Hi, see
http://www.antlr.org/blog/antlr3/codegen.tml
for a write-up on new DFA implementation; should be able to do in a
few months. The problem is highlighted by the following:
In the Mantra language parser there are about 700 lines out of 8726
of class definitions for DFA states. In the lexer there were 2051
lines out of 5670. There are about 400 .class files in the directory
just for DFA states (from 1 parser and 3 tree parsers). Ick.
