Fix `await_holding_lock` not linting `parking_lot` Mutex/RwLock
This adds tests for `RwLock` and `parking_lot::{Mutex, RwLock}`, which were added before in 2dc8c083f5, but never tested in UI tests. I noticed this while reading [fasterthanli.me](https://fasterthanli.me/articles/a-rust-match-made-in-hell) latest blog post, complaining that Clippy doesn't catch this for `parking_lot`. (Too many people read his blog, he's too powerful)

- Adds a test for #6446
- Improves the lint message

Don't lint `needless_borrow` in method receiver positions
fixes#8408fixes#8407fixes#8391fixes#8367fixes#8380
This is a temporary fix for `needless_borrow`. The proper fix is included in #8355.
This should probably be merged into rustc before beta branches on Friday. This issue has been reported six or seven times in the past couple of weeks.
changelog: Fix various issues with `needless_borrow` n´. Note to changelog writer: those issues might have been introduced in this release cycle, so this might not matter in the changelog.
Don't lint Default::default if it is the udpate syntax base
changelog: Don't lint `Default::default` it is part of the update syntax
Current clippy warns about this:
```
warning: calling `Foo::default()` is more clear than this expression
--> src/main.rs:12:11
|
12 | ..Default::default()
| ^^^^^^^^^^^^^^^^^^ help: try: `Foo::default()`

```
With these changes, it will not lint that particular expression anymore.
The to_string_in_display lint is renamed to recursive_format_impl
A check is added for the use of self formatted with Display or Debug

format_in_format_args lint
For now only Display and Debug are checked
This could also be extended to other Format traits (Binary, etc.)

Support `cargo dev bless` for tests with revisions
changelog: internal: Support `cargo dev bless` for tests with revisions
Previously bless wouldn't pick up the saved stderr from `target/debug/tests/manual_assert.stage-id.edition2021.stderr` or `target/debug/tests/manual_assert.stage-id.edition2018.stderr` due to there being multiple revisions of the test output
This tweaks compile-test so the built files end up in e.g. `target/debug/tests/ui`, `target/debug/tests/ui-cargo` rather than share the `tests` dir. `cargo dev bless` then uses that to update all the `.stdout/stdout/fixed` files it can find
Also removes an empty file I found, and the logic to remove empty outputs as compiletest doesn't produce empty `.stdout/stderr` files
Add lint `transmute_undefined_repr`
Partially implements #3999 and #546
This doesn't consider `enum`s at all right now as those are going to be a pain to deal with. This also allows `#[repr(Rust)]` structs with only one non-zero sized fields. I think those are technically undefined when transmuted.

r? `@camsteffen` (again, sorry 😛) for the `FormatArgsExpn` change

Fix underflow in `manual_split_once` lint
Hi, a friend found clippy started crashing on a suspiciously large allocation of `u64::MAX` memory on their code.
The mostly minimized repro is:
```rust
fn _f01(title: &str) -> Option<()> {
let _ = title[1..].splitn(2, '[').next()?;
Some(())
}
```
The underflow happens in this case on line 57 of the patch but I've changed the other substraction to saturating as well since it could potentially cause the same issue.
I'm not sure where to put a regression test, or if it's even worth for such a thing.
Aside, has it been considered before to build clippy with overflow checks enabled?

Check usages in `ptr_arg`
fixes#214fixes#1981fixes#3381fixes#6406fixes#6964
This does not take into account the return type of the function currently, so `(&Vec<_>) -> &Vec<_>` functions may still be false positives.
The name given for the type also has to match the real type name, so `type Foo = Vec<u32>` won't trigger the lint, but `type Vec = Vec<u32>` will. I'm not sure if this is the best way to handle this, or if a note about the actual type should be added instead.
changelog: Check if the argument is used in a way which requires the original type in `ptr_arg`
changelog: Lint mutable references in `ptr_arg`
This commit changes the behavior of `single_match` lint.
After that, we won't lint non-exhaustive matches like this:
```rust
match Some(v) {
Some(a) => println!("${:?}", a),
None => {},
}
```
The rationale is that, because the type of `a` could be changed, so the
user can get non-exhaustive match after applying the suggested lint (see
https://github.com/rust-lang/rust-clippy/issues/8282#issuecomment-1013566068
for context).
We also will lint `match` constructions with tuples. When we see the
tuples on the both arms, we will check them both at the same time, and
if they form exhaustive match, we could display the warning.

