This patch adds ULPs for the float128 type, updates the abilist for libc and libm, and adds the files bits/floatn.h and float128-abi.h, in order to enable the new type for powerpc64le. This patch also adds the implementation of sqrtf128 for powerpc64le, since it is not implemented in libgcc. The sfp-machine.h header is taken from libgcc. Tested for powerpc64le (GCC 6.2 and GCC 7.1), powerpc64 and s390x. * manual/math.texi (Mathematics): Mention the enabling of float128 for powerpc64le. * sysdeps/powerpc/bits/floatn.h: New file. * sysdeps/powerpc/fpu/libm-test-ulps: Regenerated. * sysdeps/powerpc/fpu/math_private.h: (__ieee754_sqrtf128): New inline override. * sysdeps/powerpc/powerpc64le/Implies-before: New file. * sysdeps/powerpc/powerpc64le/Makefile: New file. * sysdeps/powerpc/powerpc64le/fpu/e_sqrtf128.c: New file. * sysdeps/powerpc/powerpc64le/fpu/sfp-machine.h: New file. * sysdeps/powerpc/powerpc64le/power9/fpu/e_sqrtf128.c: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist: Updated. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64le/float128-abi.h: New file.
