AVR should be working these days https://github.com/llvm/llvm-project/tree/main/llvm/lib/Target/AVR https://github.com/llvm/llvm-project/tree/main/llvm/lib/Targ... Unless you mean some specific chips?

  Also while ESP32 has not been mainlined (I think), Espressif has both an llvm and a rustc fork.

    Espressif has forks of everything (OpenOCD, GDB, GCC) that they never mainline and that just become outdated as they release new chips. The latest xtensa-esp8266-elf-gcc is version 5.2
