...SCEVAddRecExpr pollyDependence (run id = 26): Polly with both ScopInfo patch r187728 and PollyDependence patch r187981 that simplify the Read/Write/MayWrite before feeding them into ISL. As a result, I compare pollyDependence (run id = 26) with pollyScopInfo (run id = 25) to see the impact of our ScopDependence patch r187981.  Their only difference is the ScopDependence patch file. Of course, you can view the total performance improvements of ScopInfo patch and PollyDependence patch on:       http://188.40.87.11:8000/db_default/v4/nts/26?compare_to=18&baseline=18 > >The numbers rather sugg...

Their only difference is the ScopDependence patch file. I see. I did not realize that all those runs have been performed with '-O3 -polly'. Now it makes sense. If you happen to not use the tester machine right now, it would be interesting to schedule runs that give u...

...3 Here is the performance comparison for the newest Polly:     http://188.40.87.11:8000/db_default/v4/nts/31?compare_to=18&baseline=18 Overall, there are 198 benchmarks improved and 16 benchmarks regressed. Especially, with those recent performance-oriented patch files for ScopDetect/ScopInfo/ScopDependences/..., we have significantly reduced the compile-time overhead of Polly for a large number of benchmarks, such as:     SingleSource/Benchmarks/Misc/salsa20        -97.84%     SingleSource/Benchmarks/Polybench/linear-algebra/solvers/lu/lu        -85.01%     MultiSource/Applications/obsequi/Obseq...
