addr2line - convert addresses into file names and line
numbers.
SYNOPSIS
addr2line [ -b bfdname | --target=bfdname ]
[ -C | --demangle[=style ]
[ -e filename | --exe=filename ]
[ -f | --functions ] [ -s | --basename ]
[ -H | --help ] [ -V | --version ]
[ addr addr ... ]
DESCRIPTION
`addr2line' translates program addresses into file names
and line numbers. Given an address and an executable, it
uses the debugging information in the executable to figure
out which file name and line number are associated with a
given address.
The executable to use is specified with the `-e' option.
The default is the file a.out.
`addr2line' has two modes of operation.
In the first, hexadecimal addresses are specified on the
command line, and `addr2line' displays the file name and
line number for each address.
In the second, `addr2line' reads hexadecimal addresses
from standard input, and prints the file name and line
number for each address on standard output. In this mode,
`addr2line' may be used in a pipe to convert dynamically
chosen addresses.
The format of the output is FILENAME:LINENO. The file
name and line number for each address is printed on a sep
arate line. If the `-f' option is used, then each FILE
NAME:LINENO line is preceded by a FUNCTIONNAME line which
is the name of the function containing the address.
If the file name or function name can not be determined,
`addr2line' will print two question marks in their place.
If the line number can not be determined, `addr2line' will
print 0.
OPTIONS
The long and short forms of options, shown here as alter
natives, are equivalent.
`-b bfdname'
`--target=bfdname'
Specify that the object-code format for the object
files is bfdname.
`--demangle[=style]'
Decode (demangle) low-level symbol names into user-
level names. Besides removing any initial underscore
prepended by the system, this makes C++ function names
readable. Different compilers have different mangling
styles. The optional demangling style argument can be
used to choose an appropriate demangling style for
your compiler.
`-e filename'
`--exe=filename'
Specify the name of the executable for which addresses
should be translated. The default file is a.out.
`-f'
`--functions'
Display function names as well as file and line number
information.
`-s'
`--basenames'
Display only the base of each file name.
