[help-3dldf] Bison parser for machine-like language

[Laurence Finston]

Hello,

I'm starting to think about writing a second scanner/parser for GNU 3DLDF
for fast-loading binary format files in a machine-like language.

Does anybody have any experience using Bison for parsing such languages,
and/or does anybody know of any free software (preferably GNU software)
that uses Bison to implement such a language?  Any pointers would be much
appreciated.

Thanks,

Laurence Finston
