+<h3 class="section">C.4 Specifying Names for Hosts and Targets</h3>
+
+<p>The specifications used for hosts and targets in the <samp>configure</samp>
+script are based on a three-part naming scheme, but some short predefined
+aliases are also supported. The full naming scheme encodes three pieces
+of information in the following pattern:
+</p>
+<div class="smallexample">
+<pre class="smallexample"><var>architecture</var>-<var>vendor</var>-<var>os</var>
+</pre></div>
+
+<p>For example, you can use the alias <code>sun4</code> as a <var>host</var> argument,
+or as the value for <var>target</var> in a <code>--target=<var>target</var></code>
+option. The equivalent full name is &lsquo;<samp>sparc-sun-sunos4</samp>&rsquo;.
+</p>
+<p>The <samp>configure</samp> script accompanying <small>GDB</small> does not provide
+any query facility to list all supported host and target names or
+aliases. <samp>configure</samp> calls the Bourne shell script
+<code>config.sub</code> to map abbreviations to full names; you can read the
+script, if you wish, or you can use it to test your guesses on
+abbreviations&mdash;for example:
+</p>
+<div class="smallexample">
+<pre class="smallexample">% sh config.sub i386-linux
+i386-pc-linux-gnu
+% sh config.sub alpha-linux
+alpha-unknown-linux-gnu
+% sh config.sub hp9k700
+hppa1.1-hp-hpux
+% sh config.sub sun4
+sparc-sun-sunos4.1.1
+% sh config.sub sun3
+m68k-sun-sunos4.1.1
+% sh config.sub i986v
+Invalid configuration `i986v': machine `i986v' not recognized
+</pre></div>
+
+<p><code>config.sub</code> is also distributed in the <small>GDB</small> source
+directory (<samp>gdb-13.2.90.20231008-git</samp>, for version 13.2.90.20231008-git).
