Could one use -mtune to optimize to newer hardware, but make sure it runs for older hardware?

- thedance 7y agoMaybe, but unless you actually own the old hardware, why would you? By the way mtune is much less effective than march. It might change the way a few instructions are scheduled but march will use the actual instructions and registers on your machine.
