WebIn general, the AST is a better structure for later stages of the compiler because it omits details having to do with the source language, and just contains information about the essential structure of the program.

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.
