You can also -just run ‘<samp>make check</samp>’ in a subdirectory of the object directory. -</p> - -<p>A more selective way to just run all <code>gcc</code> execute tests in the -testsuite is to use -</p> -<div class="smallexample"> -<pre class="smallexample">make check-gcc RUNTESTFLAGS="execute.exp <var>other-options</var>" -</pre></div> - -<p>Likewise, in order to run only the <code>g++</code> “old-deja” tests in -the testsuite with filenames matching ‘<samp>9805*</samp>’, you would use -</p> -<div class="smallexample"> -<pre class="smallexample">make check-g++ RUNTESTFLAGS="old-deja.exp=9805* <var>other-options</var>" -</pre></div> - -<p>The <samp>*.exp</samp> files are located in the testsuite directories of the GCC -source, the most important ones being <samp>compile.exp</samp>, -<samp>execute.exp</samp>, <samp>dg.exp</samp> and <samp>old-deja.exp</samp>. -To get a list of the possible <samp>*.exp</samp> files, pipe the -output of ‘<samp>make check</samp>’ into a file and look at the -‘<samp>Running … .exp</samp>’ lines. -</p> -<a name="Passing-options-and-running-multiple-testsuites"></a> -<h3 class="section">Passing options and running multiple testsuites</h3> - -<p>You can pass multiple options to the testsuite using the -‘<samp>--target_board</samp>’ option of DejaGNU, either passed as part of -‘<samp>RUNTESTFLAGS</samp>’, or directly to <code>runtest</code> if you prefer to -work outside the makefiles. For example, -</p> -<div class="smallexample"> -<pre class="smallexample">make check-g++ RUNTESTFLAGS="--target_board=unix/-O3/-fmerge-constants" -</pre></div> - -<p>will run the standard <code>g++</code> testsuites (“unix” is the target name -for a standard native testsuite situation), passing -‘<samp>-O3 -fmerge-constants</samp>’ to the compiler on every test, i.e., -slashes separate options. -</p> -<p>You can run the testsuites multiple times using combinations of options -with a syntax similar to the brace expansion of popular shells: -</p> -<div class="smallexample"> -<pre class="smallexample">…"--target_board=arm-sim\{-mhard-float,-msoft-float\}\{-O1,-O2,-O3,\}" -</pre></div> - -<p>(Note the empty option caused by the trailing comma in the final group.) -The following will run each testsuite eight times using the ‘<samp>arm-sim</samp>’ -target, as if you had specified all possible combinations yourself: -</p> -<div class="smallexample"> -<pre class="smallexample">--target_board='arm-sim/-mhard-float/-O1 \ - arm-sim/-mhard-float/-O2 \ - arm-sim/-mhard-float/-O3 \ - arm-sim/-mhard-float \ - arm-sim/-msoft-float/-O1 \ - arm-sim/-msoft-float/-O2 \ - arm-sim/-msoft-float/-O3 \ - arm-sim/-msoft-float' -</pre></div> - -<p>They can be combined as many times as you wish, in arbitrary ways. This -list: -</p> -<div class="smallexample"> -<pre class="smallexample">…"--target_board=unix/-Wextra\{-O3,-fno-strength\}\{-fomit-frame,\}" -</pre></div> - -<p>will generate four combinations, all involving ‘<samp>-Wextra</samp>’. -</p> -<p>The disadvantage to this method is that the testsuites are run in serial, -which is a waste on multiprocessor systems. For users with GNU Make and -a shell which performs brace expansion, you can run the testsuites in -parallel by having the shell perform the combinations and <code>make</code> -do the parallel runs. Instead of using ‘<samp>--target_board</samp>’, use a -special makefile target: -</p> -<div class="smallexample"> -<pre class="smallexample">make -j<var>N</var> check-<var>testsuite</var>//<var>test-target</var>/<var>option1</var>/<var>option2</var>/… -</pre></div> - -<p>For example, -</p> -<div class="smallexample"> -<pre class="smallexample">make -j3 check-gcc//sh-hms-sim/{-m1,-m2,-m3,-m3e,-m4}/{,-nofpu} -</pre></div> - -<p>will run three concurrent “make-gcc” testsuites, eventually testing all -ten combinations as described above. Note that this is currently only -supported in the <samp>gcc</samp> subdirectory. (To see how this works, try -typing <code>echo</code> before the example given here.) -</p> - -<a name="Additional-testing-for-Java-Class-Libraries"></a> -<h3 class="section">Additional testing for Java Class Libraries</h3> - -<p>The Java runtime tests can be executed via ‘<samp>make check</samp>’ -in the <samp><var>target</var>/libjava/testsuite</samp> directory in -the build tree. -</p> -<p>The <a href="http://sourceware.org/mauve/">Mauve Project</a> provides -a suite of tests for the Java Class Libraries.
