Similar names ignore underscore prefixed names
changelog: Ignore underscore-prefixed names for similar_names
IMO, this lint is not very helpful for underscore-prefixed variables. Usually they are unused or are just there to ignore part of a destructuring.
`manual_filter_map` and `manual_find_map`
changelog: Add `manual_filter_map` and replace `find_map` with `manual_find_map`
Replaces #6453Fixes#3188Fixes#4193
~Depends on #6567 (to fix an internal lint false positive)~
This replaces `filter_map` and `find_map` with `manual_filter_map` and `manual_find_map` respectively. However, `filter_map` is left in place since it is used for a variety of other cases. See discussion in #6453.
Following traits are now diagnostic items:
- `From` (unchanged)
- `Into`
- `TryFrom`
- `TryInto`
This also adds symbols for those items:
- `into_trait`
- `try_from_trait`
- `try_into_trait`
Gracefully handle loop labels missing leading `'` in different positions
Fix#81192.
* Account for labels when suggesting `loop` instead of `while true`
* Suggest `'a` when given `a` only when appropriate
* Add loop head span to hir
* Tweak error for invalid `break expr`
* Add more misspelled label tests
* Avoid emitting redundant "unused label" lint
* Parse loop labels missing a leading `'`
Each commit can be reviewed in isolation.
Fix formatting for removed lints
- Don't add backticks for the reason a lint was removed. This is almost
never a code block, and when it is the backticks should be in the reason
itself.
- Don't assume clippy is the only tool that needs to be checked for
backwards compatibility
I split this out of https://github.com/rust-lang/rust/pull/80527/ because it kept causing tests to fail, and it's a good change to have anyway.

Doc markdown
I added "WebGL" along the lines of the existing "OpenGL" to the whitelist of `doc_markdown` as I found this to be a pretty common term.
(this is a follow-up of the now closed https://github.com/rust-lang/rust-clippy/pull/6388)
changelog: Whitelist "WebGL" in `doc_markdown`.
Fix false positive in write_literal and print_literal (numeric literals)
changelog: No longer lint numeric literals in [`write_literal`] and [`print_literal`].
Fixes#6335
Fix the reversed suggestion message of `stable_sort_primitive`.
Now Clippy emits `stable_sort_primitive` warning as follows:
```
warning: used sort instead of sort_unstable to sort primitive type `usize`
--> src\asm.rs:41:13
|
41 | self.successors.sort();
| ^^^^^^^^^^^^^^^^^^^^^^ help: try: `self.successors.sort_unstable()`
|
= note: `#[warn(clippy::stable_sort_primitive)]` on by default
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#stable_sort_primitive
```
I think the position of `sort` and `sort_unstable` in the first line should be reversed.
changelog: Fix the reversed suggestion message of `stable_sort_primitive`.
Fixes#81007
Previously, we would fail to collect tokens in the proper place when
only builtin attributes were present. As a result, we would end up with
attribute tokens in the collected `TokenStream`, leading to duplication
when we attempted to prepend the attributes from the AST node.
We now explicitly track when token collection must be performed due to
nomterminal parsing.
Fix path_to_res for enum inherent items
changelog: none
I tried to add `Option::is_some` to the paths but got a false positive from the invalid paths lint. Turns out the `path_to_res` function does not find inherent impls for enums. I fixed this and took the liberty to do some additional cleanup in the method.
Add new lint `upper_case_acronyms`
Close#1335
I need some reviews on the English sentences because I feel they're messed up. ;)
changelog: Add new lint `upper_case_acronyms`
size_of_in_element_count: Disable lint on division by byte-size
Fixes#6511
It is fairly common to divide some length in bytes by the byte-size of a single element before creating a `from_raw_parts` slice or similar operation. This lint would erroneously disallow such expressions.
Just in case, instead of simply disabling this lint in the RHS of a division, keep track of the inversion and enable it again on recursive division.
