Print all features with --print target-features
This fixes `rustc --print target-features` with respect to aliases and tied features.
Before this change, the print command assumed that each LLVM feature corresponds exactly to one rustc feature. In the case of aliases and tied features, this assumption failed and some features (such as aarch64's "pacg") were missing. With this change, every target feature is listed.
Add slice to the stack allocated string comment
Precise that the "stack allocated string" is not a string but a string slice.

type alias impl trait: add tests showing that hidden type only outlives lifetimes that occur in bounds
fixes#103642https://github.com/rust-lang/rust/pull/102417 only made sure that hidden types cannot outlive lifetimes other than the ones mentioned on bounds, but didn't allow us to actually infer anything from that.

Also cache the stable hash of interned Predicates
continuation of https://github.com/rust-lang/rust/pull/94299
This is a small perf improvement and shares more code between `Ty` and `Predicate`
Add S-waiting-on-review autolabel.
This adds the S-waiting-on-review autolabel feature for new PRs. This was previously handled by highfive, but I neglected to include it in #9963.

Move `index_refutable_slice` to `pedantic`
During the creation, I out this lint into the nursery group to let it run in the wild before moving it to a commonly used group. This move never happened until now, though. It should be safe, as Clippy and I have been using it for months and there are no open issues for is :)

changelog: Move `index_refutable_slice` to `pedantic` (Now warn-by-default)
[#9975](https://github.com/rust-lang/rust-clippy/pull/9975)
Add a codegen-test that verifies inter-crate linkage with the static
relocation model. We expect all symbols that are part of a rust
compilation to end up in the same DSO, thus we expect `dso_local`
annotations.
Prevent DllImport from being attached to DSOLocal definitions in the
LLVM IR. The combination makes no sense, since definitions local to the
compilation unit will never be imported from external objects.
Additionally, LLVM will refuse the IR if it encounters the
combination (introduced in [1]):
if (GV.hasDLLImportStorageClass())
Assert(!GV.isDSOLocal(),
"GlobalValue with DLLImport Storage is dso_local!", &GV);
Right now, codegen-llvm will only apply DllImport to constants and rely
on call-stubs for functions. Hence, we simply extend the codegen of
constants to skip DllImport for any local definitions.
This was discovered when switching the EFI targets to the static
relocation model [2]. With this fixed, we can start another attempt at
this.

Don't lint `unnecessary_cast` in mixed macro context
fixes#9960
Time to start making a dent in this onslaught.
changelog: `unnecessary_cast`: Don't lint when the identifiers context differs from its binding's context for locals
There is code for converting `Attribute` (syntactic) to `MetaItem`
(semantic). There is also code for the reverse direction. The reverse
direction isn't really necessary; it's currently only used when
generating attributes, e.g. in `derive` code.
This commit adds some new functions for creating `Attributes`s directly,
without involving `MetaItem`s: `mk_attr_word`, `mk_attr_name_value_str`,
`mk_attr_nested_word`, and
`ExtCtxt::attr_{word,name_value_str,nested_word}`.
These new methods replace the old functions for creating `Attribute`s:
`mk_attr_inner`, `mk_attr_outer`, and `ExtCtxt::attribute`. Those
functions took `MetaItem`s as input, and relied on many other functions
that created `MetaItems`, which are also removed: `mk_name_value_item`,
`mk_list_item`, `mk_word_item`, `mk_nested_word_item`,
`{MetaItem,MetaItemKind,NestedMetaItem}::token_trees`,
`MetaItemKind::attr_args`, `MetaItemLit::{from_lit_kind,to_token}`,
`ExtCtxt::meta_word`.
Overall this cuts more than 100 lines of code and makes thing simpler.

After https://github.com/llvm/llvm-project/commit/8689f5e landed, LLVM takes the intersection of v8a and v8r as default.
This commit brings back v8a support by explicitly specifying v8a in the feature list.
This should solve #97724.
