I just stumbled across this article about micro-architecture-specific
optimisations in ARM:
https://www.phoronix.com/news/ARM64-Linux-No-Uarch-Opts
They briefly mention x86_64, and I agree it's good to avoid
micro-architecture-specific optimisations and now it makes me wonder
where the line is drawn, like the recent introduction of the optimizer
hint regarding LEA instructions being slow on some middle-aged CPUs.
