Fix accidentally not emitting overflowing literals lints anymore in patterns by oli-obk · Pull Request #136393 · rust-lang/rust

oli-obk · 2025-02-01T17:22:18Z

This was regressed in #134228 (not in beta yet).

The issue was that previously we nested hir::Expr inside hir::PatKind::Lit, so it was linted by the expression code.

So now I've set it up for visitors to be able to directly visit literals and get all literals

Overall result: no relevant changes - no action needed

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Given this has regressed in #137893 but seems to be an accepted change (comment), I'm going to mark this for the release notes, T-release will decide 🙂

Libraries --------- - The type of `FromBytesWithNulError` in `CStr::from_bytes_with_nul(bytes: &[u8]) -> Result<&Self, FromBytesWithNulError>` was [changed from an opaque struct to an enum] (rust-lang/rust#134143), allowing users to examine why the conversion failed. - [Remove `RustcDecodable` and `RustcEncodable`.] (rust-lang/rust#134272) - [Deprecate libtest's `--logfile` option.] (rust-lang/rust#134283) - [On recent versions of Windows, `std::fs::remove_file` will now remove read-only files.] (rust-lang/rust#134679) Stabilized APIs --------------- - [`{float}::next_down`] (https://doc.rust-lang.org/stable/std/primitive.f64.html#method.next_down) - [`{float}::next_up`] (https://doc.rust-lang.org/stable/std/primitive.f64.html#method.next_up) - [`<[_]>::get_disjoint_mut`] (https://doc.rust-lang.org/stable/std/primitive.slice.html#method.get_disjoint_mut) - [`<[_]>::get_disjoint_unchecked_mut`] (https://doc.rust-lang.org/stable/std/primitive.slice.html#method.get_disjoint_unchecked_mut) - [`slice::GetDisjointMutError`] (https://doc.rust-lang.org/stable/std/slice/enum.GetDisjointMutError.html) - [`HashMap::get_disjoint_mut`] (https://doc.rust-lang.org/std/collections/hash_map/struct.HashMap.html#method.get_disjoint_mut) - [`HashMap::get_disjoint_unchecked_mut`] (https://doc.rust-lang.org/std/collections/hash_map/struct.HashMap.html#method.get_disjoint_unchecked_mut) - [`NonZero::count_ones`] (https://doc.rust-lang.org/stable/std/num/struct.NonZero.html#method.count_ones) - [`Vec::pop_if`] (https://doc.rust-lang.org/std/vec/struct.Vec.html#method.pop_if) - [`sync::Once::wait`] (https://doc.rust-lang.org/stable/std/sync/struct.Once.html#method.wait) - [`sync::Once::wait_force`] (https://doc.rust-lang.org/stable/std/sync/struct.Once.html#method.wait_force) - [`sync::OnceLock::wait`] (https://doc.rust-lang.org/stable/std/sync/struct.OnceLock.html#method.wait) These APIs are now stable in const contexts: - [`hint::black_box`] (https://doc.rust-lang.org/stable/std/hint/fn.black_box.html) - [`io::Cursor::get_mut`] (https://doc.rust-lang.org/stable/std/io/struct.Cursor.html#method.get_mut) - [`io::Cursor::set_position`] (https://doc.rust-lang.org/stable/std/io/struct.Cursor.html#method.set_position) - [`str::is_char_boundary`] (https://doc.rust-lang.org/stable/std/primitive.str.html#method.is_char_boundary) - [`str::split_at`] (https://doc.rust-lang.org/stable/std/primitive.str.html#method.split_at) - [`str::split_at_checked`] (https://doc.rust-lang.org/stable/std/primitive.str.html#method.split_at_checked) - [`str::split_at_mut`] (https://doc.rust-lang.org/stable/std/primitive.str.html#method.split_at_mut) - [`str::split_at_mut_checked`] (https://doc.rust-lang.org/stable/std/primitive.str.html#method.split_at_mut_checked) Cargo ----- - [When merging, replace rather than combine configuration keys that refer to a program path and its arguments.] (rust-lang/cargo#15066) - [Error if both `--package` and `--workspace` are passed but the requested package is missing.] (rust-lang/cargo#15071) This was previously silently ignored, which was considered a bug since missing packages should be reported. - [Deprecate the token argument in `cargo login` to avoid shell history leaks.] (rust-lang/cargo#15057) - [Simplify the implementation of `SourceID` comparisons.] (rust-lang/cargo#14980) This may potentially change behavior if the canonicalized URL compares differently in alternative registries. Rustdoc ----- - [Add a sans-serif font setting.] (rust-lang/rust#133636) Compatibility Notes ------------------- - [The `wasm_c_abi` future compatibility warning is now a hard error.] (rust-lang/rust#133951) Users of `wasm-bindgen` should upgrade to at least version 0.2.89, otherwise compilation will fail. - [Remove long-deprecated no-op attributes `#![no_start]` and `#![crate_id]`.] (rust-lang/rust#134300) - [The future incompatibility lint `cenum_impl_drop_cast` has been made into a hard error.] (rust-lang/rust#135964) This means it is now an error to cast a field-less enum to an integer if the enum implements `Drop`. - [SSE2 is now required for "i686" 32-bit x86 hard-float targets; disabling it causes a warning that will become a hard error eventually.] (rust-lang/rust#137037) To compile for pre-SSE2 32-bit x86, use a "i586" target instead. Internal Changes ---------------- These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - [Build the rustc on AArch64 Linux with ThinLTO + PGO.] (rust-lang/rust#133807) The ARM 64-bit compiler (AArch64) on Linux is now optimized with ThinLTO and PGO, similar to the optimizations we have already performed for the x86-64 compiler on Linux. This should make it up to 30% faster.

