Subject: [PATCH] target/arm: fix TCG leak for fcvt half->double
Date: Fri, 31 Jan 2020 15:34:39 +0000	[thread overview]
Message-ID: <20200131153439.26027-1-alex.bennee@linaro.org> (raw)

When support for the AHP flag was added we inexplicably only freed the
new temps in one of the two legs. Move those tcg_temp_free to the same
level as the allocation to fix that leak.
