This article describes the formal verification of a compilation algorithm that transforms parallel moves (parallel assignments between variables) into a semanticallyequivalent sequence of elementary moves. Two different specifications of the algorithm are given: an inductive specification and a functional one, each with its correctness proofs. A functional program can then be extracted and integrated in the Compcert verified compiler. Keywords Parallel move
