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
