However, constant folding will be unable to determine this fact.
然而，常数合并无法确定这个事实。
This is valuable information because you can construct expressions that can be optimized through constant folding.
这种信息非常有价值，因为可以构造出能够通过常量叠算(constant folding)优化的表达式。
The example used above can be optimized by constant folding because the computation generating the constant is in the same control-flow block.
上面使用的那个例子能通过常数合并最优化，是因为生成常数的计算处在相同的控制流块中。
If a virus writer, or a metamorphic engine, attempts to obfuscate the computation of the port number, the anti-virus system may apply constant folding to de-obfuscate it.
如果某个病毒作者或变形引擎企图使端口号的计算变得混乱，反病毒系统可能运用常数合并来反混淆。
