21 addr2line translates addresses into file names and line numbers. Given
22 an address in an executable or an offset in a section of a relocatable
23 object, it uses the debugging information to figure out which file name
24 and line number are associated with it.
25 The executable or relocatable object to use is specified with the -e
27 option. The default is the file a.out. The section in the relocatable
28 object to use is specified with the -j option.
29 addr2line has two modes of operation.
31 In the first, hexadecimal addresses are specified on the command line,
33 and addr2line displays the file name and line number for each address.
34 In the second, addr2line reads hexadecimal addresses from standard
36 input, and prints the file name and line number for each address on
37 standard output. In this mode, addr2line may be used in a pipe to
38 convert dynamically chosen addresses.
39 The format of the output is FILENAME:LINENO. The file name and line
41 number for each address is printed on a separate line. If the -f
42 option is used, then each FILENAME:LINENO line is preceded by a
43 FUNCTIONNAME line which is the name of the function containing the
44 address. If the -a option is used, then the address read is first
45 printed.
46 If the file name or function name can not be determined, addr2line will
48 print two question marks in their place. If the line number can not be
49 determined, addr2line will print 0.

52 The long and short forms of options, shown here as alternatives, are
53 equivalent.
54 -a
56 --addresses
57 Display address before function names or file and line number
58 information. The address is printed with a 0x prefix to easily
59 identify it.
60 -b bfdname
62 --target=bfdname
63 Specify that the object-code format for the object files is
64 bfdname.
65 -C
67 --demangle[=style]
68 Decode (demangle) low-level symbol names into user-level names.
69 Besides removing any initial underscore prepended by the system,
70 this makes C++ function names readable. Different compilers have
71 different mangling styles. The optional demangling style argument
72 can be used to choose an appropriate demangling style for your
73 compiler.
74 -e filename
76 --exe=filename
77 Specify the name of the executable for which addresses should be
78 translated. The default file is a.out.
79 -f
81 --functions
82 Display function names as well as file and line number information.
83 -s
85 --basenames
86 Display only the base of each file name.
87 -i
89 --inlines
90 If the address belongs to a function that was inlined, the source
91 information for all enclosing scopes back to the first non-inlined
92 function will also be printed. For example, if "main" inlines
93 "callee1" which inlines "callee2", and address is from "callee2",
94 the source information for "callee1" and "main" will also be
95 printed.
96 -j
98 --section
99 Read offsets relative to the specified section instead of absolute
100 addresses.
101 -p
103 --pretty-print
104 Make the output more human friendly: each location are printed on
105 one line. If option -i is specified, lines for all enclosing
106 scopes are prefixed with (inlined by).
107 @file
109 Read command-line options from file. The options read are inserted
110 in place of the original @file option. If file does not exist, or
111 cannot be read, then the option will be treated literally, and not
112 removed.
113 Options in file are separated by whitespace. A whitespace
115 character may be included in an option by surrounding the entire
116 option in either single or double quotes. Any character (including
117 a backslash) may be included by prefixing the character to be
118 included with a backslash. The file may itself contain additional
119 @file options; any such options will be processed recursively.
