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. Previous contents copied to...
* sysdeps/powerpc/powerpc32/Implies-after: ... here.
* sysdeps/powerpc/powerpc64/be/Implies-after: ... here.
* sysdeps/powerpc/powerpc64/le/Implies-before: ... and here.
