 <p><small>GNU</small> <code>nm</code> lists the symbols from object files <var>objfile</var>&hellip;.
 If no object files are listed as arguments, <code>nm</code> assumes the file
 <samp>a.out</samp>.
 </p>
 <p>For each symbol, <code>nm</code> shows:
 </p>
 <ul>
 <li> The symbol value, in the radix selected by options (see below), or
 hexadecimal by default.

 </li><li> 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
 usually local; if uppercase, the symbol is global (external).  There
 are however a few lowercase symbols that are shown for special global
 symbols (<code>u</code>, <code>v</code> and <code>w</code>).

 <dl compact="compact">
 <dt><code>A</code></dt>
 <dd><p>The symbol&rsquo;s value is absolute, and will not be changed by further
 linking.
 </p>
 </dd>
 <dt><code>B</code></dt>
 <dt><code>b</code></dt>
 <dd><p>The symbol is in the uninitialized data section (known as BSS).
 </p>
 </dd>
 <dt><code>C</code></dt>
 <dd><p>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.
 For more details on common symbols, see the discussion of
 &ndash;warn-common in <a href="http://sourceware.org/binutils/docs/ld/Options.html#Options">Linker options</a> in <cite>The GNU linker</cite>.
 </p>
 </dd>
 <dt><code>D</code></dt>
 <dt><code>d</code></dt>
 <dd><p>The symbol is in the initialized data section.
 </p>
 </dd>
 <dt><code>G</code></dt>
 <dt><code>g</code></dt>
 <dd><p>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.
 </p>
 </dd>
 <dt><code>i</code></dt>
 <dd><p>For PE format files this indicates that the symbol is in a section
 specific to the implementation of DLLs.  For ELF format files this
 indicates that the symbol is an indirect function.  This is a GNU
 extension to the standard set of ELF symbol types.  It indicates a
 symbol which if referenced by a relocation does not evaluate to its
 address, but instead must be invoked at runtime.  The runtime
 execution will then return the value to be used in the relocation.
 </p>
 </dd>
 <dt><code>I</code></dt>
 <dd><p>The symbol is an indirect reference to another symbol.
 </p>
 </dd>
 <dt><code>N</code></dt>
 <dd><p>The symbol is a debugging symbol.
 </p>
 </dd>
 <dt><code>p</code></dt>
 <dd><p>The symbols is in a stack unwind section.
 </p>
 </dd>
 <dt><code>R</code></dt>
 <dt><code>r</code></dt>
 <dd><p>The symbol is in a read only data section.
 </p>
 </dd>
 <dt><code>S</code></dt>
 <dt><code>s</code></dt>
 <dd><p>The symbol is in an uninitialized data section for small objects.
 </p>
 </dd>
 <dt><code>T</code></dt>
 <dt><code>t</code></dt>
 <dd><p>The symbol is in the text (code) section.
 </p>
 </dd>
 <dt><code>U</code></dt>
 <dd><p>The symbol is undefined.
 </p>
 </dd>
 <dt><code>u</code></dt>
 <dd><p>The symbol is a unique global symbol.  This is a GNU extension to the
 standard set of ELF symbol bindings.  For such a symbol the dynamic linker
 will make sure that in the entire process there is just one symbol with
 this name and type in use.
 </p>
 </dd>
 <dt><code>V</code></dt>
 <dt><code>v</code></dt>
 <dd><p>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.  On some
 systems, uppercase indicates that a default value has been specified.
 </p>
 </dd>
 <dt><code>W</code></dt>
 <dt><code>w</code></dt>
 <dd><p>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.
 </p>
 </dd>
 <dt><code>-</code></dt>
 <dd><p>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.
 </p>
 </dd>
 <dt><code>?</code></dt>
 <dd><p>The symbol type is unknown, or object file format specific.

 <dt><code>--demangle[=<var>style</var>]</code></dt>
 <dd><a name="index-demangling-in-nm"></a>
 <p>Decode (<em>demangle</em>) 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. See <a href="c_002b_002bfilt.html#c_002b_002bfilt">c++filt</a>,
 for more information on demangling.
 </p>
 </dd>
 <dt><code>--no-demangle</code></dt>
 <dd><p>Do not demangle low-level symbol names.  This is the default.
 </p>
 </dd>
 <dt><code>-D</code></dt>
 <dt><code>--dynamic</code></dt>
 <dd><a name="index-dynamic-symbols"></a>
 <p>Display the dynamic symbols rather than the normal symbols.  This is
 only meaningful for dynamic objects, such as certain types of shared
 libraries.

