@table @code
@item A
Absolute.
The symbol's value is absolute, and will not be changed by further
linking.
@item B
BSS (uninitialized data).
The symbol is in the uninitialized data section (known as BSS).
@item C
Common.
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
--warn-common in @ref{Options,,Linker options,ld.info,The GNU linker}.
@item D
Initialized data.
The symbol is in the initialized data section.
@item G
The symbol is in a 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.
@item I
Indirect reference.
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.
@item N
The symbol is a debugging symbol.
@item R
The symbol is in a read only data section.
@item S
The symbol is in a uninitialized data section for small objects.
@item T
Text (program code).
The symbol is in the text (code) section.
@item U
Undefined.
The symbol is undefined.
@item W
The symbol is weak. 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.
@item -
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;
for more information, see @ref{Top,Stabs,Stabs Overview,stabs.info, The
``stabs'' debug format}.
@item ?
The symbol type is unknown, or object file format specific.
