My First Language Front End with LLVM Tutorial (llvm.org)

A new tutorial titled “My First Language Frontend with LLVM” has been released, aimed at those familiar with C++ but lacking compiler experience. Over the course of several chapters, it guides users in building a simple language called "Kaleidoscope." The tutorial emphasizes practical application by incrementally developing features such as a lexer, parser, abstract syntax tree (AST), and code generation to LLVM Intermediate Representation (IR), eventually adding support for JIT compilation and object file generation. This resource is significant for the AI/ML community as it demystifies compiler construction and showcases the powerful capabilities of LLVM in performance-oriented code generation. By adopting a hands-on approach, the tutorial encourages experimentation and creativity, serving as an accessible entry point for developers interested in language design and compiler theory. Key technical aspects include parsing techniques, control flow management, user-defined operators, and integration of debugging tools, all within a manageable codebase. This initiative underscores the utility of LLVM as a preferred platform for building high-performance applications in AI and beyond.
