Interpretation and reduction of attribute grammars [PDF]
Acta Informatica, 1983 An attribute grammar (AG) is in reduced form if in all its derivation trees every attribute contributes to the translation. We prove that, eventhough AG are generally not in reduced form, they can be reduced, i.e., put into reduced form, without ...
