pcc added a comment. > Any callee-saved register can be used.
In fact, any register may be used, as long as it cannot be used to pass arguments or return values. It may be better to select a temporary register, as `x18` is on aarch64 when not being used as a platform register, so that problems are noticed more easily (i.e. more likely to be clobbered by incompatible code).
