Subject: [Qemu-devel] [PATCH v2 21/22] s390x/tcg: Allow linux-user to use vector instructions
Date: Mon,  3 Jun 2019 11:06:34 +0200	[thread overview]
Message-ID: <20190603090635.10631-22-david@redhat.com> (raw)
In-Reply-To: <20190603090635.10631-1-david@redhat.com>

Once we unlock S390_FEAT_VECTOR for TCG, we want linux-user to be
able to make use of it.
