Subject: [PATCH v2 03/27] target/s390x: Use tcg_constant_i32 for fpinst_extract_m34
Date: Sun, 11 Dec 2022 09:27:38 -0600 [thread overview]
Message-ID: <20221211152802.923900-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20221211152802.923900-1-richard.henderson@linaro.org>
Return a constant or NULL, which means the free may be
removed from all callers of fpinst_extract_m34.
