[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 input address is printed on separate lines.
If the -f option is used, then each FILENAME:LINENO line is preceded by
FUNCTIONNAME which is the name of the function containing the address.
If the -i option is used and the code at the given address is present
there because of inlining by the compiler then the {FUNCTIONNAME}
FILENAME:LINENO information for the inlining function will be displayed
afterwards. This continues recursively until there is no more inlining
to report.
If the -a option is used then the output is prefixed by the input
address.
If the -p option is used then the output for each input address is
displayed on one, possibly quite long, line. If -p is not used then
the output is broken up into multiple lines, based on the paragraphs
above.
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.
OPTIONS
The long and short forms of options, shown here as alternatives, are
equivalent.
-a
--addresses
Display the address before the function name, file and line number
information. The address is printed with a 0x prefix to easily
identify it.
-b bfdname
--target=bfdname
Specify that the object-code format for the object files is
bfdname.
-C
--demangle[=style]
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
--exe=filename
Specify the name of the executable for which addresses should be
translated. The default file is a.out.
-f
--functions
Display function names as well as file and line number information.
-s
--basenames
Display only the base of each file name.
-i
--inlines
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.
-j
--section
Read offsets relative to the specified section instead of absolute
addresses.
-p
--pretty-print
Make the output more human friendly: each location are printed on
one line. If option -i is specified, lines for all enclosing
scopes are prefixed with (inlined by).
@file
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.
