Formerly -Zterminal-width, --terminal-width allows the user or build
tool to inform rustc of the width of the terminal so that diagnostics
can be truncated.

Pending agreement to stabilize, see tracking issue at #84673.

Looks like you need to add this option for rustdoc too - see

Update terminal-width flag.

The rustc flag `-Zterminal-width` has been stabilized as `--terminal-width` in rust-lang/rust#95635. This updates cargo to use the new flag so that tests will pass.

Tests won't pass until the next nightly is published in about 10 hours from now. I just wanted to post this to get ahead of the breaking change.

This doesn't stabilize in cargo because that will take more time, and this is needed to prevent CI from failing. Will continue the stabilization discussion at rust-lang/rust#84673.

rustdoc: Stabilize --diagnostic-width

This stabilizes the `--diagnostic-width` flag for rustdoc. This flag was stabilized in rustc in rust-lang#95635, but it isn't clear from the discussion there why it wasn't stabilized in rustdoc. I believe this flag works as expected, following the same behavior as rustc.

I'd like to stabilize this so that the same support can be stabilized in cargo, and it would help simplify things if both rustc and rustdoc supported it.

rust: update to version 1.64.0.
1e2f8a8 
Pkgsrc changes:
 * Add patch to fix vendor/kqueue issue (on 32-bit hosts)
 * Adjust other patches & line numbers
 * Version bumps & checksum changes.

Upstream changes:

Version 1.64.0 (2022-09-22)
===========================

Language
--------
- [Unions with mutable references or tuples of allowed types are
  now allowed](rust-lang/rust#97995)

- It is now considered valid to deallocate memory pointed to by a
  shared reference `&T` [if every byte in `T` is inside an
  `UnsafeCell`](rust-lang/rust#98017)

- Unused tuple struct fields are now warned against in an
  allow-by-default lint, [`unused_tuple_struct_fields`]
  (rust-lang/rust#95977), similar to the
  existing warning for unused struct fields. This lint will become
  warn-by-default in the future.

Compiler
--------
- [Add Nintendo Switch as tier 3 target]
  (rust-lang/rust#88991)
  - Refer to Rust's [platform support page][platform-support-doc] for more
    information on Rust's tiered platform support.
- [Only compile `#[used]` as llvm.compiler.used for ELF targets]
  (rust-lang/rust#93718)
- [Add the `--diagnostic-width` compiler flag to define the terminal width.]
  (rust-lang/rust#95635)
- [Add support for link-flavor `rust-lld` for iOS, tvOS and watchOS]
  (rust-lang/rust#98771)

Libraries
---------
- [Remove restrictions on compare-exchange memory ordering.]
  (rust-lang/rust#98383)
- You can now `write!` or `writeln!` into an `OsString`: [Implement

netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this pull request Nov 16, 2022
@he32
rust: update to version 1.64.0.
cc0843c 
Pkgsrc changes:
 * This package now contains rust-analyzer, so implicitly
   conflicts with that pkgsrc package.  The same goes for
   the rust-src package.
 * Add NetBSD/arm6 port
 * Add unfinished NetBSD/mipsel port
 * Revert the use of the internal LLVM,
   should now build with the new pkgsrc LLVM (15).
 * Add depndence on compat80 for sparc64 to fix the build
 * Adapt patches
 * Add CHECK_INTERPRETER_SKIP for a few (mostly unused) files.
   (A proper fix may come later.)

Upstream changes:

Version 1.64.0 (2022-09-22)
===========================

Language
--------
- [Unions with mutable references or tuples of allowed types are
  now allowed](rust-lang/rust#97995)

- It is now considered valid to deallocate memory pointed to by a
  shared reference `&T` [if every byte in `T` is inside an
  `UnsafeCell`](rust-lang/rust#98017)

- Unused tuple struct fields are now warned against in an
  allow-by-default lint, [`unused_tuple_struct_fields`]
  (rust-lang/rust#95977), similar to the
  existing warning for unused struct fields. This lint will become
  warn-by-default in the future.

Compiler
--------
- [Add Nintendo Switch as tier 3 target]
  (rust-lang/rust#88991)
  - Refer to Rust's [platform support page][platform-support-doc] for more
    information on Rust's tiered platform support.
- [Only compile `#[used]` as llvm.compiler.used for ELF targets]
  (rust-lang/rust#93718)
- [Add the `--diagnostic-width` compiler flag to define the terminal width.]
  (rust-lang/rust#95635)
- [Add support for link-flavor `rust-lld` for iOS, tvOS and watchOS]
  (rust-lang/rust#98771)

Libraries
---------
- [Remove restrictions on compare-exchange memory ordering.]
  (rust-lang/rust#98383)
- You can now `write!` or `writeln!` into an `OsString`: [Implement
  `fmt::Write` for `OsString`](rust-lang/rust#97915)
- [Make RwLockReadGuard covariant]
  (rust-lang/rust#96820)
- [Implement `FusedIterator` for `std::net::[Into]Incoming`]
  (rust-lang/rust#97300)
- [`impl<T: AsRawFd> AsRawFd for {Arc,Box}<T>`]
  (rust-lang/rust#97437)
- [`ptr::copy` and `ptr::swap` are doing untyped copies]
  (rust-lang/rust#97712)
- [Add cgroupv1 support to `available_parallelism`]
  (rust-lang/rust#97925)
- [Mitigate many incorrect uses of `mem::uninitialized`]
  (rust-lang/rust#99182)

Remove -Z diagnostic-width

This removes the `-Z diagnostic-width` option since it is ignored and does nothing. `-Z diagnostic-width` was stabilized as `--diagnostic-width` in rust-lang#95635. It is not entirely clear why the `-Z` flag was kept, but in part its final use was removed in rust-lang#102216, but the `-Z` flag itself was not removed.

This removes the `-Z diagnostic-width` option since it is ignored and does nothing. `-Z diagnostic-width` was stabilized as `--diagnostic-width` in rust-lang#95635. It is not entirely clear why the `-Z` flag was kept, but in part its final use was removed in rust-lang#102216, but the `-Z` flag itself was not removed.
