When encountering a move conflict, on an expression that is `!Copy` passed as an argument to an `fn` that is `impl AsRef`, suggest borrowing the expression. ``` error[E0382]: use of moved value: `bar` --> f204.rs:14:15 | 12 | let bar = Bar; | --- move occurs because `bar` has type `Bar`, which does not implement the `Copy` trait 13 | foo(bar); | --- value moved here 14 | let baa = bar; | ^^^ value used here after move | help: borrow the value to avoid moving it | 13 | foo(&bar); | + ``` Fix rust-lang#41708
That would give it alignment of 1 which is ABI-incompatible with its C definition.
On s390x, every use of the f16 data type will currently ICE due to llvm/llvm-project#50374, causing doctest failures on the platform. Most doctests were already restricted to certain platforms, so fix this by likewise restricting the remaining five.
…ggestions as well This commit changes the error reporting mechanism for not implemented traits to skip impl marked as `#[diagnostic::do_not_recommend]` in the help part of the error message ("the following other types implement trait `Foo`:"). The main use case here is to allow crate authors to skip non-meaningful confusing suggestions. A common example for this are fully generic impls on tuples. 
Name this something that is less confusable with an atomic consume API for `{Lazy,Once}Lock`. 
Remove the unstable `extern "wasm"` ABI (`wasm_abi` feature tracked in rust-lang#83788). As discussed in rust-lang#127513 (comment) and following, this ABI is a failed experiment that did not end up being used for anything. Keeping support for this ABI in LLVM 19 would require us to switch wasm targets to the `experimental-mv` ABI, which we do not want to do. It should be noted that `Abi::Wasm` was internally used for two things: The `-Z wasm-c-abi=legacy` ABI that is still used by default on some wasm targets, and the `extern "wasm"` ABI. Despite both being `Abi::Wasm` internally, they were not the same. An explicit `extern "wasm"` additionally enabled the `+multivalue` feature. I've opted to remove `Abi::Wasm` in this patch entirely, instead of keeping it as an ABI with only internal usage. Both `-Z wasm-c-abi` variants are now treated as part of the normal C ABI, just with different different treatment in adjust_for_foreign_abi.

…hpratt Don't mark `DEBUG_EVENT` struct as `repr(packed)` That would give it alignment of 1 which is ABI-incompatible with its C definition.
…oss35 core: Limit remaining f16 doctests to x86_64 linux On s390x, every use of the f16 data type will currently ICE due to llvm/llvm-project#50374, causing doctest failures on the platform.

…y, r=lcnr Make sure that labels are defined after the primary span in diagnostics Putting a `#[label]` before a `#[primary_span]` results in that label being overwritten, due to the semantics of `Diagnostic::span` and the fact that labels are stored in the `MultiSpan` of the diagnostic. This isn't possible to fix in general, since a lot of code actually *relies* in this overwriting behavior (e.g. `rustc_on_unimplemented`). However, it's useful to enforce this for derive-diagnostics, since this is certainly never what you intend to do in a derived diagnostic, where all the fields are meaningful parts of the diagnostic being rendered. This only matters for `#[label]`, since those are the ones stored in the `MultiSpan` of the error. We could also make this "just work" by sorting the attrs or processing the primary span attr first, however I think it's kinda pointless to do. There was 1 case where this mattered, but we literally didn't have a test exercising that diagnostic 🙃
