ADDR2LINE(1) GNU Development Tools ADDR2LINE(1)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 con‐
vert 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 FUNC‐
TIONNAME line which is the name of the function containing the address.
If the file name or function name can not be determined, addr2line will
print two question marks in their place. If the line number can not be
determined, addr2line will print 0.
The long and short forms of options, shown here as alternatives, are
Specify that the object-code format for the object files is bfd‐
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 com‐
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
Read offsets relative to the specified section instead of absolute
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
Options in file are separated by whitespace. A whitespace charac‐
ter 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.
