	      format|--format=format] [--target=bfdname] [objfile...]

DESCRIPTION
       GNU nm lists the symbols from object files objfile.  If no object files
       are given as arguments, nm assumes `a.out'.

OPTIONS
       The  long  and  short forms of options, shown here as alternatives, are
       equivalent.

       -A

       -o

       --print-file-name
	      Precede each symbol by the name of the input file where  it  was
	      found,  rather  than identifying the input file once only before
	      all of its symbols.

       -a

       --debug-syms
	      Display debugger-only symbols; normally these are not listed.

       -B     The same as --format=bsd (for compatibility with the MIPS nm).

       -C

       --demangle
	      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.

       -D

       --dynamic
	      Display the dynamic symbols  rather  than  the  normal  symbols.
	      This  is	only  meaningful  for dynamic objects, such as certain
	      types of shared libraries.

       -f format
	      Use the output format format, which can be ``bsd'', ``sysv'', or
	      ``posix''.  The default is ``bsd''.  Only the first character of
	      format is significant; it can be either upper or lower case.

       -g

       --extern-only
	      Display only external symbols.

       -n

       -v

       --numeric-sort
	      Sort symbols numerically by their addresses, not	alphabetically
	      by their names.

       -p

       --no-sort
	      Don't  bother  to sort the symbols in any order; just print them
	      in the order encountered.

       -P

       --portability
	      Use the POSIX.2 standard output format instead  of  the  default
	      format.  Equivalent to ``-f posix''.

       -s

       --print-armap
	      When  listing symbols from archive members, include the index: a
	      mapping (stored in the archive by ar or ranlib) of what  modules
	      contain definitions for what names.

       -r

       --reverse-sort
	      Reverse  the  sense of the sort (whether numeric or alphabetic);
	      let the last come first.

       --size-sort
	      Sort symbols by size.  The size is computed  as  the  difference
	      between the value of the symbol and the value of the symbol with
	      the next higher value.  The  size  of  the  symbol  is  printed,
	      rather than the value.

       -t radix

       --radix=radix
	      Use  radix as the radix for printing the symbol values.  It must
	      be ``d'' for decimal, ``o'' for octal, or ``x'' for hexadecimal.

       --target=bfdname
	      Specify  an  object code format other than your system's default
	      format.  See objdump(1), for information	on  listing  available
	      formats.

       -u

       --undefined-only
	      Display  only  undefined	symbols (those external to each object
	      file).

       -l

       --line-numbers
	      For each symbol, use debugging information  to  try  to  find  a
	      filename	and  line  number.  For a defined symbol, look for the
	      line number of the address of the symbol.  For an undefined sym-
	      bol, look for the line number of a relocation entry which refers
	      to the symbol.  If line number information can be  found,  print
	      it after the other symbol information.

       -V

       --version
	      Show the version number of nm and exit.

       --help Show a summary of the options to nm and exit.
