LLVM 24 got smarter and is able to mark some more things noundef, which showed up in some of our test checks.
When building `core` with `--cfg no_io_statics`, the compiler warns:
error: unused variable: `f`
--> .../library/core/src/io/error/os_functions.rs:9:36
|
9 | pub(super) unsafe fn set_functions(f: &'static OsFunctions) {
| ^ help: if this is intentional, prefix it with an underscore: `_f`
|
= note: `-D unused-variables` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(unused_variables)]`
Thus clean it up.

Similar to the existing tests for other `cfg`s like `no_fp_fmt_parse`, add one for `no_io_statics`. This should prevent issues like the one in the parent commit. Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
We are refactoring from a large enum where the fields of the variants contain all the reflection info to a flat enum containing only the type kind (struct/bool/array etc). While we removed the fields of Struct, Enum and Union we forgot to take out the const eval code writing into those fields. That gave an ICE. This fixes that.

Rip out old solver coherence cc [#t-types/call-for-participation > rip out old solver coherence support](https://rust-lang.zulipchat.com/#narrow/channel/618216-t-types.2Fcall-for-participation/topic/rip.20out.20old.20solver.20coherence.20support/with/613938355) Probably best reviewed commit-by-commit with ignore-whitespace. rust-lang#160668 replaced the last remaining place where old solver was still used by default in coherence with new solver. This PR removes code that was only used during coherence by the old solver, so now new-solver coherence is the *only* way to do coherence. So we don't confuse users, passing `-Znext-solver=coherence` and `=no` now do the exact same thing. We also remove tracking intercrate ambiguity causes, since afaict the new solver uses a completely different path. Everything else is either removing code that is now unreachable, or removing a condition that is now always true. r? lcnr
…ttribute, r=bushrat011899 Add documentation for the `no_main` and `repr` attributes Part of rust-lang#157604. This PR documents `no_main` and `repr` attributes in `library/core/src/attribute_docs.rs` with some examples. Tested with: `./x doc`
…fo, r=oli-obk reflection: fix ICE when TypeId::info called on ADT We are refactoring from a large enum where the fields of the variants contain all the reflection info to a flat enum containing only the type kind (struct/bool/array etc). While we removed the fields of Struct, Enum and Union we forgot to take out the const eval code writing into those fields. That gave an ICE. This fixes that.

If the signature is preferred to be exactly the same one as the `os_functions_atomic.rs` one, then we could `allow` it instead.
…, r=traviscross Make the tracking issue template better suited for experiments The lang team's experiment docs say to create a tracking issue, but the tracking issue template isn't well suited for features that lack an RFC. These are minor changes that should streamline the process. Thanks to @diondokter for pointing out how these could be improved. r? lang-ops
… r=RalfJung Avoid long iterator chain in all_rust_features This chain creates an absolute monster type that clutters my cachegrind diffs :) This should make it simpler. I believe we've also seen `chain` to optimize poorly, but I don't think that's a concern here. It might also compile faster, we know that deep types created with iterator chains tend to scale poorly.
