<a name="dragonegg">DragonEgg: GCC-4.5 as an LLVM frontend</a>
<a name="dragonegg">DragonEgg: llvm-gcc ported to gcc-4.5</a>
</div>
<div class="doc_text">
<p>
The goal of <a href="http://dragonegg.llvm.org/">DragonEgg</a> is to make
gcc-4.5 act like llvm-gcc without requiring any gcc modifications whatsoever.
<a href="http://dragonegg.llvm.org/">DragonEgg</a> is a shared library (dragonegg.so)
that is loaded by gcc at runtime. It ...
<a href="http://dragonegg.llvm.org/">DragonEgg</a> is a port of llvm-gcc to
gcc-4.5. Unlike llvm-gcc, which makes many intrusive changes to the underlying
gcc-4.2 code, dragonegg in theory does not require any gcc-4.5 modifications
whatsoever (currently one small patch is needed). This is thanks to the new
<a href="http://gcc.gnu.org/wiki/plugins">gcc plugin architecture</a>, which
makes it possible to modify the behaviour of gcc at runtime by loading a plugin,
which is nothing more than a dynamic library which conforms to the gcc plugin
interface. DragonEgg is a gcc plugin that causes the LLVM optimizers to be run
instead of the gcc optimizers, and the LLVM code generators instead of the gcc
code generators, just like llvm-gcc. To use it, you add
"-fplugin=path/dragonegg.so" to the gcc-4.5 command line, and gcc-4.5 magically
becomes llvm-gcc-4.5!
</p>
<p>
DragonEgg is still a work in progress. Currently C works very well, while C++,
Ada and Fortran work fairly well. All other languages either don't work at all,
or only work poorly. For the moment only the x86-32 and x86-64 targets are
supported, and only on linux.
</p>
<p>
DragonEgg has not yet been released. Once gcc-4.5 has been released, dragonegg
will probably be released as part of the following LLVM release.
