Subject: [PATCH v4 19/24] test/xmmt_ops: add dummy vector implementation for LoongArch
Date: Thu, 21 Jul 2022 20:51:39 +0800	[thread overview]
Message-ID: <20220721125144.4028113-20-zhoumin@loongson.cn> (raw)
In-Reply-To: <20220721125144.4028113-1-zhoumin@loongson.cn>

The hardware instructions based vector implementation will come
in a future patch. This dummy implementation can also work.
