const IdentifierInfo* clang::HeaderFileInfo::ControllingMacro |
If this file has a #ifndef XXX (or equivalent) guard that protects the entire contents of the file, this is the identifier for the macro that controls whether or not it has any effect.
Note: Most clients should use getControllingMacro() to access the controlling macro of this header, since getControllingMacro() is able to load a controlling macro from external storage.

unsigned clang::HeaderFileInfo::ControllingMacroID |
The ID number of the controlling macro.
This ID number will be non-zero when there is a controlling macro whose IdentifierInfo may not yet have been loaded from external storage.

unsigned clang::HeaderFileInfo::DirInfo |
DirInfo - Keep track of whether this is a system header, and if so, whether it is C++ clean or not.
This can be set by the include paths or by #pragma gcc system_header. This is an instance of SrcMgr::CharacteristicKind.

unsigned clang::HeaderFileInfo::IndexHeaderMapHeader |
Whether this is a header inside a framework that is currently being built.
When a framework is being built, the headers have not yet been placed into the appropriate framework subdirectories, and therefore are provided via a header map. This bit indicates when this is one of those framework headers.
