Rust on Morello
summary
A Rust toolchain is ported to Morello prototype hardware, swapping the LLVM backend and making the compiler and core/std build and run; pointer storage is 128 bits with 64-bit addressing so usize=64 choice is used to avoid breaking code. A crater run over 38,722 projects reports under 1% failing a provenance lint. Benchmarks cover 8,702 crates (≈108,000 LOC with ≈100,000 unsafe lines) and show a measured 39% average slowdown for full Morello checks versus unchecked runs. Binaries and scripts are published for testing.
