Subject: [PATCH 56/72] softfloat: Introduce Floatx80RoundPrec
Date: Fri, 7 May 2021 18:47:46 -0700 [thread overview]
Message-ID: <20210508014802.892561-57-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210508014802.892561-1-richard.henderson@linaro.org>
Use an enumeration instead of raw 32/64/80 values.
