# ValueType definitions.
# Sources included in both, llvm-min-tblgen and llvm-tblgen, must be included
# into LLVMTableGenBasic to avoid redundant compilation and problems with build
# caches.
# At least one source file must be included directly to avoid CMake problems.
# E.g. CMake derives which linker to use from the types of sources added.
