# PowerPC floating point little-endian [12 of 15]
# http://sourceware.org/ml/libc-alpha/2013-08/msg00087.html

# Fixes for little-endian in 32-bit assembly.
#
# * sysdeps/powerpc/sysdep.h (LOWORD, HIWORD, HISHORT): Define.
# * sysdeps/powerpc/powerpc32/fpu/s_copysign.S: Load little-endian
# words of double from correct stack offsets.
