[antlr-interest] NoViableAltException

[Liviu U]

Hi all,

I built a simplistic C# parser that ignores statements blocks and handles
only declarations. The target output language is C#.
When I parse a moderate size file 500K ( the atnlr parser output ;) ) it
takes 5 seconds and a lot of NoViableAltException are raised and handled by
the parser.
The parsing is successfull, but as we know, exception raising in .NET comes
with a big cost. I think there is a big performance hit in using Exceptions
to handle failures instead of old Winapi style return codes.
Is anything that can be done about it?
