This instruction is a nop on all server cores (certainly on all cores that AIX supports) so it is fine to emit a nop instead of it. In fact, that is exactly what XL emits. So we emit a nop on AIX and we leave the codegen as is on other platforms since there may indeed be cores out there for which this actually does some prefetching.
