2025-06-15Rollup merge of #134661 - dtolnay:prefixattr, r=fmeaseLeón Orell Valerian Liehr-11/+11
Reduce precedence of expressions that have an outer attr Previously, `-Zunpretty=expanded` would expand this program as follows: ```rust #![feature(stmt_expr_attributes)] macro_rules! repro { ($e:expr) => { #[allow(deprecated)] $e }; } #[derive(Default)] struct Thing { #[deprecated] field: i32, } fn main() { let thing = Thing::default(); let _ = repro!(thing).field; } ``` ```rs #![feature(prelude_import)] #![feature(stmt_expr_attributes)] #[prelude_import] use std::prelude::rust_2021::*; #[macro_use] extern crate std; struct Thing { #[deprecated] field: i32, } #[automatically_derived] impl ::core::default::Default for Thing { #[inline] fn default() -> Thing { Thing { field: ::core::default::Default::default() } } } fn main() { let thing = Thing::default(); let _ = #[allow(deprecated)] thing.field; } ``` This is not the correct expansion. The correct output would have `(#[allow(deprecated)] thing).field` with the attribute applying only to `thing`, not to `thing.field`.

2025-06-14Rollup merge of #141811 - mejrs:bye_locals, r=compiler-errorsMatthias Krüger-48/+5
Unimplement unsized_locals Implements https://github.com/rust-lang/compiler-team/issues/630 Tracking issue here: https://github.com/rust-lang/rust/issues/111942 Note that this just removes the feature, not the implementation, and does not touch `unsized_fn_params`. This is because it is required to support `Box<dyn FnOnce()>: FnOnce()`. There may be more that should be removed (possibly in follow up prs) - the `forget_unsized` function and `forget` intrinsic. - the `unsized_locals` test directory; I've just fixed up the tests for now - various codegen support for unsized values and allocas cc ``@JakobDegen`` ``@oli-obk`` ``@Noratrieb`` ``@programmerjake`` ``@bjorn3`` ``@rustbot`` label F-unsized_locals Fixes rust-lang/rust#79409
2025-06-14Rollup merge of #140593 - m-ou-se:some-temp, r=NadrierilMatthias Krüger-1/+0
Temporary lifetime extension through tuple struct and tuple variant constructors This makes temporary lifetime extension work for tuple struct and tuple variant constructors, such as `Some()`. Before: ```rust let a = &temp(); // Extended let a = Some(&temp()); // Not extended :( let a = Some { 0: &temp() }; // Extended ``` After: ```rust let a = &temp(); // Extended let a = Some(&temp()); // Extended let a = Some { 0: &temp() }; // Extended ``` So, with this change, this works: ```rust let a = Some(&String::from("hello")); // New: String lifetime now extended! println!("{a:?}"); ``` Until now, we did not extend through tuple struct/variant constructors (like `Some`), because they are function calls syntactically, and we do not want to extend the String lifetime in: ```rust let a = some_function(&String::from("hello")); // String not extended! ``` However, it turns out to be very easy to distinguish between regular functions and constructors at the point where we do lifetime extension. In practice, constructors nearly always use UpperCamelCase while regular functions use lower_snake_case, so it should still be easy to for a human programmer at the call site to see whether something qualifies for lifetime extension or not. This needs a lang fcp. --- More examples of what will work after this change: ```rust let x = Person { name: "Ferris", job: Some(&Job { // `Job` now extended! title: "Chief Rustacean", organisation: "Acme Ltd.", }), }; dbg!(x); ``` ```rust let file = if use_stdout { None } else { Some(&File::create("asdf")?) // `File` now extended! }; set_logger(file); ``` ```rust use std::path::Component; let c = Component::Normal(&OsString::from(format!("test-{num}"))); // OsString now extended! assert_eq!(path.components.first().unwrap(), c); ```

This works in rustc. This change isn't motivated by any real code. I just learned about it and decided to see why it doesn't work with rust-analyzer.
