◆ addAccess()

ChangeStatus llvm::AA::PointerInfo::State::addAccess ( Attributor A,
int64_t  Offset,
int64_t  Size,
Instruction I,
Optional< Value * >  Content,
AAPointerInfo::AccessKind  Kind,
Type Ty,
Instruction RemoteI = nullptr 

Add a new Access to the state at offset Offset and with size Size.

The access is associated with I, writes Content (if anything), and is of kind Kind. If an Access already exists for the same I and same RemoteI, the two are combined, potentially losing information about offset and size. The resulting access must now be moved from its original OffsetBin to the bin for its new offset.

\Returns CHANGED, if the state changed, UNCHANGED otherwise.
