Chapter 3. Advanced LLVM IR
LLVM provides a powerful intermediate representation for efficient compiler transformations and analysis, while providing a natural means to debug and visualize the transformations. The IR is so designed that it can be easily mapped to high level languages. LLVM IR provides typed information, which can be used for various optimizations.
In the last chapter, you learned how to create some simple LLVM instructions within a function and module. Starting from simple examples such as emitting binary operations, we constructed functions in a module and also created some complex programming paradigms such as if-else and loops. LLVM provides a rich set of instructions and intrinsics to emit a complex IR.
In this chapter, we will ...
