Hi all,

Does anyone know if there is available a complete grammar for Ada 2012, lets say, in Flex+Bison or similar compiler construction tool-chain? 

I would like to extend it to some new contract constructs, but writing a complete parser is a huge (and extremely time-consuming) task that I would like to avoid :).

Thanks in advance,
David
