const Decl * D
Defines the clang::SourceLocation class and associated facilities.
Decl - This represents one declaration (or definition), e.g.
Definition: DeclBase.h:86
An opaque identifier used by SourceManager which refers to a source file (MemoryBuffer) along with it...
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
This class handles loading and caching of source files into memory.
Stores the declaration occurrences seen in a particular source or header file of a translation unit.
void print(llvm::raw_ostream &OS, SourceManager &SM) const
ArrayRef< DeclOccurrence > getDeclOccurrencesSortedByOffset() const
void addMacroOccurence(SymbolRoleSet Roles, unsigned Offset, const IdentifierInfo *Name, const MacroInfo *MI)
Adds an occurrence of the given macro at the supplied Offset.
void addDeclOccurence(SymbolRoleSet Roles, unsigned Offset, const Decl *D, ArrayRef< SymbolRelation > Relations)
Adds an occurrence of the canonical declaration D at the supplied Offset.
void removeHeaderGuardMacros()
Remove any macro occurrences for header guards.
