--- Comment #2 from ktkachov at gcc dot gnu.org ---
Setting info->representable_p to false and returning on the condition that
GET_MODE_SIZE (ymode) + offset > GET_MODE_SIZE (xmode)
in that function fixes the ICE for me (though I haven't tested further) as
record_subregs_of_mode consciously tries to call subreg_get_info on a V2DI
subreg of an EImode (24 byte size) reg at offset 16, which is not valid
