Subject: [PULL 23/46] tcg/tci: Remove dead code for TCG_TARGET_HAS_div2_*
Date: Fri,  5 Feb 2021 12:56:27 -1000	[thread overview]
Message-ID: <20210205225650.1330794-24-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210205225650.1330794-1-richard.henderson@linaro.org>

We do not simultaneously support div and div2 -- it's one
or the other.  TCI is already using div, so remove div2.
