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 num-
      ber 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 sep-
      arate 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 sur-
          rounding 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.