This pull request adds a lint against single character lifetime names, as they might not divulge enough information about the purpose of the lifetime. This can make code harder to understand. I placed this in `restriction` rather than `pedantic` (as suggested in #8233) since most of the Rust ecosystem already uses single character lifetime names (to my knowledge, at least) and since single character lifetime names aren't incorrect. I'd be happy to change this upon request, however. Fixes#8233.

New macro utils
changelog: none
Sorry, this is a big one. A lot of interrelated changes and I wanted to put the new utils to use to make sure they are somewhat battle-tested. We may want to divide some of the lint-specific refactoring commits into batches for smaller reviewing tasks. I could also split into more PRs.
Introduces a bunch of new utils at `clippy_utils::macros::...`. Please read through the docs and give any feedback! I'm happy to introduce `MacroCall` and various functions to retrieve an instance. It feels like the missing puzzle piece. I'm also introducing `ExpnId` from rustc as "useful for Clippy too". `@rust-lang/clippy`
Fixes#7843 by not parsing every node of macro implementations, at least the major offenders.
I probably want to get rid of `is_expn_of` at some point.

wrong_self_convention: Match `SelfKind::No` more restrictively
The `wrong_self_convention` lint uses a `SelfKind` type to decide
whether a method has the right kind of "self" for its name, or whether
the kind of "self" it has makes its name confusable for a method in
a common trait. One possibility is `SelfKind::No`, which is supposed
to mean "No `self`".
Previously, SelfKind::No matched everything _except_ Self, including
references to Self. This patch changes it to match Self, &Self, &mut
Self, Box<Self>, and so on.
For example, this kind of method was allowed before:
```
impl S {
// Should trigger the lint, because
// "methods called `is_*` usually take `self` by reference or no `self`"
fn is_foo(&mut self) -> bool { todo!() }
}
```
But since SelfKind::No matched "&mut self", no lint was triggered
(see #8142).
With this patch, the code above now gives a lint as expected.

changelog: [`unused_io_amount`]: Improve help text
Clippy helpfully warns about code like this, telling you that you
probably meant "write_all":
fn say_hi<W:Write>(w: &mut W) {
w.write(b"hello").unwrap();
}
This patch attempts to extend the lint so it also covers this
case:
async fn say_hi<W:AsyncWrite>(w: &mut W) {
w.write(b"hello").await.unwrap();
}
(I've run into this second case several times in my own programming,
and so have my coworkers, so unless we're especially accident-prone
in this area, it's probably worth addressing?)
This patch covers the Async{Read,Write}Ext traits in futures-rs,
and in tokio, since both are quite widely used.

Fix `enum_variants` FP on prefixes that are not camel-case
closes#8090
Fix FP on `enum_variants` when prefixes are only a substring of a camel-case word. Also adds some util helpers on `str_utils` to help parsing camel-case strings.
This changes how the lint behaves:
1. previously if the Prefix is only a length of 1, it's going to get ignored, i.e. these were previously ignored and now is warned
```rust
enum Foo {
cFoo,
cBar,
cBaz,
}
enum Something {
CCall,
CCreate,
CCryogenize,
}
```
2. non-ascii characters that doesn't have casing will not be split,
```rust
enum NonCaps {
PrefixXXX,
PrefixTea,
PrefixCake,
}
```
will be considered as `PrefixXXX`, `Prefix`, `Prefix`, so this won't lint as opposed to fired previously.

Fix `SAFETY` comment tag casing in undocumented_unsafe_blocks
This changes the lint introduced in #7748 to suggest adding a `SAFETY` comment instead of a `Safety` comment.
Searching for `// Safety:` in rust-lang/rust yields 67 results while `// SAFETY:` yields 1072.
I think it's safe to say that this comment tag is written in upper case, just like `TODO`, `FIXME` and so on are. As such I would expect this lint to follow the official convention as well.
Note that I intentionally introduced some casing diversity in `tests/ui/undocumented_unsafe_blocks.rs` to test more cases than just `Safety:`.

