Hi,

> Is it possible to express a logic function returning an array in ACSL?

No it is not possible, unfortunately. The ACSL-By-Example <https://www.cs.umd.edu/class/spring2016/cmsc838G/frama-c/ACSL-by-Example-12.1.0.pdf> document illustrate how to write logic predicates in ACSL dealing with C-arrays, but without manipulating Â« logic Â» arrays directly.
Moreover, let me recall that SMS solvers usually deals with infinite arrays, which is probably not what you want to deal with. So you might need to design a theory of finite arrays first.
