另外，如果希望使用某条特定指令而不希望编译器来选择指令，那么可以使用specific intrinsic来执行几乎所有的非分支指令。
In addition, if you want a specific instruction rather than having the compiler choose one, you can perform almost any non-branching instruction with the specific intrinsics.
这个程序最终要做的是计算两种答案，然后使用一个条件指令来选择所需要的答案。
What the program will end up doing is calculating both answers, and then using a conditional instruction to select the desired answer.
