Rename `rust.use-lld` to `rust.bootstrap-override-lld` #147046

Kobzol · 2025-09-25T21:02:19Z

First part of #146640. The old option is kept for backwards compatibility, we can remove it in ~6 months, as usually.

I'm not sure if the bootstrap prefix is ideal, after all we have a bunch of other configs that only affect bootstrap's behavior and not the built artifacts. Maybe build.override-lld? But I don't think it matters that much, as long as it's clear that it is an override, and how does it differ from rust.lld.

Looks good, I'm on board with the naming. Feel free to r=me after fixing the tidy failure.

Looks like you accidentally forgot to update this. 😅

🤦 I'll update it the next time we modify the change tracker, to avoid churn. Thanks!

In that case I might as well fix it in #146929, assuming another opportunity doesn’t come up first.

Ok, let's do that please 😇 Thanks!
