In the spirit of the famous CLI stack project  the Verisoft project  aims at the pervasive verification of entire computer systems including hardware, system software, compiler, and communicating applications, with a special focus on industrial applications. The main programming language used in the Verisoft project is C0 (a subset of C which is similar to MISRA C ). This paper reports on (i) an operational small steps semantics for C0 which is formalized in Isabelle/HOL , (ii) the formal specification of a compiler from C0 to the DLX machine language [14, 23] in Isabelle/HOL, (iii) a paper and pencil correctness proof for this compiler and the status of the formal verification effort for this proof, and (iv) the implementation of the compiler in C0 and a formal proof in Isabelle/HOL that the implementation produces the same code as the specification.
