Subject: [PATCH 68/76] target/sparc: Drop free_compare
Date: Fri, 24 Feb 2023 23:14:19 -1000	[thread overview]
Message-ID: <20230225091427.1817156-69-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230225091427.1817156-1-richard.henderson@linaro.org>

Translators are no longer required to free tcg temporaries.
Remove the g1 and g2 members of DisasCompare, as they were
used to track which temps needed to be freed.
