Subject: [PATCH 59/72] softfloat: Convert floatx80_add/sub to FloatParts
Date: Fri,  7 May 2021 18:47:49 -0700	[thread overview]
Message-ID: <20210508014802.892561-60-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210508014802.892561-1-richard.henderson@linaro.org>

Since this is the first such, this includes all of the
packing and unpacking routines as well.
