Zig shipped a RISC-V backend before AArch64! I think RISC-V is doing really well in the technology enthusiast community.

A really fun (10 minute) talk on developing an LLVM backend for 6502, a chip with only three registers and a teeny tiny stack: https://www.youtube.com/watch?v=2lW3WHPtmKo

Zig has moved to a compiler bootstrap approach that uses webassembly: https://ziglang.org/news/goodbye-cpp/ They check in the wasm artifact and provide their own wasm compiler. wasm is the most portable backend supported by LLVM. OCaml does something similar! It includes a minimal VM.