Implement let-else type annotations natively
Tracking issue: #87335Fixes#89688, fixes#89807, edit: fixes #89960 as well
As explained in https://github.com/rust-lang/rust/issues/89688#issuecomment-940405082, the previous desugaring moved the let-else scrutinee into a dummy variable, which meant if you wanted to refer to it again in the else block, it had moved.
This introduces a new hir type, ~~`hir::LetExpr`~~ `hir::Let`, which takes over all the fields of `hir::ExprKind::Let(...)` and adds an optional type annotation. The `hir::Let` is then treated like a `hir::Local` when type checking a function body, specifically:
* `GatherLocalsVisitor` overrides a new `Visitor::visit_let_expr` and does pretty much exactly what it does for `visit_local`, assigning a local type to the `hir::Let` ~~(they could be deduplicated but they are right next to each other, so at least we know they're the same)~~
* It reuses the code in `check_decl_local` to typecheck the `hir::Let`, simply returning 'bool' for the expression type after doing that.
* ~~`FnCtxt::check_expr_let` passes this local type in to `demand_scrutinee_type`, and then imitates check_decl_local's pattern checking~~
* ~~`demand_scrutinee_type` (the blindest change for me, please give this extra scrutiny) uses this local type instead of of creating a new one~~
* ~~Just realised the `check_expr_with_needs` was passing NoExpectation further down, need to pass the type there too. And apparently this Expectation API already exists.~~
Some other misc notes:
* ~~Is the clippy code supposed to be autoformatted? I tried not to give huge diffs but maybe some rustfmt changes simply haven't hit it yet.~~
* in `rustc_ast_lowering/src/block.rs`, I noticed some existing `self.alias_attrs()` calls in `LoweringContext::lower_stmts` seem to be copying attributes from the lowered locals/etc to the statements. Is that right? I'm new at this, I don't know.

Stabilize asm! and global_asm!
Tracking issue: #72016
It's been almost 2 years since the original [RFC](https://github.com/rust-lang/rfcs/pull/2850) was posted and we're finally ready to stabilize this feature!
The main changes in this PR are:
- Removing `asm!` and `global_asm!` from the prelude as per the decision in #87228.
- Stabilizing the `asm` and `global_asm` features.
- Removing the unstable book pages for `asm` and `global_asm`. The contents are moved to the [reference](https://github.com/rust-lang/reference/pull/1105) and [rust by example](https://github.com/rust-lang/rust-by-example/pull/1483).
- All links to these pages have been removed to satisfy the link checker. In a later PR these will be replaced with links to the reference or rust by example.
- Removing the automatic suggestion for using `llvm_asm!` instead of `asm!` if you're still using the old syntax, since it doesn't work anymore with `asm!` no longer being in the prelude. This only affects code that predates the old LLVM-style `asm!` being renamed to `llvm_asm!`.
- Updating `stdarch` and `compiler-builtins`.
- Updating all the tests.

Add new lint to warn when #[must_use] attribute should be used on a method
This lint is somewhat similar to https://rust-lang.github.io/rust-clippy/master/index.html#must_use_candidate but also different: it emits a warning by default and only targets methods (so not functions nor associated functions).
Someone suggested it to me after this tweet: https://twitter.com/m_ou_se/status/1466439813230477312

Parenthesize blocks in `needless_bool` suggestion
Because the `if .. {}` statement already puts the condition in expression scope, contained blocks would be parsed as complete

We identify such expressions and add parentheses. Note that we don't make a difference between normal and unsafe blocks because the parsing problems are the same for both.
This fixes#8052.

Prior to PR #91205, checking for errors in the overall obligation
would check checking the `ParamEnv`, due to an incorrect
`super_visit_with` impl. With this bug fixed, we will now
bail out of impl candidate assembly if the `ParamEnv` contains
any error types.
In practice, this appears to be overly conservative - when an error
occurs early in compilation, we end up giving up early for some
predicates that we could have successfully evaluated without overflow.
By only checking for errors in the predicate itself, we avoid causing
additional spurious 'type annotations needed' errors after a 'real'
error has already occurred.
With this PR, the diagnostic changes caused by PR #91205 are reverted.
