  36 .SH DESCRIPTION
  37 \c
  38 .B addr2line
  39 translates program addresses into file names and line numbers.  Given
  40 an address and an executable, it uses the debugging information in the
  41 executable to figure out which file name and line number are
  42 associated with a given address.
  43
  44 The executable to use is specified with the
  45 .B \-e
  46 option.  The default is
  47 .B a.out\c
  48 \&.
  49
  50 .B addr2line
  51 has two modes of operation.
  52
  53 In the first, hexadecimal addresses are specified on the command line,
  54 and
  55 .B addr2line
  56 displays the file name and line number for each address.
  57
  58 In the second,
  59 .B addr2line
  60 reads hexadecimal addresses from standard input, and prints the file
  61 name and line number for each address on standard output.  In this
  62 mode,
  63 .B addr2line
  64 may be used in a pipe to convert dynamically chosen addresses.
  65
  66 The format of the output is FILENAME:LINENO.  The file name and line
  67 number for each address is printed on a separate line.  If the
  68 .B \-f
  69 option is used, then each FILENAME:LINENO line is preceded by a
  70 FUNCTIONNAME line which is the name of the function containing the
  71 address.
  72
  73 If the file name or function name can not be determined,
  74 .B addr2line
  75 will print two question marks in their place.  If the line number can
  76 not be determined,
  77 .B addr2line
  78 will print 0.

  80 .SH OPTIONS
  81 .TP
  82 .BI "\-b " "bfdname"\c
  83 .TP
  84 .BI "\-\-target=" "bfdname"
  85 Specify the object-code format for the object files to be
  86 \c
  87 .I bfdname\c
  88 \&.
  89
  90 .TP
  91 .B \-C
  92 .TP
  93 .B \-\-demangle
  94 Decode (\fIdemangle\fP) low-level symbol names into user-level names.
  95 Besides removing any initial underscore prepended by the system, this
  96 makes C++ function names readable.
  97
  98 .TP
  99 .BI "\-e " "filename"\c
 100 .TP
 101 .BI "\-\-exe=" "filename"
 102 Specify the name of the executable for which addresses should be
 103 translated.  The default file is
 104 .B a.out\c
 105 \&.
 106
 107 .TP
 108 .B \-f
 109 .TP
 110 .B \-\-functions
 111 Display function names as well as file and line number information.
 112
 113 .TP
 114 .B \-s
 115 .TP
 116 .B \-\-basenames
 117 Display only the base of each file name.
