基本解释

The compiler will after all very likely compile the above assignment into a single machine instruction.
编译器极有可能把上述赋值语句编译成一条机器指令。
As we described earlier, an uncontested lock operation involves some setup and an atomic machine instruction.
如前所述，无争用锁定操作涉及了一些设置和一个原子机器指令。
First, you shouldn't assume that the above assignment would be compiled as a single machine instruction unless you personally verify the machine code yourself.
首先，不应该假定上述赋值语句一定会被编译成一条机器指令，除非亲自验证了机器代码。
