===========================

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.

- [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)

Cargo
-----
- [Packages can now inherit settings from the workspace so that
  the settings can be centralized in one place.]
  (rust-lang/cargo#10859) See
  [`workspace.package`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacepackage-table)
  and
  [`workspace.dependencies`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacedependencies-table)
  for more details on how to define these common settings.
- [Cargo commands can now accept multiple `--target` flags to build
  for multiple targets at once]
  (rust-lang/cargo#10766), and the
  [`build.target`](https://doc.rust-lang.org/nightly/cargo/reference/config.html#buildtarget)
  config option may now take an array of multiple targets.
- [The `--jobs` argument can now take a negative number to count
  backwards from the max CPUs.]
  (rust-lang/cargo#10844)
- [`cargo add` will now update `Cargo.lock`.]
  (rust-lang/cargo#10902)
- [Added](rust-lang/cargo#10838) the
  [`--crate-type`](https://doc.rust-lang.org/nightly/cargo/commands/cargo-rustc.html#option-cargo-rustc---crate-type)
  flag to `cargo rustc` to override the crate type.
- [Significantly improved the performance fetching git dependencies from GitHub
  when using a hash in the `rev` field.]
  (rust-lang/cargo#10079)

Misc
----
- [The `rust-analyzer` rustup component is now available on the stable channel.]
  (rust-lang/rust#98640)

Compatibility Notes
-------------------
- The minimum required versions for all `-linux-gnu` targets are
  now at least kernel 3.2 and glibc 2.17, for targets that previously
  supported older versions: [Increase the minimum linux-gnu
  versions](rust-lang/rust#95026)
- [Network primitives are now implemented with the ideal Rust
  layout, not the C system layout]
  (rust-lang/rust#78802). This can
  cause problems when transmuting the types.
- [Add assertion that `transmute_copy`'s `U` is not larger than `T`]
  (rust-lang/rust#98839)
- [A soundness bug in `BTreeMap` was fixed]
  (rust-lang/rust#99413) that allowed data
  it was borrowing to be dropped before the container.
- [The Drop behavior of C-like enums cast to ints has changed]
  (rust-lang/rust#96862). These are already
  discouraged by a compiler warning.
- [Relate late-bound closure lifetimes to parent fn in NLL]
  (rust-lang/rust#98835)
- [Errors at const-eval time are now in future incompatibility reports]
  (rust-lang/rust#97743)
- On the `thumbv6m-none-eabi` target, some incorrect `asm!` statements
  were erroneously accepted if they used the high registers (r8 to
  r14) as an input/output operand. [This is no longer accepted]
  (rust-lang/rust#99155).
- [`impl Trait` was accidentally accepted as the associated type
  value of return-position `impl Trait`]
  (rust-lang/rust#97346), without
  fulfilling all the trait bounds of that associated type, as long
  as the hidden type satisfies said bounds. This has been fixed.

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- Windows builds now use profile-guided optimization, providing
  10-20% improvements to compiler performance: [Utilize PGO for
  windows x64 rustc dist builds]
  (rust-lang/rust#96978)
- [Stop keeping metadata in memory before writing it to disk]
  (rust-lang/rust#96544)
- [compiletest: strip debuginfo by default for mode=ui]
  (rust-lang/rust#98140)
- Many improvements to generated code for derives, including
  performance improvements:
  - [Don't use match-destructuring for derived ops on structs.]
    (rust-lang/rust#98446)
  - [Many small deriving cleanups]
    (rust-lang/rust#98741)
  - [More derive output improvements]
    (rust-lang/rust#98758)
  - [Clarify deriving code](rust-lang/rust#98915)
  - [Final derive output improvements]
    (rust-lang/rust#99046)
  - [Stop injecting `#[allow(unused_qualifications)]` in generated
    `derive` implementations](rust-lang/rust#99485)
  - [Improve `derive(Debug)`](rust-lang/rust#98190)
- [Bump to clap 3](rust-lang/rust#98213)
- [fully move dropck to mir](rust-lang/rust#98641)
- [Optimize `Vec::insert` for the case where `index == len`.]
  (rust-lang/rust#98755)
- [Convert rust-analyzer to an in-tree tool]
  (rust-lang/rust#99603)

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.)

