71<h3 class="section">C.4 Specifying Names for Hosts and Targets</h3>
72
73<p>The specifications used for hosts and targets in the <samp>configure</samp>
74script are based on a three-part naming scheme, but some short predefined
75aliases are also supported.  The full naming scheme encodes three pieces
76of information in the following pattern:
77</p>
78<div class="smallexample">
79<pre class="smallexample"><var>architecture</var>-<var>vendor</var>-<var>os</var>
80</pre></div>
81
82<p>For example, you can use the alias <code>sun4</code> as a <var>host</var> argument,
83or as the value for <var>target</var> in a <code>--target=<var>target</var></code>
84option.  The equivalent full name is &lsquo;<samp>sparc-sun-sunos4</samp>&rsquo;.
85</p>
86<p>The <samp>configure</samp> script accompanying <small>GDB</small> does not provide
87any query facility to list all supported host and target names or
88aliases.  <samp>configure</samp> calls the Bourne shell script
89<code>config.sub</code> to map abbreviations to full names; you can read the
90script, if you wish, or you can use it to test your guesses on
91abbreviations&mdash;for example:
92</p>
93<div class="smallexample">
94<pre class="smallexample">% sh config.sub i386-linux
95i386-pc-linux-gnu
96% sh config.sub alpha-linux
97alpha-unknown-linux-gnu
98% sh config.sub hp9k700
99hppa1.1-hp-hpux
100% sh config.sub sun4
101sparc-sun-sunos4.1.1
102% sh config.sub sun3
103m68k-sun-sunos4.1.1
104% sh config.sub i986v
105Invalid configuration `i986v': machine `i986v' not recognized
106</pre></div>
107
108<p><code>config.sub</code> is also distributed in the <small>GDB</small> source
109directory (<samp>gdb-10.2.90.20210621-git</samp>, for version 10.2.90.20210621-git).
