Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #30 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The GCC behavior is completely intentional and correct. As I've tried to explain, there can't be an ABI change any time a wider hardware vector type is added for the former ISAs. There is a warning when passing the generic vectors wider than hw sizes which have hw size in newer ISAs as function arguments or returning them.
