Subject: [PATCH v9 08/24] target/arm: Split out rebuild_hflags_aprofile
Date: Wed, 23 Oct 2019 11:00:41 -0400 [thread overview]
Message-ID: <20191023150057.25731-9-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191023150057.25731-1-richard.henderson@linaro.org>
Create a function to compute the values of the TBFLAG_ANY bits
that will be cached, and are used by A-profile.
