  12 # Top-Level LLVM Build Stages:
  13 #   1. Build lib/Support and lib/TableGen, which are used by utils (tblgen).
  14 #   2. Build utils, which is used by IR.
  15 #   3. Build IR, which builds the Intrinsics.inc file used by libs.
  16 #   4. Build libs, which are needed by llvm-config.
  17 #   5. Build llvm-config, which determines inter-lib dependencies for tools.
  18 #   6. Build tools, docs, and cmake modules.
  19 #

  21 # be build for the build system first.
