- Address Call for Testing review feedback - Address Affiliated work review feedback - Drop "stabilization is easy" part - Fix broken feature gate examples - Elaborate on stabilization report summarization aspects - Recommend waiting a bit for team nominations - Make Stabilization Template markdown copy friendly - Register stabilization report template - Drop unfinished sentence - Clarify stabilization report template is for language features - Add test coverage elaboration - Add UB checks / opt question - Amend test coverage explanation - Mention OSS nightly users
Let's revise both the new content in this PR as well as the remaining text in the relevant chapters so as to better describe our current processes related to language features and their stabilizations. For the new stabilization report template, based on reviewing its early use and well as reviewing earlier stabilization reports, we've revised it editorially and added questions designed to capture additional details to which we commonly want people to speak.

Raw Pointers are Constant PatKinds too
raw pointers can be matched on with a const pattern:
```rust
const FOO: *const u8 = core::ptr::null();
fn foo(a: *const u8) {
match a {
FOO => (),
_ => todo!(),
}
}
```
as far as I can tell this is represented with a `PatKind::Constant`: https://github.com/rust-lang/rust/blob/master/compiler/rustc_mir_build/src/thir/pattern/const_to_pat.rs#L333-L337
fixed typo chunks->as_chunks Fixes rust-lang#144555 info-: fix typo chunks -> as_chunks This now take us to as_chunks page when clicking on as_chunks link and not to chunks . Thanks .
…rors Ensure correct aligement of rustc_hir::Lifetime on platforms with lower default alignments. The compiler relies on `hir::Lifetime` being aligned to at least 4 bytes(for the purposes of pointer tagging). However, on some systems(like m68k) with lower alignment requirements(eg. usize / u32 aligned to 2 bytes),`hir::Lifetime` will be aligned to only 2 bytes. This causes the compilation to fail on those systems - a const assert in the compiler fails. This PR makes the aligement requriement of hir::Lifetime explict. This has no effect on platforms where that already is the case(repr align can only raise alignment), but ensures the alignment will stay correct no matter what.

coverage: Regression test for "function name is empty" bug Regression test for rust-lang#141577, which was triggered by rust-lang#144298. The bug was triggered by a particular usage of the `?` try operator in a proc-macro expansion. Thanks to lqd for the minimization at rust-lang#144571 (comment). --- I have manually verified that reverting the relevant follow-up fixes (rust-lang#144480 and rust-lang#144530) causes this test to reproduce the bug: ```sh git revert -m1 8aa3d41 c462895 ``` --- r? compiler
