It does fail but not in the # right way. That is it SEGVs trying to load from the opd at BAD_NIP, # but it never gets as far as branching to BAD_NIP. # # To fix it we need to create an opd which is reachable but which holds # the bad address. # # Fixes: b7683fc66eba ("selftests/powerpc: Add a test of wild bctr") # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version #
