[antlr-interest] Parser generation takes hours

I'm currently rewriting a LR parser to be used for ANTLR. As a result,
ANTLR works literaly for hours before it outputs errors about my grammar.
My work is not finished; I have removed all left-recursions but I still
have to do left-factorisations. The problem being that since ANTLR works
for hours before I get the errors, it isn't very practical for me to fix
Do you have any suggestions in this case? What could be done so that
ANTLR would take only dozen of minutes? Is there something capital that
I missed about ANTLR and LL grammars? How should be written ANTLR rules
to avoid such a problem?
Thanks in advance, any adice will be welcome.
