# commit 9b874b2f1eb2550e39d3e9c38772e64a767e9de2
# Author: Alan Modra <amodra@gmail.com>
# Date: Sat Aug 17 18:35:40 2013 +0930
#
# PowerPC ugly symbol versioning
# http://sourceware.org/ml/libc-alpha/2013-08/msg00090.html
#
# This patch fixes symbol versioning in setjmp/longjmp. The existing
# code uses raw versions, which results in wrong symbol versioning when
# you want to build glibc with a base version of 2.19 for LE.
#
# Note that the merging the 64-bit and 32-bit versions in novmx-lonjmp.c
# and pt-longjmp.c doesn't result in GLIBC_2.0 versions for 64-bit, due
# to the base in shlib_versions.
#
# * sysdeps/powerpc/longjmp.c: Use proper symbol versioning macros.
# * sysdeps/powerpc/novmx-longjmp.c: Likewise.
# * sysdeps/powerpc/powerpc32/bsd-_setjmp.S: Likewise.
# * sysdeps/powerpc/powerpc32/bsd-setjmp.S: Likewise.
# * sysdeps/powerpc/powerpc32/fpu/__longjmp.S: Likewise.
# * sysdeps/powerpc/powerpc32/fpu/setjmp.S: Likewise.
# * sysdeps/powerpc/powerpc32/mcount.c: Likewise.
# * sysdeps/powerpc/powerpc32/setjmp.S: Likewise.
# * sysdeps/powerpc/powerpc64/setjmp.S: Likewise.
# * nptl/sysdeps/unix/sysv/linux/powerpc/pt-longjmp.c: Likewise.
