this caused a lot of noise because benchmarks and tests were also checked

before:
./x.py clippy |& wc -l
74026

with change:
./x.py clippy |& wc -l
43269

Hmm, this makes it so it's no longer possible to pass --all-targets to clippy - is that intentional? I agree it doesn't seem super useful, but it seems weird to remove the option altogether ... although I guess you can still add it back with CARGOFLAGS=--all-targets.

Also, for this step specifically it should just be an early return above, because we've already run on the standard library; this invocation is only for the other targets. The other steps are correct though.

How did that work previously? When I check ./x.py clippy --all-targets pre-branch, I just get a

Unrecognized option: 'all-targets'

Usage: x.py <subcommand> [options] [<paths>...]

error...

I think at least a comment as to why this isn't being specified is a good idea. We can consider the defaults (or ability to provide it) later.

@matthiaskrgr did you miss https://github.com/rust-lang/rust/pull/88511/files#r698829310 ?

Ah yes, I missed that.
I excluded an early return to run() of Std, I hope that's what you ment`:

        if builder.kind != Kind::Clippy {
            return;
        }

@matthiaskrgr I meant here: https://github.com/rust-lang/rust/blob/e7c15b95174e5bc78b51a7887ac9e6db3468d65b/src/bootstrap/check.rs#L114

The idea is to avoid running cargo twice, not to skip it altogether.

(or in other words, your "handled elsewhere" comment is incorrect)

Oh sorry, didn't realize this was waiting on me. Could you switch the labels next time?
