<h1 id="target-machine-information-target_machine-extends-build_machine">Target machine information (<code>target_machine</code> extends <a href="Reference-manual_builtin_build_machine.html"><ins><code>build_machine</code></ins></a>)</h1>
<p>Provides information about the target machine -- the machine on which
the compiled binary's output will run. Hence, this object should only
be used while cross-compiling a compiler. See
<a href="Cross-compilation.html">Cross-compilation</a>.</p>
<p>It has the same methods as <a href="Reference-manual_builtin_build_machine.html"><ins><code>build_machine</code></ins></a>.</p>
<p>When all compilation is 'native', all the methods return the same
values as <a href="Reference-manual_builtin_build_machine.html"><ins><code>build_machine</code></ins></a> (because the build machine is the host
machine and the target machine).</p>
<p>Note that while cross-compiling, it simply returns the values defined
in the cross-info file. If <code>target_machine</code> values are not defined in
the cross-info file, <code>host_machine</code> values are returned instead.</p>
