Per #112156, using `&` in `format!` may cause a small perf delay, so I tried to clean up one module at a time format usage. This PR includes a few removals of the ref in format (they do compile locally without the ref), as well as a few format inlining for consistency.

This came from x86_64-unknown-none and doesn't make sense here.
This option guards the logic of writing long type names in files and instead using short forms in error messages in rustc_middle/ty/error behind a flag. The main motivation for this change is to disable this behaviour when running ui tests. This logic can be triggered by running tests in a directory that has a long enough path, e.g. /my/very-long-path/where/rust-codebase/exists/ This means ui tests can fail depending on how long the path to their file is. Some ui tests actually rely on this behaviour for their assertions, so for those we enable the flag manually.
…n-errors-in-gcc, r=davidtwco Reuse `codegen_ssa` monomorphization errors in `codegen_gcc` Removes monomorphization errors duplication by reusing the ones defined in `codegen_ssa`. Also updates `expected_simd` errors usage in `codegen_gcc` by assuming we want to treat those parameters as translatable. See rust-lang/rust@7a888fb
…ion loop This section name is always constant for a given target, but obtaining it from LLVM requires a few intermediate allocations. There's no need to do so repeatedly from inside a per-function loop.
Add `riscv64gc-unknown-hermit` target This PR adds the new `riscv64gc-unknown-hermit` target, initially created by `@simonschoening,` a 64-bit RISC-V target for the [Hermit] unikernel project. Furthermore, this cleans up the existing Hermit targets and adds a platform support documentation page for _all_ Hermit targets and goes through the new tier 3 target policy process: [Hermit]: https://github.com/hermitcore ## Tier 3 target policy > - A tier 3 target must have a designated developer or developers (the "target > maintainers") on record to be CCed when issues arise regarding the target. > (The mechanism to track and CC such developers may evolve over time.) `@stlankes` as the Hermit project lead and I will be the target maintainers. > - Targets must use naming consistent with any existing targets; for instance, a > target for the same CPU or OS as an existing Rust target should use the same > name for that CPU or OS. Targets should normally use the same names and > naming conventions as used elsewhere in the broader ecosystem beyond Rust > (such as in other toolchains), unless they have a very good reason to > diverge. Changing the name of a target can be highly disruptive, especially > once the target reaches a higher tier, so getting the name right is important > even for a tier 3 target. > - Target names should not introduce undue confusion or ambiguity unless > absolutely necessary to maintain ecosystem compatibility. For example, if > the name of the target makes people extremely likely to form incorrect > beliefs about what it targets, the name should be changed or augmented to > disambiguate it. > - If possible, use only letters, numbers, dashes and underscores for the name. > Periods (`.`) are known to cause issues in Cargo. The target name `riscv64gc-unknown-hermit` was derived from the existing `x86_64-unknown-hermit` and `aarch64-unknown-hermit` targets. > - Tier 3 targets may have unusual requirements to build or use, but must not > create legal issues or impose onerous legal terms for the Rust project or for > Rust developers or users. > - The target must not introduce license incompatibilities. > - Anything added to the Rust repository must be under the standard Rust > license (`MIT OR Apache-2.0`). > - The target must not cause the Rust tools or libraries built for any other > host (even when supporting cross-compilation to the target) to depend > on any new dependency less permissive than the Rust licensing policy. This > applies whether the dependency is a Rust crate that would require adding > new license exceptions (as specified by the `tidy` tool in the > rust-lang/rust repository), or whether the dependency is a native library > or binary. In other words, the introduction of the target must not cause a > user installing or running a version of Rust or the Rust tools to be > subject to any new license requirements. > - Compiling, linking, and emitting functional binaries, libraries, or other > code for the target (whether hosted on the target itself or cross-compiling > from another target) must not depend on proprietary (non-FOSS) libraries. > Host tools built for the target itself may depend on the ordinary runtime > libraries supplied by the platform and commonly used by other applications > built for the target, but those libraries must not be required for code > generation for the target; cross-compilation to the target must not require > such libraries at all. For instance, `rustc` built for the target may > depend on a common proprietary C runtime library or console output library, > but must not depend on a proprietary code generation library or code > optimization library. Rust's license permits such combinations, but the > Rust project has no interest in maintaining such combinations within the > scope of Rust itself, even at tier 3. > - "onerous" here is an intentionally subjective term. At a minimum, "onerous" > legal/licensing terms include but are *not* limited to: non-disclosure > requirements, non-compete requirements, contributor license agreements > (CLAs) or equivalent, "non-commercial"/"research-only"/etc terms, > requirements conditional on the employer or employment of any particular > Rust developers, revocable terms, any requirements that create liability > for the Rust project or its developers or users, or any requirements that > adversely affect the livelihood or prospects of the Rust project or its > developers or users.

`expr_to_string` allows raw strings through so this code should be expected to handle those. Signed-off-by: David Wood <david@davidtw.co>
The status quo is highly confusing, since the overlap is not apparent, and specialization is not a feature of Rust. This addresses #87545; I'm not certain if it closes it, since that issue might also be trackign a *general* solution for hiding specializing impls automatically.
During borrowck, the `MultiSpan` from a buffered diagnostic is cloned and used to emit a delayed bug indicating a diagnostic was buffered - when the buffered diagnostic is translated, then the cloned `MultiSpan` may contain labels which can only render with the diagnostic's arguments, but the delayed bug being emitted won't have those arguments. Adds a function which clones `MultiSpan` without also cloning the contained labels, and use this function when creating the buffered diagnostic delayed bug.

…ilee Regression test `println!()` panic message on `ErrorKind::BrokenPipe` No existing test (that I could find) failed if the `panic!()` of the `println!()` family of functions was removed, or if its message was changed: https://github.com/rust-lang/rust/blob/104f4300cfddbd956e32820ef202a732f06ec848/library/std/src/io/stdio.rs#L1007-L1009 So add such a test. This is in preparation of adding a hint about the existence of [`unix_sigpipe`](rust-lang/rust#97889) if that is the reason for the panic. Even if we don't end up adding a hint, this is still a sensible test to have, I think. `@rustbot` label +A-testsuite +A-io +T-libs +O-unix

Add documentation on v0 symbol mangling. This adds official documentation for the v0 symbol mangling format, migrating the documentation from [RFC 2603](https://rust-lang.github.io/rfcs/2603-rust-symbol-name-mangling-v0.html). The format was originally stabilized as the `-C symbol-mangling-version` option, but the specifics were not stabilized (per rust-lang/rust#90128 (comment)). Per the discussion at rust-lang/rust#93661 (comment) this adds those specifics as an official description of the format. cc #89917

Diagnostic namespace This PR implements the basic infrastructure for accepting the `#[diagnostic]` attribute tool namespace as specified in rust-lang/rfcs#3368. Note: This RFC is not merged yet, but it seems like it will be accepted soon. I open this PR early on to get feedback on the actual implementation as soon as possible. This hopefully enables getting at least the diagnostic namespace to stable rust "soon", so that crates do not need to bump their MSRV if we stabilize actual attributes in this namespace. This PR only adds infrastructure accept attributes from this namespace, it does not add any specific attribute. Therefore the compiler will emit a lint warning for each attribute that's actually used. This namespace is added behind a feature flag, so it will be only available on a nightly compiler for now. cc `@estebank` as they've supported me in planing, specifying and implementing this feature.
