DESCRIPTION
addr2line translates addresses into file names and line
numbers. Given an address in an executable or an offset in
a section of a relocatable object, it uses the debugging
information to figure out which file name and line number
are associated with it.
The executable or relocatable object to use is specified
with the -e option. The default is the file a.out. The
section in the relocatable object to use is specified with
the -j option.
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 input address is printed on
separate lines.
If the -f option is used, then each FILENAME:LINENO line is
preceded by FUNCTIONNAME which is the name of the function
containing the address.
If the -i option is used and the code at the given address
is present there because of inlining by the compiler then
the {FUNCTIONNAME} FILENAME:LINENO information for the
inlining function will be displayed afterwards. This

continues recursively until there is no more inlining to
report.
If the -a option is used then the output is prefixed by the
input address.
If the -p option is used then the output for each input
address is displayed on one, possibly quite long, line. If
-p is not used then the output is broken up into multiple
lines, based on the paragraphs above.
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
alternatives, are equivalent.
-a
--addresses
Display the address before the function name, file and
line number information. The address is printed with a
0x prefix to easily identify it.
-b bfdname
--target=bfdname
Specify that the object-code format for the object files
is bfdname.
-C
--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

GNU Development Tools ADDR2LINE(1)
--basenames
Display only the base of each file name.
-i
--inlines
If the address belongs to a function that was inlined,
the source information for all enclosing scopes back to
the first non-inlined function will also be printed.
For example, if "main" inlines "callee1" which inlines
"callee2", and address is from "callee2", the source
information for "callee1" and "main" will also be
printed.
-j
--section
Read offsets relative to the specified section instead
of absolute addresses.
-p
--pretty-print
Make the output more human friendly: each location are
printed on one line. If option -i is specified, lines
for all enclosing scopes are prefixed with (inlined by).
@file
Read command-line options from file. The options read
are inserted in place of the original @file option. If
file does not exist, or cannot be read, then the option
will be treated literally, and not removed.
Options in file are separated by whitespace. A
whitespace character may be included in an option by
surrounding the entire option in either single or double
quotes. Any character (including a backslash) may be
included by prefixing the character to be included with
a backslash. The file may itself contain additional
@file options; any such options will be processed
recursively.
