Does anyone in the industry use it ? Does anyone knows for sure that Airbus uses it ?
> For two decades now, Airbus France has been using our tools in the development of safety-critical avionics software for several airplane types, including the flight control software of the A380, the world’s largest passenger aircraft.

You have to understand that CompCert's main competition in this space was an ancient version of GCC without any optimizations. This is mostly an issue of certification. CompCert got the same certification and is already a great improvement just by virtue of having a register allocator...
A register allocator! :)
I've heard Xavier Leroy say a year or two ago that Airbus was still evaluating CompCert and was thinking of using it in production for the aircraft generation after the next one, or something like that. And that CompCert sales have been very slow in general.

AbsInt has been selling timing analysis tools for decades, and Airbus and the other customers are probably almost exclusively customers for those tools. That doesn't mean that those customers also buy CompCert. It seems like they don't.
