[ICE]: RUSTC_LOG=trace broken on main

[khyperia]

Bisected to #156963

Code

# needs `rustup toolchain link stage1 build/host/stage1`
./x build library && RUSTC_LOG=trace rustc +stage1 tests/ui/return/return-nil.rs

(return-nil.rs was chosen because it's an extremely simple file, just any hello-world will presumably do it)

Error output

error: internal compiler error: compiler/rustc_middle/src/query/plumbing.rs:660:5: `tcx.crate_name(LocalCrate)` is not supported for this key;
                                hint: Queries can be either made to the local crate, or the external crate. This error means you tried to use it for one that's not supported.
                                If that's not the case, crate_name was likely never assigned to a provider function.

[khyperia]

the call stack is literally the line where we try to feed the LOCAL_CRATE name (feed.crate_name(crate_name)):

rust/compiler/rustc_interface/src/passes.rs

Lines 1006 to 1008 in 4530eac

	let feed = tcx.create_crate_num(stable_crate_id).unwrap();
	assert_eq!(feed.key(), LOCAL_CRATE);
	feed.crate_name(crate_name);

and then inside feed.crate_name, a few calls inside, this #[instrument] (newly added in the linked PR) tries to log the name of its argument:

rust/compiler/rustc_hir/src/definitions.rs

Lines 255 to 259 in 4530eac

	#[instrument(level = "trace", skip(self), ret)]
	#[inline(always)]
	pub fn def_path_hash(&self, id: LocalDefId) -> DefPathHash {
	DefPathHash::new(self.stable_crate_id, self.def_path_hashes[id])
	}

the ID is something about the local crate, so the debug logging tries to fetch the name of the local crate, which goes kaboom, since the local crate name hasn't finished being fed to the query system yet.

deleting the #[instrument] "fixes" the issue. dunno how important that #[instrument] is, if that's ok as an easy fix, or if we should do something clever to keep it.

[aerooneqq]

Workaround: #[instrument(level = "trace", skip(self, id), fields(def_index=?id.local_def_index), ret)] on def_path_hash instead of #[instrument(level = "trace", skip(self), ret)]
