As I’ve written before, more than a year ago Rust on AVR went into the weeds because of bugs in LLVM.

I made a workaround, but it was far from ideal - and if it’s been frustrating for me, I’m sure it’s been a complete barrier to many even getting started with AVR on Rust.

Anyway, all that has now changed, thanks to Patryk27, who has managed to merge the necessary patches into the Rust master, so now the regular Rust nightly toolchain builds for AVR again. Hurrah, and the inaugural (and possibly ultimate) ‘Hero of the Week’ award goes to Patryk :-).
