Add target-specific NaN payloads for the missing tier 2 targets This PR adds target-specific NaN payloads for the remaining tier 2 targets: - `arm64ec`: This target is a mix of `x86_64` and `aarch64`, meaning as they both have no extra payloads `arm64ec` also has no extra payloads. - `loongarch64`: Per [LoongArch Reference Manual - Volume 1: Basic Architecture](https://github.com/loongson/LoongArch-Documentation/releases/download/2023.04.20/LoongArch-Vol1-v1.10-EN.pdf) section 3.1.1.3, LoongArch does quieting NaN propagation with the Rust preferred NaN as its default NaN, meaning it has no extra payloads. - `nvptx64`: Per [PTX ISA documentation](https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#floating-point-instructions) section 9.7.3 (and section 9.7.4 for `f16`), all payloads are possible. The documentation explicitly states that `f16` and `f32` operations result in an unspecified NaN payload, while for `f64` it states "NaN payloads are supported" without specifying how or what payload will be generated if there are no input NaNs. - `powerpc` and `powerpc64`: Per [Power Instruction Set Architecture](https://files.openpower.foundation/s/9izgC5Rogi5Ywmm/download/OPF_PowerISA_v3.1C.pdf) Book I section 4.3.2, PowerPC does quieting NaN propagation with the Rust preferred NaN being generated if no there are no input NaNs, meaning it has no extra payloads. - `s390x`: Per [IBM z/Architecture Principles of Operation](https://www.vm.ibm.com/library/other/22783213.pdf#page=965) page 9-3, s390x does quieting NaN propagation with the Rust's preferred NaN as its default NaN, meaning it has no extra payloads. Tracking issue: rust-lang#128288 cc `@RalfJung` `@rustbot` label +T-lang Also cc relevant target maintainers of tier 2 targets: - `arm64ec`: `@dpaoliello` - `loongarch64`: `@heiher` `@xiangzhai` `@zhaixiaojuan` `@xen0n` - `nvptx64`: `@RDambrosio016` `@kjetilkjeka` - `powerpc`: the only documented maintainer is `@BKPepe` for the tier 3 `powerpc-unknown-linux-muslspe`. - `powerpc64`: `@daltenty` `@gilamn5tr` `@Gelbpunkt` `@famfo` `@neuschaefer` - `s390x`: `@uweigand` `@cuviper`

…pes, r=fee1-dead,traviscross make abi_unsupported_vector_types a hard error Fixes rust-lang#116558 by completing the transition; see that issue for context. The lint was introduced with Rust 1.84 and this has been shown in cargo's future breakage reports since Rust 1.85, released 6 weeks ago, and so far we got 0 complaints by users. There's not even a backlink on the tracking issue. We did a [crater run](rust-lang#127731 (comment)) when the lint was originally added and found no breakage. So I don't think we need another crater run now, but I can do one if the team prefers that. rust-lang#131800 is done, so for most current targets (in particular, all tier 1 and tier 2 targets) we have the information to implement this check (modulo the targets where we don't properly support SIMD vectors yet, see the sub-issues of rust-lang#116558). If a new target gets added in the future, it will default to reject all SIMD vector types until proper information is added, which is the default we want. This will need approval by for `@rust-lang/lang.` Cc `@workingjubilee` `@veluca93`

…eyouxu Remove stray newline from post-merge report [Oops](rust-lang#140043 (comment)) :) r? jieyouxu

…Urgau Remove (now unused) #[rustc_macro_edition_2021] attribute Now that rust-lang#139114 has been merged, we no longer need the temporary hack (`#[rustc_macro_edition_2021]`) that we introduced in rust-lang#138717. Time to remove it.

replace broken links armv7-rtems-eabihf.md Hi team , i found broken link in `src/doc/rustc/src/platform-support/armv7-rtems-eabihf.md` and replace thanks
