Get llvm-mca results inside opt?
Hi, I am trying to generate performance models for specific pieces of code like an omp.outlined function. Lets say I have the following code: start_collect_parallel_for_data(-1.0,-1.0,-1.0, size, “tag for this region”); #pragma omp parallel for for(auto i = 0; i < size; ++i){ // … do work } stop_collecting_parallel_for_data(); The omp region will get outlined into a new function and what I

...ce the original code with the new MCA information. Since this solution is not awesome and we may have many functions in a given TU that we care about I was hoping to find a better way. To compute the throughput indicators you would need to implement a logic similar to the one implemented by class SummaryView [3]. Ideally, most of that logic could be factored out into a helper class in order to help your particular use case and possibly avoid code duplication. Thanks, I’ll look into it. I hope it helps, -Andrea [1] https://github.com/llvm-mirror/llvm/blob/master/include/llvm/MCA/InstrBuilder.h [2] htt...
