rust: update to version 1.58.1.
Pkgsrc changes:
* Bump available bootstraps to 1.57.0.
* For some reason, the vendor/libc checksums don't need fixing.
* Bump required external LLVM to 12.0, according to upstream change log.
* Adapt the Darwin linker patch.
(For some reason I've not figured out yet, cargo is a lot more
verbose while building, echoes the rustc invocation.)
Upstream changes:
Version 1.58.1 (2022-01-19)
===========================
* Fix race condition in `std::fs::remove_dir_all` ([CVE-2022-21658])
* [Handle captured arguments in the `useless_format` Clippy lint][clippy/8295]
* [Move `non_send_fields_in_send_ty` Clippy lint to nursery][clippy/8075]
* [Fix wrong error message displayed when some imports are missing][91254]
* [Fix rustfmt not formatting generated files from stdin][92912]

Version 1.58.0 (2022-01-13)
==========================
Language
--------
- [Format strings can now capture arguments simply by writing
`{ident}` in the string.][90473] This works in all macros accepting
format strings. Support for this in `panic!` (`panic!("{ident}")`)
requires the 2021 edition; panic invocations in previous editions
that appear to be trying to use this will result in a warning lint
about not having the intended effect.
- [`*const T` pointers can now be dereferenced in const contexts.][89551]
- [The rules for when a generic struct implements `Unsize` have
been relaxed.][90417]
Compiler
--------
- [Add LLVM CFI support to the Rust compiler][89652]
- [Stabilize -Z strip as -C strip][90058]. Note that while release
builds already don't add debug symbols for the code you compile,
the compiled standard library that ships with Rust includes debug
symbols, so you may want to use the `strip` option to remove these
symbols to produce smaller release binaries. Note that this release
only includes support in rustc, not directly in cargo.
- [Add support for LLVM coverage mapping format versions 5 and 6][91207]
- [Emit LLVM optimization remarks when enabled with `-Cremark`][90833]
- [Update the minimum external LLVM to 12][90175]
- [Add `x86_64-unknown-none` at Tier 3*][89062]
- [Build musl dist artifacts with debuginfo enabled][90733]. When
building release binaries using musl, you may want to use the newly
stabilized strip option to remove these debug symbols, reducing
the size of your binaries.
- [Don't abort compilation after giving a lint error][87337]
- [Error messages point at the source of trait bound obligations
in more places][89580]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
Libraries
---------
- [All remaining functions in the standard library have `#[must_use]`
annotations where appropriate][89692], producing a warning when
ignoring their return value. This helps catch mistakes such as
expecting a function to mutate a value in place rather than return
a new value.
- [Paths are automatically canonicalized on Windows for operations
that support it][89174]
- [Re-enable debug checks for `copy` and `copy_nonoverlapping`][90041]
- [Implement `RefUnwindSafe` for `Rc<T>`][87467]
- [Make RSplit<T, P>: Clone not require T: Clone][90117]
- [Implement `Termination` for `Result<Infallible, E>`][88601].
This allows writing `fn main() -> Result<Infallible, ErrorType>`,
for a program whose successful exits never involve returning from
`main` (for instance, a program that calls `exit`, or that uses
`exec` to run another program).
Stabilized APIs
---------------
- [`Metadata::is_symlink`]
- [`Path::is_symlink`]
- [`{integer}::saturating_div`]
- [`Option::unwrap_unchecked`]
- [`Result::unwrap_unchecked`]
- [`Result::unwrap_err_unchecked`]
- [`NonZero{unsigned}::is_power_of_two`]
- [`File::options`]
These APIs are now usable in const contexts:
- [`Duration::new`]
- [`Duration::checked_add`]
- [`Duration::saturating_add`]
- [`Duration::checked_sub`]
- [`Duration::saturating_sub`]
- [`Duration::checked_mul`]
- [`Duration::saturating_mul`]
- [`Duration::checked_div`]
- [`MaybeUninit::as_ptr`]
- [`MaybeUninit::as_mut_ptr`]
- [`MaybeUninit::assume_init`]
- [`MaybeUninit::assume_init_ref`]
Cargo
-----
- [Add --message-format for install command][cargo/10107]
- [Warn when alias shadows external subcommand][cargo/10082]
Rustdoc
-------
- [Show all Deref implementations recursively in rustdoc][90183]
- [Use computed visibility in rustdoc][88447]
Compatibility Notes
-------------------
- [Try all stable method candidates first before trying unstable
ones][90329]. This change ensures that adding new nightly-only
methods to the Rust standard library will not break code invoking
methods of the same name from traits outside the standard library.
- Windows: [`std::process::Command` will no longer search the
current directory for executables.][87704]
- [All proc-macro backward-compatibility lints are now deny-by-default.][88041]
- [proc_macro: Append .0 to unsuffixed float if it would otherwise
become int token][90297]
- [Refactor weak symbols in std::sys::unix][90846]. This optimizes
accesses to glibc functions, by avoiding the use of dlopen. This
does not increase the [minimum expected version of
glibc](https://doc.rust-lang.org/nightly/rustc/platform-support.html).
However, software distributions that use symbol versions to detect
library dependencies, and which take weak symbols into account in
that analysis, may detect rust binaries as requiring newer versions
of glibc.
- [rustdoc now rejects some unexpected semicolons in doctests][91026]
Internal Changes
----------------
These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance
of rustc and related tools.
- [Implement coherence checks for negative trait impls][90104]
- [Add rustc lint, warning when iterating over hashmaps][89558]
- [Optimize live point computation][90491]
- [Enable verification for 1/32nd of queries loaded from disk][90361]
- [Implement version of normalize_erasing_regions that allows for
normalization failure][91255]
