> Like, I should be able to give the compiler a hot loop and a week, and see what it can come up with. There are optimization libraries which can find the optimum combination of parameters for an objective, like Optuna. It would be enough to expose all the optimization knobs that LLVM has, and Optuna will find the optimum for a particular piece of code on a particular test payload.
