isl: isl (Integer Set Library) isl: isl: isl is a thread-safe C library for manipulating sets and relations isl: of integer points bounded by affine constraints. The descriptions of isl: the sets and relations may involve both parameters and existentially isl: quantified variables. All computations are performed in exact integer isl: arithmetic using GMP. isl: isl: Homepage: http://isl.gforge.inria.fr isl: isl:
