Some candy ass architectures won't allow EXECUTE instructions to address another EXECUTE instruction the target instruction.
有些编译器不允许EXECUTE指令象对目标指令那样对另一个EXECUTE指令寻址。
Some candyass architectures won't allow EXECUTE instructions to address another EXECUTE instruction as the target instruction. Real Programmers despise petty restrictions.
某些体系结构不允许执行指令指向目标指令的地址,真正的程序员才不管这种小小的限制。
We execute that instruction and we move to the next one.
我们执行那个指令,并继续下一轮。
Well at most, I'm going to execute each instruction once. All right?
那么至多的话,我会执行,每个指令一次,对不对?
We execute that instruction, we move to the next one.
我们执行那个指令,我们继续下一轮。
Remember last time, I said that there's different kinds of complexity in our code, and I suggested for simple branching programs, the amount of time it takes to run that program is, in essence, bounded by the number of instructions, because you only execute each instruction at most once.
但是这里有个很重要的点,记得上节课,我提过在我们的代码中,有不同种类的复杂度,而且我还说了对于简单的分支程序,运行这种程序需要的总体时间,大体上,是和指令的数目相关的,因为每个指令只会被执行最多一次。
