Actually I would like to make clang+llvm+lld fully compatible with gcc+binutils (functionality, ABI, quality, ...), and finally replace avr-gcc as Arduino's default toolchain. (https://www.arduino.cc/en/software, Arduino is a popular MCU platform for hardware prototype development & verification) Even many avr-libc (https://www.nongnu.org/avr-libc/) developers are trying build it with clang. If you think it is complex, we can remove the extreme check of `-x assembler-with-cpp`, which is rarely in a real world.
