NAMEaddr2line - convert addresses into file names and line numbers.
SYNOPSISaddr2line [-b bfdname|--target=bfdname]
[addr addr ...]
DESCRIPTIONaddr2line translates addresses into file names and line numbers. Given an address in an executable or an offset in a section of a relocatable object, it uses the debugging information to figure out which file name and line number are associated with it.
The executable or relocatable object to use is specified with the -e option. The default is the file a.out. The section in the relocatable object to use is specified with the -j option.
addr2line has two modes of operation.
In the first, hexadecimal addresses are specified on the command line, and addr2line displays the file name and line number for each address.
In the second, addr2line reads hexadecimal addresses from standard input, and prints the file name and line number for each address on standard output. In this mode, addr2line may be used in a pipe to convert dynamically chosen addresses.
The format of the output is FILENAME:LINENO. The file name and line number for each address is printed on a separate line. If the -f option is used, then each FILENAME:LINENO line is preceded by a FUNCTIONNAME line which is the name of the function containing the address.
OPTIONSThe long and short forms of options, shown here as alternatives, are equivalent.
- -b bfdname
- Specify that the object-code format for the object files is bfdname.
- Decode (demangle) low-level symbol names into user-level names. Besides removing any initial underscore prepended by the system, this makes C++ function names readable. Different compilers have different mangling styles. The optional demangling style argument can be used to choose an appropriate demangling style for your compiler.
- -e filename
- Specify the name of the executable for which addresses should be translated. The default file is a.out.
- Display function names as well as file and line number information.
- Display only the base of each file name.
- If the address belongs to a function that was inlined, the source information for all enclosing scopes back to the first non-inlined function will also be printed. For example, if "main" inlines "callee1" which inlines "callee2", and address is from "callee2", the source information for "callee1" and "main" will also be printed.
- Read offsets relative to the specified section instead of absolute addresses.
Read command-line options from file. The options read are
inserted in place of the original @file option. If file
does not exist, or cannot be read, then the option will be treated
literally, and not removed.
Options in file are separated by whitespace. A whitespace character may be included in an option by surrounding the entire option in either single or double quotes. Any character (including a backslash) may be included by prefixing the character to be included with a backslash. The file may itself contain additional @file options; any such options will be processed recursively.
