11 # This script emulates a little of the functionality of addr2line for
12 # those systems that don't have it. The only command line argument is
13 # an executable name. The script reads hexadecimal addresses from
14 # stdin and prints the corresponding symbol names to stdout. The
15 # addresses must begin with "0x" and be fully zero filled or this
16 # won't work.
