[PATCH v3 0/4] Enable generic math code for more arches

[PATCH v3 0/4] Enable generic math code for more arches

[Vineet Gupta]

Hi,

This was suggested by Adhemerval Zanella as part of ARC hard float
review.

changes since v2:
  - Add new defines (0) to s390 too as suggested by Stephan
  - Handle USE_FMA_BUILTIN in both sysdeps/ieee754/{dbl-64,ldbl-128}/s_fma.c
  - Add diff output for all arches build tested

build-glibc-many tested for following
  aarch64-linux-gnu
  arm-linux-gnueabi
  arm-linux-gnueabihf
  hppa-linux-gnu
  x86_64-linux-gnu
  riscv64-linux-gnu-rv64imac-lp64
  riscv64-linux-gnu-rv64imafdc-lp64
  powerpc-linux-gnu
  microblaze-linux-gnu
  nios2-linux-gnu
  hppa-linux-gnu
  s390x-linux-gnu"

Thx,
-Vineet

[PATCH v3 3/4] aarch/fpu: use generic builtins based math functions

[Vineet Gupta]

introduce sysdep header math-use-builtins.h to replace aarch64
implementations with corresponding generic ones.

 - newly inroduced generic sqrt{,f}, fma{,f}
 - existing floor{,f}, nearbyint{,f}, rint{,f}, round{,f}, trunc{,f}
 - Note that generic copysign was already enabled (via generic
   math-use-builtins.h) now thru sysdep header

Tested with build-many-glibcs for aarch64-linux-gnu

This is a non functional change and aarch64 libm before/after was
byte invariant as compared below:

| cd /SCRATCH/vgupta/gnu/install-glibc-A-baseline
| for i in `find . -name libm-2.31.9000.so`; do
|   echo $i; diff $i /SCRATCH/vgupta/gnu/install-glibc-C-reduce-scope/$i ;
|   echo $?;
| done

[PATCH v3 4/4] powerpc/fpu: use generic fma functions

[Vineet Gupta]

Tested with build-many-glibcs for powerpc-linux-gnu

This is a non functional change and powerpc libm before/after was
byte invariant as compared below:
