Bottom-Up Parsing/Exercise 14: LALR(1)
From Wiki**3
Problema
Consider the following grammar, where A is the initial symbol and { x, y, z } is the set of terminal symbols:
A → M z x | z M x | z x z
M → y | ε
- Compute the set of LALR(1) states for the grammar. Build the corresponding LALR(1) parse table.
- Compact the parse table, eliminating and propagating reductions.
- Show the parsing process for input zyx (including the actions/gotos and the input and stack states). In case of conflict, assume YACC's behavior.
Solução
Na imagem, os conflitos indicados para a regra 2 são para a regra 5.
Note-se que a solução apresentada é para SLR(1) e LALR(1) (a vermelho).
