Could you clarify what this means, ideally as a comment above the
property?

Thanks,

Oh I see. It’s a problem that ‘tunable?’ in itself doesn’t solve.

The fix would be twofold: (1) remove ‘-march’ and similar compiler
arguments that cause it to generate code that assumes AVX availability,
and (2) add the ‘tune?’ property for those who want a fine-tuned binary.

Could you look into it?

Thanks,
Ludo’.

Umm, it definitely solved it on my machine, which doesn't have AVX.
If that's not a "proper" fix, then sure, I can try looking into it more.
But it seems to me like `tunable?` is already working as intended.

What I meant is that someone installing ‘vice’ without ‘--tune’ will
still get a binary that assumes AVXsomething, which may or may not work
on their machine.

The default binary (without ‘--tune’) should target baseline x86_64.

That’s why we need both fixes I mentioned above.

HTH!
