Chih-Min Chao 0e9030376e softfloat: add APIs to handle alternative sNaN propagation for fmax/fmin For "fmax/fmin ft0, ft1, ft2" and if one of the inputs is sNaN, The original logic: Return NaN and set invalid flag if ft1 == sNaN \|\| ft2 == sNan. The alternative path: Set invalid flag if ft1 == sNaN \|\| ft2 == sNaN. Return NaN only if ft1 == NaN && ft2 == NaN. The IEEE 754 spec allows both implementation and some architecture such as riscv choose different defintions in two spec versions. (riscv-spec-v2.2 use original version, riscv-spec-20191213 changes to alternative) Signed-off-by: Chih-Min Chao <chihmin.chao@sifive.com> Signed-off-by: Frank Chang <frank.chang@sifive.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20211021160847.2748577-2-frank.chang@sifive.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>		5 years ago
