similar to: [GSoC 2016] Polly as an Analysis pass - Midterm report

Hello, I need to analyze dependencies in my llvm ir by using polly. i created a new pass called mypass there i added polly dependency analysis pass but when i execute this pass in gdb i get no data. Why is that so? My code is follows; namespace { struct mypass : public FunctionPass { static char ID; mypass() : FunctionPass(ID) { } virtual bool runOnFunction(Function &F) {

I have modified the code as follows; now i am using both scopdetection and scopinformation before dependency check but i think link is missing... virtual bool runOnFunction(Function &F) { std::unique_ptr<ScopInfo> Result; std::unique_ptr<ScopDetection> Result2; //polly::ScopDetection pl; auto &LI = getAnalysis<LoopInfoWrapperPass>().getLoopInfo(); auto

HI Hameeza, what do mean by link is still missing? Currently it is not possible to use polyhedral information from within in-tree LLVM passes. This is because Polly is not currently part of the LLVM tree, and is only linked into the tools as an external project. I.e., you can't depend on Polly passes in an in-tree pass. What you can do, though, is use Polly from an out-of-tree context. If

How do you compile the code? Within the Polly subdirectory using CMake? How do you run your pass. Using "opt -mypass inputfile.ll"?

Thank You. Actually i pass polly canonaclize IR to my new created polly pass called "mypass". Mypass should first detect scops then find depedndencies as the mechanism conventional approach. Now i know how to write llvm pass here i am writing pass as loadable module first afterwards i will integrate it with opt in the end. I tried writing following code. Could you please help me on
