-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
    transitions 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.
