# commit 4ebd120cd983c8d2ac7a234884b3ac6805d82973
# Author: Alan Modra <amodra@gmail.com>
# Date: Sat Aug 17 18:24:05 2013 +0930
#
# 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.
