Which ARM core?哪个ARM核心？

According to for ARMv7: https://developer.arm.com/documentation/ddi0406/cb/Application-Level-Architecture/Instruction-Details/Alphabetical-list-of-instructions/CPY They are synonyms, meaning they translate to the same instruction.根据 ARMv7： https://developer.arm.com/documentation/ddi0406/cb/Application-Level-Architecture/Instruction-Details/Alphabetical-list-of-instructions/CPY它们是同义词，意思是它们翻译成相同的操作说明。
