M. Tim Jones 是一名嵌入式软件工程师.这里是他在IBM上发表的一编关于linux下GCC编译器的一些优化知识。比如：内核中常见到的likely() unlikely() __must_check 等等函数和函数属性从何而来，有什么作用，及如何对变量优化，对结构或函数添加属性等等。-M. Tim Jones, Consultant Engineer, Emulex Corp. M. Tim Jones is an embedded software engineer. Here is his IBM published a series on the GCC compiler under linux some optimization knowledge. For example: the common core to the likely () unlikely () __must_check function and the function attributes and so on came from, what role, and how to optimize on the variable, add the attribute on the structure or function, and so on.
