<b>Duncan needs to write me</b>.
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.
DragonEgg is a shared library (llvm.so) that is loaded by gcc at runtime. It
uses the new gcc plugin architecture to disable the GCC optimizers and code
generators, and schedule the LLVM optimizers and code generators (or direct
output of LLVM IR) instead. Currently only Linux and Darwin are supported,
and only on x86-32 and x86-64. It should be easy to add additional unix-like
architectures and other processor families. Since gcc-4.5 has not yet been
released, neither has <a href="http://dragonegg.llvm.org/">DragonEgg</a>.
To build <a href="http://dragonegg.llvm.org/">DragonEgg</a> you will need to
check out the development versions of <a href="http://gcc.gnu.org/svn.html/">
gcc</a>, <a href="http://llvm.org/docs/GettingStarted.html#checkout">llvm</a>
and <a href="http://dragonegg.llvm.org/">DragonEgg</a> from their respective
subversion repositories.
