Compiler Construction

Build your own programming language. Master Lexing, Parsing, ASTs, and Code Generation using LLVM to understand how code runs.

Compilers are the ultimate meta-programming. This course guides you through building a real programming language from scratch. You will learn to tokenize source code (Lexing), define grammars and build Abstract Syntax Trees (Parsing), and perform Semantic Analysis. We cover Code Generation targeting LLVM IR (Intermediate Representation), allowing your language to compile to native machine code. You will gain a profound understanding of how high-level code maps to hardware.
