An LR(1) parser is a finite-state automaton, equipped with a stack, which uses a combination of its current state and one lookahead symbol in order to determine which action to perform next. We present a validator which, when applied to a context-free grammar G and an automaton A, checks that A and G agree.
Validating the parser provides the correctness guarantees required by verified compilers and other high-assurance software that involves parsing. The validation ...
Abstract. An LR(1) parser is a finite-state automaton, equipped with a stack, which uses a combination of its current state and one lookahead.
Reject | Accept(v). Barthwal & Norrish proved (in HOL) soundness and completeness for every parser successfully generated by their generator.

Some parser generators accept LL(1), e.g. javacc – less powerful. • Rest of this lecture: how to use parser generators. • Can we use parsers for programs other.
