description
addr2line
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.
--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.
--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.
--functions
Display function names as well
as file and line number information.
--basenames
Display only the base of each
file name.
--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.
--section
Read offsets relative to the
specified section instead of absolute addresses.
--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.
