Create a similar rollup

seems unnecessary to use `macos-15-large` just for x86_64 support

provide a reminder on the signedness of a failed `assert_simm_bits`

Most of the changes in the JSON were merged earlier in the SVE intrinsics PR

Rustc pull update

Add AMX-AVX512 BF16 intrinsics

This change migrates a subset of LSX/LASX intrinsics to the portable `intrinsics::simd` interface. Only straightforward mappings are converted in this patch. Intrinsics that require more complex transformations or currently result in suboptimal code generation are intentionally left unchanged and will be migrated incrementally in follow-up patches.

these functions write to a raw pointer, and so are clearly unsafe to use

…, r=folkertdev stdarch subtree update Subtree update of `stdarch` to rust-lang/stdarch@6b174ad. Created using https://github.com/rust-lang/josh-sync. r? @ghost

Don't return dummy MacroData in `get_macro` I was experimenting with tool attributes and ast manipulation, and wasted some time figuring out that this was happening. AFAIK all users of `get_macro` are expecting an actual macro (and none were reading the dummy MacroData) so there should be no change in behavior.

…cation, r=wesleywiser tests/ui: allow spaces in hashbrown src normalization If one's home directory contains a space, the default location for the hashbrown source location also contains a space, and so the UI test normalization in issue-21763 fails to normalize as expected. While this new regex does not handle all valid paths, such as those beginning with `\\?\` or `\\name\`, this handles most absolute UNIX and Windows paths. Relative paths don't seem to be applicable.

What is this?

This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing 365c0e1 (parent) -> a4069f5 (this PR)

Test differences

Show 4 test diffs

Stage 1

[ui] tests/ui/cfg/reserved-macro-names-rename.rs: [missing] -> pass (J1)

Stage 2

[ui] tests/ui/cfg/reserved-macro-names-rename.rs: [missing] -> pass (J0)

Additionally, 2 doctest diffs were found. These are ignored, as they are noisy.

aarch64-gnu-debug: 1h 18m -> 1h 6m (-15.1%)

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.
