Its official manual says it was originally written to solve code generation problems for optimizing compilers based on the polytope model. ### Project history The README records the first version of that file in January 2002, and the Texinfo manual records its first version in July 2002 with a 1.0 release on September 17, 2002. The manual names Cedric Bastoul as author and describes CLooG as part of the Chunky project for data locality improvement. CLooG's core technical role is polyhedral code generation: given affine constraints and context, it emits pseudo-code or near-compilable code that visits integral points efficiently while avoiding unnecessary control overhead. ### Adoption history The manual says CLooG was used beyond optimizing compilers, including control automata for high-level synthesis and polynomial approximation, and was designed to serve as a back end for automatic parallelizers such as LooPo. The supplied input shows packaging in Homebrew, dnf, and MacPorts. The official README and build docs also describe classic Unix source distribution concerns: configure, make, make install, GMP, PolyLib, and isl backends. ### How it is used Users run cloog, optionally with an input file, or call CLooG as a library. The README describes input as affine inequalities over polyhedra and context parameters, and output as scanning code such as nested loops. Build-time usage is typical autotools C: from Git, fetch submodules and run autogen.sh, then configure, make, and make install. The README documents options for isl, PolyLib, GMP, integer size, and installation prefix. ### Why package nerds care CLooG matters to compiler-package maintainers because it is a small specialized C library in the polyhedral optimization stack, with optional and historical dependencies such as isl, PolyLib, and GMP. Its packaging exposes the intersection of research compiler tooling and Unix library build systems. The changelog shows evolution around isl and OpenScop support, including OpenScop input in 0.17.0 and OpenScop coordinate/loop extensions in later 0.18.x releases. That makes it a useful marker package for polyhedral-model toolchains. ### Timeline - 2001: Manual title page includes a September 2001 origin note. - 2002: README first version recorded in January; manual first version recorded in July; release 1.0 recorded on September 17. - 2004: Manual asks users to cite Bastoul's PACT paper on code generation in the polyhedral model. - 2005: Manual records release 2.0 on November 21. - 2007: Manual records release 2.1 on October 15. - 2011: Changelog records 0.17.0 with OpenScop input support and isl backend updates. - 2012: Changelog records 0.18.0 with isl 0.11.1, OpenMP/vectorization annotations, and OpenSCoP coordinates extension. - 2014: Changelog records 0.18.3 with isl 0.14 and OpenScop loop extension support. - 2015: Manual edition 2.1.2 updated July 27, 2015. ### Related projects - Related projects and dependencies include Chunky, PolyLib, isl, GMP, OpenScop, and LooPo.
