Subject: [PATCH 3/4] target/rx: Move DISAS_UPDATE check for write to PSW
Date: Sun, 17 Apr 2022 09:51:29 -0700	[thread overview]
Message-ID: <20220417165130.695085-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220417165130.695085-1-richard.henderson@linaro.org>

Have one check in move_to_cr instead of one in each
function that calls move_to_cr.
