DESCRIPTION

       GNU  nm  lists the symbols from object files objfile....  If no object files are listed as
       arguments, nm assumes the file a.out.

       For each symbol, nm shows:

       •   The symbol value, in the radix selected by options  (see  below),  or  hexadecimal  by
           default.

       •   The  symbol  type.   At  least  the  following  types  are  used; others are, as well,
           depending on the object file format.  If lowercase, the symbol is local; if uppercase,
           the symbol is global (external).

           "A" The symbol's value is absolute, and will not be changed by further linking.

           "B" The symbol is in the uninitialized data section (known as BSS).

           "C" The  symbol  is  common.   Common  symbols  are uninitialized data.  When linking,
               multiple common symbols may appear with the same name.  If the symbol  is  defined
               anywhere, the common symbols are treated as undefined references.

           "D" The symbol is in the initialized data section.

           "G" The  symbol is in an initialized data section for small objects.  Some object file
               formats permit more efficient access to small data objects, such as a  global  int
               variable as opposed to a large global array.

           "I" The symbol is an indirect reference to another symbol.  This is a GNU extension to
               the a.out object file format which is rarely used.

           "N" The symbol is a debugging symbol.

           "R" The symbol is in a read only data section.

           "S" The symbol is in an uninitialized data section for small objects.

           "T" The symbol is in the text (code) section.

           "U" The symbol is undefined.

           "V" The symbol is a weak object.  When a weak defined symbol is linked with  a  normal
               defined  symbol,  the  normal  defined  symbol is used with no error.  When a weak
               undefined symbol is linked and the symbol is not defined, the value  of  the  weak
               symbol becomes zero with no error.

           "W" The symbol is a weak symbol that has not been specifically tagged as a weak object
               symbol.  When a weak defined symbol is linked with a normal  defined  symbol,  the
               normal  defined  symbol  is  used  with no error.  When a weak undefined symbol is
               linked and the symbol is not defined, the value of the symbol is determined  in  a
               system-specific manner without error.  On some systems, uppercase indicates that a
               default value has been specified.

           "-" The symbol is a stabs symbol in an a.out object file.   In  this  case,  the  next
               values printed are the stabs other field, the stabs desc field, and the stab type.
               Stabs symbols are used to hold debugging information.

           "?" The symbol type is unknown, or object file format specific.

       •   The symbol name.

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 (or archive member) in which it  was
           found, rather than identifying the input file once only, before all of its symbols.

       -a
       --debug-syms
           Display all symbols, even debugger-only symbols; normally these are not listed.

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

       -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.

       --no-demangle
           Do not demangle low-level symbol names.  This is the default.

       -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
       --format=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.

       -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  symbol,  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.

       -n
       -v
       --numeric-sort
           Sort  symbols  numerically  by  their  addresses,  rather than alphabetically by their
           names.

       -p
       --no-sort
           Do not bother to sort the symbols in any order; 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-size
           Print size, not the value, of defined symbols for the "bsd" output format.

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

       -r
       --reverse-sort
           Reverse the order 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.  If  the  "bsd"  output
           format  is  used the size of the symbol is printed, rather than the value, and -S must
           be used in order both size and value to be printed.

       --special-syms
           Display symbols which have a  target-specific  special  meaning.   These  symbols  are
           usually  used  by  the target for some special processing and are not normally helpful
           when included included in the normal symbol lists.  For example for ARM  targets  this
           option  would  skip  the  mapping  symbols used to mark transistions between ARM code,
           THUMB code and data.

       -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.

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

       --defined-only
           Display only defined symbols for each object file.

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

       -X  This  option  is  ignored  for compatibility with the AIX version of nm.  It takes one
           parameter which must be the string 32_64.  The default mode of AIX nm  corresponds  to
           -X 32, which is not supported by GNU nm.

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