Xtensa LLVM-upstream is experimental, added in 
https://github.com/ldc-developers/llvm-project/releases/tag/ldc-v19.1.3 for new ldc2 releases - with upstream LLVM-Xtensa (opaque/generic cpu-features)

more info: https://github.com/ldc-developers/ldc/issues/4725

For Xtensa lx6/lx7 need use espressif/llvm-project (fork) 
backend, like https://github.com/Reavershark/esp-dlang
