cleanup long shuffle mask literals
Use intrinsics for `sse2`, `sse41`, `avx2`, `avx512bw` The majority of implementations make use of `simd_shuffle` since that optimized through to the avx512 intrinsics that made use of the lower target feature intrinsics. Combined with masked stores, instruction tests would fail presumably due to the casting and clamping that the compiler couldn't see through. This is a known weakness as seen in the other masked stores like the truncating conversion stores.

Add const to `sse2`, `sse41`, `avx2`, and `avx512bw` functions and tests
use `intrinsics::simd` for interleaving store

…f-two-reads-writes aarch64: fix UB in non-power-of-two reads and writes
Rust 1.94 now passes constants directly to llvm.sqrt.f32 instead of
storing/loading via the stack.
- Updated the FileCheck pattern to match the new IR:
// CHECK: call float @llvm.sqrt.f32(float 4.000000e+00)
The test intent is unchanged: it still ensures the intrinsic is
emitted as a 'call' (not 'invoke').
- Removed unnecessary local variables and Drop usage to work in
`#![no_core]` mode with minicore.
- Added required crate attributes:
#![feature(no_core, lang_items)]
#![no_std]
#![no_core]
- Replaced `//@ only-riscv64` (host-based execution) with explicit
revisions for:
riscv32gc-unknown-linux-gnu
riscv64gc-unknown-linux-gnu
This ensures deterministic multi-target coverage in CI without
relying on the host architecture.
- Added `//@ needs-llvm-components: riscv` and
`//@ min-llvm-version: 21` for CI compatibility.

Parse `impl` restrictions
This PR implements the parsing logic for `impl` restrictions (e.g., `pub impl(crate) trait Foo {}`) as proposed in [RFC 3323](https://rust-lang.github.io/rfcs/3323-restrictions.html).
As the first step of the RFC implementation, this PR focuses strictly on the parsing phase. The new syntax is guarded by the `#![feature(impl_restriction)]` feature gate.
This implementation basically follows the pattern used in rust-lang#141754.

…egen_results, r=nnethercote Replace CodegenResults with CompiledModules This is already CodegenResults without CrateInfo. The driver can calculate the CrateInfo and pass it by-ref to the backend. Using CompiledModules makes it a bit easier to move some other things out of the backend as will be necessary for moving LTO to the link phase. Helps with rust-lang/compiler-team#908

Make `rustc_with_all_queries!` pass query modifiers as named values
This PR is a bold overhaul of how the proc-macro in `rustc_macros::query` passes query modifiers to the callback macros in `rustc_middle` and `rustc_query_impl`.
The existing approach passes modifiers as a list that looks like `[(arena_cache), (no_hash)]`. That style requires a family of helper macros (`if_arena_cache!`, `if_no_hash!`) to check for modifiers when consuming the query list.
This PR changes the proc-macro to instead pass modifiers like this:
```text
{
anon: false,
arena_cache: true,
cache_on_disk: false,
...
}
```
This style allows each of the callback macros to deconstruct the modifier list in a relatively straightforward way, by binding the true/false literals to variables like `$arena_cache:literal`.
One of the big advantages of this style is that we can write things like `#[cfg($arena_cache)]` and `#[cfg(not($arena_cache))]` to select blocks of code, eliminating the need for the `if_arena_cache!` family of helper macros.
In follow-up PRs, we can also try to take advantage of the new modifier style to pass richer information for some modifiers, such as `desc` or `cache_on_disk_if`. That could potentially make it more reasonable to get rid of the `_description_fns` and `_cache_on_disk_if_fns` modules, as proposed in rust-lang#153065.
