The article explores the process of building a toy compiler using Go and LLVM. It begins by introducing LLVM, a compiler framework and collection of tools that can be used to build programming languages. The author explains the components of a typical compiler design, including the frontend, optimizer, and backend. They highlight the advantage of this modular design, which allows for the reuse of different parts of the compiler for different programming languages. The article then delves into LLVM IR, a low-level intermediate representation used by the LLVM compiler framework. The author explains the structure of LLVM IR and its static single assignment form. They also mention the availability of great APIs in different programming languages for working with LLVM. Overall, this article provides a comprehensive overview of building a toy compiler with Go and LLVM, making it a valuable resource for developers interested in compiler development.
