> Explain the crate scanner thing?
I assume a reference to tools that help manage potential issues around dependencies, e.g.:
* https://github.com/rustsec/rustsec/tree/main/cargo-audit
* https://github.com/EmbarkStudios/cargo-deny
"[cargo-audit] Audit Cargo.lock files for crates with security vulnerabilities reported to the RustSec Advisory Database."
"cargo-deny is a cargo plugin that lets you lint your project's dependency graph to ensure all your dependencies conform to your expectations and requirements." e.g. license, security advisories, source.

The AVR codegen bug is discussed here: https://github.com/rust-lang/rust/issues/82242#issuecomment-... Seems to be due to the LLVM-AVR patchset somehow expecting gcc-compatible compiler intrinsics (for division), whereas Rust provides intrinsics derived from LLVM's compiler-rt, with different calling conventions.
