--- Comment #8 from Jason Merrill <jason at gcc dot gnu.org> --- (In reply to Richard Biener from comment #5) > There are also quite many _name_ duplicates refering to different DIEs! Like > 178 copies of 'std::is_same_v' and others: std::*_v are variable templates, so the different DIEs are for different instantiations of the template. I don't remember what the right pubnames behavior is for variable templates.
