<p>Comment (by Roland Haas):</p>
<p>Unless objected I will close this ticket as “resolved” after 2019-7-14.</p>
<p>The test remains in <code>cctk_Config.h</code> which is maybe a bit unfortunate since that is not a file one would normally have checked. A test in <a data-is-external-link="true" href="http://configure.in" rel="nofollow">configure.in</a> (ideally not requiring actually running code, so that it also works with cross compiling) would be nicer. Something like:</p>
<div class="codehilite language-c"><pre><span></span><span class="cp">#if (defined __INTEL_COMPILER && \</span>
<span class="cp"> __INTEL_COMPILER_BUILD_DATE >= 20120731 && \</span>
<span class="cp"> __INTEL_COMPILER_BUILD_DATE < 20130728 && \</span>
<span class="cp"> !defined CCTK_INTEL_COMPILER_DONT_DISABLE_RESTRICT)</span>
<span class="cp">#error "icpc with failing __restrict__ handling detected"</span>
<span class="cp">#endif</span>
</pre></div>
<p>would do the trick.</p>
<p>There are no longer any production machines with intel compilers which fall into this range. The oldest compiler available is on shelob with /usr/local/compilers/Intel/composer_xe_2013.5.192/bin/intel64/icpc which has a build date of 20130607 and thus would fall into the range of “buggy” compilers (>= 20120731 and <20130728) but passes the standalone test for me (no matter what optimization level I choose).</p>
