One deterministic module has affine ranking function unknown-#length-unknown[s] + -1 * s and consists of 3 locations. One deterministic module has affine ranking function -1 * a + unknown-#length-unknown[__builtin_alloca (delim_len)] and consists of 5 locations. One deterministic module has affine ranking function 18446744073709551615 * unknown-#length-unknown[a] + -1 * s and consists of 6 locations. One deterministic module has affine ranking function unknown-#length-unknown[reject] + -1 * i and consists of 5 locations. One nondeterministic module has affine ranking function -1 * a + 18446744073709551615 * unknown-#length-unknown[__builtin_alloca (in_len)] and consists of 10 locations. One nondeterministic module has affine ranking function -2 * i + 3 * unknown-#length-unknown[reject] and consists of 12 locations. One nondeterministic module has affine ranking function 5 * unknown-#length-unknown[reject] + -2 * i and consists of 14 locations. One nondeterministic module has affine ranking function 5 * unknown-#length-unknown[reject] + -2 * i and consists of 13 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[reject] + -1 * reject + -1 * i and consists of 3 locations. 9 modules have a trivial ranking function, the largest among these consists of 59 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 125.3s and 19 iterations.
