L属性文法属性求值器的自动生成技术

The Automatic Generation Technique for Evaluator of L-Attributed Grammar

提出一种L属性文法LL（1）属性求值器的自动生成技术.该技术充分利用L属性文法和LL（1）分析方法的特点，节省了属性求值器的存储空间，扩展了语义规则的描述能力．且实现了一本基于该技术的属性求值器自动生成系统．

An autornatic generatlon technique for the evaluators of L-attributed grammars is presented in this paper. This technique has utterly applied the merits of L-attributed grammars and LL (1 ) parsing, extended the describing ability of semantic rtiies, reduced the storage needs for the evaluatorsAn automatic generatlon system has also been developed on the basis of this technique.
