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]
                 [-i|--inlines]
                 [-j|--section=name]
                 [-H|--help] [-V|--version]
                 [addr addr ...]

DESCRIPTION

       addr2line translates addresses into file names and line numbers.  Given an address in an executable or an
       offset in a section of a relocatable object, it uses the debugging information to figure out  which  file
       name and line number are associated with it.

       The  executable  or  relocatable  object to use is specified with the -e option.  The default is the file
       a.out.  The section in the relocatable object to use is specified with the -j option.

       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.

       -j
       --section
           Read offsets relative to the specified section instead of absolute addresses.

       @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.
