摘要

A method which allows an efficient combination of LR parsing and attributeevaluation for an arbitrary L attributed LR grammar is presented. Each attribute is evaluated during parsing as soon as possible, and the evaluation is completed before parsing of the input string is finished. Without imposing any restrictions on the attribute dependencies in a given L attributed grammar, this strategy results in an optimal compromise between the usual one pass and two pass attribute evaluation schemes for L attributed grammars.
