# Chomsky NF or Greibach NF benefits for LR parser?

Are there any benefits of having grammar in CNF/GNF for LR parser? I have those in mind:

• total speed of creating a parser (that is time for creating CNF/GNF out of the grammar, and then creating action table),
• the size of action/goto table (in total)
• is there any "side-effect" of removing some of shift-reduce conflicts

?

• @greenoldman: Yes, it's fairly simple. But you need to know k in advance, which takes away a lot of the fun. – rici Aug 18 '15 at 23:55
