--- Comment #11 from Uroš Bizjak <ubizjak at gmail dot com> ---
The fix is too risky for release branches (4.9-), where RA won't perform a r->m
fixup on disabled alternative if Yi is used.
The gcc will generate a dead store for TARGET_INTER_UNIT_MOVES_TO_VEC targets
with vec_set<mode>_0, which is a minor issue. -mtune=generic generates correct
code, since TARGET_INTER_UNIT_MOVES_TO_VEC is disabled in this case.
