Sample text

FIRST(γ) is the set of terminals that can begin strings derived from γ. • FOLLOW(X) is the set of terminals that can immediately follow X. That is, t ∈ FOLLOW(X) if there is any derivation containing Xt. This can occur if the derivation contains X Y Zt where Y and Z both derive ∊. A precise definition of FIRST, FOLLOW, and nullable is that they are the smallest sets for which these properties hold: For each terminal symbol Z, FIRST[Z] = {Z}. 13 for computing FIRST, FOLLOW, and nullable just follows from these facts; we simply replace each equation with an assignment statement, and iterate.

LR PARSING OF AMBIGUOUS GRAMMARS Many programming languages have grammar rules such as • • • S → if E then S else S S → if E then S S → other which allow programs such as if a then if b then s1 else s2 Such a program could be understood in two ways: (1) (2) if a then { if b then s1 else s2 } if a then { if b then s1 } else s2 In most programming languages, an else must match the most recent possible then, so interpretation (1) is correct.

But we will need something more powerful than finite automata to parse languages described by grammars. In fact, grammars can also be used to describe the structure of lexical tokens, although regular expressions are adequate - and more concise - for that purpose. 1 CONTEXT-FREE GRAMMARS As before, we say that a language is a set of strings; each string is a finite sequence of symbols taken from a finite alphabet. For parsing, the strings are source programs, the symbols are lexical tokens, and the alphabet is the set of token-types returned by the lexical analyzer.
