It looks like this also needs to update:
* Platform support list: https://github.com/rust-lang/rust/blob/c3d7fb398569407350abe044e786bc7890c90397/src/doc/rustc/src/platform-support.md#L308 * I suspect rustup list needs to get updated: https://github.com/rust-lang/rust/blob/master/src/tools/build-manifest/src/main.rsr=me with those done
I plan to promote it after adding CI. I would be happy to combine both CI and promote together. Thanks.
This PR changes how LLVM is built. Consider updating src/bootstrap/download-ci-llvm-stamp.

This MR contains the following updates:
| Package | Update | Change |
|---|---|---|
| rust | minor | 1.80.1 -> 1.81.0 |
MR created with the help of el-capitano/tools/renovate-bot.
Proposed changes to behavior should be submitted there as MRs.
Release Notes
rust-lang/rust (rust)
v1.81.0
==========================
Language
- Abort on uncaught panics in
extern "C"functions. - Fix ambiguous cases of multiple
&in elided self lifetimes. - Stabilize
#[expect]for lints (RFC 2383), like#[allow]with a warning if the lint is not fulfilled. - Change method resolution to constrain hidden types instead of rejecting method candidates.
- Bump
elided_lifetimes_in_associated_constantto deny. offset_from: always allow pointers to point to the same address.- Allow constraining opaque types during subtyping in the trait system.
- Allow constraining opaque types during various unsizing casts.
- Deny keyword lifetimes pre-expansion.
Compiler
- Make casts of pointers to trait objects stricter.
- Check alias args for well-formedness even if they have escaping bound vars.
- Deprecate no-op codegen option
-Cinline-threshold=.... - Re-implement a type-size based limit.
- Properly account for alignment in
transmutesize checks. - Remove the
box_pointerslint. - Ensure the interpreter checks bool/char for validity when they are used in a cast.
- Improve coverage instrumentation for functions containing nested items.
- Target changes:
- Add Tier 3
no_stdXtensa targets:xtensa-esp32-none-elf,xtensa-esp32s2-none-elf,xtensa-esp32s3-none-elf - Add Tier 3
stdXtensa targets:xtensa-esp32-espidf,xtensa-esp32s2-espidf,xtensa-esp32s3-espidf - Add Tier 3 i686 Redox OS target:
i686-unknown-redox - Promote
arm64ec-pc-windows-msvcto Tier 2. - Promote
loongarch64-unknown-linux-muslto Tier 2 with host tools. - Enable full tools and profiler for LoongArch Linux targets.
- Unconditionally warn on usage of
wasm32-wasi. (see compatibility note below) - Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support.
- Add Tier 3
Libraries
- Split core's
PanicInfoand std'sPanicInfo. (see compatibility note below) - Generalize
{Rc,Arc}::make_mut()to unsized types. - Replace sort implementations with stable
driftsortand unstableipnsort. Allslice::sort*andslice::select_nth*methods are expected to see significant performance improvements. See the research project for more details. - Document behavior of
create_dir_allwith respect to empty paths. - Fix interleaved output in the default panic hook when multiple threads panic simultaneously.
Stabilized APIs
core::errorhint::assert_uncheckedfs::existsAtomicBool::fetch_notDuration::abs_diffIoSlice::advanceIoSlice::advance_slicesIoSliceMut::advanceIoSliceMut::advance_slicesPanicHookInfoPanicInfo::messagePanicMessage
These APIs are now stable in const contexts:
char::from_u32_unchecked(function)char::from_u32_unchecked(method)CStr::count_bytesCStr::from_ptr
Cargo
- Generated
.cargo_vcs_info.jsonis always included, even when--allow-dirtyis passed. - Disallow
package.license-fileandpackage.readmepointing to non-existent files during packaging. - Disallow passing
--release/--debugflag along with the--profileflag. - Remove
lib.pluginkey support inCargo.toml. Rust plugin support has been deprecated for four years and was removed in 1.75.0.
Compatibility Notes
Usage of the
wasm32-wasitarget will now issue a compiler warning and request users switch to thewasm32-wasip1target instead. Both targets are the same,wasm32-wasiis only being renamed, and this change to the WASI target is being done to enable removingwasm32-wasiin January 2025.We have renamed
std::panic::PanicInfotostd::panic::PanicHookInfo. The old name will continue to work as an alias, but will result in a deprecation warning starting in Rust 1.82.0.core::panic::PanicInfowill remain unchanged, however, as this is now a different type.The reason is that these types have different roles:
std::panic::PanicHookInfois the argument to the panic hook in std context (where panics can have an arbitrary payload), whilecore::panic::PanicInfois the argument to the#[panic_handler]in no_std context (where panics always carry a formatted message). Separating these types allows us to add more useful methods to these types, such asstd::panic::PanicHookInfo::payload_as_str()andcore::panic::PanicInfo::message().The new sort implementations may panic if a type's implementation of
Ord(or the given comparison function) does not implement a total order as the trait requires.Ord's supertraits (PartialOrd,Eq, andPartialEq) must also be consistent. The previous implementations would not "notice" any problem, but the new implementations have a good chance of detecting inconsistencies, throwing a panic rather than returning knowingly unsorted data.
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.

Both targets are the same,wasm32-wasiis only being renamed, and this [change to the WASI target] (https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets.html) is being done to enable removingwasm32-wasiin January 2025.We have renamed
std::panic::PanicInfotostd::panic::PanicHookInfo. The old name will continue to work as an alias, but will result in a deprecation warning starting in Rust 1.82.0.core::panic::PanicInfowill remain unchanged, however, as this is now a different type.The reason is that these types have different roles:
std::panic::PanicHookInfois the argument to the panic hook in std context (where panics can have an arbitrary payload), whilecore::panic::PanicInfois the argument to the#[panic_handler]in no_std context (where panics always carry a formatted message). Separating these types allows us to add more useful methods to these types, such asstd::panic::PanicHookInfo::payload_as_str()andcore::panic::PanicInfo::message().The new sort implementations may panic if a type's implementation of
Ord(or the given comparison function) does not implement a total order as the trait requires.Ord's supertraits (PartialOrd,Eq, andPartialEq) must also be consistent. The previous implementations would not "notice" any problem, but the new implementations have a good chance of detecting inconsistencies, throwing a panic rather than returning knowingly unsorted data.[In very rare cases, a change in the internal evaluation order of the trait solver may result in new fatal overflow errors.] (rust-lang/rust#126128)
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.
- [Add a Rust-for Linux
autoCI job to check kernel builds.] (rust-lang/rust#125209)
netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this pull request
Pkgsrc changes:
- Adapt patches, apply to new vendored crates where needed.
- Back-port rust pull request 130110, "make dist vendoring configurable"
- Disable "dist vendoring", otherwise cargo would try to access the network during the build phase.
