I can't find any dedicated tests that actually exercises the stability gating (via `-Z unstable-options`) of print requests, so here's a dedicated one. I coalesced `tests/ui/feature-gates/feature-gate-print-check-cfg.rs` into this test, because AFAICT that print request is not feature gated, but only `-Z unstable-options`-gated just like other unstable print requests.
… into helpers To avoid duplicating stability check logic and make the print request collection logic more straightforward.
…on,TargetSpecJson}` To correspond to their actual print request names, `target-spec-json` and `all-target-specs-json`, and for consistency with other print name <-> print kind mappings.
It's bitflags in practice, so an enum is unsound, as an enum must only have the described values. The x86_64 psABI declares it as a `typedef int _Unwind_Action`, which seems reasonable. I made a newtype first but that was more annoying than just a typedef. We don't really use this value for much other than a short check.
document capacity for ZST as example The main text already covers this, although it provides weaker guarantees, but I think an example in the right spot does not hurt. Fixes rust-lang#80747
doc all differences of ptr:copy(_nonoverlapping) with memcpy and memmove Fixes rust-lang#79430
…-cleanup, r=aDotInTheVoid refactor `notable_traits_button` to use iterator combinators instead of for loop ~Small cleanup. Use `Iterator::any` instead of `for` loop with `predicate = true;`. I think this makes the code more readable... and also has the additional benefit of short-circuiting the iterator when a notable trait is found (a `break` statement was missing in the `for` loop version, I think). Probably won't be significant enough to show on perf results, though.~ Three commits, each attempting to optimize `notable_trait_buttons` by a little bit.

Misc print request handling cleanups + a centralized test for print request stability gating
I was working on implementing `--print=supported-crate-types`, then I noticed some things that were mildly annoying me, so I pulled out these changes. In this PR:
- First commit adds a centralized test `tests/ui/print/stability.rs` that is responsible for exercising stability gating of the print requests.
- AFAICT we didn't have any test that systematically checks this.
- I coalesced `tests/ui/feature-gates/feature-gate-print-check-cfg.rs` (for `--print=check-cfg`) into this test too, since `--print=check-cfg` is only `-Z unstable-options`-gated like other unstable print requests, and is not additionally feature-gated. cc ``@Urgau`` in case you have any concerns.
- Second commit alphabetically sorts the `PrintKind` enum for consistency because the `PRINT_KINDS` list (using the enum) is *already* alphabetically sorted.
- Third commit pulls out two helpers:
1. A helper `check_print_request_stability` for checking stability of print requests and the diagnostics for using unstable print requests without `-Z unstable-options`, to avoid repeating the same logic over and over.
2. A helper `emit_unknown_print_request_help` for the unknown print request diagnostics to make print request collection control flow more obvious.
- Fourth commit renames `PrintKind::{TargetSpec,AllTargetSpecs}` to `PrintKind::{TargetSpecJson,AllTargetSpecsJson}` to better reflect their actual print names, `--print={target-spec-json,all-target-specs-json}`.

…, r=workingjubilee Make `_Unwind_Action` a type alias, not enum It's bitflags in practice, so an enum is unsound, as an enum must only have the described values. The x86_64 psABI declares it as a `typedef int _Unwind_Action`, which seems reasonable. I made a newtype first but that was more annoying than just a typedef. We don't really use this value for much other than a short check. I ran `x check library --target aarch64-unknown-linux-gnu,x86_64-pc-windows-gnu,x86_64-fortanix-unknown-sgx,x86_64-unknown-haiku,x86_64-unknown-fuchsi a,x86_64-unknown-freebsd,x86_64-unknown-dragonfly,x86_64-unknown-netbsd,x86_64-unknown-openbsd,x86_64-unknown-redox,riscv64-linux-android,armv7-unknown-freebsd` (and some more but they failed to build for other reasons :D) fixes rust-lang#138558 r? workingjubilee have fun
