For the previous step take a look at #4.
Our transformation pass is almost complete. In the previous step we have shown how to update the dominator tree to reflect the LLVM IR changes the transformation did. In this step we introduce an example of how to use the LLVM OptimizationRemarksEmitter (ORE) to report the result of the simple analysis done in step2 (candidate selection) and the result of the transformation. We also use the LLVM statistic services to report the number of loops that were transformed by our pass.
