The most complex part of "The Art of Compiler Design" is optimization. Before generating machine code, the compiler converts the AST into an Intermediate Representation. IR is a low-level, language-independent representation that makes it easier to perform data-flow analysis. Common optimizations include: The journey begins with the Lexical Analyzer, or scanner
