I made a mistake testing #140772 only with rustup-toolchain-install-master which doesn't care about the manifests.

This means windows-gnullvm self-hosting will have to wait one more release, unless this change is backported to beta and a new beta release is made, which doesn't seem worth the trouble.

@bors r+

I'm going to go ahead and reject the backport since we don't normally backport features (and this is one). We should really figure out a way to make it much harder to miss updating this file though...

### Release Notes

<details>
<summary>rust-lang/rust (rust)</summary>

### [`v1.91.0`](https://github.com/rust-lang/rust/blob/HEAD/RELEASES.md#Version-1910-2025-10-30)

[Compare Source](rust-lang/rust@1.90.0...1.91.0)

\==========================

<a id="1.91.0-Language"></a>

## Language

- [Lower pattern bindings in the order they're written and base drop order on primary bindings' order](rust-lang/rust#143764)
- [Stabilize declaration of C-style variadic functions for `sysv64`, `win64`, `efiapi`, and `aapcs` ABIs](rust-lang/rust#144066).
  This brings these ABIs in line with the C ABI: variadic functions can be declared in extern blocks but not defined.
- [Add `dangling_pointers_from_locals` lint to warn against dangling pointers from local variables](rust-lang/rust#144322)
- [Upgrade `semicolon_in_expressions_from_macros` from warn to deny](rust-lang/rust#144369)
- [Stabilize LoongArch32 inline assembly](rust-lang/rust#144402)
- [Add warn-by-default `integer_to_ptr_transmutes` lint against integer-to-pointer transmutes](rust-lang/rust#144531)
- [Stabilize `sse4a` and `tbm` target features](rust-lang/rust#144542)
- [Add `target_env = "macabi"` and `target_env = "sim"` cfgs](rust-lang/rust#139451) as replacements for the `target_abi` cfgs with the same values.

<a id="1.91.0-Compiler"></a>

## Compiler

- [Don't warn on never-to-any `as` casts as unreachable](rust-lang/rust#144804)

<a id="1.91.0-Platform-Support"></a>

## Platform Support

- [Promote `aarch64-pc-windows-gnullvm` and `x86_64-pc-windows-gnullvm` to Tier 2 with host tools.](rust-lang/rust#143031)
  Note: llvm-tools and MSI installers are missing but will be added in future releases.
- [Promote `aarch64-pc-windows-msvc` to Tier 1](rust-lang/rust#145682)

Refer to Rust's [platform support page][platform-support-doc]
for more information on Rust's tiered platform support.

[platform-support-doc]: https://doc.rust-lang.org/rustc/platform-support.html

<a id="1.91.0-Libraries"></a>

## Libraries

- [Print thread ID in panic message](rust-lang/rust#115746)
- [Fix overly restrictive lifetime in `core::panic::Location::file` return type](rust-lang/rust#132087)
- [Guarantee parameter order for `_by()` variants of `min` / `max`/ `minmax` in `std::cmp`](rust-lang/rust#139357)
- [Document assumptions about `Clone` and `Eq` traits](rust-lang/rust#144330)
- [`std::thread`: Return error if setting thread stack size fails](rust-lang/rust#144210)
  This used to panic within the standard library.

## Cargo

- 🎉 Stabilize `build.build-dir`.
  This config sets the directory where intermediate build artifacts are stored.
  These artifacts are produced by Cargo and rustc during the build process.
  End users usually won't need to interact with them, and the layout inside
  `build-dir` is an implementation detail that may change without notice.
  ([config doc](https://doc.rust-lang.org/stable/cargo/reference/config.html#buildbuild-dir))
  ([build cache doc](https://doc.rust-lang.org/stable/cargo/reference/build-cache.html))
  [#&#8203;15833](rust-lang/cargo#15833)
  [#&#8203;15840](rust-lang/cargo#15840)
- The `--target` flag and the `build.target` configuration can now take literal
  `"host-tuple"` string, which will internally be substituted by the host
  machine's target triple.

<a id="1.91.0-Rustdoc"></a>

## Rustdoc

- [In search results, rank doc aliases lower than non-alias items with the same name](rust-lang/rust#145100)
- [Raw pointers now work in type-based search like references](rust-lang/rust#145731). This means you can now search for things like `*const u8 ->`, and additionally functions that take or return raw pointers will now display their signature properly in search results.

