WebLibTooling is a Clang C++ library that supports the con-struction of tools that leverage the Clang parsing front-end [7]. LibTooling can be used to extract both syntactic and semantic information about a program by permitting access to the Clang abstract syntax tree (AST), which contains both syntactic and semantic information about the program WebJan 28, 2024 · On the other hand, the AST generated by Clang has the following characteristics: The first statement is always a TranslationUnitDecl: Figure 5: TranslationUnitDecl in the Clang AST. ...

WebWe use the codegen () method to emit an IR for the AST node along with its dependencies. All codegen () methods return an LLVM value object. Value is a class representing a SSA (Static Single Assignment) register or SSA value in LLVM. SSA values are computed while the related instructions execute and don't get a new value until the instruction ...
