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/ }

I will send a patch to remove the RISCV version as well. > 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/ } > The rest looks ok, although for the max/min/ilog/log/fpclassify/issignalling function I would expect that eventually compiler will start to provide builtins and optimize the calls without the need of libc. Specially because glibc itself uses a lot of such symbols internally, so we will need compiler support to avoid using internal hacks such math_private.h. Also please split the patch to have one for each symbol (it make sense to pack version for different floating types in one patch). Besides it, replace __builtin_expect with __glibc_likely and add a brief description on each file header. There are also minor style issues, such missing space after 'volatile' asm directive. > * sysdeps/loongarch/fpu/e_ilogb.c: New file. > * sysdeps/loongarch/fpu/e_ilogbf.c: Likewise. > *
