Design of a Certifying Compiler Supporting Proof of Program Safety

Safety is an important property of high-assurance software, and one of the hot research topics on it is the verification method for software to meet its safety policies. In our previous work, we designed a pointer logic system and proposed a framework for developing and verifying safetycritical programs. And in this paper, we present the design and implementation of a certifying compiler based on that framework. Here we will mainly explain verification condition generation, generation of code and assertions, and proof generation for basic blocks. Our certifying compiler has the following novelties: 1) it supports a programming language equipped with both a type system and a logic system; 2) and it can produce safety proofs for programs with pointers.
