                 [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.

       -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.

       @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.
