This sentence was unnecessarily complex; try to simplify it.

The overflow-checks codegen test was failing on riscv64gc target because the FileCheck pattern did not account for ABI extension attributes. RISC-V LP64 ABI requires integer types smaller than XLEN (64-bit) to be zero-extended or sign-extended to register width. For u8 parameters, RISC-V generates: i8 noundef zeroext %a, i8 noundef zeroext %b While x86_64 and aarch64 generate: i8 noundef %a, i8 noundef %b The original CHECK pattern only matched the format without the `zeroext` attribute, causing test failures on RISC-V. This patch makes the zeroext attribute optional in the FileCheck pattern using `{{( zeroext)?}}`, allowing the test to pass on architectures that add ABI extension attributes (e.g., RISC-V). Test results before fix: - x86_64-unknown-linux-gnu: 3 passed - aarch64-unknown-linux-gnu: 3 passed - riscv64gc-unknown-linux-gnu: 1 passed, 2 failed Test results after fix: - x86_64-unknown-linux-gnu: 3 passed - aarch64-unknown-linux-gnu: 3 passed - riscv64gc-unknown-linux-gnu: 3 passed

This enables rustup distribution of the rust-std component for the riscv64a23-unknown-linux-gnu target, allowing users to install it via `rustup target add riscv64a23-unknown-linux-gnu`.

…imulacrum `vec_recycle`: implementation Tracking issue: rust-lang#148227 Going with the `TransmuteFrom` approach suggested in rust-lang/libs-team#674 (comment), but a bit simplified. Currently does not work in some places where it should due to the limitations of the current implementation of the transmutability analysis: rust-lang#148227 (comment)

…_postings_from_string, r=GuillaumeGomez Micro-optimize rustdoc search index parsing This should pre-allocate the correct size for the `slot` vec. Not sure how much of a difference it'll make, but let's see.

…parts, r=Mark-Simulacrum Stabilize vec_into_raw_parts This stabilizes `Vec::into_raw_parts()` and `String::into_raw_parts()` per FCP in rust-lang#65816 (comment). While this _does not_ stabilize `Vec::into_parts()`, I fixed up the examples that said they were waiting for `vec_into_raw_parts`. As `Vec::from_parts()` and `Vec::into_parts()` are covered by the same feature `box_vec_non_null`, any doctest that uses `Vec::from_parts()` can also use `Vec::into_parts()` (and same for allocator-aware versions).

…11-25, r=Mark-Simulacrum Bump library dependencies rust-lang#145849 (comment)

…ocs, r=Mark-Simulacrum tweak primitive reference docs This is a docs-only change for primitive reference. I noticed a typo ("safe to use at type `T`") and fixed it to read "safe to use *as* type `T`". While reading over the whole page, I also noticed another sentence that was hard to read. I tried to improve it: feel free to comment on the wisdom of this change...

…ecks-test-fail, r=Mark-Simulacrum Fix overflow-checks test for RISC-V target The overflow-checks codegen test was failing on riscv64gc target because the FileCheck pattern did not account for ABI extension attributes.

…-tier2, r=Mark-Simulacrum Add riscv64a23-unknown-linux-gnu to build-manifest TARGETS This enables rustup distribution of the rust-std component for the riscv64a23-unknown-linux-gnu target (Previous PR rust-lang#148435 missed this step.)

…Kivooeo Add another *ExprWithBlock* test for `try` blocks Looking to address this open item from rust-lang#31436 > Add a test confirming that it's an `ExprWithBlock`, so works in a match arm without a comma It turns out that rust-lang#120540 addressed that one, but it made me think of this other case that probably ought to have some kind of test as well.

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.

Our benchmarks found a performance regression caused by this PR.
This might be an actual regression, but it can also be just noise.

Next Steps:

If the regression was expected or you think it can be justified,
please write a comment with sufficient written justification, and add
@rustbot label: +perf-regression-triaged to it, to mark the regression as triaged.
If you think that you know of a way to resolve the regression, try to create
a new PR with a fix for the regression.
If you do not understand the regression or you think that it is just noise,
you can ask the @rust-lang/wg-compiler-performance working group for help (members of this group
were already notified of this PR).

The clap_derive result looks pretty clearly bimodal.

The secondary regressions are plausibly real, but don’t seem big enough to be worth investigating.
