…on-ZST member This ensures that `MaybeUninit<T>` has the same ABI as `T` when passed through an `extern "C"` function. Fixes rust-lang#115481.
…r-errors style-guide: Add section on bugs, and resolving bugs
…nion-abi, r=bjorn3 rustc_target/riscv: Fix passing of transparent unions with only one non-ZST member This ensures that `MaybeUninit<T>` has the same ABI as `T` when passed through an `extern "C"` function. Fixes rust-lang#115481. r? `@RalfJung`
…r=oli-obk Detect cycle errors hidden by opaques during monomorphization Opaque types may reveal to projections, which themselves normalize to opaques. We don't currently normalize when checking that opaques are cyclical, and we may also not know that the opaque is cyclical until monomorphization (see `tests/ui/type-alias-impl-trait/mututally-recursive-overflow.rs`). Detect cycle errors in `normalize_projection_ty` and report a fatal overflow (in the old solver). Luckily, this is already detected as a fatal overflow in the new solver. Fixes rust-lang#112047
…_in_docs-warning, r=notriddle Custom code classes in docs warning Fixes rust-lang#115938. This PR does two things: 1. Unless the `custom_code_classes_in_docs` feature is enabled, it will use the old codeblock tag parser. 2. If there is a codeblock tag that starts with a `.`, it will emit a behaviour change warning. Hopefully this is the last missing part for this feature until stabilization. Follow-up of rust-lang#110800. r? `@notriddle`
