CompCert qualified for the MFC generation of ATR 42/72 aircraft

Saarbruecken, March 20, 2026 — AbsInt today officially announced that earlier this year the formally verified CompCert compiler was successfully qualified for the Multi-Function Computer New Generation (MFC_NG) of ATR 42 and ATR 72 aircraft.

For the first time, certification credits for compliance with DO-178C, DO-333, and DO-330 have been successfully claimed for critical avionics software from compiler usage.

Claiming certification credits from compiler usage allows applicants to eliminate, reduce, or automate specific objectives defined by DO-178C. The use of CompCert supports the objective of verifying property preservation between source and object code — even in the presence of compiler optimizations.

As a result, test effort can be reduced. For example, formal verification performed at the source-code level can replace certain object-code testing activities otherwise required to demonstrate that the executable code complies with low-level requirements and maintains robustness.

The certification efforts and costs are further reduced by AbsInt’s accompanying Qualification Support Kit — a major advancement in the qualification of compilers for avionics software at the highest assurance levels under DO-178C.

About CompCert

CompCert is the first commercially available optimizing compiler that has been formally verified. The machine code that it generates is mathematically proven to exactly conform to the formal semantics of the source C program. In recognition of its groundbreaking formal proof, CompCert received the 2021 ACM Software System Award.

CompCert supports a wide selection of target architectures, including PowerPC, ARM, x86, RISC-V, and TriCore. It has been successfully deployed in commercial projects for many years, and previously achieved qualification for safety-critical industry applications certified under IEC 60880 and IEC 61508.

By adopting CompCert, customers improve development efficiency and benefit from significant gains in appli­cation performance, while reducing the risk of malfunctions.
