Sep 16, 2014 15-411: Compiler Design. Andre Platzer?, with edits by Frank Pfenning place. The job of the lexical analysis is also to classify input tokens into types like. INTEGER or IDENTIFIER or . token of type REAL has been recognized and that the remaining input is -3+x;if. We also want to know what the value of

Consider grammar: stmt if expr then stmt. | if expr then stmt else stmt. | ? expr term relop term. | term term id. | num. With regular definitions: if if then then.
Why Separating. Lexical and Syntactic? • Simplicity of design. • Improved compiler efficiency. – allows us to use specialized technique for lexer, not suitable for parser Token classes. • One token per keyword. • Tokens for the operators. • One token representing all identifiers. • Tokens representing constants (e.g. numbers).
