<h5 class="subsubsection">2.18.4.3 Write other derived routines</h5>
|
||
|
|
|
||
|
|
<p>You will want to write other routines for your new hash table,
|
||
|
|
as well.
|
||
|
|
|
||
|
|
<p>You will want an initialization routine which calls the
|
||
|
|
initialization routine of the hash table you are deriving from
|
||
|
|
and initializes any other local fields. For the linker hash
|
||
|
|
table, this is <code>_bfd_link_hash_table_init</code> in <code>linker.c</code>.
|
||
|
|
|
||
|
|
<p>You will want a lookup routine which calls the lookup routine
|
||
|
|
of the hash table you are deriving from and casts the result.
|
||
|
|
The linker hash table uses <code>bfd_link_hash_lookup</code> in
|
||
|
|
<code>linker.c</code> (this actually takes an additional argument which
|
||
|
|
it uses to decide how to return the looked up value).
|
||
|
|
|
||
|
|
<p>You may want a traversal routine. This should just call the
|
||
|
|
traversal routine of the hash table you are deriving from with
|
||
|
|
appropriate casts. The linker hash table uses
|
||
|
|
<code>bfd_link_hash_traverse</code> in <code>linker.c</code>.
|
||
|
|
|
||
|
|
<p>These routines may simply be defined as macros. For example,
|
||
|
|
the a.out backend linker hash table, which is derived from the
|
||
|
|
linker hash table, uses macros for the lookup and traversal
|
||
|
|
routines. These are <code>aout_link_hash_lookup</code> and
|
||
|
|
<code>aout_link_hash_traverse</code> in aoutx.h.
