DESCRIPTION         top

       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.

OPTIONS         top

       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.
