likely

linux中 likely与unlikely

看内核时总遇到if(likely()){}或是if(unlikely())这样的语句，最初不解其意，现在有所了解，所以也想介绍一下。

内核中的 likely() 与 unlikely()

内核中的likely()与unlikely()在2.6内核中，随处可以见到likely()和unlikely()的身影，那么为什么要用它们？它们之间有什么区别？

分支声明likely()/unlikely()

分支声明likely()/unlikely()   对于条件语句，gcc内建了一条指令用于优化，在一个条件经常出现，或者该条件很少出现的时候，编译器可以根据这条指令对条件分支进行优化。

GCC——分支预测(likely和unlikey)

    最近在拜读一个项目源代码的过程中，发现了一个有意思的GCC特性，现将这个特性总结如下：    开发人员在开发服务的过程中，可以根据业务逻辑的特性来判断当前的条件语句被执行的概率情况，经常被执行到的代码片段可以紧邻顺序执行的代码片段后边，偶尔被执行到的条件代码片段被放到其他代码片段，从而减少代码在顺序执行过程中的代码上下文的跳转次数，达到提高程序执行效率的目的。这种方式的优化，需要严重的依赖
