Subject: [PATCH 36/72] softfloat: Move mul_floats to softfloat-parts.c.inc
Date: Fri,  7 May 2021 18:47:26 -0700
Message-ID: <20210508014802.892561-37-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210508014802.892561-1-richard.henderson@linaro.org>

Rename to parts$N_mul.
Reimplement float128_mul with FloatParts128.