## Compatibility Notes

Cargo compatibility notes:

- `cargo publish` no longer keeps `.crate` tarballs as final build artifacts
  when `build.build-dir` is set. These tarballs were previously included due to
  an oversight and are now treated as intermediate artifacts.
  To get `.crate` tarballs as final artifacts, use `cargo package`.
  In a future version, this change will apply regardless of `build.build-dir`.
  [#&#8203;15910](rust-lang/cargo#15910)
- Adjust Cargo messages to match rustc diagnostic style.
  This changes some of the terminal colors used by Cargo messages.
  [#&#8203;15928](rust-lang/cargo#15928)
- Tools and projects relying on the
  [internal details of Cargo's `build-dir`](https://doc.rust-lang.org/cargo/reference/build-cache.html)
  may not work for users changing their `build-dir` layout.
  For those doing so, we'd recommend proactively testing these cases
  particularly as we are considering changing the default location of the `build-dir` in the future
  ([cargo#16147](rust-lang/cargo#16147)).
  If you can't migrate off of Cargo's internal details,
  we'd like to learn more about your use case as we prepare to change the layout of the `build-dir`
  ([cargo#15010](rust-lang/cargo#15010)).

wip-sync pushed a commit to NetBSD/pkgsrc-wip that referenced this pull request Nov 5, 2025
Pkgsrc changes:
 * Adjust patches to adapt to upstream changes and new versions.
 * assosicated checksums
 * Add a workaround for LLVM mis-using -isystem.  Reported upstream
   at llvm/llvm-project#166420

Noteable failures at the time of commit:
 * The cross-build for armv6 fails, reported upstream at
   rust-lang/rust#148464
 * The cross-build for powerpc fails, reported upstream at
   rust-lang/rust#148497
   This is R_PPC_PLTREL24 which now has insufficient range.
   Asked for recpie for directing the rust code generator to cope.

Upstream changes relative to 1.90.0:

Version 1.91.0 (2025-10-30)
==========================

Language
--------

- [Lower pattern bindings in the order they're written and base
  drop order on primary bindings' order]
  (rust-lang/rust#143764)
- [Stabilize declaration of C-style variadic functions for `sysv64`,
  `win64`, `efiapi`, and `aapcs` ABIs]
  (rust-lang/rust#144066).  This brings
  these ABIs in line with the C ABI: variadic functions can be
  declared in extern blocks but not defined.
- [Add `dangling_pointers_from_locals` lint to warn against dangling
  pointers from local variables]
  (rust-lang/rust#144322)
- [Upgrade `semicolon_in_expressions_from_macros` from warn to deny]
  (rust-lang/rust#144369)
- [Stabilize LoongArch32 inline assembly]
  (rust-lang/rust#144402)
- [Add warn-by-default `integer_to_ptr_transmutes` lint against
  integer-to-pointer transmutes]
  (rust-lang/rust#144531)
- [Stabilize `sse4a` and `tbm` target features]
  (rust-lang/rust#144542)
- [Add `target_env = "macabi"` and `target_env = "sim"` cfgs]
  (rust-lang/rust#139451) as replacements
  for the `target_abi` cfgs with the same values.

Compiler
--------

- [Don't warn on never-to-any `as` casts as unreachable]
  (rust-lang/rust#144804)

Platform Support
----------------

- [Promote `aarch64-pc-windows-gnullvm` and `x86_64-pc-windows-gnullvm`
  to Tier 2 with host tools.]
  (rust-lang/rust#143031) Note: llvm-tools
  and MSI installers are missing but will be added in future
  releases.
- [Promote `aarch64-pc-windows-msvc` to Tier 1]
  (rust-lang/rust#145682)

Refer to Rust's [platform support page][platform-support-doc]
for more information on Rust's tiered platform support.

[platform-support-doc]: https://doc.rust-lang.org/rustc/platform-support.html

Libraries
---------

- [Print thread ID in panic message]
  (rust-lang/rust#115746)
- [Fix overly restrictive lifetime in `core::panic::Location::file` return type]
  (rust-lang/rust#132087)
- [Guarantee parameter order for `_by()` variants of `min` / `max`/
  `minmax` in `std::cmp`] (rust-lang/rust#139357)
- [Document assumptions about `Clone` and `Eq` traits]
  (rust-lang/rust#144330)
- [`std::thread`: Return error if setting thread stack size fails]
  (rust-lang/rust#144210)
  This used to panic within the standard library.

