Web基于IR生成控制流图CFG. 控制流分析（Control Flow Analysis）通常指的是构建控制流图（Control Flow Graph, CFG），并以 CFG 作为基础结构进行静态分析的过程。 CFG 的一个结点可以是一条单独的 3AC，但是更常见的是一个基本块（Basic Block）。所谓基本块，就是满足以下性质 ... WebClang’s AST is different from ASTs produced by some other compilers in that it closely resembles both the written C++ code and the C++ standard. For example, parenthesis expressions and compile time constants are available in an unreduced form in the AST. This makes Clang’s AST a good fit for refactoring tools. ruta infarchcdd01 sys trabajo invper2011
