Set branch protection function attributes by nikic · Pull Request #128141 · rust-lang/rust
Since LLVM 19, it is necessary to set not only module flags, but also function attributes for branch protection on aarch64. See llvm/llvm-project@e15d67c for the relevant LLVM change.

Update to LLVM 19 The LLVM 19.1.0 final release is planned for Sep 3rd. The rustc 1.82 stable release will be on Oct 17th. The unstable MC/DC coverage support is temporarily broken by this update. It will be restored by rust-lang#126733. The implementation changed substantially in LLVM 19, and there are no plans to support both the LLVM 18 and LLVM 19 implementation at the same time. Compatibility note for wasm: > WebAssembly target support for the `multivalue` target feature has changed when upgrading to LLVM 19. Support for generating functions with multiple returns no longer works and `-Ctarget-feature=+multivalue` has a different meaning than it did in LLVM 18 and prior. The WebAssembly target features `multivalue` and `reference-types` are now both enabled by default, but generated code is not affected by default. These features being enabled are encoded in the `target_features` custom section and may affect downstream tooling such as `wasm-opt` consuming the module, but the actual generated WebAssembly will continue to not use either `multivalue` or `reference-types` by default. There is no longer any supported means to generate a module that has a function with multiple returns. Related changes: * rust-lang#127605 * rust-lang#127613 * rust-lang#127654 * rust-lang#128141 * llvm/llvm-project#98933 Fixes rust-lang#121444. Fixes rust-lang#128212.
