224 Contains the byte offset of a pointer that needs to be link-edited.
227 The link editor adds the value that is already stored at this offset
234 After the link editor resolves the absolute address for this symbol,
241 the link editor assumes that it is updating a pointer
242 that is part of a machine code instruction using pc-relative addressing.