Pkgsrc changes: * Drop support for building now old 1.76.0 rust natively on 32-bit NetBSD arm ports, pushing those to use the rust-bin variant instead. * Use of newer GCC on NetBSD/powerpc turned out to not be required, given that your kernel and user-land is new enough. >= 10.0 release? * Checksum updates. Upstream changes: Version 1.86.0 (2025-04-03) ========================== Language -------- - [Stabilize upcasting trait objects to supertraits.] (rust-lang/rust#134367) - [Allow safe functions to be marked with the `#[target_feature]` attribute.] (rust-lang/rust#134090) - [The `missing_abi` lint now warns-by-default.] (rust-lang/rust#132397) - Rust now lints about double negations, to catch cases that might have intended to be a prefix decrement operator (`--x`) as written in other languages. This was previously a clippy lint, `clippy::double_neg`, and is [now available directly in Rust as `double_negations`.] (rust-lang/rust#126604) - [More pointers are now detected as definitely not-null based on their alignment in const eval.] (rust-lang/rust#133700) - [Empty `repr()` attribute applied to invalid items are now correctly rejected.] (rust-lang/rust#133925) - [Inner attributes `#![test]` and `#![rustfmt::skip]` are no longer accepted in more places than intended.] (rust-lang/rust#134276) Compiler -------- - [Debug-assert that raw pointers are non-null on access.] (rust-lang/rust#134424) - [Change `-O` to mean `-C opt-level=3` instead of `-C opt-level=2` to match Cargo's defaults.] (rust-lang/rust#135439) - [Fix emission of `overflowing_literals` under certain macro environments.] (rust-lang/rust#136393) Platform Support ---------------- - [Replace `i686-unknown-redox` target with `i586-unknown-redox`.] (rust-lang/rust#136698) - [Increase baseline CPU of `i686-unknown-hurd-gnu` to Pentium 4.] (rust-lang/rust#136700) - New tier 3 targets: - [`{aarch64-unknown,x86_64-pc}-nto-qnx710_iosock`] (rust-lang/rust#133631).
