Explore the process of building a domain-specific language compiler using LLVM in this 36-minute conference talk from YOW! 2016. Discover how LLVM's extensive compiler API and high-performance backends enable the creation of a language that combines C++ performance with the uniqueness of Tolkien's lesser-known Elvish dialects. Learn from Anglo-Danish programmer Erik Corry as he demonstrates how to leverage LLVM's capabilities to develop a custom compiler for your own programming language. Gain insights into software architecture, continuous delivery, and modern software engineering practices that can enhance your compiler development skills.
