* scripts: add check_extable.sh script.Quentin Casasnovas2015-04-131-0/+146
This shell script can be used to sanity check the __ex_table section on an object file, making sure the relocations in there are pointing to valid executable sections. If it finds some suspicious relocations, it'll use addr2line to try and dump where this is coming from. This works best with CONFIG_DEBUG_INFO.
