现有JMM 表明易失性的读和写是直接和主存打交道的，这样避免了把值存储到寄存器或者绕过处理器特定的缓存。
The existing JMM says that volatile reads and writes are to go directly to main memory, prohibiting caching values in registers and bypassing processor-specific caches.
类似地，函数也可以假设它给非易失性寄存器赋的值在调用其他函数时都不会被修改(至少会重新恢复)。
Likewise, a function may also assume that the values it assigns to non-volatile registers will not be modified (or at least will be restored) when it makes calls to other functions.
非易失性存储设备一般为硬盘，但也可以是安全数字（SD）卡之类的固态设备，甚至可以是磁带设备（不过现在已经过时了）。

在现代计算机中，这些指令被存储在一块被称为“非易失性”存储器上，而这块存储器属于处理器本身的一部分。
In a modern computer, these instructions are held in a so-called non-volatile memory that is part of the processor itself.
寄存器3 到 12是易失性寄存器，这意味着任何函数都可以自由地对这些寄存器进行修改，而不用恢复这些寄存器之前的值。
Registers 3-12 are volatile registers, which means that any function can modify them freely without having to restore their previous value.
