@rustbot modify labels: rollup

Create a similar rollup

thaliaarchi and others added 21 commits March 27, 2025 16:49
Currently, `write` for stdout and stderr on Trusty is implemented with
the semantics of `write_all`. Instead, call the underlying syscall only
once in `write` and use the default implementation of `write_all` like
other platforms. Also, implement `write_vectored` by adding support for
`IoSlice`.

Refactor stdin to reuse the unsupported type like rust-lang#136769.
Generates branchless code
This avoids generating extra instructions that needlessly modify the slice's pointer
Optimize slice {Chunks,Windows}::nth

I've noticed that the `nth` functions on slice iters had non-optimized-out bounds checks.

The new implementation even generates branchless code.
Trusty: Implement `write_vectored` for stdio

Currently, `write` for stdout and stderr on Trusty is implemented with the semantics of `write_all`. Instead, call the underlying syscall only once in `write` and use the default implementation of `write_all` like other platforms. Also, implement `write_vectored` by adding support for `IoSlice`.

Refactor stdin to reuse the unsupported type like rust-lang#136769.

It requires rust-lang#138875 to fix the build for Trusty, though they do not conflict and can merge in either order.

Add `slice::align_to_uninit_mut`

Add new `slice::align_to_uninit_mut` method.

Tracking issue: rust-lang#139062

ACP: rust-lang/libs-team#564
…r=Urgau

Add `*_value` methods to proc_macro lib

This is the (re-)implementation of rust-lang/libs-team#459.

It allows to get the actual value (unescaped) of the different string literals.

It was originally done in rust-lang#136355 but it broke the artifacts build so we decided to move the crate to crates.io to go around this limitation.

Part of rust-lang#136652.

Considering this is a copy-paste of the originally approved PR, no need to go through the whole process again. \o/

Check if merged attributes list is empty in expr

Fixes rust-lang#139373

In the example code, an [`UnrecognizedReprHint`](https://github.com/rust-lang/rust/blob/6b5ccfc87f59ab017032e430d4d358b4989735da/compiler/rustc_attr_parsing/src/attributes/repr.rs#L155) error is output, and the list of merged attributes becomes empty. This causes a [panic](https://github.com/rust-lang/rust/blob/6b5ccfc87f59ab017032e430d4d358b4989735da/compiler/rustc_ast_lowering/src/lib.rs#L618) to occur. So, it's necessary to check if merged attributes list is empty as other functions do.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
