...ending upon it not burden or bloat the runtime libraries unnecessarily. All of these options seem... moderately painful.

...3.2 and passes with clang 3.3. Using a fixed version allows you to build all clang/llvm/compiler-rt with one compiler. It simplifies the build process quite a bit. Also better for isolating regressions in compiler-rt, especially if you use git-bisect.

Just in case - do we want to link with libz.so installed in the system, or be self-contained and copy sources to LLVM repo?

...pcoming 3.3) instead of tip-of-the-trunk clang? It looks like everything works great, but that you just need to make those UB tests 'unsupported' since they fail with "libclang_rt.ubsan was built without __int128 support".
