--- Comment #10 from Georg-Johann Lay <gjl at gcc dot gnu.org> ---
Unfortunately there are now cases where the subregs pop up during reload and
hence copy_to_mode_reg is prohibited like with strftime from avr-libc :-(
There are already insns that assume that subregs of constants work to some
degree like xload8<mode>_A and xload<mode>_A. Maybe we'll have to support
subregs of constants in their own right...
