...de some suggestions or hints on this problem? OK. I think in this case the problem is actually to figure out why Polly does not give a speedup in terms of execution time, because we have seen large speedups for 2mm and 3mm. Here is what I see: 2mm$ polly-clang 2mm.c -O3 -I ../../../utilities/ -DPOLYBENCH_TIME -DPOLYBENCH_USE_SCALAR_LB -mllvm -polly-ignore-aliasing 2mm$ time ./a.out 18.217128 real 0m18.256s user 0m18.128s sys 0m0.064s 2mm$ polly-clang 2mm.c -O3 -I ../../../utilities/ -DPOLYBENCH_TIME -DPOLYBENCH_USE_SCALAR_LB -mllvm -polly-ignore-aliasing -mllvm -polly 2mm$ time ./a.out 4.986877 real...

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
