WebAug 25, 2010 · It isn't hard to find backtracking LR parsers, or use Bison's GLR option, which in effect have infinite lookahead. At that point, Bison is strictly more powerful than ANTLR, in that ANTLR cannot handle left recursive rules and Bision (LR parsers) can do this just fine. – Ira Baxter Aug 27, 2010 at 7:49 Add a comment Your Answer WebOct 27, 2024 · Yes, this is true for ANTLR, YACC/Bison, and all other similar parsers. Semantic analysis of the parse tree (or AST for others), in combination with a symbol table, is the responsibility of the developer. For the actual rendering of the IR, use ANTLR's companion library StringTemplate. – GRosenberg Oct 27, 2024 at 23:38
