One deterministic module has affine ranking function -1 * i + in_len and consists of 5 locations. One deterministic module has affine ranking function out_len + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * s2 + unknown-#length-unknown[__builtin_alloca (in_len)] and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.7s and 7 iterations. TraceHistogramMax:1. Analysis of lassos took 8.6s. Construction of modules took 0.1s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 6. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 27 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 24 states and ocurred in iteration 5. Nontrivial modules had stage [3, 0, 0, 0, 0].
