CompCert

The verified C compiler.

Overview

The CompCert C verified compiler is a compiler for a large subset of the C programming language that generates code for the PowerPC, ARM, x86 and RISC-V processors.

The distinguishing feature of CompCert is that it has been formally verified using the Coq proof assistant: the generated assembly code is formally guaranteed to behave as prescribed by the semantics of the source C code.

For more information on CompCert (supported platforms, supported C features, installation instructions, using the compiler, etc), please refer to the Web site and especially the user's manual.
