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. By default each input
41 address generates one line of output.
42 Two options can generate additional lines before each FILENAME:LINENO
44 line (in that order).
45 If the -a option is used then a line with the input address is
47 displayed.
48 If the -f option is used, then a line with the FUNCTIONNAME is
50 displayed. This is the name of the function containing the address.
51 One option can generate additional lines after the FILENAME:LINENO
53 line.
54 If the -i option is used and the code at the given address is present
56 there because of inlining by the compiler then additional lines are
57 displayed afterwards. One or two extra lines (if the -f option is
58 used) are displayed for each inlined function.
59 Alternatively if the -p option is used then each input address
61 generates a single, long, output line containing the address, the
62 function name, the file name and the line number. If the -i option has
63 also been used then any inlined functions will be displayed in the same
64 manner, but on separate lines, and prefixed by the text (inlined by).
65 If the file name or function name can not be determined, addr2line will
67 print two question marks in their place. If the line number can not be
68 determined, addr2line will print 0.

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