Compiler Theory Assignment 1 January 22, 2019 Finite State Machine for Lexical Analysis 1. Make a list of all the tokens found in Atto-C. You may for now treat all keywonds and identifiers as one type of token, call it IDENT. Don’t forget whitespace and comments! 2. Draw a Finite State Machine diagram for recognizing

Compiler Theory Assignment 6, February 7 Parsing with Context-Free Grammars Reading: Chapter 4 of the text. Finite state machines and regular expressions cannot parse all the languages we want; they can only handle “regular” languages. In particular, they cannot count arbitrary numbers; they cannot match parentheses to arbitrary depth. Therefore, we need a more powerful
