- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 2 terminating modules (0 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length * sizeof(char))] + -1 * s and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[d] + -1 * d and consists of 3 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 20.6s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 20.0s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s.
