This reduces the amount of time it takes to do the x check for rust-analyzer analysis from 12m16s to 3m34s when the bootstrap compiler is already downloaded.
If CI_JOB_NAME is not specified, it's supposed to fall back to the image name, which is `$image`, not `$IMAGE`. Failing to set the correct CI_JOB_NAME causes failures when running `dist-ohos-*` images locally.
This saves about 30s.
Make sure that compiler and linker don't optimize the section's contents away by adding the global holding the data to "llvm.used". This eliminates the need for a volatile load in the main shim; since the LLVM codegen backend is the only implementer of the corresponding trait function, remove it entirely.

Additionally, remove unused `tests/ui/auxiliary/svh-*` crates that are duplicates of `tests/ui/svh/auxiliary/svh-*`.
`tests/ui`: A New Order [26/N] > [!NOTE] > > Intermediate commits are intended to help review, but will be squashed prior to merge. Some `tests/ui/` housekeeping, to trim down number of tests directly under `tests/ui/`. Part of rust-lang#133895. r? ``@tgross35``
…o, r=petrochenkov make `cfg_select` a builtin macro tracking issue: rust-lang#115585 This parses mostly the same as the `macro cfg_select` version, except: 1. wrapping in double brackets is no longer supported (or needed): `cfg_select {{ /* ... */ }}` is now rejected. 2. in an expression context, the rhs is no longer wrapped in a block, so that this now works: ```rust fn main() { println!(cfg_select! { unix => { "foo" } _ => { "bar" } }); } ``` 3. a single wildcard rule is now supported: `cfg_select { _ => 1 }` now works I've also added an error if none of the rules evaluate to true, and warnings for any arms that follow the `_` wildcard rule. cc ``@traviscross`` if I'm missing any feature that should/should not be included r? ``@petrochenkov`` for the macro logic details

Check assoc consts and tys later like assoc fns
This PR
1. checks assoc consts and tys later like assoc fns
2. marks assoc consts appear in poly-trait-ref live
For assoc consts, considering
```rust
#![deny(dead_code)]
trait Tr { // ERROR trait `Tr` is never used
const I: Self;
}
struct Foo; //~ ERROR struct `Foo` is never constructed
impl Tr for Foo {
const I: Self = Foo;
}
fn main() {}
```
Current this will produce unused `I` instead of unused `Tr` and `Foo` ([play](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2024&gist=e0490d4a2d522cb70437b26e514a3d9c)), because `const I: Self = Foo;` will be added into the worklist at first:
```
error: associated constant `I` is never used
--> src/main.rs:4:11
|
3 | trait Tr { // ERROR trait `Tr` is never used
| -- associated constant in this trait
4 | const I: Self;
| ^
|
note: the lint level is defined here
--> src/main.rs:1:9
|
1 | #![deny(dead_code)]
| ^^^^^^^^^
error: could not compile `playground` (bin "playground") due to 1 previous error
```
This also happens to assoc tys, see the [new test](https://github.com/rust-lang/rust/compare/master...mu001999-contrib:rust:dead-code/impl-items?expand=1#diff-bf45fa403934a31c9d610a073ed2603d885e7e81572e8edf38b7f4e08a1f3531)
Fixes rust-lang#126729

…ieu,tgross35 slice: Mark `rotate_left`, `rotate_right` unstably const Tracking issue rust-lang#143812 - Add the const unstable `const_slice_rotate` feature - Mark `<[T]>::rotate_left` and `<[T]>::rotate_right` as const unstable The internal rotate functions use [`<*mut T>::replace`](https://doc.rust-lang.org/stable/core/primitive.pointer.html#method.replace) and [`ptr::swap_nonoverlapping`](https://doc.rust-lang.org/stable/core/ptr/fn.swap_nonoverlapping.html) which were const-stabilized in 1.88. Two changes were needed in the `rotate.rs` module to make these functions const: 1. A usage of `cmp::min` was replaced with a local function implementation of [`Ord::min`](https://doc.rust-lang.org/1.88.0/src/core/cmp.rs.html#1048-1053). 2. A `for start in 1..gcd` loop was changed to a while loop with an increment variable. This needs libs-api approval and cc-ing const-eval.
interpret/allocation: expose init + write_wildcards on a range Part of rust-lang/miri#4456, so that we can mark down when a foreign access to our memory happened. Should this also move `prepare_for_native_access()` itself into Miri, given that everything there can be implemented on Miri's side? r? ```@RalfJung```
…b-scripts-section, r=bjorn3 Preserve the .debug_gdb_scripts section Make sure that compiler and linker don't optimize the section's contents away by adding the global holding the data to `llvm.used`.

…ings, r=petrochenkov Resolve: merge `source_bindings` and `target_bindings` into `bindings` Attempts to merge the 2 fields `source_bindings` and `target_bindings` of `ImportKind::Single` into 1 field called `bindings`. r? ``@petrochenkov``
…resolution-bindings, r=petrochenkov Refactor resolve resolution bindings This pr does the work asked in rust-lang#142547 (comment). This part: > move the `(non)_glob_binding` change r? ``@petrochenkov``
constify `From` and `Into` tracking issue rust-lang#143773 r? ````@fee1-dead```` I did not mark any impls elsewhere as `const`, those can happen on their own timeframe and don't need to be part of this MVP. But if there are some core ones you think should be in there I'll happily add them, just couldn't think of any
…d, r=Kobzol Add --compile-time-deps argument for x check Together with skipping building C++ code in rustc_llvm for check, this reduces the amount of time it takes to do the x check for rust-analyzer analysis from 12m16s to 3m06s when the bootstrap compiler is already downloaded.
…oieni Fix fallback for CI_JOB_NAME If CI_JOB_NAME is not specified, it's supposed to fall back to the image name, which is `$image`, not `$IMAGE`. Failing to set the correct CI_JOB_NAME causes failures when running `dist-ohos-*` images locally.
clippy: fix test filtering when TESTNAME is empty Fixes rust-lang#143824. Turns out bootstrap was just fine, the TESTNAME logic in clippy was wrong... I still made this a rustc PR as that's where I did all the debugging. The bootstrap change is not really related, but it's comment-only so not worth a separate PR... adding the `test_args` is also part of what `prepare_cargo_test` would usually do so let's group the code properly.
…trace, r=Kobzol Fix command trace With the recent developments in centralization of command execution, we somehow broke the traces for command execution. This PR fixes that and add trace to stream command execution as well. r? ``@Kobzol``
