+# 1. Build lib/System and lib/Support, which are used by utils (tblgen).
+# 2. Build utils, which is used by VMCore.
+# 3. Build VMCore, which builds the Intrinsics.inc file used by libs.
+# 4. Build libs, which are needed by llvm-config.
+# 5. Build llvm-config, which determines inter-lib dependencies for tools.
+# 6. Build tools, runtime, docs.
