LINGUIST-86

Abstract
LINGUIST-86 is a commercially-developed translator-writing-system based on attribute grammars [K]. From an input attribute grammar it generates a set of high-level language source modules that form an alternating-pass attribute evaluator [JW]. LINGUIST-86 generates attribute evaluators efficient enough to run on a microcomputer at speeds competitive with other translators on the system. The Attributed Program Tree is kept on secondary storage rather than in randomly-accessed memory, thus allowing non-trivial inputs to be evaluated on a microcomputer system. LINGUIST-86 also applies an optimization called static subsumption that eliminates many copy rules from the generated evaluators. LINGUIST-86 is itself written as an 1800 line attribute grammar and is self-generating.
