--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The reason that the non-lowpart subreg is allowed here is:
sparc_regmode_natural_size (machine_mode mode)
which returns for MODE_VECTOR_INT modes 4 rather than UNITS_PER_WORD (and for
MODE_FLOAT too).
IRA decision for the pseudo 114 seems to be mem.
