            Bug ID: 38437
           Summary: [llvm-exegesis][llvm-mca] Real vs theoretical code
                    snippet analysis
           Product: new-bugs
           Version: unspecified

        Depends on: 37696, 38048

For a given code snippet, it would be very useful for llvm-exegesis to compare
the actual performance vs llvm-mca's prediction.

This could be driven by code snippets from real code or possibly from a fuzzer
