One deterministic module has affine ranking function -2 * s1 + 3 * unknown-#length-unknown[__builtin_alloca (file_len)] and consists of 7 locations. One deterministic module has affine ranking function unknown-#length-unknown[s1] + -1 * s1 and consists of 3 locations. One deterministic module has affine ranking function -1 * s2 + unknown-#length-unknown[__builtin_alloca (dir_len+file_len+2)] and consists of 6 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (dir_len+file_len+2)] + -1 * t and consists of 4 locations. One deterministic module has affine ranking function -1 * s1 + unknown-#length-unknown[__builtin_alloca (dir_len+file_len+2)] and consists of 8 locations. 4 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.5s and 10 iterations.
