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.
