const Decl * D
Forward-declares and imports various common LLVM datatypes that clang wants to use unqualified.
Defines the clang::MacroInfo and clang::MacroDirective classes.
Decl - This represents one declaration (or definition), e.g.
Definition: DeclBase.h:86
One of these records is kept for each identifier that is lexed.
Encapsulates the data about a macro definition (e.g.
Definition: MacroInfo.h:39
The JSON file list parser is used to communicate input to InstallAPI.
