Subject: [PATCH v4 10/27] target/s390x: Use gen_psw_addr_disp in pc_to_link_info
Date: Mon, 20 Feb 2023 08:40:35 -1000	[thread overview]
Message-ID: <20230220184052.163465-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230220184052.163465-1-richard.henderson@linaro.org>

This is slightly more complicated than a straight displacement
for 31 and 24-bit modes.  Dont bother with a cant-happen assert.
