target/i386: Remove compilation errors when -Werror=maybe-uninitialized
To avoid compilation errors when -Werror=maybe-uninitialized is used, add a default case with g_assert_not_reached(). Otherwise with GCC 11.3.1 "cc (GCC) 11.3.1 20220421 (Red Hat 11.3.1-2)" we get: ../target/i386/ops_sse.h: In function ‘helper_vpermdq_ymm’: ../target/i386/ops_sse.h:2495:13: error: ‘r3’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 2495 | d->Q(3) = r3; | ~~~~~~~~^~~~ ../target/i386/ops_sse.h:2494:13: error: ‘r2’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 2494 | d->Q(2) = r2; | ~~~~~~~~^~~~ ../target/i386/ops_sse.h:2493:13: error: ‘r1’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 2493 | d->Q(1) = r1; | ~~~~~~~~^~~~ ../target/i386/ops_sse.h:2492:13: error: ‘r0’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 2492 | d->Q(0) = r0; | ~~~~~~~~^~~~ Signed-off-by: Eric Auger <eric.auger@redhat.com> Message-Id: <20221222140158.1260748-1-eric.auger@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
