Subject: [Qemu-devel] [PATCH v3 12/12] target/arm: Add missing clear_tail calls
Date: Fri, 8 Feb 2019 19:38:47 -0800 [thread overview]
Message-ID: <20190209033847.9014-13-richard.henderson@linaro.org> (raw)
In-Reply-To: <20190209033847.9014-1-richard.henderson@linaro.org>
Fortunately, the functions affected are so far only called from SVE,
so there is no tail to be cleared. But as we convert more of AdvSIMD
to gvec, this will matter.
