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 input address is printed on separate lines.
42 If the -f option is used, then each FILENAME:LINENO line is preceded by
44 FUNCTIONNAME which is the name of the function containing the address.
45 If the -i option is used and the code at the given address is present
47 there because of inlining by the compiler then the {FUNCTIONNAME}
48 FILENAME:LINENO information for the inlining function will be displayed
49 afterwards. This continues recursively until there is no more inlining
50 to report.
51 If the -a option is used then the output is prefixed by the input
53 address.
54 If the -p option is used then the output for each input address is
56 displayed on one, possibly quite long, line. If -p is not used then
57 the output is broken up into multiple lines, based on the paragraphs
58 above.
59 If the file name or function name can not be determined, addr2line will
61 print two question marks in their place. If the line number can not be
62 determined, addr2line will print 0.
63
65 The long and short forms of options, shown here as alternatives, are
66 equivalent.
67 -a
69 --addresses
70 Display the address before the function name, file and line number
71 information. The address is printed with a 0x prefix to easily
72 identify it.
73 -b bfdname
75 --target=bfdname
76 Specify that the object-code format for the object files is
77 bfdname.
78 -C
80 --demangle[=style]
81 Decode (demangle) low-level symbol names into user-level names.
82 Besides removing any initial underscore prepended by the system,
83 this makes C++ function names readable. Different compilers have
84 different mangling styles. The optional demangling style argument
85 can be used to choose an appropriate demangling style for your
86 compiler.
87 -e filename
89 --exe=filename
90 Specify the name of the executable for which addresses should be
91 translated. The default file is a.out.
92 -f
94 --functions
95 Display function names as well as file and line number information.
96 -s
98 --basenames
99 Display only the base of each file name.
100 -i
102 --inlines
103 If the address belongs to a function that was inlined, the source
104 information for all enclosing scopes back to the first non-inlined
105 function will also be printed. For example, if "main" inlines
106 "callee1" which inlines "callee2", and address is from "callee2",
107 the source information for "callee1" and "main" will also be
108 printed.
109 -j
111 --section
112 Read offsets relative to the specified section instead of absolute
113 addresses.
114 -p
116 --pretty-print
117 Make the output more human friendly: each location are printed on
118 one line. If option -i is specified, lines for all enclosing
119 scopes are prefixed with (inlined by).
120 @file
122 Read command-line options from file. The options read are inserted
123 in place of the original @file option. If file does not exist, or
124 cannot be read, then the option will be treated literally, and not
125 removed.
126 Options in file are separated by whitespace. A whitespace
128 character may be included in an option by surrounding the entire
129 option in either single or double quotes. Any character (including
130 a backslash) may be included by prefixing the character to be
131 included with a backslash. The file may itself contain additional
132 @file options; any such options will be processed recursively.