Cargo
-----

- 🎉 Stabilize `build.build-dir`.
  This config sets the directory where intermediate build artifacts are stored.
  These artifacts are produced by Cargo and rustc during the build process.
  End users usually won't need to interact with them, and the layout inside
  `build-dir` is an implementation detail that may change without notice.
  ([config doc]
  (https://doc.rust-lang.org/stable/cargo/reference/config.html#buildbuild-dir))
  ([build cache doc]
  (https://doc.rust-lang.org/stable/cargo/reference/build-cache.html))
  [#15833](rust-lang/cargo#15833)
  [#15840](rust-lang/cargo#15840)
- The `--target` flag and the `build.target` configuration can now take literal
  `"host-tuple"` string, which will internally be substituted by the host
  machine's target triple.

  [#16003](rust-lang/cargo#16003)
  [#16032](rust-lang/cargo#16032)

Rustdoc
-----

- [In search results, rank doc aliases lower than non-alias items
  with the same name](rust-lang/rust#145100)
- [Raw pointers now work in type-based search like references]
  (rust-lang/rust#145731). This means you
  can now search for things like `*const u8 ->`, and additionally
  functions that take or return raw pointers will now display their
  signature properly in search results.

Compatibility Notes
-------------------

- [Always require coroutine captures to be drop-live]
  (rust-lang/rust#144156)
- [Apple: Always pass SDK root when linking with `cc`, and pass it
  via `SDKROOT` env var]
  (rust-lang/rust#131477). This should fix
  linking issues with `rustc` running inside Xcode. Libraries in
  `/usr/local/lib` may no longer be linked automatically, if you
  develop or use a crate that relies on this, you should explicitly
  set `cargo::rustc-link-search=/usr/local/lib` in a `build.rs`
  script.
- [Relaxed bounds in associated type bound position like in
  `TraitRef<AssocTy: ?Sized>` are now correctly forbidden]
  (rust-lang/rust#135331)
- [Add unstable `#[sanitize(xyz = "on|off")]` built-in attribute
  that shadows procedural macros with the same name]
  (rust-lang/rust#142681)
- [Fix the drop checker being more permissive for bindings declared
  with let-else] (rust-lang/rust#143028)
- [Be more strict when parsing attributes, erroring on many invalid attributes]
  (rust-lang/rust#144689)
    - [Error on invalid `#[should_panic]` attributes]
      (rust-lang/rust#143808)
    - [Error on invalid `#[link]` attributes]
      (rust-lang/rust#143193)
- [Mark all deprecation lints in name resolution as deny-by-default
  and also report in dependencies]
  (rust-lang/rust#143929)
- The lint `semicolon_in_expressions_from_macros`, for `macro_rules!`
  macros in expression position that expand to end in a semicolon
  (`;`), is now deny-by-default. It was already warn-by-default,
  and a future compatibility warning (FCW) that warned even in

  (rust-lang/rust#144386)
- [Start reporting future breakage for `ill_formed_attribute_input`
  in dependencies] (rust-lang/rust#144544)
- [Restrict the scope of temporaries created by the macros `pin!`,
  `format_args!`, `write!`, and `writeln!` in `if let` scrutinees in
  Rust Edition 2024.]
  (rust-lang/rust#145342) This applies
  [Rust Edition 2024's `if let` temporary scope rules]
  (https://doc.rust-lang.org/edition-guide/rust-2024/temporary-if-let-scope.html)
  to these temporaries, which previously could live past the `if`
  expression regardless of Edition.
- [Invalid numeric literal suffixes in tuple indexing, tuple struct
  indexing, and struct field name positions are now correctly rejected]
  (rust-lang/rust#145463)
- [Closures marked with the keyword `static` are now syntactically invalid]
  (rust-lang/rust#145604)
- [Shebangs inside `--cfg` and `--check-cfg` arguments are no longer allowed]
  (rust-lang/rust#146211)
- [Add future incompatibility lint for temporary lifetime shortening
  in Rust 1.92] (rust-lang/rust#147056)

Cargo compatibility notes:

- `cargo publish` no longer keeps `.crate` tarballs as final build artifacts
  when `build.build-dir` is set. These tarballs were previously included due to
  an oversight and are now treated as intermediate artifacts.
  To get `.crate` tarballs as final artifacts, use `cargo package`.
  In a future version, this change will apply regardless of `build.build-dir`.
  [#15910](rust-lang/cargo#15910)
