WebBuilding Predictive Parsing Tables The following algorithm can be used to construct a predictive Parser Table (PT) for a language L(G) defined by a grammar G. • BPPT1. For each production A → of the grammar G, do steps 2 and 3. • BPPT2. For each terminal a in the FIRST( ), add to PT[A,a]. • BPPT3. WebNon-recursive predictive parsing Observation: Our recursive descent parser encodes state information in its run-time stack, or call stack. Using recursive procedure calls to implement a stack abstraction may not be particularly efficient. This suggests other implementation methods: •explicit stack, hand-coded parser •stack-based, table ...
