<h4 class="subsection">7.2.2 Selecting targets to which a test applies</h4>
|
||
|
|
|
||
|
|
<p>Several test directives include <var>selector</var>s to limit the targets
|
||
|
|
for which a test is run or to declare that a test is expected to fail
|
||
|
|
on particular targets.
|
||
|
|
</p>
|
||
|
|
<p>A selector is:
|
||
|
|
</p><ul>
|
||
|
|
<li> one or more target triplets, possibly including wildcard characters;
|
||
|
|
use ‘<samp>*-*-*</samp>’ to match any target
|
||
|
|
</li><li> a single effective-target keyword (see <a href="Effective_002dTarget-Keywords.html#Effective_002dTarget-Keywords">Effective-Target Keywords</a>)
|
||
|
|
</li><li> a logical expression
|
||
|
|
</li></ul>
|
||
|
|
|
||
|
|
<p>Depending on the context, the selector specifies whether a test is
|
||
|
|
skipped and reported as unsupported or is expected to fail. A context
|
||
|
|
that allows either ‘<samp>target</samp>’ or ‘<samp>xfail</samp>’ also allows
|
||
|
|
‘<samp>{ target <var>selector1</var> xfail <var>selector2</var> }</samp>’
|
||
|
|
to skip the test for targets that don’t match <var>selector1</var> and the
|
||
|
|
test to fail for targets that match <var>selector2</var>.
|
||
|
|
</p>
|
||
|
|
<p>A selector expression appears within curly braces and uses a single
|
||
|
|
logical operator: one of ‘<samp>!</samp>’, ‘<samp>&&</samp>’, or ‘<samp>||</samp>’. An
|
||
|
|
operand is another selector expression, an effective-target keyword,
|
||
|
|
a single target triplet, or a list of target triplets within quotes or
|
||
|
|
curly braces. For example:
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample">{ target { ! "hppa*-*-* ia64*-*-*" } }
|
||
|
|
{ target { powerpc*-*-* && lp64 } }
|
||
|
|
{ xfail { lp64 || vect_no_align } }
|
||
|
|
</pre></div>
