addr2line -- translate program addresses to source file names and line numbers
SYNOPSIS
addr2line [-b target | --target=target] [-e pathname | --exe=pathname] [-f | --functions] [-j sectionname | --section=sectionname]
[-s | --basename] [-C | --demangle] [-H | --help] [-V | --version] [hexaddress...]
DESCRIPTION
The addr2line utility translates program addresses specified by the command line arguments hexaddress to their corresponding source file
names and line numbers. If no arguments are given to addr2line, it will read these addresses from standard input.
Program addresses specified by arguments hexaddress are encoded using the conventions accepted by strtoull(3).
By default, addr2line will use the executable ``a.out''. The -e option may be used to specified a different ELF object.
The addr2line utility recognizes the following options:
-b target | --target=target
This option is recognized by addr2line but is ignored. It is supported for compatibility with GNU binutils.
-e pathname | --exe=pathname
Use the ELF object specified by argument pathname to translate addresses. If this option is not specified, addr2line will use the
file ``a.out''.
-f | --functions
Display function names in addition to file and line number information.
-j sectionname | --section=sectionname
The values specified by arguments hexaddress are to be treated as offsets into the section named sectionname.
-s | --basename
Display only the base name for each file name.
-C | --demangle
Demangle C++ names.
-H | --help
Print a help message.
-V | --version
Print a version identifier and exit.
OUTPUT FORMAT
If the -f option was not specified, addr2line will print the file name and line number for each address specified on a separate line.
If the -f option was specified, addr2line will print a line containing the name of the function corresponding to program address hexaddress,
followed by a line with the file name and line number.
The addr2line utility prints the file name and line number using the format ``FILENAME:LINENUMBER''.
If a file or function name could not be determined, addr2line will print a question mark in their place. If the line number could not be
determined, addr2line will print a zero in its place.
EXAMPLES
To map address 080483c4 in the default executable a.out to a source file name and line number use:
% addr2line 080483c4
To map address 080483c4 in executable helloworld, use:
% addr2line -e helloworld 080483c4
To have addr2line act as a filter reading addresses from its standard input use:
% addr2line
To print the function name corresponding to an address in addition to its source file and line number use:
% addr2line -f 080483c4
EXIT STATUS
The addr2line utility exits 0 on success, and >0 if an error occurs.

addr2line - convert addresses into file names and line numbers.
SYNOPSIS
addr2line [-b bfdname|--target=bfdname]
[-C|--demangle[=style]]
[-e filename|--exe=filename]
[-f|--functions] [-s|--basename]
[-i|--inlines]
[-j|--section=name]
[-H|--help] [-V|--version]
[addr addr ...]
DESCRIPTION
addr2line translates addresses into file names and line numbers. Given an address in an executable or an offset in a section of a relocat-
able 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 relocat-
able 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 address is printed on a separate line. If the -f
option is used, then each FILENAME:LINENO line is preceded by a FUNCTIONNAME 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.
OPTIONS
The long and short forms of options, shown here as alternatives, are equivalent.
-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.
@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.
