A 解析表 is an essential component in the process of syntax analysis during the compilation of プログラミング言語. It serves as a guide for parsers—specifically, those implementing predictive parsing techniques such as LL(1) and LR(1) parsing. The primary purpose of a parsing table is to provide a set of rules that dictate how the parser should process input tokens based on the current state of the 解析プロセス.
LL解析の文脈では、解析表は通常、行が文法の非終端記号に対応し、列が終端記号（入力トークン）に対応する二次元構造です。表の各セルには、特定の非終端記号が解析スタックのトップにあり、特定の終端記号が入力から読み取られているときに適用すべき生成規則が含まれています。
LR解析のための解析表はより complex, comprising two main components: the action table and the goto table. The action table indicates whether the parser should shift (read a new token), reduce (apply a production rule), accept (indicate successful parsing), or error out. The goto table, on the other hand, directs the parser on transitioning between states based on non-terminal symbols after a reduction has been performed.
Parsing tables are crucial for ensuring that a parser can efficiently and accurately analyze the syntax of a given input according to the rules defined in the grammar. They allow the parser to make decisions without backtracking, thus optimizing the parsing process and improving 全体的な性能.
