# LLVMBuild Integration
#
# We use llvm-build to generate all the data required by the CMake based
# build system in one swoop:
#
#  - We generate a file (a CMake fragment) in the object root which contains
#    all the definitions that are required by CMake.
#
#  - We generate the library table used by llvm-config.
#
#  - We generate the dependencies for the CMake fragment, so that we will
#    automatically reconfigure outselves.
