One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[arr] and consists of 6 locations. One deterministic module has 2-nested ranking function (if unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] > 0 then 1 else 0), (if unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] > 0 then unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] else -8 * j + 4) and consists of 7 locations. One deterministic module has 2-nested ranking function (if unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] > 0 then 1 else 0), (if unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] > 0 then unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] + -8 * unknown-#memory_int-unknown[arr][arr] else 8 * length + -8 * j) and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.5s and 5 iterations.
