        <pre>It seems that Clang can be configured to only support 1 backend, and that if
you do so then pass -target <triple with a different arch>, that clang just
produces code for the configured arch without any warning or failure.  This led
to: <a href="https://lkml.org/lkml/2017/11/2/892">https://lkml.org/lkml/2017/11/2/892</a>

IMO, this should be a compiler error, if not at least a warning.</pre>
