IBM long double mechanical changes to support little-endian
http://sourceware.org/ml/libc-alpha/2013-07/msg00001.html This patch starts the process of supporting powerpc64 little-endian long double in glibc. IBM long double is an array of two ieee doubles, so making union ibm_extended_long_double reflect this fact is the correct way to access fields of the doubles. * sysdeps/ieee754/ldbl-128ibm/ieee754.h (union ibm_extended_long_double): Define as an array of ieee754_double. (IBM_EXTENDED_LONG_DOUBLE_BIAS): Delete. * sysdeps/ieee754/ldbl-128ibm/printf_fphex.c: Update all references to ibm_extended_long_double and IBM_EXTENDED_LONG_DOUBLE_BIAS. * sysdeps/ieee754/ldbl-128ibm/e_exp10l.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/e_expl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/ldbl2mpn.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h: Likewise. * sysdeps/ieee754/ldbl-128ibm/mpn2ldbl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nearbyintl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/strtold_l.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/x2y2m1l.c: Likewise.
