I want to use llvm inside OpenJDK's runtime hotspot for which a variant
exists that uses llvm as a JIT compiler backend. Unfortunately the
outstanding issues of the ARM backend in llvm make it crash often and
not suitable for any real work.

Some details here:

I am maintaining a so-called build recipe for the OpenEmbedded project.
LLVM is cross-compiled in this build environment. I have also filed some
PRs against llvm in order to fix the most pressing issues with the new
cmake based build system. As it looks now most of these things are fixed
now and I am looking forward to need no special patches any more when
llvm 2.6 is released.

No idea about this.
