Since yesterday, the LLVM `main` branch should have working `f16` on all platforms that Rust supports; this will be LLVM version 22, so update how `cfg(target_has_reliable_f16)` is set to reflect this. Within the rust-lang organization, this currently has no effect. The goal is to start catching problems as early as possible in external CI that runs top-of-tree rust against top-of-tree LLVM, and once testing for the rust-lang bump to LLVM 22 starts. Hopefully this will mean that we can fix any problems that show up before the bump actually happens, meaning `f16` will be about ready for stabilization at that point (with some considerations for the GCC patch at [1] propagating).

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
