Subject: [PATCH 66/76] target/sparc: Drop get_temp_i32
Date: Fri, 24 Feb 2023 23:14:17 -1000 [thread overview]
Message-ID: <20230225091427.1817156-67-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230225091427.1817156-1-richard.henderson@linaro.org>
Translators are no longer required to free tcg temporaries,
therefore there's no need to record temps for later freeing.
Replace the few uses with tcg_temp_new_i32.
