ECLR-attributed grammar

ECLR-attributed grammar

ECLR-attributed grammars are a special type of attribute grammars. They are a variant of LR-attributed grammars where an equivalence relation on inherited attributes is used to optimize attribute evaluation. EC stands for equivalence class. Rie is based on ECLR-attributed grammars. They are a superset of LR-attributed grammars.
