The LLLR parser can be constructed for any LR grammar.The LLLR parser produces the left parse of the input string without backtracking.The canonical LL or the LALL parser can be used as the backbone parser.Small canonical or LALR parsers are used for LL ...
The relative merits of LL and LR parsing methods are compared, particular reference being made to ALGOL 68. The fact that LR methods can be applied to a wider class of languages does not seem to give them a significant advantage in practice.
Despite the advances made by modern parsing strategies such as PEG, LL(*), GLR, and GLL, parsing is not a solved problem. Existing approaches suffer from a number of weaknesses, including difficulties supporting side-effecting embedded actions, slow and/...
