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.
