PowerPC floating point little-endian [2 of 15]
http://sourceware.org/ml/libc-alpha/2013-08/msg00082.html This patch replaces occurrences of GET_LDOUBLE_* and SET_LDOUBLE_* macros, and union ieee854_long_double_shape_type in ldbl-128ibm/, and a stray one in the 32-bit fpu support. These files have no significant changes apart from rewriting the long double bit access. * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h (ldbl_high): Define. * sysdeps/ieee754/ldbl-128ibm/e_acoshl.c (__ieee754_acoshl): Rewrite all uses of ieee854 long double macros and unions. * sysdeps/ieee754/ldbl-128ibm/e_acosl.c (__ieee754_acosl): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_asinl.c (__ieee754_asinl): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_atanhl.c (__ieee754_atanhl): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_coshl.c (__ieee754_coshl): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_log2l.c (__ieee754_log2l): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_rem_pio2l.c (__ieee754_rem_pio2l): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_sinhl.c (__ieee754_sinhl): Likewise. * sysdeps/ieee754/ldbl-128ibm/k_cosl.c (__kernel_cosl): Likewise. * sysdeps/ieee754/ldbl-128ibm/k_sincosl.c (__kernel_sincosl): Likewise. * sysdeps/ieee754/ldbl-128ibm/k_sinl.c (__kernel_sinl): Likewise. * sysdeps/ieee754/ldbl-128ibm/s_asinhl.c (__asinhl): Likewise. * sysdeps/ieee754/ldbl-128ibm/s_atanl.c (__atanl): Likewise.
