addr2line − convert addresses into file names and line
numbers.

addr2line [−b bfdname−−target=bfdname]
          [−C−−demangle[=style]]
          [−e filename−−exe=filename]
          [−f−−functions] [−s−−basename]
          [−H−−help] [−V−−version]
          [addr addr ...]

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.

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











                             ‐2‐


−−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.
