Download the C-to-Isabelle parser used in L4.verified

What am I downloading?

You are downloading a tool and set of theories for Isabelle/HOL. This tool translates a large subset of C99 code into the imperative language Simpl embedded in the theorem prover Isabelle/HOL. This language provides a verified verification condition generator and further tools for software verification.

This tool is used to verify the functional correctness of the seL4 microkernel and some other programs, as part of the L4.verified project.

Where can I get help?

Please send email to c-parser <AT> if you have questions, problems, or feature requests. While we can't promise to be able to provide support and help for all requests, we are interested in turning this tool from a research prototype for experts into a slightly more widely applicable tool.

Where does development take place?

The C parser code is part of the L4.verified repository, in the tools/c-parser directory.
