Optimization diagnostics have been part of LLVM for years. While important, these diagnostics had a narrow focus on providing user feedback on the success or failure of Auto-vectorization. This work explores the possibility of extending on this foundation in order to build up a full-fledged performance analysis tool set using the compiler. The talk will first lay out the elements of this tool set. Then we will evaluate and refine it through an exploration of real- world use cases.
