# commit 43b84013714c46e6dcae4a5564c5527777ad5e08

# PowerPC LE strcpy
# http://sourceware.org/ml/libc-alpha/2013-08/msg00100.html
#
# The strcpy changes for little-endian are quite straight-forward, just
# a matter of rotating the last word differently.
#
# I'll note that the powerpc64 version of stpcpy is just begging to be
# converted to use 64-bit loads and stores..
#
# * sysdeps/powerpc/powerpc64/strcpy.S: Add little-endian support:
# * sysdeps/powerpc/powerpc32/strcpy.S: Likewise.
# * sysdeps/powerpc/powerpc64/stpcpy.S: Likewise.
# * sysdeps/powerpc/powerpc32/stpcpy.S: Likewise.
