It is a * NULL-terminated linked list of relations. Each relation is described * using a matrix where each row represents a linear constraint. The entries * of each row are organised in the following order: * - An equality/inequality tag: 0 means the row corresponds to an * equality constraint == 0, 1 means it is an inequality >= 0. * - The coefficients of the output dimensions. * - The coefficients of the input dimensions (0 for a set). * - The coefficients of the local (existentially quantified) dimensions. * - The coefficients of the parameters. * - The coefficient of the constant. * Thus we have the following invariant: nb_columns = * 1 + nb_output_dims + nb_input_dims + dims + nb_parameters + 1. * Moreover we use the following conventions: * - Sets (e.g., iteration domains) are the images of relations with a * zero-dimensional domain, hence the number of input dimensions is 0. * - The first output dimension of any access relations corresponds to * the name of the array. * The type field may provide some semantics about the relation, it may be: * - Undefined : OSL_UNDEFINED, * - An iteration domain : OSL_TYPE_DOMAIN, * - A scattering relation : OSL_TYPE_SCATTERING, * - An access relation : OSL_TYPE_ACCESS. */ struct osl_relation { int type;
