If a region does not have more than one loop, we do not identify it as a Scop in ScopDetection. The main optimizations Polly is currently performing (tiling, preparation for outer-loop vectorization and loop fusion) are unlikely to have a positive impact on individual loops. In some cases, Polly's run-time alias checks or conditional hoisting may still have a positive impact, but those are mostly enabling transformations which LLVM already performs for individual loops. As we do not focus on individual loops, we leave them untouched to not introduce compile time regressions and execution time noise. This results in good compile time reduction (oourafft: -73.99%, smg2000: -56.25%).
