This is similar to the information provided by the @samp{nm} program,
although the display format is different. The format of the output
depends upon the format of the file being dumped, but there are two main
types. One looks like this:
@smallexample
[ 4](sec 3)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .bss
[ 6](sec 1)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000 fred
@end smallexample
where the number inside the square brackets is the number of the entry
in the symbol table, the @var{sec} number is the section number, the
@var{fl} value are the symbol's flag bits, the @var{ty} number is the
symbol's type, the @var{scl} number is the symbol's storage class and
the @var{nx} value is the number of auxilary entries associated with
the symbol. The last two fields are the symbol's value and its name.
The other common output format, usually seen with ELF based files,
looks like this:
@smallexample
00000000 l d .bss 00000000 .bss
00000000 g .text 00000000 fred
@end smallexample
Here the first number is the symbol's value (sometimes refered to as
its address). The next field is actually a set of characters and
spaces indicating the flag bits that are set on the symbol. These
characters are described below. The next field is another number
associated with the symbol, which for common symbols is the alignment
and for other symbol is the size. Finally the symbol's name is
displayed.
The flag characters are divided into 7 groups as follows:
@table @code
@item l
@itemx g
@itemx !
The symbol is local (l), global (g), neither (a space) or both (!). A
symbol can be neither local or global for a variety of reasons, eg
because it is used for debugging, but it is probably an indication of
a bug if it is ever both local and global.
@item w
The symbol is weak (w) or strong (a space).
@item C
The symbol denotes a constructor (C) or an ordinary symbol (a space).
@item W
The symbol is a warning (W) or a normal symbol (a space). A warning
symbol's name is a message to be displayed if the symbol following the
warning symbol is ever referenced.
@item I
The symbol is an indirect reference to another symbol (I) or a normal
symbol (a space).
@item d
@itemx D
The symbol is a debugging symbol (d) or a dynamic symbol (D) or a
normal symbol (a space).
@item F
@item f
@item O
The symbol is the name of a function (f) or a file (F) or an object
(O) or just a normal symbol (a space).
