Looks like ARM also does better code with the generic implementation as
it seems to have some looking like conditional instructions 'rorne' and
'strne'.
In arm32 (and I think arm64) every instruction is conditional.
Almost every instruction in arm32. There are a number of unconditional
instructions that were introduced.
