And the x86 code uses inline assembler. That's not viable on any ISA with sane 
conventions such as Arm or RISC-V. The compiler will reject our vector 
clobbers, unless the Vector extension is included in the compilation target. 
But then that breaks run-time detection, and will be rejected by all Linux 
distros.
