Описание (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. By default each
input address generates one line of output.
Two options can generate additional lines before each
FILENAME:LINENO line (in that order).
If the -a option is used then a line with the input address is
displayed.
If the -f option is used, then a line with the FUNCTIONNAME is
displayed. This is the name of the function containing the
address.
One option can generate additional lines after the
FILENAME:LINENO line.
If the -i option is used and the code at the given address is
present there because of inlining by the compiler then additional
lines are displayed afterwards. One or two extra lines (if the
-f option is used) are displayed for each inlined function.
Alternatively if the -p option is used then each input address
generates a single, long, output line containing the address, the
function name, the file name and the line number. If the -i
option has also been used then any inlined functions will be
displayed in the same manner, but on separate lines, and prefixed
by the text (inlined by).
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.
Параметры (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).
-r
-R
--recurse-limit
--no-recurse-limit
--recursion-limit
--no-recursion-limit
Enables or disables a limit on the amount of recursion
performed whilst demangling strings. Since the name mangling
formats allow for an infinite level of recursion it is
possible to create strings whose decoding will exhaust the
amount of stack space available on the host machine,
triggering a memory fault. The limit tries to prevent this
from happening by restricting recursion to 2048 levels of
nesting.
The default is for this limit to be enabled, but disabling it
may be necessary in order to demangle truly complicated
names. Note however that if the recursion limit is disabled
then stack exhaustion is possible and any bug reports about
such an event will be rejected.
The -r option is a synonym for the --no-recurse-limit option.
The -R option is a synonym for the --recurse-limit option.
Note this option is only effective if the -C or --demangle
option has been enabled.
@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.
