Holds information about the inheritance path to a virtual base or function table pointer.
A record may contain as many vfptrs or vbptrs as there are base subobjects.

BasePath clang::VPtrInfo::ContainingVBases |
The set of possibly indirect vbases that contain this vbtable.
When a derived class indirectly inherits from the same vbase twice, we only keep vtables and their paths from the first instance.
Definition at line 442 of file VTableBuilder.h.
CharUnits clang::VPtrInfo::FullOffsetInMDC |
Static offset from the top of the most derived class to this vfptr, including any virtual base offset.
Only used for vftables.

const CXXRecordDecl* clang::VPtrInfo::IntroducingObject |
This is the class that introduced the vptr by declaring new virtual methods or virtual bases.
Definition at line 423 of file VTableBuilder.h.
BasePath clang::VPtrInfo::MangledPath |
The bases from the inheritance path that got used to mangle the vbtable name.
This is not really a full path like a CXXBasePath. It holds the subset of records that need to be mangled into the vbtable symbol name in order to get a unique name.

const CXXRecordDecl* clang::VPtrInfo::NextBaseToMangle |
The next base to push onto the mangled path if this path is ambiguous in a derived class.
If it's null, then it's already been pushed onto the path.

const CXXRecordDecl* clang::VPtrInfo::ObjectWithVPtr |
This is the most derived class that has this vptr at offset zero.
When single inheritance is used, this is always the most derived class. If multiple inheritance is used, it may be any direct or indirect base.

BasePath clang::VPtrInfo::PathToIntroducingObject |
This holds the base classes path from the complete type to the first base with the given vfptr offset, in the base-to-derived order.
Only used for vftables.
