  1. Review for the Midterm. • Overview (Chapter 1): • What are the phases in a compiler? • What do we do in each phase?

  2. Review for the Midterm. • Lexical analyzer (chapter 3): • Regular expression definition • Use regular expression to express an pattern • How to recognize regular expression? • NFA • DFA • minimize the DFA

  3. Review for the Midterm. • Syntax analysis (chapter 4) • context free grammar • use it to specify a language • top-down parsing • LL(1) (What is an LL(1) grammar?) • How an LL(1) parser works? • How to construct an LL(1) parsing table for a grammar. • (First, Follow) • Bottom parsing • SLR, LR(1), LALR • How an LR(1) parser works • How to construct an SLR/LR(1)/LALR(1) parsing table? • What are the major differences among these parsers?
