Decl - This represents one declaration (or definition), e.g.
Definition: DeclBase.h:85
bool isCanonicalDecl() const
Whether this particular Decl is a canonical one.
Definition: DeclBase.h:975
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
Represents an unpacked "presumed" location which can be presented to the user.
unsigned getColumn() const
Return the presumed column number of this location.
const char * getFilename() const
Return the presumed filename of this location.
unsigned getLine() const
Return the presumed line number of this location.
Encodes a location in the source.
This class handles loading and caching of source files into memory.
void print(llvm::raw_ostream &OS, SourceManager &SM) 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.
