This issue will only be triggered if you build with "-DCMAKE_INSTALL_PREFIX:PATH=/sw/opt/llvm-4.0" to place llvm in a buried subdirectory and access the compilers with symlinks in /sw/bin pointing at the actual compilers in /sw/opt/llvm-4.0/bin. The call to llvm::sys::path::parent_path(D.getInstalledDir()) incorrectly places the install level at /sw instead of the actual sw/opt/llvm-4.0.
