Subject: [RFC v3 12/23] target/arm: move cpsr_read, cpsr_write to cpu_common
Date: Wed,  3 Mar 2021 12:40:42 +0100
Message-ID: <20210303114053.20305-13-cfontana@suse.de> (raw)
In-Reply-To: <20210303114053.20305-1-cfontana@suse.de>

we need as a result to move switch_mode too,
so we put an implementation into cpu_user and cpu_sysemu.
