Hi,

People are still ironing out kinks/differences with clang. Anyone
saying otherwise is likely pushing an agenda. :-)

Thus I think adding clang-only code to the system right now is very,
very premature. There still seem to be reasons to run systems on GCC
instead of clang.

If you have a need for new instruction support, perhaps look at adding
it to our base GCC for the time being?

Remember, you're not the only consumer of the system. :-)
