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.
