--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The two builtins share DECL_ASSEMBLER_NAME, __ssabs_2. Can it be the AVR
backend misuses DECL_ASSEMBLER_NAME for builtins somehow? They have different
return mode, HQ vs. HA mode.
It might be possible to avoid diagnosing this but the middle-end can't see
that there is no ABI issue.
