Subject: [PATCH v4 68/71] tcg/tci: Implement add2, sub2
Date: Wed, 17 Feb 2021 12:20:33 -0800 [thread overview]
Message-ID: <20210217202036.1724901-69-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210217202036.1724901-1-richard.henderson@linaro.org>
We already had the 32-bit versions for a 32-bit host; expand this
to 64-bit hosts as well. The 64-bit opcodes are new.
