netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this pull request Oct 18, 2025
Pkgsrc changes: * Disable the build of NetBSD-*aarch64eb, since it now fails both to cross-build and to build natively. Ref. rust-lang/rust#146842 * Adjusted patches, checksum updates etc. Upstream changes: Version 1.90 (2025-09-18) ========================== Language -------- - [Split up the `unknown_or_malformed_diagnostic_attributes` lint] (rust-lang/rust#140717). This lint has been split up into four finer-grained lints, with `unknown_or_malformed_diagnostic_attributes` now being the lint group that contains these lints: 1. `unknown_diagnostic_attributes`: unknown to the current compiler 2. `misplaced_diagnostic_attributes`: placed on the wrong item 3. `malformed_diagnostic_attributes`: malformed attribute syntax or options 4. `malformed_diagnostic_format_literals`: malformed format string literal - [Allow constants whose final value has references to mutable/external memory, but reject such constants as patterns] (rust-lang/rust#140942) - [Allow volatile access to non-Rust memory, including address 0] (rust-lang/rust#141260) Compiler -------- - [Use `lld` by default on `x86_64-unknown-linux-gnu`] (rust-lang/rust#140525). - [Tier 3 `musl` targets now link dynamically by default] (rust-lang/rust#144410). Affected targets: - `mips64-unknown-linux-muslabi64` - `powerpc64-unknown-linux-musl` - `powerpc-unknown-linux-musl` - `powerpc-unknown-linux-muslspe` - `riscv32gc-unknown-linux-musl` - `s390x-unknown-linux-musl` - `thumbv7neon-unknown-linux-musleabihf` Platform Support ---------------- - [Demote `x86_64-apple-darwin` to Tier 2 with host tools] (rust-lang/rust#145252) Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support.

Programs relying on signals to terminate them should update handling of sockets to handle errors on write by exiting. - [On Unix `std::env::home_dir` will use the fallback if the `HOME` environment variable is empty] (rust-lang/rust#141840) - We now [reject unsupported `extern "{abi}"`s consistently in all positions] (rust-lang/rust#142134). This primarily affects the use of implementing traits on an `extern "{abi}"` function pointer, like `extern "stdcall" fn()`, on a platform that doesn't support that, like aarch64-unknown-linux-gnu. Direct usage of these unsupported ABI strings by declaring or defining functions was already rejected, so this is only a change for consistency. - [const-eval: error when initializing a static writes to that static] (rust-lang/rust#143084) - [Check that the `proc_macro_derive` macro has correct arguments when applied to the crate root] (rust-lang/rust#143607) Version 1.89.0 (2025-08-07) ========================== Language -------- - [Stabilize explicitly inferred const arguments (`feature(generic_arg_infer)`)] (rust-lang/rust#141610) - [Add a warn-by-default `mismatched_lifetime_syntaxes` lint.] (rust-lang/rust#138677) This lint detects when the same lifetime is referred to by different syntax categories between function arguments and return values, which can be confusing to read, especially in unsafe code. This lint supersedes the warn-by-default `elided_named_lifetimes` lint. - [Expand `unpredictable_function_pointer_comparisons` to also lint on function pointer comparisons in external macros] (rust-lang/rust#134536) - [Make the `dangerous_implicit_autorefs` lint deny-by-default] (rust-lang/rust#141661) - [Stabilize the avx512 target features] (rust-lang/rust#138940) - [Stabilize `kl` and `widekl` target features for x86] (rust-lang/rust#140766) - [Stabilize `sha512`, `sm3` and `sm4` target features for x86] (rust-lang/rust#140767) - [Stabilize LoongArch target features `f`, `d`, `frecipe`, `lasx`, `lbt`, `lsx`, and `lvz`] (rust-lang/rust#135015) - [Remove `i128` and `u128` from `improper_ctypes_definitions`] (rust-lang/rust#137306) - [Stabilize `repr128` (`#[repr(u128)]`, `#[repr(i128)]`)] (rust-lang/rust#138285) - [Allow `#![doc(test(attr(..)))]` everywhere] (rust-lang/rust#140560) - [Extend temporary lifetime extension to also go through tuple struct and tuple variant constructors] (rust-lang/rust#140593) Compiler -------- - [Default to non-leaf frame pointers on aarch64-linux] (rust-lang/rust#140832) - [Enable non-leaf frame pointers for Arm64EC Windows] (rust-lang/rust#140862) - [Set Apple frame pointers by architecture] (rust-lang/rust#141797) Platform Support ---------------- - [Add new Tier-3 targets `loongarch32-unknown-none` and `loongarch32-unknown-none-softfloat`] (rust-lang/rust#142053) Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support.
