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 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.
