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