Subject: [PATCH v4 17/30] tcg/loongarch64: Implement add/sub ops
Date: Fri, 24 Sep 2021 00:59:26 +0800	[thread overview]
Message-ID: <20210923165939.729081-18-git@xen0n.name> (raw)
In-Reply-To: <20210923165939.729081-1-git@xen0n.name>

The neg_i{32,64} ops is fully expressible with sub, so omitted for
simplicity.