 <dt><code>--format=<var>format</var></code></dt>
 <dd><a name="index-nm-format-1"></a>
 <a name="index-nm-compatibility-1"></a>
 <p>Use the output format <var>format</var>, which can be <code>bsd</code>,
 <code>sysv</code>, or <code>posix</code>.  The default is <code>bsd</code>.
 Only the first character of <var>format</var> is significant; it can be
 either upper or lower case.

 </p>
 </dd>
 <dt><code>-l</code></dt>
 <dt><code>--line-numbers</code></dt>
 <dd><a name="index-symbol-line-numbers"></a>
 <p>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.
 </p>
 </dd>
 <dt><code>-n</code></dt>
 <dt><code>-v</code></dt>
 <dt><code>--numeric-sort</code></dt>
 <dd><p>Sort symbols numerically by their addresses, rather than alphabetically
 by their names.

 </dd>
 <dt><code>-p</code></dt>
 <dt><code>--no-sort</code></dt>
 <dd><a name="index-sorting-symbols"></a>
 <p>Do not bother to sort the symbols in any order; print them in the order
 encountered.
 </p>
 </dd>
 <dt><code>-P</code></dt>
 <dt><code>--portability</code></dt>
 <dd><p>Use the POSIX.2 standard output format instead of the default format.
 Equivalent to &lsquo;<samp>-f posix</samp>&rsquo;.
 </p>
 </dd>
 <dt><code>-r</code></dt>
 <dt><code>--reverse-sort</code></dt>
 <dd><p>Reverse the order of the sort (whether numeric or alphabetic); let the
 last come first.
 </p>
 </dd>
 <dt><code>-S</code></dt>
 <dt><code>--print-size</code></dt>
 <dd><p>Print both value and size of defined symbols for the <code>bsd</code> output style.
 This option has no effect for object formats that do not record symbol
 sizes, unless &lsquo;<samp>--size-sort</samp>&rsquo; is also used in which case a
 calculated size is displayed.
 </p>
 </dd>
 <dt><code>-s</code></dt>
 <dt><code>--print-armap</code></dt>
 <dd><a name="index-symbol-index_002c-listing"></a>
 <p>When listing symbols from archive members, include the index: a mapping
 (stored in the archive by <code>ar</code> or <code>ranlib</code>) of which modules
 contain definitions for which names.
 </p>
 </dd>
 <dt><code>-t <var>radix</var></code></dt>
 <dt><code>--radix=<var>radix</var></code></dt>
 <dd><p>Use <var>radix</var> as the radix for printing the symbol values.  It must be
 &lsquo;<samp>d</samp>&rsquo; for decimal, &lsquo;<samp>o</samp>&rsquo; for octal, or &lsquo;<samp>x</samp>&rsquo; for hexadecimal.

 <dt><code>-V</code></dt>
 <dt><code>--version</code></dt>
 <dd><p>Show the version number of <code>nm</code> and exit.
 </p>
 </dd>
 <dt><code>-X</code></dt>
 <dd><p>This option is ignored for compatibility with the AIX version of
 <code>nm</code>.  It takes one parameter which must be the string
 <samp>32_64</samp>.  The default mode of AIX <code>nm</code> corresponds
 to <samp>-X 32</samp>, which is not supported by <small>GNU</small> <code>nm</code>.
 </p>
 </dd>
 <dt><code>--defined-only</code></dt>
 <dd><a name="index-external-symbols-2"></a>
 <a name="index-undefined-symbols-1"></a>
 <p>Display only defined symbols for each object file.

 </dd>
 <dt><code>--plugin <var>name</var></code></dt>
 <dd><a name="index-load-plugin"></a>
 <p>Load the plugin called <var>name</var> to add support for extra target
 types.  This option is only available if the toolchain has been built
 with plugin support enabled.
 </p>
 </dd>
 <dt><code>--size-sort</code></dt>
 <dd><p>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 <code>bsd</code> output format is used the size of the symbol
 is printed, rather than the value, and &lsquo;<samp>-S</samp>&rsquo; must be used in order
 both size and value to be printed.
 </p>
 </dd>
 <dt><code>--special-syms</code></dt>
 <dd><p>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 in the normal symbol lists.
 For example for ARM targets this option would skip the mapping symbols
 used to mark transitions between ARM code, THUMB code and data.
 </p>
 </dd>
 <dt><code>--synthetic</code></dt>
 <dd><p>Include synthetic symbols in the output.  These are special symbols
 created by the linker for various purposes.  They are not shown by
 default since they are not part of the binary&rsquo;s original source code.
 </p>
 </dd>
 <dt><code>--target=<var>bfdname</var></code></dt>
 <dd><a name="index-object-code-format"></a>
 <p>Specify an object code format other than your system&rsquo;s default format.
 See <a href="Target-Selection.html#Target-Selection">Target Selection</a>, for more information.
