<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-10.1.90.20201028-git</samp>, for version 10.1.90.20201028-git).
