<h3 class="section">7.10 Support for torture testing using multiple options</h3>
|
||
|
|
|
||
|
|
<p>Throughout the compiler testsuite there are several directories whose
|
||
|
|
tests are run multiple times, each with a different set of options.
|
||
|
|
These are known as torture tests.
|
||
|
|
<samp><span class="file">lib/torture-options.exp</span></samp> defines procedures to
|
||
|
|
set up these lists:
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><code>torture-init</code><dd>Initialize use of torture lists.
|
||
|
|
<br><dt><code>set-torture-options</code><dd>Set lists of torture options to use for tests with and without loops.
|
||
|
|
Optionally combine a set of torture options with a set of other
|
||
|
|
options, as is done with Objective-C runtime options.
|
||
|
|
<br><dt><code>torture-finish</code><dd>Finalize use of torture lists.
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
<p>The <samp><span class="file">.exp</span></samp> file for a set of tests that use torture options must
|
||
|
|
include calls to these three procedures if:
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>It calls <code>gcc-dg-runtest</code> and overrides <var>DG_TORTURE_OPTIONS</var>.
|
||
|
|
|
||
|
|
<li>It calls <var>${tool}</var><code>-torture</code> or
|
||
|
|
<var>${tool}</var><code>-torture-execute</code>, where <var>tool</var> is <code>c</code>,
|
||
|
|
<code>fortran</code>, or <code>objc</code>.
|
||
|
|
|
||
|
|
<li>It calls <code>dg-pch</code>.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>It is not necessary for a <samp><span class="file">.exp</span></samp> file that calls <code>gcc-dg-runtest</code>
|
||
|
|
to call the torture procedures if the tests should use the list in
|
||
|
|
<var>DG_TORTURE_OPTIONS</var> defined in <samp><span class="file">gcc-dg.exp</span></samp>.
|
||
|
|
|
||
|
|
<p>Most uses of torture options can override the default lists by defining
|
||
|
|
<var>TORTURE_OPTIONS</var> or add to the default list by defining
|
||
|
|
<var>ADDITIONAL_TORTURE_OPTIONS</var>. Define these in a <samp><span class="file">.dejagnurc</span></samp>
|
||
|
|
file or add them to the <samp><span class="file">site.exp</span></samp> file; for example
|
||
|
|
|
||
|
|
<pre class="smallexample"> set ADDITIONAL_TORTURE_OPTIONS [list \
|
||
|
|
{ -O2 -ftree-loop-linear } \
|
||
|
|
{ -O2 -fpeel-loops } ]
|
||
|
|
</pre>
