Public bug reported: The rust-bytemuck autopkgtest fails on amd64 with rustc 1.88 (current rust-defaults)
The test `rust-bytemuck:@` runs with `--all-features`, which includes the `avx512_simd` feature. This feature uses AVX-512 BF16 SIMD types (`__m128bh`, `__m256bh`, `__m512bh`) which were stabilised in Rust 1.89: https://releases.rs/docs/1.89.0/ With `rustc 1.88`, these types require the nightly feature gate `stdarch_x86_avx512`, causing compilation errors: ``` error[E0658]: use of unstable library feature `stdarch_x86_avx512` ``` I suggest that the current resolution is to wait for rust-defaults to be updated to rustc 1.89+, then perform a no-change rebuild. ** Affects: rust-bytemuck (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2138643 Title: autopkgtest fails on amd64 - requires rustc 1.89 for AVX-512 BF16 types To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rust-bytemuck/+bug/2138643/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
