LL(1) Table Driven Parser In a NonRecursive predictive parser, recursion is simulated through a semantic stack, parsing is guided by a predictive table. In order to create this table, you should review the concepts of First and Follow Sets: First Set represents the lookaheads that predict a ...
I'v calculated all the first sets of each production according to https://cs.wmich.edu/~gupta/teaching/cs4850/sumII06/The%20syntax%20of%20C%20in%20Backus-Naur%20form.htm, but I found the first sets is highly conflicted. For example, code like this: static int test () {} | the...
将带有量词的歧义语法转换为LL(1)语法的方法是通过消除左递归和提取左公因子来消除歧义。以下是具体步骤: 1. 消除左递归:对于每个产生式A -> Aα | β,其中α和β是任意符号串,将其转换为A...
LL(1) grammars have the conceptual and practical advantage that they allow the compiler writer to view the grammar as a program; this allows a more natural positioning of semantic actions and a simple attribute mechanism. Resulting parsers can be constructed that do fully automatic error recovery,...
This seem to work to generate a C pseudo-code for the parser:void A() { switch (token) { case 'a' : next(); X(); break; } } void X() { switch (token) { case 'e' : finish(); break; case 'a' : A(); break; case 'b' : B(); X(); break; } } void B() { ...
