It depends.  If nwcc has no knowledge of floating point
registers, then the optimized npx bzero and copyin/copyout
operations aren't available.  Nothing like a slow kernel.

It is also noted on the nwcc webpage that it does not
support bitfields.  Are bitfields absent from the kernel.

Additionally, the OP wants a toolchain to replace gcc.
FreeBSD is more than a kernel.
