A bit of an inelegant fix but given that the error is created only after call to `const_eval_poly()` and that the calling function cannot propagate the error anywhere else, the error has to be explicitly handled inside `mono_item.rs`.
``` error: `S2<'_>` is forbidden as the type of a const generic parameter --> $DIR/lifetime-in-const-param.rs:5:23 | LL | struct S<'a, const N: S2>(&'a ()); | ^^ | = note: the only supported types are integers, `bool` and `char` help: add `#![feature(adt_const_params)]` to the crate attributes to enable more complex and user defined types | LL + #![feature(adt_const_params)] | ``` Fix rust-lang#55941.

…y-generic-tys, r=compiler-errors Reject overly generic assoc const binding types Split off from rust-lang#119385 to make rust-lang#119385 easier to review. --- In the *instantiated* type of assoc const bindings 1. reject **early-bound generic params** * Provide a rich error message instead of ICE'ing ([rust-lang#108271](rust-lang#108271)). * This is a temporary and semi-artificial restriction until the arrival of *generic const generics*. * It's quite possible that rustc could already perfectly support this subset of generic const generics if we just removed some checks (some `.no_bound_vars().expect(…)`) but even if that was the case, I'd rather gate it behind a new feature flag. Reporting an error instead of ICE'ing is a good first step towards an eventual feature gate error. 2. reject **escaping late-bound generic params** * They lead to ICEs before & I'm pretty sure that they remain incorrect even in a world with *generic const generics* --- Together with rust-lang#118668 & rust-lang#119385, this supersedes rust-lang#118360. Fixes rust-lang#108271.
…ler-errors never patterns: suggest `!` patterns on non-exhaustive matches When a match is non-exhaustive we now suggest never patterns whenever it makes sense. r? `@compiler-errors`

…p_remove, r=Amanieu Improve wording of `Vec::swap_remove` This improve the wording for `Vec::swap_remove`.
core: document default attribute stabilization As of now, the first release which stabilized the `#[default]` macro for the deriving the `Default` trait for enus is not documented. I have had to search the [`RELEASES.md`](https://github.com/rust-lang/rust/blob/master/RELEASES.md) when making sure my code would be accepted by an older Rust compiler. I just added a line in the doc comment since, as far as I know, there's no option to pass to the `#[stable()]` attribute. I am open to improvements in the wording.
…ls, r=compiler-errors `NormalizesTo`: return nested goals to caller Fixes the regression of `paperclip-core`. see https://hackmd.io/IsVAafiOTAaPIFcUxRJufw for more details. r? ``@compiler-errors``
…manieu Fix ICE: `global_asm!()` Don't Panic When Unable to Evaluate Constant Fixes rust-lang#121099 A bit of an inelegant fix but given that the error is created only after call to `const_eval_poly()` and that the calling function cannot propagate the error anywhere else, the error has to be explicitly handled inside `mono_item.rs`. r? ``@Amanieu``
…Gomez Fix heading anchors in doc pages. This fixes the heading anchors on the standalone doc pages (the index, releases, etc.) so that the § symbol is only shown when the user hovers over the heading. This was changed in rust-lang#117662, but this CSS was not updated.
Fix a typo in the 1.77.0 relnotes
…jubilee Remove redundant files, rename base riscv32 file Fixes a mistake I made in rust-lang#117874.
… r=oli-obk Detect allocator for box in `must_not_suspend` lint I don't expect this to happen in practice, but better to check than not. Fixes rust-lang#122643
