Hmm, maybe r? @camelid? The changes are all fairly simple, there's just a lot of them 😅 sorry for all the work |

Left an initial review on some parts (haven't yet reviewed some of the files with massive changes like clean/mod.rs
).
There were several places with statements like let cx = self.cx;
or let tcx = self.cx.tcx
and changes from cx.sess()
to cx.tcx.sess
. I'm assuming these changes are necessary to please the borrow-checker?

Is this collect
being added because otherwise there were borrowck errors?

Yes, otherwise self.cx
is used both here and inside the filter_map
closure at the same time (auto_traits
borrows from cx
and .clean(cx)
requires unique access to the reference).
Yes.

Well, these were certainly necessary (#82020 (comment)):
but these may have been extraneous:
I'll go through the changes again and see if I can revert them. |

This seems like a behavior change.

It's not actually - it's just that the predicate is folded above (in clean_where_predicates
) instead of here. It looks confusing because you're only looking at 2 commits, not the full diff.

Much so, yes. That would be a good follow up pr, but I didn't want to do it here because it's already +-300. |
Yeah, I might try doing it after this PR if that's okay with you :) |

What do you think of undoing the move to free functions? It's probably better overall to use free functions, but it makes reviewing the diffs a lot harder. I used the |

Yikes, that is an intimidating error!
Sure, sounds fine :) |

Seems like a bug in the toolstate program. cc @rust-lang/infra |
Also, it seems surprising that Miri no longer builds after this PR. The only rustc change shouldn't affect Miri and should be backwards-compatible. |
I left some of them so this change doesn't balloon in size and because removing the RefCell in `DocContext.resolver` would require compiler changes. Thanks to `@jyn514` for making this a lot easier with rust-lang#82020!

This combined with #82018 should hopefully help with #82014 by allowing
cx.cache.exported_traits
to be modified inregister_res
. Previously it had to use interior mutability, which required either adding a RefCell tocache.exported_traits
on top of the existingRefCell<Cache>
or mixing reads and writes betweencx.exported_traits
andcx.cache.exported_traits
. I don't currently have that working but I expect it to be reasonably easy to add after this.
