◆ BitWidth

uint32_t llvm::DataLayout::PointerSpec::BitWidth

◆ HasExternalState

bool llvm::DataLayout::PointerSpec::HasExternalState

Pointers in this address space have additional state bits that are located at a target-defined location when stored in memory.

An example of this would be CHERI capabilities where the validity bit is stored separately from the pointer address+bounds information.

◆ HasUnstableRepresentation

bool llvm::DataLayout::PointerSpec::HasUnstableRepresentation

Pointers in this address space don't have a well-defined bitwise representation (e.g.

they may be relocated by a copying garbage collector and thus have different addresses at different times).

◆ IndexBitWidth

uint32_t llvm::DataLayout::PointerSpec::IndexBitWidth

The index bit width also defines the address size in this address space.

If the index width is less than the representation bit width, the pointer is non-integral and bits beyond the index width could be used for additional metadata (e.g. AMDGPU buffer fat pointers with bounds and other flags or CHERI capabilities that contain bounds+permissions).
