Subject: [PATCH v5 8/9] target/arm: Simplify sve mte checking
Date: Fri, 16 Apr 2021 11:31:05 -0700 [thread overview]
Message-ID: <20210416183106.1516563-9-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210416183106.1516563-1-richard.henderson@linaro.org>
Now that mte_check1 and mte_checkN have been merged, we can
merge sve_cont_ldst_mte_check1 and sve_cont_ldst_mte_checkN.
Which means that we can eliminate the function pointer into
sve_ldN_r and sve_stN_r, calling sve_cont_ldst_mte_check directly.
