addr2line - convert addresses into file names and line numbers.
addr2line [-b bfdname|--target=bfdname]
[addr addr ...]
addr2line translates program addresses into file names and line numbers. Given an address
and an executable, it uses the debugging information in the executable to figure out which
file name and line number are associated with a given address.
The executable to use is specified with the -e option. The default is the file a.out.
addr2line has two modes of operation.
In the first, hexadecimal addresses are specified on the command line, and addr2line dis-
plays 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 FILE-
NAME:LINENO line is preceded by a FUNCTIONNAME line which is the name of the function con-
taining 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 equivalent.
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.
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.
