--- Comment #8 from Drea Pinski <pinskia at gcc dot gnu.org> --- (In reply to Konstantinos Eleftheriou from comment #7) > Thanks Andrew!

Right I think AVR's definition of MAX_FIXED_MODE_SIZE is broken. It should be 64bit otherwise DImode is invalid to be used too. I have to dig into that more. There are other places which use MAX_FIXED_MODE_SIZE in this way too. We had to fix recently MIPS's defition of MAX_FIXED_MODE_SIZE for the same reason.
