Subject: [PATCH 1/7] target/arm: Fix missing temp frees in do_vshll_2sh
Date: Tue, 9 Jun 2020 17:02:03 +0100 [thread overview]
Message-ID: <20200609160209.29960-2-peter.maydell@linaro.org> (raw)
In-Reply-To: <20200609160209.29960-1-peter.maydell@linaro.org>
The widenfn() in do_vshll_2sh() does not free the input 32-bit
TCGv, so we need to do this in the calling code.
