Syntax directed translation scheme pdf


•(Syntax- directed) translation schemes. –A translation scheme is a notation for attaching program fragments to the productions of a grammar. The program fragments are executed when the production is used during syntax analysis. 5. translation from language ⊆ Σ* L i to language ⊆ ∆* L o is a relation Τfrom Σto ∆ such that the domain of Τis L i and the range of is L o. The formalism for specifying translations, SDTS, is basically a grammar in which translation elements are attached to each production: Definition: A syntax-directed translation . Translation Schemes •What we have seen so far is called a “Syntax-directed definition” –Which is simply a specification of the translation to be performed –Without necessarily addressing how this might be accomplished in any real implementation •Order of evaluation of rules is not specified, for example.
