控制流图(Control Flow Graph, CFG)也叫控制流程图,是一个过程或程序的抽象表现,是用在编译器中的一个抽象数据结构,由编译器在内部维护,代表了一个程序执行过程中会遍历到的所有路径。它用图的形式表示一个过程内所有基本块执行的可能流向, 也能反映一个过程的实时执行过程。 Frances E. Allen于1970年提出控制...

编译使用CFG作为中间端的原因:编译器将源代码文件翻译成抽象语法树的数据结构,然后通过数据pipe将抽象语法树转换为更接近机器代码的control flow Graph。 抽象语法是人类视角 control flow graph可以属于机器视角 1.2 Basic Block(基本块) 在中间表示中,一般使用 Control Flow Graphs,而CFG中使用Basic Blocks来进行程序的...
