NAME
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 separate line. If the -f option is used, then each
FILENAME: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 alternatives, are equivalent.

-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 remov-
ing 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 deman-
gling 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.
