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

76 (for compatibility with the MIPS \fBnm\fP).
82 Decode (\fIdemangle\fP) low-level symbol names into user-level names.
83 Besides removing any initial underscore prepended by the system, this
84 makes C++ function names readable.
90 Display the dynamic symbols rather than the normal symbols. This is
91 only meaningful for dynamic objects, such as certain types of shared
96 Use the output format \fIformat\fP, which can be ``bsd'',
97 ``sysv'', or ``posix''. The default is ``bsd''.
98 Only the first character of \fIformat\fP is significant; it can be
99 either upper or lower case.

151 Sort symbols by size. The size is computed as the difference between
152 the value of the symbol and the value of the symbol with the next higher
153 value. The size of the symbol is printed, rather than the value.
158 .B "\-\-radix=\fIradix"
159 Use \fIradix\fP as the radix for printing the symbol values. It must be
160 ``d'' for decimal, ``o'' for octal, or ``x'' for hexadecimal.
