You don't need compiler-rt, and even if you did want to try to use it you'd probably need to compile it manually b/c it would need to be cross-compiled.

One problem that you'll have is that the base system compiler is too old to compile LLVM. When I last built on the BG/P, I used the following command line:

make CXX=/soft/apps/fen/gcc-4.4.3/bin/g++ ENABLE_OPTIMIZED=1 \
EXTRA_OPTIONS='-m64 -UPPC -fno-strict-aliasing -mminimal-toc' \
EXTRA_LD_OPTIONS=-Wl,-rpath=/soft/apps/fen/gcc-4.4.3/lib64

What version of gcc were you trying to use?

For the most part that is correct. There have not been many PPC32 improvements upstream since then. You will want future updates for frontend improvements, and I'll have rebased patches out soon.
