--- Comment #5 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > Hi, can you clarify what you mean? Why does -gsplit-dwarf without -gdwarf-5 > emit in debug fission with extended dwarf-4 if it's specifically dealing > with dwarf 5? The sentence is indeed a bit ambiguous: -gsplit-dwarf has a specific treatment for DWARF 5 and later and another treatment for earlier DWARF versions.
