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 VMCore.
15 # 3. Build VMCore, 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, runtime, docs.
20 # When cross-compiling, there are some things (tablegen) that need to
21 # be build for the build system first.
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
27 ifneq ($(findstring llvmCore, $(RC_ProjectName)),llvmCore) # Normal build (not "Apple-style").
