…s for _mm_undefined_ps, _mm_prefetch, _mm_load_ps1, _mm_store_ps1
Already verified by assert_instr; no output to assert at runtime.
- Note that working directory matters
- Note that stdarch-gen-arm uses nightly
- Fix missing directory. Without this, it would print to stdout in one
  giant merged file.
Add more docs on how to run the generator
Add missing runtime tests for SSE alias intrinsics
Mark the LoongArch intrinsics as inline(always)
This updates the rust-version file to e4fdb55.
This commit removes unnecessary `transmute` calls to resolve clippy
warnings.
loongarch: Remove unnecessary `transmute` calls
tests/debuginfo/basic-stepping.rs: Remove FIXME related to ZSTs

We don't consider it a bug that users can't break on initialization of some non-zero sized types (see rust-lang#153941 and linked discussions), so it does not make sense to consider it a bug that users can't break on initialization of some zero-sized types.

Closes rust-lang#97083

r? compiler (see rust-lang#155352)
…etty, r=WaffleLapkin

Rearrange `rustc_ast_pretty`

`rustc_ast_pretty` has two modules, `pp::convenience` and `helpers`, that are small and silly. This PR eliminates them. Details in the individual commits.

r? @WaffleLapkin
triagebot: notify on diagnostic attribute changes

Did I get this right? 😆
…item, r=Kivooeo

Use `box_new` diagnostic item for Box::new suggestions

When look this part of code, I noticed this FIXME and fixed it :)
…r=petrochenkov

Small refactor of `QueryJob::latch` method

We can use `Option::get_or_insert_with` to avoid unwrapping there.
