Subject: [PULL 10/76] target/microblaze: Split out BTR from env->sregs
Date: Mon, 31 Aug 2020 09:04:55 -0700 [thread overview]
Message-ID: <20200831160601.833692-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200831160601.833692-1-richard.henderson@linaro.org>
Continue eliminating the sregs array in favor of individual members.
Does not correct the width of BTR, yet.
