19 addr2line translates addresses into file names and line numbers. Given
20 an address in an executable or an offset in a section of a relocatable
21 object, it uses the debugging information to figure out which file name
22 and line number are associated with it.
23 The executable or relocatable object to use is specified with the -e
25 option. The default is the file a.out. The section in the relocatable
26 object to use is specified with the -j option.
27 addr2line has two modes of operation.
29 In the first, hexadecimal addresses are specified on the command line,
31 and addr2line displays the file name and line number for each address.
32 In the second, addr2line reads hexadecimal addresses from standard
34 input, and prints the file name and line number for each address on
35 standard output. In this mode, addr2line may be used in a pipe to
36 convert dynamically chosen addresses.
37 The format of the output is FILENAME:LINENO. The file name and line
39 number for each address is printed on a separate line. If the -f
40 option is used, then each FILENAME:LINENO line is preceded by a
41 FUNCTIONNAME line which is the name of the function containing the
42 address.
43 If the file name or function name can not be determined, addr2line will
45 print two question marks in their place. If the line number can not be
46 determined, addr2line will print 0.
47
49 The long and short forms of options, shown here as alternatives, are
50 equivalent.
51 -b bfdname
53 --target=bfdname
54 Specify that the object-code format for the object files is
55 bfdname.
56 -C
58 --demangle[=style]
59 Decode (demangle) low-level symbol names into user-level names.
60 Besides removing any initial underscore prepended by the system,
61 this makes C++ function names readable. Different compilers have
62 different mangling styles. The optional demangling style argument
63 can be used to choose an appropriate demangling style for your
64 compiler.
65 -e filename
67 --exe=filename
68 Specify the name of the executable for which addresses should be
69 translated. The default file is a.out.
70 -f
72 --functions
73 Display function names as well as file and line number information.
74 -s
76 --basenames
77 Display only the base of each file name.
78 -i
80 --inlines
81 If the address belongs to a function that was inlined, the source
82 information for all enclosing scopes back to the first non-inlined
83 function will also be printed. For example, if "main" inlines
84 "callee1" which inlines "callee2", and address is from "callee2",
85 the source information for "callee1" and "main" will also be
86 printed.
87 -j
89 --section
90 Read offsets relative to the specified section instead of absolute
91 addresses.
92 @file
94 Read command-line options from file. The options read are inserted
95 in place of the original @file option. If file does not exist, or
96 cannot be read, then the option will be treated literally, and not
97 removed.
98 Options in file are separated by whitespace. A whitespace
100 character may be included in an option by surrounding the entire
101 option in either single or double quotes. Any character (including
102 a backslash) may be included by prefixing the character to be
103 included with a backslash. The file may itself contain additional
104 @file options; any such options will be processed recursively.
