...checking in ScopDetection, then we can detect the kernel loop as a valid scop and gain significant performance improvement. I tried to follow your hints to look into the executeScopConditionally() in CodeGen/Utils.cpp, but I cannot fully understand how to affect ScopDetection pass by modifying the executionScopConditionally(). Do you mean I can add ISL checking information into the Context in executionScopConditionally()? Could you give some more concrete ideas? Is there any code examples about ISL alias analysis?

Hi all, It seems that Polly's code generation can leads to high compile-time overhead, especially for PolyBench applications such as 2mm, 3mm, gemm, syrk, etc. Some basic evaluation and analysis for Polly's code generation can be referred to http://llvm.org/bugs/show_bug.cgi?id=16898. Currently, we can choose to run -polly-code-generator=cloog or -polly-code-generator=isl for code
