isl is a library for manipulating sets and relations of integer points bounded by linear constraints. Supported operations on sets include intersection, union, set difference, emptiness check, convex hull, (integer) affine hull, integer projection, and computing the lexicographic minimum using parametric integer programming. It also includes an ILP solver based on generalized basis reduction and operations geared towards polyhedral compilation such as dependence analysis, scheduling, and AST generation.
Release Notes: This release fixes some bugs, including some hard-to-trigger bugs and one minor bug which resulted in different code generation output on Solaris.
Release Notes: This release makes the code generation output independent of endianness, allowing the tests to pass on big endian machines.
Release Notes: This version is released under the MIT license and adds support for code generation.
Release Notes: This release brings improved support for multi quasi-affine expressions and fixes various minor bugs.
Release Notes: This release mainly brings improved argument parsing and improved support for parameter sets.
