Re: [isabelle] Verification of C Programs

Maybe a bit more background on that:

Our C-Parser at will translate a large subset of C into the Isabelle/Simpl language,  which comes with various semantics formalisations, verification condition generator, etc.

The version on the website above runs on Isabelle2009-1, we should be able to release the Isabelle2011-1 version shortly, and we're working on the Isabelle2012 update.

The Simpl language is described in Norbert Schirmer's PhD thesis. The C memory model in Harvey Tuch's thesis and a few papers from our web site.

Although the language subset and tool chain are quite powerful and have been applied to large verifications, it is not a very polished tool set at moment, definitely more on the research software side. We'd be happy to help with questions, though.
