unwind/wasm: fix compile error by wrapping wasm_throw in unsafe block
This fix rust-std compile error on wasm32-unknown-unknown with panic=unwind because of `#![deny(unsafe_op_in_unsafe_fn)]`
Add regression test for #141738Closesrust-lang/rust#141738
- Add a regression test for rust-lang/rust#141738
- Using a struct constructor (`DefKind::Ctor(Struct, Const)`) as an array repeat count with `#![feature(min_generic_const_args)]` used to ICE in const alias normalization
- Fixed by rust-lang/rust#150704, which added const constructor support for mGCA. This test covers the **error path** (struct ctor where `usize` is expected), which was not covered by the tests in rust-lang/rust#150704
Include `library/stdarch` for `CURRENT_RUSTC_VERSION` updates
Our tool `replace-version-placeholder` uses the `tidy` file walker and its
directory filter, but that skips `library/stdarch` which we do need for public
stability markers. This PR adds a local filter function that explicitly allows
that path.
The commit for 1.94 `stdarch` updates is coming from beta rust-lang/rust#152187.
ci: Lock cross toolchain version and update docs
This PR locks the cross-toolchain component version to avoid unexpected changes when bumping crosstool-ng, and updates the toolchain configuration in the docs to match the actual setup.

Test(lib/win/net): Skip UDS tests when under Win7
Unix Domain Socket support has only been added to Windows since Windows 10 Insider Preview Build 17063. Thus, it has no chance of ever being supported under Windows 7, making current tests fail. This therefore adds the necessary in order to make the tests dynamically skip when run under Windows 7, 8, and early 10, as it does not trigger linker errors.

Improve write! and writeln! error when called without destination
Fixesrust-lang/rust#152493
Adds catch-all arms to `write!` and `writeln!` macros so that calling them without a destination (e.g., `write!("S")` instead of `write!(f, "S")`) gives a clear error instead of the cryptic "unexpected end of macro invocation" pointing at macro internals.

implement `carryless_mul`
tracking issue: https://github.com/rust-lang/rust/issues/152080
ACP: https://github.com/rust-lang/libs-team/issues/738
This defers to LLVM's `llvm.clmul` when available, and otherwise falls back to a method from the `polyval` crate ([link](https://github.com/RustCrypto/universal-hashes/blob/master/polyval/src/field_element/soft/soft64.rs)).
Some things are missing, which I think we can defer:
- the ACP has some discussion about additional methods, but I'm not sure exactly what is wanted or how to implement it efficiently
- the SIMD intrinsic is not yet `const` (I think I ran into a bootstrapping issue). That is fine for now, I think in `stdarch` we can't really use this intrinsic at the moment, we'd only want the scalar version to replace some riscv intrinsics.
- the SIMD intrinsic is not implemented for the gcc and cranelift backends. That should be reasonably straightforward once we have a const eval implementation though.
diagnostics: add note when param-env shadows global impl
This PR adds a diagnostics note when param-env shadows global impl as discussed in https://github.com/rust-lang/rust/issues/149910
It adds a note explaining that the definition is hidden by the generic bound.

`CurrentDepGraph`, `SerializedDepGraph`, `SerializedNodeHeader`, and
`EncoderState`.

the standalone `contains_explicit_ref_binding` function only checked for
`BindingAnnotation::Ref`, missing `BindingAnnotation::RefMut`. this caused
`let ref mut x = expr` to incorrectly take the coercion path instead of
preserving the exact type of the rhs expression. the method version used
for match arms already handles both `Ref` and `RefMut` correctly.
tests: adapt align-offset.rs for InstCombine improvements in LLVM 23
Upstream [has improved InstCombine](8d2078332c) so that it can shrink added constants using known zeroes, which caused a little bit of change in this test. As far as I can tell either output is fine, so we just accept both.

Do not require `'static` for obtaining reflection information.
tracking issue rust-lang/rust#142577
This does not affect the stable `TypeId::of`, as that has its own `'static` bound.
But it will allow obtaining `TypeId`s for non-static types via the reflection API. To obtain such a `TypeId` for any type, just use `Type::of::<(T,)>().kind` to extract the first field of a tuple.
This effectively reintroduces rust-lang/rust#41875, which @rust-lang/lang decided against allowing back in 2018 due to lack of sound use cases. We will thus need to have a T-lang meeting specifically about `TypeId` for non-static types before *stabilizing* any part of reflection (in addition to T-lang meetings about reflection in general). I'm adding an explicit point about this to the tracking issue.

UnsafePinned: implement opsem effects of UnsafeUnpin
This implements the next step for https://github.com/rust-lang/rust/issues/125735: actually making `UnsafePinned` have special opsem effects by suppressing the `noalias` *even if* the type is wrapped in an `Unpin` wrapper.
For backwards compatibility we also still keep the `Unpin` hack, i.e. a type must be both `Unpin` and `UnsafeUnpin` to get `noalias`.
Optimize indexing slices and strs with inclusive ranges
Instead of separately checking for `end == usize::MAX` and `end + 1 > slice.len()`, we can check for `end >= slice.len()`. Also consolidate all the str indexing related panic functions into a single function which reports the correct error depending on the arguments, as the slice indexing code already does.
The downside of all this is that the panic message is slightly less specific when trying to index with `[..=usize::MAX]`: instead of saying "attempted to index str up to maximum usize" it just says "end byte index {end} out of bounds". But this is a rare enough case that I think it is acceptable

Using a struct constructor (DefKind::Ctor(Struct, Const)) as an array
repeat count with `#![feature(min_generic_const_args)]` used to trigger
an ICE in const alias normalization. Add a regression test to ensure
the compiler produces a proper type error instead of panicking.
DepGraphQuery: correctly skip adding edges with not-yet-added nodes
Fixes https://github.com/rust-lang/rust/issues/142152.
The current logic already skips some edges, so I'm not sure how critical it is to have *all* the edges recorded, the logic seems to only be used for debug dumping.
Recording all edges requires supporting holes in the `LinkedGraph` data structure, to add nodes and edges out of order, https://github.com/rust-lang/rust/pull/151821 implements that at cost of complicating the data structure.

Again I left the use-sites as is since they are early uses.
