...ection which has one or more "contributions" in it. Each contribution has a header, which gives its size and whether the array elements are 32 or 64 bits wide. Any DWARF compile-unit or type-unit that uses the array (that is, any unit that uses any of the "strx" forms) has a DW_AT_str_offsets_base attribute that points to the 0th element of the array. The producer chooses whether to have one contribution shared by all units, one contribution per unit, or somewhere in between. There's an implication for how to read the .debug_str_offsets section, which is that the reader has to parse th...
