45 /* The Polyhedron structure comes directly from PolyLib (defined in
46 * polylib/types.h) here is how it looks like (at least in PolyLib 5.20.0
49 * typedef struct polyhedron {
50 * unsigned Dimension, // Dimension number (NbColumns-2 in Matrix).
51 * NbConstraints, // Number of constraints (NbRows in Matrix).
52 * NbRays, // Number of rays in dual representation.
53 * NbEq, // Number of vertices (?).
54 * NbBid; // Number of extremal rays (?).
55 * Value **Constraint; // The pointers to rows in matrix representation.
56 * Value **Ray; // The pointers to rays in dual representation.
57 * Value *p_Init; // The whole data, consecutive in memory.
58 * int p_Init_size; // To clear values in GMP mode.
59 * struct polyhedron *next; // Pointer to next component of the union.
65 * CloogDomain structure:
66 * this structure contains a polyhedron in the PolyLib shape and the number of
67 * active references to this structure. Because CLooG uses many copies of
68 * domains there is no need to actually copy these domains but just to return
69 * a pointer to them and to increment the number of active references. Each time
70 * a CloogDomain will be freed, we will decrement the active reference counter
71 * and actually free it if its value is zero.
