Per a comment on #70516 this changes `eq_ignore_ascii_case` to take the generic parameter `S: AsRef<OsStr>` by value instead of by reference.
This is technically a breaking change to an unstable method. I think the only way it would break is if you called this method with an explicit type parameter, ie `my_os_str.eq_ignore_ascii_case::<str>("foo")` becomes `my_os_str.eq_ignore_ascii_case::<&str>("foo")`.
Besides that, I believe it is overall more flexible since it can now take an owned `OsString` for example.
If this change should be made in some other PR (like #80193) then please just close this.
Add some links to the cell docs.
This adds a few links to the cell module docs to make it a little easier to navigate to the types and functions it references.
Add a new ABI to support cmse_nonsecure_call
This adds support for the `cmse_nonsecure_call` feature to be able to perform non-secure function call.
See the discussion on Zulip [here](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Support.20for.20callsite.20attributes/near/223054928).
This is a followup to #75810 which added `cmse_nonsecure_entry`. As for that PR, I assume that the changes are small enough to not have to go through a RFC but I don't mind doing one if needed 😃
I did not yet create a tracking issue, but if most of it is fine, I can create one and update the various files accordingly (they refer to the other tracking issue now).
On the Zulip chat, I believe `@jonas-schievink` volunteered to be a reviewer 💯
Update test-various to Ubuntu 20.04
The test command-setgroups.rs is adjusted to skip on musl, where `sysconf(_SC_NGROUPS_MAX)` always returns a dummy value of 32, even though the actual value is 65536. I'm not sure why this only became a problem now, as the information I found indicates that this value changed in kernel version 2.6.4, which is ages ago.
I'm a bit unsure whether this one will go through, because I locally also saw a failure in std-backtrace.rs which went away on subsequent runs, and also had port assignment failures, but I think those might be on my side. I'm kind of curious how the code in b122908617/library/std/src/net/test.rs (L43-L56) is supposed to work, as the directory names it checks don't seem to appear anywhere else.

In particular: the specific code to define LLVM_VERSION_11_PLUS here was, for
some reason, using `$(shell ...)` with bash-specific variable replacement code.
On non-bash platforms like dash, that `shell` invocation would fail, and the
LLVM_VERSION_11_PLUS check would always fail, the test would always be ignored,
and thus be treated as a "success" (in the sense that `--bless` would never do
anything).
This was causing me a lot of pain.
We used to ignore `forbid(group)` scenarios completely. This changed
in #78864, but that led to a number of regressions (#80988, #81218).
This PR introduces a future compatibility warning for the case where
a group is forbidden but then an individual lint within that group
is allowed. We now issue a FCW when we see the "allow", but permit
it to take effect.
Improve wording of suggestion about accessing field
Follow-up to #81504
The compiler at this moment suggests "you might have meant to use field `b` of type `B`", sounding like it's type `B` which has the field `b`.

Fix bug with assert!() calling the wrong edition of panic!().
The span of `panic!` produced by the `assert` macro did not carry the right edition. This changes `assert` to call the right version.
Also adds tests for the 2021 edition of panic and assert, that would've caught this.
rustbuild: Don't build compiler twice for error-index-generator.
When using `--stage=1`, the error-index-generator was forcing the compiler to be built twice. This isn't necessary; the error-index-generator just needs the same unusual logic that rustdoc uses to build with stage minus one.
`--stage=0` and `--stage=2` should be unaffected by this change.

Add doc aliases for "delete"
This patch adds doc aliases for "delete". The added aliases are supposed to reference usages `delete` in other programming languages.
- `HashMap::remove`, `BTreeMap::remove` -> `Map#delete` and `delete` keyword in JavaScript.
- `HashSet::remove`, `BTreeSet::remove` -> `Set#delete` in JavaScript.
- `mem::drop` -> `delete` keyword in C++.
- `fs::remove_file`, `fs::remove_dir`, `fs::remove_dir_all`-> `File#delete` in Java, `File#delete` and `Dir#delete` in Ruby.
Before this change, searching for "delete" in documentation returned no results.
Add better diagnostic for unbounded Abst. Const
~~In the case where a generic abst. const requires a trivial where bound: `where TypeWithConst<const_fn(N)>: ,`,
instead of requiring a where bound, just check that only consts are being substituted in to skip over where check.~~
~~This is pretty sketchy, but I think it works. Presumably, if there is checking for type bounds added later, it can first check nested requirements, and see if they're satisfied by the current `ParamEnv`.~~
Changed the diagnostic to add a better example, which is more practical than what was previously proposed.

sys: use `process::abort()` instead of `arch::wasm32::unreachable()`
Rationale:
- `abort()` lowers to `wasm32::unreachable()` anyway.
- `abort()` isn't `unsafe`.
- `abort()` matches the comment better.
- `abort()` avoids confusion by future readers (e.g. https://github.com/rust-lang/rust/pull/81527): the naming of wasm's `unreachable` instruction is a bit unfortunate because it is not related to the `unreachable()` intrinsic (intended to trigger UB).
Codegen is likely to be different since `unreachable()` is `inline` while `abort()` is `cold`. Since it doesn't look like we are expecting here to trigger this case, the latter seems better anyway.
Add AArch64 big-endian and ILP32 targets
This PR adds 3 new AArch64 targets:
- `aarch64_be-unknown-linux-gnu`
- `aarch64-unknown-linux-gnu_ilp32`
- `aarch64_be-unknown-linux-gnu_ilp32`
It also fixes some ABI issues on big-endian ARM and AArch64.
Add .editorconfig
This adds a .editorconfig file to rust-lang/rust, matching Clippy's. It's not clear that this will benefit many people, but the cost is low and the rewards are potentially meaningful.

Upgrade Chalk
~~Blocked on rust-lang/chalk#670~~
~~Now blocked on rust-lang/chalk#680 and release~~
In addition to the straight upgrade, I also tried to fix some tests by properly returning variables and max universes in the solution. Unfortunately, this actually triggers the same perf problem that rustc traits code runs into in `canonicalizer`. Not sure what the root cause of this problem is, or why it's supposed to be solved in chalk.
