CHANGES: Goblint "lean" release after a lot of cleanup. * Remove unmaintained analyses: OSEK, ARINC, shapes, containment, deadlocksByRaces (goblint/analyzer#460, goblint/analyzer#736, goblint/analyzer#812, goblint/analyzer#474). * Add interactive analysis (goblint/analyzer#391). * Add server mode (goblint/analyzer#522). * Add Compilation Database support (goblint/analyzer#406, goblint/analyzer#448). * Add floating point domain, unrolled array domain and improved struct domains (goblint/analyzer#734, goblint/analyzer#761, goblint/analyzer#577, goblint/analyzer#419). * Add static loop unrolling and heap variable unrolling (goblint/analyzer#563, goblint/analyzer#722). * Improve race detection with may-happen-in-parallel analysis (goblint/analyzer#529, goblint/analyzer#518, goblint/analyzer#595). * Reimplement lockset and deadlock analyses (goblint/analyzer#659, goblint/analyzer#662, goblint/analyzer#650, goblint/analyzer#655). * Add pthread extraction to Promela (goblint/analyzer#220). * Add location spans to output (goblint/analyzer#428, goblint/analyzer#449). * Improve race reporting (goblint/analyzer#550, goblint/analyzer#551). * Improve dead code reporting (goblint/analyzer#94, goblint/analyzer#353, goblint/analyzer#785). * Refactor warnings (goblint/analyzer#55, goblint/analyzer#783). * Add JSON schema for configuration (goblint/analyzer#476, goblint/analyzer#499). * Refactor option names (goblint/analyzer#28, goblint/analyzer#192, goblint/analyzer#516, goblint/analyzer#675). * Add bash completion (goblint/analyzer#669). * Add OCaml 4.13 and 4.14 support, remove OCaml 4.09 support (goblint/analyzer#503, goblint/analyzer#672).

Implementation of the unrolling array domain
Third abstract array domain in use.
FlagConfiguredArrayDomainwill now choose between one of three array domains (PartitionedWithLength,TrivialWithLengthandUnroll) depending on the value ofexp.arrays-domain.When
unrollis chosen,exp.array-unrolling-factorneed to be set as well. The array representation will then consist of a tuple (xl, xr).A new module
ProdListwas add inlattice.mlto help with thexlpart of the unroll domain.All uses and references to
ana.base.partition-arrays.enabledhave been substituted byexp.arrays-domain= "partitioned".Tests for this domain have also been added under tests/regression/54-unroll_arrays
This is the second part of a precision optimization. Displaying the first
kiterations of the array more precisely, will help increase the precision in some cases. Specially if used together with loop unrolling.
