Our evaluation show that when compiled with "clang -Xclang -load -Xclang LLVMPolly.so -mllvm -polly -mllvm -polly-optimizer=none -mllvm -polly-code-generator=none", the

Hello all, I have done some basic experiments about Polly canonicalization passes and I found the SCEV canonicalization has significant impact on both compile-time and execution-time performance. Detailed results for SCEV and default canonicalization can be viewed on: http://188.40.87.11:8000/db_default/v4/nts/32 (or 33, 34) *pNoGen with SCEV canonicalization (run 32): -O3 -Xclang -load

Hello all, I have evaluated the compile-time and execution-time performance of Polly canonicalization passes. Details can be referred to http://188.40.87.11:8000/db_default/v4/nts/recent_activity. There are four runs: pollyBasic (run 45): clang -O3 -Xclang -load -Xclang LLVMPolly.so pollyNoGenSCEV (run 44): clang -O3 -Xclang -load -Xclang LLVMPolly.so -mllvm -polly -mllvm -polly-codegen-scev

Hi, polly is run very early and schedules the following passes before it runs: /// @brief Schedule a set of canonicalization passes to prepare for Polly /// /// The set of optimization passes was partially taken/copied from the /// set of default optimization passes in LLVM. It is used to bring the code /// into a canonical form that simplifies the analysis and optimization passes /// of Polly.
