Auxiliary table entries
An auxiliary table entry
of a symbol contains the same number of bytes
as the symbol table entry.
However, unlike symbol table entries,
the format of an auxiliary table entry of a symbol depends on its
type and storage class.
They are summarized in
Table 7-27, ``Auxiliary symbol table entries''.

In
Table 7-27, ``Auxiliary symbol table entries'',
tagname means any symbol name including the special
symbol .xfake,
and fcname and arrname represent any symbol name
for a function or an array respectively.
Any symbol that satisfies more than one condition in
Table 7-27, ``Auxiliary symbol table entries''
should have
a union format in its auxiliary entry.