  (https://doc.rust-lang.org/stable/std/ffi/type.c_ushort.html)

These APIs are now usable in const contexts:

- [`slice::from_raw_parts`]
  (https://doc.rust-lang.org/stable/core/slice/fn.from_raw_parts.html)

Cargo
-----
- [Packages can now inherit settings from the workspace so that
  the settings can be centralized in one place.]
  (rust-lang/cargo#10859) See
  [`workspace.package`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacepackage-table)
  and
  [`workspace.dependencies`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacedependencies-table)
  for more details on how to define these common settings.
- [Cargo commands can now accept multiple `--target` flags to build
  for multiple targets at once]
  (rust-lang/cargo#10766), and the
  [`build.target`](https://doc.rust-lang.org/nightly/cargo/reference/config.html#buildtarget)
  config option may now take an array of multiple targets.
- [The `--jobs` argument can now take a negative number to count
  backwards from the max CPUs.]
  (rust-lang/cargo#10844)
- [`cargo add` will now update `Cargo.lock`.]
  (rust-lang/cargo#10902)
- [Added](rust-lang/cargo#10838) the
  [`--crate-type`](https://doc.rust-lang.org/nightly/cargo/commands/cargo-rustc.html#option-cargo-rustc---crate-type)
  flag to `cargo rustc` to override the crate type.
- [Significantly improved the performance fetching git dependencies from GitHub
  when using a hash in the `rev` field.]
  (rust-lang/cargo#10079)

Misc
----
- [The `rust-analyzer` rustup component is now available on the stable channel.]
  (rust-lang/rust#98640)

Compatibility Notes
-------------------
- The minimum required versions for all `-linux-gnu` targets are
  now at least kernel 3.2 and glibc 2.17, for targets that previously
  supported older versions: [Increase the minimum linux-gnu
  versions](rust-lang/rust#95026)
- [Network primitives are now implemented with the ideal Rust
  layout, not the C system layout]
  (rust-lang/rust#78802). This can
  cause problems when transmuting the types.
- [Add assertion that `transmute_copy`'s `U` is not larger than `T`]
  (rust-lang/rust#98839)
- [A soundness bug in `BTreeMap` was fixed]
  (rust-lang/rust#99413) that allowed data
  it was borrowing to be dropped before the container.
- [The Drop behavior of C-like enums cast to ints has changed]
  (rust-lang/rust#96862). These are already
  discouraged by a compiler warning.
- [Relate late-bound closure lifetimes to parent fn in NLL]
  (rust-lang/rust#98835)
- [Errors at const-eval time are now in future incompatibility reports]
  (rust-lang/rust#97743)
- On the `thumbv6m-none-eabi` target, some incorrect `asm!` statements
  were erroneously accepted if they used the high registers (r8 to
  r14) as an input/output operand. [This is no longer accepted]
  (rust-lang/rust#99155).
- [`impl Trait` was accidentally accepted as the associated type
  value of return-position `impl Trait`]
  (rust-lang/rust#97346), without
  fulfilling all the trait bounds of that associated type, as long
  as the hidden type satisfies said bounds. This has been fixed.

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- Windows builds now use profile-guided optimization, providing
  10-20% improvements to compiler performance: [Utilize PGO for
  windows x64 rustc dist builds]
  (rust-lang/rust#96978)
- [Stop keeping metadata in memory before writing it to disk]
  (rust-lang/rust#96544)
- [compiletest: strip debuginfo by default for mode=ui]
  (rust-lang/rust#98140)
- Many improvements to generated code for derives, including
  performance improvements:
  - [Don't use match-destructuring for derived ops on structs.]
    (rust-lang/rust#98446)
  - [Many small deriving cleanups]
    (rust-lang/rust#98741)
  - [More derive output improvements]
    (rust-lang/rust#98758)
  - [Clarify deriving code](rust-lang/rust#98915)
  - [Final derive output improvements]
    (rust-lang/rust#99046)
  - [Stop injecting `#[allow(unused_qualifications)]` in generated
    `derive` implementations](rust-lang/rust#99485)
  - [Improve `derive(Debug)`](rust-lang/rust#98190)
- [Bump to clap 3](rust-lang/rust#98213)
- [fully move dropck to mir](rust-lang/rust#98641)
- [Optimize `Vec::insert` for the case where `index == len`.]
  (rust-lang/rust#98755)
- [Convert rust-analyzer to an in-tree tool]
  (rust-lang/rust#99603)
