CompCert is a formally verified C compiler whose correctness is machine-checked with the Coq proof assistant, guaranteeing generated assembly matches the source C semantics. It targets ARM, PowerPC, RISC-V, and x86 processors and is used in safety-critical embedded software.

Use cases

• compile safety-critical C code with a verified compiler
• rule out miscompilation bugs in avionics or medical software
• research formally verified compilation
• teach compiler correctness with Coq proofs
• build DO-178C qualified toolchains for critical embedded software

When to choose

• you need high-assurance compilation for certified or safety-critical embedded software
• you want a compiler backed by machine-checked correctness proofs
• your target is ARM, PowerPC, RISC-V, or x86 and you use ISO C 2011

When to avoid

• you need a fully free/open-source license for commercial use
• you rely on C features outside CompCert's supported subset
• you need broad platform or ecosystem support like GCC or Clang
