Units in the .dwo sections (both type and CU) don't have a str_offsets_base, which implies that the .debug_str_offsets.dwo section has to consist of a monolithic table of string offsets (without the 8 or 16-byte header that's specified in section 7.26 of the DWARF 5 standard).  Section 7.26 seems to say the opposite, though. It seems I'll have to clarify this with the DWARF5 folks.


Worth clarifying on the dwarf-discuss list but I believe the idea is that the .dwo would have a single .debug_str_offsets.dwo contribution (complete with header), corresponding to the .debug_str.dwo contribution, and all units in the compilation would share it just like they would ordinarily share the single .debug_str section in a non-split compilation.
