powerpc: Move around math-related Implies Currently, powerpc, powerpc64, and powerpc64le imply the same set of subdirectories from sysdeps/ieee754: flt-32, dbl-64, ldbl-128ibm, and ldbl-opt. In preparation for the transition of the long double format - from IBM Extended Precision to IEEE 754 128-bits floating-point - on powerpc64le, this patch splits the shared Implies file into three separate files (one for each of the powerpc architectures), without changing their contents. Future patches will modify powerpc64le. * sysdeps/powerpc/Implies: Removed.

powerpc64le: Enable support for IEEE long double On platforms where long double may have two different formats, i.e.: the same format as double (64-bits) or something else (128-bits), building with -mlong-double-128 is the default and function calls in the user program match the name of the function in Glibc. When building with -mlong-double-64, Glibc installed headers redirect such calls to the appropriate function. Likewise, the internals of glibc are now built against IEEE long double. However, the only (minimally) notable usage of long double is difftime. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com> 2019-07-11 22:48:28 +08:00			`ieee754/ldbl-128ibm-compat`

powerpc64le: Enable float128 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. 2016-08-10 05:48:54 +08:00			`ieee754/float128`
