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#
20# When cross-compiling, there are some things (tablegen) that need to
21# be build for the build system first.
22
23# If "RC_ProjectName" exists in the environment, and its value is
24# "llvmCore", then this is an "Apple-style" build; search for
25# "Apple-style" in the comments for more info.  Anything else is a
26# normal build.
