The verified C compiler.
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.
