2025-09-13Rollup merge of #146389 - jdonszelmann:no-std, r=oli-obkJana Dönszelmann-0/+24
Convert `no_std` and `no_core` to the new attribute infrastructure r? ```@oli-obk``` Also added a test for these, since we didn't have any and I was kind of surprised new diagnostics didn't break anything hehe

2025-09-10Rollup merge of #146178 - folkertdev:static-align, ↵Matthias Krüger-0/+28
r=jdonszelmann,ralfjung,traviscross Implement `#[rustc_align_static(N)]` on `static`s Tracking issue: https://github.com/rust-lang/rust/issues/146177 ```rust #![feature(static_align)] #[rustc_align_static(64)] static SO_ALIGNED: u64 = 0; ``` We need a different attribute than `rustc_align` because unstable attributes are tied to their feature (we can't have two unstable features use the same unstable attribute). Otherwise this uses all of the same infrastructure as `#[rustc_align]`. r? `@traviscross`

add doc-hidden to exports in attribute prelude Seems to fix rust-lang/rust#145870, at least temporarily.

2025-08-22Rollup merge of #145573 - veluca93:unsafe-force-target-feature, r=davidtwcoJacob Pratt-40/+78
Add an experimental unsafe(force_target_feature) attribute. 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.
