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.

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.
Definition at line 439 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.

BaseWithVPtr is at this offset from its containing complete object or virtual base.

BasePath clang::VPtrInfo::PathToBaseWithVPtr |
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.
Definition at line 435 of file VTableBuilder.h.
const CXXRecordDecl* clang::VPtrInfo::ReusingBase |
The vtable will hold all of the virtual bases or virtual methods of ReusingBase.
This may or may not be the same class as VPtrSubobject.Base. A derived class will reuse the vptr of the first non-virtual base subobject that has one.
