17 **AST**
18 Abstract Syntax Tree.
20 Due to Clang's influence (mostly the fact that parsing and semantic
21 analysis are so intertwined for C and especially C++), the typical
22 working definition of AST in the LLVM community is roughly "the
23 compiler's first complete symbolic (as opposed to textual)
24 representation of an input program".
25 As such, an "AST" might be a more general graph instead of a "tree"
26 (consider the symbolic representation for the type of a typical "linked
27 list node"). This working definition is closer to what some authors
28 call an "annotated abstract syntax tree".
