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 infor-
       mation 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.
