Clang 3.8 is pretty old, but it should support all of these
instructions. But those instructions are for AArch32 and if you're
compiling for Cortex-A72 you'd naturally be using the new 64-bit
AArch64 instruction set.

So what I suspect is happening is that the project is choosing the old
ARMv7 assembly implementations, either because it doesn't have 64-bit
ones or because something strange in the configuration is taking it
down that path.

Either way, you probably need to contact people involved with NE10 to
sort out what's going on.

Cheers.

Tim.
