GCC that LLVM calls the
+ <a href="#cfe">C Front End</a></p>
+ <p>There is an incomplete version of a Java front end available in the
+ <tt>llvm-java</tt> CVS repository. There is no documentation on this yet so
+ you'll need to download the code, compile it, and try it.</p>
+ <p>In the <tt>examples/BFtoLLVM</tt> directory is a translator for the
+ BrainF*** language (2002 Language Specification).</p>
+ <p>In the <tt>projects/Stacker</tt> directory is a compiler and runtime
+ library for the Stacker language, a "toy" language loosely based on
Forth.</p>
+ <p>The PyPy developers are working on integrating LLVM into the PyPy backend
+ so that PyPy language can translate to LLVM.</p>
+</div>
+<div name="langhlsupp" class="question">
+ <p>What support is there for a higher level source language constructs for
+ building a compiler?</p>
+</div>
+<div class="answer">
+ <p>Currently, there isn't much. LLVM supports an intermediate representation
+ which is useful for code representation but will not support the high level
+ (abstract syntax tree) representation needed by most compilers. There are no
+ facilities for lexical nor semantica analysis. There is, however, a <i>mostly
+ implemented</i> configuration-driven
+ <a href="CompilerDriver.html">compiler driver</a> which simplifies the task
+ of running optimizations, linking, and executable generation.</p>
+ <p>You might be interested in following the progress of the <a
+ href="http://hlvm.org";>HLVM Project</a> which is attempting to address
these
+ issues.</p>
