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. -- Steve
