The llvm-tablegen then converts these target descriptor .td fies into enums, which can be used in program logic such as frame lowering, instruction selection, instruction printing, and so on. More detailed and complex architectures like ARM and X86 can give insight on a detailed description of the target.

In the first chapter, we tried a basic exercise to get hands-on with various tools provided by the LLVM infrastructure. In the subsequent chapters, that is, Chapter 2, Building LLVM ...
