Subject: [PATCH 1/7] target/microblaze: Rename DISAS_UPDATE to DISAS_EXIT
Date: Wed, 2 Sep 2020 09:35:53 -0700 [thread overview]
Message-ID: <20200902163559.1077728-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200902163559.1077728-1-richard.henderson@linaro.org>
The name "update" suggests that something needs updating, but
this is not the case. Use "exit" to emphasize that nothing
needs doing except to exit.
