Subject: [PATCH 0/1] LoongArch: Hard Float Support Of Math Functions.
Date: Thu, 3 Nov 2022 20:14:32 +0800 [thread overview]
Message-ID: <20221103121433.2909287-1-tangxiaolin@loongson.cn> (raw)
Hi, reviewers.
This patch contains hardware floating-point support of math fuctions
for the LoongArch ISA. LoongArch ISA has many hardware floating-point
instructions that can be used in the corresponding math functions,
and the performance of those newly implemented functions is good.
instructions functions
fma.{s/d} __fma{f/ }
f{max/min}.{s/d}, fclass.{s/d} __f{max/min}i{mum/mum_mum}{f/ }
f{maxa/mina}.{s/d} __f{max,min}mag{f/ }
f{maxa/mina}.{s/d}, fclass.{s/d __f{max/min}imum{_mag/_mag_num}{f/ }
fcopysign.{s/d __copysign{f/ }
frint.{s/d} __{ /l/ll}rint{f/ }
fscaleb.{s/d}, fclass.{s/d} __scalbn{f/ }, __ieee754__scalb{f/ }
flogb.{s/d}, fclass.{s/d} __logb{f/ }, __ieee754_ilogb{f/ }
fclass.{s/d} __fpclassify{f/ }, __issignaling{f/ }
