And move passing it to the linker to the driver code.
This deduplicates some code between codegen backends and may in the future allow adding extra metadata that is only known at link time.
This test currently fails (as expected).

Reduce precedence of expressions that have an outer attr
Previously, `-Zunpretty=expanded` would expand this program as follows:
```rust
#![feature(stmt_expr_attributes)]
macro_rules! repro {
($e:expr) => {
#[allow(deprecated)] $e
};
}
#[derive(Default)]
struct Thing {
#[deprecated]
field: i32,
}
fn main() {
let thing = Thing::default();
let _ = repro!(thing).field;
}
```
```rs
#![feature(prelude_import)]
#![feature(stmt_expr_attributes)]
#[prelude_import]
use std::prelude::rust_2021::*;
#[macro_use]
extern crate std;
struct Thing {
#[deprecated]
field: i32,
}
#[automatically_derived]
impl ::core::default::Default for Thing {
#[inline]
fn default() -> Thing {
Thing { field: ::core::default::Default::default() }
}
}
fn main() {
let thing = Thing::default();
let _ = #[allow(deprecated)] thing.field;
}
```
This is not the correct expansion. The correct output would have `(#[allow(deprecated)] thing).field` with the attribute applying only to `thing`, not to `thing.field`.
…ork, r=workingjubilee,saethlin Move metadata object generation for dylibs to the linker code This deduplicates some code between codegen backends and may in the future allow adding extra metadata that is only known at link time. Prerequisite of rust-lang#96708.
… r=oli-obk,traviscross Report never type lints in dependencies This PR marks never type lints (`never_type_fallback_flowing_into_unsafe` & `dependency_on_unit_never_type_fallback`) to be included in cargo's reports / to be emitted when they happen in dependencies. This PR is based on rust-lang#141936 r? oli-obk

Apply ABI attributes on return types in `rustc_codegen_cranelift` - The [x86-64 System V ABI standard](https://gitlab.com/x86-psABIs/x86-64-ABI/-/jobs/artifacts/master/raw/x86-64-ABI/abi.pdf?job=build) doesn't sign/zero-extend integer arguments or return types. - But the de-facto standard as implemented by Clang and GCC is to sign/zero-extend arguments to 32 bits (but not return types). - Additionally, Apple targets [sign/zero-extend both arguments and return values to 32 bits](https://developer.apple.com/documentation/xcode/writing-64-bit-intel-code-for-apple-platforms#Pass-arguments-to-functions-correctly). - However, the `rustc_target` ABI adjustment code currently [unconditionally extends both arguments and return values to 32 bits](https://github.com/rust-lang/rust/blame/e703dff8fe220b78195c53478e83fb2f68d8499c/compiler/rustc_target/src/callconv/x86_64.rs#L240) on all targets. - This doesn't cause a miscompilation when compiling with LLVM as LLVM will ignore the `signext`/`zeroext` attribute when applied to return types on non-Apple x86-64 targets. - Cranelift, however, does not have a similar special case, requiring `rustc` to set the argument extension attribute correctly. - However, `rustc_codegen_cranelift` doesn't currently apply ABI attributes to return types at all, meaning `rustc_codegen_cranelift` will currently miscompile `i8`/`u8`/`i16`/`u16` returns on x86-64 Apple targets as those targets require sign/zero-extension of return types. This PR fixes the bug(s) by making the `rustc_target` x86-64 System V ABI only mark return types as sign/zero-extended on Apple platforms, while also making `rustc_codegen_cranelift` apply ABI attributes to return types. The RISC-V and s390x C ABIs also require sign/zero extension of return types, so this will fix those targets when building with `rustc_codegen_cranelift` too. r? `````@bjorn3`````

…mease Suggest adding semicolon in user code rather than macro impl details This PR tries to find the right span (by peeling expansion) so that the suggestion for adding a semicolon is suggested in user code rather than in the expanded code (in the example a macro impl).
