addr2line - convert addresses into file names and line numbers.
addr2line [-b bfdname|--target=bfdname]
[addr addr ...]
addr2line translates program addresses into file names and line num-
bers. Given an address and an executable, it uses the debugging infor-
mation 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 con-
vert 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 FUNC-
TIONNAME 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.
The long and short forms of options, shown here as alternatives, are
Specify that the object-code format for the object files is bfd-
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 com-
Display function names as well as file and line number information.
Display only the base of each file name.
