2025-08-22Add an experimental unsafe(force_target_feature) attribute.Luca Versari-61/+262
This uses the feature gate for https://github.com/rust-lang/rust/issues/143352, but is described in https://github.com/rust-lang/rfcs/pull/3820 which is strongly tied to the experiment.

2025-08-21Rollup merge of #145712 - notJoon:fix/outdate-link, r=lqdJacob Pratt-1/+1
Update outdated link in bound region comments While reading the implementation code for bound regions, I found that a link in the comments was outdated. I've updated it with a link to the corresponding documentation in the rustc dev guide that covers the same content. prev link: https://rustc-dev-guide.rust-lang.org/early-late-bound-params/early-late-bound-summary.html (404 error) updated: https://rustc-dev-guide.rust-lang.org/early_late_parameters.html

Instantiate higher-ranked binder with erased when checking `IntoIterator` predicate for query instability Fixes https://github.com/rust-lang/rust/issues/145652 which was introduced by https://github.com/rust-lang/rust/pull/139345 because we were skipping a binder before calling `Instance::try_resolve`. r? lcnr

2025-08-21Rollup merge of #145648 - bjorn3:tidy_deps_stricter, r=davidtwcoJacob Pratt-0/+33
Add two tidy dependency checks Deny duplicate dependencies for the standard library as it would almost certainly bloat executables. And deny proc-macro dependencies for the standard library as they would break cross-compilation.
2025-08-21Rollup merge of #145604 - compiler-errors:static-closure, r=fmeaseJacob Pratt-24/+67
Gate static closures behind a parser feature I'd like to gate `static ||` closures behind a feature gate, since we shouldn't allow people to take advantage of this syntax if it's currently unstable. Right now, since it's only rejected after ast lowering, it's accessible to macros. Let's crater this to see if we can claw it back without breaking anyone's code.

Consolidate panicking functions in `slice/index.rs` Consolidate all the panicking functions in `slice/index.rs` to use a single `slice_index_fail` function, similar to how it is done in `str/traits.rs`. Split off from https://github.com/rust-lang/rust/pull/145024
2025-08-21Rollup merge of #144780 - bjorn3:mir_build_debug, r=matthewjasperJacob Pratt-0/+37
Add a method to dump MIR in the middle of MIR building This makes it easier to debug issues with MIR building by inserting dump_for_debugging calls around the suspected code responsible for the bad MIR.
2025-08-21Rollup merge of #144613 - pantsman0:nintendo_switch_cpu_features, r=wesleywiserJacob Pratt-1/+1
aarch64-nintendo-switch-freestanding - Enable CPU features that are always available in a live system (crypto instructions, plus explicit NEON). ~~While some NEON and crypto features may not be supported on the Nintendo Switch at boot (e.g. on the a53 cores) and this has not been tested, the features will _always_ be available if running as a sysmodule or homebrew application under Horizon/Atmosphere.~~ EDIT: the a53 cores are fused out, these features are always available. This has been tested with local tools personally, as well as building [emuiibo](https://github.com/XorTroll/emuiibo) as it uses both `sha` and `aes` primitives. This was tested using inline assembly in previous versions, and in current versions by using the `aes`, `ctr`, `hmac`, and `sha2` crates. r? `@jam1garner` This ended up being much delayed from our discussions about updating this. I tested a number of individual features such as the `aes` and `sha2` target-features directly to avoid a warning message with the `crypto` feature, but that appears to be caused by https://github.com/rust-lang/rust/issues/96472 and is not actually an issue. There is also a decision to make here about explicitly enabling the `neon` feature. I am in favor of it to be explicit, but it is not necessary as it is already enabled by the `v8a` and `crypto` features. I will defer to your decision as it does not change the actual instructions available for codegen.

folkertdev:c-variadic-same-program-multiple-abis-arm, r=RalfJung,davidtwco c-variadic: multiple ABIs in the same program for arm similar to https://github.com/rust-lang/rust/pull/144379, but for arm, requested in https://github.com/rust-lang/rust/pull/144066. Quoting https://github.com/rust-lang/reference/issues/1946#issuecomment-3124555690 > `"aapcs"` specifically refers to the soft-float ABI where floating-point values are passed in integer registers. However for c-variadic functions, `aapcs` behaves the same as `C`: https://github.com/ARM-software/abi-aa/blob/main/aapcs32/aapcs32.rst#65parameter-passing > A variadic function is always marshaled as for the base standard. https://github.com/ARM-software/abi-aa/blob/main/aapcs32/aapcs32.rst#7the-standard-variants > This section applies only to non-variadic functions. For a variadic function the base standard is always used both for argument passing and result return. --- I also noticed that rustc currently emit more instructions than clang for c-variadic functions on arm, see https://godbolt.org/z/hMce9rnTh. I'll fix that separately. (edit: https://github.com/rust-lang/rust/pull/144549) try-job: armhf-gnu r? `@RalfJung`
