From the first character of source text to the final machine instruction, Compilers and Language Design follows the whole compilation pipeline in one continuous story. It starts with lexical analysis and grammar theory, then works through LL and LR parsing, type systems and Hindley-Milner inference, intermediate representations, and SSA form. From there it covers data-flow analysis, classical and loop optimisations, instruction selection, register allocation, and runtime systems with garbage collection.The book treats language design as an engineering discipline. Every parsing technique, type rule and optimisation is weighed for what it costs and what it buys. It's a clear, practical guide for developers, students and language enthusiasts who want to understand how compilers work and why languages are designed the way they are.
