Abstract: Jourdan and others presented a method to formally verify a parser in their paper Validating LR(1) Parsers published in 2012,and successfully applied it to the parser verification of CompCert compiler(version 2.3 and above).With this method,formal validation of the Lustre* parser is completed,which is a part of the Open L2C project,and one of the two options of the front-end parser of the Open L2C compiler is implemented.Firstly,this paper discussesthe implementation of the parser,inclu- ding some valuable technical details.Thenit analyzes the running performance and correctness of the parser.And finally,how to apply this method tomore general parsersis summarized.

Key words: CompCert, Coq, Formal verification, LR(1) parser, Lustre* language, Syntax parsing
