# Top-Level LLVM Build Stages:
#   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.
#
# When cross-compiling, there are some things (tablegen) that need to
# be build for the build system first.

# If "RC_ProjectName" exists in the environment, and its value is
# "llvmCore", then this is an "Apple-style" build; search for
# "Apple-style" in the comments for more info.  Anything else is a
# normal build.
