This problem has partly been addressed in at least two articles:


J. Heering, P. Klint, and J. Rekers
Incremental generation of parsers
IEEE Transactions on Software Engeneering, 16(12):1344-1351, 1990


R.N. Horspool
Incremental generation of LR parsers
Computer Languages, 15(4):205-233, 1990


How to update an LR parse table _during_ parsing without disturbing the current
parse is an open problem.
