/// describe variables or functions that resolves to the corresponding
/// code section(and thus have entries in the Addresses map). All the debug
/// information that will be generated(the DIEs, but also the line
/// tables, ranges, ...) is derived from that set of root DIEs.
///
/// The root DIEs are identified because they contain relocations that
/// points to code section(the low_pc for a function, the location for
/// a variable). These relocations are called ValidRelocs in the
/// AddressesInfo and are gathered as a very first step when we start
/// processing a object file.
