test: run-make: skip when cross-compiling
This test fails when targeting aarch64 Android. Instead of adding yet another architecture here (and one that's increasingly more common as the host), let's replace the growing list of architectures with ignore-cross-compile.
Make the `config.src` handling for downloadable bootstrap more conservative
In particular, this supports build directories within an unrelated git repository. Fixes https://github.com/rust-lang/rust/issues/102562.
As a side effect, it will fall back to the old logic when the source directory is being built from a tarball within an unrelated git repository. However, that second case is unsupported and untested; we reserve the right to break it in the future.
`@cr1901` can you confirm this fixes your problem?
cc `@kleisauke,` I believe this will also fix your issue (although your use case still isn't supported).

`EscapeAscii` is not an `ExactSizeIterator`
Fixes#99878
Do we want/need `EscapeAscii` to be an `ExactSizeIterator`? I guess we could precompute the length of the output if so?
Fix gdb-cmd for rust-gdbgui
With https://github.com/cs01/gdbgui/pull/198, the way that gdbgui arguments were specified changed. I've tested this with program generated from `cargo new --bin` and it worked as gdbgui should.
Closes#76383.
add a few more assert_unsafe_precondition
Add debug-assertion checking for `ptr.read()`, `ptr.write(_)`, and `unreachable_unchecked.`
This is quite useful for [cargo-careful](https://github.com/RalfJung/cargo-careful).
This DOM cleanup changes the color of the triangle, from blue to black, but
since it's still a different color from the link it's next to, it should
still be noticeable.
Update browser UI test version
It added the possibility to concatenate strings and numbers and updated the `goto` command so it doesn't stand on its own anymore.

Remove `DefId` from some `SelectionCandidate` variants
They are both from `obligation.predicate.def_id()`, which do not need to be on the `SelectionCandidate`.

Fix MIR inlining of asm_unwind
The MIR inlining currently doesn't handle inline asm's unwind edge correctly.
This code will cause ICE:
```rust
struct D;
impl Drop for D {
fn drop(&mut self) {}
}
#[inline(always)]
fn foo() {
let _d = D;
unsafe { std::arch::asm!("", options(may_unwind)) };
}
pub fn main() {
foo();
}
```
This PR fixes this issue. I also take the opportunity to extract common code into a method.
Remove `mir::CastKind::Misc`
As discussed in #97649 `mir::CastKind::Misc` is not clear, this PR addresses that by creating a new enum variant for every valid cast.

Rewrite representability
* Improve placement of `Box` in the suggestion
* Multiple items in a cycle emit 1 error instead of an error for each item in the cycle
* Introduce `representability` query to avoid traversing an item every time it is used.
* Also introduce `params_in_repr` query to avoid traversing generic items every time it is used.
std: use futex in `Once`
Now that we have efficient locks, let's optimize the rest of `sync` as well. This PR adds a futex-based implementation for `Once`, which drastically simplifies the implementation compared to the generic version, which is provided as fallback for platforms without futex (Windows only supports them on newer versions, so it uses the fallback for now).
Instead of storing a linked list of waiters, the new implementation adds another state (`QUEUED`), which is set when there are waiting threads. These now use `futex_wait` on that state and are woken by the running thread when it finishes and notices the `QUEUED` state, thereby avoiding unnecessary calls to `futex_wake_all`.

Check `WhereClauseReferencesSelf` after all other object safety checks
This fixes the ICE because it causes us to detect another *non-lint* `MethodViolationCode` first, instead of breaking on `WhereClauseReferencesSelf`.
We could also approach this issue by instead returning a vector of *all* of the `MethodViolationCode`s, and just reporting the first one we see, but treating it as a hard error if we return both `WhereClauseReferencesSelf` and some other violation code -- let me know if this is desired.
Fixes#102762
Avoid repeated re-initialization of the BufReader buffer
Fixes https://github.com/rust-lang/rust/issues/102727
We accidentally removed this in https://github.com/rust-lang/rust/pull/98748. It looks so redundant. But it isn't.
The default `Read::read_buf` will defensively initialize the whole buffer, if any of it is indicated to be uninitialized. In uses where reads from the wrapped `Read` impl completely fill the `BufReader`, `initialized` and `filled` are the same, and this extra member isn't required. But in the reported issue, the `BufReader` wraps a `Read` impl which will _never_ fill the whole buffer. So the default `Read::read_buf` implementation repeatedly re-initializes the extra space in the buffer.
This adds back the extra `initialized` member, which ensures that the default `Read::read_buf` only zero-initialized the buffer once, and I've tried to add a comment which explains this whole situation.
unsafe keyword: trait examples and unsafe_op_in_unsafe_fn update
Having a safe `fn` in an `unsafe trait` vs an `unsafe fn` in a safe `trait` are pretty different situations, but the distinction is subtle and can confuse even seasoned Rust developers. So let's have explicit examples of both. I also removed the existing `unsafe trait` example since it was rather strange.
Also the `unsafe_op_in_unsafe_fn` lint can help disentangle the two sides of `unsafe`, so update the docs to account for that.
Use a macro to not have to copy-paste `ConstFnMutClosure::new(&mut fold, NeverShortCircuit::wrap_mut_2_imp)).0` everywhere
Also use that macro to replace a bunch of places that had custom closure-wrappers.
+35 -114 sounds good to me.
Remove `TypeckResults` from `InferCtxt`
`InferCtxt` currently has `in_progress_typeck_results` which is only used for some diagnostics during typeck. It adds a lifetime which propagates through a lot of code. This PR moves that field into a new helper struct `TypeErrCtxt`.
