Prepare the `bootstrap` tool for the new check-cfg syntax #116983

Urgau · 2023-10-20T16:02:04Z

This PR prepare the bootstrap tool for the new check-cfg syntax as well as the according changes to Cargo.

Note that while the new syntax can technically available on stage > 2, we actually cannot use it since we need a cargo version that supports the new syntax which won't happen until the next beta bump (if I understand everything correctly).

r? bootstrap

Hit this issue #117000 (comment). How can we help this moving forward?

This PR shouldn't be necessary until the next beta bump. Something unexpected is going on.

I've added a commit to enable the new {-Z,--}check-cfg arguments when doing a "local rebuild" (build the same version of rustc with it-self) and also added a revert commit of #117018 since it's no longer necessary.

Overall result: ❌ regressions - no action needed

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

I tried a few configurations locally and they were all working.

Hopefully, this will fix bootstrap timings on perf.RLO, so we should do that as soon as possible. Let's merge it and see if anything else breaks.

I wonder if this should be also gated for local rebuilds, but I don't think we can even set a custom rustdoc in config.toml, so it probably doesn't matter.
