◆ isCompatibleFile()

◆ loadObject()

◆ processRelocationRef()

Parses one or more object file relocations (some object files use relocation pairs) and stores it to Relocations or SymbolRelocations (this depends on the object file type).

Returns

Iterator to the next relocation that needs to be parsed.
