that builds the following additional llvm/clang tools: - bugpoint - llc - lli - llvm-ar - llvm-as - llvm-bcanalyzer - llvm-diff - llvm-dis - llvm-extract - llvm-ld - llvm-link - llvm-mc - llvm-nm - llvm-objdump - llvm-prof - llvm-ranlib - llvm-rtdyld - llvm-stub - macho-dump - opt These tools are mainly useful for people that want to manipulate llvm bitcode (.bc) and llvm assembly language (.ll) files, or want to tinker with llvm and clang themselves.
