bootstrap: fix a comment
I don't actually know if this is right, though... but "a single call to `paths` will only ever generate a single call to `paths`" just does not make sense.
Fix some comments related to upvars handling
I'm tidying up my ergonomic ref counting PR and I'm going to make some small, simple and unrelated changes outside that PR, so the main PR sticks more straight to the point.
rustc_borrowck: Suggest changing `&raw const` to `&raw mut` if applicable
Closes#127562
For reference, here is the diff compared to the original error reported in that issue before #134244 stopped suggesting the invalid syntax:

Use links to edition guide for edition migrations
This switches the migration lints for the 2024 edition to point to the edition guide documentation instead of the tracking issues. I expect the documentation should be easier to understand for a user, compared to most of the issues which don't have any direct information, and can be a bit confusing to navigate, or have outdated information.
Rename `rustc_mir_build::build` to `builder`
GitHub's “Go to file” feature silently ignores all files in this module, presumably because they are in a directory named `build`, which is mistaken for a build-output directory. That makes it meaningfully harder to view those files and their history via GitHub.
This PR sidesteps that issue by renaming `build` to `builder`, which in context has basically the same meaning, but can't be mistaken for a build-output directory.
---
Extracted from #133404, after #133592 changed the .gitignore rule from `build/` to `/build`. The problem of GitHub ignoring these files still exists even after that change, which suggests that GitHub's behaviour is a hard-coded heuristic that isn't influenced by the repository's git settings.
Currently this PR doesn't include the tidy rule forbidding `build` as a module name, but that could be added if people think it's a good idea.
Handle fndef rendering together with signature rendering
Pulled out of https://github.com/rust-lang/rust/pull/134353
Changes some highlighting in type mismatch errors around fndefs
Remove queries from the driver interface
All uses of driver queries in the public api of rustc_driver have been removed in https://github.com/rust-lang/rust/pull/134130 already. This removes driver queries from rustc_interface and does a couple of cleanups around TyCtxt construction and entering enabled by this removal.
Finishes the removal of driver queries started with https://github.com/rust-lang/rust/pull/126834.
In #129533 the main hash function changed and the order of `-Z
input-stats` output changed, which showed that it is dependent on the
hash function, even though it is sorted. That's because entries with the
same cumulative size are ordered in a way that depends on the hash
function.
This commit fixes that by using the entry label as the secondary
ordering key.
`CheckAttrVisitor::check_doc_keyword` checks `#[doc(keyword = "..")]`
attributes to ensure they are on an empty module, and that the value is
a non-empty identifier.
The `rustc::existing_doc_keyword` lint checks these attributes to ensure
that the value is the name of a keyword.
It's silly to have two different checking mechanisms for these
attributes. This commit does the following.
- Changes `check_doc_keyword` to check that the value is the name of a
keyword (avoiding the need for the identifier check, which removes a
dependency on `rustc_lexer`).
- Removes the lint.
- Updates tests accordingly.
There is one hack: the `SelfTy` FIXME case used to used to be handled by
disabling the lint, but now is handled with a special case in
`is_doc_keyword`. That hack will go away if/when the FIXME is fixed.

`@rustbot` modify labels: rollup
Since the previos commit renamed `assignment_rhs_span` to just
`rhs_span` there is no need for a variable just to shorten the
expression on the next line. Inline the variable.
Some trait method vs impl method signature difference diagnostic cleanups

Check for array lengths that aren't actually `usize`
I wish typeck wouldn't give us `ty::Array`s that have this problem in the first place, but we can check for it.

reject unsound toggling of RISCV target features
~~Stacked on top of https://github.com/rust-lang/rust/pull/133417, only the last commit is new.~~
Works towards https://github.com/rust-lang/rust/issues/132618 (but more [remains to be done](https://github.com/rust-lang/rust/pull/134337#issuecomment-2544228958))
Part of https://github.com/rust-lang/rust/issues/116344
Cc ``@beetrees`` I hope I got everything. I didn't do anything about "The f and zfinx features are incompatible" and that's not an ABI thing (right?) and I am not sure how to handle it with these ABI checks.
r? ``@workingjubilee``
Ideally we'd also reject target specs that disable the `f` feature but set an ABI that requires `f`... but I don't want to duplicate this logic. I have some ideas for how maybe the entire float ABI check logic should be different, now that we have some examples of what these ABI checks look like, but that will be a future PR.
Keep track of patterns that could have introduced a binding, but didn't
When we recover from a pattern parse error, or a pattern uses `..`, we keep track of that and affect resolution error for missing bindings that could have been provided by that pattern. We differentiate between `..` and parse recovery. We silence resolution errors likely caused by the pattern parse error.

rustdoc-search: handle `impl Into<X>` better
This PR fixes two bugs I ran into while searching the compiler docs:
- It omitted an `impl Trait` entry in the type signature field, producing `TyCtxt, , Symbol -> bool`
- It didn't let me search for `TyCtxt, DefId, Symbol -> bool` even though that's a perfectly good description of the function I was looking for (the function actually used `impl Into<DefId>`

Correctly handle comments in attributes in doctests source code
Fixes https://github.com/rust-lang/rust/issues/134221.
The problem was that attributes are "inlined" (backlines are stripped), then when there is an inline comment inside it, the attribute is never considered valid (since unclosed). Fix was to simply put back backlines in case it's a multiline attribute.

rustc_mir_build: Clarify that 'mirrored' does not mean 'flipped' or 'reversed'
My intuition for 'mirrored' is that it means 'flipped' or 'reversed'. Clarify that that is not what is meant to 'mirror' the THIR from the HIR.
