The function cloog_union_domain_from_isl_union_map takes a isl_union_map as input and returns a pointer to a CloogUnionDomain. The input is a mapping from different spaces (different tuple names and possibly different dimensions) to a common space. The iteration domains are set to the domains in each space. The statement names are set to the names of the spaces. The parameter names of the result are set to those of the input, but the iterator and scattering dimension names are left unspecified. The function consumes a reference to the given isl_union_map. The function cloog_union_domain_from_isl_set is similar, but takes an unscattered domain as input. It is not defined for an union_set, because the order of iterations from two different isl_sets is undefined, if no scattering is provided.
