Detailed Description

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.

Member Data Documentation

const CXXRecordDecl* clang::VPtrInfo::BaseWithVPtr

The vptr is stored inside this subobject.

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 430 of file VTableBuilder.h.

Referenced by getVBaseWithVPtr().

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.

Definition at line 421 of file VTableBuilder.h.

Referenced by extendPath(), mangleVFTableName(), and rebucketPaths().

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.

Definition at line 425 of file VTableBuilder.h.

Referenced by extendPath().

CharUnits clang::VPtrInfo::NonVirtualOffset

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

Definition at line 412 of file VTableBuilder.h.

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.
