Semantics

The unroll construct unrolls the outermost loop of the loop nest according to its speciﬁed clause. If no clauses are speciﬁed, if and how the loop is unrolled is implementation deﬁned. The unroll construct results in a generated loop that has canonical loop nest form if and only if the partial clause is speciﬁed.
