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.
Further enhance `needless_borrow`, mildly refactor `redundant_clone`
This PR does the following:
* Moves some code from `redundant_clone` into a new `clippy_utils` module called `mir`, and wraps that code in a function called `dropped_without_further_use`.
* Relaxes the "is copyable" condition condition from #9136 by also suggesting to remove borrows from values dropped without further use. The changes involve the just mentioned function.
* Separates `redundant_clone` into modules.
Strictly speaking, the last bullet is independent of the others. `redundant_clone` is somewhat hairy, IMO. Separating it into modules makes it slightly less so, by helping to delineate what depends upon what.
I've tried to break everything up into digestible commits.

(`@Jarcho` I hope you don't mind.)
changelog: continuation of #9136
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.
internal: ⬆️ xflags
The main change here should be that flags are not inhereted, so
$ rust-analyzer analysis-stats . -v -v
would do what it should do
We also no longer Don\'t
Add `manual_filter` lint for `Option`
Share much of its implementation with `manual_map` and should greatly benefit from its previous feedback.
I'm sure it's possible to even more refactor both and would gladly take input on that as well as any clippy idiomatic usage, since this is my first lint addition.
I've added the lint to the complexity section for now, I don't know if every new lint needs to go in nursery first.
The matching could be expanded to more than `Some(<value>)` to lint on arbitrary struct matching inside the `Some` but I've left it like it was for `manual_map` for now. `needless_match::pat_same_as_expr` provides a more generic match example.

PR #98165 with commits 7c360dc117 and c1a2db3372
has moved all of the components of these modules into different places,
namely {std,core}::sync and {std,core}::cell. The empty
modules remained. As they are unstable, we can simply remove them.

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.

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`.
`normalize_and_add_constraints` doesn't add entries in `universe_causes`
when creating new universes, causing an ICE. Remove it!
Add spans to track normalization constraints.
Fix couple places where `universe_causes` is not updated correctly to
